HI

I am writing some code to convert powerpoint file to other format.
I get runtime error when the office is not activated.
How can I detect if Powerpoint( MS Office) is activated from code?

Thanks

Can't you simply trap the error when it occurs?

y, you are right. This can be a solution.

On another hand, if can know the activation info, I can pop up more
detail to the user about why it fails.

Understood.

I don't have an unactivated copy to test with. If you do, you might
have a look in the registry for differences between it and the registry
on an computer where Office has been activated.

Or better yet:

Export the registry of an unactivated computer
Activate office
Export the registry again

Compare the two exported files for differences.

Or another idea:

Force the situation to occur, trap the error number and google it.  If
you find that the error number is specific to an unactivated copy of
Office, you have a solution.

Or another:

You could write a small text file to the user's temp folder then delete
it.  If you encounter no errors there, then you know that you have
permissions sufficient for the next step:

Create a new windowless presentation in PPT, save it to the user's temp
folder.  If it errors, it's not 100% certain to be an activation issue,
but the odds are very very good.
