Find Text box and set text in External application

Hello,

I need to find a text box and set text on it in an external application.

I know how to find the external application and the text box. However, I am stuck as there are two text boxes which are blank and am not sure how to find the second one.

They both have same class name.

How to find the one which i need ?

Thanks in advance.

Well you can enumerate the child windows and get eachs Control ID until the one you need matches. The Control IDs are like serial numbers
