使用方法：
在程序的全局模块中定义CSetting的类实例变量：（以下定义了两个，分别读写ini和注册表）
Public SetIni As CSetting '读写ini配置文件参数 '
Public SetReg As CSetting'读写注册表配置参数
在sub main 中初始化：(其中PATH_EXE是你的程序路径，放ini文件的路径)
Set SetIni = New CSetting
SetIni.Init PATH_Exe, App.Title, csModeINI
Set SetReg = New CSetting
SetReg.Init PATH_Exe, App.Title, csModeRegistry
这就可以随便用了。
dbPassword = SetIni.GetSettingStr(NameDB, "Password", "111111")
dbUserID = SetIni.GetSettingStr(NameDB, "UserID", "123456")
dbCatalog = SetIni.GetSettingStr(NameDB, "Catalog", "aaa")
dbDataSource = SetIni.GetSettingStr(NameDB, "DataSource", sky)
cnStr= "Provider=SQLOLEDB.1;Password=" & dbPassword & ";Persist Security Info=True;User ID=" & dbUserID & ";Initial Catalog=" & dbCatalog & ";Data Source=" & dbDataSource '
其它由你自己补充了。
