程式 - VB6你有遇到這樣情況嗎 ?增加資料表數據的時候，在datagrid中顯示總是少一筆條

[飛行船大大]

這張圖只是查詢畫面時：圖下方是access 開啟資料表中共有5筆, 圖上方是 vb6 用datagrid卻只有顯示出前4筆. 我以前沒遇到這情形, (以前 clipper語言中, 有一個指令 commit 就是專門將最後一筆 buffer強迫寫入 , vb6 中倒沒這種指令.)
所以覺得很奇怪.



---源碼貼出如下 (很單純的查詢所寄出的 e-mail電子報 ) 如下------------------------
(grdEDM 就是DATAGRID的控制項 )
(DTPicker(0) DTPicker(1) 就是查詢日期 開始和結束)
(資料表EDM 中 有一欄位 UseTime 是文字型態 放比對的日期)

(下方quote 源碼內容 奇怪會變成沒縮排 有點難以閱讀 , 不知道如何貼源碼才會變成有縮排 )
