Question

On Windows XP, how do I enumerate all the windows displayed by the system (C#)

Answer 1

+1 A:

How about this to get a list of processes that would go into the alt-tab list. (Running processes that contain a window):

using System.Diagnostics.Process; 

List <Process()> plist = new List<Process>();            

foreach (Process p in Process.GetProcesses())
{
 string title = p.MainWindowTitle;
 if (!String.IsNullOrEmpty(title))
 {
     plist.Add(p);
 }
}

In theory you got it right, but there are two mistakes in your code. First your have a syntax error when creating the list:List<Process> plist = new List<Process>();Second, in your if statement, if you only check title for null, you get all processes. if (!String.IsNullOrEmpty(title)) works.

Thanks for noticing that - i fixed the code. I guess that's what happens when you bang out code inside SO without testing first =)

Answer 2

+1 A:

I think that the blog entry by Raymond Chen pointed to in the first link gives you an idea of where you want to go. Basically, you would call EnumWindows and then apply that algorithm, except that you would take note of every window handle that is visible.

The question is a little vague, what is the purpose here (there might be a better way given more info).

I can't see it. perhaps I'm blind (or just mad). could you suggest a couple of lines of code?
