Hi -


I am working on migrating a FPW 2.6 application to VFp. I am very new at VFP.

I am trying to create a form that would return a value that the user inputs
into a text box.

Myform window type property is set to Modal.

Do form' Myform.scx' to cUserValue

In the form, I have a Text box. 'Text1'. The user enters a value into this text
box. In the valid event of the text box I have

:Text1.valid:

lretval=This.value

In the unload event of the form, I have the following line of code.

*form unload()
Return lretval.

This does not work. When I look at the trace window, it runs into an error at
the line 'Return lretval

For whatever reason the 'lretval' is not visible at the form unload() event.

What am I dong wrong? I am ready to tear my hair out. The only way I could
make this work is by declaring lretavl as a Public variable in the 'Init' event
of the form. But I am sure that is not the right way of doing this. Can someone
explain to em what am I doing wrong.?

Thanks in advance.

In Vfp variables' scope ends together with the current method/
procedure by default (which makes sense because of the OOP
encapsulation concept).
You can use a custom property instead - e.g in the Vfp IDE
menu -> Form -> New Property, then you can bind it to your
textbox by typing "Thisform.YourNewProperty" (w/o quotes)
in the textbox.ControlSource property.
