要用DELPHI中的ADOpd控g讉KExcel数据文gQ首先应该徏立一些基本概c(din)你需要将一个Excel数据文g惌
Z个关pL据库QExcel文g中的每个工作表就对应该数据库中的一个表Q而工作表中的每一列当然就是表的列?jin)?br />然后Q按照下列面的秘诀q行可以?br />
1.讄ADOConnection的ConnectionString
构造ConnectionStringӞOLE DB的提供者要选择Microsoft Jet 4.0 OLE DB Provider作ؓ(f)ADO的驱动程序?br />q本来是用于q接Access数据库的驱动E序Q但也可打开Excel文g?br />q接的数据库名称当然是你要打开的Excel文gQ注意扩展名?.xlsQ而不?.mdb?br />最关键的一Ҏ(gu)Q还要设|扩展属性Extended Properties?Excel 8.0"Q否则，试q接时会(x)报告无法识别数据格式
的错误。Extended Properties的属性值在"所?参数中输入?br />最后，讄完成后的ConnectionString中的各项参数为：(x)

Persist Security Info=False
2.讄ADODataSet或ADOTable

q接DBF数据
构造ado connection string
提供者选择 Microsoft Jet 4.0 OLEDB Provider
"所?那里~辑 Extended PropertiesQ?br />dbf文g的话讄为dBase 5.0Q注意dBase?.0之间必须有空|最好拷贝过ȝ_(d)(j)
db文g的话讄为Paradox 7.X
Qdbf是dbase或Vfox数据库，db是paradox数据库）(j)
"q接"那里?数据库名U?输入的是目录名，不能包含文g名，
比如你的文g?c:tempaaa.dbf Q那么输入c:temp
同时CursorLocation 讄为：(x) clUseServer
q可?
如果直接q的话，ADO的连接字串设为：(x)
adoConnection1.ConnectionString:='Provider=MSDASQL.1;Extended Properties="Driver={Microsoft Visual Foxpro Driver};SourceType=DBF;SourceDB=c:mydb"';
如果是用ODBCQ先在ODBC中设一个DSNq接到该DBF库，然后Q在ADOConnection中设|连接ODBC的连接字串即?可以用向导帮助完?

If you check out the C:\Windows\system32\LogFiles\HTTPERR\httperr*.log files on the distribution server, you'll likely see either Timer_MinBytesPerSecond errors or Timer_ConnectionIdle errors. These are caused by IIS' default settings, contained within its metabase, which define the minimum traffic flow rate for a connection to be kept alive and the maximum idle time allowed before a connection is dropped. For some reason, SUS servers seem to take their good old time while downloading updates, and these parameters are exceeded and the distribution server drops 'em.
1) From IIS Manager, right click on the Internet Information Server (IIS) Manager root level folder and go to Properties. Check the box to enable direct metabase editing. Click OK.
2) Open the C:\Windows\system32\inetsrv\Me-taBase.xml file in Notepad. Do a search for "MinFileBytesPerSec". Change the setting for MinFileBytesPerSec from 240 to 0. Do another search, this time for "ConnectionTimeout" to be 600. Save changes and exit.
3) Restart the IIS Admin service to effect the changes.
