direct COM call-out from Uniface to certain newer .NET based COM objects does not work. For example, it is currently not possibe to interface to a Peernet TIFF printer 9.0(http://www.peernet.com/tiff/) via the Uniface COM driver
- Customer is trying to use a Peernet virtual TIFF printer with a Uniface application and needs to interface with the 3rd party COM API. - Currently, Uniface is creating the COM signature but calling functions inside the COM object fails with a COM error. - For details see support call 1 18074
It should be possible to call .NET or C# COM objects without having to write a wrapper object to broker between these COM objects and the Uniface COM driver.
