in reply to "pointers" for calling a DLL

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.

UPDATE: 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" rawfile.Open (filename) Dim return_filename As String Call rawfile.GetFileName(return_filename) MsgBox return_filename

Any other clues about how I could get this to work under Win32::OLE?

thanks, chinman
