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!

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.

If it will work on Windows CE 3.0, we definitely could use it!

XML Dev<br />
-------<br />
<br />
Comments...<br />
<br />
- make the DevNotice.txt file wrap to ~80 columns<br />
<br />
[LoadDocument]<br />
<br />
- doesn't support the necessary character encodings:<br />
See http://www.w3.org/TR/2004/REC-xml-20040204/#charencoding for info<br />
<br />
- doesn't detect the appropriate file encoding:<br />
http:
<br />
- at a minimum, you should be able to load all of the sample files on<br />
this page:<br />
http:
<br />
- since you're trying to make this OS independant, you could use:<br />
http://www.unicode.org/Public/PROGRAMS/CVTUTF/ for your conversion code<br />
between utf-8/utf-16.<br />
<br />
[Other Stuff]<br />
<br />
Bug: Failure to check for empty/all spaces/invalid tag/attribute names.<br />
It's a problem with SetAttribute, AddChild, etc. <br />
<br />
i.e. pRoot->SetAttribute(_T(""), _T("a")); is allowed.<br />
pRoot->AddChild(_T(" ")) is allowed.<br />
<br />
- how do you set the XML declaration? (i.e. <?xml version="1.0" encoding="utf-8"?> )<br />
<br />
- I question the use of the text mappings. What's important is that you can<br />
handle reading Unicode files in an ANSI build, and vice versa. I would just<br />
store all the XML data using wchar_t/std::wstring. utf-8 files could be<br />
converted to ucs-2, and passed to the XML object. utf-16 files could be<br />
passed directly to the XML object.<br />
<br />
- Usage seems fairly logical and simple from the stuff I tried<br />
<br />
- Help file layout is very good. The only thing I don't like is lack of<br />
padding on the top and bottom of text in the gray boxes<br />
<br />

There are still a few more of you I need to e-mail the developer release to. I apologize for the delay but I've been rather busy working with Jack's suggestions. I am proud to say I have completed support for the standard encoding types and the conversion process is completely transparent to the developer using the class.
As for my GMail account not receiving every message lately, I'm not entirely sure about what is or isn't causing it. I can only hope it has nothing to do with my Google article which introduces a new class to avoid the official Google API.
I'll be sending the new and improved developer release to all of you very soon.

Hi all
I want to know if there is a way to refresh the window for the busy dialog. My dialog disappear and cover by the other windows that I open while it is working. The dialog is there working but doesn't see anything at all. How can I refresh the window so I can see the updating variables as well as other resource items.
Thanks
