folgendes prob:
wollte mit eine auflistung aler rechner im netzwerk machen. aber ich bekomme bei der WNetOpenEnum funktion immer den fehler: 487 (ERROR_INVALID_ADDRESS).

da zur zeit glaskugeln ziemlich rar sind, bisschen code:

NETRESOURCE nr;
   HANDLE hEnum;

   nr.dwScope = RESOURCE_GLOBALNET;
   nr.dwType = RESOURCETYPE_ANY;
   nr.dwDisplayType = RESOURCEDISPLAYTYPE_DOMAIN;
   nr.dwUsage = RESOURCEUSAGE_CONTAINER;

   DWORD error = WNetOpenEnum(
                 RESOURCE_GLOBALNET,RESOURCETYPE_ANY,0,&nr,&hEnum);
   if(error)
   {
      ShowMessage(error);
      return;
   }
   WNetCloseEnum(hEnum);

das ist nur mal ne kleine testfunktion zum ausprobieren.
ich hab aber irgendwie keinen plan was ich da falsch mache.
kann mir da jemand weiterhelfen ?

noe, nuetzt leider auch nix. bleibt unveraendert.
sonst noch jemand ideen ?

Ich habe das selbe in VB gemacht (in C++ kommts nocht)
Dort brauche ich allerdings NetServerEnum

im der MSDN hat es einen Betrag dazu.

ich hoffe, das hilft dir weiter
