Hello. I've had a couple problems with using AX7 in Visual Studio .NET 2003(VC++). Firstly, after I insert the ActiveX control in the resource editor, if I go to the "Series" tab, I get an access violation:

Access violation at address 0F506804 in module 'TeeChart7.ocx'. Read of address 0000001C.


Secondly, I have the ActiveX control in a CAxDialogImpl<> class, and for some reason, the window isn't being destroyed properly-- only when the Teechart activeX control is on it(other activex controls work fine).

Any ideas?

Thanks.

Hi Derek,

does this happens using the latest TeeChart Pro ActiveX v7.06 (available on our web site) ?
I've test it here and it seems to work fine. If you still having problems with the latest version, please post a simple example into the news://www.steema.net/steema.public.attachments newsgroup with the steps we should do to reproduce them.

I downloaded the version posted in the Client Access area right before posting, so it seemed to happen with that. I didn't restart VS.NET 2003, nor reboot, so I'm not sure if that would affect it...

I'm considering using the IDispatch interface(with a CDispatchPtr class I use to make things easy) and saving graphs to temporary files(or possibly streaming it). This way I can offer graph creation for my product through the product's API. This would make the two problems above a non-issue to me. I wrote a prototype and it seems to work fine, so my only concern going forward would be any potential performance problems using this method, which I'll have to address when I get to that.

Thanks.
