None-Resize Window

martinsalo

Hello Forum,

how can I create a fixed sized window? I have adapted the "COR_DotNetForms" example for my AddIn. I have set Minimum and Maximum Size to the same values in Size. I have set Borderstyle to FixedSingle. But the form is resizeable!?

Thanks

Martin

I have added some Winapi Code to the form. No resizing und window-maximize is disabled:

// Get Parent Window:
IntPtr ParentHandle = WinAPI_GetParent(this.Handle);

// Retrieves styles information about the window:
int GWL_STYLE = -16; // Window styles request.
int dwStyle = WinAPI_GetWindowLong(ParentHandle , GWL_STYLE);

// Set new Styles: No resize, no maximize:
int WS_SIZEBOX = 0x00040000; // No window resize
int WS_MAXIMIZEBOX = 0x00010000; // No maximize button in menu bar.
dwStyle &= ~(WS_SIZEBOX | WS_MAXIMIZEBOX);
int retval = WinAPI_SetWindowLong(ParentHandle , GWL_STYLE , (int)dwStyle);

// Set size manually:
WinAPI_SetWindowPos(ParentHandle , (IntPtr)0 , 0 , 0 , 240 , 145 , SetWindowPosFlags.IgnoreMove);
