INSTALLSHIELD internal library function 2 user interface functions
The user interface function allows the user to customize a specific error message and the error frame title. However, some internal error messages encountered in the installation development cannot be modified by the user interface function. This part mainly describes the grammar, description, parameters of the user interface function.
2.1 Disable function
Syntax: disable (nconstant)
Description: The disable function is invalid by the user interface object or installation characteristics specified by the parameter nConstant.
parameter:
NConstant
Specifies that the user interface object or the operative characteristic makes it invalid, one of the following predefined constants in this parameter location:
BackButton: The Back button displayed in some internal dialogs is invalid (even if it is ash ash display), the Back button default is valid.
Background: Invuse and hide the installation master background window. Note: This parameter does not work when the installation is in full screen.
Billboard: Cancel the display of the player during the installation process.
DialogCache: The conversation buffer is invalid. For a detailed description of the dialog buffer, see Enable.
Hourglass: Make the cursor from a "busy" cursor (default to the hourglass cursor) to a standard cursor (default is a pointer).
IndvFileStatus: Do not display the path and file names in the schedule indicator (Status).
Logging: Do not record the uninstallation information, so that the information is not recorded in the uninstall log file. Note: The recording function is automatically set by the function deinstallStart to be valid. The record unloading information is invalid before calling DeinstallStart, because when DeinstallStart is called, the recording function will be automatically activated, and the user must handle the record before the uninstall operation should not be recorded.
NextButton: Make the NEXT button of some internal dialogs (make it ash ash). The next button is set to be valid.
SelfregisterBatch: The batch method of registering from the registration file is invalid. See ENABLE for details.
SATAUS: Enables standard progress indicators (state bar) to be invalid and hidden.
Statusdlg: The progress indicator (status bar) in the form of the dialog is invalid and hidden.
STATUSEX: Disables replace the progress indicator (Status) in the Display Installation Status dialog box.
Statusold: The progress indicator (status section) that makes the original style is invalid and hidden.
return value:
0: Description function successfully prohibits the user interface object or installation characteristics specified by the parameter nConstant.
<0: Description function failed to disable the user interface object or installation characteristics specified by the parameter nConstant.
annotation:
• If the disable function is called in the user's script to disable the next or the Back button, the button is disabled in all dialogs after the function is called, and the user needs to call Enable with the corresponding constant to activate the NEXT or BACK button.
· DialogCache does not work in a dialog box without a Next or Back button.
2.2 enable function
Syntax: enable (nconstant);
Description: Enable function activates the user interface object or installation characteristic specified by the parameter nConstant.
parameter:
NConstant
Specify the user interface object or operational feature you want to activate. One of the following predefined constants in this parameter location:
BackButton: Activate the Back button in some internal dialogs. The BACK button is activated by the default, but it can be disabled by calling the Disable function. Background: When the installation is in the window mode, the installation master background window is displayed. This constant does not work when the installation is the default full-screen mode. To activate the window mode, you must call Enable in a constant DEFWINDOWMODE or FULLWINDOWMODE.
DefWindowMode: Configure the main background window as a standard window with title bar. If the background window is activated, its appearance will change immediately. If the background window is disabled, the screen will not be modified until the ENABle is called by the ordinary background.
DialogCache: Activate dialog buffer mechanism, which eliminates the screen blinking between the display dialog box. This screen flashes in the title bar running in the window mode. Note The dialog buffer mechanism is only working on the dialog box with the back and Next. The default dialog buffer is disabled.
FullWindowMode: Sets the master background window to a maximum window with a title bar. If the background window is activated, its appearance will change immediately. If the background window is disabled, the screen will not be modified until the ENABLE is called with the ordinary background.
Hourglass: Make the cursor to "Busy" cursor, default is a hug gauge.
IndvFileStatus: When the COMPONENTTRANSFERDATA, COPYFILE, or XCopyFile and the progress indicator are activated, the full-qualified name (displayed in the second row of the progress indicator) is activated. Note that in a installer running an event-based script, ComponentTransferData is automatically called.
