13. ???? How to modify the size and length width of the control form.
Mainly modify the winform's size,? Width? And height properties. They are all available in design and transportation
Modifications and settings during the time.
Form1.size? =? New? System.drawing.size (100,? 100)? (? VB.NET?)
Form1.Width? =? 100 ?? (VB.NET?)
Form1.height? - =? 20 ?? (VB.NET?)
14. How do I create a Windows® Explorer style form.
1. Create a new Windows? Application
2. Drag a TreeView control from the Toolbox window, a splitterk control, a listView control
, Set the TreeView's Dock property in the properties window, to: left; set the listView control
The DOCK property is: Fill
3:? F5? Run
15. ????? How to set the initial startup form
Whether it is C # or Visual? Basic's WinForm project you can in the Solution? Explorer window
Right click on your Project, then select Properties, select the form you start from your Project's properties page or
MAIN () method.
Some different is that the C # items in the current vs.net?beta2 will automatically generate main ()? Method, Visual
Basic.Net? You must add main () code, c # you can change Form1 to any you
You can start the form name:
????? //? (? C #?)
???????? static? void? main ()
???????? {
???????????? application.run (new? Form1 ());
????????}
16. How do I create a form with a background image
All forms in WinForm have a BackgroundImage property, which can be assigned to it.
. Ordinary forms can be done this setting in operation mode. For example
InitializeComponent () or form of constructor is added to the system:
THIS.BACKGROUNDIMAGE? =? new? Bitmap ("c: //dotnetApp//winform/tile.bmp"?);
???? For MDI's main form, you have to trouble, in the IDE form of VS.NET, when you set up
After the ismdicontainer property is True, you need to check if there is inTIALIZECOMPONENT ()
Such a code? (? C #?):
???????????? this.mdiclient1.dock? =? system.windows.Forms.dockStyle.Fill;
???????????? this.mdiclient1.name?=?"mdiclient1 ";
Or see MDICLIENT1? System.Windows.Forms in the Properties window combo box of the window.
This is the main MDI window, but I didn't find anything in the DOTNET document.
Description of System.Windows.Forms.mdiClient. Then you can in InitializeComponent ()
Or add such code in the constructor of the form (? C #?):
THIS.MDICLIENT1.BACKGROUNDIMAGE ?? =? new? bitmap ("C:
//DotnetApp//winform/tile.bmp "?)?
???? Online an ImageView example, demonstrated to join a line on the background of the MDI main form
Logo text method, so that your MDI form looks very commercial, specific you can do this:
1. ??? First in the infitIZeComponent in the vs.net? Automatically generate code, see if there is such a statement
(? C #?):
This.Controls.addRange (new? system.windows.forms.control []? {THIS.
Mdiclient1});
???? Is this MDICLIENT? (Haha)
2. ??? Establish the following two functions to display this LOGO character:
/ /? (? C #?)
???????? protected ?? void? MDI_ONPAINT? (?? Object? s, ?? System.windows.forms.
PaintevenTargs? E?)
???????? {
???????????? control? C? =? (Control) s;
???????????? Rectangle? R1? =? C.clientRectangle;
???????????? r1.width? - =? 4;
???????????? r1.height? - =? 4;
???????????? Rectangle? R2? =? R1;
???????????? r2.width? - =? 1;
???????????? r2.height? - =? 1;
???????????? font? F? =? New? Font ("tahoma",? 8);
???????????? String? Str? =? "Mywinform.net??2001?mywinform.Application?v1.
0 ";
???????????? StringFormat? Sf? =? New? StringFormat ();
???????????? sf.alignment.far;
???????????? sf.LineAlignment? =? stringAlignment.far;
???????????? e.graphics.drawstring (str,? f,? new? Solidbrush (SystemColors.controlDark,? r1,? sf);
???????????? e.graphics.drawstring (Str,? f,? new? Solidbrush (SystemColors.
ControlLight,? R2,? Sf);
????????}
???????? protected ?? void? MDI_ONRESIZE? (? Object? s?, ?? SYSTEM.EVENTARGS? E
)
???????? {
???????????? control? C? =? (Control) s;
???????????? c.INVALIDATE ();
????????}
3. ??? Add such code in the constructor of InitializationComponent () or form:
(? C #?)
???? this.controls [0] .paint? =? new? painteventhandler (? MDI_ONPAINT?)?
???? this.controls [0] .resize? =? new? Eventhandler (? MDI_ONRESIZE?)?
???????? Note that it will be added behind the InitializationComponent () or in the InitializationComponent letter
The triscontrols.addrange function is after.

In general, the entire WinForm part has always been in Hejlsberg design VJ WFC library at the WFC library, now still
No clues can prove that DOTNET is moving the WFC library, but I still believe that Delphi and VJ users will be more
It is easy to feel the design style of Hejlsberg, such as the incident being considered a few years ago.
Let the developer in the principle of "pure Java", now we can? NBSP; naturally enjoy this feature,
But on the other hand, DOTNET and JAVA or Delphi seem to be more close, you can hardly go like the MFC era.
Look from the source code to find secrets and inside.
