There is simply too little information to provide any help.

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

[djh]

Thomas, tks!
for your help, how to sent the project source code to here? or sent the source code to you?
or can you give me your e-mail?

[Thomas Linder Puls]

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

[djh]

the project has a ocx file that named richeditexl.ocx,the file has 1.08MB.So,That file is too large to post here.if not the file,could you can check the project code?

[Thomas Linder Puls]

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).

[djh]

I have post the source code to support@visual-prolog.com,please help me to check them.

tks!

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.
