>>I have been trying unsuccessfully to get a return value from a form created with createobject(""). An example of what I am trying to do: display a form and allow the user to select or enter a value from then return the value selected. This is a no brainer with a standard form but I have been trying it with a form object created from a class library and cannot figure how to get the value back to the calling program.

I have tried modeless forms and can't seem to get control back to the calling program. If I use properties in a modal form the property is destroyed prior to returning to the calling program. I have finally sunk to creating a global variable prior to creating the form and releasing it immediately after.

Hi Joy,
Of course we all do use it with modal forms where applicable. But think of this, what would you do if you need four return values ? Or would the return parameters would change based on the intermediate results of caller ? Modal forms wouldn't let you change something on caller form and would nearly be impossible to implement with ease in SDI forms. So think of this approach too :

do form myModeless with myVar, thisform  && Pass also form reference
*myModeless.init
lparameters cVar, oCallerRef
thisform.oCaller = oCallerRef   && A custom form property

* Any PEM
thisform.oCaller.anyPEM     && Now you can directly change 
                            && or call any PEM of caller form
