首先设计好你的菜单
然后在窗体上加入一个按钮
代码如下:
Option Explicit
Private Declare Function GetMenuItemCount Lib "user32" (ByVal hMenu As Long) As Long
Private Const MIM_BACKGROUND As Long = &H2
Private Const MIM_APPLYTOSUBMENUS As Long = &H80000000
Private Type MENUINFO
cbSize As Long
fMask As Long
dwStyle As Long
cyMax As Long
hbrBack As Long
dwContextHelpID As Long
dwMenuData As Long
End Type
Private Declare Function DrawMenuBar 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 Declare Function GetMenu Lib "user32" _
(ByVal hWnd As Long) As Long
Private Declare Function SetMenuInfo Lib "user32" _
(ByVal hMenu As Long, _
mi As MENUINFO) As Long
Private Declare Function CreateSolidBrush Lib "gdi32" _
(ByVal crColor As Long) As Long
Private Declare Function DeleteObject Lib "gdi32" (ByVal hObject As Long) As Long
Private Sub Command1_Click()
Dim itemnum As Long
Dim hMenu As Long
Dim mi As MENUINFO
Dim i As Long
hMenu = GetMenu(Me.hWnd)
itemnum = GetMenuItemCount(hMenu)
With mi
.cbSize = Len(mi)
.fMask = MIM_BACKGROUND Or MIM_APPLYTOSUBMENUS
.hbrBack = CreateSolidBrush(vbYellow)
End With
SetMenuInfo GetMenu(Me.hWnd), mi 'main menu bar
DrawMenuBar Me.hWnd
'其实上面的程序就可以满足你的要求了，不过，加上下面的语句，显得更有意思一些
For i = 0 To itemnum - 1
With mi
.cbSize = Len(mi)
.fMask = MIM_BACKGROUND Or MIM_APPLYTOSUBMENUS
Randomize Timer
.hbrBack = CreateSolidBrush(CLng(&HFFFFFF * Rnd(i)))
End With
SetMenuInfo GetSubMenu(hMenu, i), mi
Next
End Sub
