把其中的c:\windows\system32\cmd.exe換成你要嵌入的應(yīng)用程序
vb.net中如何加載另一個窗體到主窗體的一個控件中
你這個要求實在是不對路子。是思路不對。
應(yīng)該是將窗體一和窗體二中的控件分別用一個panel裝起來，設(shè)為隱含狀態(tài)。都放在主窗體的panel1中。
點擊 窗體一時，第一個panel的Visible=True,第二個panel的Visible=False
點擊 窗體二時，第一個panel的Visible=False,第二個panel的Visible=True
就達(dá)到你要的效果了。
窗體不能裝來裝去的。
再有一個方法就是創(chuàng)建自定義控件。那個說起來太麻煩，看看書吧。
如何給VB.NET窗體添加子窗體？
直接添加一個MID父窗體或在已有窗體的屬性中找到IsMDIContainer屬性，然后設(shè)置為True，然后創(chuàng)建第二個窗體 ，需要加載子窗體的時候：
Dim NewMDIChild As New Form2
NewMDIChild.MdiParent = Me
NewMDIChild.Show()
Public?Shared?Sub?CheckMDIChildForm(ByVal?MDIForm?As?Windows.Forms.Form,?ByVal?MDIChildForm?As?Windows.Forms.Form,?ByVal?MDIChildFormName?As?String)
If?MDIForm.MdiChildren.Length??1?Then
'如果沒有任何一個MDI子窗體，則創(chuàng)該MDI子窗體的窗體實例
Dim?MDIChildFrm?As?Windows.Forms.Form?=?MDIChildForm?'?定義MDI子窗體
MDIChildFrm.MdiParent?=?MDIForm?'指定父窗體
MDIChildFrm.Show()?'打開窗體
Exit?Sub
Else
Dim?x?As?Integer
Dim?frmyn?As?Boolean
For?x?=?0?To?(MDIForm.MdiChildren.Length)?-?1
Dim?tempChild?As?Windows.Forms.Form?=?CType(MDIForm.MdiChildren(x),?Windows.Forms.Form)
If?tempChild.Name?=?MDIChildFormName?Then
'檢測到有該MDI子窗體，設(shè)為激活?并退出循環(huán)
frmyn?=?True
tempChild.BringToFront()
Exit?For
Else
frmyn?=?False
End?If
Next
If?Not?frmyn?Then
'在打開的窗體中沒檢測到則新建
Dim?MDIChildFrm?As?Windows.Forms.Form?=?MDIChildForm?'?定義MDI子窗體
MDIChildFrm.MdiParent?=?MDIForm?'指定父窗體
MDIChildFrm.Show()?'打開窗體
End?If
End?If
End?Sub
