Set window background

[BarankinBeAMan]

How do I set dialog based window background to any other color
in run time ?
I noticed that background is set onInitialize ,
is there a way to change the color just like for other control as CEdit?

Here is how you could change the backcolor of a dialog:

HBRUSH g_hbrBackground = CreateSolidBrush(RGB(0,255,0));

case WM_CTLCOLORDLG:
      return (LON)g_hbrBackGround;
case WM_CTLCOLORSTATIC:
 {
     HDC hdcStatic = (HDC)wParam;
     SetTextColor(hdcStatic, RGB(255,255,255));
     SetBkMode(hdcStatic,TRANSPARENT);
     return (LONG)g_hbrBackground;
}
break;

Where do I insert this code in Dialog based window?
Does it have to be in window message hanling function?

LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)?

Yes.

Here is an example:

#include <windows.h>

#include "resource.h" 

HBRUSH g_hbrBackground = NULL;

BOOL CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
    switch(Message)
    {
        case WM_INITDIALOG:
            g_hbrBackground = CreateSolidBrush(RGB(0, 0, 0));

            SendMessage(hwnd, WM_SETICON, ICON_SMALL, (LPARAM)LoadIcon(NULL, 
                MAKEINTRESOURCE(IDI_APPLICATION)));
            SendMessage(hwnd, WM_SETICON, ICON_BIG, (LPARAM)LoadIcon(NULL, 
                MAKEINTRESOURCE(IDI_APPLICATION)));
        break;
        case WM_CLOSE:
            EndDialog(hwnd, 0);
        break;
        case WM_CTLCOLORDLG:    
            return (LONG)g_hbrBackground;
        case WM_CTLCOLORSTATIC:
        {
            HDC hdcStatic = (HDC)wParam;
            SetTextColor(hdcStatic, RGB(255, 255, 255));
            SetBkMode(hdcStatic, TRANSPARENT);
            return (LONG)g_hbrBackground;
        }
        break;
        case WM_COMMAND:
            switch(LOWORD(wParam))
            {
                case IDOK:
                    EndDialog(hwnd, 0);
                break;
            }
        break;
        case WM_DESTROY:
            DeleteObject(g_hbrBackground);
        break;
        default:
            return FALSE;
    }
    return TRUE;
}

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
    LPSTR lpCmdLine, int nCmdShow)
{
    return DialogBox(hInstance, MAKEINTRESOURCE(IDD_MAIN), NULL, DlgProc);
}
