I have a web form that I can not modify, which receives customer data when a partial name is entered into the form.

I am trying to write a C# process that will capture the data from the 'last name' textbox field, when it is populated by the form.


I thought about searching for the memory address and grabbing the data there, but I am worried the memory locations will change upon each new form being loaded.

I also thought about using a winsock listener.



I have a mountain of Wrox books and have experience with the tutorials, but this function that I need to add to my project is not in any of those books.

What is the simplest method to achieve this?


Thank you for any assistance.
