WM_LBUTTONDOWN在W7上用不了

Button ＝１表示左键，２表示右键 ，不需要用到WM_LBUTTONDOWN

类代码
Public Const DefaultIconIndex = 1 '图标缺省索引
Public Const WM_LBUTTONDOWN = &H201 '按鼠标左键
Public Const WM_RBUTTONDOWN = &H204 '按鼠标右键
Public Const NIM_ADD = 0 '添加图标
Public Const NIM_MODIFY = 1 '修改图标
Public Const NIM_DELETE = 2 '删除图标
Public Const NIF_MESSAGE = 1 'message 有效
Public Const NIF_ICON = 2 '图标操作（添加、修改、删除）有效
Public Const NIF_TIP = 4 'ToolTip(提示）有效

'API函数声明

End Type



'函数定义
'添加图标至通知栏
Public Function Icon_Add(iHwnd As Long, sTips As String, hIcon As Long, IconID As Long) As Long
'参数说明：iHwnd：窗口句柄，sTips：当鼠标移到通知栏图标上时显示的提示内容
'hIcon：图标句柄，IconID：图标Id号
Dim IconVa As NOTIFYICONDATA

.hwnd = iHwnd
.szTip = sTips + Chr$(0)
.hIcon = hIcon
.uID = IconID
.uCallbackMessage = WM_LBUTTONDOWN
.cbSize = Len(IconVa)
.uFlags = NIF_MESSAGE Or NIF_ICON Or NIF_TIP
Icon_Add = Shell_NotifyIcon(NIM_ADD, IconVa)
End With
End Function

'删除通知栏图标(参数说明同Icon_Add)
Function Icon_Del(iHwnd As Long, lIndex As Long) As Long
Dim IconVa As NOTIFYICONDATA
Dim L As Long
With IconVa
.hwnd = iHwnd
.uID = lIndex
.cbSize = Len(IconVa)
End With
Icon_Del = Shell_NotifyIcon(NIM_DELETE, IconVa)
End Function

'修改通知栏图标(参数说明同Icon_Add)
Public Function Icon_Modify(iHwnd As Long, sTips As String, hIcon As Long, IconID As Long) As Long

.cbSize = Len(IconVa)
.uFlags = NIF_MESSAGE Or NIF_ICON Or NIF_TIP
Icon_Modify = Shell_NotifyIcon(NIM_MODIFY, IconVa)
End With
End Function

窗口代码
Private Sub Form_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
Dim L
L = X \ 15
'点击通知栏图标，用鼠标右键时调出弹出菜单
If L = WM_RBUTTONDOWN Then
Me.PopupMenu main
'点击通知栏图标，用鼠标左键时，将通知栏图标改为另外的图标
ElseIf L = WM_LBUTTONDOWN Then
Call Icon_Del(Me.hwnd, 0) '删除通知栏图标
Me.WindowState = 0
Me.Show '调出窗口
End If

End Sub

Private Sub Form_Resize()
If Me.WindowState = 1 Then
'MinFlag = True
Me.Visible = False '隐藏窗口
'将窗口图标加入通知栏
Call Icon_Add(Me.hwnd, Me.Caption, Me.Icon, 0)
End If

End Sub


Private Sub Exit_Click(Index As Integer)
Call Icon_Del(Me.hwnd, 0) '删除通知栏图标
End '退出程序

End Sub

Private Sub Show_Click(Index As Integer)
Call Icon_Del(Me.hwnd, 0) '删除通知栏图标
Me.WindowState = 0
Me.Show '调出窗口

End Sub

我试过用BUTTON代替，但是光标一到那个图标的位置就已经反应了，我还没按，不知道为什么，因为这些代码都是从网上找的，麻烦版大帮忙看看，主要是实现窗口图标在托盘显示而且图标没有走样，谢谢。

.uCallbackMessage = WM_LBUTTONDOWN表示托盘消息都用WM_LBUTTONDOWN发送，应该用自定义消息

版大我没看懂你在说什么啊，是不是把.uCallbackMessage = WM_LBUTTONDOWN里的WM_LBUTTONDOWN改成我自己定义的东西就行了？

MSDN的说明
uCallbackMessage
Application-defined message identifier. The system uses this identifier for notification messages that it sends to the window identified in hWnd. These notifications are sent when a mouse event occurs in the bounding rectangle of the icon.
意思是只要对托盘图标有任何动作都会向窗口发送uCallbackMessage消息，这个消息由用户指定，VC里只要在WindowProc函数中case这个消息
你设置uCallbackMessage = WM_LBUTTONDOWN跟系统的左键消息冲突，所以图标一动就会触发Form_MouseDown
VB里处理自定义消息需要自己实现WindowProc　http://www.b181/bianchen/bianchen-105536.html

只是部分的W7系统不行，这个不知道是为什么，其它都好正常的，响应到左右键的按下动作，而部份的就是不行，咋按也没反应，这又是为什么？我测试过，正常的机子 L = X \ 15 是等于513，而就刚好与WM_LBUTTONDOWN的值一样，所以能就触发那个过程，而不正常的机子就是409，可是我修改那值后就会不管我按不按键它都会反应。不知道版大有没有看懂我在写什么了

跟鼠标相关消息没搜索到409的，因为你的代码不是规范写法，所以正常应该是都不能用的，能用也是巧合，跟系统有关

原来是这样，版大能不能推荐一下关于这方面知识的书本，我这方面基本不懂，现在我用另一个控件顶上了，感谢版大。
