Question

How is it possible to run a command line app on all checked items in a checkedlistbox ?

I added my files to the listbox with this code:

  private void button2_Click(object sender, EventArgs e)
  {
      var filters = "*.avi|*.mkv";
      odd.ShowNewFolderButton = false;
      if (odd.ShowDialog() == DialogResult.OK)
      {
          string folderName = odd.SelectedPath;
          string[] files = Directory.GetFiles(folderName, "*.*", SearchOption.AllDirectories);

          foreach (string file in files) checkedListBox1.Items.Add(file, CheckState.Checked);
      }
  }

Now i want to that x264.exe with parameters process (convert) all (checked) items added to the listbox

I’m not sure to have fully understood your question but if you want to run a command for each checked element in a checkedlistbox you can use a for each loop through all the checked item :

foreach(object itemChecked in checkedListBox1.CheckedItems) {
Process.Start("someapp.exe");
}
