- How do you differentiate between different instances of a VBX?
-
- When multiple instances of a control are created, the same HCTL value
- is always passed to the main control procedure for all messages. The
- HCTL value is used to generate events with the VBFireEvent function.
- So, without a unique HCTL value, how do I generate the events in the
- correct instance of the control?
-
- I have created a winsock VBX (with VC++ 1.5) and if multiple
- applications using the VBX are opened, all events generated within the
- VBX are passed to the last created instance.
-
- Also, are there any good references for creating VBX's, OCX's, or
- converting VBX's to OCX's?
-
- Thanks
