CA_CreateObjectByClassIdEx invalid return code

[l3]

Based on the sample code for opening an excel spreadsheet, I have the function Excel_NewApp(.....). This function calls CA_CreateObjectByClassIdEx (......). The problem I am having is CA_CreateObjectByClassIdEx returns an error code of 0x80029C4A, which does not seem to be defined in the list of return codes for the function panel. What does this error indicate?

I am using LabWindows 7.0 on a windows xp machine. In addtion, the program using this software is functioning on other windows xp machines.

Thanks

Hi I3,

This error is coming from the ActiveX server.  It looks like there is a problem with Word's ActiveX server.  I think that the easiest first step might be to uninstall/reinstall Excel (or just MS Office).  Also, take a look at this post which describes rebuilding the ActiveX driver for Word from CVI.

Hope this helps,

I tried re-installing excel. However, this did not seem to fix the problem. I think I'll try re-installing all of office before rebuilding the ActiveX driver.  Do I have to rebuild the ActiveX driver for Word or Excel since my problem seems to be related to Excel?

You need to rebuild the Excel driver.

By the way, you can find a list of automation (ActiveX) error codes in this article.
