Excel Object Library(s)??

I want to read/write Excel files but I am having trouble getting started.
Using MS article 302084 as a cookbook, I try to add the reference for MS
Excel Object Library. Two versions are listed, 5 & 11. If I use 11, then then
all references to Excel fail. If I use 5, the next step in the example
fails:

Excel.Applicati on oXL = new Excel.Applicati on() ; //fails

I can do this:

Excel._ExcelApp licationClass xl = null ;
xl = new Excel._ExcelApp licationClass() ;

but I stopped there since I have no documentation, and trying to work
parallel to the example fails.

How do I get started? (VS 7.1, Office Small Business Edition 2003)

Hi,

Are you using the primary interop assemblies? Even though they are included in
Office 2003, they are not installed by default (Typical install) and are not
installed when you add a reference to a MS office type library. This could be
the problem with the 11 object library references.

I haven't done Excel automation, but I've done Outlook automation using the
interop assemblies without any problems.

Here is a MS article on the primary interop assemblies for Office 2003:
<http://msdn.microsoft. com/library/default.asp?url =/library/en-us/dv_wrcore/html/wrtskInstalling OfficePrimaryIn teropAssemblies .asp>

Hope this helps.

Best regards,

Rodger

I don't know. How could I tell?

Doing this install had no effect.

Hi - I'm able to open excel workbooks and word documents, but I can't seem to copy excel charts, named ranges, etc. to a word document. Anyone know of good reference material in this area? What little documentation I've been able to find focuses on using only one office app at a time. Thanks for your help

For most users, this new feature is actually very convenient. If you want to control the update process,...
