Visual Basic Save - Type Mismatch

Hi,

I have a SolidWorks macro that saves filetypes from a part drawing, ie. with the drawing open, you select the filetypes to save, and the macro opens the model and saves the files.

I am trying to make a DLL using Visual Basic, and have copied across the macro to Visual Basic 2005 Express.

When I run the macro, it creates a 'Type Mismatch' error when it runs the segment of code that saves the filetype.

The segment of code looks like:

If WantParasolid.Checked = True Then 'Save off Parasolid File bRet = swDrawModel.SaveAs4("C:\fred.x_t", _ swSaveAsCurrentVersion, _ swSaveAsOptions_Silent, _ nErrors, _ nWarnings) End If

Earlier the declarations were:

Dim iSwApp As SldWorks.SldWorks Dim iSwModel As SldWorks.ModelDoc2 Dim swDrawModel As Object

Dim bRet As Boolean Dim swSaveAsCurrentVersion As Long Dim swSaveAsOptions_Silent As Long Dim nErrors As Long Dim nWarnings As Long

swDrawModel = iSwApp.OpenDoc6(sFullFilePath, DocType, 0, "", nErrors, nWarnings) swDrawModel = iSwApp.ActivateDoc(ModelName)

Can anyone help?

Thanks
