在frmMain窗体定义
Public UserName As String
Public UserId As String
UserName="aaa"

在frmOrderList窗体中定义
Private UserName As String = ""
然后
Public Sub New(ByVal sUserName As String)
MyBase.New()

'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()

'在 InitializeComponent() 调用之后添加任何初始化
UserName = sUserName

End Sub
然后
Private Sub frmOrderList_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
txbListMaker.Text = UserName
End sub

不知道vb.net 如何引用另外一个窗体的变量，请哪位高手解答一下。Thanks

我用vb.net2005开发，可是源代码是vb.net2003的,不明白frmOrderList进货单其中代码
Public Sub New(ByVal sUserName As String)
MyBase.New()
InitializeComponent()
UserName = sUserName
End Sub

Private Sub frmOrderList_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Me.txbListMaker.Text = UserName
End sub

请帮忙看一下源代码，它是怎么样引用另外一个窗体的变量。

Thanks

已经解决呢。Thanks

在frmMain窗体定义
Public UserName As String
Public UserId As String
UserName="aaa"

Private Sub MenuItemOrderList_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MenuItemOrderList.Click
Dim childFrm As frmOrderList = New frmOrderList(UserName)
childFrm.MdiParent = Me
childFrm.Show()
End Sub

在frmOrderList窗体中定义
Private UserName As String = ""
然后
Public Sub New(ByVal sUserName As String)
MyBase.New()

'该调用是 Windows 窗体设计器所必需的。
InitializeComponent()

'在 InitializeComponent() 调用之后添加任何初始化
UserName = sUserName

End Sub
然后
Private Sub frmOrderList_Load(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
txbListMaker.Text = UserName
End sub
