ADODC控件为ACCESS数据库建立新表的一种方法
1、添加ADODC到窗体
2、ACESS数据库中至少有一张表存在。
Private Sub Form_Load()
Adodc1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
"C:\Documents and Settings\Administrator\" & _
"My Documents\11.mdb;Persist Security Info=False"
Adodc1.CommandType = adCmdUnknown
Adodc1.RecordSource = "select top 1 * from tb11"
Adodc1.Refresh
With Adodc1.Recordset.ActiveConnection
.Execute = "CREATE TABLE [NT_channel_product3]([Id] counter CONSTRAINT id PRIMARY KEY," & _
"[ChID] long NOT NULL ,title text(100) NOT NULL ,[ClassID] long NOT NULL ," & _
"[SpecialID] text (200) NULL ,[TitleColor] text (10) NULL ," & _
"[TitleITF] byte NULL ,[TitleBTF] byte NULL ,[PicURL] text (200) NULL ," & _
"[Content] memo NULL ,[NaviContent] text (200) NULL ," & _
"[ContentProperty] text (9) NULL ,[Author] text (100) NULL ," & _
"[EdITor] text (50) NULL ,[Souce] text (100) NULL ,[OrderID] byte NOT NULL ," & _
"[Tags] text (100) NULL ,[Templet] text (200) NULL ," & _
"[SavePath] text (200) NULL ,[FileName] text (100) NULL ," & _
"[isDelPoint] byte NOT NULL ,[Gpoint] long NULL ,[iPoint] long NULL ," & _
"[GroupNumber] memo NULL ,[Metakeywords] text (200) NULL ," & _
"[Metadesc] text (200) NULL ,[Click] long NULL ," & _
"[CreatTime] datetime NULL ,[isHTML] byte NOT NULL ," & _
"[isConstr] byte NOT NULL ,[ConstrTF] byte NOT NULL)"
End With
End Sub

窗体中的代码：
Private Sub ComboBox1_Change()
Dim cn As Object, sql$, arr, i&
Set cn = CreateObject("adodb.connection")

有三种办法
第一种是用access的JDBC驱动程序，到http://industry.java.sun.com/products/jdbc/drivers这个网站上查找并下在access的jdbc驱动程序。
第二个办法是你用下面的代码试试
con = DriverManager.getConnection("jdbc:odbc:Dri ......
SQL:
using System.Data.SqlClient;
string sql = "server=.;uid=sa;pwd=;database=tablename;";
ACCESS:
using System.Data.OleDb;
string sql = "PROVIDER=Microsoft.Jet.OLEDB.4.0;DATA Source=" + HttpRuntime.AppDomainAppPath + "//App_Data//db.mdb";
HttpRuntime.AppDomainAppPath 为根目录
