As per the QTP:

The DotNetFactory object in QTP enables you to create an instance of a .NET object, and access its methods and properties.

You can use this object to access the static methods and properties of a class that does not have an instance constructor, for example, System.Environment, as well as a class that does.

Also the .Net Add-in is not required for this to work. I personally feel that the utility has been introduced to resolve the problem that occured when referencing a .Net Assembly or C/C++ DLL and making a call to its functions.

The piece of code would be as in the following:

Set myMessageBox = DotNetFactory.CreateInstance (TypeName [,Assembly] [,args])

Set myMessageBox =

DotNetFactory.CreateInstance("System.Windows.Forms.Form",

"System.Windows.Forms")

myMessageBox.Show()


Create the custom UI forms part of my automation test framework so the tester can run opted test scripts as per the user's choice using the .Net factory utility:
