怎么取消窗体！！！！
有两个窗体frmWelcome，frmLogin
frmWelcome 里有一个btnLogin ，我点击btnLogin 进入到frmLogin，我实现了这个功能。但是我不能关掉frmWelcome.我只想要我当前form只打开一个。我是在visual basic 2010 下运行。。。请大家帮我解决一下。很急的！！！！！
我的代码如下：
Public Class frmWelcome

Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
frmLogin.ShowDialog() 'show the login form
Me.Hide()
End
End Sub

Private Sub LinklblRegister_LinkClicked(ByVal sender As System.Object, ByVal e As System.Windows.Forms.LinkLabelLinkClickedEventArgs) Handles LinklblRegister.LinkClicked
frmRegister.ShowDialog() 'show the new customer register form
Me.Hide()
End Sub
End Class


我运行结果是这样：


请大家帮我看看。我是菜鸟。

[解决办法]
Private Sub btnLogin_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogin.Click
me.hide()
frmLogin.ShowDialog(vbmodal) 'show the login form
Me.Show()

End Sub
