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!

Why would anyone want to hide a modal dialogbox? A modal dialogbox remains the active window, until it is closed (for a given application). If you need to hide it for some reason, then it should be modeless.

Yeap, You are Right.

May Be, But Modeless Dialog Box application need a parent application to run it, So better idea would be to make Hidden Dialog Box application.

Hello everybody!
I am using VS .NET 2003, trying to use axWebBrowser COM.When I draged and droped the axWebBrowser control from tool box to my windows form it added the references for SHDocVw and AxSHDocVw also. I compiled it, it compiled fine but when I ran my program it gave me a run time error:
An unhandled exception of type 'System.ExecutionEngineException' occurred in axinterop.shdocvw.dll
just to be on the safe side I have added "using namespace System::Runtime::InteropServices;" in my form's .h file but still I am getting the same error. For axWebBrowser I have wrote only this code:
1 String* url = S"c:\Test.XML";
2 axWebBrowser1->Navigate(url,0,0,0,0);
All I want to do is to display a .XML file in browser control which I did in my MFC application with the same control and with the same way as I have mentioned above.
Please help me!!!!!!

NOTE: I posted this on the 26th and received a great response in the form of e-mails from potential testers. However, I need roughly 4 more. The Developer Test Release comes with full documentation and source code, and weighs in at 68 Kilobytes (zipped).
I'm looking for any C++ developers interested in testing a new XML library focusing on a simplistic public interface. Developers of almost any skill are welcome to submit a request. Either e-mail me directly or leave a message along with your e-mail address in this topic. A lot of people have expressed a great interest in the project, and I along with them, believe it'll create a massive impact in the world of Open Source.
Just send the e-mails to skonen@gmail.com . Anybody who is interested in giving it a try needs to be proficient in English and have no fear with expressing their opinions.
