Search CP for synchronization-type projects. Google is also a good source.

iReturnValue = ::GetDiskFreeSpaceEx(drives,
(PULARGE_INTEGER)&i64FreeBytesToCaller,
(PULARGE_INTEGER)&i64TotalBytes,
(PULARGE_INTEGER)&i64FreeBytes);
TCHAR *lptotalbyte=NULL;
TCHAR totalbyte[100];
lptotalbyte=_ui64toa(((PULARGE_INTEGER)&i64FreeBytesToCaller)->QuadPart,totalbyte,10);
i used this
in my system it is showing me wrong result
if i try in other sys it is showing 0

Works for me. I get zero if I try it on a CD drive with no CD - GetLastError() returns 21, Device not ready.
I'd check what GetLastError() returns after the call to GetDiskFreeSpaceEx to see what the problem is.
 Pssst. You see that little light on your monitor? That's actually a government installed spy camera. Smile and wave to big brother!

Shouldn't this be:
_ui64toa(i64FreeBytesToCaller.QuadPart, totalbyte, 10); sunit5 wrote:

How are you verifying this "wrong result?"

First call GetDriveTypeInfo and then GetDriveVolumeInfo. The latter will return data such as volume serial number, total disk space and free disk space

Hi All,
I have a template class CustomList derived from MFC CList<ARG, ARG_TYPE> so that I can customize the serialization of the class
In .h file
// -------
template<typename T>
class CustomList : public CList<T,T>
{
DECLARE_SERIAL(CustomList)
public:
CustomList(): CList<T, T>()
{
}
virtual void Serialize(CArchive& ar);
};
In .cpp file
if I write
IMPLEMENT_SERIAL(CustomList, CList, 1)
I get a compiler error saying use of class template requires template argument list.
My question is how do I write IMPLEMENT_SERIAL macro so that my class is compiled correctly
Thanks

I guess, there is no .cpp file for template class. It should all be in the .h file itself.

Hi to you,
I'm looking for a way to stream audio-outputs over a local net. So first I have to program a server, which listen the wav-output and secound I have to make a client which access data from the server using ftp. At the end, I can hear the same music over several floors using wlan. Could everone help me to realise this?
Thank you!
Meinhard

You canuse WaveOut And WaveIn API,s for in/out Audio.
UDP is The the suitable WAy to transfer Voice DAta,
You Must Use RTP_Real Time Protocol To Syncronize Source
and Destination,
This is Simply Works!!!!

Synchronization does not make sense here, because it can't be synchron (network delay!) and you only have one stream.
Don't try it, just do it!

FTP is a file transfer protocol, you can not use it for streaming!
Either use TCP (which is easier to handle) or UDP!
The way the whole thing works is quite easy.
You can either send uncompressed data (WLan should be fast enough) or better use compressed data if you have many streaming clients or the connection is too slow.
For that case I personally wouldn't use RTP because it is difficult to implement if you don't want to use the live library or any other RTP library.
Since WLan normally is a reliable network I propose you use TCP.
Before streaming transmit the settings of the data to the client (sampling rate, bits per sample, ...).
The streaming is easy then:
-create a directsound buffer (should be big to prevent lags!)
-decompress (if compressed)
-load the data in a (big) directsound buffer.
-after the buffer gets full the first time, you should run it.
Don't try it, just do it!
