I have a DWORD and i want to convert it into a time format.

char buf[0x20];
DWORD dw = 0x41107ECE;
time_t t = dw;
struct tm * ptime;
ptime=gmtime(&t);
strftime(buf,0x20,"%Y/%m/%d %a %H:%M:%S UTC\n",ptime);
printf(buf);

Finally, your technique will not work. LoadResource returns nothing that LoadString can consume.

HRSRC hres = FindResource(NULL, MAKEINTRESOURCE(IDS_SOMESTRING), RT_STRING);
DWORD dwSizeRes = SizeofResource(NULL,hres);
char *p = NULL;
int result = LoadString((HINSTANCE)&__ImageBase,AFX_IDS_APP_TITLE,p,0);
std::string s(p,dwSizeRes);

std::string load_string_from_resource( HINSTANCE app_instance, unsigned string_ID )
{
    char buffer[ 4096 ];
    unsigned bytes_copied = LoadString( app_instance, string_ID, buffer, sizeof( buffer ) );
    if( !bytes_copied )
        throw std::runtime_error( "Resource not found!" );

    return std::string( buffer, bytes_copied );

std::wstring LoadString(HINSTANCE hInstance, UINT uID)
{
	LPCWSTR pString;
	int res = LoadStringW(hInstance, uID, (LPWSTR)(&pString), 0);
	if (res == 0)
		return std::wstring(); // No such string.
	return std::wstring(pString, res);
}

Very nice and useful

ReturnType SomeClass::SomeFunction(SomeParams)
{
    char buffer[1024] = {0}; // this a stack allocation
    // any code ...
    return ReturnType::SomeValue;
} // buffer is deallocated here
