Convert all files in directory .WAV to .MP3

Question

See more:

There is a article in here that has a class that puts a wrapper around "Lame.exe" so you can use Lame to convert .wav files to .mp3. It works great, but I cannot seem to get it to loop through a directory and convert all files in that directory. Does anyone know how to do it with this method, or have another way of doing it?

The write a loop that goes through all the separate files in the directory and convert them one by one:

The example code is in C# but you could easily convert it to VB.

Thanks! I am looking through it now. Sorry, I am new at software development and have not worked with recursion that much. But it looks like this may be what i need.(if i can figure out how to code it).

This could perhaps make it easyer for you:

Ok, so I have it going through the folder and getting each folder name. I am using LameSHell from Qualtar. I guess with Lame, you have to loop through it with a DO LOOP. Because when I do just a FOR EACH, it just converts the first file. When I do a DO UNTIL, it goes through but hangs up the program. Maybe you can take a look at my code?

Private Sub btnConvert_Click(sender As System.Object, e As System.EventArgs) Handles btnConvert.Click
Dim cNumber As ObjectModel.ReadOnlyCollection(Of String) = My.Computer.FileSystem.GetFiles("C:\Temp")
Dim count As Integer = CInt(cNumber.Count)
Dim index As Integer = 1
Dim c As Integer = 0
Dim oPath = "C:\Temp\"
Dim dInfo As New DirectoryInfo(oPath)
Dim fArr As FileInfo() = dInfo.GetFiles()
Dim fri As FileInfo

Do
For Each fri In fArr
index += 1
Dim sfname = GetFileName(oPath + fri.Name)
ConvertFiles(oPath + sfname + ".wav", "C:\_ConvertedFiles\" + sfname + ".mp3")
lblConverted.Text = c + 1
Next fri
Loop Until index = count

I figured it out. I noticed that I was NOT starting a new instance of the converter in my converter function.
