SetDlgItemText

I would like to know how to Set A Value to a control, EDIT1.(I'm using Dialog).

You answered your question in your thread title :rolleyes:

I don't know how to use it... Can you show me how?

Here is an example:

PHP Code:

---

SetDlgItemText(dlghwnd, EDIT1, "This is a string."); 


---

You can always look up at MSDN Library for reference on any of the API calls.
