ok, maybe we're getting somewhere, but
my $filename = Variant(VT_BSTR|VT_BYREF, VT_NULL);
is returning "1" for $filename when it was returning "0" before.
I don't know if this helps but, I tested this out in VB (I know, I know, yuk...). In order to get this library to work, I had to use the "Call" function on the GetFileName method. Here's the VB code.
Dim rawfile As XrawFile
Set rawfile = New XrawFile
filename = "C:\Program Files\ProMassXcali\TestData\oligos\oligo01.raw"
Dim return_filename As String
Any other clues about how I could get this to work under Win32::OLE?
