I am trying to migrate an application from powerbuilder 7.0 LOL
We used the mscomm32.ocx to communicate with a PLC via the Serial Port.
The client isn't looking to make any major changes (like communicate via TCP)
I have registered the OCX and can select it when I choose insert control/ole.
But then I get the error Insertion of OLE object failed. license file required. I don't understand this. Microsoft doesn't require a license to use this control that I know of.
Thanks
Judy

The active x has a oncomm event that is triggered when there is data. I don't think this method would handle this.
Second, do you have any reference on what the command codes are?
I think I am going to look around for a 3rd party Serial Port ActiveX
Thanks
