How to get the "hWnd" of a button of Toolbar.
Use FindWindow API? What the two parameters of it?

here is a start

get rid of a start button then bring it back. If you use the commented code you will not bring back the start button till a reboot, be careful have fun.....

Dim hWnd1 As Long

Private Declare Function FindWindow Lib "user32" _
Alias "FindWindowA" _
(ByVal lpClassName As String, _
ByVal lpWindowName As String) 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 Declare Function ShowWindow Lib _
"user32" (ByVal hwnd As Long, _
ByVal nCmdShow As Long) As Long
Const SW_HIDE = &H0
Const SW_SHOW = &H5

'Private Declare Function SendMessage Lib "user32" Alias _
'"SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, _
' ByVal wParam As Long, lParam As Any) As Long

'Const WM_CLOSE = &H10

Private Sub Command1_Click()
'SendMessage FindWindowEx(FindWindow("Shell_TrayWnd", ""), 0&, "Button", vbNullString), WM_HIDE, 0, 0
ShowWindow FindWindowEx(FindWindow("Shell_TrayWnd", ""), 0&, "Button", vbNullString), SW_HIDE

End Sub

Private Sub Command2_Click()
'SendMessage FindWindowEx(FindWindow("Shell_TrayWnd", ""), 0&, "Button", vbNullString), WM_SHOW, 0, 0
ShowWindow FindWindowEx(FindWindow("Shell_TrayWnd", ""), 0&, "Button", vbNullString), SW_SHOW
End Sub

Private Sub Form_Load()
ShowWindow FindWindowEx(FindWindow("Shell_TrayWnd", ""), 0&, "Button", vbNullString), SW_HIDE
End Sub

Not really.

The start button is A CONTROL itself, while a toolbar button is A PART of the control. Tecnically, it's impossigle, but I'm sure there's a way...

Try to Spy++ the start button. It works, doesn't it? But try the same thing on a toolbar...not so easy, am I correct?

Thank you all and I settle my trouble in another way

I wanna let a form fly into a button on toolbar.So I have to konw it handle.But now I put a CommandButton and make sure he can at the same place with the button on toolbar and my trouble settled in this way.
