mobile based application connect to PC!!!

i'm writing a chatting application for PDA, below is my code for establish connection to computer(the ip address is the router ip address)........but i still new for mobile programming....now i ask for some opinion whether it will work in PDA or not?

VB Code:

Const mBufferSize As Integer = 255 
    Private mBuffer(mBufferSize) As Byte 
    Private sendBuffer(mBufferSize) As Byte 
    Public Shared mSocket As Socket 
 
    Public Sub Connect() 
        mSocket = New Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp) 
        mSocket.BeginConnect(New IPEndPoint(IPAddress.Parse("192.168.0.111"), 8080), AddressOf Connected, mSocket) 
    End Sub 
 
    Public Sub Connected(ByVal ar As IAsyncResult) 
        mSocket = DirectCast(ar.AsyncState, Socket) 
        mSocket.EndConnect(ar) 
 
        MsgBox("Connected") 
 
        mSocket.BeginReceive(mBuffer, 0, mBufferSize, SocketFlags.None, AddressOf getMessage, mSocket) 
 
End Sub

I posted a set of classes that I use to do something like that in your post in the .NET forum. There are a few differences in the socket settings, but compare the two.
