Need Help coding MW2_Admin/Hosting Aid

Posts 1–11 of 11 · Page 1 of 1

Hi all

i am not good programer & and i'm totally new to this accessing other programs memory

I am making Admin tool using VB 2008 for MW2 1.0.182 (AlterIW 1.3.37 version)
with options like

+Change Map
+Maplist
+Change Game Mode
+Restart Map & Fast restart
+Kick Players
+Ban Player
+Force host
+InGame Console Commands
+Changing Scorelimit & TimeLimt
+Profile Backup & Restore
+Sending Welcome & Warning to all Players
+Nickname Editor with coloured name
+Costume Server List
+Show FPS & Changing default 4 ping bars to 10 bar
+Custume Commands

i can send data from my app to the console & etc by Sending text commands to console window textbox
i Know we can show messages in game by editing 00A21028 of iw4mp.exe (Displays string as Chat message)

the problem i am facing is getting players list for Kick And TempBan function

1)i know Clientinfo is at 0x8EB248 (but have no idea how to get that info to my app as a string & also the client No.)
(Memory address as per This Post)

2)how to detect if the user is a host or not & if yes then he is in game or has returned to the lobby

3) Sending String to 00A21028 memory location

Plz Guys i would be greatful if any one can can give tutorial or code for it.

Thanks

Ok Guys i was able to read Write integer date but wasnt able to read String

What i'm trying to is reading ClientInfo from Modern Warfare 2
As per This post it is a structure

Can Any one help ????

hire is the code i try but didn't work.

Code:

And also what the diffrence between these Addressing type 0x8EB248, iw4mp.exe+621028, 00437C4C
and how do i use this in Vb 2008

I can't help, but I can tell you not to double post.

How about creating some modules instead of making a big pile of code?
I'll see what i can do

Code:

struct CEntity
{
    char Unknown000[220]; //0x0
    int ClientNumber; //0xDC
    int iEntityType; //0xE0
    char Unknown001[288]; //0xE4
};

I don't know what that looks like in Vb, but i'll give it a try anyway(fix it if needed ^^):

Code:

Public Structure CEntity
    <VBFixedString(220)> Public Unknown000 As String
    Public ClientNumber as Integer
    Public EntityType as Integer
    <VBFixedString(288)> Public Unknown001 As String
End Structure

Dim playerList(18) as CEntity 'Turn me into an array with CEntity as type, with 18 cells

Then update the struct in a timer(only if we are in a game):

Code:

Dim AreWeInGame as Integer
ReadMemory(&H7F4848, AreWeInGame, 4) ' an integer is 4 bytes long
if(AreWeInGame = 1) then
    ReadMemory(&H8F7A78, playerList, 9288) '9288 = 0x204*18
End if

Code:

Public Bool IsEntityValid(Dim pEnt as CEntity)
    Dim LocalClientNumber as Integer
    ReadMemory(&H7F493C, LocalClientNumber, 4) 'An integer is 4 bytes
    if(pEnt.EntityType = 1 and not pEnt.ClientNumber = LocalClientNumber) then 'If it is a human and doesn't have the same clientnumber as we do.
        return True 'it is valid
    Else 'else
        return False 'it is not valid
    End if
End

Then you'd need to send commands to the console, which I don't think is possible(because you need to inline it unless someone finds a function that can be called with CreateRemoteThread if VB even has that)

Good luck o_O

My first action as minion....yay

First of all
Thank you all for repling, Especially Hell_Demon

I did as you told me, but its giving a error

What i did was

1) Replaced CClientInfo structure with 1st code box codes given by Hell_Demon both in Module Memory & Class Form1

2) Added a Timer & Add the code in ur 3rd code box to Timer1_Tick function
what time interval should i give this timer ??

