  1. I'm running VB6 on a Teradyne UltraFlex .Net 4.0, trying to talk to a MD MAXTC PLC. I've installed the UnCmDrv1.dll. I'm trying the following call from both my VB6 program and the "VisionCommDriveExample" provided by you. I get the following error (see attached file) to this command: 'Create new instance of the Comm Driver Dll. Set mComDriver = New UnCmDrv1.clsCommDriver basically a "Run-time error '339': Application-defined or object-defined error" Any ideas what I'm missing? Regards, Doug 399Error.docx
