【VC控制EXCEL的基本操作之设置篇】
1 设置单元格的值

3 设置单元格类型
range.AttachDispatch(sheet.GetCells(),TRUE);//加载所有单元格 range.SetNumberFormat(COleVariant(L"@")); //将单元格设置为文本类型
4 设置单元格字体
Font ft; //设置第一列的字体 range.AttachDispatch(sheet.GetColumns(),true); range.AttachDispatch(range.GetItem(COleVariant((long)1),vtMissing).pdispVal,TRUE); //字体作用范围 ft.AttachDispatch(range.GetFont()); ft.SetName(COleVariant(_T("宋体"))); ft.SetSize(COleVariant((long)48)); ft.SetBold(COleVariant((long)1));//粗体 ft.SetColorIndex(COleVariant((long)2));//设置字体颜色
5 设置单元格背景色
range.AttachDispatch(sheet.GetRange(COleVariant(_T("A1")),COleVariant(_T("D1")))); //////////////设置底色///////////////// Interior it; it.AttachDispatch(range.GetInterior()); it.SetColorIndex(COleVariant((long)11));//标题底色 ////表格内容的底色//// range.AttachDispatch(sheet.GetRange(COleVariant(_T("A2")),COleVariant(_T("D5")))); it.AttachDispatch(range.GetInterior()); it.SetColorIndex(COleVariant((long)15));
6 设置表格边框
1) range.AttachDispatch(sheet.GetRange(COleVariant(_T("A2")),COleVariant(_T("D5")))); //LineStyle=线型Weight=线宽ColorIndex=线的颜色(-4105为自动) range.BorderAround(COleVariant((long)1),(long)2,((long)-4105),vtMissing);//设置边框 2) range.AttachDispatch(sheet.GetRange(COleVariant(_T("A2")),COleVariant(_T("D5")))); _variant_t v1; //线型 _variant_t v2; //宽度 _variant_t v3; //颜色 v1.vt=VT_I2; v1.lVal=2; // 线的样式:- no line; 1-solid; 2-big dot;3-small dot;4-dash dot; 5-dash dot dot; v2.vt=v1.vt; v2.lVal=3; // 线的粗细程度 v3.vt=v1.vt; v3.lVal=1; // 1-black;2-white;3-red;4-green;5-blue; 6-yellow; 7-pink;8-dark blue; UnitRge.BorderAround(v1,v2,v3,vtMissing);//设置边框

//选择A2单元格,插入一个公式"=RAND()*100000",并设置A2数字格式为货币形式 range=sheet.GetRange(COleVariant(L"A2"),COleVariant(L"A2")); range.SetFormula(COleVariant(L"=RAND()*100000")); range.SetNumberFormat(COleVariant(L"$0.00"));
10 在单元格中插入图片
Shapes shapes = sheet.GetShapes();// 从Sheet对象上获得一个Shapes range.AttachDispatch(sheet.GetRange(COleVariant(L"E5"),COleVariant(L"E5"))); // 获得Range对象,用来插入图片 shapes.AddPicture( L"d:\\pic.bmp " , false , true , (float)range.GetLeft().dblVal ,(float)range.GetTop().dblVal,(float)range.GetWidth().dblVal,(float)range.GetHeight().dblVal); ShapeRange sRange = shapes.GetRange(_variant_t(long(1))); sRange.SetHeight(float(30)); //在RANGE范围内 设置图片宽高 sRange.SetWidth(float(30));
11 对选取的区域进行排序
#define xlAscending (long) 1 #define xlDescending (long) 2 #define vOpt COleVariant((long) DISP_E_PARAMNOTFOUND, VT_ERROR) #define xlHeader (long) 1 // 选取的区域有标题 #define xlNoHeader (long) 2 // 选取的区域无标题 一定要正确确定是否有标题,否则排序可能不成功 #define xlMatchCase COleVariant((long) 1) #define xlIgnoreCase COleVariant((long) 0) #define xlTopToBottom (long) 1 // 垂直方向进行排序 #define xlLeftToRight (long) 2 // 水平方向进行排序 #define xlPinYin (long) 1 // this is the default // 按字符的中文拼音进行排序 #define xlStroke (long) 2 // 按每个字符中的笔画数进行排序 VARIANT key1; // these lines set up first arg (key1) to sort V_VT(&key1) = VT_DISPATCH; // 排序时,关键字的vt设置为VT_DISPATCH V_DISPATCH(&key1) = sheet.GetRange(COleVariant(L"A1"),COleVariant(L"A1")); // 设置按哪个关键字进行排序 选择单元意为:按此列(或行)为主关键字进行排序 range=sheet.GetRange(COleVariant(L"A1"),COleVariant(CellName)); // 选择对哪些区域内的单元格进行排序 range.Sort(key1, xlAscending, vOpt, vOpt, xlAscending, vOpt,xlAscending,xlNoHeader,vOpt,xlIgnoreCase,xlTopToBottom,xlPinYin); //设置排序 无标题时一定要设置为xlNoHeader 否则不起作用