Logging: Activation deposits the uninstall record function. When the storage feature is activated, the operation result of the unloading record stored in InstallShield will be recorded in the uninstall log file and will be reversed during the uninstall. Automatically call the DeinstallStart activation storage; therefore, you don't need to manually activate the deposit. Unless you have previously disabled it with a disable function.
NextButton: Activates the next NEXT button in some internal dialogs. Next is activated by twisting province.
SelfregisterBatch: Activate the batch method for registering from registered files. This method uses to avoid dependencies associated with the registration file. By default, standard (non-batch) is registered.
More information about batch methods is as follows:
· In the file group pane, highlight your file group folder for your self-registration file. Its property sheet is open on the right.
· Double-click the Self-Registered domain, open from the registration page.
· Select "Yes, all the files in this file group all the self-registering" single button.
· Open your installation script (find setup.rul in the Scripts pane).
`Call the Enable function with the selfregisterbatch option before you transfer the file. All self-registration files are placed in an internal queue, that is, they will be registered immediately when they are installed. (In an event script, the OnBegin handler is called before being called.)
After transferring the file, call the DO function with the SelfregistrationProcess option. When you call DO (SelfregistrationProcess), InstallShield registers all self-registration files. If the DO is called, the system variable Batch_install is equal to TRUE (indicating that a reboot is required to complete the installation), then the registration file is delayed to the restart. After you call DO (SelfRegistrationProcess), you can check if you have successful success. If DO is fails due to any reason, it will return -1. The names of those self-registration failures are saved in the system variable errorfilename, separated by a semicolon.
For example, the following code registers all from the registration file in the file media library.
// Enable Batch Method to Queue Self-Registering Files.
Enable (SelfregisterBatch);
// install files.
NResult = ComponentTransferData (Media);
// register the files, check for errors.
IF DO (SelfregistrationProcess) <0 THEN
SZMSG = "File (s) failed to self-register: / n" ErrorFileName;
MessageBox (Szmsg, Warning);
Endif;
STATUS: Activate the display standard progress indicator (status bar).
Statusdlg: Activate the progress indicator of the display dialog style (status bar).
Statusex: Activate the Display Installation Status dialog to replace the progress indicator (status bar).
Statusold: Activate the old style progress indicator (status bar), it doesn't have a Cancel button.
return value:
0: Indicates that the function successfully activates the user interface object or installation characteristics specified by the parameter nConstant.
<0: Indicates that the function fails to activate the user interface object or installation characteristics specified by the parameter nConstant.
annotation:
· When the default, the installation is running in full screen; the main background window is displayed as a full screen window without the title bar. In this way, the main mounting window cannot be adjusted and there is no visible title bar. To activate the window mode, you must call Enable in a constant DEFWINDOWMODE or FULLWINDOWMODE.
• If you call the disable function in your script to disable the Next or Back button, this button is disabled in all dialogs after the function is called, to activate the Next or Back button, you need to call Enable with the corresponding constant.
· DialogCache does not work in a dialog box without a Next or Back button.
2.3 FindWindow
Syntax: FindWindow (SzclassName, Szwinname);
Note: The FindWindow function provides a method of getting a window handle by specifying a window class and window name and window name to a Senior Developer. If you know an application's window class and window name, you can get its handle. Then you can send information directly to the window through this handle.
parameter:
SzclassName
Specifies the name of the class belonging to the window. If you specify as "any class", an empty string is passed at this parameter.
Szwinname
Specify window headings. To return the handle of the top-level window in the specified class, a null string ("") is transmitted at this parameter.
return value:
XXXX: Handle of the window. NULL (0): FindWindow cannot find the window according to the specified window name and class name.
annotation:
· To find a class and name of a window, run the Microsoft Spy.exe program.
