Hello all,
This is my first post and I am counting on the experience of all of you to get some help :)
I am working on a C# project and my program has to start different other applications, one by one. When an application finishes it's execution, I want to popup a message box and some other things that are not important. The applications are called from within a thread with a process, and I use an EventHandler to be called after the process finishes, just like some sort of callback function.
This works if the application I call does not call itself other applications. If so, the EventHandler that is called after the thread exits is called prematurely. More precise, I have this problem with an installer that is built with InstallShield. After the progress bar that initializes that installation, the "doneThread" EventHandler is called.
I want "doneThread" to be called when the installation finishes, not after the progress bar and installation initialization is complete.
I hope I make myself clear.. Can anyone help me on this topic?
private string commandName;
private void Begin()
{
StartProcess("C:\dummy_app.exe");
}
....
public bool StartProcess(string FileName)
{
try
{
commandName = FileName;
myThread = new Thread(this.threadWork);
myThread.Start();
return true;
}
catch (Exception)
{
MessageBox.Show("BlaBla");
return false;
}
}
private void threadWork()
{
EventHandler eh = new EventHandler(doneThread);
try
{
Process p = Process.Start(commandName);
p.WaitForExit();
}
catch (Exception)
{
MessageBox.Show();
}
try
{
//invoke doneThread when installer exits
// this is where I do my post-exit things
this.Invoke(eh);
}
catch (Exception)
{
}
}
private void doneThread(object sender, EventArgs e)
{
...
// unimportant
}Thanks a lot for reading it all to this point :)
