CODE

Int Initialization(Int PortNum, HWND hWnd, HINSTANCE HInst)

WinSock for VB & VB.Net

i know that VB 6 is using WinSock to create the TCP/IP connection. But how bout VB.NET? it still using WinSock? or other?

Anything wrong with my code?

Dim VersionNum As String

<DllImport("Vertx.dll")> Public Shared Function GetDLLVersion(ByRef VersionNum As String, ByVal DataSize As Integer) As Integer
End Function

GetDLLVersion(VersionNum, 10)

------------------------------------------------------------------------
note: the original structure of the GetDLLVersion is:

int GetDLLVersion(Char *data, int datasize)
data = array to caontain the DLL Version
datasize = size of data

So, the original structure should be a C language, thus i try to store the *data into the variable name VersionNum using the method of ByRef, is this wrong?

Can anyone help me to understand this?

i currently doing a project which is use a vb.net program to control a hardware device connected to the pc using a TCP/IP connection. But the problem i having now is to include the dll file into my program.

First, is that all dll file compatible with vb.net? cox i dont ever know what application was used to create that dll file (it come with the hardware when i bought it). I tried to add the dll file by using the "Add Reference" function, but it prompt out a message and inform me that the dll file is not a assembly or COM component.

Second, if all dll file can be include, then what is the relevant keyword that i can search for the example or source code to include a dll file?

Hope somebody can help me with this. Thanks
