check to see if object exists

[KDavie]

I am trying to figure out a way to find if an object exists on a form. If it does I want it to remove it, otherwise I don't want it to do anything.

Here's my psuedo code:

If grdNotes exists then
ThisForm.RemoveObject("grdNotes")
Else
Endif

Any suggestions?

Thanks,

-Kevin

I figured out a way to accomplish my goal. I added a local variable name lcOldError, saved the current error handler, disabled error handling, removed the object, then restored the error handler back.

Here is my code:

lcOldError = ON("ERROR") && Save the error handler

ON ERROR * && Disable the current error handler
_Screen.ActiveForm.RemoveObject("grdNotes")
ON ERROR &lcOldError && Replace error handler

I'm not sure if this is a good practice or not, but it works.

Try pemstatus()

Darrell

i.e.
* In some form method:
[tt]
if pemstatus(this,"grdNotes",5)
this.removeobject("grdNotes")
endif
[/tt]

Alternatively

[COLOR=blue]WITH THISFORM
[tab]IF VARTYPE(.grdNotes) = [O]
[tab][tab].RemoveObject([grdNotes])
[tab]ENDI
ENDW[/color]
