C # code database connection Configuration Interface __ Database

Used to do WinForm program, incredibly special to do an interface to configure the connection string. Today accidentally discovered: unexpectedly can call the configuration interface in the vs.net2005 directly to handle. The use of methods is also simple: first, add reference C:/Program Files/microsoft Visual Studio 8/common7/ide/microsoft.data.connectionui.dialog.dll II, Introducing the namespace C # code using Microsoft.Data.ConnectionUI; C # code Dataconnectiondialog DLG = new Dataconnectiondialog (); Dlg. Datasources.add (Datasource.sqldatasource); Dlg. Selecteddataprovider = Dataprovider.sqldataprovider; Dataconnectiondialog.show (DLG, this); For example, in the Click event of a button, C # code private void Button1_Click (object sender, EventArgs e) {Dataconnectiondialog dlg = new Datacon Nectiondialog (); Dlg. Datasources.add (Datasource.sqldatasource); Dlg. Selecteddataprovider = Dataprovider.sqldataprovider; Dataconnectiondialog.show (DLG, this); Four, the operation of the interface out, is not quite professional! Dataconnectiondialog also has many properties that can be configured to change the appearance of the window to meet different needs.
