Voici un exemple

Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVAl lpClassName As String, ByVAl lpWindowName As String) As Long

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

Private Declare Function GetClassName Lib "user32" Alias "GetClassNameA" (ByVAl hwnd As Long, ByVAl lpClassName As String, ByVAl nMaxCount As Long) As Long

Private Declare Function ShowWindow Lib "user32" (ByVAl hwnd As Long, ByVAl nCmdShow As Long) As Long

Const SW_SHOWNORMAL = 1

Const WM_CLOSE = &H10

Const gcClassnameMSWord = "OpusApp"

Const gcClassnameMSExcel = "XLMAIN"

Const gcClassnameMSIExplorer = "IEFrame"

Const gcClassnameMSVBasic = "wndclass_desked_gsk"

Const gcClassnameNotePad = "Notepad"

Const gcClassnameMyVBApp = "ThunderForm"

Private Sub Form_Load()

Dim WinWnd As Long, Ret As String, RetVal As Long, lpClassName As String

'Ask For a Window title

Ret = InputBox("Enter the exact window title:" + Chr$(13) + Chr$(10) + "Note: must be an exact match")

'Search the window

WinWnd = FindWindow(vbNullString, Ret)

If WinWnd = 0 Then MsgBox "Couldn't find the window ...": Exit Sub

'Show the window

ShowWindow WinWnd, SW_SHOWNORMAL

'Create a buffer

lpClassName = Space(256)

'retrieve the Class name

RetVal = GetClassName(WinWnd, lpClassName, 256)

'Show the classname

MsgBox "Classname: " + Left$(lpClassName, RetVal)

'Post a message To the window To close itself

PostMessage WinWnd, WM_CLOSE, 0&, 0&

End Sub

labout

Thank you man, this code working in VB.Net ??

I need log external program using FindWindow.

WinWnd = FindWindow(vbNullString, Ret)

If WinWnd = 0 Then MsgBox "Couldn't find the window ...": Exit Sub

'Show the window

ShowWindow WinWnd, SW_SHOWNORMAL

You Find and return value to : WinWnd
After use in ShowWindow

How i can similar but when external programs use Findwindow ?

So, If i understood your problem, you want to "spy" (and log) sytem-wide programs which makes calls to the FindWindow API ?

Si j'ai bien compris, vous cherchez à espionner et enregistrer, les applications, qui font appel a l'API FindWindow ?

Yes, sorry my English.

FindWindow or WriteProcessMemory

Very Thank you.

Or Some Hook to API FindWindow or WriteProcessMemory for Return incorrect values.

I Need Some code for Stop Cheats programs, most cheats use FindWindow and WriteProcessMemory API.

Thank you.

an easy way to fool such tools, is to store important values (money, energy, etc) in a different way... ex: $400 could be stored, as 123456645, using a simple Xor operation....

Is posible after my VB.Net program running, any new program using API WriteProcessMemory or FindWindow will be Closed ?

I detect new process opend using WMI : Win32_ProcessStartTrace

Thank you.

and if the cheat tools is start before ? no, be serious, you can't close every such programs, these API are not only designed to cheat in your game, you know... You can't close every tierce application you want.... think about crypt your datas, so the cheating tools won't be able to find any useable information

Really, i need Spy or Hook the API WriteProcessMemory or FindWindow filter when this API use data the GAME Process in memory.

When use Findwindow use window name the Game or WriteProcessMemory write data in PID the Game.

Idea is Spy or Log can detect that filter.

My VB.Net proyect is Encrypted, Obfuscated, etc.
but cheat working in Game program, i not have that Source.
I launch from my VB.Net code and return the PID. I can use in filter for Spy or Hook ?

Thank you.
