Hi all...

I'm writing a very simple MP3 player as a learning exercise in various .Net technologies. The app allows the user to enter a directory name containing the audio files they want to load. I also allow the user to specify one or both of "*.mp3" or "*.wma" as the file extensions... but I can't work out how to return matching files without using the FileOpen dialog which I want to avoid.

eg: What I have now is...

dir = "F:\mp3\test"
filter = "*.mp3|*.wma"
Dim foundFiles As String()
foundFiles = Directory.GetFiles(dir, filter)

If the user selects only MP3 **OR** WMA then it works fine but if they select both (so the filter = "*.mp3|*.wma" as above) it returns nothing since the filter obviously matches no files.

So my Q is how can I get the filesystem to return me a list of files that match a filter containing multiple file types without using the FileOpen dialog?

TIA...

Mike.