2.4 PlaceBitmap
Grammar: PlaceBitmap (SZNAME, NID_BITMAP, NDX, NDY, NDRAWOP);
Description: The PlaceBitmap function is inserted into an image in the installation window. The image source is specified by szname, which can be a bitmap file (.bmp), a meta file (.WMF), or a dynamic link library (.dll). InstallShield supports 2 colors, 16 colors, 256 colors and true color bitmaps (Bitmap). 2 colors, 16 colors, 256 color bitmaps may have a transparent portion.
The transparent bitmap is useful when displaying an image that can be displayed in combination with the background window. The pixels matching the specified transparent color matching in the bitmap are not displayed; the background pixels in this position are maintained visible. In installation, a technically design often uses a transparent bitmap containing the company name and logo as a title of the installation window.
To specify a transparent bitmap, you must pass a constant Bitmapicon to the parameter ndrawop location. You must also consider what color in a bitmap is placed transparent. The default transparent color is PURPLE (RGB (255, 0, 255)). To specify a different transparency, you can specify using the parameters szname described below.
Because the metafile is drawn, instead of placement, they are inherently transparent. If Bitmapicon is specified as a primitive file, the parameter is ignored.
Many special display effects of non-transparent bitmaps can be displayed by using the SetDisPlayeffect function. This function also provides a limited display effect for the primitive.
The location of the middle map can be specified in two ways:
· Pass the position constant by parameter ndrawop.
• Transfer vertical and horizontal displacement from the edge of the installation window by parameter NDX and NDY.
You can usually remove any bitmap files and chart files that are no longer needed by calling the PlaceBitMap (set the parameter nDRAWOP to REMOVE). It is recommended to delete a unwanted bitmap, even if the bitmap can be completely covered by other bitmaps, because the palette entry of the first bitmap is only released after the bitmap is deleted.
A true color bitmap is displayed on a system running in a 16-color or 256 color mode, only uses those valid in the palette; do not assign additional colors to the bitmap, even if the additional palette entry is Effective. If you want to have a 24-bit map, you can run in a 16-color or 256 color system, which requires a version of 16 colors or 256 colors of the bitmap. Then you call getSystemInfo to determine the current color mode before selecting the parameter colors to be displayed.
parameter:
Szname
Specifies the list of bitmap files to be displayed, the fully qualified name or dynamic link of the element file. InstallShield identifies bitmap files and chamfer files by extension. The bitmap file must have an extension .bmp, the chamber file must have an extension .WMF. Dynamic link must have an extension .dll. If a file name is specified as no extension, InstallShield will assume that its extension is .dll.
To specify a candidate transparent color, place a semicolon (;) after the file name (;), followed by a set of RGB color values (RGB colors are specified by three values, separated by commas). This color is used as a transparent color of the bitmap specified by SZNAME. Note that it does not work for the bitmap that has been displayed, nor does it become the default transparent color of the bitmap displayed by the PlaceBitmap.
The following parameters specify white to transparent color:
Supportdir ^ "Bitmap.BMP; 255, 255, 255"
This parameter is ignored when NDRAWOptions is set to REMOVE. NID_BITMAP
Specifies the resource ID of the bitmap resides in one .dll. If the source point of the bitmap is a primitive file or bitmap file, specify a value that is not used in the currently displayed image; all the images displayed simultaneously must have its unique ID number. When NDRAWOptions is set to REMOVE, this parameter must contain the ID of the image displayed.
NDX
When NDRAWOP is set to Lower_LEFT, LOWER_RIGHT, UPPER_LEFT, or UPPER_RIGHT, specify the horizontal distance between the installation window edge and the image edge; otherwise the parameter is ignored.
NDY
When NDRAWOP is set to Lower_LEFT, LOWER_RIGHT, UPPER_LEFT, or UPPER_RIGHT, specify a vertical distance between the installation window edge and the edge of the image; otherwise the parameter is ignored.
