Value Overflow

[Lindoz12]

Hello... I tried one of the HighJump codes in Cheat Engine 5.4: Address 008D6080, Type 4 Bytes, Value 3237909464 originally 3247909464 with highjump... But when i tried to make my trainer it got f*cked
Here is my code snippet:

Public Class Form1
Private Const PROCESS_ALL_ACCESS As Long = &H1F0FFF
Private Declare Function GetWindowThreadProcessId Lib "user32" (ByVal hwnd As Long, ByVal lpdwProcessId As Long) As Long
Private Declare Function OpenProcess Lib "kernel32" (ByVal dwDesiredAccess As Long, ByVal bInheritHandle As Long, ByVal dwProcessId As Long) As Long
Public Declare Function WriteProcessMemory Lib "kernel32" (ByVal hProcess As Long, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Integer, ByVal nSize As Long, ByVal lpNumberOfBytesWritten As Long) As Long
Public Declare Function CloseHandle Lib "kernel32" (ByVal hObject As Long) As Long
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" (ByVal Classname As String, ByVal WindowName As String) As Long
Private Declare Function ReadProcessMem Lib "kernel32" Alias "ReadProcessMemory" (ByVal hProcess As Long, ByVal lpBaseAddress As Integer, ByRef lpBuffer As Integer, ByVal nSize As Long, ByVal lpNumberOfBytesWritten As Long) As Long
Public ProcessHandle As Long
Public Sub WriteByte(ByVal Address As Long, ByVal Value As Integer)
Dim hwnd As Long, pid As Long, phandle As Long
'2: 9090, write in reverse
hwnd = FindWindow(vbNullString, "World of Warcraft")
If (hwnd <> 0) Then
GetWindowThreadProcessId(hwnd, pid)
phandle = OpenProcess(PROCESS_ALL_ACCESS, False, pid)
If (phandle <> 0) Then
WriteProcessMemory(phandle, Address, Value, 1, 0&)
End If
CloseHandle(phandle)
End If
End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WriteByte("&H8D6080", "3247909464")
TextBox1.Text = "Injection??."
WriteByte(&H8D6080, &H8
TextBox1.Text = "Injection Complete."
End Sub
End Class

But i get an error "Arithmetic operation resulted in an overflow."
How to prevent this?

WriteProcessMemory(phandle, Address, Value, 1, 0&)

WriteProcessMemory Function

Writes data to an area of memory in a specified process. The entire area to be written to must be accessible or the operation fails.

BOOL WINAPI WriteProcessMemory(
__in HANDLE hProcess,
__in LPVOID lpBaseAddress,
__in LPCVOID lpBuffer,
__in SIZE_T nSize,
__out SIZE_T* lpNumberOfBytesWritten
);
Parameters
hProcess
A handle to the process memory to be modified. The handle must have PROCESS_VM_WRITE and PROCESS_VM_OPERATION access to the process.

lpBaseAddress
A pointer to the base address in the specified process to which data is written. Before data transfer occurs, the system verifies that all data in the base address and memory of the specified size is accessible for write access, and if it is not accessible, the function fails.

lpBuffer
A pointer to the buffer that contains data to be written in the address space of the specified process.

nSize
The number of bytes to be written to the specified process.

lpNumberOfBytesWritten
A pointer to a variable that receives the number of bytes transferred into the specified process. This parameter is optional. If lpNumberOfBytesWritten is NULL, the parameter is ignored.

Return Value
If the function succeeds, the return value is nonzero.

If the function fails, the return value is 0 (zero). To get extended error information, call GetLastError. The function fails if the requested write operation crosses into an area of the process that is inaccessible.
