addin that tells the Visual Studio to start a program and attach to it

So I found the following:

EnvDTE.Processes procs = _applicationObject.Debugger.LocalProcesses;
EnvDTE.Process p = procs.Item(0);
p.Attach();

The trouble is procs.Item(object x) takes object as signature. So how do I iterate through all the processes in procs?

Thanks

Here is the code I came up with. The problem is that Visual Studio attaches to it - but my breakpoints are never hit. The program ends up executing to completion. I tried p.Break(true) and dte.Debugger.Break(true) - but both of them raise COM exception. It seems like breakpoints are not getting set after attach. Is there any other API I need to call to enable the break points? My break points have been pre-set in Visual Studio. I load my plugin which executes this code and it should attach to my process and hit the break points. It attaches but never hits my break points.

If I attach to my process without this plugin, it works perfectly i.e. VS stops at my breakpoints.

EnvDTE80.DTE2 dte = (EnvDTE80.DTE2)System.Runtime.InteropServices.Marshal.GetActiveObject(
"VisualStudio.DTE.8.0");
Processes procs = dte.Debugger.LocalProcesses;
bool found = false;
foreach (EnvDTE80.Process2 p in procs) {
if (p.Name != null && p.Name.Length > 0) {
string comName = p.Name;
try {
comName = Path.GetFileName(comName);
}
catch { }
if (comName.Trim().ToLower() == "myprog.exe") {
p.Attach2("Managed");
dte.Debugger.CurrentProcess = p;
found = true;
break;
}
}
}
