injecting code into a process

[Killboy]

You don't really have much of a clue when it comes to the PE format, huh

Coding around bugs and missing features if you're not familiar with PE internals is a bit of a hassle if not impossible

Dunno, read up on the specs of the import table, take a look at FixImports and implement what I told you

That's as much as I can help you.

Maybe grab sources of some of the few open source PE tools (PEEditor, TitanEngine)

can anybody make a simple " write new bytes in memory with injecting DLL"
exampe

adress. 0x0043256

bytes: {0x90, 0x90}

writeprocessmemry ....

 

with inject method

If you are injected you can just use memset given the two bytes are the same and together:

memset( (LPVOID)0x0043256, 0x90, 2 );
