下面的这段代码将Picture1的图形作为菜单项。
    首先建立一个模块,并加入下面的语句。
    Declare Function GetMenu Lib "user32" _
    (ByVal hwnd As Long) As Long
    Declare Function GetSubMenu Lib "user32" _
    (ByVal hMenu As Long, ByVal nPos As Long) As Long
    Declare Function GetMenuItemID Lib "user32" _
    (ByVal hMenu As Long, ByVal nPos As Long) As Long
    Declare Function SetMenuItemBitmaps Lib "user32" _
    (ByVal hMenu As Long, ByVal nPosition As Long, _
    ByVal wFlags As Long, ByVal hBitmapUnchecked As Long, _
    ByVal hBitmapChecked As Long) As Long

    Public Const MF_BITMAP = &H4&

    Type MENUITEMINFO
    cbSize As Long
    fMask As Long
    fType As Long
    fState As Long
    wID As Long
    hSubMenu As Long
    hbmpChecked As Long
    hbmpUnchecked As Long
    dwItemData As Long
    dwTypeData As String
    cch As Long
    End Type

    Declare Function GetMenuItemCount Lib "user32" _
    (ByVal hMenu As Long) As Long
    Declare Function GetMenuItemInfo Lib "user32" _
    Alias "GetMenuItemInfoA" (ByVal hMenu As Long, _
    ByVal un As Long, ByVal b As Boolean, _
    lpMenuItemInfo As MENUITEMINFO) As Boolean

    Public Const MIIM_ID = &H2
    Public Const MIIM_TYPE = &H10
    Public Const MFT_STRING = &H0&

form1中 ```


   Private Sub Form1_load()

    ' 获得你的菜单的句柄
    hMenu& = GetMenu(Form1.hwnd)

    ' 获得第一个子菜单的句柄
    hSubMenu& = GetSubMenu(hMenu&, 0)

    ' 获得第一个菜单项
    hID& = GetMenuItemID(hSubMenu&, 0)

    '加入位图

    SetMenuItemBitmaps hMenu&, hID&, MF_BITMAP, _
    Picture1.Picture, _
    Picture1.Picture
    End Sub
    上面的代码使菜单项为图片,如果你只希望菜单项的左边有一个小位图,而右边仍为文字。可以先在Picture1绘制图片,在利用Picture1.Print加上文字,然后用Picture1.Picture加入菜单项。
