  • Set global hotkey with Windows modifier

    - by jay
    I want to set up a global hotkey* in VB6 that listens to the keyboard shortcut Win + O. I have found heaps of messy examples, but nothing which involves the Windows key. What's the ideal way to setup hotkeys and how does one include the Windows key as a modifier? * I'm after a global shortcut. That means I don't have to have the application in focus for it to work.

  • Function allocation

    - by novice_coder
    Where are functions stored in a C++ program? For example int abc() { //where am I stored? } I know that we can take the address of a function, that means functions are stored somewhere in memory. But I have already read at many places that no memory allocation for functions takes place. I am confused. My question may seem vague to many of you but I can't help.

    An interviewer argued me "Genrics are not completely Genrics", He provided the example (Parameters int k,int d are not generic) public static void PrintThis<T>(T a, T b, T c, int k,int d) { } He asked me if i prove still it is generics , i will be allowed to take up the next round. I did not know what he is expecting from me,and what he really means by showing such example. Guide me how to smartly face such a strange interview ?. Thanks in advance.

  • What was the most refreshingly honest non-technical comment you saw in the code?

    - by DVK
    OK, so we all saw the lists of "funny" or "bad" comments. However, today, when maintaining an old stored proc, I stumbled upon a comment which I couldn't classify other than "refreshingly brutally honest", left by a previous maintainer around a really freakish (both performance and readability-wise) page-long query: -- Feel free to optimize this if you can understand what it means So, in the first (and hopefully only) poll type question in my history of Stack Overflow, I'd like to hear some other "refreshingly brutally honest" code comments you encountered or written.

  • How to disable customization for the TabBar?

    - by mana
    Hey, within my App it should be forbidden to edit (customize) the TabBar. This means there should be no edit button and no other possibility to change the order of the items. (this is not my decision, the boss wants it that way :) ) I can't find a property to do this - so is this possible after all? cheers

  • Dropdownlist width in IE

    - by NimsDotNet
    In IE, the dropdown-list takes the same width as the dropbox (i hope i am making sense) whereas in Firefox the dropdown-list's width varies according to the content. This basically means that i have to make sure that the dropbox has to be wide enough to display the longest selection possible. this makes my page look very ugly :( Is there any workaround for this problem? How can i uses CSS to set different widths for dropbox and the dropdownlist?

  • waiting for 2 different events in a single thread

    - by João Portela
    component A (in C++) - is blocked waiting for alarm signals (not relevant) and IO signals (1 udp socket). has one handler for each of these. component B (java) - has to receive the same information the component A udp socket receives. periodicaly gives instructions that should be sent through component A udp socket. How to join both components? it is strongly desirable that: the changes to attach component B to component A are minimal (its not my code and it is not very pleasent to mess with). the time taken by the new operations (usually communicating with component B) interfere very little with the usual processing time of component A - this means that if the operations are going to take a "some" time I would rather use a thread or something to do them. note: since component A receives udp packets more frequently that it has component B instructions to forward, if necessary, it can only forward the instructions (when available) from the IO handler. my initial ideia was to develop a component C (in C++) that would sit inside the component A code (is this called an adapter?) that when instanciated starts the java process and makes the necessary connections (that not so little overhead in the initialization is not a problem). It would have 2 stacks, one for the data to give component B (lets call it Bstack) and for the data to give component A (lets call it Astack). It would sit on its thread (lets call it new-thread) waiting for data to be available in Bstack to send it over udp, and listen on the udp socket to put data on the Astack. This means that the changes to component A are only: when it receives a new UDP packet put it on the Bstack, and if there is something on the Astack sent it over its UDP socket (I decided for this because this socket would only be used in the main thread). One of the problems is that I don't know how to wait for both of these events at the same time using only one thread. so my questions are: Do I really need to use the main thread to send the data over component A socket or can I do it from the new-thread? (I think the answer is no, but I'm not sure about race conditions on sockets) how to I wait for both events? boost::condition_variable or something similar seems the solution in the case of the stack and boost::asio::io_service io_service.run() seems like the thing to use for the socket. Is there any other alternative solution for this problem that I'm not aware of? Thanks for reading this long text but I really wanted you to understand the problem.

  • What is the correct terminology to describe a visual display that is about the size of a living room

    - by JW
    I'm thinking that, as flat screens get bigger and cheaper it won't be too long before 'digital wallpaper'-like screens become popular in people's living rooms with a host of applications that could take advantage of this particular screen size/resolution. Is there a proper name for this size of screen? 'Wall Screen' - is too ambiguous 'Massive Screen' - is probably best reserved for something you'd put on the side of a sky scraper 'Small Screen' - nabbed by the mobiles 'Large Screen' - kind of means desktop I'm thinking of the kind of screen used in 'Minority Report'.
