Hi,
could someone please help me in this?
I am using a trainer template from internet that I found. The trainer does use static address like this :

Code:
private void AcheatToggle()
      {
         if (Acheat)
         {
         if (oM.OpenProcess(GameProcess) &&
                 oM.Write(0x004D955B, new byte[] { 0x74, 0x3C }))
            {
               Acheat = false;
               hListView.Items[0].BackColor = Color.FromArgb(255, 0, 0);
            }
         }
         else
         {
            if (oM.OpenProcess(GameProcess) &&
                      oM.Write(0x004D955B, new byte[] { 0xeb, 0x3C }))
            {
               Acheat = true;
               hListView.Items[0].BackColor = Color.FromArgb(0, 255, 0);
            }
         }
            }



What I need is to write via my aob's . how can I do this .

Tkank you

Scan memory for addresses whose value is the AOB of interest, then write your new, desired AOBs. This would require your to code in your program a complete process scan over the memory region where the address falls.

Alternatively, you may not need to write via AOBs if it is a pointer or static. But then why would you need to write via AOBs? In that case, use cheat engine to to find the pointer and offset(s), then use a combo of ReadProcessMemory() and WriteProcessMemory() to write the new AOBs to the address.

Yes, so you perform a scan to find addresses whose value is the AoB (using ReadProcessMemory()). If you do this correctly, your scan will return only one unique address for each updated game version. This will be the address you write to (using WriteProcessMemory()). Depending on what you want to write, you may need to borrow from darkbyte's source, to create hooks for your trainer to allocate memory and similar things. If you just need to change a few bytes, you won't need the API hook for memory allocation, just writeprocessmemory. Then you can write your new AOB to the address's value. Darkbyte made it so in his auto assembler, you put, for example, "db AF 70 B0" beneath the address to change its AOB value. using "dd" can change only one byte at a time. You can find an api hook tut for writeprocmem in C# here: http://www.pinvoke.net/default.aspx/kernel32.writeprocessmemory.

C# a bitch, so I'd advise you just learn C++, asm, and delphi if you plan to stick to this for a long time. Java is also good to know.

There is nothing wrong with using C# for this. The end result of code will look almost 100% identical to C++

For scanning for an AoB in C#:
http://www.gamedeception.net/threads/14470-FindPattern-in-C

Once you have the address you need, just use WriteProcessMemory from there to write your data. There are plenty of examples across the net on how to do this in C# (as well as any other language that can access the system API).

So since I am a newbie with this C# can someone give me a step by step instruction on how do I go with my form .

I need to add this : gamedeception.net/threads/14470-FindPattern-in-C to my project ? us module ?

then in my code , what do I need to change ?

Code:
private void AcheatToggle()
      {
         if (Acheat)
         {
         if (oM.OpenProcess(GameProcess) &&
                 oM.Write(0x004D955B, new byte[] { 0x74, 0x3C }))
            {
               Acheat = false;
               hListView.Items[0].BackColor = Color.FromArgb(255, 0, 0);
            }
         }
         else
         {
            if (oM.OpenProcess(GameProcess) &&
                      oM.Write(0x004D955B, new byte[] { 0xeb, 0x3C }))
            {
               Acheat = true;
               hListView.Items[0].BackColor = Color.FromArgb(0, 255, 0);
            }
         }
            }


right now it reads from static address and changes the bytes. also my project works with memoryeditor.dll

Hope Iam not asking to much .

My compilied exe works with the Memoryeditor.dll

If you are unsure how to use the code then you need to stop and take some time to learn the language. Spoon feeding you how to do something is going to teach you.

Can't you read?

Learn to program before!, Then you will not have the need to copy/paste.
