ObjCreate() vs ObjGet()

[Zohar 2]

Hi

 

When shuld I use ObjCreate() and when should I use ObjGet()?

 

Thank you

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.

[Zohar 2]

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?

[guinness 1,455]

water told you to look at _Excel_Open().

[water 1,805]

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

Then use ObjCreate to start up the application.

Thank you

I imagine ProcessExists would be just as effective.

[water 1,805]

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.

[Zohar 2]

I understand.

Thank you water and JohnOne
