[Help] Get the Max HP ..

I'm trying to get the max hp based on the address ..
I got this in olly:

Code:

009D4B60   . 8B4424 04      MOV EAX,DWORD PTR SS:[ESP+4]
009D4B64   . 8981 58040000  MOV DWORD PTR DS:[ECX+458],EAX
009D4B6A   . A1 0CF81001    MOV EAX,DWORD PTR DS:[110F80C]
009D4B6F   . 85C0           TEST EAX,EAX
009D4B71   . 74 17          JE SHORT sro_clie.009D4B8A
009D4B73   . 8B88 FC060000  MOV ECX,DWORD PTR DS:[EAX+6FC]
009D4B79   . 85C9           TEST ECX,ECX
009D4B7B   . 74 0D          JE SHORT sro_clie.009D4B8A
009D4B7D   . C74424 04 0000>MOV DWORD PTR SS:[ESP+4],0
009D4B85   .^E9 2682E5FF    JMP sro_clie.0082CDB0
009D4B8A   > C2 0400        RETN 4

Now I tried codecave:

PHP Code:


			
DWORD Address = 0;
DWORD dwEAX = 0;

__declspec(naked)  void HPCodeCave(void)
{
    printf("Getting the HP value .. \n");

    __asm
    {
        pop Address
        mov dwEAX, EAX
        pushad
    }

    if(dwEAX >= 0)
        printf("HP: %d", dwEAX);
    else
        printf("Waiting..\n");

    __asm
    {
        popad
        MOV DWORD PTR DS:[ECX+0x458],EAX
        push Address
        ret
    }
}

PHP Code:


			
Codecave(0x009D4B64, HPCodeCave, 1);

PHP Code:


			
VOID WriteBytesASM(DWORD destAddress, LPVOID patch, DWORD numBytes)
{
    // Store old protection of the memory page
    DWORD oldProtect = 0;

    // Store the source address
    DWORD srcAddress = PtrToUlong(patch);

    // Make sure page is writeable
    VirtualProtect((void*)(destAddress), numBytes, PAGE_EXECUTE_READWRITE, &oldProtect);

    // Do the patch (oldschool style to avoid memcpy)
    __asm
    {
        nop                        // Filler
        nop                        // Filler
        nop                        // Filler

        mov esi, srcAddress        // Save the address
        mov edi, destAddress    // Save the destination address
        mov ecx, numBytes        // Save the size of the patch
Start:
        cmp ecx, 0                // Are we done yet?
        jz Exit                    // If so, go to end of function

        mov al, [esi]            // Move the byte at the patch into AL
        mov [edi], al            // Move AL into the destination byte
        dec ecx                    // 1 less byte to patch
        inc esi                    // Next source byte
        inc edi                    // Next destination byte
        jmp Start                // Repeat the process
Exit:
        nop                        // Filler
        nop                        // Filler
        nop                        // Filler
    }

    // Restore old page protection
    VirtualProtect((void*)(destAddress), numBytes, oldProtect, &oldProtect);
}

VOID Codecave(DWORD destAddress, VOID (*func)(VOID), BYTE nopCount)
{
    // Calculate the code cave for chat interception
    DWORD offset = (PtrToUlong(func) - destAddress) - 5;

    // Buffer of NOPs, static since we limit to 'UCHAR_MAX' NOPs
    BYTE nopPatch[0xFF] = {0};

    // Construct the patch to the function call
    BYTE patch[5] = {0xE8, 0x00, 0x00, 0x00, 0x00};
    memcpy(patch + 1, &offset, sizeof(DWORD));
    WriteBytesASM(destAddress, patch, 5);

    // We are done if we do not have NOPs
    if(nopCount == 0)
        return;

    // Fill it with nops
    memset(nopPatch, 0x90, nopCount);

    // Make the patch now
    WriteBytesASM(destAddress + 5, nopPatch, nopCount);
}

Console output:

Code:
