Minimising Game

Hey,

Im trying to minimise a game but i'm having problems. The game doesn't appear to minimse. However the Windows Calculator does. I'll show you some of my code, which is messy and rubbish, so if you could share some source or point me into the right direction on how to minimise a game that would be great. Alot of the code is not needed but i'm that much of a noob :cool:

Code:

---

Option Explicit
Private Declare Function GetActiveWindow Lib "user32" () As Long
Private Declare Function 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) As Long
Private Const HWND_TOPMOST = -1 'bring to top and stay there
Private Const SWP_NOMOVE = &H2 'don't move window
Private Const SWP_NOSIZE = &H1 'don't size window
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Const HWND_NOTOPMOST = -2
Private Type POINTAPI
    x As Long
    Y As Long

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

Private Declare Function GetWindowPlacement Lib "user32" (ByVal hWnd As Long, lpwndpl As WINDOWPLACEMENT) As Long
Private Declare Function SetWindowPlacement Lib "user32" (ByVal hWnd As Long, lpwndpl As WINDOWPLACEMENT) As Long
Private Const SW_SHOWMINIMIZED = 2
Private Const SW_SHOWMAXIMIZED = 3
Private Const SW_SHOWNORMAL = 1
Private sAppName As String, sAppPath As String



Private Sub Command1_Click()
Shell sAppPath, vbMinimizedFocus
End Sub

Private Sub Command2_Click()
'Call EndTask(sAppName)
End Sub

Private Sub Command3_Click()
Dim app_hwnd As Long
Dim ofp As WINDOWPLACEMENT
app_hwnd = FindWindow(vbNullString, sAppName)
ofp.length = Len(ofp)
ofp.showCmd = SW_SHOWMINIMIZED
SetWindowPlacement app_hwnd, ofp
End Sub

Private Sub Command4_Click()
Dim app_hwnd As Long
Dim ofp As WINDOWPLACEMENT
app_hwnd = FindWindow(vbNullString, sAppName)
ofp.length = Len(ofp)
ofp.showCmd = SW_SHOWMAXIMIZED
SetWindowPlacement app_hwnd, ofp
End Sub

Private Sub Form_Load()
sAppName = "Operation Flashpoint"
sAppPath = "C:\Program Files\Codemasters\OperationFlashpoint\FLASHPOINTRESISTANCE.EXE"
Call SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE)
End Sub

Private Sub Mini_Click()
Dim app_hwnd As Long
Dim ofp As WINDOWPLACEMENT
app_hwnd = FindWindow(vbNullString, sAppName)
ofp.length = Len(ofp)
ofp.showCmd = SW_SHOWMINIMIZED
SetWindowPlacement app_hwnd, ofp
End Sub

Private Sub Timer1_Timer()
If GetActiveWindow = 0 Then
        Call SetWindowPos(hWnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE)
    End If
End Sub

Thanks in advance :)

I'm probably way off base, but is there some reason why you can't just say Me.WindowState = vbMinimized?

Yeah can't do that because the application i want to minimise isn't "me" it's a completely different programme. It's a retail PC game. Lol you should understand now.

VB Code:

Option Explicit
 
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal lpClassName As String, ByVal lpWindowName As String) As Long
Private Declare Function ShowWindow Lib "user32" (ByVal hwnd As Long, ByVal nCmdShow As Long) As Long
Private Const SW_MINIMIZE = 6
 
Private Sub Command1_Click()
Dim lngMinimizeIt As Long
lngMinimizeIt = FindWindow(vbNullString, "Put Window Caption Here")
ShowWindow lngMinimizeIt, SW_MINIMIZE
End Sub

A lot of games cannot be minimized. I think DirectX is one type that doesn't allow it.
