I tried to unregister the toolbar OCX - no error on un-registerng. But my VFP 9 app that uses this OCX still works. So, I can't test a condition when the OCX is not registered.

So, my question is, will TRY CATCH around the line that instantiates this toolbar show the error in CATCH?

My line of code is as follows (including the TRY CATCH that I am thinking of adding:

TRY
    oApp.oToolBar = createobject( 'application_list_bar', cParameter1, cParameter2 ) 	
CATCH to oError
   Messagebox("Problem loading the list bar.  Error: " + oError.message )
ENDTRY

Note that currently I don't have the TRY/CATCH but before I add it, I want to be sure that I won't break something.

TIA
