>>Sometimes, when the following code is run, the object GRID1 has not been created yet. Which is OK, but I get the error 'ActiveControl Grid1 does not exist', basically.

>>IF UPPER(THISFORM.ACTIVECONTROL.NAME) = 'GRID1'
>> THISFORM.ACTIVECONTROL.COLUMN3.TEXT1.KEYPRESS(134,0)
>>ELSE
>> THISFORM.ACTIVECONTROL.KEYPRESS(134,0)
>>ENDIF

>>This code is in a timer, and runs often, so once in awhile 'GRID1' is not created just yet and I get the error.

>>What is the best way to prevent the error? Is there a way to check to see if the object exists before I go on with this code?
