Boost Spirit: Parse an int into a string.

Maximilien21-Feb-17 2:54

21-Feb-17 2:54

I am trying to parse an expression like this:

F( 1, 2, 3)

and extract 1, 2 and 3 as a strings.

My test grammar and program parse properly, but the output is not "nice",

In the start, limit and increment variable contain strings like "\x1", "\x2" and "\x3"

This is part of my grammar. (the pre tag does not work "good" here)

I also tried to read the numerical value as an int and use a boost::variant to hold either an int or std:wstring, but that did not work.

Any thoughts, hints or tips ?

Thanks.

Hi, I'm still a beginner in coding, I need block cipher source code for my research paper where I need to get the run time for mode of operation, I already find a lot of source code but none of it seems working, example the crypto++ . I don't even know how to set it up. if anyone could help me at least on how to run the crypto++ . and fyi im using a quad core processor laptop, windows 10 and visual studio 2015. :((  :((  :((

this is the crypto++ I downloaded

You could use Microsoft Crypto API. They provide documentation and examples: Using Cryptography (Windows)[^].

Books on learning wxWidgets and understanding terminology?

If I do some C++ programming and I get to the point where I wish to make some graphical programs, I'm kind of leaning in the direction of using wxWidgets. Was wondering though if there are some books out there that explain things.

I hate to look at code and not know what this word means or this symbol.

For example if I see that something reads:

wxFrame* window = new wxFrame(NULL, -1)

I can't stand not knowing what each part of that means.

So my question is are there any books that do a good job of explaining things like that which I will undoubtedly run into?

I do recognize some of that since I've done some Java which always uses classes so.

Hi
I have CAsyncScoket Class In CwinThread (UI)

I know all the notification are done in the Context Of the MainThread

When I do get notification from lets say a OnSend I have the Threadid in the CAsynSocket

class and Do A PostThreadMessage to the thread to do the send

However I am trying to Close the Scoket in the same thread I created it

All the while whether in the main thread or CwinThread the m_hSocket value is the same

Without seeing your code this can't be answered.

But some possible reasons are:

The socket has been closed already
The function is called from another thread
The socket has been detached
You have a statically linked MFC application, created the socket in a secondary thread, and did not call AfxSocketInit in that thread

I don't quite get this thing I've noticed

If you just got done writing some C++ code and naturally you want to save the file, you tell Windows where you want to save it and then you will see in the bottom field the Save as Type question. If you choose .cpp, and just do that alone the file will not be saved as a C++ source file.

I don't get it.

Seems to me if you tell it that you want to save it as a .cpp source file then all you should have to do is just figure out what you want to name your file and that's all.

But you actually have to give the file the .cpp extension yourself.

You can't just do this: My Program

You have to do this: My Program.cpp

Why?

That is correct, Windows cannot guess what type your file is.

Well if the drop down box says Save as .cpp file, Windows does not have to guess. It should be saved as a .cpp file. Otherwise we have a wasted box with useless info in it.

Richard MacCutchan13-Feb-17 21:49

13-Feb-17 21:49

I guess you think there is something special about a .cpp file. It is just a text file that (may) happen to contain C++ source code. But that means nothing to Windows, it is just a convenience for us humans.

The file type recognition is controlled by windows and windows by default doesn't know what a .CPP is or many other types for that matter. More distinctly it doesn't know what program to associate to the file type. That is all done via the File Type Association widget in control panel in windows. The save file dialog is a common control dialog from windows and it is it that is directing the prompt.

Usually any good installer for a C++ program makes the changes for association to the file type for you. So either you have a lazy installer for a C++ program or it made the association and you have since broken it.

Whatever the case stop complaining about it and go fix it in the File Type Association widget in the windows control panel. If you need assistance an internet search on "File type association on Windows" should give you a multitude of links to work with. It's a bit like complaining when you click on a .BMP file it doesn't open it in the right editor, yeah so go fix it.

As an extra helpful tip I can tell you that on the file type association it is useful to select plain text filter onto the .CPP file type. That allows windows searches to go inside your .CPP files on a text search. It is sometimes useful if you have a lot of code directories (like I do) to find a specific block of code if you know something unique about it. You can do a computer wide search for the text string in a .CPP file and it has saved me hours of searching.

UDP Server vs Client

Please direct me to an article that discusses the difference between a UDP Server application and the Client application.

So far I surmise that the server starts with no knowledge of where a client might be. It can either begin broadcasting data (this is my current need) or listen for a client to connect.

On the other hand, the client must know the address of the server and it either begins listening for broadcasts from the server or it sends a message to the server to accomplish something, such as to solicit some information from the server.

Thank you for your time

Google for "sockets udp" and you will find plenty. Be aware that if you use UDP then you need to implement your own protocol for checking that all messages get processed, and in the correct order.

I have done that. Here is the first page of results from my good search for “udp sockets”

Before providing the list, I do suspect that if I already knew the differences I may well find that information in these sites. As I do not, that information can be rather difficult to pick out.

https://www.cs.rutgers.edu/~pxk/417/notes/sockets/udp.html
goes right to code, does not discuss the difference
http://www.cs.dartmouth.edu/~campbell/cs60/socketprogramming.html
does not discuss why there is client and server with UDP
https://en.wikipedia.org/wiki/Network_socket
does not discuss
https://www.w3.org/TR/tcp-udp-sockets/
Section 9 begins UDP, jumps right into code with no explanation
Just for the record, this is the most thorough discussion I have found

“server” is in the article in only one place discussing a Windows bug
http://www.microhowto.info/howto/listen_for_and_receive_udp_datagrams_in_c.html
Starts off with:
Suppose that you wish to write a server that implements the …
But does not address the differences.
References RFC 867 which does not discuss the differences

Do I need to continue?
I am looking for a discussion on the differences between server and client in UDP operations. Not in the code difference but in the difference in concept between the two. Looks to me like two servers or two clients can well carry on a conversation via UDP packets.

Thank you for your time

There is no big difference, apart from the fact that the server is (usually) passive and the clients active. I'm not really sure what your real issue is, since this is not anything specific to UDP.
