求指导，PB12.0 如何用ini文件 连接sql 2005数据库
我的dbconnect.ini文件内容

[Database]
DBMS=ADO.Net
Database=
UserId=
DatabasePassword=19ee3e1f625f6c8055b5747396669c0c
LogId=sa
LogPassword=4f7075b8febed3dd8655417e208b410f
ServerName=
DBParm=Namespace='System.Data.OleDb',Provider='SQLOLEDB',DataSource='OEM-20131031PEE',Database='mytest'
Lock=
Prompt=FALSE
AutoCommit=FALSE
NewLogic=EAS
-------------------------------------------------------------

我的open()事件里的内容

string str_file
//获取数据库配置文件，目录相对当前应用程序根目录
str_file = "dbconnect.ini"
// 判断指定的INI文件是否存在
if not FileExists (str_file) then
   messagebox("提示！","ini文件不存在！",exclamation!,ok!,2)
 return
end if

SQLCA.DBMS       = ProfileString(str_file,"database","DBMS"," ")
SQLCA.Database   = ProfileString(str_file,"database","DataBase"," ")
SQLCA.LogID      = ProfileString(str_file,"database","LogID"," ")
SQLCA.LogPass    = ProfileString(str_file,"database","LogPassword"," ")
SQLCA.ServerName = ProfileString(str_file,"database","ServerName"," ")
SQLCA.UserID     = ProfileString(str_file,"database","UserID"," ")
SQLCA.DBPass     = ProfileString(str_file,"database","DatabasePassword", " ")
SQLCA.Lock       = ProfileString(str_file,"database","Lock"," ")
SQLCA.DbParm     = ProfileString(str_file,"database","dbparm"," ")
SQLCA.autocommit = false
connect using sqlca;
open(w_test)

1.密码在ini里加密了.你读取出来连数据库的时候解密了吗?
2.没连上数据库,把sqlerrtext打出来自己研究吧
