Hi all i am using the method InternetOpenUrl with a callback
then i can tell when status complete that proxy authentication is needed
in MSDN it says to call InternetSetOption with the proxy user name and password and then call resend
the problem is that i don't know how to call resend because if i call InternetOpenUrl again then it says again when complete that proxy authentication is required
???

the trick was not to call again internetopenurl (since it opens a new session), but to call httpsendrequest...

Hi.
I am trying to stream audio with waveOutWrite(). I have a server which gets continuously packets with voice data. What I do is playing data with waveOutWrite() and then in callback function when the playing is done I call to waveOutWrite() with next packet (there is no such situation that there are no ready packets). The problem is that because of a very small size of packets and so a large amount of packets there is a small gap between them, so I dont get a clear playing. How can I stream it more smoothly?

When do you start to play a new packet?
In general you should use at least two buffers where one is filled and queued for play with waveOutPrepare & waveOutWrite while the other buffer is still playing.
I prefer 5 or more buffers for that because also with 2 buffers you hear sometimes a gap.
Maybe you could post your callback or the function where you prepare and write.

Could you give me your code on how to play multi buffers with waveOutWrite?

I would take a look at this CodeProject-Article.
It helped me to work out how to handle audio playback.
Hope that helps.

As well as multiple buffers as suggested above by Covean, you should try to use larger packets, to reduce the amount of unnecessary processing you're doing. Using very small packets will be more likely to cause you problems, as you're experiencing.

hi
can the tutorial in learn vc++ 21 days about socket programming work without the code related to SetParent(this). I am implementing the same program but not in a dialog or a view class.
thanks

Yes it will work fine until the GetParent() call (i.e. dumb question-dumb answer)...

well u mite think its dumb.
The original code goes like this
void CMySocket::SetParent(CDialog *pWnd)
{
m_pWnd = pWnd;
}
<pre>
I wanna modify it to
void CMySocket::SetParent(CWeigh *pWnd)
{
m_pWnd = pWnd;
}
Weigh is a class created for my program which has no base class. I have made all the declarations correctly. When i add the header file of CWeigh Class to the header file of Socket class i get errors.
Plz help, and hence the question of eliminating SetParent

OK, things are getting a little better now.
In the original code (you have it, I haven't) the CMySocket::m_pWnd member is possibly a pointer to a CDialog object while you're passing a pointer to CWeight one, hence (probably) the compile errors.
To get better help, you should post, at least, the exact error message and the line of code wherein the error occurs.

I have included the header file for my weigh class as follows
#include "Weigh.h"
#if !defined(AFX_MYSOCKET_H__57CF680B_2F58_4A22_81FF_1A8C4841E38E__INCLUDED_)
#define AFX_MYSOCKET_H__57CF680B_2F58_4A22_81FF_1A8C4841E38E__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
I have declared the pointer and the setparent class as follows
void SetParent(CWeigh* pWnd);
CWeigh* m_pWnd;
I am getting errors which state
error C2061: syntax error : identifier 'CWeigh'

It looks like you included Weigh.h inside a header file (usually you include header inside source, i.e. cpp files) and that you've included it before the multiple inclusion guard (the block starting with #if !defined(...), ending with #endif), hence your compilation error may occur because of header multiple inclusion. Do the following change (if you really need to include the header inside the other header... )
#if !defined(AFX_MYSOCKET_H__57CF680B_2F58_4A22_81FF_1A8C4841E38E__INCLUDED_)
#define AFX_MYSOCKET_H__57CF680B_2F58_4A22_81FF_1A8C4841E38E__INCLUDED_
#if _MSC_VER > 1000
#pragma once
#endif // _MSC_VER > 1000
#include "Weigh.h"

Hi ALL,
Which one is easier to develop a GUI.Is it VC++(MFC) or is it VC++/CLI(i.e.VC++.NET).Please advice.
Thanks,
ashwath.

I would not use Managed C++ to build a GUI. I would use instead C#. That said, MFC is quite powerful (nothing is really easy when talking about Windows programming).

Agree that one should not use Managed C++ for building GUI. Managed C++ is mainly for compiling legacy C++ code, where performance is not an issue. Or wrapping native C++ code as standard .NET classes.
I would choose Winforms/C# over MFC/C++.
|

|
|
Starting from what level of development skills ?
IMO, they are both equivalent, have a look at your requirements and match them to what MFC and .NET (forms) have to offer.

It's also depends a lot on the UI features you want to develop. Could you elaborate a bit on that part ?

If you have experience in .NET, you could choose .NET because it's easier. I'd personally choose MFC, because I've been using it to build GUI for a while and I find it convenient for my purposes.

Hi expert,
I've experience in Paint, should I use it?

Why not? But, I must warn you that it might take longer than expected.

Well, could always draw in paint the code you want to write, then use OCR to convert it to text and paste it to your compiler, but I'm not so sure that it is the most efficient solution

I think you should use C# or VC++/CLI, Because MFC is dieing. Fewer and fewer people are using MFC.
