How can I tell if an object (grid) is in use? 1

[Kflasph]

I have a form that uses pageframes. On one of the pageframes depending on the users selection, I add a class grid. In the refreshing of the data, I release the form but sometime the grid has not been added so I get an error.
How can I tell if my grid is in use?

Thanks in advance,
Kflasph

The easiest way around this would be to put a TRY ... CATCH around the code releasing the grid.

I am running VFP 6 so I can't use Try / Catch.

Thanks anyway!

When you say "in use", do you mean you want to know if the grid exists on the form? If so, then you need something like this:

IF TYPE("MyForm.MyPageFrame.Page1.MyGrid") = "O"
* grid exists
ENDIF
