VC2010对Excel的操作

1、VC2010对Excel的操作1. 创建新的C+工程创建基于对话框的MFC程序2. 添加库、添加Excel类库在工程名上右键，选择“添加”“类”（或者点击菜单栏的“项目”->“添加类”），选择“TypeLib中的MFC类”（MFC Class From TypeLib）类来源选“注册表”，在可用的类型库中选择“Microsoft Excel 11.0 Object Library<1.5>”在接口列表框中选择需要的类，在此，我们选择_Application,_Workbook,Worksheet,Range,Workbooks,Worksheets这六个就可以了。可以看到，六

2、个类被添加了进来。3. 修改头文件分别将加进来的六个头文件上面的“#import "C:Program FilesMicrosoft OfficeOFFICE11EXCEL.EXE" no_namespace”注释掉。4. 添加头文件在stdAfx.h头文件中添加加进来的这几个头文件#include "CApplication.h"#include "CRange.h"#include "CWorkbook.h"#include "CWorkbooks.h"#include "CWor

3、ksheet.h"#include "CWorksheets.h"5. 修改错误编译，会出现两个错误：crange.h(335): warning C4003: “DialogBoxW”宏的实参不足crange.h(335): error C2059: 语法错误:“,”双击错误提示，定位在错误行，VARIANT DialogBox()VARIANT result;InvokeHelper(0xf5, DISPATCH_METHOD, VT_VARIANT, (void*)&result, NULL);return result;将该函数名“DialogBo

4、x()”前面加“_”下划线，即“_DialogBox()”，这样就可以编译成功了。6. 在对话框中添加一个编辑框，并为其关联一CEdit类型变量m_Path，添加“打开”按钮，实现打开一已经存在的Excel文件。并将路径显示在编辑框中。实现代码如下。void CExportToExcelDlg:OnBnClickedButtonOpen()CFileDialog file(TRUE,NULL,NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,_T("EXCEL文件t(*.xls;*.xlsx)|*.xls;*.xlsx|"),AfxGetM

5、ainWnd();if(file.DoModal()=IDOK)CString strPath=file.GetPathName();m_Path.SetWindowTextW(strPath);CApplication app;CWorkbook book;CWorkbooks books;if (!app.CreateDispatch(_T("Excel.Application")MessageBox(_T("Error!Creat Excel Application Server Faile!");exit(1);/books.AttachDisp

6、atch(app.get_Workbooks(),true);/book.AttachDispatch(books.Add(_variant_t(strPath);books = app.get_Workbooks();book = books.Add(_variant_t(strPath);app.put_Visible(true);/结尾，释放book.ReleaseDispatch(); books.ReleaseDispatch(); app.ReleaseDispatch();app.Quit();7. 在对话框中添加“写入”按钮，实现新建一Excel文件（存在则覆盖），并向文件中写

7、入数据。实现代码如下。void CExportToExcelDlg:OnBnClickedButtonWrite()CString strFile = _T("D:WriteToExcelTest.xlsx");COleVariant covTrue(short)TRUE), covFalse(short)FALSE), covOptional(long)DISP_E_PARAMNOTFOUND, VT_ERROR); CApplication app;CWorkbook book;CWorkbooks books;CWorksheet sheet;CWorksheets

8、sheets;CRange range;CFont font;if (!app.CreateDispatch(_T("Excel.Application")MessageBox(_T("Error!Creat Excel Application Server Faile!");books = app.get_Workbooks();/books.AttachDispatch(app.get_Workbooks();可代替上面一行book = books.Add(covOptional);/book.AttachDispatch(books.Add(cov

9、Optional),true); 可代替上面一行sheets=book.get_Worksheets();/sheets.AttachDispatch(book.get_Worksheets(),true); 可代替上面一行sheet = sheets.get_Item(COleVariant(short)1);/sheet.AttachDispatch(sheets.get_Item(_variant_t("sheet1"),true); 可代替上面一行/下面两行，是向A1中写入"Yeah!I can write data to excel!"rang

