    Question wM_SIZING

    WM_SIZING isn't working for me. For some reason i don't recive it while
    the window is being resized. I recive it after the drag is released, just like WM_SIZE.
    I really have no idea, why this is happening.

    I need to use this in order to limit how much can a user resize my window,
    other solutions would be welcome too.

    A window receives this message through its WindowProc function.


    WM_SIZING

    WPARAM wParam
    LPARAM lParam;
    wParam
    Specifies which edge of the window is being sized. This parameter can be one of the following values.
    WMSZ_BOTTOM - Bottom edge
    WMSZ_BOTTOMLEFT - Bottom-left corner
    WMSZ_BOTTOMRIGHT - Bottom-right corner
    WMSZ_LEFT - Left edge
    WMSZ_RIGHT - Right edge
    WMSZ_TOP - Top edge
    WMSZ_TOPLEFT - Top-left corner
    WMSZ_TOPRIGHT - Top-right corner
    lParam
    Pointer to a RECT structure with the screen coordinates of the drag rectangle. To change the size or position of
    the drag rectangle, an application must change the members of this structure.

    WM_SIZE should be send while the window is being dragged.

    At it least it does that for me.

    WM_SIZING also works just fine.

    Perhaps WM_GETMINMAXINFO would be more appropriate for this.

    I don't know how to use it, can you post an example?
    There must be a normal & easy way to limit the resizing...

    I just whipped this up in the reply field, untested.
    Code:
    WM_GETMINMAXINFO:
    {
    	MINMAXINFO * mmiStruct = (MINMAXINFO*)lParam;
    
    	POINT ptPoint;
    
    	ptPoint.x = 300;	//Minimum width of the window.
    	ptPoint.y = 300;	//Minimum height of the window.
    	mmiStruct->ptMinTrackSize = ptPoint;
    
    	ptPoint.x = GetSystemMetrics(SM_CXMAXIMIZED);	//Maximum width of the window.
    	ptPoint.y = GetSystemMetrics(SM_CYMAXIMIZED);	//Maximum height of the window.
    	mmiStruct->ptMaxTrackSize = ptPoint;
    
    	return 0;
    }

    To completly stop the user from resizing your window you can simply just use the dwStyles of WS_OVERLAPPED | WS_SYSMENU in the call to CreateWindowEx

    It Works, Thanks!!!!!!
