Hi Friends,
as the topic says,
i need your help in making a Working DLL for Vice city.

::DLL::
which write some value to a memory address

example >>>>
writing 1 byte value 245 to 0xA10B81
writing a string 'blabla' to 0x68F1F4
& writing a float value 99999.99 to 0x69C780

I want to do this by using 'Code blocks'

please tell me the code that i should write in CB for this
or a Link to your uploaded Project will be great

Actually i know what to write but the DLL is not working,
Waiting ...

If it will be loaded into gta_vc.exe, possibly ASI plugin.

C++

CODE

*(char*)0xA10B81 = 245; strcpy((char*)0x68F1F4, "blabla"); *(float*)0x68F1F4 = 99999.99;

i was using

CODE

*(float*)0x68E704 = 1.0f;   *(byte*)0x4A6B7C = 113;

but doesn't work, i am using C++ after a looong gap.
May be possible i forgot something (also using CODE BLOCK First time )
----------------------
i want the full code from TOP to END
i mean from "#include" to "return TRUE;}"
sorry for behaving like a Big NOOB here

also > found a prob. that i was building it in Debug mode
is it necessary to do that all .res & .def thing ?

Take a look at the source code of s0beit: link

[fastman92]

Yes, you forgot

CODE

void UnprotectMemory(LPVOID address, size_t size) { DWORD dwProtect; VirtualProtect(address,size,PAGE_EXECUTE_READWRITE, &dwProtect); }

Use this function before writing values if memory on certain address is protected.
Usage:

CODE

UnprotectMemory((void*)0x68E704, sizeof(float));

No need if specified memory area is not protected

Remember to do

CODE

#include "windows.h"

I am trying ....
tell you the result soon

I am not using Virtual protected Mem add BTW.

And
I did this some times ago, but didn't finished (I just started and stopped, maybe later I continue), since I just started the code is very simple (and bugged, but it writes in the address very well)

Here is it: http://pastebin.com/Anbvviei

It has a replica of the CLEO Opcode Write Memory, for string:

CODE

void WriteMemory(void* Address, int size, char* value, bool vp = false) { DWORD oldProtect; if(vp)  VirtualProtect(Address, size, PAGE_EXECUTE_READWRITE, &oldProtect); strncpy(Address, value, size); if(vp)  VirtualProtect(Address, size, oldProtect, &oldProtect); }

Is that all i have to write in dll code to make a DLL which increase the MAX hight limit to 99999.99

CODE

#include <Windows.h> BOOL WINAPI DllMain(HINSTANCE hinstDLL, DWORD fdwReason, LPVOID lpvReserved) {    switch (fdwReason)    {        case DLL_PROCESS_ATTACH:        *(float*)0x68F1F4 = 99999.99;   //mem add is not VP            // attach to process            // return FALSE to fail DLL load            break;        case DLL_PROCESS_DETACH:            // detach from process            break;        case DLL_THREAD_ATTACH:            // attach to thread            break;        case DLL_THREAD_DETACH:            // detach from thread            break;    }    return TRUE; // succesful }

after building, i get a DLL(5.50 KB) in release folder,
i put it in mss folder after renaming it to .flt
//NO EFFECT//
----------------------------
i am sure i have make some silly Mistake ...

[Ashwin the new boy]

I tried a lot but There is NO effect on those mem addresses
Can anyone make & upload a DLL Project
so that i can also start DLL coding
please ...
