loading a COM object dynamically?

[giddy]

hi,

I'm using OCR in my application. Its not a feature my users can't live
without. I need office 2003+ installed.

So instead of referencing the MODI library, i want to late bind it? In
other words check which exists and then use it.

Is this even possible?!

Gideon,

Well, regardless of whether or not it is installed, you should have a
reference to the interop assembly that you are going to use to access it.
Then, when you want to check to see if the appropriate library is installed,
just try to create an instance of your class. Wrap that in a try/catch
handler. If you get an exception, then the product is not installed
properly, and your program can act accordingly.

hi Nicholas.,

Do you mean i should early bind it(add reference) ? An interop
assembly is created when i do.

So my app wont crash/throw exceptions if it doesn't find a reference?
It only will throw an exception when i create an instance of the
class? Cool.

Thanks.

Gideon
