Use VC5 to start the sequence
Use VC5 to start the sequence
Many large-scale applications have enabled seals such as Word, etc., MPS software and VC equivalents. Through the opening cover, in addition to the display of the programming screen name and version, it is also possible to avoid a large amount of data initialized by the application program startup. The wait for a long time, and adds a multi-dynamic characteristic and specializi style. Given that the VC development tool should be widely used, this is an example of the prevention of the latent surface with VC5 as an example.
---- 1. Making the sealing position
---- Mechanic Application Program Lift Removal Frame Real Color Bitmap, Recording the height and width of bitmap, and build a document such as his sounds.
---- 2. Construction of the application
---- Use the file > New menu to build a multi-document application program frame named Start, and use the class wizard AppWizard to increase the new class CSPlashWnd of Generic CWnd, will new classes The file is renamed Splash.h and Splash.cpp and adds WM -CREATB and WM -PAINT messaging function.
---- 3. Define variables and functions
---- Defining the variables and functions of the following in Splash.h:
PUBLIC:
Bool create (CWND * pParentWnd = NULL);
Handle HbitsSrc;
LPSTR PBITSRC;
UINT IW, IH;
---- 4. Jianli launched window window
---- Add Create Function in Splash.cpp, build a pop-up window of the display bitmap:
#Include "windowsx.h" / / increasing expansion window
...
Struct {/ / bitmap file head structure
BitmapInfoheader Header;
} Info;
Bool csplashWnd :: Create (CWND * PParentWnd)
{/ / Set up a population window
Return Createex (0, AFXREGISTERWNDCLASS (0, AFXGetApp () -> LoadStandardCursor
(IDC_ARROW),
NULL, WS_POPUP | WS_VISIBLE, 0, 0, 672, 480,
PparentWnd -> getsafehwnd (), null;
}
INT CSPLASHWND :: OnCreate (lpcreatestruct lpcreatestruct)
{... ...
/ / TODO: Add Your Specialized Creation Code Here
CenterWindow (); / / make the pop-out window
Return 0;
}
---- 5. Functory function
---- Treatment of the pattern function in splash.cpp, preparation for display of bitmap: csplashwnd :: csplashWnd () / / full parsing function
{IW = 672; IH = 480; / / bitmap width and high degree
Info.Header.bisize = sizeof (BitmapInfoHead);
Info.Header.biWidth = IW;
Info.Header.biheight = IH;
Info.Header.Biplanes = 1L;
Info.Header.biBitcount = 24L;
HbitsSRC = :: Globalalloc (ghnd, (long) (iW * ih * 3)); / / distribution memory
PBITSRC = (LPSTR) :: Globalock (hbitsSRC); / / plus lock memory
}
CSPLASHWND :: CSPlashWnd ()
{:: globalunlock (hbitssrc); / / unlock memory
:: GlobalFree (hbitssrc); / / Release memory
}
---- 6. Display true color bitmap
---- Take the onpaint function in splash.cpp, realize the real color bitmap display:
Void csplashwnd :: onpaint ()
{... ... / / tDO: Add Your Message Handler Code Here
Cfile FBMP;
FBmp.Open ("c: //windows//emc1.bmp", cfile :: moderad |
Cfile :: typebinary | cfile :: ShareExClusive); / / Open the document
FBmp.seek (54, cfile :: begin); / / bit map file header is 54-byte
FBmp.Readhuge (Pbitssrc, (long) (iW * ih * 3)): / / read file
FBmp.close (); / / Close file
Hbitmap hbitmap = :: createdibitmap (dc.m_hdc,
(BitMapInfoHeader Far *) & (Info.Header), CBM_INIT,
Pbitssrc, (lpbitmapinfo) & info, dib_rgb_colors; / / build bitmap
HDC hmemdc = :: createcompatibledc (dc.m_hdc); / / Construction
Hbitmap hbitmapold = selectbitmap (hmemdc, hbitmap); / / Select an object
:: Stretchblt (Dc.m_HDC, 0, 0, IW, IH, HMEMDC, 0, 0, IW, IH, SRCCOPY);
/ / Display true color bitmap
:: DeleteObject (SelectObject (HMEMDC, HbitMapold); / / Delete bitmap
}
---- 7. Playing the window
---- Add code in mainfrm.h, prepare for display and withdrawing pop-out window:
Class CsplashWnd: / / flash window class
...
Class CMAINFRAME: PUBLIC CMDIFRAMEWND
{... ...
Pubiic:
CSPlashWnd SplashWnd; / / Sound Class
}
---- 8. Reality of the real color cover
---- Increase the display of the pop-up window, play the sound music, delay function, and withdrawal pop-up window in mainfrm.cpp, to realize the entire process of real color sealing :
#Include "splash.h" / / new class support
#Include "mmsystem.h" / / multimedia support
#Pragma comment (lib, "winmm.lib") / / multimedia support
...
INT CMAINFRAME :: OnCreate (lpcreatestruct lpcreatestruct)
{
SplashWnd.create (this); / / creation population window
SplashWnd.ShowWindow (sw_show); / / Display pop-up window
SplashWnd.UpdateWindow (); / / update pop-up window
INT DD = SNDPLAYSOUND ("c: //windows/reminder.wav", SND_ASYNC | SND_LOOP);
/ / Distread WAV file
IF (DD == false) {/ / parameter SND_ASYNC | SND_LOOP can be looped
AfxMessageBox ("Wav WAM Faults");
}
:: Sleep (2000); / / Circuit sleep 2 seconds
... / / Application Program Initialization
DD = SNDPLAYSOUND ("", SND_ASYNC); / / Final broadcast .WAV file
SplashWnd.destroyWindow (); / / withdrawal pop
Return 0;
}
---- The whole real color start sealing is completed, if you need to add and move and move
The subtitles and other multimedia functions.
