Say the browser was not maximized and you needed to click the stop button but didn't want to send "Esc" to the browser,  how could you find the height, x and y (of top left corner), width

is this possible?

try this:

Private Declare Function GetWindowRect Lib "user32" (ByVal hWnd As Long, lpRect As RECT) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long

Private Type RECT
        Left As Long
        Top As Long
        Right As Long
        Bottom As Long
End Type


Private Sub Command1_Click()
    Dim hWnd As Long
    Dim retval As Long
    Dim coord As RECT
    hWnd = FindWindow(CLng(0), Text1.Text)
    If hWnd = 0 Then MsgBox Text1.Text & " is not running"
    retval = GetWindowRect(hWnd, coord)
    List1.AddItem "x coordinate is " & coord.Left
    List1.AddItem "y coordinate is " & coord.Right
    List1.AddItem "Width is " & coord.Left - coord.Right
End Sub

After you get the window's handle, you can call GetWindowRect to retrieve the window's coordinates.

Dim lhWnd As Long
Dim rc as RECT

'Get the window with focus
lhWnd = GetForegroundWindow()
Call GetWindowRect(lhWnd, rc)
lTop = rc.Top
lLeft = rc.Left

No, it's the EXACT caption of the window.  e.g. "Visual Basic Question - Microsoft Internet Explorer"

Try changing the line to:

hWnd = FindWindow(vbNullString, Text1.Text)

Or, if you are looking for the handle of IE (and it is the only IE window open) use:

hWnd = FindWindow("IEFrame", vbNullString)

Just curious as to which platform your code worked in.

hWnd = FindWindow(CLng(0), Text1.Text)
