CREATEOBJECT or NEWOBJECT 1

[vhad]

Hi All,

I'm new with Foxpro, could somebody tell me what is the different between CREATEOBJECT and NEWOBJECT ?
And when should I use CREATEOBJECT or NEWOBJECT ?

Thank you in advance.

Hi!

Createobject is used by a more generic way. It could be used the same way as a NEWOBJECT with a few differences:
- Createobject, when creating VFP object from custom class, requires that the custom class library/PRG is loaded in the memory by SEL CLASSLIB/ SET PROCEDURE commands. Nowobject has a parameter that specifies the class module, so it is not required to be loaded. In addition, NewObject can specify the application (APP or EXE) that contains that class definition.
- NewObject, when called as a method of the cntainer object (for example, form.NewObject(...) ), can add a VFP object to the container.

Thank you very much Vlad,

It helps a lot.

I want to develop an executable (EXE) application.
And the main user interface for the application is menu, launched using 'do mymenu.mpr' from main program.

I believe this must be the Main VFP Window.
So, could I use NewObject to add an Object to main VFP window ?
Should I use _SCREEN.NewObject("classname","classlib.vcx&quot or _VFP.NewObject("classname","classlib.vcx&quot ?

Hope you understand.

Once Again Thanks.

Hi!

_VFP is not a container object. _SCREEN is a container (it is a form class). So use _SCREEN.