10、e = sheet.get_Range(COleVariant(_T("A1"),COleVariant(_T("A1"); range.put_Value2(COleVariant(_T("Yeah!I can write data to excel!");/下面是向第二行的前十个单元格中输入1到10，十个数字for(long i=1;i<11;i+)range.put_Item(_variant_t(long)2),_variant_t(long)i),_variant_t(long)i);/设置列宽range = shee

11、t.get_Range(COleVariant(_T("A1"),COleVariant(_T("J1");range.put_ColumnWidth(_variant_t(long)5);/显示表格app.put_Visible(TRUE);/保存book.SaveCopyAs(COleVariant(strFile); book.put_Saved(true);/结尾，释放book.ReleaseDispatch(); books.ReleaseDispatch(); app.ReleaseDispatch();app.Quit(); 8. 在对话框

12、中添加列表控件，并关联变量m_Grid，并设置显示为报表样式。在对话框中添加“写入列表”按钮，实现将对话框中已有的表写入到Excel中。实现代码如下。在初始化函数中，先初始化列表。/设置列表视图的扩展风格m_Grid.SetExtendedStyle(LVS_EX_FLATSB/扁平风格显示滚动条|LVS_EX_FULLROWSELECT/允许整行选中|LVS_EX_HEADERDRAGDROP/允许整列拖动|LVS_EX_ONECLICKACTIVATE/单击选中项|LVS_EX_GRIDLINES);/画出网格线/设置表头m_Grid.InsertColumn(0,_T("编号&

13、quot;),LVCFMT_LEFT,100,0);m_Grid.InsertColumn(1,_T("姓名"),LVCFMT_LEFT,100,1);m_Grid.InsertColumn(2,_T("所属部门"),LVCFMT_LEFT,100,2);/向列表中插入数据int count = 0;m_Grid.InsertItem(count,_T("001");m_Grid.SetItemText(count,1,_T("张一");m_Grid.SetItemText(count+,2,_T("销售

14、部");m_Grid.InsertItem(count,_T("002");m_Grid.SetItemText(count,1,_T("列二");m_Grid.SetItemText(count+,2,_T("研发部");m_Grid.InsertItem(count,_T("003");m_Grid.SetItemText(count,1,_T("宇三");m_Grid.SetItemText(count+,2,_T("采购部");m_Grid.InsertIt

15、em(count,_T("004");m_Grid.SetItemText(count,1,_T("宙四");m_Grid.SetItemText(count,2,_T("宣传部");再编写按钮的响应函数void CExportToExcelDlg:OnBnClickedButtonWritelist()/ TODO: 在此添加控件通知处理程序代码CString strFile = _T("D:WriteListToExcelTest.xlsx");COleVariant covTrue(short)TRUE),

16、covFalse(short)FALSE), covOptional(long)DISP_E_PARAMNOTFOUND, VT_ERROR); CApplication app;CWorkbook book;CWorkbooks books;CWorksheet sheet;CWorksheets sheets;CRange range;if (!app.CreateDispatch(_T("Excel.Application")MessageBox(_T("Error!Creat Excel Application Server Faile!");e

17、xit(1);books = app.get_Workbooks();book = books.Add(covOptional);sheets = book.get_Worksheets();sheet = sheets.get_Item(COleVariant(short)1);/得到全部Cells range.AttachDispatch(sheet.get_Cells(); CString sText=_T("编号"),_T("姓名"),_T("所属部门");for (int setnum=0;setnum<m_Grid.

18、GetItemCount()+1;setnum+)for (int num=0;num<3;num+)if (!setnum)range.put_Item(_variant_t(long)(setnum+1),_variant_t(long)(num+1),_variant_t(sTextnum);elserange.put_Item(_variant_t(long)(setnum+1),_variant_t(long)(num+1),_variant_t(m_Grid.GetItemText(setnum-1,num);/保存book.SaveCopyAs(COleVariant(strFil
