Export excel file with header

Post by **Marc** » Mon Jun 19, 2006 9:55 am

Hello David,

It seems that the source files being shipped with the current TeeChart version are slightly out of sync with the latest Library revision. Apologies for the inconvenience, we'll correct that for the next update.

I've posted the new classes to the attachments newsgroup:

news://www.steema.net/steema.public.attachments

Alternatively you can generate uptodate wrapper classes at any time in the following way:

- create a new dialog based project in mfc
- From the VC++ v6 IDE select "Project":"Add to project":"Components and Controls":"Registered ActiveX Controls" ... select "TeeChart Pro ActiveX Control v7" from the list.
- Accept with "OK" and the VC++ ClassWizard will generate all the classes related to the version of TeeChart registered. You may then re-use those class files in other projects.

Regards,
Marc Meumann

Hi, Marc,

Thanks for your reply. I can't visit the newsgroups in the company. Would you please send me the zipped file of the new classes? Thank you very much!

As for the method you mentioned to generate the classes, it is only applicable to VC++ v6, but I am using VC++.NET 2003 and it could work that way. Thanks anyway!

David

Hi David,

Of course, I've sent the files to your forums contact e-mail address.

Hi,

There is a problem with the new classes. After I replaced all of the old class files with the new ones, the project compile fails with this error message:

tchart.h(31) : error C2011: 'CTChart' : 'class' type redefinition

Then I used back the old tchar.h and and tchart.cpp, the compile passed.

Any suggestions
David

Hello David,

Please check if there are any compile tags at the beginning/end of the old TChart.h/.cpp files. You could copy those to the new header file. Those avoid redeclarations of TChart if calld from multiple source files.

ie.

#if !defined(AFX_TCHART_H__71AE5870_FEC8_405D_8C6F_9C8CE5D9EF3A__INCLUDED_)
#define AFX_TCHART_H__71AE5870_FEC8_405D_8C6F_9C8CE5D9EF3A__INCLUDED_

#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000

..... file contents.....

#endif // !defined(AFX_TCHART_H__71AE5870_FEC8_405D_8C6F_9C8CE5D9EF3A__INCLUDED_)

Hi, Marc,

Yeah, it is fixed following your advice. But do I need to check all the class files manually? I noticed there are quite a few header files with different size and I opened some and the main difference is the compile tags missing in the new files. Will they be the same in the next release?

Thank you very much!
David

Hello David,

I don't think it necessary to check all the files and would only return those tags on a 'need to' basis as I don't think they are necessary unless multiple includes are made in your code that provoke the problem (doesn't always occur).

I would expect the next update to be similar to this one, we generate the library wrappers by using the VC ClassWizard and so let it auto-generate according to its syntax rules.

Regards!
Marc
