网学网为广大网友收集整理了，COM组件弹出数据库连接对话框，希望对大家有所帮助！
今天查SQL Server帮助文件时，刚好点击到Using the OLE DB Connection Dialog Box页面。
Using the OLE DB Connection Dialog Box
OLE DB specifies that each provider must provide a dialog box for defining connections to its data sources. Microsoft® SQL Server™ 2000 Analysis Services complies with this requirement by providing a dialog box that enables the client application to connect to an Analysis server or a local cube.
To use this prompt, the Prompt property of the connection string must be set to 1:
Dim Conn As New ADODB.Connection
Conn.Open "Provider=msolap; Prompt=1;"呵呵，顺手到.Net下来试试，发现在OleDb下可以使用，OleDbConnection cn = new OleDbConnection( "Provider=SQLOLEDB.1; Prompt=1" );弹出
将Provider改为Microsoft.Jet.OLEDB.4.0后，显示这样的呵呵，其他的Provider就没试了。SQLConnection下面就不可以使用这种方法。这个方法有两个不好的地方：1. 弹出的对话框是非模态的；2. 只要点击取消就会抛出异常；
