如何禁止窗体的重绘???
下面是C++代码,但是不知道如何在c#下使用。。。
禁止窗体重绘:
SendMessage(hWnd, WM_SETREDRAW, FALSE, 0L);
允许窗体重绘:
SendMessage(hWnd, WM_SETREDRAW, TRUE, 0L);

一样的。
C#申明下API函数。然后就可以用了。

[DllImport( "USER32.DLL ", CharSet=CharSet.Auto, SetLastError=true)]
public static extern bool SendMessage(
IntPtr hWnd, // handle to destination window
int Msg, // message
int wParam, // first message parameter
[MarshalAs(UnmanagedType.LPTStr)]StringBuilder lParam // second message parameter
);
const int WM_GETTEXT =0x000B;
const int FALSE = 0x0000;
const int TRUE = 0x0001;
SendMessage((IntPtr)this.Handle,WM_SETREDRAW,FALSE,0);

- C# code
[DllImport( "USER32.DLL ", CharSet=CharSet.Auto, SetLastError=true)] public static extern bool SendMessage( IntPtr hWnd, // handle to destination window int Msg, // message int wParam // first message parameter ); const int WM_GETTEXT =0x000B; const int FALSE = 0x0000;const int TRUE = 0x0001;SendMessage((IntPtr)this.Handle,WM_SETREDRAW,FALSE,0);
