The type library of the latest version of iGrid ActiveX is "iGrid500_10Tec", and the class name of the control is "iGrid". A code snippet based on the CreateObject function you asked for might look like this:
Dim objGrid As Object
Set objGrid = CreateObject("iGrid500_10Tec.iGrid")
objGrid.ColCount = 2
objGrid.RowCount = 5
, but I doubt it's enough to make it work.
iGrid is a VISUAL ACTIVEX CONTROL and it is not intended for usage only from code. To instantiate it properly, it must be created on a form, which implies additional operations done on initialization - such as setting the control' parent host, binding event handlers, etc.