NDRAWOP
It is pointed out of the location of the location, set the placement option, or delete the previously placed bitmap. Pass the parameter to pass the following predefined constants:
Bitmapicon: Indicates that the bitmap has a transparent part. The user can combine this constant and other constants (except Tiled, Fullscreen, or FullScreensize) with a bitwise or operator (|). When Bitmapicon and one of those constants, the standing or operation is ignored, but only Bitmapicon is used.
TILED: The bitmap is in the main installation window. This constant is usually used to create a installation background. When the constant is specified, even if the location option is ignored, the special effect has been activated by SetDisplayTeffect, and the bitmap is still displayed.
Fullscreen: Drag image makes it fills the entire installation window. The image is not adjusted by the image. If a bitmap image is smaller than the InstallShield main window, it is set in the window, the background is filled by the current background color. The default is dark blue (Teal); can be changed by using the setColor function. When this constant is specified, the location option is ignored, even if a special effect has been activated by SetDisPlayeffect, the bitmap is still displayed normally.
Fullscreensize: Drag and stretch image make it filled with the entire installation window. When this constant is specified, the location option is ignored, even if a special effect has been activated by SetDisPlayeffect, the bitmap is still displayed normally.
CENTERED: Place the bitmap in the center of the InstallShield installation window.
Lower_Left: Place the bitmap in the lower left corner of the InstallShield installation window.
Lower_right: Place the bitmap in the lower right corner of the InstallShield installation window.
Upper_left: Place the bitmap at the top left of the InstallShield installation window.
Upper_right: Place the bitmap in the upper right corner of the InstallShield installation window.
REMOVE: Delete a previously placed bitmap or element. Any special effects activated by SetDisPlayeffect are ignored.
return value:
0: Indicates that the function successfully found and place the image.
<0: Indicates that the function cannot be found or placed.
annotation:
· Call setDisplayeffect to set special effects for non-tile, full screen, transparent bitmap; users can also use it to set limited special effects for primitives.
· InstallShield does not support 24-bit transparent bitmaps. If the user contains transparent colors in a 24-bit position, the Bitmapicon constant is specified, which will be normally displayed.
• When you place a 256-color bitmap in the system running 256 color mode, InstallShield will try to assign the palette to the system palette of the bitmap. If multiple 256 color bitmaps are placed, INSTALLSHIELD will attempt to merge the palettes of all visual bitmaps into the system palette, priority to the most recently placed bitmap. This behavior may result in a color of the previously placed bitmap when other bitmaps are displayed. • In a 256-color pattern of 256-color jitter, a bitmap containing many colors may result in some palette inlets used in the background being reassigned; this can cause a gradient effect in the background. . If the installation contains a bitmap using multiple colors, do not use 256 color jitter background when they run in the 256 color system.
• The system palette only exists in a system running in a 256-color mode. There is no system palette in the system running in Windows 95 and after high color or true color mode and running in 65525 (16-bit) color mode. These systems do not need to consider the palette handle problem. Colors use the RGB value to display directly.
· Because the element file is colored, they do not include a custom palette. When a chamber is displayed in a 256-color system, no palette processing occurs; the element file is drawn in use with the color used in the current palette. Thus, to run in a 256 color system, the user should not use the display color different from the standard 16 color in the installer.
2.5 PlaceWindow
Syntax: PlaceWindow (NOBJECT, NDX, NDY, NCORNER);
Description: The PlaceWindow function changes the location of the user interface object, including the billboard. Specify the edge of the object with the edge of the screen with NDX and NDY.
parameter:
NOBJECT
Specifies the object to be changed. One of the following predefined constants in this parameter location:
Background: Moving background window.
Billboard: Sets the location of the billboard used in the file transfer process.

STATUS: Move progress indicator.
Statusdlg: Mobile dialog style progress indicator.
STATUSEX: Move the Install Status dialog.
STATUSOLD: The progress indicator of the old style.
When you call PlaceWindow to move the progress indicator or status dialog, it is sure that the correct constant is passed for the feedback object you activated in the installation. For example, if you call Enable (Statusold), you must pass Statusold to PlaceWindow.
