You can use net time PC-B to get the current time of PC B.

hi all,
I have extrated audio from video and i need to store the extracted audio as .wav format.
I wrote the following code to save audio in .wav format.
void CWave::Save(CFile *f)<br />
{<br />
WAVEFORMATEX m_waveformat;<br />
m_waveformat.wFormatTag = 1;<br />
m_waveformat.nChannels = 1;<br />
m_waveformat.nSamplesPerSec = 7500;<br />
m_waveformat.nAvgBytesPerSec = 7500;<br />
m_waveformat.wBitsPerSample = 8;<br />
m_waveformat.nBlockAlign = 1;<br />
m_waveformat.cbSize = 0;<br />
<br />
f->Write("RIFF", 4) ;<br />
DWORD dwFileSize = 20000 * m_waveformat.nBlockAlign + 36 ;<br />
f->Write(&dwFileSize, sizeof(dwFileSize)) ;<br />
f->Write("WAVEfmt ", 8) ;<br />
DWORD dwFmtSize = 16L;<br />
f->Write(&dwFmtSize, sizeof(dwFmtSize)) ;<br />
f->Write(&m_waveformat.wFormatTag , sizeofm_waveformat.wFormatTag)) ;<br />
f->Write(&m_waveformat.nChannels, sizeof(m_waveformat.nChannels)) ; f->Write(&m_waveformat.nSamplesPerSec,sizeof(m_waveformat.nSamplesPerSec)); <br />
f->Write(&m_waveformat.nAvgBytesPerSec,sizeofm_waveformat.nAvgBytesPerSec)) ;<br />
f->Write(&m_waveformat.nBlockAlign, sizeof(m_waveformat.nBlockAlign)) ;<br />
f->Write(&m_waveformat.wBitsPerSample, sizeof(m_waveformat.wBitsPerSample)) ;<br />
f->Write("data", 4) ;<br />
DWORD dwNum = 20000 * m_waveformat.nBlockAlign;<br />
f->Write(&dwNum, sizeof(dwNum)) ;<br />
}
m_pWave.Save("c:\\temp.wav");
Everthing is working fine.A wave file is created in c:.
but when i play the wav file,the is no audio..wat is problem in it.
is that save function is correct?
do u need to add some code??
plz give me suggestions and idea..help me

Hi,
I think normaly Firwalls block ports not the creation of sockets, Am i right?
If this the I have opened a port on server side then the firewall will not allow it , but lets say i allow that port to be open.
On client side I only socket is create to connect to the server ip and port, I think this creation of scoket would not be blocked by client side fire wall to connect to server side application?
any idea / comments
Thanks
Regards.

I don't think u r right.
because all the internet application are served through only one port (80).

Is it possible for me to display the message box and let the nxt function to process while the message box remains displayed and the user cannot close it.
The message box will have to be closed after the function finishes.
If yes, how can I go abt doing it?
Another question is how can I display a dialog box ( using doModal() ) and perform a function immediately without User Interaction?
Thanks!!

You'll have to use modeless dialogs for that. Take a look at this article[^].

Override OnInitDialog and call the function there.

Hmm I mean doModal(), then call a function of that dialog class immediately after the dialog is being displayed.
Is it possible?
|
|

you can write your funtion in OnShowWindow ;
But still it won't fulfill your purpose as you want to call the funtion after the dialog is displayed.
In that case I have two options.
First in the OnInitDialog function you call SetTimer to set time say 1 sec.
Then call your funtion in OnTimer and kill the timer in OnTimer function.
Second method is that you create a thread to call your funtion.
and start the thread in OnShowWindow.

very bad idea...!!
consider the case where you init your dialog with a database which it connection is long to establish (at least more that 1 sec)... the program will behave badly.

Yes you are right , Its a bad idea, depending on the situation.
But the programmer know what he wants, and aware of the conditions. if the condition is according to you then we can use thread instead.
But I think still I can make it to work.
<code>
void OnShowWindow(){
SetTimer(....);
return;
}
</code>
second case
<code>
void OnShowWindow(){
SetTimer(....);
return;
}
</code>
It depends on when you set the timer.
But I still agree with you that its a bad idea.
But is one of the solution depending on the situation.

This goes against the concept of a message box. One way you could get this effect is to display the message box in another thread. It might be simpler to make your own modeless dialog however.

Delay MessageBox delays a short period of time before going to the next step of code.. But I would like to display the messagebox and continue the nxt step of code as per normal..
Am I correct to say that?

Create the ModelLess Dialog box!

Please have a look on Mauro Leggieri's Background Task Dialog[^] Good luck and keep the good coding!
