/Files/rttw/Excel.zip

本程序用來將多個(gè)excel報(bào)表合并成一個(gè)文件，取第一個(gè)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(gè)文件

2.支持直接添加某個(gè)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(shí)只支持合并Excel文件的第一個(gè)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(jiǎn)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

很多資料說上面兩個(gè)語句的效果是一樣的,實(shí)際上今天經(jīng)過測(cè)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(huì)這樣,暫時(shí)沒有深究,手頭的一個(gè)例子表明按照第一種寫法的效率會(huì)高,或許其他的例子結(jié)果不一樣,等有時(shí)間的時(shí)候再測(cè)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

vc的對(duì)話框中，如果直接用picturebox作為對(duì)話框的背景，則其他控件會(huì)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(gè)問題。而且按照這個(gè)思路，可以很方便的為dialog增加動(dòng)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);
}

??????今天系統(tǒng)莫明其妙的故障,以前用的好好的客戶信息匯總統(tǒng)計(jì)突然出現(xiàn)異常,查看日志顯示oracle的sql語句異常.
??????跟蹤調(diào)試后臺(tái)發(fā)現(xiàn)問題出現(xiàn)在sprintf語句上面,sql預(yù)定義 char[8000],然后用sprintf來格式化,結(jié)果當(dāng)語句的數(shù)據(jù)超過8000的時(shí)候就不能正常處理了.
???? google了一下:

眾所周知,sprintf不能檢查目標(biāo)字符串的長(zhǎng)度，可能造成眾多安全問題,所以都會(huì)推薦使用snprintf.

snprintf(_snprintf)的聲明是這樣的

int _snprintf(
?? char *buffer,
?? size_t count,
?? const char *format [,
????? argument] ...
);

If len < count, then len characters are stored in buffer, a null-terminator is appended, and len is returned.

If len = count, then len characters are stored in buffer, no null-terminator is appended, and len is returned.

If len > count, then count characters are stored in buffer, no null-terminator is appended, and a negative value is returned.

最常見的錯(cuò)誤用法有:
1.
char sa[256]={0};
_snprintf(sa,sizeof(sa),"%s",sb);
//錯(cuò)誤原因:當(dāng)sb的長(zhǎng)度>=256的時(shí)候,sa將沒有'\0'結(jié)尾

2.
char sa[256];
_snprintf(sa,sizeof(sa)-1,"%s",sb);
//錯(cuò)誤原因:當(dāng)sb的長(zhǎng)度>=255的時(shí)候,sa將沒有'\0'結(jié)尾,忘記給sa初始化

3.
char sa[256];
_snprintf(sa,sizeof(sa)-1,"%s",sb);
sa[sizeof(sa)]=0;
//錯(cuò)誤原因:最后一行數(shù)組越界

正確的用法
1. //推薦用法
char sa[256];
sa[sizeof(sa)-1]=0;
_snprintf(sa,sizeof(sa),"%s",sb);
if(sa[sizeof(sa)-1]!=0)
{
?? printf("warning:string will be truncated");
?? sa[sizeof(sa)-1]=0;
}

2.
char sa[256]={0};
int result = _snprintf(sa,sizeof(sa),"%s",sb);
if(result==sizeof(sa) || result<0)
{
??? printf("warning:sting will be truncated");
?? sa[sizeof(sa)-1]=0;
}

首先定義消息:

#define POST_DATA_START WM_USER+1
#define POST_DATA_END WM_USER+2
#define RECEIVE_DATA_START WM_USER+3
#define RECEIVE_DATA_END WM_USER+4
#define THREAD_START WM_USER+5
#define THREAD_END WM_USER+6
#define TASK_START WM_USER+7
#define TASK_END WM_USER+8
#define TASK_IDEL WM_USER+9

聲明處理函數(shù)
?//{{AFX_MSG(CMyDlg)
?........
?afx_msg void OnPostDataStart(WPARAM wParam, LPARAM lParam);
?afx_msg void OnPostDataEnd(WPARAM wParam, LPARAM lParam);
?afx_msg void OnReceiveDataStart(WPARAM wParam, LPARAM lParam);
?afx_msg void OnReceiveDataEnd(WPARAM wParam, LPARAM lParam);
?afx_msg void OnThreadStart(WPARAM wParam, LPARAM lParam);
?afx_msg void OnThreadEnd(WPARAM wParam, LPARAM lParam);
?afx_msg void OnTaskStart(WPARAM wParam, LPARAM lParam);
?afx_msg void OnTaskEnd(WPARAM wParam, LPARAM lParam);
?afx_msg void OnTaskIdel(WPARAM wParam, LPARAM lParam);
?//}}AFX_MSG
?DECLARE_MESSAGE_MAP()
注意所有函數(shù)聲明都要在 DECLARE_MESSAGE_MAP()前面

綁定消息和處理函數(shù)：
BEGIN_MESSAGE_MAP(CMyDlg, CDialog)
//{{AFX_MSG_MAP(CMyDlg)
ON_MESSAGE(POST_DATA_START,OnPostDataStart)
ON_MESSAGE(POST_DATA_END,OnPostDataEnd)
ON_MESSAGE(POST_DATA_START,OnReceiveDataStart)
ON_MESSAGE(RECEIVE_DATA_START,OnReceiveDataEnd)
ON_MESSAGE(RECEIVE_DATA_END,OnThreadStart)
ON_MESSAGE(THREAD_START,OnThreadEnd)
ON_MESSAGE(TASK_END,OnTaskStart)
ON_MESSAGE(TASK_START,OnTaskEnd)
ON_MESSAGE(TASK_IDEL,OnTaskIdel)

//}}AFX_MSG_MAP
END_MESSAGE_MAP()

當(dāng)然最后還要完成函數(shù)實(shí)體

新裝的redhat linux，先增加系統(tǒng)用戶，然后

cat /etc/passwd|mksmbpasswd.sh > /etc/samba/smbpasswd
此命令根據(jù)系統(tǒng)的用戶文件 /etc/passwd自動(dòng)生成了samba的用戶文件

smbpasswd?
修改用戶登陸samba的密碼

service smb restart
重啟samba服務(wù)

通過以上三步可以用os用戶登陸samba(密碼不是os的，可以單獨(dú)改)，登陸后默認(rèn)可以訪問該用戶在os的home目錄

補(bǔ)充: 修改 [global]下面的 security = user為security = share可以允許匿名登陸,登陸后可以訪問的內(nèi)容可以用guest ok = yes 來標(biāo)記
