可以，参考

Dim tab As WinForm.TabControl = Forms("窗口1").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)

或者

Dim PB As WinForm.Panel = e.Form.Controls("Panel2")

Dim Name As String = "工具栏"

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)
