object.visible from menu

[Shane1961]

Hi all.
I am trying to make visible a container within a form, from a menu.
Thisform.object.visible-.t. does not work.
Any help please.

In VFP, the menu is not an object contained in the form.
For this reason you can't use Thisform.

You have multiple choices. I believe the following list is not exhaustive.
- you can launch the form using the Name clause
do form whatever name variablename
- you can use _screen.activeform (not always)
- you can query _screen.forms
- you can store the form reference into a public variable, or a property of a public (variable) object
- you can store the form reference into a custom property of _screen
- you can pass form's reference to the menu / menu item, if the menu is defined inside a method of the form, like :
local ofrm
ofrm = ThisForm
...
on selection whatever... do myprocedure with ofrm

I would favour Vilhelm-Ion's first option. Use the NAME clause to get an object reference to the form; and then keep that reference in scope, for example in a public variable.

When launching the form:

[tt]PUBLIC goMyForm
DO FORM MyForm NAME goMyForm[/tt]

Then, in your menu code:
[tt]
goMyForm.MyObject.Visible = .T.[/tt]

Using public variables is not the ideal way of keeping a variable in scope, but I used it in this example for the sake of simplicity.

Thank you Vilhelm-Ion and MikeLewis.
I decided on DO FORM with MODAL as it is essentially a utility form that will not be accessed often.
One less Container. The information you provided will be useful in the future i'm sure!
Thanks again.
Shane.
