VB2005,如何搜索局域网上的SQL主机?
如题

[解决办法]
引用SQLDMO.DLL(Microsoft SQLDMO Object Library),:\program files\microsoft sql server\80\tools\binn\sqldmo.dll

SQLDMO.NameList serverName = new SQLDMO.Application().ListAvailableSQLServers();
if (serverName != null && serverName.Count > 0)
for (int index = 1; index <= serverName.Count; index++)
MessageBox.Show((string)serverName.Item(index));
