Works as an OLE insertable Object

I can insert it on a VFP form, assign it to a Object variable.
If I double-click on it, I can use it as any other ActiveX control on my
form.
I just want to know its properties to be able to read/write, in code, a
value in
one of its cell.

I have created a form, with a command button on it
In Click Event:

THISFORM.AddObject('oWks2',"Olecontrol",'MSWorks.Sheet.4')

WITH THISFORM
.oWks2.Top=.Top+10
.oWks2.Left=.Left+10
.oWks2.Height=.Height-20
.oWks2.Width=.Width-20
.oWks2.Visible=.t.
endwith

Until now, everything works just fine.

But from now on, I don't know how to continue (to write a value in a cell).

If anyone can help me, I will appreciate.

Thank you
