try trimming your strWinDir

I know you need the Space(255) for the buffer into unmanaged, but maybe
adding a .Trim() after all is said and done would help.

Cut off the content of 'strWinDir' ('intRet' will contain the length of
the windows directory's path) using 'Left'.
 
I can't find the left in vb.net, so
I used the trim

arrFiles = system.IO.Directory.GetFiles (strWinDir.Trim & "\media\","*.wav")

This still gets me the exception.

If I remove the "*.wav" and substitute ""
no exception occurs, but the arrfiles array is empty.

'Trim' won't work here too. Use something like
'Strings.Left(strWinDir, intRet) & ...'.
 
If I put a literal "C:\Windows"
in the get files statement it works.

example:

arrFiles = system.IO.Directory.GetFiles ("C:\Windows" &
"\media\","*.wav")


but it doesn't like it if the first parameter is a variable
string.

worked.

What is Strings.left ?
Click to expand...

It takes the left part of a string (the 1st 'intRet' number of
characters).
