I think in the current stable version (1.1.2.885) there is a bug in Code Input Helper.
After entering any two of the characters suddenly pops up a dialog box with the message "Interface not supported".
In the previous stable version (1.1.1.849) this bug did not occur.
(I am using Delphi XE.)

Oh, severe problem, could you download our Debug version of CnWizards to help us to investigate this problem?

http://www.cnpack.org/download/d ... 1.1.2.886_Debug.exe

After installed it, please re-produce this problem and save the output in CnDebugViewer to xml file and send to us? master@cnpack.org

If cndebugviewer not started, please run it manually and re-produce this problem.

Done

Get it. From the trace I get some information about the calling stack, but no obvious clue to locate the root cause of this exception.

Is there a 'Detail' button in the Error Dialog of "Interface not Supported"? If yes, just press it and copy all the stack trace to master@cnpack.org again? thanks.

Unfortunately, there is no such button.
Is there any other way to find out the cause of the bug?
I would be very happy to help.

Oh, seems not IDE exception dialog but a windows system dialog. Could you provide a snapshot about it? also email to me, thanks.

There is the same issue with the 1.1.2.887

Just checked previous builds.
The issue first occurred in build 875 and is observed in all subsequent builds.

Oh, I'll check the difference between 875 and before.

875 use Delphi's CodeTemplateAPI to obtain Tempalte elements from Editor in Input Helper. Now I do some protection in 888 nightly-build version but not so sure.

Could you download the latest one to test it?

I don't know what the CodeTemplateAPI is, but 888 works fine with my XE!
Thank you very much for your excellent work!

OK, Just Fixed.

Thanks for your help!
