<br>主题：关于验证控件
<br>内容：private void btnSubmit_Click(object sender, System.EventArgs e)<BR>{<BR>string constr=@&#34;Provider=Microsoft.Jet.OLEDB.4.0;<BR>Data Source=C:\Inetpub\wwwroot\SampleDatabase\db1.mdb;&#34;;<BR><BR>OleDbDataAdapter adapter = new OleDbDataAdapter();<BR>DataSet myds = new DataSet();<BR>OleDbConnection myConn = new OleDbConnection(constr);<BR><BR>try<BR>{<BR>myConn.Open();<BR>adapter.SelectCommand =new OleDbCommand(&#34;SELECT * FROM Logon WHERE UserName = ?&#34;);<BR>adapter.SelectCommand.Parameters.Add(&#34;UserName&#34;,OleDbType.VarChar);<BR>adapter.SelectCommand.Connection = myConn;<BR>adapter.SelectCommand.Parameters[0].Value = txtUserName.Text.Trim();<BR>adapter.Fill(myds,&#34;UserDetails&#34;);<BR>if(myds.Tables[&#34;UserDetails&#34;].Rows.Count==0)<BR>{<BR>lblMessage.Text = &#34;invalid user name&#34;;<BR>}<BR>else<BR>{<BR>if(myds.Tables[&#34;UserDetails&#34;].Rows[0][1].ToString()==txtPassword.Text)<BR>lblMessage.Text = &#34;Hello: &#34;+txtUserName.Text;<BR>else<BR>lblMessage.Text = &#34;Invalid password!&#34;;<BR>}<BR>}<BR>catch <BR>{<BR>lblMessage.Text = &#34;Can not open database!&#34;;<BR>}<BR>finally <BR>{<BR>myConn.Close();<BR>}<BR>}<BR><BR>private void Addmem_Click(object sender, System.EventArgs e)<BR>{<BR>//RequiredFieldValidator1.Enabled = false;<BR>//RequiredFieldValidator2.Enabled = false;<BR>Response.Redirect(&#34;addmem.aspx&#34;);<BR>}<BR>}<BR>---------------------------------------------------------------------------------<BR>如上面的代码,我用的是vs的验证控件,它的enable属性是true,现在我在<BR>Addmem_Click函数重不想使用该验证,所以加了已经被注释掉的两句,但是没有用,是不是我得方法有问题,应该怎么做,高手指教!!<BR>
