数据库为什么无法连接？

[petertangh]

我在project的open里写入了如下代码：
SQLCA.DBMS = ProfileString("pb.ini","database", "DBMS", " ")
SQLCA.Database = ProfileString("pb.ini","database", "Database", " ")
SQLCA.LogId = ProfileString("pb.ini","database", "LogId", " ")
SQLCA.LogPass = ProfileString("pb.ini","database", "LogPassword", " ")
SQLCA.ServerName = ProfileString("pb.ini","database", "ServerName", " ")
SQLCA.UserId = ProfileString("pb.ini","database", "UserId", " ")
SQLCA.DBPass = ProfileString("pb.ini","database", "DatabasePassword", " ")
SQLCA.lock = ProfileString("pb.ini","database", "lock", " ")
open(w_main)

在主窗口写入了如下代码：
// Connect to the database.
CONNECT USING SQLCA;

IF SQLCA.SQLCode <> 0 THEN
MessageBox("Connect Failed", &
"Cannot connect to database " &
+ SQLCA.SQLErrText)
RETURN

END IF
dw_datawindow.SetTransObject(SQLCA)
dw_datawindow.Retrieve()
点击run后出现一消息框(Connect Failed)内容为：
Cannot connect to database DBMS is not suooirted in your current installation

顺便提一下我用的系统是windowxp，pb8.0会不会和他有关？

可能是你的直连所用的DLL文件找不到了！

可能问题
1 数据的DLL安装没有
2 AUTOEXEC.BAT中没有PB的路经

在PB中Profile连接正常吗？

如果正常那说明你客户端配置有问题，如果不正常请重新安装PB，选好数据库接口。
