Drawing Text :) :confused: :)

[ZanM]

• Win32 API I need help on
• TextOut (not really but it applies)
• SetBkColor //doesn't work
• SetTextColor //doesn't work

ok i am making a cheap old api spy to help myself learn about strings and pointers and so on and I want to do TextOut with a Black Background Rect and a White Text face and i try doing it like so

    COLORREF cBack, cTxt;
    char txtOut = "Some Text";
    cBack = RGB(0, 0, 0);
    cTxt = RGB(255, 255, 255);
    
    SetBkColor(GetDC(hwnd), cBack);
    SetTextColor(GetDC(hwnd), cTxt);

    TextOut(GetDC(hwnd), 5, 5, txtOut, strlen(txtOut));

And basicly my window gets Text on it but it is not formated with the color values i used it is using the default.

so what is the problem? I thought it might be that be the COLORREF coming up bad but i used FillRect to flash my windw RGB and it works, so any ideas?

Thanks

I think you can only change the backcolor and textcolor this way when you have created a dialogbox.
If you have dialogbox then this code should work:

HBRUSH cBack;
    COLORREF cTxt;
    char *txtOut = "Some Text";
    cBack = (HBRUSH)CreateSolidBrush(RGB(255, 255, 0));
    cTxt = RGB(255, 255, 255);
    
    switch(Message)
    {
    case WM_CTLCOLORDLG:
        
        SetBkMode(GetDC(hwnd), TRANSPARENT);
        SetTextColor(GetDC(hwnd), cTxt);
               
        return (LONG)cBack;
    case WM_PAINT:
        
        TextOut(GetDC(hwnd), 5, 5, txtOut, strlen(txtOut));

No, it's just that you need the same dc for setting the colors and drawing, but you requested a new one for each thing.

COLORREF cBack, cTxt;
    char* txtOut = "Some Text";  // typo here
    cBack = RGB(0, 0, 0);
    cTxt = RGB(255, 255, 255);
    HDC hdc = GetDC(hwnd);

    SetBkColor(hdc, cBack);
    SetTextColor(hdc, cTxt);

    TextOut(hdc, 5, 5, txtOut, strlen(txtOut));

    ReleaseDC(hdc);   // you should always call that
