加载事件后的 VB.NET .NET？

Question

我需要某种方式知道表单何时完成加载。我的理由是我有第二个表单，当这个表单加载时会加载。从 form1.load 调用此代码.
Form2当前显示在 form1 后面正如我所猜测的 form1在加载结束时调用 activate 或类似的方法，因此任何 Activate、BringToFront 等都会调用 form2被覆盖。

如果您查看下面的代码，我尝试添加 frmAllocationSearch.Activate , frmAllocationSearch.BringToFront和 Me.SendToBack调用 ShowAlloactionSearchDialog() 后，但是这些都被浪费了，因为在加载事件被触发以带来 Me 之后发生了一些事情。到前面。

代码是:

Private Sub Allocation_Load(ByVal sender As Object, ByVal e As System.EventArgs) _
                            Handles Me.Load

    ShowAlloactionSearchDialog()
End Sub

Private Sub ShowAlloactionSearchDialog()

    If frmAllocationSearch Is Nothing OrElse frmAllocationSearch.IsDisposed Then
        frmAllocationSearch = New AllocationSearch
        frmAllocationSearch.MdiParent = Me.MdiParent
        frmAllocationSearch.Info = Me.Info
        frmAllocationSearch.Top = Me.Top
        frmAllocationSearch.Left = Me.Left + Me.Width - frmAllocationSearch.Width
        frmAllocationSearch.AllocationWindow = Me

        frmAllocationSearch.Show()
    Else
        If frmAllocationSearch.WindowState = FormWindowState.Minimized Then
            frmAllocationSearch.WindowState = FormWindowState.Normal
        End IF
        frmAllocationSearch.Activate()
    End If
End Sub

也许你可以试试Form.Activated事件。

Occurs when the form is activated in code or by the user.
