显示表格而不会失去焦点

问题描述

我正在创建带有通知的Messenger(类似于MSN).

如何显示通知窗口，而又不会失去对活动表单的关注?

我尝试过了

I am creating a messenger with a notification(MSN like).

How Can i show a notification windows without losing my focus on my active form?

i tried this

Private Declare Function ShowWindow Lib "user32" (ByVal handle As IntPtr, ByVal nCmdShow As Integer) As Integer

Private Const SW_SHOWNA As Integer = 4

Private Sub ShowForm()
    ShowWindow(Me.Handle, SW_SHOWNA)
End Sub

还有这个

and this

Protected Overrides ReadOnly Property ShowWithoutActivation() As Boolean
        Get
            Return True
        End Get
End Property

但是它们都不起作用.

每次弹出通知窗口时，我总是会失去对活动表单的关注.

谢谢.

But none of them working.

Everytime a notification windows pop up, i always lost my focus on my active form.

Thanks.
