推荐答案

MsgBox函数将始终打开新窗口，如果不需要用户输入，您将需要其他方式来显示错误消息

MsgBox function will always open new window you will need an other way to display error message if no user input is required

你好
获得2种方法的理想结果
1.您可以创建非托管消息框
2.在另一个线程中显示消息框

我在这里展示了第二个

Hi
to get the desired results 2 ways r there
1. you can create unmanaged message box
2. show the messagebox in another thread

here i''ve shown the 2nd one

Public Class Form1

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
        Try
            ''do some work
            ''for instance I''m intentionally creating an exception
            Throw New Exception("test error message")
        Catch ex As Exception
            Dim t As New Threading.Thread(New Threading.ParameterizedThreadStart(AddressOf shoMsg))
            t.Start(ex)
        End Try
        
    End Sub

    Private Sub shoMsg(ex As Exception)
        MessageBox.Show(ex.Message)
    End Sub
End Class

如果使用自定义对话框显示错误，请使用ShowDialog()调用而不是Show()来显示错误.在显示错误时，这将使您无法访问表单.如果您使用内置的MessageBox对象，那么它将自动成为模态对象.

If you are using a custom dialog to show the error, then use the ShowDialog() call instead of the Show() call to display it. That will make your form inaccessible while the error is being displayed. If you use the built in MessageBox object, then it automatically will be modal.
