Or you can try :
cout.flush()
~RaGE();

HELLO!
PLEASE HELP ME!
I'm new in C/C++ programming.
And i have a problem:
here is the code:
char ch=fgetc(filein);
char s[20]="";
Now what I want is to put in string s the value that is the ord(c).
Example:if c is 'a' then I want put in s value "97".
This part of my code is written in ANSI/C language.
How can I do this?
Thank you very much!

I assume that ord(c) should return you the ASCII value of char c (maybe I misunderstand you). Therefore,
char c = 'a';
is equivalent to
char c = 97;
Then to get a string like "97", I would recommend using sprintf, as explained in Mike's FAQ on this link.
sprintf ( s, "%d", c );
Hope this helps.
~RaGE();

I am quite a beginner myself, but I think u can use pointers to do this.
Something like:
char *ptrs=NULL;
char s[20]="a, c, d, f, l, m";
ptrs=&s[3];//pointer points le address of s[3]
printf(" %d\n", s[3]);//should print the address
*ptrs=63; //value of pointer is 63
printf(" %d\n", s[3]);//should print 63
I think this is not correct, but might give you ideas.

What is an infinite return value?

I have a problem that a Dialog shouldn't be left via pressing a key. I have no default button on this dialog, but pressing ENTER results in leaving the dialog with a positive result (OnOK).
Is there a way to prevent the dialog to leave when pressing ENTER without ovverriding the OnOK method?
|
|
|
|
|
What does ur default implementatino of OnOk() event do ?
If its not doing anything you can very well override it and dont call the baseclass OnOK.

Implementation of OnOK() is displaying an error message if the validation of the dialog fails.
So this is not the solution I'm looking for, because I want to prevent the execution of OnOK() and doing the validations.
|
|
|
|
|
if you disable the OnOk call then when will it be ever called and validation will be performed ?

OnOK() is called explicitely in the method which is called by pressing the "Leave" Button.
|
|
|
|
|
aah! got you..
Instead of calling OnOk when leave is pressed, instead let the Leave button call another Event that will do the validation, then implement OnOk normally to disable the enter key.

I agree it's a solution, but I think this is a bad one. Thanks.

Nope its not a bad one, its very much a accepted logic.

Then go for capturing key press

I have encountered the same problem before, but I did not really fix it. I just made some work around with it. What I did is I used a different command id for the button. I did not use IDOK. Resulting the command ID to be unhandled. Hope this help.

What do you have against this? It's the natural thing to do. Read here for a good explanation.

Hi,
My application uses ReadFile() API in asynchronous mode.
While in the Debug mode it reads 29 bytes from the port ,
it reads only 7 bytes in Release mode.
Is there any known issues with the use of ReadFile(),
or is there a work around for this issue.
An early reply would be very helpful.
Thanks!

difference of working in debug/release mode is usally because some variables were not initialsed properly before it is used.
If any structure is passed to the api makesure that you zeromemory it.

This may have to do with timing issues. As the code executes more quickly in release mode, there may not be enough time for the port to receive as many bytes when the call returns.
onwards and upwards...

can anybody guide me to write c or c++ code to play an raw audio files
thank you

create a buffer with the characteristics of the raw sound (srate, bits etc) then copy the data in and start playing it.
Don't try it, just do it!

i didn't get what your are trying say. please an you be more specfic.
|
|
|
|

I propose that you use DirectSound.
You create a buffer with the specifications of the wave data (sample rate, bits/blocksize, ...), then you lock the buffer, copy the data in, unlock it and then start playback. read the sdk for further information.
Don't try it, just do it!

Here's what I do in Visual C++ 6.0.
1. Import the .wav file and name it something you'll remember, like IDR_BADBEEP.
2. Add #include "mmsystem.h" to the top of your file.
3. In Project/Settings/Link, add Winmm.lib
4. In the actual code where I want the sound effect to play, add:
PlaySound(MAKEINTRESOURCE(IDR_BADBEEP),GetModuleHandle(NULL),SND_RESOURCE | SND_ASYNC);
This will play the sound effect until the program is shut down, the sound effect is entirely played, or another sound effect is started. It's easy and works.
