  • MATLAB: Automatic detection of relations between workspace variables through functions

    - by Peterstone
    Hi all, I´m trying to write a function what detect this relation between the variables I have got in the workspace: v1 - fft(v2) = 0 Where v1, v2 are variables of my workspace. Sometimes I need to know which variables have a certain numerical relation. If I have thirty, I don´t want to be looking for this relation in "manual way", just itroducing a sentence for each pair of different variables. I would like a function in which I introuce (or I modify this function every time I need it) the sentence (for instance what I wrote before) and the function show me the pair of variables a I am looking for. Does anyone know how to do it? Thank you so much!

  • Tracing Erlang Functions - Short forms

    - by Roberto Aloi
    As you might know, it's now possible to trace Erlang functions by using the short form: dbg:tpl(Module, Function, x). Instead of the usual: dbg:tpl(Module, Function, dbg:fun2ms(fun(_) -> exception_trace() end)). I'm actually wondering if a similar short form is available for return_trace(). Something like: dbg:tpl(Module, Function, r). Instead of: dbg:tpl(Module, Function, dbg:fun2ms(fun(_) -> return_trace() end)). The source code in the dbg module seems to suggest not: new_pattern_table() -> PT = ets:new(dbg_tab, [ordered_set, public]), ets:insert(PT, {x, term_to_binary([{'_',[],[{exception_trace}]}])}), ets:insert(PT, {exception_trace, term_to_binary(x)}), PT. But I might be wrong. Do you know of any?

  • Wrong shortcut icons on the desktop and in the programs menu

    - by Zenya
    When creating a program setup, I also put some documentation or readme files in it. However after the program is installed, I get wrong icons on the desktop and in the programs menu, as below: What I expected: I thought that for the registered file types (such as pdf, txt, doc, etc.) I don't need to set icons manually in the setup project. Am i wrong? As far as I know some other installers doesn't have such problem. Does anybody know how to fix this for Visual Studio? My environment is: Visual Studio 2005, C#, Windows XP Pro SP3

  • designing classes and objects in .net for a restaurant assignment

    - by Dell Boy
    I have received an assignment at School for creating a Restaurant site. I have to use objects and classes (OOP) for my assignment. I have the foundations of the OOP in .net, but what I don't know is how can I design this assignment to be object-oriented. I don't know how to start it. The requirement is like this: The menu has to be saved in a database and retrieved from it. The menu is devided in appetizers, Salades, Main Meal, Pastas, Wines, Beverages, Extras, Do I create classes like this: Base Class: Menu Derived classes: Appetizers, Salades, Main meal, Pastas, wines, etc. If you have a good example about how to create classes from a Menu that will be great. You don't have to rely on the example I gave above. The menu can be anything. I can deside what the menu will contain. thanks a lot. I am waiting for some help. Please

  • Custom Item in ListActivity on Android

    - by Honza Pokorny
    Hello everyone, I've spent hours reading through the SDK reference, googling and reading tutorials - but I still can't figure it out. I would like to know how to create a custom list item in the ListActivity widget on Android. Something similar to a Twitter client interface. Each list item has different types of text, possibly an icon, etc. Does anyone know of any resources that would help me understand the process of creating something like that? Any guidance would be appreciated. Thanks

  • Visual studio 'View in Browser' shortcut to specific page?

    - by WowtaH
    We are using Visual Studio 2008 and would like to know if there is a way to create a (keyboard or toolbar) shortcut for the 'View in Browser'-command, but with a specific page from a specific (loaded) project. We always start testing/debugging our app from "Somepage.aspx" from "Project-x". I would like to make a shortcut that does 'View in Browser' with this specific page/file, from this specific project. So even if I am currently working on another file in another project (from the same solution) it should still work... Anybody know if this is possible, and if so, how this can be achieved? Thanks!

  • Web programming: Apache modules: mod_python vs mod_php

    - by Olivier Pons
    Hi! I've been using for more than 12 years PHP with Apache (a.k.a mod_php) for my web development work. I've recenlty discovered python and its real power (I still don't understand why this is not always the best product that becomes the most famous). I've just discovered mod_python for Apache. I've already googled but without success things like mod_python vs mod_php. I wanted to know the differences between the two mod_php and mod_python in terms of: speed productivity maintainance (I know `python is most productive and maintainable language in the world, but is it the same for Web programming with Apache) availability of features e.g, cookies and session handling, databases, protocols, etc.

  • Handling Dialogs in WPF with MVVM

    - by Ray Booysen
    In the MVVM pattern for WPF, handling dialogs is one of the more complex operations. As your view model does not know anything about the view, dialog communication can be interesting. I can expose an ICommand that when the view invokes it, a dialog can appear. Does anyone know of a good way to handle results from dialogs? I am speaking about windows dialogs such as MessageBox. One of the ways we did this was have an event on the viewmodel that the view would subscribe to when a dialog was required. public event EventHandler<MyDeleteArgs> RequiresDeleteDialog; This is OK, but it means that the view requires code which is something I would like to stay away from.

  • Adding a MongoDB collection to Netbeans

    - by Saif Bechan
    In Netbeans I have an option to add my mysql databases to netbeans. This way I can easily browse and so small queries. Now I am working on a MongoDB project, and I want to know if it is possible to use the same functionality. I see that on the website of mongo there is a list of drivers, and I see that you can add drivers in netbeans. I do not know if the same thing, or if this can be used. I have tried google, but no luck. Anyone have an idea?

