Event in ActiveX or dll when call it in TestStand

[yangyang-rexxar]

Hi

I have a problem with ActiveX or dll build in event when call it in TestStand.

I have a VC++ code in which there is a Com port event and I deal with it in the code, then I build a dll an export some interface functions, the event and event handler is unknow from the outside, but I want to use TestStand to call this dll and I do not know whether the event can load to memory correctly and monitor the event during the whole process. In every TestStand step, is TestStand free the step content when this step is finished? or it is always residing in the memory.

I consider to build it as a dll or an ActiveX
