while opening any excel files (.xls files) in MS EXCEL.EXE, I need to do
some data existence check in that xls file. How do I do this. Can anybody
shares the brief details.
i.e. The user can open any xls file in EXCEL.EXE and my addin/application
should work in back ground and look for the existence of particular type of
data (specific data pattern) then update some [m,n] cell on the xls file with
YES/ NO values etc.,

I tried developing COM Addin using C# but could not get the corresponding
event for opening the exisitng workbook.

Any help would be great and appreciated.

I am using OFFICE 2003 and Visual Studio .Net 2003 on FrameWork v1.1

thanks,
-Ram.

You need to hook the Excel.Application's WorkbookOpen event which passes the
newly-opened workbook as its argument.

Rob,

I tried by Excel COM addin which implements IDTExtensibility2 interface.
This has evnts for OnConnection, OnDisconnection, OnBeginShutDown,
OnCompletStartup, and OnUpdateAddIn events which refers the host application
(EXCEL.exe) life cycle. Afterwards I could not get hold of how to raise this
Excel.Application's WorkbookOpen event.

Is it possible for you to help with code snippet for this.

thanks in advance,
-Ram.

Your OnConnection event passes as its first argument Application As Object.
This is the instance of Excel that you're running inside. Cast this into a
variable of type excel.application and then you can hook the application's
events either by declaring the variable WithEvents (you can do that in C#,
right?) or by using delegates (if you must insist on doing things the curly
bracketted way ;-)
