C++操作Excel ,网上的资料还是比较多的，写这篇文章也是分享给初学者一些经验。
本人 觉得CSpreadSheet.h这个类封装的还不错。下面我就如何使用这个类介绍一下，
[cpp]
////////////////main.cpp/////////////////////////////////////////////////////
#include
#include
#include
#include "CSpreadSheet.h"
using std::string;
#pragma warning(disable:4146)
#pragma warning(disable:4786)
#import "C:\Program Files\Common Files\System\ado\msado15.dll" no_namespace rename("EOF","adoEOF")
//插入到
数据库
bool InsertExcel(CString str1,CString str2)
{
try
{
CDatabase m_db;
if (!m_db.IsOpen())
{
m_db.OpenEx("Dsn=MyDatabase;uid=Administrator;trusted_connection=Yes;app=Microsoft Visual Studio 2005;wsid=LIYU\SQLEXPRESS;database=MyDdatabase",0);
}
CString sql("insert into Students(myname,age) values('"+ str1+"','"+str2+"')");
m_db.ExecuteSQL(sql);
if(m_db.IsOpen())
{
m_db.Close();
}
return true;
}
catch(_com_error e)
{
string ErrorMessage("数据库连接关闭失败:"),Description,Source;
Description=e.Description();
Source=e.Source();
ErrorMessage+=e.ErrorMessage();
ErrorMessage=ErrorMessage+"\r\n"+Source+"\r\n"+Description;
::MessageBox(NULL,ErrorMessage.c_str(),"错误",MB_OK);
return false;
}
}
//获取路径
CString GetAddr()
{
CString sFile,sPath;
//获取主程序所在路径,存在sPath中
GetModuleFileName(NULL,sPath.GetBufferSetLength (MAX_PATH+1),MAX_PATH);
sPath.ReleaseBuffer ();
int nPos;
nPos=sPath.ReverseFind ('\\');
sPath=sPath.Left (nPos);
sFile = sPath + "\\Demo.xls";
return sFile;
}
[cpp]
//得到驱动
CString GetExcelDriver()
{
char szBuf[2001];
WORD cbBufMax = 2000;
WORD cbBufOut;
char *pszBuf = szBuf;
CString sDriver;
// 获取已安装驱动的名称(涵数在odbcinst.h里)
if (!SQLGetInstalledDrivers(szBuf, cbBufMax, &cbBufOut))
return "";
// 检索已安装的驱动是否有Excel...
do
{
if (strstr(pszBuf,"Excel") != 0)
{
//发现 !
sDriver = CString(pszBuf);
break;
}
pszBuf = strchr(pszBuf, '\0') + 1;
}
while (pszBuf[1] != '\0');
return sDriver;
}
[cpp]
//读取Excel
void ReadFromExcel()
{
TRY
{
CString str=GetAddr();
if(str.IsEmpty())
::MessageBox(NULL,"无法获取当前路径",NULL,MB_OK);
else
{
CSpreadSheet SS(str,"Students");
CStringArray Rows, Column;
CString strContents = "";
CString sItem[3]={"0"};
for (int i = 2; i < SS.GetTotalRows()+1; i++)
{
// 读取一行
SS.ReadRow(Rows, i);
strContents.Empty();
for (int j = 0; j < Rows.GetSize(); j++)
{
strContents = Rows.GetAt(j);
sItem[j]=strContents;
printf("%s\t",sItem[j]);
}
printf("\n");
if(!InsertExcel(sItem[1],sItem[2]))
{
::MessageBox(NULL,"导入数据出错","错误",MB_OK);
return;
