How do you get a form to display that has been saved as a class 1

[jrumbaug]

I am using FVP8. I am visually creating my second user defined class. It is a form.

I can create the object with :
oForm = CreatObject('MyForm')

I can add values to it with:
oForm.MyItems.value = "MyInfo"

But I can't figure out how to make the form appear. It has NOT worked to say:
DO FORM oForm

Thanks in advance

try

 oForm = [blue]CreatObject[/blue]('MyForm')
oForm.[blue]show[/blue](1)  [green]&& Or 0[/green]

Hi Jim,

in fact every visual class is created invisible by CreateObject(), disregarding the .Visible Property set in the class. This is done to be able to change some properties regarding position and size etc. before showing the form,control etc.

In fact you could also show the form with oForm.visible=.t., but it's recommended to use the .Show()-Method of a form.

Bye, Olaf.

As a follow up to your suggestion:

"In fact you could also show the form with oForm.visible=.t., "

Could the "form" be disabled with :
oForm.visible=.f.

and later recalled with :
oForm.visible=.t.

The point is I would not want a form that was invisible but capable of responding to user clicks. In the future I may have a need to suspend a form and then restore without re-creating the form and it's content.

[blue]Visible[/blue] = .f. does not mean if the user clicks around he may find it and click something by mistake, it means not visible as if it did not exist. [blue]Show()[/blue] and [blue]Hide()[/blue] will acheive the same.

To clarify a little further, a form that isn't visible can never have focus, so it can't receive UI events (mouse events or keystrokes), but it does exist. If it has a timer that is enabled, that timer can fire (causing stuff to happen), and after making a form visible, then invisible, the form can be recalled with myForm.Visible=.t. again. This technique can be used to create a particular form once, and make it visible very quickly each time you need the user to see (and use) it.

Thank you Bill.
I plan on trying to use the VISIBLE=.F. with a class form I am developing. It will be pop-up list class. I was wondering how people got a return value from a form object. I knew how to get a return from a form, but if the form was an object, not called like a form, I was not sure how to get the value returned. By setting VISIBLE=.F., I can return to the calling program and still read the VALUE of the list-form object, since I am not releasing the object imediatley after the selection from the list.

Thanks to everyone.

Hi Jim,

I encountered the same trouble with returning a value from a form instantiated through CREATEOBJECT() or NEWOBJECT() ( I now use NEWOBJECT almost exclusively).

The way I did it was to have a property on my application object, FormResult, which any form which is closing could set, simply by "oApp.FormResult = whatever"... so as code that just created a modal form, and showed it through loModalForm.Show(1), could just check oApp.FormResult on the next line.
