Set window background

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?:mad: :mad:

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

PHP Code:

---

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)?


:confused:

Yes.

Here is an example:

PHP Code:

---

#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);
}
