Send Keys to Game with DirectInput Hook
Send Keys to Game with DirectInput Hook
Hi guys.
I am trying to send keys to a online game called Shaiya.
I tried the SendMessage and PostMessage(in order to send keys while window is not focused) in c# but it's not worked for me.
It sends the key to the chat but the character is not moving.I checked the keys with spy++ and it sends them correctly.
So i did some research and i think Shaiya needs DirectInput.In order to Send Keys with DirectInput window needs focus.
I got it worked with c# but like i said it needs focus,but i want to send keys to a minimized/non focused window.To do that, i searched a lot of forums and from what i learn,i need to hook the DirectInput and change the Buffer of the keys with my keys.
I find the code below and changed the variables that needs to change and injected the dll to the game.Dll injects successfully and when i press "F5" nothing happens.I looked with spy++,it is not even sends the key to the game,i got 0 message of that key.
Here is my code. From what i see is SendKeyDInput is not working.
Anybody has a solution for this ?
and here is the log

You said.. you did right DirectInput in C# and but infocused, right?
Could you give me the resource file's?
