i try the following code on my own computer, it can access to the database (the database on my own computer).

However, when i run this code on another computer, it cannot access to the database which is located on my computer


xxx.xxx.xxx.xx is the ip address of my own computer (which launch the MSSQL)

i try whole days, but still no idea :/
can anyone give me some suggestions?
Thank you very much!

QString serverName = "xxx.xxx.xxx.xx\\SQLEXPRESS";
QString dbName = "myDB";
QString dbID = "sa";
QString dbPW = "abcd";

QSqlDatabase db = QSqlDatabase::addDatabase("QODBC");
QString dsn = QString("DRIVER={SQL Server Native Client 10.0};SERVER=%1;DATABASE=%2;UID=%3;PWD=%4;").arg(s erverName).arg(dbName).arg(dbID).arg(dbPW);

db.setDatabaseName(dsn);
