Hi

I have a VB.net Excel Add-in that populates Excel with data pulled from a SQL database.
This can run into hundreds of thousands of rows so I need the user to be able to stop
it if they want to. What is the best way to do this. Can I use a button with code behind it?

Thanks

you need to have a condition in the code which populates the excel with the data.
assume you have a loop which iterates the DB rows and build the excel sheet.
have a global variable called stopProcessing As Boolean, set it to False
in your button click event set this variable to True
and inside the loop have some kind of condition:

While

If stopProcessing = True Then

'this is for next time you run the population
stopProcessing = False

 Break
End IF

End While
