WM_CTLCOLORSTATIC: Try #2

[Technocrat]

Ok the fourm is all messed up. So if this gets posted more than once I am going to be pissed

I have this problem with changing the background color and text color of an edit box. It looks like it is no getting set right on the paint. If you look at the attached pic you will see.

Here is the code:

case WM_CREATE:
        {
            hBrush_Changes = CreateSolidBrush(RGB(0,0,0));
            hBrush_AppInfo = CreateSolidBrush(RGB(0,0,0));
            return DefWindowProc(hWnd, message, wParam, lParam);
        }
        case WM_CLOSE:
        {
            DeleteObject(hBrush_Changes);
            DeleteObject(hBrush_AppInfo);
            DestroyWindow(hWnd);
            m_hWnd_About = NULL;
            break;
        }

        
        case WM_CTLCOLORSTATIC:
            if ((HWND)lParam == m_hWnd_Changes)
            {
                SetTextColor((HDC)wParam, RGB(0,100,255));
                SetBkMode((HDC)wParam, TRANSPARENT);
                return (long)hBrush_Changes;
            }
            if ((HWND)lParam == m_hWnd_AppInfo)
            {
                SetTextColor((HDC)wParam, RGB(0,100,255));
                SetBkMode((HDC)wParam, TRANSPARENT);
                return (long)hBrush_AppInfo;
            }
        break;

        case WM_PAINT:
        {
            BeginPaint(hWnd,&ps);
            EndPaint(hWnd,&ps);
            break;
        } //WM_PAINT 

Any suggestions?

if your Edit control is not set to Read Only, then you need to move you code to the WM_CTLCOLOREDIT event instead of the WM_CTLCOLORSTATIC

[Technocrat]

No they are readonly

[Chris]

Juz can't anything out from your code & it seem weird 'coz i did the same thing in my application too.

Perhaps, the problem is from where you update the text in the edit control?

Well here is the rest of my code. Its not pretty because I havent finished it.

I copy all your code into a new project except those CEdit section and it work fine.

I guest the problem is not on WM_CTLCOLORSTATIC but is somewhere else.

[Technocrat]

Bah
Well if I could I would post the entire project, but it requires Novell GW to run.

Oh well I guess I will just have to keep working on the problem.
