ocx control on VB form

I have made an OCX combo box control that saves file paths to the registry.

The way it *should* work is that the SaveSetting uses the current app name as the registry key.

Instead, the control only picks up its own app name. The control doesn't seem to have any awareness of the form it is called by etc.

How do I make the control aware of the app in which it is operating?

Within the OCX project, I want the code to be able to reference the name of the VB project in which it is being used as a component.

Maybe there's another way, but can't you pass the app name from the parent form on Form_load into a user defined property of the ocx?

I would like the control to do the job automatically; it's one of those deals where I think there should be A way, but it takes a while to find THE way.

Currently, I have a user defined property on the control in which I am manually entering the registry key; your way would automate that part, but it is quicker to type the key in than to code to automate it.

I've been looking for a good book on ActiveX / OCX controls, but I can't find any. Do you have any recommendations? :cool:

Check out Joacim Andersson's reply in this old thread:

That should be what you are looking for.

The thread deals with determining the calling program - and it works in that respect. But the value returned is for VB - not for the project in which I am using the control.

Is there a way to get the project name of the project using the OCX control? Or does that violate the rules of COM?

Thank you for your input. :)

Found this on Planet Source Code, and it works (almost) - it gives the name of the form on which the control is placed. Can you get from the ParentControls to the project name?
