determining an IP address........

how would i be able to determine what my IP address it through VB? thanks!

Add the Microsoft Winsock Control to your form and use this:

Code:

---

MyIPAddress = Winsock1.LocalIP

---

Hope this helps.

You can also use api to do it.

'Add a textbox (Text1) And a Command button (Command1) To a New form And use the
following code:

'Usage: Fill in the textbox with the name you want to resolve and click the
command button to resolve the name.

WOW
I think I'll stick with the winsock control. :D
