Question

I would like to write a custom gui for a compressor.

How is it possible to run the Command Line Interface on all files added into listbox ?
Also how to display a progressbar displaying the current progress (not in % but at least which file is currently processing).

Answer 1

If you’re talking about just running a command line program, you can use System.Diagnostic.Process.

System.Diagnostics.Process p = new System.Diagnostics.Process();

p.StartInfo.FileName = @"c:\path\to\my.exe";
p.StartInfo.Arguments = @"c:\path\to\filetoCompress.file";
//event wireup

p.Exited += new EventHandler(p_exited);
p.Start();

As far as displaying progress for that, you could use the Exited event of the process to wire up to a process bar that shows the progress of number exted vs. number total.

void p_Exited(object sender, EventArgs e)
{
   //assuming you have setup this bar previously.
   pbFilesCommpressProgress.PerformStep();
}
