/Files/rttw/Excel.zip

本程序用來將多個excel報(bào)表合并成一個文件，取第一個文件的前n行做為報(bào)表的題頭，n可自定義。

1.支持直接添加多個文件

2.支持直接添加某個文件夾下面的所有excel文件

3 支持直接將excel文件拖放到程序界面

4.可以單選或多選記錄然后用右鍵刪除

5.可以定義excel表頭記錄數(shù)

6.本版本暫時只支持合并Excel文件的第一個sheet

7.雙擊某條記錄可直接刪除

8.開發(fā)環(huán)境 VC6+OFFICE2007，其他版本OFFICE有可能不兼容

北京寄來的件,已經(jīng)第四天了,打電話到廣州中轉(zhuǎn),說還沒到廣州,竟然讓我自己打電話到北京去問.再說了兩句竟然掛了我的電話.簡直是垃圾啊.客戶打電話上來的有問題的件應(yīng)該是快遞公司內(nèi)部處理解決吧,竟然讓客戶自己去跟蹤??奉勸大家以后千萬不要用申通快遞,切記且記

select * from a,b where a.id=b.id(+);
select * from a left join b on a.id=b.id;

很多資料說上面兩個語句的效果是一樣的,實(shí)際上今天經(jīng)過測試發(fā)現(xiàn)兩者的執(zhí)行計(jì)劃大不相同(查詢結(jié)果是一樣的);
至于為什么會這樣,暫時沒有深究,手頭的一個例子表明按照第一種寫法的效率會高,或許其他的例子結(jié)果不一樣,等有時間的時候再測試一下吧.

同樣的一條語句，一條是在pl/sql里面組裝成sql之后提交執(zhí)行，另外一條是用pro*c程序后綁定執(zhí)行，沒想到執(zhí)行策略和效率天差地別。看來做什么事都不能想當(dāng)然，要細(xì)心學(xué)習(xí)才行。保留此條語句以做紀(jì)念:

select *
? from (select /*+ INDEX(A IDX_HISBUFAREJOUR_ACCOUNT) +*/
???????? a.*, f.sort_name
????????? from hs_his.hisbufarejour a, hs_fund.faresort f
???????? where (((((((a.fare_sort = f.fare_sort and a.client_id = :b0) and
?????????????? (:b1 = 0 or a.fund_account = :b2)) and
?????????????? a.init_date >= :b3) and a.init_date <= :b4) and
?????????????? (trim(:b5) is null or
?????????????? instr(((',' || :b6) || ','),
???????????????????????? ((',' || a.exchange_type) || ',')) > 0)) and
?????????????? (trim(:b7) is null or

??????????????????????? ((',' || a.money_type) || ',')) > 0)) and
?????????????? (trim(:b9) is null or a.position_str > :b10))
???????? order by a.position_str)

vc的對話框中，如果直接用picturebox作為對話框的背景，則其他控件會被擋住。經(jīng)過高手指點(diǎn)，重載了WM_ERASEBKGND消息處理函數(shù)，很少的解決了這個問題。而且按照這個思路，可以很方便的為dialog增加動態(tài)的skin:

聲明消息處理函數(shù):

?// Generated message map functions
?//{{AFX_MSG(Input)
?afx_msg BOOL OnEraseBkgnd(CDC* pDC);
?afx_msg void OnButtonOk();
?afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);
?afx_msg void OnPaint();
?//}}AFX_MSG
?DECLARE_MESSAGE_MAP()

聲明消息循環(huán):
BEGIN_MESSAGE_MAP(Input, CDialog)
?//{{AFX_MSG_MAP(Input)
?ON_BN_CLICKED(IDC_BUTTON_OK, OnButtonOk)
?ON_WM_LBUTTONDBLCLK()
?ON_WM_PAINT()
?ON_WM_ERASEBKGND()
?//}}AFX_MSG_MAP
END_MESSAGE_MAP()

實(shí)現(xiàn)：
BOOL Input::OnEraseBkgnd(CDC* pDC)
{
?if(m_hBmp)
?{
??BITMAP bm;
??GetObject(m_hBmp,sizeof(bm),&bm);
??HDC hMemdc=CreateCompatibleDC(pDC->m_hDC);
??if(hMemdc)
??{
???? HBITMAP hOldBmp=(HBITMAP)SelectObject(hMemdc,m_hBmp);
???? if(hOldBmp)
???? {
????? BitBlt(pDC->m_hDC,0,0,bm.bmWidth,bm.bmHeight,hMemdc,0,0,SRCCOPY);
????? SelectObject(hMemdc,hOldBmp);
????? DeleteDC(hMemdc);
????? DeleteObject(hOldBmp);
????? return TRUE;
???? }
???? else
??? DeleteDC(hMemdc);
??}
?}
?return CDialog::OnEraseBkgnd(pDC);
}
