Accessing a process memory from a thread

Question

I access another program's memory from my main window code, that looks like this:

	HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, NULL);

	if (Process32First(snapshot, &entry) == TRUE) {
		while (Process32Next(snapshot, &entry) == TRUE) {
			if (stricmp(entry.szExeFile, processname) == 0) {  
				HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, entry.th32ProcessID);

...

and it works fine but when I move it into a function that is called as a thread using CreateThread() - the code stops working.

Do I need to somehow modify the code so it could work from a thread?

Thanks!

Answer 1

At which point of shown fragment does it stop working? Maybe you lose the first process returned by Process32First.

Answer 2

What you mean by not working. You can debug code and check that at which point it is stopped working. If you give more information we can help you better..
