'Add this code to the form's General Declarations procedure:

Text2 = GetIPAddress()
'or you could just do this
Code:'Add a winsock control and a textbox,
'and add this code
Text1.Text = Winsock1.LocalIP
More simple..
add a Microsoft Winsock Control
and type this little command:
Code:MsgBox Winsock1.LocalHost
Actually pro2, it's:
And HeSaidJoe contains that in his code.Code:Msgbox Winsock1.LocalIP
Quote:
Code:'or you could just do this
'Add a winsock control and a textbox,
'and add this code
Text1.Text = Winsock1.LocalIP
yes I know..
it's beacause I dont saw the code of HeSaidJoe the first time..
and this line is wrong:
this is the good one .. :Code:Public Const WS_VERSION_MAJOR As Long = WS_VERSION_REQD \ & H100 And &HFF&
de mistake is the space here:Code:Public Const WS_VERSION_MAJOR As Long = WS_VERSION_REQD \ &H100 And &HFF&
Stupid mistake I know but it make an error..Code:& H100
now I understant..
it's the CODE control who put a space..
This is the good way :
&H100
NO SPACE
It's a bug. No matter how many times you try and type it, it will always mess up, but everyone understand the idea anyway.
