Hi all,
I am trying to run one console based application,
Where i reading a argument from command line.
If i press ENTER ,i am writing the sane to the command line.
How can i print the same without pressing ENTER.
Can i execute the second printf without pressing ENTER
This is the code i am using
int main(int argc, char* argv[])
{
int aNumber;
char aChar;
printf("\nEnter a number:");
scanf("%d", &aNumber);
printf("\nThe number entered is %d\n", aNumber);
return 0;
}
Thanks
Sharan

On Windows, you can utilise the _getch function, which is exposed by conio.h. On *nix, you can use tcsetattr to turn off canonical mode, which is exposed by termios.h, which'll offer immediate feedback when reading.

Hi , Use this modified code.
Modified code,
#include <conio.h>
int main(int argc, char* argv[])
{
int aNumber;
char aChar;
printf("\nEnter a number:");
scanf("%d", &aNumber);
printf("\nThe number entered is %d\n", aNumber);
getch();
return 0;
}

Hi,
try to run this program from the windows command prompt..

We have an application developed using MFC in Visual Studio 6.0. which is a client-server based architecture using TCP/IP Sockets.
The server application reads data from text files and binary (which acts as database). Based on the Network configuration, the client application that runs in various stations (PCs connected within the LAN Network) connects to the Server application. Exchange of data then takes place between the server and various number of clients that are connected to the server. All the communication happens using the TCP/IP socket protocol.
Now there is a requirement to convert the existing architecture to web based architechture such that the Server is installed in a remote PC. The clients from various geographical locations have to be connected to the Server.
Please provide me guidelines how to convert the existing architecture to web based architecture.

You need to convert your server into a web server using one of the web architectures available. If you are familiar with Microsoft products then ASP.NET[^] would be a good choice.

Hi,
First you need to convert your Server portion to a web architecture.You can use ASP.Net and SQL Server. Then develop the client in Visual c++ or something else, the client must communicate to the database.

Er, anyone else see a problem here?

So you can market it as 'Cloud' no doubt?
Just leave it as it is, it is already an internet based app and slap 'Cloud' on the box to fool the muppets and marketing types who use words without understanding what they mean.

The internet is based on TCP so at the basic level there is no difference.
The two factors that are relevant.
1. You must have a public IP. On a lan you probably have a private one. The public IP allows someone on the internet to address you. You might, but it is not required, also want to have a Domain Name. There will probably also need to be seem network infrastructure setup to route from the public facing hardware to the actual server. None of this has anything to do with the existing server/client code unless the client code does not allow a way to specify an IP/Domain Name (because someone hardcoded the IP.)
2. You MUST provide security. User/pwd should be sufficient as long as the pwd strength is sufficient. You might already have that in the code but if not it must be added.
Besides the above you might want to investigate SSL depending on the nature of the data that gets sent.

i have a string
login#user#1 username password
i want to trim login# and extract user#1 username password
i am unable to sole it using strtok
please help

Use
std::string::find_first_of() To find the position of
#. Then use
std::string::substring() to extract the string you required.
Code might look like this:
std::string test = login#user#1 username password;
size_t pos = test.find_first_of("#");
std::string requiredstr = test.substr(pos+1);

is there any way to do it using strchr

hey i am programming in C...can u give a sample code of how to do it using strchr(), strtok or any other function in C
|
|
|
|
|
|
yeah i know this but this does not work for the string
Login#User#1 username password if want to trim Login# and extract User#1 username password
|

You should be able to figure out what changes to the program needs to be made for it to work with your string.

I've provided you a link with source code. Use the formula
in the printf statement inside the while loop.
char str[] = "Your string goes here";
char * pch;
printf ("Looking for the '#' character in \"%s\"...\n",str);
pch=strchr(str,'s');
while (pch!=NULL)
{
printf ("found at %d\n",pch-str+1);
pch=strchr(pch+1,'s');
}
pch is the required string.

Use strchr() to find the first # character, and then you can use strtok() to split into the three tokens delimited by spaces.

After so many questions regarding strings, parsing and related stuff, don't you think it's about time to read some actual books or articles to learn all this? Or do you intend to keep asking for the rest of your life?
Seriously, the time you keep spending on low level programming questions like this would have been better spent by reading up and learning something by yourself. You are doing yourself and everyone else a disservice by asking questions without ever even trying to look something up and really understand the things you are dealing with.
Regarding this particular question, simply reading up on strtok would solve it, easily.

Have you tried something like:
char *pszSource = "login#user#1 username password";
char *pszPos = strstr(pszSource, "user#1");
int nLen = pszSource - pszPos;

I get these compile errors "warning C4129: 'N' character escape sequence.
I think I just did something dumb, because I have other lines that are fine in the same code block. I'm not really sure what to make of it.
L" /SAPWD=\"securePassword1\";"
but this line errors on \"N
L" /AGTSVCACCOUNT=\"NT_AUTHORITY\NETWORK SERVICE\""

return szParameters;

You have to escape the backslashes in the middle of the string, like this:
L" /AGTSVCACCOUNT=\"NT_AUTHORITY\\NETWORK SERVICE\""
|

I get it now, I escaped out the doublequote, but I didn't bother to look in the center. I was too busy looking at the doublequote.
It was a dumb mistake, Thanks for your help.
