Hello _Russell_,
What you need is known as "explicit template specialization". Define each specialized version of "void fun()" as follows :
void CMyClass<int>::fun()
{
str.Format("%d", var);
}
void CMyClass<float>::fun()
{
str.Format("%f", var);
}
Best Regards,
Bio.

Thanks friends,
It works.
But let me know if are possible other solutions, expecially if exist a way similar to the way that I used in the first message (if it exist then in some cases it can be a very fast way to write code!)
Have a nice code day

Yes, you can use a policy-based design as one way to solve this:
template <class T> struct format_string
{
LPCTSTR get_string() { assert(false); }
};
template<> struct format_string<int>
{
LPCTSTR get_string() { return _T("%d"); }
};
template<> struct format_string<float>
{
LPCTSTR get_string() { return _T("%f"); }
};
template<class T, class policy=format_string<T> > class foo
{
public: void fun() { CString s = policy::get_string(); }
};

Hello
I create a CSocket object then I post it to a thread but when I post it to thread, posted object(pointer) is not valid in thread
how can I create a socket out of thread and send it to thread?
thanks

Your question does not seem to be very clear.
How do you create the CSocket object? If it is like:
CSocket sock;<br />
...Initialize it etc.<br />
CreateThread(... , (void*)&sock...);
Then it is not going to work, because the object is being created on the stack and will be destroyed when the calling function exits.
Create it on the heap etc:
CSocket* pSock;<br />
pSock = new CSocket;<br />
...Initialize it etc.
Then send it to the thread.
Hope that helps.
this is this.

Many types of MFC objects can't be passed between threads becaues MFC keeps per-thread data structures. Pass the SOCKET handle to the thread then call CSocket::FromHandle()

By using Winsock, 2 network cards in a single PC connected through cross over cable, is it possible to do file transfering using these 2 network cards? I would like to force the file transfering from network card #1 to network card #2.
Thanks.
|
|
|
|
|
I have not tried it, but I think you could assign different IP addresses for use with each of the cards? My guess would be to run one application and bind it to one IP address and run another application and bind it to the other IP address, and then there should be no problem.
this is this.

Hi friends
i have a windows service which is updating time data in a file (like 01:20). When I change system time in Windows Date and Time Property , the timing changes are reflected in the file by my service. But I change the time zone tab, the modified time it is not reflected in the file by my service. Windows Time is changed in SysTray icon. Why is not changed in my service ?  i use localtime()

I think it is because the service is independent of the current logged-in user. You know that services cannot even read registry values in the HKEY_CURRENT_USER hive.
So my guess is that it (the service) does not care whether you change the regional settings or not. Because it does not even know you (the current user) 
this is this.

Little Exception you can read it from HKEY_USER hives

Hi,
Iam developing an Windows based application, where there are multiple browser windows opened. And when i press CTRL + TAB it shifts to the previous browser(the way in which ) it works in Visual Studio. But my question is:
1) Does windows (i mean the MFC or MFC's API)itself remebers this (the previous active frame window )?
2) If yes, then how and where is this information stored by the window so that i can dosome processing on it?
thanks in advance,
KAB

AFAIK, The OS manages this for you.
Aravind Badrinath Krishnan wrote: 2) If yes, then how and where is this information stored
I'm not sure it stores it so you can get to it. (If you find otherwise, please let me know)

Window activation (OnActivate in MFC, or WM_ACTIVATE) is probably a good place to start

Hallo
how do i copy a selected CDC regions to a bitmap variable??
(this are some complex expensive drawings that will not be changed very often.)
Or is it cheaper to save the the drawing as a MemoryDC??
THX

Hello
Like this
HDC hdc=CreateCompatibleDC(GetDC()->m_hDC);
HBITMAP hBit=CreateCompatibleBitmap(GetDC(),Width,Height);
SelectObject(hdc,hBit);//hBit=(HBITMAP)SelectObject(hdc,hBit);
BitBlt(hdc,0,0,400,400,GetDC()->m_hDC,0,0,SRCCOPY);
SelectObject(hdc,hBit);//hBit=(HBITMAP)SelectObject(hdc,hBit);