NDX
The horizontal distance between the edge and the edge of the object is specified by pixel points.
NDY
The vertical distance between the side of the object is specified by the pixel point and the edge of the screen.
NCORNER
Specifies which angular amount from the distance indicated by NDX and NDY. One of the following predefined constants in this parameter location:
Lower_Left: NDX from the left side of the InstallShield main window, quantify NDY from the bottom end.

Upper_left: NDX from the left side of the InstallShield main window, quantity from the top end.
Upper_right: NDX from the right side of the InstallShield main window, quantity from the top end.
return value:
0: Indicates that the function successfully changes the location of the object.
<0: Indicates that the function failed to change the location of the object.
annotation:
· When using this function, you should realize that a installer is running under different screen resolutions. You may want to determine the screen range before placing the object. The distance is the distance between the edges of the target edge and the designated screen corner. · The user cannot locate the message box in this function because the message box is created by the Windows / PM API of this unit. The location of a message box is determined by Windows / PM, not under InstallShield control. In addition, users cannot locate a custom dialog with this function.
2.6 Playmmedia
Grammar: Playmmedia (NTYPE, SZFILENAME, NOPERATION, NRESERVED);
Description: Playmmedia function plays a sound or AVI file. MIDI or WAVE type sound files and AVI (video) files can be played in asynchronously in synchronous mode. This function can also be used to play a file continuously. In order to achieve this, a flag can be bitten or to indicate that the file is played in a continuous manner.

2.14 SetStatusWindow
Syntax: setStatusWindow (NPERCENT, SZSTRING);
Description: The setStatusWindows function is a progress indicator (Status section) Set the initial value or current value of the percentage of the indicator and specifies the current message displayed at the progress indicator (status bar).
The installation of the file must be called to call SetStatusWindows before the file transfer is started, which is the highest row to set the percentage percentage of the indicator and clear the indicator. No need to call SetStatusWindows. When the file of each component is loaded, the 'status text' character of the component is automatically displayed at the highest line of the status bar.
The installer that uses the Copyefile or XcopyFile function is loaded with the file between the CopyFile or XcopyFile, which may need to call SetStatusWindows multiple times to change the information of the most high line of indicators.
Your installer should also call the STATUSUPDATE function to activate the automatic update of the percentage completion indicator during the file transfer process. In order to make the name and path of the installed file in the second row of the status bar, you need to call the Enable function before transferring the file before transferring the file. After these calls, the percentage completion indicator is smoothed in the file transfer process, and the file name of each file will be displayed when transmitted. parameter:
NPERCENT
Specifies a value between 0 and 100 to indicate the percentage of the percentage to complete the indicator. To change the information displayed in the most high line of state strips, the parameter is specified to -1.
Szstring

Description: The SetTitle function displays a title in the main window title bar according to NColor or in the main window.
parameter:
Sztitle
Specifies a title displayed in the main window title bar or main window. If the title is displayed in the title bar of the window, you must specify a predefined constant backgroundCaption in the third parameter location. If the title of a title column does not match the available space, it will be tail from the right and terminate it in order to omit. The default title bar title is "Installation".
When a color value is transmitted to the third parameter, the title is displayed on the top of the main window. The title relative to the main window will be displayed from the right truncation. In order to create a topic that occupies multi-line, you can embed the wrap in the interoperability you want.
Npointsize
Take a point to specify the font size of the title displayed in the main window. It is recommended to have 24 points. Note that the parameter is ignored when the third parameter is BackgroundCaption.
Ncolor
Specify a color or predefined constant backgroundcapion. To indicate that the sztitle value should be displayed in the main window title bar, the predefined constant backgroundcaption is passed in this parameter location. When the user specifies the BackgroundCaption, NpointSize is ignored; the color and font size of the title bar title will be determined by the system settings of the end user. Note that this option is invalid in the installer that is not running on the window mode; see the following annotations.
