[求助]mapx+vb开发数据绑定的问题，请高手指点呀！

<P><B>我想把数据库绑定到.gst格式地图的其中一个图层中，用的是VB语言，试图用两种方案：</B></P>
<P><B>（一）：</B></P>
<P><B>Dim ds As Dataset
Dim db As Database
Dim rs As Recordset
Set db = DBEngine.Workspaces(0).OpenDatabase("C:\Program Files\Microsoft Visual Studio\VB98\diming.mdb")
    Set rs = db.OpenRecordset("jinan")
    Set ds = Map1.DataSets.Add(miDataSetADO, Adodc1.Recordset, "MyDataset")</B></P>
<P><B>其中“diming.mdb”是需要挂接的数据库名，“jinan”是其下的表名，Adodc1是添加的adodc控件。</B></P>
<P><B>运行时“Set db = DBEngine.Workspaces(0).OpenDatabase("C:\Program Files\Microsoft Visual Studio\VB98\diming.mdb")”一行显示错误：
Run-time error‘3343’：
Unrecognized database format"C:\Program Files\Microsoft Visual Studio\VB98\diming.mdb".</B></P>
<P><B>帮助文件显示：
Possible causes:
1.The specified file name is not a Microsoft Jet database.
2.The specified file name is a device name, such as a printer, a console, and so forth.
3.The .mdb file has invalid header information or an unknown sort order.
4.A commit is pending from another user, but the lock file cannot be found.
5.During a commit, you are attempting to write a Long value larger than the 2K maximum page size.
6.The database is damaged. Repair and compact the database, and then try opening it again.</B></P>
<P><B>第二种方案：</B></P>
<P><B>Dim MyDataset As Dataset
      
    Set MyDataset = Map1.DataSets.Add(miDataSetADO, Adodc1.Recordset, "MyDataset")</B></P>
<P><B>其中Adodc1控件已在其属性设置中与所需挂接的数据库连接成功。</B></P>
<P><B>运行时“Set MyDataset = Map1.DataSets.Add(miDataSetADO, Adodc1.Recordset, "MyDataset")”一行显示出错信息：</B></P>
<P><B>Run-time error‘1164’：
The specified source is not an ADO recordset object.</B></P>
<P><B>两种方案看起来都没什么问题，可就是不行，求求那位高手指点指点，我都快急疯了。
</B></P>

应该是你连接数据库的方式不正确，你看看ADO的资料。

<P>你是 用ACCESS的吗</P>

<P><B>Dim ds As Dataset<BR>Dim db As Database<BR>Dim rs As Recordset<BR>Set db = DBEngine.Workspaces(0).OpenDatabase("C:\Program Files\Microsoft Visual Studio\VB98\diming.mdb")<BR>    Set rs = db.OpenRecordset("jinan")<BR>    Set ds = Map1.DataSets.Add(miDataSetADO, Adodc1.Recordset, "MyDataset")</B></P>
<P><STRONG>miDataSetADO有问题</STRONG></P>
<P><STRONG>这个例子不是用的ADO</STRONG></P>
<P><STRONG>是DAO</STRONG></P>

<P>你写的也太麻烦了，而且还用DAO很累人的</P>
<P>我现在网吧，没办法给你写语句，你留言我发给你.</P>

<P>我两个月前就已经做完毕业设计了。你知道怎么解决么？我的邮箱<a href="mailtzj09162001@sohu.com" target="_blank" >zj09162001@sohu.com</A>,如果你知道的话可以发给我么，我还想看一看，谢谢了</P>
