Hi everyone

Recently, I've been trying to code a working DLL Injector in C++. I tried to code the whole thing by myself but failed. So I thought about finding a working DLL Injection Code on google to help me.

This is what I found :

You really should try to do some more checks if an error has occured, and if an error occured, then print where the error occured, together with the return value of GetLastError()

The value returned by GetLastError() can be found here, for further explination: http://msdn.microsoft.com/en-us/library/ms681381.aspx

If you try your source code at XP, it might succeed, but as you mentioned, you are running Vista, causeing this line to fail:

Ok Guys, I've been working on this almost the whole day, trying to set the Token Privilege and everything. Until I found again that it WAS NOT the problem. I've did several Debugging test and found what I said before : PROCESS_ALL_ACCESS works, the problem is in my CreateRemoteThread function wich always return a NULL value.

I tried multiple DLL Injection code, and found that everytime, the problem was with the CreateRemoteThread function.

I even tried a software that injects your DLL in a process of your choice. Guess what? The software log said : "Error in CreateRemoteThread". Looks like the problem is on my PC, right?


I'm so confused now, what should I do?

Here is a perfectly working dll injector. It's coded in C++ 6.0.

attachment too big and "I'm not worthy enough to post an url." Wtf.

Here it is anyways www dot mediafire dot com/?1njci5mnnmm

I have used it with a dll cheat I made for counter-strike and it never had any problems.

The source code you posted works just fine for me, and im running Vista Business...

This is the source for the .dll i inject:

Anden, I tested the DLL that I made with an Injection Software and my DLL worked. So the problem is obviously in my c++ injector.

Oh and himpula, I tried your Injector, but what ever I do, the injector never find the DLL...

I changer the process to notepad.exe :

Unless it has changed in Vista.. shouldn't the path to your desktop folder be "?:\Documents and Settings\[user]\Desktop"? Try using SHGetFolderPath / GetOpenFileName.

Omg, I just found something. Since the beginning, I was always testing my injection codes on Notepad or the Calculator. SoI tried on msnmsgr.exe (MSN Messenger) and the injection worked! But still, I have a major problem, 1 time out of 4, the injection works. The other times, they say that the injection was succesful but my message box never appear (my dll is supposed to show a MessageBox). And yes my DLL works properly, tested it with an Injection Software...

What is causing that?

Sloppy --> "?:\Documents and Settings\[user]\Desktop" makes no difference.

Thanks for helping me guys, I can feel that I'm damn close to get it to work.


EDIT : I finaly got it. It was a weird thing. Most of the time, the injector did NOT allocate enought space for the DLL... fixed everything and now it works like a charm. There is only one more thing I need to know... Normaly, for the DLL, I just put : "C:\\Users\\Maskote\\... ". But today I sent the injector to one of my friend so he can test if I really fixed the problem. To do this, I changed the path "C:\\Users\\Maskote\\Desktop\\Hacking.dll" to "Hacking.dll" and joigned the DLL with the exe and sent him the whole thing in a Compressed Archive. I told him to extract the DLL and the Exe at the same place... But, as you predicted, it did not work... I tested it on my computer and it did not work either, I always have to know the full path to the DLL... How can I fix this ?
