主题：求助：新建一窗体，放置面板1，另建一窗体 如何在主窗体启动的时候自动在面板1加载子窗体呢？

设计窗口是模式的，预览当然会死机哦！

在你打开窗口时判断一下，如果不是独立窗口，就不用

If e.Form.FormStyle = 2 Then
    Dim PB As WinForm.Panel = e.Form.Controls("Panel1")
    Dim Name As String = e.Link.Name
    Forms(Name).OPEN(-1000,-1500)
    Forms(Name).BaseForm.TopLevel = False
    Forms(Name).BaseForm.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None
    Forms(Name).BaseForm.Dock = System.Windows.Forms.DockStyle.Fill
   
    PB.BaseControl.Controls.Clear
    PB.BaseControl.Controls.add(Forms(Name).BaseForm)
End If
