sqlite3數(shù)據(jù)庫，簡單而功能強大，比起ini文件保存用戶設(shè)置，更簡單安全，為什么使用數(shù)據(jù)庫存用戶設(shè)置，由開發(fā)者自己去想吧

進入話題：

pb中可以用ole DB方式在不注冊odbc的情況下直接連接數(shù)據(jù)庫，下面直接給出代碼，供有需要的參考

一、下載sqliteodbc.exe,具體下載位置，直接到網(wǎng)上搜索一下，其實只是需要里面的一個sqlite3odbc.dll這個文件

二、在PB中打開Database Profiles配置選項

Provider選擇MSDASQL

Extended Properties:Driver=SQLite3 ODBC Driver;Database=D:workSpacePBPenavicoqdcfg.db;PassWord=

注意在沒有安裝sqliteodbc的情況下，必須手工注冊SQLite3 ODBC Driver項值

如下圖

// Profile cfg
SQLCA.DBMS = "OLE DB"
SQLCA.AutoCommit = False
SQLCA.DBParm = "PROVIDER='MSDASQL',PROVIDERSTRING='Driver=SQLite3 ODBC Driver;Database=D:workSpacePBPenavicoqdcfg.db;PassWord='"

自動注冊SQLite3 ODBC Driver

public?function?boolean?pub_f_put_sysvar?(string?as_varcode,?any?aa_varvalue);//Public?function?pub_f_put_sysvar?(string?as_varcode,any?aa_varvalue)?returns?boolean?
//string?as_varcode
//any?aa_varvalue

RETURN?pub_f_put_sysvar(as_varcode,aa_varvalue,TRUE)

end?function

	end?if
//end?if

Return?True
