why this code works only for file of smaller data. When I try to send for istance a image, the image arrive corrupted.
Client:
//read all file
byte[] vett = File.ReadAllBytes(s);
//read filename
[Code]....
I want to send data from a file via winsock. The problem is that the only first line in the file is send.
Client
#include <iostream>
#include <winsock2.h>
#include <fstream>
#include <string>
#pragma comment(lib,"ws2_32.lib")
#define SERVER "127.0.0.1" //ip address of udp server

I use SmtpClient's SendAsync method,when after send mail, i delete the file ,tip The process cannot access the file because it is being used by another process.
System.Net.Mail.MailMessage msg = new System.Net.Mail.MailMessage();
SmtpClient client = new SmtpClient();
string attachmentPath="c:\test.jpg"
if(attachmentPath != "") {

What's the problem with the following:
Code:
#define K 3;
int max(int a, int b) {
return a>b? a : b;
} int main() {
cout<<max(K, K+3);
return 0;
}
Why is it not allowed, and how is it different from:
Code:
int max(int a, int b) {
return a>b? a : b;
} int main() {
cout<<max(3, 3+3);
return 0;
}
I have a socket connection already set up, my thing is what would be the best way to send a packet through sockets? My teacher wants us to convert the packet to bits first before we send it. I think he wants something like this:
Code:
struct packet{
int header
int message
int flag
}clientpacket; m
My question is how do we covert this to bits, before sending it. One of my friends said we can create a char[] array the size of the struct as a buffer. will memcpy() change the struct to bits if I copy it to the buffer?
this is how is suppose to look in bits for the header field/column.
Field : header
Field size(bits): 8
data format: Unsigned int
value example: 1
Value in bits: 0000 0001
I am confused, I think I send a structure over the socket but I did not convert it to bits before I sent it .
I want to apply program to send matrix from client and server ,and return back a processed matrix ..
How I can do it using UDP ,it was easy to use tcp for that!?
Verify my Method . I am not getting expected output ..
Code:
int Amount=500;
send(newSocket,Amount,4,0);
close(welcomeSocket);
recv(clientSocket,Amount,4,0);
// Amount= ntohl(Amount);
printf("Data received: %d",atoi(Amount[0]));
I want to write a program(s) so that the client sits and waits for a scanf to receive an int, then send to server, server then receives the int, processes it, then goes back to sit and wait for new input. to start with, where do i start! server side, or client side? and also what order do i have to go in my program before the loop to set up the socket, and listen? and then what gets looped to keep the connection open and wait for new receive?

I know how to simulate keystrokes but I have yet to figure out or find out any way of sending a string to a program. pseudo code:
int main() {
string a;
int howManyTimes;
cin >> a;

//user enters "pizza"
for(int i = 0; i < howManyTimes; i++) {
//now I want "pizza" to be sent to the program keystroke enter or whatever the correct syntax is sleep

I am writing some code to send text to a third part software. Basically each sending looks like this:
p << "set terminal eps
";
p << "set output '07.eps'
";
p << "plot '-' using ($1 == 0 ? NaN : $1) with lines linecolor 2 title 'comparison ratio',
'-' using ($1 == 0 ? NaN : $1) with lines title 'comparison ratio'
";
p.send(TOex_ar).send(TOnew_ar);
p << "set terminal wxt 7
";
p << "plot '-' using ($1 == 0 ? NaN : $1) with lines linecolor 2 title 'comparison ratio',
'-' using ($1 == 0 ? NaN : $1) with lines title 'comparison ratio'
";
p.send(TOex_ar).send(TOnew_ar);
Each time I have to change the number "07" and "7";decide to add or not the following parts: "using ($1 == 0 ? NaN : $1)", "with lines", "linecolor 2";and write the title 'comparison ratio' and the name of data to send "TOex_ar" and "TOnew_ar".Since I have to do this kind of thing 50 times in my code, and it is in the form of text, I am wondering whether in C++ we can write a template or function to simplify the program, just to input the changing parts.
I wanted to make an program which is sending messages to log in and password, but instead of message it gives me "System.Windows.Forms.TextBox, Text: AND HERE MY TEXT I WANTED.

It apears that this is AMF(Action Message Format) type packet Content-Type: application/x-amf it is in binary and this complicates things a little because I cannot send it with regular httpwebreqeuest class(Or I think so)
I used Fiddler4 with AMF plugin to check what data was passed with that packet
It apears that these numbers under content / 0 are User-id that is needed to add user to friends
I did a research with little success finding any usefull examples. I just found that there is a library for FLEX/FLASH remoting called fluorinefx and this should do the job but when I opened documentation it seems little too complex for me.

