Hello,
I am using a COM dll server (USBIO) from LABView. This is only a COM server and NOT an activeX control. I have successfully managed calling its methods and properties (with the activeX "Invoke node" and "Property node"). But now I have been trying to use its events call-back functions. I tried to "list events description" from the ActiveX menu. But this function doesn't list anything.
I know that this COM server can be accessed from Visual Basic (properties, methods, AND EVENTS). I have read in the forum that I probably have to write a wrapper dll to encapsulate the events call, or perhaps writing an activeX control in Visual Basic.
Do you know
- how difficult these are ?
- What are the principal steps to manage these ?
Thank you very much fo
r your reading."
