How to delete decimals and dot for decimals for double x with string.format(...,x)?

CString a;
double d = 5.0000;
a.Format("%d", (int)d);

SDK 6.1 defines some function signatures a bit differently than the Platform SDK that ships with VC++ 2005

WINOLEAPI  CoInitializeEx(__in_opt LPVOID pvReserved, __in DWORD dwCoInit);

If there is such a trick, I was thinking of using the new function signature for the newer SDKs while still letting the the people without the windows sdk 6.1 compile

#include <Windows.h>
#ifndef CONST
#define CONST

#include "ntverp.h"
#if !defined(VER_PRODUCTBUILD) ||  VER_PRODUCTBUILD < 3790

Isn't there an issue regarding threads and access to process-wide variables/data

Will I be able to kill a thread, while its in the middle of doing some kind of processing, from the main thread?

TheScientistIsDead wrote:

And can I change the flag's status (if quit is posted after I initialize the new thread)

// we have a thread handle, hThread and a shared LONG variable lQuit which is zero until it's time to quit
InterlockedExchange(&lQuit, 1);
::WaitForSingleObject(hThread, INFINITE);

// do stuff
if (lQuit) ExitThread(0);
// do some more stuff
if (lQuit) ExitThread(0);
