[c# example] memory reading

[kantaki]

Hello,

i want to apologize for my previous questions here.
i read many guides about memory reading in c#, especially for WoW.

but i hate it to ask many questions and i dont wanna disturb you too much, so

do u have an old source code in c# 4.0 that reads some information though memory reading from a program of your choice ? (without external dlls. for example , blackmagic )

for example :
i dont know...
the url of an active internetexplorerwindow

somthing like this.

this would help me to get an overview of how it is done and with the well documented .net lib, it will be very easy for me to understand your code.

ps:
i read 1 book in c++ (primer)
head first java
heads first c#

im still very unexperienced, but i hope you can help me with that.

thanks

What you could do is attempt to use Cheat Engine on iexplorer.exe to find the text in the URL Textbox. Then, in order to read this dynamically, call ReadProcessMemory on the address (after opening up the process ofc) and read one character at a time until you reach a null character. Append all these characters together and then you will have a string.

thank you, i will try it.

i followed a tutorial for runes of magic and i tried to convert their code for my usage, but i dont know.. something went wrong
i just dont know what rw means and why the byte array has a length of 24.

btw i know that i have to use the base + offset, but did i make it right ?

i hope someone can tell me what i made wrong

thank you <3
edit:
i read your post @sychotix
but they used this method for getting a string. im confused

 private void button1_Click(object sender, EventArgs e) {

            Process[] iexp = Process.GetProcessesByName("iexplore");
            if (iexp.Length == 0) {
                listBox1.Items.Add("NOT FOUND");
            }
            Process internet = iexp[0];
            uint baseAddress = (uint)internet.MainModule.BaseAddress.ToInt32();
            IntPtr readHandle = OpenProcess(0x0010, false, (uint)internet.Id);
            byte[] bytes = new byte[24];
            uint rw = 0;
            uint size=sizeof(int);

            ReadProcessMemory(readHandle, ((IntPtr)baseAddress + 0x0D6B058E), bytes, (UIntPtr)24, ref rw);
            string ownedcore = Encoding.UTF8.GetString(bytes);
            ReadProcessMemory(readHandle, (IntPtr)baseAddress + 0x00528744, bytes, (UIntPtr)size, ref rw);
            int someNumber = BitConverter.ToInt32(bytes, 0);

            listBox1.Items.Add(ownedcore);
            listBox1.Items.Add(someNumber);
            
        }
    }

You cant just copy and past it and ask why it does not work... You could try and look this stuff up... its not hard...

ReadProcessMemory function
You will find all information on ReadProcessMemory....

Adding the base address is not always used for every programs..

All the code does is read the values as bytes and then converts it into a string. No idea about the 24.. it could be as long as you want really..
Example : Reads 0x41 and then converts it into the letter A... I think...

I have no idea if your offsets are correct... but other than that... looks good... I dont know C# that well. I would use C++ but thats up 2 you

yes after spending i dont know 50 hours, im nearly finished with the basics =D. yes i was realy slow.
atm my problem is that my baseaddress from c# is wrong

I dont use C#, so I dont really know how to get that base-address, but take a look at BlackRain,
ObjectManager.cs - blackrainobjects - A simple but effective Object Manager for World of Warcraft in C# - Google Project Hosting

        private static uint WowBaseAddress
        {
            get 
            {
                return WowProcess.MainModule == null ? 0 : (uint)WowProcess.MainModule.BaseAddress;
            }
        }

do they only use integers or can they use floats aswell?
