C/C++/C# Force window to be on top
提问by Jerry Coffin
Is the there a way to force anotherwindow to be on top? Notthe application's window, but anotherone, already running on the system. (Windows, C/C++/C#)
有没有办法强制另一个窗口在上面？不是应用程序的窗口，而是另一个已经在系统上运行的窗口。(Windows, C/C++/C#)

You can use the Win32 API BringWindowToTop. It takes an HWND.
您可以使用 Win32 API BringWindowToTop。它需要一个 HWND。
You could also use the Win32 API SetWindowPoswhich also allows you to do things like make the window a top-level window.
您还可以使用 Win32 API SetWindowPos，它也允许您执行诸如使窗口成为顶级窗口之类的操作。
回答by Jerry Coffin
SetWindowPos(that_window_handle, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE);
BringWindowToTopmoves the window to the top of the Z-order (for now) but does notmake it a topmost window.
BringWindowToTop将窗口的Z顺序的顶部（现在）但不能使之成为最顶层的窗口。
回答by RED SOFT ADAIR
BringWindowToTop() has no effect if you want to bring a applications window from behind (or minimized) to front. The following code does this trick reliable:
如果您想将应用程序窗口从后面（或最小化）到前面，BringWindowToTop() 不起作用。以下代码可靠地执行此技巧：
ShowWindow(hwnd, SW_MINIMIZE);
ShowWindow(hwnd, SW_RESTORE);

BOOL CALLBACK EnumWindowsProc(HWND hWnd, long lParam) {
wchar_t buff[255];
if (IsWindowVisible(hWnd)) {
GetWindowText(hWnd, (LPWSTR) buff, 254);
//wprintf(L"%s\n", buff);
wstring ws = buff;
if (ws.find(L"Firefox") != ws.npos)
{
::SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);
}
}
return TRUE;
}
int main(){
BOOL enumeratingWindowsSucceeded = ::EnumWindows( EnumWindowsProc, NULL );
}
