2，c用戶界面登陸密碼和用戶名如何與SQL數(shù)據(jù)庫(kù)對(duì)照

用一條查詢語(yǔ)句，如果得到的結(jié)果集有一條數(shù)據(jù)就為真，進(jìn)入程序下一步，否則返回Return,例如：select * from tablename where name = extbox1.text,pw = textbox2.text獲取結(jié)果集dataset.table(tablename).rows.count 如果大于0 則為真。否則為假。http://hi.baidu.com/jonesvale/blog/item/15afaecd2c66661800e9285f.html

步驟：1。創(chuàng)建數(shù)據(jù)庫(kù)連接，如果連不上，報(bào)錯(cuò)，返回登錄界面。2。連上后，根據(jù)用戶名去讀保存user信息的那個(gè)數(shù)據(jù)表，得到該user的信息，如密碼，級(jí)別，權(quán)限等等。3。如果不存在此user，報(bào)錯(cuò)，返回登錄界面。4。存在此user,判斷密碼是否相等，相等則進(jìn)行主程序界面，不等就報(bào)錯(cuò)。ps:1。可以整個(gè)報(bào)錯(cuò)的類統(tǒng)一處理。2。user表中的密碼應(yīng)該是加密后的，最好別用明碼。

怎樣做登陸系統(tǒng) 創(chuàng)建兩個(gè)textbox和commandbutton控件分別為 txtuser txtpwd cmdlogin cmdexit 其中 txtpwd的passwordchar 設(shè)為 * 實(shí)例代碼 optional explicit dim lngcount as long private sub form_load() lngcount=2 end sub private sub cmdexit() end end sub private sub cmdlogin() if txtuser.txt="zh" and txtpwd.txt="12345" then form2.show form2為主界面窗口 unload me else lngcount=lngcount-1 if lngcount<>0 then msgbox "用戶名密碼沒(méi)有填寫或輸入錯(cuò)誤共給2次機(jī)會(huì) 還剩" & lngcount & "次",16+vbokonly,"輸入錯(cuò)誤" else msgbox "已超過(guò)最大錯(cuò)誤次數(shù) 程序即將退出.",16 + vbokonly,"輸入錯(cuò)誤" end end if end if end sub
