利用Delphi 5中调用Excel 97
--------------------------------------------------------------------------------

---- 在Delphi 5中简单地封装了一组Microsoft Office自动化对象(Automation servers)。它使得我们很容易地把Office中的应用程序(Word, Excel, PowerPoint, Outlook and Access等)当作一个com应用服务器进行控制。在Delphi 5中已经带了Word与PowerPoint的例子,因为Excel的调用与这两个应用服务器的调用略有不同,所以本人根据这两个例子写了个Excel 97的简单例子以供参考。
---- 步聚
创建一个普通Application。
在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet。
连接Excel 97,具体方法如下:
打开Excel97。
Try
ExcelApplication1.Connect;
Except
End;
ExcelApplication1.Visible[0]:=True;
增加一个Workbook。
ExcelWorkbook1.ConnectTo(ExcelApplication1.Workbooks.Add(EmptyParam,0));
添加一个Worksheet。
var
Temp_Worksheet: _WorkSheet;
begin
Try
Temp_Worksheet:=ExcelWorkbook1.WorkSheets.Add(EmptyParam,EmptyParam,
EmptyParam,EmptyParam,0) as _WorkSheet;//(注意)
ExcelWorkSheet1.ConnectTo(Temp_WorkSheet);
Except
ShowMessage('Failure');
End;
end;
关闭Excel.
Try
ExcelApplication1.Quit;
ExcelWorksheet1.Disconnect;
ExcelWorkbook1.Disconnect;
ExcelApplication1.Disconnect;
Except
End;
---- 4. 对Excel的一些操作:
选择当前Workbook的某一Worksheet.
procedure TForm1.ComboBox1DropDown
(Sender: TObject);
var
i: Integer;
begin
ComboBox1.Clear;
For i:=1 to ExcelWorkbook1.Worksheets.Count do
ComboBox1.Items.Add((ExcelWorkbook1.Worksheets.Item as _WorkSheet).Name);
end;
procedure TForm1.ComboBox1Change
(Sender: TObject);
begin
ExcelWorkSheet1.ConnectTo(ExcelWorkbook1.Worksheets.Item [ComboBox1.ItemIndex+1]
as _WorkSheet);
ExcelWorkSheet1.Activate;
end;
选择某一Workbook:
procedure TForm1.ComboBox2DropDown
(Sender: TObject);
var
i: Integer;
begin
ComboBox2.Clear;
if ExcelApplication1.Workbooks.Count >0 then
For i:=1 to ExcelApplication1.Workbooks.Count do
Combobox2.Items.Add(ExcelApplication1.Workbooks.Item.Name);
end;
procedure TForm1.ComboBox2Change(Sender: TObject);
begin
ExcelWorkSheet1.Disconnect;
ExcelWorkBook1.ConnectTo(ExcelApplication1.Workbooks.Item[Combobox2.ItemIndex+1]);
ExcelWorkBook1.Activate;
ExcelWorksheet1.ConnectTo(ExcelWorkBook1.ActiveSheet as _WorkSheet);
ExcelWorkSheet1.Activate;
end;
对某一单元格进行赋值及取值。
procedure TForm1.Button5Click(Sender: TObject);
begin
ExcelWorksheet1.Cells.Item[SpinEdit2.Value,SpinEdit1.Value]:=Edit1.Text;
end;
procedure TForm1.Button6Click(Sender: TObject);
begin
Edit1.Text:=ExcelWorksheet1.Cells.Item[SpinEdit2.Value,SpinEdit1.Value];
end;
选择某一区域
ExcelWorkSheet1.Range['A1','C1'].Select;
打开一个Excel文件。
if OpenDialog1.Execute then
Begin
Try
ExcelWorkBook1.ConnectTo(ExcelApplication1.Workbooks.Open(OpenDialog1.FileName,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,
EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,EmptyParam,0));
ExcelWorkSheet1.ConnectTo(ExcelWorkBook1.Activesheet as _Worksheet);
Except;
End;
End;