To indicate that the sztitle value should be displayed in the main window, specify the color of the title by passing one of the following predefined constants: Black, Blue, Green, Magenta, Red, Yellow, or White. Users can also pass the RGB function in this parameter location to specify a custom color, as shown in the following example:
Settitle ("FantasticApp", 24, RGB (78, 125, 161);
return value:
0: Indicates that the function is successfully set the title.
<0: Indicates that the function is not set to set the title.
annotation:
· Not running in the installation in window mode, the third parameter is set to the backgroundCaption to call Settitle invalid. To run the installer in a standard window, you must first call Enable in parameter defWindowMode or FullWindowMode, then call Enable to display the window with parameter background.
· Use setColor to set up the background color of your installed.
· Use setFont to set the fonts and font styles of the title displayed in the background window.
2.16 SizeWindow
Syntax: SizeWindow (NOBJECT, NDX, NDY);
Note: Use the SizeWindow function to change the size of a particular user interface element. Specify new sizes in pixel points.
parameter:
NOBJECT
Specifies the object to be adjusted. One of the following predefined constants in this parameter location:
Background: Identifies the main background window.
Metafile: Identify a bunker used in the file transfer process. SizeWindow does not support bitmap file (.bmp). This parameter does not have any effect on the element file displayed with the SDBITMAP function. SDBitmap automatically adjusts the size of the displayed element file.
MMEDIA_AVI: Sets the size of the window to play the next AVI file. All AVI video is displayed in a default size. Changing the size may change the effective resolution and brightness of the video.
NDX
Specify the horizontal size of the object with pixel points.
NDY
Specify the vertical size of the object in pixel points.
return value:
0: Indicates that the function is successfully adjusted window size.
<0: Indicates that the function has not been adjusted to adjust the window size.
annotation:
· The installer may run at a plurality of different screen resolutions. Therefore, you need to use the getExtents function to determine the full screen size of the screen, then use the ratio in your SizeWindows function call to specify the size of the user interface object.
· This function is recommended to senior developers.
2.17 statusupdate
Syntax: statusupdate (blink, nFinalPercent);
Description: The StatusUpdate function is activated or disables the connection between file transfer operations and status strips. When Blink is ON, the connection is activated and the NFinalPercent indicates a last percentage displayed at the end of the next file transfer. During the file transfer, the status bar is smoothed from its current value to the value specified by NFinalPercent. When BLINK is OFF, the connection is disabled and the progress indicator of the status bar will not be updated automatically in subsequent file transfer.
If the status bar in the file transfer is activated, StatusUpdate is called before each call CopyFile or XcopyFile. Before calling the ComponentTransferData transfer file, the belt parameter is called on and 100; this will make the status bar smoothly to 100% in the installed file transfer phase. Note that in a run based on an event script, ComponentTransferData is automatically called.
parameter:
Blink
Specifies whether to activate or disable the connection between file transfer operations and status strips. One of the following predefined constants in this parameter location:
ON: The schedule of the specified state strip must be connected to the file transfer operation.
Off: Specifies the connection between the progress indicator of the disable status bar and the file transfer operation. The connection is kept until it is re-established by a repartial call to the StatusUpdate with parameter Blink is ON.
The status strip can be manually updated by calling SetStatusWindow.
NFinalPercent
Specifies that when BLINK is ON, the progress indicator of the status bar must be achieved at the end of the next file transfer operation. If the value passed to the NFinalPercent is less than the current value of the progress indicator of the status bar, the progress indicator will not change. When Blink is OFF, the parameter is ignored.
return value:
0: Indicates that the function is successful.
<0: Indicates that the function is unsuccessful.
annotation:
· This function operates by calculating the total number of bytes transmitted by any file transfer function. It then calculates the maximum value from the current position of the progress indicator to NFinalPercent, and needs to increase the progress indicator every time.
• The StatusUpdate function cannot work with VerupdateFile, VersearchandUpdatefile. When you call those functions, you must disable the status bar or manually update it.
