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.
int myfunc( int a, int b, char * c ) char a = "(int)myfunc()"; char b = "(int,int,char*)" call(a, b, ...) // Function name and return type, params
I want to do function what registers forward what will get callback if the time is right. Basically then i dont need to edit and add extra functions into source files. I just have to include header and use register forward function. If there is anything close to this it would be perfect!
I'm trying to implement a simple template array class, but when i came into the operator< i actually have to use a template :
my code is something like :
template<typename _Type, std::size_t _Size> class array { public :
[Code] ......
but i am having an error of shadows template param 'class _Type' is it w/ the name conflict between the array template parameter and the function template parameter ?

I have a generic template class with another template in one of its types. Now I want to specialize one of its methods for a particular (template) class, which leads to a compile error, however.
GCC ends with: :35:27: error: type/value mismatch at argument 2 in template parameter list for ‘template<class Type, template<class> class O> class Foo’ :35:27: error: expected a class template, got ‘Obj2<Type>’
What is wrong with the specialization? Can it even be achieved and how (if so)?
how I want the code to look. Only problem is it doesn't work (Line 11). I have some experience with templates but I'm not a pro.
Basically I want the "Channels<3>" to be a type that I can use to specify a Cable with similar to vector<float/int> it would be Cable<Channels<2 or 3>>.
What have I messed up with the syntax?
#include <iostream> #include <vector> using namespace std;
where 'g()' returns an object of the element type. However, the compiler is claiming, no matter how I write a call to the overload, the original template is selected and/or the overload is invalid, depending on the various ways I attempt to write said overload.
I have tried several variants on this code to no avail. Outer is in a header, along with the extern template statements, and the specializations after main are in their own cpp file. Main is in a different cpp file.
What do have to do to make this work? I cannot bring the definitions of f() into the header, and they will be different for different template parameters. Ideally, I want Test to remain a private member of Outer, though this can change if it's the only option.
And then have another template function declaration for all the attractor functions where I pass the same template value as in the first one.
As you can see, I'm calling another functions inside called attractors(_tmp). I know that one way around it could be to get rid of that function and just do all the logic inside of each if statement. Is there any way to pass the same template function parameter within a template function parameter?

I am getting error at the assertion points when i call to the class as follows:
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 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 have a project, to make a program that spams chat programs. I've been trying to figure out how to send a string to an open program such as notepad, or a chat window. 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; cin >> howManyTimes; //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 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.
I captured packet that is sended to server then that button is clicked
POST (info hided)/amfgateway.php HTTP/1.1Host: (info hided) Connection: keep-alive Content-Length: 52
[Code].....
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.
If I have a text file named, stuff at a specified path in the c : drive, how do I send the contents of this file to another computer using the Internet?
I am trying to get all these functions work together and send the value of countX and countY back into main from function2() and function3() to be used by function4() later on.. But I keep getting 0 printed out and I am not quite sure why.
Code:
#include<stdio.h> #include<stdlib.h> #include<time.h> #define maxrow 20 //defines maxrow as a constant of 20 #define maxcol 30 //defines maxcol as a constant of 30 }
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.
