Example:

When you try to connect to a running Excel instance you would use ObjGet.

When there is no running Excel instance you need to use ObjCreate to start up Excel.

Please have a look at function _Excel_Open.

Thank you

How can I know If I can use ObjGet()?

I need a way to check if it exists already, so I can use ObjGet(), and if it does not exist, then I need to use ObjCreate()..

Is there a function for that?

First try ObjGet. An error indicates that there is no running instance (or some other error).

Then use ObjCreate to start up the application.

Correct, as long as you know the name of the process for sure.

What you miss is the object returned by ObjGet/ObjCreate.

I prefer not to changes methods. When working with COM I like to check the existance with a COM method.
