I'm having problems with the basics of windows api programming.
before you attack me i do have a book, and i did read on-line tutorials on the subject, but they are so blur.
all i need is a simple explanation on:
1. what is a Device Context ?
2. how does the SelectObject() works, what does it mean selecting an object?
3. when i want to use an object or draw something why do i need to create a compatibleDC, like so:
Code:HDC hDC, memDC; HBRUSH hBrush; hDC = GetDC(hwnd); memDC = CreateCompatibleDC(hdc); hBrush = (HBRUSH) GetStockObject(WHITE_BRUSH); SelectObject(memDC, hBrush); PatBlt(memDC, 0, 0, 100, 100, PATCOPY); BitBlt(hDC, 0, 0, 100, 100, memDC, 0, 0, SRCCOPY); ReleaseDC(hwnd, hDC); DeleteDC(memDC);
thank you very much,