I am trying to convert decimal value 1 to 32 to hex value and insert it at 4th pos of char array and send it as hex value at the serial port .
My issue is it is converting to decimal to hex value but when it sends, it treat the converted hex value as char and sends it equivalent hex value.
For example
if decimal =1 then its hex = 1.
so , writebuffer[3] =1
But when we send whole writebuffer through send function, it treat this 1 as char and sends its hex value as 31. how to send its hex value.
unsigned int i=0;
char hex[3];
unsigned char hexunsigned[3];
unsigned int dec;
do {
unsigned char writebuffer[8] ={0x01, 0x05, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00};
[Code] ....
The send function is
void serial::send(unsigned char data[], DWORD noOfByte) {
DWORD dwBytesWrite;
WriteFile(serialHandle, data, noOfByte, &dwBytesWrite, NULL);
}
I've got something I'm trying to accomplish, but crashes my program.
I've got my server and client code.
Having the client send a message they type (char Chat[1024]) And the server receiving the chat (char recv_chat[1024]) only to send it to all connected clients again. Which the server sends the recv_chat.
The client receives it (char recv_chat[1024]). This works, and the client gets the right info. However, I'm trying to store it using a vector. I'm sure I've tried any way possible.
Client storing vector pseudo-code:
vector<char*> SaveChat;
int main () {
while (true) {
if (newClientConnected) {
[Code]....
This doesn't work, and crashes my application. I've tried changing the vector to string, const char*, basically anything I can with no avail.
I'm building a project in my free time and in the last part of it I need to fill a form of a website and then 'hit submit', but how it can be done. Btw the form is a 'POST' form so it's harder than a 'GET' one.
View 2 Replies View RelatedHow to send a keystroke or a mouse event to another running process in Ubuntu? I want to write a C program that reads data from the USB port sent by AVR Micro Controller board continuously.In response to that it checks the data received and sends a command to another process running on the computer? Example,when the program reads 101 from the USB port it sends left mouse button down to the VLC media player window that is currently running?
View 1 Replies View RelatedI am new to this area and have the requirement like:
1) A running process wants to send message based on event arrival.
2)the process checks if event is critical
3)if critical then it has to send message immediately ,else send after time t.
4) The process is continuously process the events . so once it knows the event is not critical and has to send message later it has to proceed with its normal operation.. only when time 't" comes it has to come and send message.
I have some experience in C# and choose the project of a "rapidfire script". It is a program, which shoot rapidly in a FPS by sending a "left-mouse-button-click" over and over again while the "real" left mouse-button is down.
Now, I tried multiple ways of sending the left mouse button but none of them worked the way I wanted them to. I tried SendMessage, PostMessage and mouse_event. One of them made the window unresponsive, another only pressed the mouse button while I was still moving the mouse and another didn't work at all.
I know a script which does exactly that and is coded in AutoHotKey. AHK is open-source but since I am not familiar with C++, it is very hard for me to understand what exactly is going on here:
AutoHotKey: keyboard_mouse.cpp
And here is the AutoHotkey-Script: AutoHotKey - pastebin.com
And my current code. The input delay is very irregular and strange. Sometimes the real "right mouse button click" gets ignored and I don't know why.
if (State == RapidfireState.ACTIVE) {
// Check if the left mouse button is down. If it is, send fire commands to the game
if (MouseDown()) {

I am currently trying to send a x264 nal unit using WINSOCK with a reliable multicast socket. It isn't decoding properly, and my initial thought is I am not receiving all the bytes correctly. I was hoping some fresh eyes can provide insight on errors or any improvements. I have seen some topics about this subject, and they showed sending entire structs with the socket. However, I am concerned about endianess so I am trying to stay away from that approach. I have commented out the decoding part, until I am confident that I am receiving the nal unit properly.
Server:
#include <WinSock2.h>
#include <WS2tcpip.h>
#include "wsrm.h"
#include <Windows.h>
#include <stdio.h>
#include <stdint.h>
#include <iostream>

Code: ....
string cmd = "dir c:filequeue > ";
string outputFilePath;
outputFilePath.append(getTempPath());
outputFilePath.append(" est.txt");
cmd.append(outputFilePath);
system(cmd.c_str()); // dir c:filequeue > %temp% est.txt
string content = get_file_contents(outputFilePath.c_str());
send(s, content.c_str(), content.length(), 0); I'm executing the "dir" command to get a listing of Folders/files of one Folder. Then I read the Output of the file and send it over winsock to the Server.
Now, the Problem is, I don't know how I can handle the recv properly, cause I have to set the buffer size without knowing, how much data is actually transfered. Sometimes maybe no files are in c:filequeue, sometimes a 100k.
So I tried to make recv as a Loop:
Server:
Code: ...
while (rc != SOCKET_ERROR) {
printf("
#");
gets(buf); //please no discussion about gets, I will Change this later ;)
if (strcmp(buf, "ls") == 0){
send(connectedSocket, "LIST", 4, 0);
[Code] .....
now it works, but as the recv blocks, it will never leave the Loop, even when the Transfer is finished.What should I do?
I believe I could make unblocking sockets, but that's a bit complicated. Isn't there an easier solution, with malloc'ing the buffer or a Signal when to leave the recv Loop?
ok to start, windows based program, using pelles c ide
winsock2, using "sample" codes, able to connect, BUT no clue what 1/2 of the codes do, and most of the coding is for nix based systems!
trying to understand, and implement a minimal amount of code to add to a current menu based program!
being able to open connection, wait for input from server, receive input, acknowledge the input, then "act" then return to waiting for new input.
or vice versa, server waiting on client (but then server would have to send all the current status`s to client, so that client could be in real time, prob by sending an array from server to client).
I am just wondering if it is possible to send a project to someone via email - In a simple way, almost like you would install software from the internet, maybe a setup file, or something. The compiler I use "Dev C++" creates a .cpp file and an executable. Unfortunately, I cannot send that .exe file. How would you recommend sharing a program?
