Question Visual Inheritance & OCX

[kblair]

I have a fax viewer form that is inherited from an image viewer form. In my application, fax images are handled differently than native images but all of the viewing (rotate, zoom, etc) are the same hence my use of visual inheritance.

The image viewer control is an OCX. In the inherited form, the OCX's "native" functionality does not work. For example, in the base form, if I can draw a rectangle with the mouse to zoom to that portion of the image. In the inherited form, I get nothing. If I'm calling a method of the OCX in the base form (e.g. zoom in), it works fine. I have tried changing the Modifiers in the base form but that seems to have no effect.

Is there something I can do to allow the OCX to respond like the base form or is that just not possible with an OCX?

Thanks,

Kent

Well, lots of looks in a week but not suggestions. I guess I'll contact the developer of the OCX and see if they can shed some light on the issue.

Is anyone inheriting an OCX and getting proper behavior?
