Window class name "afxwnd42s"

Parent Win class name is "#32770" and several buttons' class names are "afxwnd42s" (the only thing differentiating these buttons are the text). Anyone ever been in this situation? I just want to get the text of the buttons for now. Thanks

You should be able to do a FindWindow for the dialog window #32770. Then do a FindWindowEx passing
the buttons classname and caption. Then you will have the handle to the button.

I'm having trouble finding the parent window, since it's one of those funky #32770 class names. My API Spy says the parent is returning a text, but doesn't have a parent class name or handle.

Which Spy utility are you using? I only have M$ Spy++. If your getting the #32770 window, it should have a caption title?

A useful tool is the API Spy at www.patorjk.com :)

here, i think this will help you find the form name easier:

VB Code:

Option Explicit
 
'Functions, constants and types for the hook
Private Declare Function SetWindowsHookEx Lib "user32" Alias "SetWindowsHookExA" ( _
    ByVal idHook As Long, _

Sub GetWindowData(x As Long, y As Long)
 Dim hWndFrm As Long
 Dim lpClassName As String, lpString As String
 lpClassName = Space(100)
 lpString = Space(100)
 'get handle to window
 hWndFrm = WindowFromPoint(CLng(x), CLng(y))
 If hWndFrm = 0 Then Exit Sub
 'get window text (caption)
 Call GetWindowText(hWndFrm, lpString, Len(lpString))
 'get window class name
 Call GetClassName(hWndFrm, lpClassName, Len(lpClassName))
 
 With Form1
  .txthandle = Hex(hWndFrm)
  .txtCaption = lpString
  .txtClassName = lpClassName
 End With
End Sub
 
Public Sub SetMouseHook()
    If IsHooked Then
        MsgBox "Don't hook the MOUSE_LL hook twice or you'll be sorry."
    Else
        'This has to be set up as a system-wide hook
        hHook = SetWindowsHookEx(WH_MOUSE_LL, AddressOf MouseProc, App.hInstance, 0)
        IsHooked = True
    End If
End Sub
 
Public Sub RemoveMouseHook()
    Dim temp As Long
    temp = UnhookWindowsHookEx(hHook)
    IsHooked = False
End Sub
 
 
Public Function MouseProc(ByVal uCode As Long, ByVal wParam As Long, lParam As MSLLHOOKSTRUCT) As Long
    If uCode >= 0 Then
        Call GetWindowData(lParam.pt.x, lParam.pt.y)
    End If
                MouseProc = CallNextHookEx(hHook, uCode, wParam, lParam)
End Function
 
 
 
Added this to a form:
 
visual basic code:Option Explicit
 
'Always on top stuff
Private Const HWND_TOPMOST = -1
Private Const SWP_NOSIZE = &H1
Private Const SWP_NOMOVE = &H2
Private Const SWP_NOACTIVATE = &H10
Private Const SWP_SHOWWINDOW = &H40
 
Private Declare Sub SetWindowPos Lib "user32" ( _
    ByVal hwnd As Long, _
    ByVal hWndInsertAfter As Long, _
    ByVal x As Long, _
    ByVal y As Long, _
    ByVal cx As Long, _
    ByVal cy As Long, _
    ByVal wFlags As Long _
)
 
Private Sub cmdStart_Click()
'make window always on top
 SetWindowPos Me.hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOACTIVATE Or _
    SWP_SHOWWINDOW Or SWP_NOMOVE Or SWP_NOSIZE
 'set the system-wide low level mouse hook
 Call SetMouseHook
End Sub
 
Private Sub Form_QueryUnload(Cancel As Integer, UnloadMode As Integer)
 Call RemoveMouseHook
End Sub

you need three textboxes named txthandle, txtCaption, txtClassName
and a cmd button named cmdStart

Now, im having a similar problem. On the form there are 2 textboxes with teh same classname and caption, so i dont know how to send a message to one of them (it wont work just sending it)

I'm using PatorJK's API Spy. Weird thing is I can "Apply code" with it and it will click a button or whatever but the code itself is useless.

Can you post your code?

Handle = FindWindow("#32770", vbNullString)
B1 = FindWindowEx(Handle, 0&, "afxwnd42s", vbNullString)
B2 = FindWindowEx(B1, 0&, "afxwnd42s", vbNullString)
B3 = FindWindowEx(B2, 0&, "afxwnd42s", vbNullString)
afxwnds = FindWindowEx(B3, 0&, "afxwnd42s", vbNullString)
Call SendMessageLong(afxwnds, WM_LBUTTONDOWN, 0&, 0&)
Call SendMessageLong(afxwnds, WM_LBUTTONUP, 0&, 0&)

You can also try using the PostMessage API with the BM_Click message instead of the SendMessageLong.
Why not add the window caption in the parameters for the FindWindowEx? If they are buttons then they
wont have any childern windows?

Is that correct for the window class for the buttons (afxwnd42s)???
Shouldnt the buttons class be "Button"?
