Hi Lev,

You don't really need a timer for this. You can get away with a modal child form and passing it a reference to the calling form.

I will assume that the child form is called from a button's click. I am calling your flag "lCloseThisForm":

click event:

do form child_form with Thisform
if ThisForm.lCloseThisForm = .t.
    ThisForm.Release()
endif

in the child form's init:

lParameters toCallingForm
with ThisForm
    .AddProperty( "oCallingForm")
    .oCallingForm = toCallingForm
endwith

Then, wherever it is that you determine that the parent form must be closed:

ThisForm.oCallingForm.lCloseThisForm = .t.

When the child form's released, the parent form will close itself.

Another option would be to have the child form return a value upon release (child form's Unload event will do this for you) and have the calling form act based on that value.
