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
到
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!
