is there something similar to findfirst findnext. 

this is what i was looking for. as my background is basically C++ & VC++

But asp .net is very simple only a few lines of code will do the trick. 

here is the sample code 

' --- Directory Example ----
Dim files() as String = Directory.GetFiles(directoryPath[, optionalWildCard])

' --- DirectoryInfo Example ----
Dim myDir as DirectoryInfo = New DirectoryInfo(directoryPath)
Dim fileInfos() as FileInfo = myDir.GetFiles([optionalWildCard])
