Hi Paul, No, I am using Visual Basic and MI Pro 6.0 via OLE and I have not problems with this. I have another problem that you probably can help me.
I want to set Snap On/Off. The problem is that if the key pressed last time is not inside the Map, if I press the Snap it does not run. I know is because the Map (and Mapinfo) has not the focus, but is there a way to set the snap on/off despite where the last click was in the application ?
