Hi there ! I have a simple ActiveX client program (written in C) which uses LabVIEW as ActiveX server, loads the specified VI, is able to set a control value and run the VI.
When I use SetControlValue ("controlLabel", value), the corresponding control indeed is set to the specified value and, if I use polling, the VI detects that the value has changed and performs the required action. Now I want to take advantage of the event-driven capability since LabVIEW 6.1 and extended in LabVIEW 7. It is stated that "Several other event-related enhancements are present in LabVIEW 7 Express. You now can programmatically generate value change events by updating a control's value using the new Value (Signaling) property." I'd like to know if I can change the Value (Signaling) property of a control from an external C program, and if so, how. If not, I'd like to understand what is meant by "You now can programmatically generate value change events by updating a control's value using the new Value (Signaling) property." and how this is done. Thanks !
