Hmm, that's a pretty confusing condition there... I'd probably split it out into a separate function just to make it clearer. Like so:
bool IsShowInTaskbar(HWND hwnd){ if (!IsWindowVisible(hwnd)) { return false; } LONG exstyle = GetWindowLong(hwnd, GWL_EX_EXSTYLE); if ((exstyle & WS_EX_APPWINDOW) != 0) { // WS_EX_APPWINDOW windows are always in the taskbar return true; } if ((exstyle & WS_EX_TOOLWINDOW) != 0) { // WS_EX_TOOLWINDOW windows are never in the taskbar return false; } // if it's not WS_EX_APPWINDOW or WS_EX_TOOLWINDOW, then it's in the // taskbar if it's a top-level window return (GetParent(hwnd) == NULL);}
Also, I don't believe you need to check the WS_CAPTION style. I don't think that has an effect.
