1. How to set the boundary of a from
Form has a total of seven different border style to set you, you can run through generations at design time.
The code dynamics set it. These seven border styles are:
None (System.Windows.Forms.Formborderstyle.none)
Fixed 3D (System.Windows.Forms.FormBorderstyle.fixed3D)
Fixed Dialog (System.Windows.Forms.FormBorderstyle.fixedDialog)
Fixed Single (System.Windows.Forms.FormBorderstyle.fixedsingle)
Fixed Tool Window (System.Windows.Forms.FormBorderstyle.
FIXEDTOOLWINDOW)
Sizable (System.Windows.Forms.FormBorderstyle.sizable)
Sizable Tool window
(System.Windows.Forms.FormBorderstyle.sizableToolWindow)
Set the formborderstyle attribute in the Properties Window of the VS.NET ID in the design mode
Yes.
You can use the code under the mode of operation:
DLGBX1.FormBorderstyle = system.windows.forms.formolderstyle.
FixedDialog
There is no big change in this seven boundary type VB6, and you need a different enumeration in the mode of operation.
Variables are set.
2. How to build a transparent from FROM
You can do this at design time and running at both ways.
Design time, you can set the opacity property to reach this at the VS.NET IDE's Properties Window.
Effect. This value is completely transparent from 0.0 to 1.0. 0, 1.0 is completely opaque.
At runtime you can use the following encoding settings to set the Opactiy property of the form. Specific:
FRMTRANSPARENTFORM.OPACITY = 0.76; (C #)
It is very simple to see, you don't have to know what Alpha variables. Transparency is only a kind of effectiveness
Don't abuse it.
3. How to set the location of the form on the screen
You can set the StartPosition property of the form, and vs.net generally gives you a conservative option. "
WindowsDefaultLocation "This system will be set according to the user's current computer when the system is in the Load Form.
To determine a value, you can also change it to another "center" when designing.
If you must determine the form in the design mode, you can set it first.
StartPosition is Manual, then sets the value of the x and y of the Location.
Implementation of code in runtime seems to be more concise:
Form1.Location = New Point (100, 100) (VB.NET)
Of course, you can also modify the x and y values of the Location, corresponding to the list of LEFTs and TOP properties, such as
:
Form1.Left = 200 (VB.NET)
Form1.top - = 100 (VB.NET)
Another property will also affect the form on the screen: DesktopLocation This property is mainly
You set the location of the form is very practical relative to the task bar (when you put the task bar on the top or on the left side of the screen.
In fact, the corresponding changes in Desktop Coordinates (0, 0)), you can set this not appearing in design
Properties in the property window,
Form1.Desktoplocation = new point (100,100)
The location of the form in the screen will mainly depend on the specific hardware and settings of their respective users, so conservative work
The method is to use the default "windowsdefaultlocation" or "center"; professional practice is the first
Get the system settings and then encodes the dynamic calculation and set, otherwise it is easy to find your form on the screen.
4. How to make minimization and maximize buttons are not available
Form.minimizeBox and form.maximizebox set in the formation Form.maximizeBox indicate display, False
It is not possible when it is not possible. See you by programming:
frmmaxmin.minnimizebox = false (vb.net)
frmmaxmin.maxmnimizebox = true (vb.net)
5. How to make a form don't see
I think the most direct way is that you call hide () methods to do this. But I want to provide another method.
You will get some other inspiration after you have seen it. (VB.NET)
Private const WS_EX_TOOLWINDOW AS INT32 = & H80
Private const WS_POPUP As Int32 = & H80000000
Private const ws_visible as int32 = & h10000000
Private const ws_sysmenu as INT32 = & h80000
Private const WS_maximizebox as int32 = & h10000
Protected Overrides Readonly Property CreateParams () AS System.
Windows.Forms.createParams
Get
DIM CP as System.Windows.Forms.createParams
Cp = mybase.createparams
cp.exStyle = WS_EX_TOOLWINDOW
Cp.Style = WS_POPUP or WS_VISible or WS_SYSMENU OR
WS_MAXIMIZEBOX
cp.height = 0
cp.width = 0
Return CP
END GET
End Property
It turned out to set Height and Width to 0, I think this way and hide () is called
It is different.
6. How to set the form into non-rectangle.
I think I am not the most professional approach, at least it can't reach the expectations, that is
Say it in some events will also change back to rectangles. But at least I can tell you: If you try to call the original
Win32's API setWindowrng is not good, I have tried this. Now you may need to know
Clock in the region property of the form
'// (vb.net)
Public SUB SETWINDOWREGON ()
DIM FORMPATH as system.drawing.drawing2d.graphicspath
Dim Reg As Drawing.Region
Dim Lret As Long
FormPath = new drawing2d.graphicspath ()
FormPath.Addellipse (New Rectangle (0, 0, 250, 120))
Me.Region = New Region (FormPath)
End Sub
Private sub button1_click (Byval Sender As System.Object, ByVal E
As system.eventargs) Handles Button1.click
Me.Region = Nothing
SetWindowRegion ()
End Sub
Protected Overrides Sub onResize (Byval E AS System.EventArgs)
Me.Region = Nothing
SetWindowRegion ()
End Sub7. How to make a form on the top of the screen.
This is a very practical feature, now you don't have to call other APIs, just set the TopMost property as
True is ok. For this property, it can be modified at design time and runtime. Code mode
:
Mytopform.topmost = true (vb.net)
8. How to display a form of Model and non-Model
The form of Model and Modeless will mainly depend on your application, the most is used in the display dialog. When you need
When you want to model, you call myform. Showdialog rather than Model's call myform.show,
ShowDialog has an optional parameter Ower to make you build a father and child relationship for a form. For example:
'Visual Basic
Private sub mnuabout_click (... args ...)
DIM F AS New Formption
F.ShowDialog ME
End Sub
One thing to note is that for ShowDialog, when executed, the form is displayed, but after this
The code will not execute, only after the window is closed, and it is instant, displayed for Show
The following code will be performed immediately after the body.
9. How to make a MDI form
1. Create a new Windows Application project
2. Add two forms of forms1, Form2 separately
3. Set the ISMDicontAiner property of Form1 to true. Make it a MDI main form.
4. Add a RichTextBox control in Form2 and set the Dock as: Fill
5. Drag a mainmenu to the form FORM1 in the Tools form, then create a menu
FILE | Windows | Help Three menu items, including new, exit menu items in the file; including Windows
Cascade, Horizontal, etc.
6. Set the mdilist property of the Windows menu item = true, so that each MDI sub-window will automatically
Add below the Windows menu item.
7. Double-click the New menu item, then add the following code:
Private void Menunew_click (Object Sender, System.Eventargs E)
{
Form2 newmdichild;
Newmdichild = new form2 ();
NEWMDICHILD.MDIPARENT = this;
Newmdichild.show ();
}
8. Add the following code in the menu items such as Windows Cascade:
Private void menuwindowcasca_click (Object Sender, System.
Eventargs E)
{
This.Layoutmdi (MDILAYOUT.CASCADE);
}
There is also the following common:
THIS.LAYOUTMDI (MDILAYOUT.TILEHORIZONTAL);
THIS.LAYOUTMDI (MDILAYOUT.TILEVERTICAL);
9. F5 runs.
The final version of VS.NET does not know if there will be a common template, but it creates a complete manual way.
MDI's window, which is a bit cumbersome, not as simple as the IDE mode of vs.net.
