ODBC连接在家里电脑上试的好好的，换机器就成这样了
QSqlDatabase Sqlwindow::db = QSqlDatabase::addDatabase("QODBC");
void Sqlwindow::connectDatabase()
{
db.setHostName("127.0.0.1");
db.setUserName("smkt");
db.setPassword("smkt1999");
db.setDatabaseName("smkt");
bool bRet = db.open();
if(!bRet)
{
QCoreApplication::addLibraryPath("./plugins");
QMessageBox::critical(NULL,"操","陆毅的机器又抽风了"+db.lastError().text());
// QMessageBox(,，)"error open database"<<;
db.lastError();
exit(0);
}
qDebug()<<"open database success";
Starting D:\hlg\debug\syxt.exe...
QSqlDatabase: QODBC driver not loaded
QSqlDatabase: available drivers: QSQLITE QMYSQL QMYSQL3 QODBC QODBC3 QPSQL QPSQL7
QSqlDatabase: an instance of QCoreApplication is required for loading driver plugins
D:\hlg\debug\syxt.exe exited with code 0
plugins拷的到处都是。都找不到。这么个破数据库直接让连上不就得了，
