So I'm using samurai's class to inject my dlls, I just had one question.

-How come the injection code works sometimes, while other times it just doesn't work at all

The error that always stops me is WriteProcessMemory not working correctly, any idea why it wouldn't work?

or you know, you could just debug it instead of expecting us to be psychic

also: GetLastError()

I sometimes have injection errors too: it always happens the first time after a reboot, and only once. After that it always works.
Is that also what happens to you?

Oh crap, sorry for forgetting to put the actual error

I get error code 1008 which according to this website

http://help.netop.com/support/errorcodes/win32_error_codes.htm

is:

1008 An attempt was made to reference a token that does not exist. ERROR_NO_TOKEN

The error always appears right after the WPM line.

I'm on Vista, 32, UAC disabled

What makes this weird is that sometimes it works perfectly, other times I can't inject anything at all with his code.

No exceptions are thrown btw to answer that question.

Since we don't know where the source you're using is, I decided to take a trek over to that crappy forum of yours. Having found it, I can tell you that your pinvoke of WriteProcessMemory is incorrect, and that checking the last error as a condition is bad form as when it is set it is not unset, meaning anything could trigger it. Therefore, you should fix your pinvoke and check the return value.

set the privileges with adjusttokenprivileges

How come I would be adjusting priveleges if the error is that there is no token?
