    BM_CLICK not working

    I am opening a web page (HTML Document type) that also opens a pop up that has "OK" button. I have the code to click the "OK" button but it is not working. code does find popup window and "OK" Button


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

    Private Const BM_CLICK As Long = &HF5&

    Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long


    Sub EMS_P1()
    '------P1--------
    Set objIE = CreateObject("InternetExplorer.Application")
    objIE.Top = 0
    objIE.Left = 0
    objIE.Width = 800
    objIE.Height = 600
    objIE.AddressBar = 0
    objIE.StatusBar = 0
    objIE.Toolbar = 0
    objIE.Visible = True 'We will see the window navigation

    objIE.navigate ("http://claimportalch.prodlb.travp.net/claimportalcommon2/default.aspx")

    'Do
    'DoEvents
    'Loop Until objIE.ReadyState = 4

    Dim hwndParent As Long
    hwndParent = FindWindow(vbNullString, "Message from webpage")
    Debug.Print ("findwindow: " & hwndParent)

    Dim hwndButton As Long
    hwndButton = FindWindowEx(hwndParent, ByVal 0&, "Button", "OK")
    Debug.Print ("OK: " & hwndButton)

    hwndButton = PostMessage(hwndButton, BM_CLICK, 0, 0)
    Debug.Print ("Clicked: " & hwndButton)
    End sub


    Pop up (doesn't look HTML) has title "Message from webpage". it has just one button name "OK". Can someone help with VBA code to either click it or press enter key so that pop disappears. I have used Send and postmessage functions but they are not able to click the "OK" button
    Here is what I get when using PostMassage

    findwindow: 3806110
    OK: 2688002
    Clicked: 1

    Re: BM_CLICK not working

    i tried to test, but the navigation failed
    i do my best to test code works before i post it, but sometimes am unable to do so for some reason, and usually say so if this is the case.
    Note code snippets posted are just that and do not include error handling that is required in real world applications, but avoid On Error Resume Next

    dim all variables as required as often i have done so elsewhere in my code but only posted the relevant part

    come back and mark your original post as resolved if your problem is fixed

    Re: BM_CLICK not working

    Have you tried alternative messages? Sendmsg WM_LBUTTONDOWN then WM_LBUTTONUP
    I've had similar situations where that has worked and other click messages didn't, and others where PostMessage didn't work but SendMessage did; I always use the latter with the WM_ messages above.

    Replace
    hwndButton = PostMessage(hwndButton, BM_CLICK, 0, 0)
    with
    Call SendMessage(hwndButton, WM_LBUTTONDOWN, 0&, ByVal 0&)
    Call SendMessage(hwndButton, WM_LBUTTONUP, 0&, ByVal 0&)


    If no-go also try replacing the 'Call SendMessage' with 'Call PostMessage' (no other changes needed). Btw, neither of those returns an HWND, so never use hwndButton = with them.

    If you need the declares:
    Public Const WM_LBUTTONDOWN = &H201
    Public Const WM_LBUTTONUP = &H202
