 Posted: Tue Nov 06, 2012 5:43 pm Post subject: Help with my first CE asm to C++ |
 |
|
This is my first attempt at converting a CE asm script to C++. When I run the script ingame I do not crash, however when I run my version of it in C++ I do crash. Here is the CE asm script -
| Code: | [ENABLE]
alloc(IntersectRectHook,00000128)
label(returnhere_intersectrect)
label(ret_false)
IntersectRect:
jmp IntersectRectHook
returnhere_intersectrect:
IntersectRectHook:
cmp [esp],0074F806
je ret_false
mov edi,edi
push ebp
mov ebp,esp
jmp returnhere_intersectrect
ret_false:
mov eax,0
ret 0C
[DISABLE]
IntersectRect:
mov edi,edi
push ebp
mov ebp,esp
dealloc(IntersectRectHook) |
Here is my conversion to C++ (After updating the script, phiscalgm addy changed)
This is how I activate it
| Code: | void Form1::checkBox2PGM_CheckedChanged(System::Object^ sender, System::EventArgs^ e){
if(checkBox2PGM->Checked){
CreateThread(NULL, 0, (::LPTHREAD_START_ROUTINE)&PGMAinThread, NULL, 0, NULL);;
}
else
{
//asm disable
}
} |
I can't seem to find the problem, can you guys help me?[/code]

Without setuphook you're forgetting to make IntersectRect writable.
(Use VirtualProtect for that)
With setuphook you're passing it the first 4 bytes of PhysicalGMAsm instead of the address

Thank you sir, this is what I did. Works perfectly.
| Code: | /*DWORD WINAPI*/ void PGMAinThread()//(LPVOID)
{
unsigned long oldProtect;
VirtualProtect((LPVOID)ulIntersectRect, 128, PAGE_EXECUTE_READWRITE, &oldProtect);
// SetupHook(ulIntersectRect,*(DWORD*)PhysicalGMAsm,5);
//return 0;
*(BYTE*)ulIntersectRect = 0xE9;
//now that we changed the 1st byte. we want to jump over it and write 4 more bytes.
// 4 bytes is a DWORD.
*(DWORD*)(ulIntersectRect + 1) = jmp(ulIntersectRect, PhysicalGMAsm);
