I have a text input box grayed out, but there is a default setting number inside "1234".

What functions should I be looking for ?

Thanks!

That was the first thing I tried.

Let me ask it this way, what function sets the default text inside an input box ? thanks

Try SetWindowText(). Despite the name, it sets the text property of many gui elements. There's no difference between default and current text, so it'll be called a lot of times.
