That's the problem.

If you ask a specific question like "How can two windows objects communicate with each other", I'll say "Post or send registered window messages".

But to a generic question, only a 'generic' answer can be given. Narrow down your query, say me what exactly are those objects that needs to communicate with one another. And for God's sake what can a "module" possibly mean?! You seem to be using that term very frequently.

Please be specific.

Modules are again different projects....(whose output can be dlls)
By objects, I mean simple objects of some classes...eg:
class Message1
{
....
}

Message1 *objPtr= newMessage1();

This Objptr, i should be able to pass with another modules

Please read Hooks and DLLs by Dr. Joseph Newcomer[^]

I recommend that you read up on the articles related to DLLs for beginners. There's plenty on CP, please do a search.

Please be clear whether you want to know about the class level design i.e Detailed design or component level design, i.e Architecture design.
I hope you are looking for both then please have look at
Design patterns, please check this, either study with Eric Gamma's text or just check [^]
These topics will surely help you.

thanks a lot for your reply...I will look in thorough all these
I was looking something like class desing....
example, make all modules as a dll....export a class pointer ...get the handle and get the functions of that module....etc etc

Linking MFC/C++ code via lib wrapper into C application without MFC support

I've got MFC/C++ based code.

I've wrapped it in static lib (C++/MFC also) providing in .h file e.g. single function that does call to the code.

The lib wrapper .h file contains only single function declaration without any hints to C++ or MFC

int DoSomeTask();

I added that lib with .h file to C console application without MFC support using only standard win libs

I can compile project without problems but I've got unresolved externals during linkage. What is the problem?

error LNK2001: unresolved external symbol _DoSomeTask() main.obj

If this function is in the C++ library then its exported name will be in the 'decorated' format - I can't remember the exact rules for this. You will need to find the name from the lib file and use that in your linker options to map to the correct exported name. You could also check the LIB options to see if you can export the undecorated name from there.

You should either install the VC2008 redistributable package[^] on the target machine or statically link your exe to the MFC and C runtime libraries (you have to modify these in your project settings).

you need to make a release build (without debug dlls). Static linking is the easisest way to make it. Thumbs Up | :thumbsup:

The program will work well when you use the static c runtime libraray.

you can use memu "Project"->"settings(Alt+F7)", click "complie" in dialog, then choose then choose "Code Generation", see the "use run-time libraray", choose "MultiThreaded" or "MultiThreaded Debug", rebuild project to apply changes.

How to Lock Other Process's Offset Address of the values ?

Hello Everyone !

now I want to revise the offset address of the value in other process.

just like this :

void C***Dlg::LockData()
{
	HWND	hWnd;
	HANDLE	hLink;
	DWORD	dwPid;
	int		dwData=10000;
	int		nData = 4000000;
	hWnd = ::FindWindow(NULL,"title");
	if(hWnd == NULL)
	{
		MessageBox("the game is not running ！");
		return;
	}
	GetWindowThreadProcessId(hWnd,&dwPid);
	hLink = OpenProcess(PROCESS_ALL_ACCESS | PROCESS_TERMINATE |
		PROCESS_VM_OPERATION | PROCESS_VM_READ |
		PROCESS_VM_WRITE,FALSE,dwPid);
	if(hLink)
	{
		WriteProcessMemory(hLink,(LPVOID)0x00B05542,&nData,2,NULL);
		Sleep(50);
	}
	CloseHandle(hLink);
	CloseHandle(hWnd);
	MessageBox("successed ！");
}

What values, and what do you mean by readonly? In either case whatever you are trying to do here looks extremely dangerous to me.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
