D. The distance from the footer to the bottom is 3cm:

ExcelApplication 1。 active sheet . page setup . header margin:= 3/0.035；

E. the upper margin is 2 cm:

ExcelApplication 1。 active sheet . page setup . top margin:= 2/0.035；

F the distance between the bottom edges is 2cm:

ExcelApplication 1。 active sheet . page setup . bottom margin:= 2/0.035；

G. the distance on the left side is 2cm:

ExcelApplication 1。 active sheet . page setup . left margin:= 2/0.035；

H. 2 cm from the right:

ExcelApplication 1。 active sheet . page setup . right margin:= 2/0.035；

I. the page is horizontally centered:

ExcelApplication 1。 active sheet . page setup . center horizontally:= 2/0.035；

J. vertically centered page:

17) copy operation:

A. copy the entire worksheet:

ExcelApplication 1。 active sheet . used . range . copy；

B. copy the designated area:

ExcelApplication 1。 active sheet . Range[' a 1:E2 ']。 Copy;

C. paste from A 1 position:

excel application 1 . active sheet . range .[' a 1 ']。 PasteSpecial

D. Paste from the end of the file:

ExcelApplication 1。 active sheet . range . paste special；

18) Insert a row or column:

a.ExcelApplication 1。 ActiveSheet.Rows[2]。 Insert;

b.ExcelApplication 1。 ActiveSheet.Columns[ 1]。 Insert;

19) Delete a row or column:

a.ExcelApplication 1。 ActiveSheet.Rows[2]。 Delete;

b.ExcelApplication 1。 ActiveSheet.Columns[ 1]。 Delete;

20) print preview worksheet:

ExcelApplication 1。 ActiveSheet . PrintPreview

2 1) Print out the worksheet:

ExcelApplication 1。 ActiveSheet . PrintOut

22) Save the worksheet:

If it is not ExcelApplication 1. ActiveWorkBook. Then save it.

ExcelApplication 1。 ActiveSheet . PrintPreview

23) Save the worksheet as:

ExcelApplication 1。 Save as ('c: \ Excel \ demo1.xls');

24) Give up saving:

ExcelApplication 1。 active workbook . Saved:= True；

25) Close the workbook:

ExcelApplication 1。 Workbook. Close;

26) exit Excel:

ExcelApplication 1。 Quit;

ExcelApplication 1。 Disconnect;

(3) Control Exce2D drawing with Delphi.

Put ExcelApplication, ExcelWorkbook and ExcelWorksheet into the form respectively.

var asheet 1，achart，range:variant；

1) is selected as the first worksheet in the first workbook.

ashet 1:= excelapplication 1。 Workbook [1]. Worksheet [1];

2) Add a 2D chart

achart:= asheet 1 . chart objects . add( 100， 100，200，200)；

3) Choose the form of two-dimensional graphics.

achart . chart . charttype:= 4；

4) Assign values to two-dimensional graphics.

series:= achart . chart . series collection；

Range: =sheet 1! r2c 3:r3c 9；

series.add(range，true)；

5) Add the title of the 2D drawing.

Ahart. chart . HasTitle:= True；

Ahart. Chart.charttitle.characters.text: =' Excluding 2D charts'

6) Change the font size of 2D drawing titles.

Ahart. chart . chart title . font . size:= 6；

7) Subscript two-dimensional graph.

Ahart. Charts. Axis (xlCategory, xlPrimary). HasTitle:= True；

Ahart. Charts. Axis (XL category, XL main). Axis title. Characters.text: =' subscript description';

8) Add a left label to the 2D drawing.

Ahart. Axis of the chart (xlValue, xlPrimary). HasTitle:= True；

Ahart. Charts. Axis (xlvalue, xlprimary). Axis title. Characters.text: =' Description of the left label';

9) Add a right label to the 2D drawing.

Ahart. Axis of the chart (xlValue, xlSecondary). HasTitle:= True；

Ahart. Charts. Axis (xlvalue, xlsecondary). Axis title. Characters.text: =' Description of the right tag';

10) to change the size of the display area of two-dimensional graphics.

Ahart. chart . plot area . left:= 5；

Ahart. chart . plot area . width:= 223；

Ahart. chart . plot area . height:= 108；

1 1) marks the coordinate axis of two-dimensional graphics.

achart . chart . series collection[ 1]。 Name: =' Axis Description';

(3) Database

1. stored procedure

First execute the following stored procedure.

EXEC sp_addlinkedserver

External resources',

Jet 4.0 '，

Microsoft. Jet.OLEDB.4.0 '，

' c:\ documents and settings \ administrator \ desktop \ xinxi 3 . xls '，

Empty,

' Excel 5.0 '

EXEC sp _ addlinkedsrvlogin excel source，FALSE，NULL，NULL

Then execute the following stored procedure.

Execsp _ tables _ exexexcelsource//shows several tables.

At this time, the names of several tables will be returned (the number is consistent with the number of tables in excel).

Then you use the following sentence:

Select * from excel source ... sheet1USD.

You can find the data in excel, and then you can pour it in.

Remember to execute the following two stored procedures after import:

-EXEC sp _ droplinkedsrvlogin excel source，NULL

- EXEC sp_dropserver ExcelSource

All the above operations can be tested in the query analyzer first, and then you can write stored procedures to implement it.
