Duplicate Client/Server DLL into Delphi XE2.

I would like duplicate the functions of these DLLs in Delphi XE2 so that I do not have to use the DLLs. There is a server side and client side. I would like to use the TCP components of the INDY server and client in XE2. I have included the original SDK documents for the DLLs and the DLL themselves. Below are the commands and functions that I would like duplicated in Delphi. The rest of the commands that are in the SDK I do not need. Please let me know Duplicate These Commands for the Server Side. DH_ServerStart DH_ServerCheckIP DH_ServerCheckPassword DH_ServerSetNetPort DH_ServerSetBufNum DH_ServerSetWait DH_ServerWriteDataEX The rest of the commands, functions and callbacks are not needed. Duplicate These Commands for the Client Side DH_ClientSetNetPort DH_ClientStart DH_ClientSetBufferNum DH_ClientStartCapture DH_ClientStop For the DH_ClientStart command I would like an extra parameter added. I would like a parameter named dUser of a type of Integer. Then in the callback I would like this added as well as part of the callback function. So in Delphi the DH_ClientStart command currently looks like this. function DH_ClientStart(VIDEOINFO:pCLIENT_VIDEOINFO; pReadDataCallBack:TReadDataCallBack):Integer; stdcall; external ‘dll'; The Callback currently looks like this. TReadDataCallBack=procedure (nport:ULONG; pBuffer: Pointer; dwBufSize: DWORD); stdcall; I would like the function to look like this. function DH_ClientStart(VIDEOINFO:pCLIENT_VIDEOINFO; pReadDataCallBack:TReadDataCallBack; dwUser:Integer):Integer; stdcall; external ‘dll'; And I would like the callback to look like this. TReadDataCallBack=procedure (nport:ULONG; pBuffer: Pointer; dwBufSize: DWORD;dwUser:Integer); stdcall; So that each time the callback is called it would output the dwUser that it input into it at the DH_ClientStart. So that you could call the DH_ClientStart multiple times and a unique identifier to tell them apart.
