对于MFC大学根本没学过,现在突然叫自己做这么强大的功能,一阵恐惧袭来。
怎么办,上网百度、谷歌了!有些事情不是自己弄不了,只是自己懒的。
CListCtrl控件导出excel大概步骤如下:
1.首先打开vs2010,建一个项目(ExportExcel),建立完后点击右键,添加--类--MFC--TypeLib中的MFC类,到该页面点添加如下:
2.点添加完后,注意下,找到相关头文件,注释红色那行
//#import "D:\\Program Files\\Microsoft Office\\OFFICE11\\EXCEL.EXE" no_namespace
// CWorkbook 包装类
class CWorkbook : public COleDispatchDriver
{
public:
CWorkbook(){} // 调用 COleDispatchDriver 默认构造函数
CWorkbook(LPDISPATCH pDispatch) : COleDispatchDriver(pDispatch) {}
CWorkbook(const CWorkbook& dispatchSrc) : COleDispatchDriver(dispatchSrc) {}
3.注释完后,把上面添加的类的头文件加到你要实现导出excel功能的类中,如下:
#include "CApplication.h"
#include "CRange.h"
#include "CWorkbooks.h"
#include "CWorksheets.h"
#include "CWorkbook.h"
#include "CWorksheet.h"
4.实现主要代码如下:
//导出
void Cimportexcel2Dlg::OnBnClickedButton1()
{
CFileDialog FileDialog(FALSE,L"xls",NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT, _T("Microsoft Excel 2000(*.xls)|*.xls|所有文件(*.*)"),this);
if(FileDialog.DoModal()!=IDOK)
{
return;
}
CString cStrFile=FileDialog.GetPathName(); //选择保存路径名称
if(::PathFileExists(cStrFile))
DeleteFile(cStrFile);
//CString cStrFile = _T("E:\\myexcel.xls");
COleVariant covTrue((short)TRUE),covFalse((short)FALSE),covOptional((long)DISP_E_PARAMNOTFOUND,VT_ERROR);
CApplication app; //Excel程序
CWorkbooks books; //工作簿集合
CWorkbook book; //工作表
CWorksheets sheets; //工作簿集合
CWorksheet sheet; //工作表集合
CRange range; //使用区域
CoUninitialize();
book.PrintPreview(_variant_t(false));
if(CoInitialize(NULL)==S_FALSE)
{
MessageBox(L"初始化COM支持库失败!");
return;
}
if(!app.CreateDispatch(_T("Excel.Application"))); //创建IDispatch接口对象
{
//MessageBox(_T("Error!"));
}
books = app.get_Workbooks();
book = books.Add(covOptional);
sheets = book.get_Worksheets();
sheet = sheets.get_Item(COleVariant((short)1)); //得到第一个工作表
CHeaderCtrl *pmyHeaderCtrl= m_list.GetHeaderCtrl(); //获取表头
int m_cols = pmyHeaderCtrl-> GetItemCount(); //获取列数
int m_rows = m_list.GetItemCount(); //获取行数
TCHAR lpBuffer[256];
HDITEM hdi; //This structure contains information about an item in a header control. This structure has been updated to support header item images and order values.
hdi.mask = HDI_TEXT;
hdi.pszText = lpBuffer;
hdi.cchTextMax = 256;
CString colname;
CString strTemp;
int iRow,iCol;
for(iCol=0; iCol GetItem(iCol, &hdi); //获取表头每列的信息
range.put_Value2(COleVariant(hdi.pszText)); //设置每列的内容
int nWidth = m_list.GetColumnWidth(iCol)/6;
//得到第iCol+1列
range.AttachDispatch(range.get_Item(_variant_t((long)(iCol+1)),vtMissing).pdispVal,true);
//设置列宽
range.put_ColumnWidth(_variant_t((long)nWidth));
}
range = sheet.get_Range(COleVariant( _T("A1 ")), COleVariant(colname));
range.put_RowHeight(_variant_t((long)50));//设置行的高度
range.put_VerticalAlignment(COleVariant((short)-4108));//xlVAlignCenter = -4108
COleSafeArray saRet; //COleSafeArray类是用于处理任意类型和维数的数组的类
DWORD numElements[]={m_rows,m_cols}; //行列写入数组
saRet.Create(VT_BSTR, 2, numElements); //创建所需的数组
range = sheet.get_Range(COleVariant( _T("A2 ")),covOptional); //从A2开始
range = range.get_Resize(COleVariant((short)m_rows),COleVariant((short)m_cols)); //表的区域
long index[2];
for( iRow = 1; iRow <= m_rows; iRow++)//将列表内容写入EXCEL
{
for ( iCol = 1; iCol <= m_cols; iCol++)
{
index[0]=iRow-1;
index[1]=iCol-1;
CString szTemp;
szTemp=m_list.GetItemText(iRow-1,iCol-1); //取得m_list控件中的内容
BSTR bstr = szTemp.AllocSysString(); //The AllocSysString method allocates a new BSTR string that is Automation compatible
saRet.PutElement(index,bstr); //把m_list控件中的内容放入saRet
SysFreeString(bstr);
}
}
range.put_Value2(COleVariant(saRet)); //将得到的数据的saRet数组值放入表格
book.SaveCopyAs(COleVariant(cStrFile)); //保存到cStrFile文件
book.put_Saved(true);
books.Close();
//
book.ReleaseDispatch();
books.ReleaseDispatch();
app.ReleaseDispatch();
app.Quit();
}
5.添加完,代码编译会出现错误,修改:双击提示,在DialogBox()前加下划线,就可以了
6.重新编译,OK
自己记录下步骤!oh,yeah.
按以上六个步骤,就可以实现导出了,以上代码片段网上有比较多,大家可以百度谷歌。需要代码的留邮箱!
