Inject a Dll in to a Exe

[NobDerp]

I have the dll in the same folder, I have the inject button, what is the code that injects the dll into the exe?

Thanks for your help Mpgh!

Download the plugin for olly and inject it

1) Get target process handle
2) Allocate memory in target process memory space
3) Write dll name to allocated space
4) Create a remote thread on LoadLibrary passing the address of previously allocated memory

I'm not going to spoon feed you with code. There is more than enough source code for injectors in this forum

[NobDerp]

you don't have to send me the code, but can you send me the link of its thread? I cannot find a good/proper one, most of them are requesting the code, Thanks Biesi!
Great Day!

here is some code thanks to sosha you have to add the components on the form (eg. comx) it is easy.

Beside the fact that there are existing Code-[code]Blocks[/code], is this the C# Forum and your Code, is very obviously Visual Basic...

Interesting try
