Cant put a wait on external application?

[FLX]

Hello all,

I have problems letting this application wait. I tried everything in my knowledge.
Here is the code:

                    System.Diagnostics.Process procdemux = new System.Diagnostics.Process();
                    procdemux.StartInfo.UseShellExecute = true;
                    procdemux.StartInfo.CreateNoWindow = false;
                    procdemux.StartInfo.RedirectStandardOutput = false;
                    procdemux.StartInfo.FileName = currentPath + "\\res\\demux.bat";
                    procdemux.Start();
                    procdemux.WaitForExit(3000);
                    procdemux.Close();
 

this code follows it up:

            System.Diagnostics.Process procencode = new System.Diagnostics.Process();
            procencode.StartInfo.UseShellExecute = true;
            procencode.StartInfo.CreateNoWindow = false;
            procencode.StartInfo.RedirectStandardOutput = false;
            procencode.StartInfo.FileName = currentPath + "\\res\\encode.bat";
            procencode.Start();
            procencode.WaitForExit(3000);
            procencode.Close(); 
 

Can someone please help me?

Thanks in advance!

Regards,

Dennis

You can put a thread.sleep(#) in the loop to lessen the CPU load of sitting there just looping. Something like 100, or 250, shouldnt be too noticable.

Here's another idea:

Do a while loop in which you check to see that the process you started is still running. If not, break out of the loop and continue on else loop again.
This way you don't have to guess how long it will take.

The Process class has all you need for this.

I fooled around with the process.HasExit ed but the problem exists that the program might just sit there doing nothing. Its threadstate gets stuck at unknown, wait, or something else. What's it doing? Waiting for user input? Printing? Done? Its a tough issue to take up depending on the program you are using.
