Process Hanging

[Guest]

Hello ,

I am developping a program for Win98 plateform, and I am stucking with a
problem, hope you can help me.

I have a program running 2 process :
- One process running the Xcopy.exe
- When the first process is finished, it runs another Exe process (HHC.exe)

The code is below:

// Xcopy.exe process to copy directory 1 to 2
compiler.StartInfo.FileName = "Xcopy.exe";
compiler.StartInfo.Arguments = Dir1 + Dir2 + " " + "/S /Y";
compiler.StartInfo.UseShellExecute = false;
compiler.StartInfo.CreateNoWindow = true;
compiler.Start();

while (!compiler.HasExited)
{
Application.DoEvents();
{

// Process 2: Recompilation the new CHM with Hhc.exe external command
compiler.StartInfo.FileName = Dir 2 + "\\" + "hhc.exe";
compiler.StartInfo.Arguments = Dir2 + "\\" + "Help.hhp";
compiler.StartInfo.UseShellExecute = false;
compiler.StartInfo.CreateNoWindow = true;
compiler.Start();

while (!compiler.HasExited)
{
Application.DoEvents();
}

That's a very expensive way of waiting for the process to finish - it's
basically tight-looping. It would be better to spin off a new thread
(or threadpool task) to wait for the process to finish, and then call
Invoke on your form to let the UI thread know that the process has
finished.
