主题：如何把窗口显示在页控件上

参考

Dim tab As WinForm.TabControl = e.Form.Controls("TabControl1")
Dim Name As String = "窗口2"

tab.TabPages.Add(name,name)
Dim pb = tab.BaseControl
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.TabPages(name).Controls.Clear
PB.TabPages(name).Controls.add(Forms(Name).BaseForm)
tab.SelectedPage = tab.TabPages(name)
