variable uses automation type not supported in visual basic

Hi Guys,

I've got custom faceplate for few objects communicating via OPC and whenever the faceplate is called on any station I get error as below:

Variable uses automation type not supported in visual basic in "Object Name':Faceplate::Object1_OnDataChange

The type of variable used on faceplate is VT_BOOL, I1,I4. Please help for the solution.

Thanks!

I'm uncertain about VT_I1

Type conversion can be made with Property Translation (hopefully it can read VT_I1 and expose it as eg VT_I4
