When I try that:
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "License files (*.lic)|*.lic";
if (ofd.ShowDialog() == DialogResult.OK)
{
string path = ofd.FileName;
}
With just two files in the folder "dimchain.lic" and "DMLog.licence.txt" i can see the first, but not the second in the files list. If I type 'd' I can see - and select - both files in the pop-out list, but I cannot see "DMLog.licence.txt" in teh files list at all.
What am I doing differently from you?
