推荐答案

<$有什么问题c $ c> Form.Show ， Form.Hide ？

但是，我觉得您的应用程序设计中存在滥用行为，这对于尚未使用的人来说是很自然的隐藏或显示表单。有可能，你需要检查它。如果你解释为什么要这样做，你可以得到更多的帮助。







之后OP的澄清：



隐藏一个表格并展示另一个表格不是一个好主意。如果您不再使用它，为什么要隐藏一个表单。一种模式是这样的：

What's wrong with Form.Show, Form.Hide?

Here: http://msdn.microsoft.com/en-us/library/system.windows.forms.form.aspx[^].

However, I feel the abuse in your application design, which is only natural for a person who did not yet hide or show a form. Chances are, you will need to review it. You could get more help if you explain why would you do it.



After OP's clarification:

It's wasn't a good idea to hide one form and show another. Why hiding one form if you are not going to use it any longer. One pattern would be like this:

' in entry-point method (Main):
Dim mainForm As Form = New FormMain()
Dim loginForm As Form = New FormAuthentication()
' implement AuthenticationFailed property
loginForm.ShowDialog()
If loginForm.AuthenticationFailed Then
	Return
End If
' application terminates, the user can tray again
' authentication successful:
Application.Run(mainForm)

在更复杂的变体中，你可以给用户很少的尝试等等......
