VBA not seeing Events from 3rd party control

[excelbobabc]

Excel 7
I have a Library that I load into Excel as a reference(.dll) The library exposes 3 controls that can be placed on a form in VBA. 2 of the controls raise events as expected(the events are raised from the library that is talking to an external device) 1 of the controls allows me to set properties and send data tto the Library, it does not raises events. The manufacturer states that Excel is blocking the Events. This seems to be true, because it all works fine in VB6 VB.net C++ and most other languages. To add another caveat, the control will not allow me to send data unless I create a reference to the original control. So the question is, does anyone know why Excel would block messages from a DLL?

Hello excelbobabc,

This is first time I have heard of Excel "blocking" events. Provided the controls in your DLL are COM compliant, there should not be any problems communicating with Excel. More likely the problem lies with the interface between the DLL and VBA. I would press the third party for more information. They may, in fact, not know why but I would ask.
