Hi,

I'm writing an addin and I've hooked myself to the build event to be able to
execute an external program at the start of the build. In itself it works
very well. Part of the code is below.

My problem is that I'd like to be able to cancel the build while this
external process is running similar to any other build cancellation.. Which
means that I want visual.net to still process its events. To be able to do
that I've hooked myself to the BeforeCommand event of the Build.Cancel
command but as long as the external process runs the cancellation event
doesn't occurs(as the event is not processed until the end of the process)

Does anybody know what I would have to add in my loop to be able to let
visual.net handle all it's events ?

Thanks

private void OnBuildBegin(vsBuildScope scope, vsBuildAction action)
{
if (action == vsBuildAction.vsBuildActionBuild ||
 action == vsBuildAction.vsBuildActionClean ||
 action == vsBuildAction.vsBuildActionRebuildAll)
{
 // skipped unimportant stuff...

 // Execute
 System.Diagnostics.Process p = new System.Diagnostics.Process();
 p.StartInfo.FileName = m_InstallPath + "parser.exe";
 p.StartInfo.Arguments = Arguments;
 p.StartInfo.CreateNoWindow = true;
 p.StartInfo.UseShellExecute = false;
 p.StartInfo.RedirectStandardOutput = true;
 p.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
 p.Start();

 string line;
 while(!p.HasExited)
 {
  line = p.StandardOutput.ReadLine();
  DisplayOutput(line + "\n");
 }
 // Insure that we don't miss the remaining output.
 line = p.StandardOutput.ReadToEnd();
 DisplayOutput(line + "\n");
 p.WaitForExit();
}
}
