I cannot seem to get the program to check the password properly, it either doesn't work. Or anything works

Have you considered isdigit(), isalnum(), isalpha(), isxdigit(), etc? It won't necessarily solve your problem (I've not looked to see what the actual problem is), but making it easier to read won't hurt.
gamefreak2291 wrote: if(password1[q]='p','a','s','s','w','o','r','d','\0'){goto end1;}
Is this supposed to do something?
gamefreak2291 wrote: }while(x=1);
Look at this line real close. Also, your i+1 and i-1 statements are not doing what you expect.
gamefreak2291 wrote: for(q=0;q<i;q++){cout><< password1[q];}
Does this even compile?

no, i have not considered the others, because it took long enough to get the ascii values going.

yes, that takes you to the end which prints that the password works.
DavidCrow wrote: }while(x=1);
okay, im looking at it. It does exactly what it is supposed to, that bit of code is only in the program at this point for debugging purposes, it allows the user to keep trying to get the correct password.
As for i+1, and i-1.. i++ and i-- was not working properly, I changed them to +1 and -i, then had them print to make sure they were working.
And of course it compiles. the reason why "for(q=0;q<i;q++){cout><< password1[q];}" is in the code is because password1[i] allows you to enter 25 characters max, and if you only enter 5 characters, the rest of them are filled in with null terminators. However, I don't want my password to be full of null terminators, so if i input 5 characters, i is currently 5, so i have q=i; then i fills out with the rest of the array with null terminators. Then the program prints password1[q] from 0-5, which is really like printing password1[0], password1[1], password1[2], password1[3], password1[4], and password1[5]. I previously had the program print the entire array however it was over lapping on multiple tries, so now it only prints the needed numbers.
Thanks again for the help

I suspect that line should read
if (0==strcmp(password1, "password")) { goto end1;}
That's how you compare two strings, anyway.
What you've done is assign 'p' to the q'th character in password (probably overwriting the null terminator, I suspect). The rest of the expression is repeated application of the comma operator[^].

Hi,
if you are using windows as your operating system, when right click on a file, there is a menu for "Open with...", and then in side that menu, there is a menu for "Choose program..." When you select "Choose program..." a dialog with the name of "Open with" pops up. In there you can choose programs from "recommended programs" or you can choose programs from "other programs" section.
I am wondering how does Windows know what the recommended programs are?
also if somebody was to write or manipulate a diagram or program that shows recommended programs for a file, how would this be written in c++ code?
the compiler im using is vc++ 6.0's compiler.
thank you guys very much in advance.
I appreciate your help.

Have you looked in:

Create a File Processing System which allows for Random Access to Binary Files. The System should manage a file with a maximum of Ten (10) Records. A Record should consist of the following: (1) First Name (2) Last Name (3) Age (4) Sex (5) Salary(Use appropriate datatypes for each field.) The System should provide a menu which enables the user to: (1) Add (2) Delete (3) Modify, a Record.

Hi,
I'm trying to write a wav file to the sound card, but how are you supposed to do this? You can find various libraries to play all kind of music but what's hidden behind those libraries?
Basically, what should I do to directly send data to the sound chip? I can't find much information about this...
Thanks,
Tony

That's again an API. Is there a way to do something like fopen("soundcard","w") ?

AFAIK, you can't (unless you go in kernel mode).

Well I was trying to write a MP3 player I could easily port to the Nintendo DS by going very low level (ie: fwrite to the sound card). But well, if can't speak directly with the sound device I guess this isn't going to work.

Anything like an "fwrite to the sound card" just plain isn't going to work. Sound cards, like graphics cards, require data to be passed in the right way, and to the right buffer addresses etc, which is why there are drivers and APIs to help you do this.
I'm a game audio programmer, working on PC at the moment, but I've written systems for most consoles in the past - unfortunately not for the DS, so I can't give you specific advice, but it too will have a specific API which is how you should send the audio data and control information to the hardware.
In fact a quick google turns up lots of hits for DS homebrew audio (e.g. here) and the interface looks pretty simple. You should be able to get sounds up and running reasonably quickly using that.
There are three kinds of people in the world - those who can count and those who can't...

i need to increment the string value in VC++ 6.0 MFC dialog based application.
if the value of the string is 60 then it should get increment to 61. how can i achieve that. The string would contain number only.
Pl suggest.

I can not define that variable as int as i would need to store the variable value in txt file using CStdioFile. Using this class, it does not allow to store "int" value.
*********** EXAMPLE ****************
int m_barNo;
cfile.WriteString(m_barNo);
****************************************
if i try to store the int value using WriteString member function of CStdioFile, it gives an error as below "error C2664: 'WriteString' : cannot convert parameter 1 from 'int' to 'const char *' "
Hence i would need to increment string..could anyone suggest how do i proceed...

sscanf should do the trick no?
|

You first have to convert it to an integer (how to do it depends on what you mean by "string" exactly), increment the integer and then convert it back to a string.
