问题描述

你好,



我有一个密码框的代码,当用户点击它时,我希望删除文本密码和/或要使用的密码字符。

Hello,

I have the following code for a password box and when the user clicks it, I'd like for the text "Password" to be removed and a password character to be used.

Private Sub TextBox2_GotFocus(sender As Object, e As EventArgs) Handles TextBox2.GotFocus
       With TextBox2
           If .Text = "Password" Then
               .Text = Nothing
               .ForeColor = Color.Black
               .UseSystemPasswordChar = True
           End If
       End With
   End Sub





每当我点击textbox2时,我都会收到错误





Whenever I click textbox2, I get the error

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in System.Windows.Forms.dll

Additional information: Error creating window handle.





就行



on the line

.UseSystePasswordChar = True





我不知道为什么会发生这种情况,因为我以前从未遇到过这种情况。

如何才能完成这项工作?

推荐答案

我只是通过查看一条线并感到一切可疑而得到了它。我更改了行



如果.Text =密码那么







如果.UseSystemPasswordChar = False那么



我不知道它为什么会起作用但确实如此!
I got it working just by looking at a line and feeling all suspicious about it. I changed the line

If .Text = "Password" Then

to

If .UseSystemPasswordChar = False Then

I have no idea why it works but it does!
