C# WriteProcessMemory/ReadProcessMemory

This is my private code that i've decided to give out as i don't hack as much anymore.

To use this you add the following namespace to your application

Code:

using ReadWriteMemory;

to make a instance of it you do

Code:

ProcessMemory Mem = new ProcessMemory(/*Process Name*/);

To make the ProcessMemory active add this after your InitilizeComponent()

Code:

If(!Mem.CheckProcess())
     MessageBox.Show("Make sure your application is running or try running this as Admin");
else
    Mem.StartProcess();

Code:

using System****ntime.InteropServices;

lolz,

it's really usefull bro

thanks for posting this !

No problem i will prolly update it once in awhile with new stuff.

Add me on msn later.

so we can talk.Thank you bro

kind of ironic you say you code your own code.
I think you'l find kiwi coded that. It isnt even complete and outdated.

this.BaseAddress = 0;
this.myProcessModule = this.MyProcess[0].MainModule;
this.BaseAddress = (int)this.myProcessModule.BaseAddress;
return this.BaseAddress;

Who codes like this., looks like you used reflector to decompile an app and copy pasted.
small snippet from his old source.

Code:

        public bool StartProcess()
        {
            if (ProcessName != "")
            {
                MyProcess = Process.GetProcessesByName(ProcessName);

                if (MyProcess.Length == 0)
                {
                    //MessageBox.Show(ProcessName + " Process Not Found", "Error, Process Not Found", MessageBoxButtons.OK, MessageBoxIcon.Stop);
                    return (false);
                }

                processHandle = OpenProcess(PROCESS_ALL_ACCESS, false, MyProcess[0].Id);

                if (processHandle == 0)
                {
                    //MessageBox.Show(ProcessName + " Process Not Found", "Error, Process Not Found", MessageBoxButtons.OK, MessageBoxIcon.Stop);
                    //return (false);

                }
                return (true);
            }
            else
            {
                MessageBox.Show("Define process name first");
                return (false);
            }
        }
        public int ImageAddress()
        {
            Int32 Address;
            BaseAddress = (int)0;

            myProcessModule = MyProcess[0].MainModule;
            BaseAddress = (int)myProcessModule.BaseAddress;

            Address = (Int32)BaseAddress;
            return ((int)Address);
        } //Gets The Image Address
        public int ImageAddress(int pOffset)
        {
            Int32 Address;
            BaseAddress = (int)0;

            myProcessModule = MyProcess[0].MainModule;
            BaseAddress = (int)myProcessModule.BaseAddress;
            Address = (int)pOffset + (int)BaseAddress;

            return ((int)Address);
        }

@Pingo
i dont see

This.BaseAddress in his code... i only see it in your post... and no he havent edited it out because else we would see a message saying that it was edited x time ago by x person ...

I can still see it now. I copy pasted from his post.
public int ImageAddress()
Also half of the code is like that. The only part not in kiwi's source is the ? : operators.
Everything else is the same.

Doesnt matter anyway, i just wanted to point it out. I know kiwi wouldnt care.

But the code does work good. I used it for a good 6 months before i updated.

Um, using the 'this' keyword is a standard coding technique that most programmers use to explicitly refer to the current instance of the class. Don't see how it relates to reflector at all.

Forget what i sad about 'this', im a noob coder.
Maybe he did add it but the code was still copied from a different source.
I was only pointing out that the code wasnt done by him, yet his sig says it is.
What would you do if someone claimed one of your projects?
I'v had it done to me. Im just letting people know.

ahh doesnt matter really, atleast he shares it.

Hi guys,
I've previously been using another Read Process Memory routine (actually I got it from here in this thread)
http://www.mpgh.net/forum/250-c-prog...l-pointer.html
And it works ok.

Having said that I'd also like to try this one as it has more features.

Could anyone provide an example of how to actually use this routine now that all the code is plugged into to my compiler?
I have code to retrieve c++ multi Level pointers but c# is a bit different.
This was how I was retrieving a 2 level in C++ with no probs

int value;
int readbasepointer = 0x0763BA0; // Base of MultiLevel
int pAddress1;
int pAddress2;
int offset1 = 0x10; // 1st level
int offset2 = 0x100; // 2nd level

ReadProcessMemory(phandle,(void*)(readbasepointer) ,&pAddress1,sizeof(pAddress1),0);
ReadProcessMemory(phandle,(void*)(pAddress1 + offset1),&pAddress2,sizeof(pAddress2),0);
ReadProcessMemory(phandle,(void*)(pAddress2 + offset2),&value,sizeof(value),0);

This felt quite intuitive as I was easily able to retrieve not only the memory address but also the contents of what that memory address held.

I am sure its all straightforward and the example code provided by Kantanomo looks clear but it stops short of actually showing any examples of the actual retrieval process.
Therefore could someone give me a c# example of how to do what I was doing in c++ above in the context this routine.?
Thanks in advance.

C# WriteProcessMemory/ReadProcessMemory

This is my private code that i've decided to give out as i don't hack as much anymore.

To use this you add the following namespace to your application

Code:

using ReadWriteMemory;

to make a instance of it you do

Code:

ProcessMemory Mem = new ProcessMemory(/*Process Name*/);

To make the ProcessMemory active add this after your InitilizeComponent()

Code:

If(!Mem.CheckProcess())
     MessageBox.Show("Make sure your application is running or try running this as Admin");
else
    Mem.StartProcess();

Code:

using System.Diagnostics;
using System****ntime.InteropServices;
using System;
using System.Windows.Forms;
using System.Media;
using System.Text;
using System.Threading;

lolz,

it's really usefull bro

thanks for posting this !

No problem i will prolly update it once in awhile with new stuff.
