创建基于对话框的MFC程序
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“MicrosoftExcel 14.0 Object Library<1.7>”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,六个类被添加了进来。
分别将加进来的六个头文件上面的“#import "C:\\ProgramFiles\\Microsoft Office\\OFFICE11\\EXCEL.EXE" no_namespace”注释掉。
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 "CWorksheet.h" #include "CWorksheets.h"
…\crange.h(335): warningC4003: “DialogBoxW”宏的实参不足
…\crange.h(335): errorC2059: 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“DialogBox()”前面加“_”下划线,即“_DialogBox()”,这样就可以编译成功了。
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||"),AfxGetMainWnd()); 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.AttachDispatch(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(); } }
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 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(covOptional),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!" range = 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 = sheet.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(); }
//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"),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.InsertItem(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), 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!")); exit(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.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(sText[num])); } else { range.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(strFile)); book.put_Saved(true); app.put_Visible(true); //释放对象 range.ReleaseDispatch(); sheet.ReleaseDispatch(); sheets.ReleaseDispatch(); book.ReleaseDispatch(); books.ReleaseDispatch(); app.ReleaseDispatch(); app.Quit(); }
按【打开】按钮,出现打开对话框,可选择Excel打开。
按【写入】按钮,打开Excel文件。
按下【写入列表】,打开Excel文件。
