'Com esta dica você poderá dar um incremento visual em seus programas, incluindo bitmaps nos ítens de menu.
'Coloque o código a seguir em um módulo:
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 As Long = &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 As Long = &H2
Public Const MIIM_TYPE As Long = &H10
Public Const MFT_STRING As Long = &H0&
'Agora crie um formulário, coloque nele os menus, um picturebox (autosize=true) com um bitmap de tamanho máximo 13x13 e adicione o seguinte código em um botão:
Private Sub Command1_Click()
Dim hMenu As Long, hsubMenu As Long, hID As Long
'Recupera o handle do menu formulário
hMenu = GetMenu(Form1.hWnd)
'Recupera o handle do 1º menu
hsubMenu = GetSubMenu(hMenu, 0)
'Pega o menuId do 1º submenu
hID = GetMenuItemID(hsubMenu, 0)
'Adiciona o bitmap ao submenu
SetMenuItemBitmaps hMenu, hID, MF_BITMAP, _
Picture1.Picture, Picture1.Picture
'Você pode colocar dois bitmaps no menu
'Uma para o estado selecionado, e outro
'para o não selecionado.
End Sub
