Windows NT 4.0 had WIPCfg32.exe, and Windows 95/98/ME had WinIPCfg.exe. For some reason, this utility was removed from Windows 2000/XP. This program is a clone of WinIPCfg.exe, written for Windows XP. For those of you who are unfamiliar with WinIPCfg, it looks like this:

  • gateway problem

    Hello, On WinMe the gateway is not displayed, but on Win XP it is. Do you know why? Thanks.

      Actually the gateway is not displayed for a wireless adapter, but using the winipcfg original application it is displayed.

    The utility runs great on W2k, but generates an exception on XP at startup.

      Greetings! You mentioned that you were going to revise the code and repost it - did that happen? Thanks. P.S. Error signature on XP SP1, FYI: AppName: winipcfg.exe AppVer: ModName: winipcfg.exe ModVer: Offset: 000030f3

      Great! That explains it. I will update the code and get it reposted. Thanks.

    • Exception on Win2000

      Posted by mpauley1955 on 11/09/2005 09:24am

      I also got an exception on startup, but running Win 2000. 
      The problem seems to be when you have multiple adapters. 
      In the CWinIPCfgDlg::GetNICs routine you use GetAdaptersInfo() to load a buffer with the adapter info, then load the combobox item data with it. 
      You step through the returned data as if it were an array:
      	// Add each entry to the combobox
      	for(int i = 0; i < nCount; ++i)
      		CString sName = pIPAI[i].Description;
      		m_cbNetCard.SetItemData(i, (DWORD_PTR)&pIPAI[i]);
      but it is actually a linked list. I changed it to this:
      // pIPAI is a pointer to a linked list of IP_ADAPTER_INFO structures.
      // The last valid one has it's "Next" member set to NULL.
      // Just walk the chain...
      	int i;
      	while ( pIPAI != NULL )
      		CString sName = pIPAI->Description;
      		i = m_cbNetCard.AddString(sName);
      		m_cbNetCard.SetItemData(i, (DWORD_PTR)pIPAI);
      		pIPAI = pIPAI->Next;
      and it works fine now.

      Can you give me more details? I have dozens of users on the networks that I support using this right now. If there is an issue, I would like to figure it out.

      This is for those of us that don't use command line (most of the users I support).
