[Help][C#] Sending keystrokes to WoW

[wowhackz0r]

I am trying to send keystrokes to WoW, but for some reason i am failing. When modified, the code works correctly in other programs, but will not work with WoW. Here is the code i am using:

    static void Main()
    {
        Process[] procs = Process.GetProcessesByName("Wow");
            
       foreach (Process proc in procs)
      {        
            if (proc.MainWindowTitle == "World of Warcraft")
            {
              
               IntPtr hWnd = FindWindowEx(proc.MainWindowHandle, IntPtr.Zero, "GxWindowClassD3d", null);
                          
               
                string s = "hello";
                for (int i = 0; i < s.Length; i++)
                {
                 
                    PostMessage(hWnd, WM_KEYDOWN, VkKeyScan(s[i]), 0);

                }

               
                break;
            }
        }
                
    }

I found the window class using Spy++, did I do something wrong?

Thanks for the help

Well keys can be sent with auto it and stuff, but if you are working with wow, use BlackMagic and write to the process instead.

I forgot to mention that the goal is to NOT write memory at all.

You will find most of the help at MSDN if you are using C#, if you want to go with a passive bot why not go with auto it? I'm actually going over to begin with simple writetoprocess stuff for my own stuff as soon as i learn exceptions and more about how to use the language etc

But SendKeys Class (System.Windows.Forms)

try that

i don't like to really use others peoples work, i want more control over the bot, and i know c# (quite similar to java, which i know very well) whereas i don't know how to program in autoit, so since java isn't the best solution for a wow bot, i figured c# would work well.
thanks for the info and link

can anybody else see a problem in the code?

I know you said you don't like using other's code, but BlackMagic makes programming in C# with wow a whole lot easier. Even WhiteMagic too. Also, not completely sure where your code fails but here is how I've done it. Extra nasty code slapped in there for emphasis on whats being used. See if you can compare the differences.

public class SendKey
    {
        [DllImport("user32.dll", SetLastError = true)]
        static extern bool PostMessage(IntPtr hWnd, uint Msg, int wParam, int lParam);
        [DllImport("user32.dll", SetLastError = true)]
        static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

        private const Int32 WM_KEYDOWN = 0x0100;
        private const Int32 WM_KEYUP = 0x0101;

        public void Send(int Key)
        {
            IntPtr Handle = FindWindow(null, "World of Warcraft");
            PostMessage(Handle, WM_KEYDOWN, Key, 0);
            PostMessage(Handle, WM_KEYUP, Key, 0);
        }
    }

Even though you don't want to be using other people their code, Shynd has made a very neat PostMessage class, which I recommend for this sort of stuff.

And you don't need to copy/paste all VKey Values for the WPARAM... an build-in enum will do the work for you:

using System;
using System.ComponentModel;
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace Windows.Interop
{
    static class KeySim
    {
        #region P/Invoke
        private const uint WM_KEYDOWN = 0x100,
            WM_KEYUP = 0x101;

        [DllImport("user32", EntryPoint = "PostMessage", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        private extern static bool InternalPostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);
        #endregion

        public static void KeyDown(Keys keyDown)
        {
            if (!InternalPostMessage(ObjectManager.MemReader.MainWindowHandle,  // Insert your WowProcessHandle!
                WM_KEYDOWN,
                new IntPtr(IntPtr.Size == 4 ? (int)keyDown : (long)keyDown), // WPARAM is x64/x86 dependant, therefore cast from long/int to IntPtr
                IntPtr.Zero)) throw new Win32Exception(Marshal.GetLastWin32Error());
        }

        public static void KeyUp(Keys keyUp)
        {
            if (!InternalPostMessage(ObjectManager.MemReader.MainWindowHandle,
                WM_KEYUP,
                new IntPtr(IntPtr.Size == 4 ? (int)keyUp : (long)keyUp),
                IntPtr.Zero)) throw new Win32Exception(Marshal.GetLastWin32Error());
        }

        public static void ReleaseArrowKeys()
        {
            KeyUp(Keys.Up);
            KeyUp(Keys.Down);
            KeyUp(Keys.Left);
            KeyUp(Keys.Right);
        }
    }
}

is just how i've done it. This uses the Keys-enum in System.Windows.Forms.

What is the difference between InternalPostMessage and PostMessage? I found no documentation on the InternalPostMessage in user32

Well keys can be sent with auto it and stuff, but if you are working with wow, use BlackMagic and write to the process instead.

Also, this is _not_ the way to go.

*B*

Learner, InternalPostMessage will in the end call native dll user32 function PostMessage (same as on msdn), only its name in c# will be InternalPostMessage.

Look at definition for import:

user32.dll, entrypoint = "PostMessage"

[DllImport("user32", EntryPoint = "PostMessage", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
private extern static bool InternalPostMessage(IntPtr hWnd, uint Msg, IntPtr wParam, IntPtr lParam);


Hope it will help at least some1

Pretty simple :

PostMessage(proc.MainWindowHandle, WM_KEYDOWN, VkKeyScan(s[i]), 0);
Thread.Sleep(50);
PostMessage(proc.MainWindowHandle, WM_KEYUP, VkKeyScan(s[i]), 0);

Done, no need to complicate. Now, if you then want to convert text to key... thats harder...

That, obviously, is a best-case Aion Leveling. It

won't be so easy every time. If you don't see an improvement after you've planted the
WOW Gold, you'll have a decision to make. You can leave it

be, accepting that the player will not improve further and making decisions about his participation

accordingly. You can faze him out of Aion Gold raids, if

necessary, and only take the steps below when and if he approaches

WOW Power Leveling about why he isn't being included.

Or, you can decide to be more aggressive: to get real and
hash it Buy WOW Gold.
