Question

偶尔，我会以某种方式获得在asp.net web app中注册两次的用户。注册使用createUserwizard，用户和电子邮件设置为唯一，所以我没有任何线索，没有运气在另一篇文章中获得答案，所以我已经转移到另一种方式来解决这个问题。我想可能是来自用户点击“注册”＆＃39;按钮两次靠近在一起。我一直在尝试许多解决方案，要么在点击后禁用按钮（这是字段验证的艰难b / c），要么弹出一个不说＆＃34;创建用户＆＃39;，或者甚至只是将按钮文本更改为＆＃39;创建＆＃39;，像这样solution --with no luck (Rory's)。我没有得到这个错误，但没有按钮更改发生。这是我的向导（拿出EUA，chk box pass提示）

任何防止这次x2点击的帮助都会非常感激 - 当我得到＆＃34; [user]键已经存在时，它会一直打破我使用asp控制台工具的能力＆＃34;错误。

点击一次后可以禁用按钮吗？

Public Class _Default
    Inherits Page
    Protected Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Button1.Enabled = False
        MsgBox("Next time you click, the button is disabled, and you don't get this message.")
    End Sub
End Class

阻止用户在createUserWizard上单击两次
