Hi i m a c++ programmer no shifting to JAVA.
is it possible to perform operations like following in java?
or is there anything else i can do? like it would be good if i can add c++ code in java??Quote:
WriteProcessMemory
GetThreadContext
SetThreadContext
VirtualAllocEx
CreateProcess
ResumeThread
or anything else possible to perform these functions??
I know it's possible to create a new process in Java, see: ProcessBuilder
It's possible to suspend/resume threads in Java (provided you're able to get a reference to them), but these features are technically deprecated. See: Java Thread Primitive Deprecation.
It's possible to call C code from Java using JNI (Java Native Interface) or JNA (Java Native Access). There are various tutorials online, including a few on this site.

Why would you need to use primitive Thread operations? I think any time where that crosses your mind, you need to rethink your logic a bit.
Secondly, you can do some specific memory management using java.nio, for example:
ByteBuffer.allocate
ByteBuffer.allocateDirect
basically i want this to inject any program in to a running memory.... :)
No, it's harder to write a virus in Java (which is, good or bad, what it sounds like you're trying to do).Quote:

This VM is somewhat like a true O/S virtual machine in that it takes care of memory allocation, running processes (threads), and security. One part of that security is that you can't just write to anywhere in the Java VM nor can you write to just anywhere in the O/S memory. The Java process runs as a particular O/S user - it would be a very poorly done system for Java to run as a root or administrative user.
Remember also that Java is meant to be O/S independent. WriteProcessMemory is a Windows specific call and would not port well to Unix based O/S's nor to MVS on a mainframe. What you're trying to do is very O/S dependent and Java is not likely to be the best tool.
Now that sounds malicious...I wouldn't expect much help in the matter unless you prove otherwise.Quote:

My intentions are good otherwise i should have posted this in some hacking etc forum.... :D
Hope u will help me now
Well, I don't think Java is the best language for that, but as I see the problem there is one option. Call C++ by Java.Quote:
