Add/Delete menu at run time?

Hi,

How can I add a menu and delete a menu at run time?

An example would be appreciated..

Dan

The best way is by using the api.
(Maybe this example does what you want)

Use AppendMenu to add and RemoveMenu to remove.

Code:

---

Private Declare Function AppendMenu Lib "user32" Alias "AppendMenuA" (ByVal hMenu As Long, ByVal wFlags As Long, ByVal wIDNewItem As Long, ByVal lpNewItem As Any) As Long
Private Declare Function RemoveMenu Lib "user32" (ByVal hMenu As Long, ByVal nPosition As Long, ByVal wFlags As Long) As Long
Private Declare Function GetMenu Lib "user32" (ByVal hwnd As Long) As Long
Private Declare Function GetSubMenu Lib "user32" (ByVal hMenu As Long, ByVal nPos As Long) As Long
Private Const MF_BYPOSITION = &H400&

Private Sub Command1_Click()
    'Add a menu
    AppendMenu GetSubMenu(GetMenu(hwnd), 0), MF_BYPOSITION, 0, "New Item"
End Sub

Private Sub Command2_Click()
    'Remove a menu
    RemoveMenu GetSubMenu(GetMenu(hwnd), 0), 0, MF_BYPOSITION
End Sub

Is the only way to do it through the API?

The reason I ask is that one of the skills measured for the MCSD Certification is to be able to:

"Create an application that adds and deletes menus at run time."

I'd be really suprised if they expect you to work with the API. In fact, the course that I took did not ever talk about this subject..

Is there a way to do this entirely within VB without calling the API? I just want to be prepared for the exam.

thanks,

Dan

Simple way is to load and unload during runtime. You must have 1 menuitem at the same level present and you cant add new subitems to a menuitem.

I used this code to add submenu's with page numbering. One menuitem must be there with index 0

Code:

---

Public Sub procSetPageNr()
    On Error Resume Next
    Dim giCounter as Integer
    'clear excisting pages
    If mnuGoBarToPageNr.Count > 1 Then
        For giCounter = mnuGoBarToPageNr.Count To 1
          Unload frmMain.mnuGoBarToPageNr(giCounter)
        Next giCounter
    End If
    'ad new items
    For giCounter = 2 To giPageCounter
        Load frmMain.mnuGoBarToPageNr(giCounter)
        mnuGoBarToPageNr(giCounter).Visible = True
        mnuGoBarToPageNr(giCounter).Caption = "Page" & giCounter
    Next giCounter
End Sub

It's no good this way, API code is much better but probably not what you need to know for your course.
