#621 Visual Studio AddPropertySheet Type Error

[Anonymous]

When trying to add a style sheet to a visual studio C++ project using pythoncom, the following error occurs

Traceback (most recent call last):
File "test.py", line 87, in <module>
proj.addPropertySheet("d:\\temp\\vs\\boost.props")
File "test.py", line 34, in addPropertySheet
sheet = conf.AddPropertySheet(file)

ret = self._oleobj_.InvokeTypes(782, LCID, 1, (9, 0), ((31, 1),),FileName
TypeError: The VARIANT type is unknown (0x0000001f)

31 is VT_LPWSTR, which is not valid in a VARIANT. This looks like a bug in the typelib. If you edit the generated file and change it to VT_BSTR (8)
does it succeed ?

Changing to VT_BSTR(8) results in a different error

Could you try passing win32com.client.VARIANT(pythoncom.VT_LPWSTR, "the string") and see if that helps?

[Anonymous]

Passing the variant as suggested results in the original error

TypeError: The VARIANT type is unknown (0x0000001f)
