[RESOLVED] Find window state of another application

Hi,

I would like to find whether another application (third party application) is in which state?

Whether it is hidden or minimized or maximized or normal, etc.

Thanks in advance.

There may be other ways, but this should work:

VB Code:

Private Type POINTAPI
    x As Long
    y As Long
End Type
 
Private Type RECT
    Left As Long
    Top As Long
    Right As Long
    Bottom As Long
End Type
 
Private Type WINDOWPLACEMENT
    Length As Long
    flags As Long
    showCmd As Long
    ptMinPosition As POINTAPI
    ptMaxPosition As POINTAPI
    rcNormalPosition As RECT
End Type
 
Private Declare Function GetWindowPlacement Lib "user32" ( _
                ByVal hWnd As Long, _
                lpwndpl As WINDOWPLACEMENT) As Long
 
Private Const SW_NORMAL As Long = 1
Private Const SW_MINIMIZE As Long = 6
Private Const SW_MAXIMIZE As Long = 3
 
Private Function GetWindowState(ByVal lhWnd As Long) As FormWindowStateConstants
    Dim winPLACE As WINDOWPLACEMENT
    winPLACE.Length = Len(winPLACE)
    GetWindowPlacement lhWnd, winPLACE
    
    Select Case winPLACE.showCmd
        Case SW_MINIMIZE
            GetWindowState = vbMinimized
        Case SW_MAXIMIZE
            GetWindowState = vbMaximized
    End Select
End Function

Ok, I am a little late for this question, I know...
But it might help all, who find this thead via a web search. :)

Yes, the most simple way would probably to use following API functions:

Code:

---

Private Declare Function IsZoomed Lib "user32.dll" (ByVal hWnd As Long) As Long
Private Declare Function IsIconic Lib "user32.dll" (ByVal hWnd As Long) As Long

---

Yet another way is by checking the Window Style bits:

Code:

---

Private Const GWL_STYLE  As Long = (-16&)      'Retrieves the window styles.
Private Const WS_MAXIMIZE As Long = &H1000000  'The window is initially maximized.
Private Const WS_MINIMIZE As Long = &H20000000  'The window is initially minimized.
Private Const WS_VISIBLE  As Long = &H10000000  'The window is initially visible.

Private Declare Function GetWindowLongW Lib "user32.dll" (ByVal hWnd As Long, ByVal nIndex As Long) As Long

Private Function IsIconic(ByVal hWnd As Long) As Boolean
    IsIconic = ((GetWindowLongW(hWnd, GWL_STYLE) And WS_MINIMIZE) = WS_MINIMIZE)
End Function

Private Function IsWindowVisible(ByVal hWnd As Long) As Boolean
    IsWindowVisible = ((GetWindowLongW(hWnd, GWL_STYLE) And WS_VISIBLE) = WS_VISIBLE)
End Function

Private Function IsZoomed(ByVal hWnd As Long) As Boolean
    IsZoomed = ((GetWindowLongW(hWnd, GWL_STYLE) And WS_MAXIMIZE) = WS_MAXIMIZE)
End Function
