   Double-buffering on dialogs
  If using WS_EX_COMPOSITED, the dialog's close button becomes unredrawable. This is the code what I use for my dialog's WM_INITDIALOG:  // Use double-buffering for window and its' childs. Prevents flickering when // redrawing window. This is only usable in Windows 5.1+.#if _WIN32_WINNT >= 0x0501 SetWindowLongPtr(hWnd, GWL_EXSTYLE, GetWindowLongPtr(hWnd, GWL_EXSTYLE) | WS_EX_COMPOSITED); #endif // _WIN32_WINNT >= 0x0501What it can be that dialog doesn't draw its' close button on hover, click etc.?[Edited by - cpp forever on June 10, 2006 2:55:45 AM]
