I am trying to build a form in a class. Everything is working ok, but now
I want to return a value from the form.
How do I get the return value passed back to the calling form ?
Here is my code:
oForm = createobject("testform")
oForm.show(1)
lcReturnMsg = oForm.cReturnMsg
The problem is the 3rd line errors out with oForm not valid because the form
has already released
So what is the trick to return a value from a form in a class ?
Typically I do something like this (untested and no error-trapping, but
enough to give the gist):
DEFINE CLASS Form1 AS Form
ModalResult = ""
PROCEDURE LaunchForm2
oForm = CREATEOBJECT("Form2",THISFORM)
oForm.Show(1)
* Do something with THISFORM.ModalResult here....
ENDPROC
ENDDEFINE
DEFINE CLASS Form2 AS Form
ReturnValue = ""
Caller = .NULL.
PROCEDURE Init
LPARAMETERS oCaller
THIS.Caller = oCaller
ENDPROC
PROCEDURE DoSomethingUseful
THIS.ReturnValue = "Foo"
ENDPROC
PROCEDURE UNLOAD
oCaller.ModalResult = THIS.ReturnValue
ENDPROC
ENDDEFINE
