  • Is there a library / api for reading the contents of a .hlp help file?

    - by boccato
    I have a help file for my program and was asked to add a description of the menus in a toolbar as the user browses them. So I thought I could just use the beginning of the menu's description of the help but just cant find how to access the contents of it. I saw WinHelp has a macro language, so I figured maybe through this, but I couldnt find any references on this around. Anybody now some pointers or examples of hot to do this?

  • a good resource or book for architecting object-oriented software

    - by Ygam
    I have looked at a couple of books and all I have looked at were just discussing the technicalities of OOP. By technicalities I mean, here's a concept, here's some code, now get working. I have yet to see a book that discusses the architectural process, what are the ways of doing this, why doing this is bad, how to actually incorporate design patterns in a real-world project, etc. Can you recommend a good resource or book? I am mainly programming with PHP but a language-agnostic book/resource would do :)

  • Set up homeserver with single IP to host multiple sites on Ubuntu [closed]

    - by Ortix92
    I am trying to set up my homeserver so it can function as a regular server one would rent. I am running Ubuntu 12.04 LTS with openpanel. I have a single static IP address. I am used to having two addresses and pointing them to NS1.domain.tld and NS2.domain.tld and setting up the propper DNS records. I would also like to mention I am somewhat new to DNS zones. Either way, how would I go about setting this up correctly (in openpanel) with just a single IP address if possible at all? I have also read about free solutions online, but I would like to keep everything secure and private so other people can't peer into my data somehow. Thanks!

  • Touchscreen on KDE and Ubuntu?

    - by The Quantum Physicist
    I just bought a Lenovo Yoga 2 Pro... I liked the activity of the touchscreen on Windows, and it makes sense as it does on my smart phone. However, I'm not a regular windows user, so I installed Kubuntu 14.04, and everything looks fine, except that the activity of the touchscreen is so silly that it's useless. Why? Because all the touchscreen does is a single mouse with left click. For example, if I touch the screen for a relatively long time, I don't get the effect of a right click. How do I configure the touchscreen properly to get the activity expected on Ubuntu and KDE? Thanks for any efforts.

  • How do machine code instructions get transferred to the CPU?

    - by user3711789
    I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?

  • SSH logins failing before success

    - by Vincent
    I am running Ubuntu 12.04 Server, updated, to run a webserver on Tomcat 7. I have about 1000 clients that are very very often using an RSYNC program to sync some file with this server. Those RSync are using SSH with a certain user to open connections on the server. The result is that my server is, as normal, full of connections by the same user. About 5 connections per 1 second every day any time. Then, when I try to open a regular SSH connection with my Putty client, the connection fails before login saying "Server unexpectedly closed network connection", about 6 times for 10 attemps, anbd for 4 attemps out of 10, it works normally and I am able to login as any user. Is there a overload of connections here? The server statistics are very calm saying less then 40% of network usage and less of 2% CPU. How can I improve this? Thank you for any help. V.

  • How many xml http requests is too much for a pc to handle?

    - by Uri
    I'm running mediawiki on an apache on a regular pc running vista (don't know the specific specs, but I'm guessing at least duo core 2 2 giga hertz processor, broadband connection (500 kb/s at least, probably 1 mega). I want to use the MediaWiki api to send a lot of requests to this server. Most of the time the requests will be sent through LAN (but sometimes through the internet). I'm talking thousands of requests every few seconds at worst case. (A lot of these requests may repeat themselves, I guess some sort of cache would help) Will the server handle this, or do I need a stronger/dedicated computer? (I'm not looking for specific yes/no, but just want to get an idea as to what configuration of computer will support how many request per second) Thanks

  • How are the concepts of process and threads implementated in Linux kernel?

    - by Shan
    Can any one explain how are the concepts of process and threads implemented in Linux kernel ? I am looking for an intuitive explanation with some C snippets ( and important data structures) that clearly distinguishes between the two. I am just looking for the key implementation ideas I should get hold off. Essentially, I want to understand them and implement something similar in an embedded target (not supporte by any OS) in C language.

  • do you call them functions, procedures or methods?

    - by lowlyintern
    consider a standard c# 'function' public void foo() { //some code } In c or c++ this is called a 'function' - even if taking no parameters and returning no value. In another language maybe it would be a 'procedure'. In object orientation speak it would be called a 'method' if a class member. What would be the correct term to use in c#?

  • How to use vim's syntax files in emacs to color the text

    - by Vijayender
    Are there any snippets to make emacs use the .vim syntax files found in /usr/share/vim/vimfiles/ for coloring text. Many applications like conky have the vim syntax files like "conkyrc.vim" for vim but not for emacs. So is there an easy way to use those files rather than rewriting a new language-mode for each of those available in vimfiles directory.

  • What is the point of C++/CLI?

    - by Earlz
    Hello, I am wondering what the uses of C++/CLI is. It seems to me that it is basically C++ running on .Net, am I wrong in this thinking? What is it good for? Why not just use C# or some other truly managed language instead?

  • Experiences using Wt C++ framework?

    - by StackedCrooked
    Has anyone actually used Wt? Did it work well? Did you experience certain limitations? Or advantages? Note: Please avoid the discussion of whether C++ is suited to be a web development language. I just want to give Wt a try because it seems like a fun thing to do.

  • Features to remove from C++

    - by Justin Ethier
    This question was inspired by What features would you like to see added to C++? (also see What features do you miss in C++?). C++ is a great general-purpose language, but perhaps too general and feature-rich: multiple inheritance, operator overloading, manual memory management, templates, smart pointers, virtual destructors, legacy frameworks (think MFC), and I could go on. Is there any one feature or aspect of C++ that you would like removed to make our lives easier as C++ developers? One feature per answer, please.

  • DNS lookup fails when forwarding to subdomain

    - by Kitaro
    In order to migrate to a new mailserver with little dns problems/downtime, I have set up a second postfix that is currently accessible on a subdomain mx record, eg. the main postfix accepts mail for [email protected] while the second postfix also accepts mail for [email protected]. I added a forwarding rule to postfix saying that postfix should forward mail destined for [email protected] to [email protected] (for regular local delivery) and to [email protected]. Local delivery still works as expected, but when trying forward the mail to the new mx, postfix appeds the domain part at the end of the forwarding address, resulting in [email protected], which of course fails and the mail bounces. Why does postfix mess with the alias name in that way and how can I turn that of?
