Use Delphi 5 to transfer Excel 97
---- Simply encapsulate a group of Microsoft Office Automation objects in Delphi 5. It makes it easy for us to control the applications in Office (Word, Excel, PowerPoint, Outlook and Access, etc.) as a COM application server. In Delphi 5, you already have an example of Word and PowerPoint, because Excel calls are slightly different from the call of the two application servers, so I write a simple example of Excel 97 based on the two examples for reference.
---- Step together
1. Create a normal Application.
2. Put EXCELAPPLICATION, Excelworkbook, and Excelworksheet in Form.
3. Connect Excel 97, the specific method is as follows:
Open Excel97.
Try
Excelapplication1.connect;
Except
END;
Excelapplication1.visible [0]: = true;
Add a Workbook.
Excelworkbook1.connectto (ExceLapplication1.
Workbooks.add (EmptyParam, 0));
Add a Worksheet.
VAR
Temp_Worksheet: _Worksheet;
Begin
Try
Temp_Worksheet: = Excelworkbook1.
Worksheets.add (EmptyParam,
EMPTYPARAM, EMPTYPARAM, EMPTYPARAM, 0)
as _Worksheet; // (note)
Excelworksheet1.connectto (Temp_Worksheet);
Except
ShowMessage ('failure');
END;
END;
Close Excel.
Try
Excelapplication1.quit;
Excelworksheet1.disconnect;
Excelworkbook1.disconnect;
Excelapplication1.disconnect;
Except
END;
---- 4. Some operations to Excel:
Select a WorkSheet for Workbook.
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 [i]
as _Worksheet) .name);
END;
Procedure TFORM1.COMBOBOX1CHANGE
Sender: TOBJECT;
Begin
Excelworksheet1.connectto
(Excelworkbook1.worksheets.Item
[ComboBoX1.ItemIndex 1] as _Worksheet;
Excelworksheet1.actiVate;
END;
Select a one 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 [i] .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;
Assign a value and values for a cell.
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;
Select a certain area
Excelworksheet1.range ['A1', 'C1']. Select;
Open an Excel file.
IF openDialog1.execute the
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.activeesheet
as _Worksheet);
Except;
END;
END;