3) Added the codes in last code box, but gave error so i edited the the first & last line of the function to this

Code:

Public Function IsEntityValid(ByVal pEnt As CEntity) As Boolean
    End Function

Now there was 1 error left
The error was in the statement in Timer_tick function
ReadMemory(&H8F7A78, playerList, 9288)
Error was No ReadMemory overload code be call because "playerList" is a Structure.
So, i Added this Function in the #Region "Memory reading/Writing"
& changed the Value & mValue from String to CEntity

Code:

Public Sub ReadMemory(ByVal Address As Long, ByRef Value As CEntity, ByVal Size As Integer)
        Try
            Dim mValue As CEntity

            Dim GameReadWrite As Integer
            Dim PID As Integer = Game_Hwnd()
            GameReadWrite = OpenProcess(PROCESS_READ_WRITE_QUERY, False, PID)

            ReadProcessMemory(GameReadWrite, Address, mValue, Size, 0)
            Value = mValue

            CloseHandle(GameReadWrite)
        Catch Ex As Exception
            MsgBox(Ex.ToString)
        End Try
    End Sub

Now ReadProcessMemory function gave same error So i Add & Just Changed Sting to CEntity

Code:

    Public Declare Function ReadProcessMemory Lib "kernel32" (ByVal hProcess As IntPtr, ByVal lpBaseAddress As Long, ByRef lpBuffer As CEntity, ByVal nSize As Int32, ByVal lpNumberOfBytesWritten As Int32) As Long

Now the same ReadMemory Statement in timer_Tick function
Error is

Code:

Error	3	Overload resolution failed because no accessible 'ReadMemory' can be called with these arguments:
    'Public Sub ReadMemory(Address As Integer, ByRef Value As String, Length As Integer)': Value of type '1-dimensional array of WindowsApplication1.Form1.CEntity' cannot be converted to 'String'.
    'Public Sub ReadMemory(Address As Long, ByRef Value As Memory.CEntity, Size As Integer)': Value of type '1-dimensional array of WindowsApplication1.Form1.CEntity' cannot be converted to 'WindowsApplication1.Memory.CEntity'.
    'Public Sub ReadMemory(Address As Long, ByRef Value As Integer, Size As Integer)': Value of type '1-dimensional array of WindowsApplication1.Form1.CEntity' cannot be converted to 'Integer'

Thanks

See if casting works((Int)&playerList)

Error is gone but when i try using it gives this error

"Type of argument 'Number' is 'WindowsApplication1.Form1+CEntity[]', which is not numeric."

Was able to read from &HA21028 this address (its string data allocated for Chat string) by changing

ReadProcessMemory(GameReadWrite, Address, mValue, Size, 0)
to
ReadProcessMemory(GameReadWrite, Address, mValue, Size, 0&)

But not from &H8F7A78

heres the code i'm using to read 1 byte at a time

Code:

Const PAGE_EXECUTE_READWRITE As Long = &H40
        Dim tr As Integer
        Static tr1 As Integer = 0
        Dim GameReadWrite As Long
        Dim Addres1 As Long = (&H8F7A78 + tr1)
        Dim PID As Integer = Game_Hwnd()
        GameReadWrite = OpenProcess((PROCESS_ALL_ACCESS), False, PID)
        Dim Oldprotect1, Oldprotect2 As Integer
        Do
            Try
                TextBox2.Text = VirtualProtectEx(GameReadWrite, Addres1, 1, PAGE_EXECUTE_READWRITE, Oldprotect1)
                TextBox3.Text = ReadProcessMemory(GameReadWrite, Addres1, tr, 1, 0&)
                TextBox4.Text = VirtualProtectEx(GameReadWrite, Addres1, 1, Oldprotect1, Oldprotect2)

            Catch Ex As Exception
                MsgBox(Ex.ToString)
            End Try
            If tr <> 0 Then
                TextBox1.Text = Chr(tr).ToString
            End If
            Label1.Text = tr1.ToString
            tr1 = tr1 + 1
        Loop While TextBox1.Text = ""
        CloseHandle(GameReadWrite)

Sorry for double posting i cant edit my above post

heres the whole code

Button6 is what i'm working, i am able to read 1 byte at time and convert it to Char using Chr() function but it returns unreadable chars like @#^ etc.
And i'm not able to read the whole struct

i start iw4mp
then i start a private match
then i test my application
