最近本人做了一个小软件，送给人用了，但是我后来对程序有进行了一些改动，
想重新送给他用，但我在想是不是能做到像专业软件那样，只要升级一下就可以了，
而不用卸载——重新安装这样一个过程。有哪位高手能否介绍介绍专业软件是如何
实现升级的？

about Delphi 5.0中如何读取Excel 97文件
procedure TOfficeform.Button2Click(Sender: TObject);
var MSExcel:Variant;
i,j:Integer;
begin
SaveDialog1.Filter:='*.XLS¦*.XLS';
SaveDialog1.DefaultExt:='XLS';
if SaveDialog1.Execute then
begin
MSExcel:=CreateOLEObject('Excel.Application');
MSExcel.WorkBooks.Add;
MSExcel.Visible:=False;

Table1.First;
for i:=1 to jdo
begin

MSExcel.Cells[i,2].Value:=Table1.FieldByName('COLOR').AsString;

end;

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
1. 创建一个普通Application。
2. 在Form中分别放入ExcelApplication, ExcelWorkbook和ExcelWorksheet。
3. 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.Countdo
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.Countdo
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;

我是这么做的，判断是否旧的在运行，是，关闭，删除，把自己拷过去，如没有旧的，正常运行。
 
把一些可能升级的功能放到dll中，省级dll（更换）
 
1/通过互联网检查判断
2/下载需要的文件
3/删除自己 （另查找相关）
4/替换自己以及其他下载的文件
5/关闭自己，然后启动自己（办法也很多）

看错题目了吗？
同意爱元元的哥哥 的意见
如果主程序为MAIN。EXE
你可将子程序分为DLL 或 BPL
根据需要将DLL 或BPL 或EXE文件替换旧文件便可
