Debugging...
-
I am trying to make a very simple debugger. In fact, it always has to do the following: Open a program and pause the execution right away. // Like starting the debugger in VC++ with "Step Into" Then it needs to write some data into memory, I know how to use WriteProcessMemory() for that Then it needs to resume execution, and if possible have the debugger close without closing the new process. I'm not very familiar with the debugging functions, only Read and WriteProcessMemory, so if someone could provide sample code to do the above, or at least explain how I can open a process and have it paused right away, and how to resume the execution and close the debugger without closing the process. Thanks for any help! :-D

You can use
CreateProcessto execute the exe withCREATE_SUSPENDEDstyle this will start and pause the exe at the begining, you can later resume the process.
C makes it easy to shoot yourself in the foot; C++ makes it harder, but when you do, it blows away your whole leg

Get the Debugging Applications - Ms Press by John Robin. The book does show on how to develop one simple debugger with some sample codes. Sonork 100.41263:Anthony_Yio

Thanks. I got it working, but there is one thing that would make it a lot easier... Is there a way to get the address of the Entry point of the program after using CreateProcess with CREATE_SUSPENDED. I know it stops it at the Entry point, but I don't know how to get the address of it. Thanks again.
