How to detect if window is open ?[resolved]

Well i know how to detect if an app is running by using its caption,

put this in a timer etc,

VB Code:

Dim WinWnd As Long
 WinWnd = FindWindow(vbNullString, "app caption")

but take the same app that has two different windows but both have the same caption, well you can identify sections(windows ?) within these windows by their handles.

So how would i code this to detect if a window is open by deteceting a certain part within this window by it handle...lol

You may try using EnumWindows api function (not qute sure but give it the shot. Here is a quick sample from allapi.net:

VB Code:

'Add this code to a form
Private Sub Form_Load()
    'KPD-Team 2000
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    'Set the form's graphics mode to persistent
    Me.AutoRedraw = True
    'call the Enumwindows-function
    EnumWindows AddressOf EnumWindowsProc, ByVal 0&
End Sub
'Add this code to a module
Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Boolean
Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long
Public Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As Boolean
    Dim sSave As String, Ret As Long
    Ret = GetWindowTextLength(hwnd)
    sSave = Space(Ret)
    GetWindowText hwnd, sSave, Ret + 1
    Form1.Print Str$(hwnd) + " " + sSave
    'continue enumeration
    EnumWindowsProc = True
End Function

I think you use this, which indeed finds the main window fine but doesnt seem to recognise the child window ,

VB Code:

findmain = FINDWINDOW("class in here", vbNullString)
findchild = FindWindowEx(findmain, 0&, "class in here", vbNullString)

So i have the right class of the child(from spy++) and it finds the main window fine, why wouldnt it find the child window?

What kind of window is it that you're looking for? What classname do you have?

I made a typo [resolved].
