Cycle through Configurations?

I have a program that will cycle through a given directory and create drawings for all parts in that given directory.  I am wondering if anyone can help me modify that to cycle through configurations instead of cycling through a directory.  I am a beginner programmer who has learned by seeing other codes and then modifying mine with bits and pieces of other stuff, but I haven't found anything on configurations.  I can manually enter the configuration name and get that to save as a drawing, but I have to do drawings for thousands of parts and don't want to manually enter thousands of configuration names.

Here is the code that I have that looks into the directory to get the parts.

Dim MyDir As New DirectoryInfo("C:\Documents and Settings\user\Desktop\test")

If MyDir.Exists Then

Dim MyFile As FileInfo = Nothing

Dim AllParts() As FileInfo

AllParts = MyDir.GetFiles(

"*.sldprt")

For Each MyFile In AllParts

Dim errors As Integer = 0

Dim warnings As Integer = 0

'open the part

swPart = swApp.OpenDoc6(MyFile.FullName, swDocumentTypes_e.swDocPART, swOpenDocOptions_e.swOpenDocOptions_Silent,

"", errors, warnings)

'create drawing

swDoc = swApp.NewDocument(

"C:\Documents and Settings\All Users\Application Data\SolidWorks\SolidWorks 2009\t" & _

"emplates\Drawing.drwdot", 2, 0.2794, 0.4318)
