vb.net – IP-Input-Box like windows

Hello,

I want to have a manual IP-input-box like windows.

tcpip_properties.gif

I tried by MaskedTextBox but the problem is, the 3 pionts are sliding when i insert some numbers and i can insert letters and numbers higher then 255 (higher is not allowed in IP´s).

I hope anyone helps me, maybe with some codesnips!?! :)

best regards
josh
