Hi all,
I was trying to write an interface to change an IP Address on a PC
programatically. I used netsh and tested it in WinXP and it was OK
The person who I wrote it for said it was not working in his environment
which was 2000. I then did some serious digging and got the undocumented
ip helper function called

SetAdapterIpAddress



which function I prototyped as ...

#include "iphlpapi.h"


typedef DWORD (WINAPI *PSETADAPTERIPADDRESS)(
const char*,DWORD,DWORD,DWORD,DWORD
);

declared as...
PSETADAPTERIPADDRESS SetAdapterIpAddress;


and got a function address like......

hLib = LoadLibrary("Iphlpapi.dll");
SetAdapterIpAddress = 
(PSETADAPTERIPADDRESS)GetProcAddress(hLib,"SetAdapterIpAddress");


And use like this....

//-------------------------------------------------------------------------------------
#include "iphlpapi.h"


    bool ChangeAdaptorAddress(AnsiString A, AnsiString B, AnsiString C)
    {
      IPAddr A1, B1, C1;

      A1 = inet_addr(A.c_str());
      B1 = inet_addr(B.c_str());
      C1 = inet_addr(C.c_str());
      int retvalue  = SetAdapterIpAddress(card.c_str(), 0, A1, B1, C1);
//     ShowMessage(retvalue );
    }

In my environment, retvalue return 0
in the 2000 environment it returns 2

card is the uuid address taken from the registry.
0
mean no DHCP.

I know this is a toughy and no guarantees for help
but I need to set the address without restarting the PC

If anyone has an Idea how to get this working
let me know.

(2 - is like 'File Not found' or something)
