>>Forget variables, etc. You can only have 1 top-level form in your app so use the following code to get an object reference to your TLF:

>>LOCAL loForm, loRetObj
>>loRetObj = NULL
>>FOR EACH loForm IN _SCREEN.FORMS
>>    IF loForm.SHOWWINDOW = 2
>>       loRetObj = loForm
>>       EXIT
>>    ENDIF
>>ENDFOR
>>RETURN loRetObj
>>

> loForm.Release()
> ENDIF

>So the toolbar desapears but the main form is stil there completelly unaccessible. My question is how to release top form from a toolbar.

I make sure all other child forms are closed first. I then issue a CLEAR EVENTS, release any global application objects, then release the TLF.
