Thanks again.
I rewrote this:
void CMyBitsDlg::ConvertLLtoBin()
{ LONGLONG value = 12345;
TCHAR mystring[sizeof(LONGLONG)];
for(int i = 0; i < sizeof(LONGLONG); i++)
mystring[i] = ((value >> (sizeof(LONGLONG) - i - 1)) & 1) ? _T('1') : _T('0');
mystring[i]='\0'; //added
AfxMessageBox(mystring);
}
And the answer is 00111001 which is 39 hexadecimal.
So something is wrong.
But the strange thing happening now is that I have an error memory reading message.

Almost correct. You need to change
TCHAR mystring[sizeof(LONGLONG)]; to
TCHAR mystring[sizeof(LONGLONG) + 1]; and instead of writing
mystring[i]='\0'; try
mystring[sizeof(LONGLONG)] = 0; I think that might help

Thanks again.
Ok the last version is
void CMyBitsDlg::ConvertLLtoBin()
{ //LONGLONG value = 12345;
LONGLONG value = 0xFF FF FF FF FF FF FF FF;
TCHAR mystring[sizeof(LONGLONG)+1];
for(int i = 0; i < sizeof(LONGLONG); i++)
mystring[i] = ((value >> (sizeof(LONGLONG) - i - 1)) & 1) ? _T('1') : _T('0');
mystring[sizeof(LONGLONG)]='\0';
AfxMessageBox(mystring);
}
And the answer is 11 11 11 11
Instead od a 64 times '1'.
Where the rest has gone ?

Thank you for yor time and effort.
I tried you edited code with a value of
0xFF FF FF FF FF FF FF FF (//16 F)
and it gives 64 1's which is the correct answer .
Thanks again.

hum, well, it seems that the code is printing only the LSB and is missing the 0b 00110000 00111001
did you try my code ?

Not yet,but I will and tell you about it.
Right now my head is spinning..dangerously!!

Thanks for the code you supplied.
I tried the one given by Joel Holdsworth,and it works perfectly well.
Here's the final version.
void CMyBitsDlg::ConvertLLtoBin()
{
LONGLONG value = 0xFFFFFFFFFFFFFFFF;//16 F
TCHAR mystring[sizeof(LONGLONG)*8 + 1];
for(int i = 0; i < sizeof(LONGLONG)*8; i++)
mystring[i] = ((value >> (sizeof(LONGLONG)*8 - i - 1)) & 1) ? _T('1') : _T('0');
mystring[sizeof(LONGLONG)*8] = 0;
AfxMessageBox(mystring);
}
The result is a 64 1's.

I'm so sorry to mess you around fardak! I'm really not thinking properly today! The problem is that sizeof(LONGLONG) is in bytes not bits. Change every reference to sizeof(LONGLONG) to sizeof(LONGLONG)*8, and everything should work out!

Hi,
I have alot of MFC and C++ Console applications & static library's.
I build all applications on Windows OS & main applications (console) on Linux (gcc gmake).
Which program do you guys advise to use to automated building so I can do building easily on Win & Linux? ant? Scons?
I realise this is not a general C++ question, but since you guys alsoo waste a lot of time building apps maybe anyone could give me some tips ..
Greetings,
Jens

I'm trying to finish a report on DSP (digital signal processing) technique increasing effect of sound. However, I can't find any documents teaching about this technique on almost the webpages. I hope your help...You can give me a link to a webpage, a ebook ,and anything else about the technique...thanks so much <vtalau@yahoo.com>

Hello,
I have developed Console based application . Now I want some code which will minimize the application to system tray and the process is running in the background.
I saw many codes but all are available for MFC or dialog based application .
can any one give me guidence or send me the code for the same.
Thanks in advacnce,
Rajat

In fact you don't want your console to be visible is it ?
See the : FAQ[^]

ya,
Basically its a continuously running process so i want it to minimize to system tray .
can any one please tell me how to get handle for the console window in vc++.
Thanks
|

I don't think this would be possible with a standard console application. I think (but I'm not sure) this is totally incopatible with the windows API and so, the taskbar is purely windows specific. I might be wrong but that sounds logical to me...
If you really need to do this, you will need to change your application and move it to a Win32 (or MFC) application

Hi..
I need to maintain a log file which will contain the time i started a playback.. and the time it ended.. What i have done is:
-> Get the current time and write it to log..
-> The code that takes care of sound playback..
-> Get the current time and write it to log..
The problem is .. both these times are same.. (the playback goes on for more than 10 secs..)
Can anyone help me out..
regards
pallavi

If you don't post the code, we won't be able to help you... Or at least the code that write the times in the log file.
|
|
|
|

Ya.. here it is..
CTime theTime=CTime::GetCurrentTime();
CString startTime=theTime.Format( "%H:%M:%S, %B %d, %Y" );
WriteLogFile(startTime);
m_pMyDS->Play();
CTime getTime=CTime::GetCurrentTime();
CString endTime=getTime.Format( "%H:%M:%S, %B %d, %Y" );
WriteLogFile(endTime);
.......................
Play() is a memeber function of class MyDirSound.. which plays the wave file.. The same code for writing time works fine with the recording of sound module ..

I don't see any problems with this code... Are you sure your Play function lasts for 10 seconds ? Maybe the sound is played in another thread and thus the Play function returns immediately even if the sound lasts for 10 seconds
[EDIT] A way to check this: just after the Play() function, display a MessageBox. If it is prompted when the sound is playing, that means it is played in a separate thread, thus that's logical you have the same time before and after the function. If it is displayed when the sound is finished, the problem must be elsewhere [\EDIT]

hi ..
Thank you..
You are right.. The the message is prompted when the sound is playing.. I am using Directx's DirectSound to play the wave files.. I tried defining and calling the WriteLogFile(..) function in the MyDirSound class itself.. What must be wrong?..
pallavi

But what do you want to achieve exactly ?? Measure the time of the sound sample ?
You won't be able to do it like that. Because as I said, if it is run in another thread, you won't be able to access it (even in your MyDirSound class). The thread is ran directly inside the DirectX layers so you don't have access to it. But (fortunately  ) there is probably another solution: normally there is something you can find in DirectSound (I suppose, because I don't know DirectSound) that will let you know when the sample is finished. Something like a callback function you can set or something like that. But in this field I have no knowledge so you will need to look in the doc of DirectSound. But I suppose they provided a way to do it...
