How to get handle of all the windows which are open ?

Question

Hi ,
I want to get the handle of all the windows open in the taskbar. I used 'GetForegroundWindow()'. but it shows the handle of the desktop window only.
Does any one can help

Thanks and regards

I suspect Anez means not just windows belonging to the current application but any other running application as well. The following code will get the handle of the main window for every process with a UI (i.e. a non-zero handle) running on the local machine. This isn't quite the same as what you asked for but it may suffice, depending on what you want to do: using System; using System.Diagnostics; class Program { static void Main() { Process[] procs = Process.GetProcesses(); IntPtr hWnd; foreach(Process proc in procs) { if ((hWnd = proc.MainWindowHandle) != IntPtr.Zero) { Console.WriteLine("{0} : {1}", proc.ProcessName, hWnd); } } } }

Please see Automating programs using C# . I have sample code there that uses EnumWindows . You don't need most of that sample, though. You will need: [DllImport("user32.dll")] private static extern int EnumWindows(EnumWindowsProc ewp, int lParam); public delegate bool EnumWindowsProc(int hWnd, int lParam); public static bool MyEWP(int hwnd, int lparam) { // your processing return true; } Then use it as: EnumWindowsCB cb = new EnumWindowsCB(MyEWP); EnumWindows(cb, lParam);
