1.4 How can I find all programs with a GUI (not just arbitrary windows) that are running on my local machine? |
You could use EnumWindows with p/Invoke, but using the static Process.GetProcesses() found in the System.Diagnostics namespace will avoid the interop overhead. |
| [C#]
|
| Using System.Diagnostics;
|
| ...
|
| foreach ( Process p in Process.GetProcesses(System.Environment.MachineName) )
|
| {
|
| if( p.MainWindowHandle != IntPtr.Zero)
|
| {
|
| //this is a GUI app
|
| Console.WriteLine( p ); // string s = p.ToString();
|
| }
|
| }
|
|
|
| [VB.NET]
|
| Imports System.Diagnostics
|
| ...
|
| Dim p As Process
|
| For Each p In Process.GetProcesses(System.Environment.MachineName)
|
| If p.MainWindowHandle <> IntPtr.Zero Then
|
| 'this is a GUI app
|
| Console.WriteLine(p) ' string s = p.ToString();
|
| End If
|
| Next p
|
There is one potential problem on Windows 98. If a process was started with ProcessStartInfo.UseShellExecute set to true, this MainWindowHandle is not available. |
