[development-axapta] Arguments to an activeX method

[Thomas Jensen]

I have a problem passing a argument to a method on a third-party activex object in an Axapta form.   The prototype of the method is something like (using Visual Studio OLE/COM Object Viewer):   read(BSTR* szData)   or in the ActiveX explorer in Axapta:   read(COMVariant /*bstr*/ _szData)     In VB it can be called this way:   Dim sResult As String Activex.read(sResult)   I suppose I should pass a COMVariant object as a parameter, but how should it be initialised. I have tried:   COMVariant argument = new COMVariant(COMVariantInOut::out_retval,COMVariantType::VT_BSTR); Activex.read(argument);   But It throws a type mismatch exception.   Can anybody tell me the right way to initialize the COMVariant object or give me another solution??   Regards Thomas Jensen     Yahoo!
