There is simply too little information to provide any help.

The dialog however reveals that something is trying to dereference a null-pointer.

If you delete the obj and exe directories, then usually a zip will become very small and can be attached here.

That file is too large to sent here.

No, I belive we also need the ocx. You can mail it all to support@visual-prolog.com, then I will have a look at it. Please also write in the mail which version of Visual Prolog you have (I ammume it is 7.4, but just to be sure).

have post the source code to support@visual-prolog.com,

Hi, djh.

I have reproduced the problem. The problem occurs inside the the ocx itself, and there does not seem to be any Visual Prolog code involved in the error. So unfortunately I cannot say what the problem is.

Have you used the component in other contexts? (I.e. do you know that it works in other contexts).

I tried using the component in a Visual Basic Form, it failed with an exception already in the design phase. But considering my Visual Basic skills I don't think we can conclude anything based on that.
