我测试没有问题：1、窗口b必须是独立窗口
2、不要在窗口设计的预览中测试这个功能，会死机的
Dim tab As WinForm.TabControl = e.form.Controls("TabControl1")
Dim Name As String = "窗口B"
Dim p As WinForm.TabPage = tab.TabPages.Add(e.sender.name,e.sender.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
p.Controls.Clear
p.Controls.add(Forms(Name).BaseForm)
tab.SelectedPage = p
