获得网上邻居列表的程序
程序如下：
var
i : Integer;
ErrCode : Integer;
NetRes : Array[0..1023] of TNetResource;
EnumHandle : Thandle;
EnumEntries : Dword;
BufferSize : Dword;
ComputerIP,ComputerName:String;
begin
//try
With NetRes[0] do begin
dwScope :=RESOURCE_GLOBALNET;
dwType :=RESOURCETYPE_ANY;
dwDisplayType :=RESOURCEDISPLAYTYPE_DOMAIN;
dwUsage :=RESOURCEUSAGE_CONNECTABLE;
lpLocalName :=NIL;
lpRemoteName :=NIL;
lpComment :=NIL;
lpProvider :=NIL;
end;
{ get net root }
ErrCode:=WNetOpenEnum(
RESOURCE_GLOBALNET,
RESOURCETYPE_ANY,
RESOURCEUSAGE_CONTAINER,
@NetRes[0],
EnumHandle
);

If ErrCode=NO_ERROR then begin
EnumEntries:=1;
BufferSize:=SizeOf(NetRes);
ErrCode:=WNetEnumResource(EnumHandle,EnumEntries,@NetRes[0],BufferSize);
WNetCloseEnum(EnumHandle);
ErrCode:=WNetOpenEnum(
RESOURCE_GLOBALNET,
RESOURCETYPE_ANY,
RESOURCEUSAGE_CONNECTABLE,
@NetRes[0],
EnumHandle
);
EnumEntries:=1024;
BufferSize:=SizeOf(NetRes);
ErrCode:=WNetEnumResource(
EnumHandle,
EnumEntries,
@NetRes,
BufferSize
);

for i:=0 to 1023 do
if NetRes[i].lpRemoteName='' then Exit
else begin
ComputerName:=Copy(NetRes[i].lpRemoteName,3,Length(NetRes[i].lpRemoteName)-2);
ComputerIP:=GetIP(ComputerName);
ShowMessage('计算机名' + NetRes[i].lpRemoteName + chr(13)
+ '计算机说明:' + NetRes[i].lpComment + chr(13)
+ 'IP地址:' + ComputerIP);
end;
end;
