Parameters wrong

I'm hardly an expert, but a simple test to/from VDPROJ revealed a gaping error:

The function:
static void ConvertXmlVDProj(string vdrpojFile, string xmlFile)

should be:
static void ConvertXmlVDProj(string xmlFile, string vdrpojFile)

(Note the parameter order, which in the correction matches what the calling routine has, and NOW this doesn't trash the XML file)
