Windows Network

How do I find which computers are available on a Windows network?

I experimented with IShellFolder, but no success.

Thx in advance

I should write this down some where, because this is a first and will probably never happen again ;)

Anyways I tried to figure this out once before but only had limited success. In the end I just threaded a ping class and pinged the network looking for vaild IPs. Then tried to resolve the name of the IP. If it couldnt resolve then I assumed it wasnt a computer. I was a good enough answer for what I needed at the time.

But I believe that windows just sends out a NetBIOS broadcast and then resolves the names of those that respond. So if you can figure out how to get NetBIOS working you should be able to figure it out. I did a search on SourceForge.net and found a bunch of source code for NetBios, and Network Browse. Something in there should help going in the right direction.

That's stupid, I can't imagine Explorer being implemented this way.


I'll take a look at the IRemoteComputer interface, maybe that'll take me further.

BTW it's not my first question here, if that's what you're referring to :)

It's about my 8th ;)

I will have to look at the other 8 questions then

No one ever claimed MS was good at networking.

I found this code it MFC :( but it might help

Code:

---

#include "winnetwk.h"
#pragma comment (lib, "mpr")

...

void EnumLocalNetwork(NETRESOURCE *lpnr)
{
  HANDLE hEnum;
  DWORD cEntries = -1, cbBuffer = 0x4000;
  if (::WNetOpenEnum(RESOURCE_GLOBALNET, RESOURCETYPE_ANY, 0, lpnr, &hEnum) == 0) {
      if ((lpnr = (LPNETRESOURCE)::GlobalAlloc(GPTR, cbBuffer)) != NULL) {
        while (::WNetEnumResource(hEnum, &cEntries, lpnr, &cbBuffer) == 0) {
            for  (int ctr = 0; ctr < (int)cEntries; ctr++) {
              if (lpnr[ctr].dwDisplayType == RESOURCEDISPLAYTYPE_NETWORK ||
                  lpnr[ctr].dwDisplayType == RESOURCEDISPLAYTYPE_DOMAIN)
                    EnumLocalNetwork(&lpnr[ctr]);
              else {
                  AfxMessageBox(lpnr[ctr].lpRemoteName);
              }
            }
            cEntries = -1;
            cbBuffer = 0x4000;
        }
        ::GlobalFree(lpnr);
      }
      ::WNetCloseEnum(hEnum);
  }
}

void CMFDDLGDlg::OnOK()
{
  EnumLocalNetwork(NULL);
  MessageBox("DONE");
}

Thanks a lot. Will try it out tomorrow.

Huh huh, even I wuddent get that wrong.

:D :thumb: :D

Man some times you guys are too pick :rolleyes:

Arrrgh! Found out I already did it correctly and the error was somewhere else!

No, wait, I didn't...

Ok, got it now. Thanks for that code Tech.

Your welcome
Glad to help you for a change :D

I wrote a custom iterator that iterates over all filesystem roots and network shares, compatible with the boost filesystem library. Only needs a bit of error checking now.
