Office或IE4风格的ToolBar


用API 可以轻松改变 ToolBar 的风格。需要 4.70 或其以上版本的 comctl32.dll 支持。
声明：
Private Declare Function SendMessage Lib "user32" Alias _
"SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
ByVal wParam As Integer, ByVal lParam As Any) As Long
Private Declare Function FindWindowEx Lib "user32" Alias _
"FindWindowExA" (ByVal hWnd1 As Long, ByVal hWnd2 _
As Long, ByVal lpsz1 As String, ByVal lpsz2 As _
String) As Long
Private Const WM_USER="&H400"
Private Const TB_SETSTYLE="WM_USER" + 56
Private Const TB_GETSTYLE="WM_USER" + 57
Private Const TBSTYLE_FLAT="&H800"
Private Const TBSTYLE_LIST="&H1000"
函数：
' tlbToolbarStyle :
'1 为 Office97 风格
'2 为 IE4 风格
Public Sub ToolbarStyle(tlb As Toolbar, _
tlbToolbarStyle As Long)
Dim lngStyle As Long
Dim lngResult As Long
Dim lngHWND As Long ' Find child window and get style bits
lngHWND="FindWindowEx(tlb.hwnd," 0&, _
"ToolbarWindow32", vbNullString)
lngStyle="SendMessage(lngHWND," _
TB_GETSTYLE, 0&, 0&) ' Use a case statement to get the effect

Select Case tlbToolbarStyle
Case 1: ' Creates an Office 97 like toolbar
lngStyle="lngStyle" Or TBSTYLE_FLAT
Case 2: ' Creates an Explorer 4.0 like toolbar,
' with text to the right
' of the picture. You must provide text
' in order to get the effect.
lngStyle="lngStyle" Or TBSTYLE_FLAT _ Or TBSTYLE_LIST
Case Else
lngStyle="lngStyle" Or TBSTYLE_FLATEnd Select
' Use the API call to change the toolbar

lngResult=SendMessage(lngHWND, _
TB_SETSTYLE, 0, lngStyle) ' Show the effects
tlb.Refresh

End Sub

在 Form 装入时调用:
Private Sub Form_Load()
Call ToolbarStyle(Me.Toolbar1, 2) ' …
End Sub

关于ToolBar 风格的说明：
Office 风格的 Toolbar 是指在鼠标移动到 ICON 后， 会出现边框。如我们在 VB5 中
用的一样。 而comctl的ToolBar是没有该效果的。 IE4 风格的 Toolbar 可以在ICON下
面出现文字， 如同 IE4 中的Toolbar 一样。(可能是反一下。。。。)
