How can I send information and receive from external command prompt from my program??. I want to run an external command prompt, a code that's is not mine, to send information to this command prompt, then make my program hit enter at the command prompt and then receive back information from the command prompt.
View 5 RepliesI am looking to make a program for C++ that has a GUI other than command prompt. The program I am trying to create will ask certain questions and display the results at the end after all questions are asked and have 2 copies of the results one over the other that can be printed as a receipt. Basically I am wondering can I do this using C++. Also I want another GUI other than command prompt as well. Something close to what windows uses if possible.

I don't know if this is a bug in Winsock or the .NET Framework but i need to fix this or workaround. Recently I was working on a networking class and this error is breaking everything.
If you add Thread.Sleep(1) after Send() call then "TCP Bug detected" doesnt get executed but its not a reliable fix.
I'm trying to understand winsock with c++. Let's assume I have a 2 working applications, one is the client and one the server:
Client: I can enter a command, for example chat or filetransfer, it will then switch into this specific mode where I can enter commands like uploading a file, send a message etc.
Client
Code: ....
while (rc != SOCKET_ERROR) {
printf("
#");
gets(buf);
if (strcmp(buf, "CHAT") == 0){
// start chat mode

I'm in a recv/send loop and I'm using streams...so basically all the data is being sent/received there. Now, if I want to upload a file, I send a FILETRANSFER String to the server. Then I will probably need another loop that receives file requests from the client. The server will need more details about the file, like the path, name, size...
Now, my question is, what's the best practise for something like that? I'm having problems understand how I can send 3 different values from the server to the client and how he will receive them in the right order store them in variables. And also, after sending something to the server, in some cases, the client will have to wait for the server to answer.
Is there a good example of a similar application?
I am trying to make a streambuf for a socket, which will use either WinSock or POSIX sockets depending on OS. I understand about how to send and receive data via sockets, but I don't really understand how to put that into a 'streambuf'. What functions do I need to override?
View 7 Replies View Relatedwhen I want to use the same socket connected to the host to send() and recv() for the second time, recv() will return 0 without anything in buffer. Basically I am doing:
1. connect to the website
2. send packets
3. receive packets
4. send packets again (I think this one is working since it's not giving me SOCKET_ERROR)
5. receive packets again (this one is returning 0 so as "connection closed")

as you can see, I have sock2, which when I use for second send/recv it's working fine, however I will do more communication, and having sockets for all of that and connecting them.

my C++ console application should be like a command prompt. There are "command lines" to execute in the command prompt.Here are my main prompts for spotlight:

If I compile code which uses cin using the command prompt, then run the compiled program a new window opens when it reaches the cin line of code, for the input. If there is no cin used then all printing happens in the original window. Is there a way to stop this behavior of the opening of a new window?

I have created a MFC dialog based application. Now I want to implement such a functionailty that I will be closing my application through command prompt.

The problem of this code is when you put in the names(via cin) and press enter command prompt will disappear. What should I do so that Command prompt will not disappear after I input some names? I mean it disappears without you pressing a key.
