Hy!
I'm using some code to start an exe file instance (that will run as process) in the click event of a button.
This is the code:

Process p = null;
                
                
                    string targetDir;
                    targetDir = string.Format(@"C:\test");
                    
                    p = new Process();
                    p.StartInfo.WorkingDirectory = targetDir;
                    p.StartInfo.FileName = "test.exe";
                    p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
                    p.StartInfo.Arguments=" ";

                    
                    p.Start();
                    
                    this.Cursor = Cursors.WaitCursor;
                
                    p.WaitForExit();
                    p.Close();

My question is this: How can I modify the code to start multiple instances of this exe process - the number of instances being taken from an textbox1.text at an certain time interval taken from an textbox2.text???

Lots of programs do there own instance limitations. All the stuff my company produces for example is 1 instance only. You're not going to override the code within someone else's executable.

It's only a batch converted to exe...
Very small memory footprint, and proc usage...
I don't see the problem in wanting to run multiple instances of this exe which I created...

Create a timer, set it to the interval you want and in the event start your process. Subtract one from the count in the text box and when it reaches zero, stop the timer.

I don't think that it is that simple...
I already tried that and this resolves the interval to start process BUT the multiple instances of the same process does not work...
For some reason the application hangs...
Maybe I don't know how to set the timer in accord with starting multiple instances...I don't know...

Have a look through the source code you provided, which line do you think is the likely cause?

Try using asynchronous events, or threads. Make a thread, use ParameterizedThreadStart, give it a time to sleep until, and then fire up x number of threads. Then, in the thread, simply Join that thread for that time you gave it and once it resumes, make it run the process code.

Thanks a lot!
I finally solved the problem.
