Making injector

Hello!
i'm making a simple injector but i have a error : this doesnt inject
This is the code

The Source code used is of a very Simple kind. Nowadays Games are very Advanced and they have good Hacking Prevention Systems.
You need more Codes brotha.

[dragonattak]

can you make a example please?

Google: "code cave injection"

Google: "code cave injection"

like u said

Nice source I think I see Auto Close.... Now you need to put a browse button for the .DLL so add a button and a OpenFileDialog and put this code:

OpenFileDialog1.Filter = "DLL (*.dll) |*.dll"
OpenFileDialog1.ShowDialog()
Dim FileName As String
FileName = OpenFileDialog1.FileName.Substring(OpenFileDialog1 .FileName.LastIndexOf("\"))
Dim DllFileName As String = FileName.Replace("\", "")
Me.TextBox2.Text = (DllFileName)

then you can add like a Process List but... well if you need something more tell me... Oh YES and you need a Timer Sorry If its alredy there I dont have time to see them

Moved in the coding section

[dragonattak]

just close i just used another code ^^

[Decobez]

@dragonattak

hey man i have the same code, hit me up a PM and ill give u a tut

[SteamAss]

@dragonattak PM/VM me if you need full code and tut =D I can help you

Why dont you stop making injectors? There is alot of them, You dont need another copy/paste injector.

[Lakshay]

You gotta add Bypass if u need to Inject hacks to a good game.

[dragonattak]

lol i made already hack with another code ^^