  • Building an application that includes a DB, and need recommendations

    - by Rubys
    I'm going to build a little system for personal use, and I want it to save data to a database. The language is going to be C#, and so I'd like to use this opportunity to get my head around LINQ to SQL. I have some DB experience and I know my SQL, but it was all in school using Access, which is giving me trouble, and so I'd like to use another DB, something that is small in size, easy to install, and should work with LINQ to SQL. The problem is: I don't know any except Access, and am looking for recommendations. To sum it up: I need a lightweight, easy to install, linq-to-sql supporting database for a small system on a home computer, any recommendations?

  • Manual stack backtrace on Windows mobile (SEH)

    - by caahab
    Following situation: I'm developing an windows mobile application using the sdk 6. Target machine is a nautiz x7. To improve the error reporting I want to catch the structured exceptions (SEH) and do a stack backtrace to store some information for analysis. So far I have the information where the exception was thrown (windows core.dll) and I can backtrace the return adresses thru the stack. But what I want to know is, which instruction in my code caused the exception? Does anyone know how to use the available exception and context information to get the appropriate function/instruction address? Unfortunately windows mobile 6 sdk for pocketpc does not support all the helper functions to do stackwalks or mini dumps.

  • Javascript one-liners

    - by peoro
    Often I find some really cool javascript one liners that you can copy and paste into your browser address bar in order to get some fancy effects or even useful ones. This, for example, will let you edit anything on the page. javascript:document.body.contentEditable='true'; document.designMode='on'; void 0 What is your favorite? EDIT: I know that technically all these snippets are just javascript scripts that gets evaluated by the browser as if they were defined in the page. I also know that many browsers have got extensions to let you run javascript code (also letting you store scripts somewhere, providing a good editor etc etc). However that's not so practical; I'm not a javascript developer, haven't got firebug installed, and I can't install it anywhere I go. My idea idea is that of collecting the best "mini-scripts" that whoever can just copy and paste in his browser without the need of installing extensions and stuff.

  • deploying flex on tomcat

    - by ron
    Hello, I am using Flash builder 4 (SDK3.5) to create my flex program. I want to deploy this program and load it to a tomcat server. I configure my "flex server" root folder and other parameters in the project properties. The problem is, that i don't know how to make it generic. e.g. my friend's tomcat is installed in other directory on the computer. I know that in eclipse i can run the server and tomcat from the IDE. I can't see how i do it in Flash builder plugin for eclipse 4. There is a server configuration, but there isn't adapter for tomcat. Any ideas? thanks.

  • Should I always call Page.IsValid in ASP.NET WebForms C#?

    - by mkelley33
    I know to never trust user input, since undesirable input could be compromise the application's integrity in some way, be it accidental or intentional; however, is there a case for calling Page.IsValid even when no validation controls are on the page (again, I know its bad practice to be trusting user input by omitting validation)? Does Page.IsValid perform any other kinds of validation? I looked at MSDN, and the docs seem to suggest that Page.IsValid is only effective if there are validation controls on the page, or the Page.Validate method has been called. A friend of mine suggested that I always check Page.IsValid in the button click handlers every time even if there are no validation controls or explicit Page.Validate calls. Thanks for any advice!

  • Looking for an Open Source Project in need of help

    - by hvidgaard
    Hi StackOverflow! I'm a CS student on well on my way to graduate. I have had a difficult time of finding relevant student jobs (they seems to be taken merely hours after the notice gets on the board) , so instead I'm looking for an open source project in need of help. I'm aware that I should choose one that I use, but I'm not aware of any OS-project that I use that needs help. That's why I'm asking you. I don't have any deep experience, but I here are some of my biggest projects so far: BitTorrent-ish client in Python (a subset of BitTorrent) HTTP 1.1 webserver in Java Compiler from a subset of Java to run on JRE Flash-framework project to model an iPad look and feel (not to run actual iPad programs) complete with an API for programs. Complete MySQL database for a booking system, with departure and arrival times, so you could only book valid tickets (with a Java frontend). I know, Java and languages like AS3 and C# feels natural per se, Python, and have done a fair bit of hacking around in C, but I don't feel very comfortable with it. Mostly I'm afraid to make a fuckup because I have such a high degree of control. I would like to think I'm well aware of good software design practices, but in reality what I do is ask myself "would I like to use/maintain this?", and I love to refactor my code because I see optimizations. I love algorithms and to make them run in the best possible time. I don't have any preferred domain to work in, but I wouldn't mind it to be graphics or math heavy. Ideally I'm looking for a project in C++ to learn the in's and out's of it, but I'm well aware that I don't know that language very well. I would like to have a mentor-like figure until I'm confident enough to stand on my own, not one to review all my code (I'm sure someone will to start with anyway), but to ask questions about the project and language in question. I do have a wife and two children, so don't expect me to put in 10+ hours every week. In return I can work on my own, I strive to program modular and maintainable code. Know how to read an API, use Google, StackOverflow and online resources in general. If you have any questions, shoot. I'm looking forward to your suggestions.

  • Visual Studio 2010 - Export (Project) Template menu option grayed out

    - by Jakobud
    In Visual Studio, I want to make a simple C++ project and export it out as a template, so I can use the template to start new projects to save me time. But the Export Template menu option is always grayed out. I've not once been able to click it. Anyone know why? Anyone know how to accomplish what I need (besides the obvious "make a copy of an existing project in explorer")? It seems like project templates should be a no-brainer feature for VS. This seems to be the case for Visual Studio 2005, 2010 (I probably 2008 as well I haven't checked).
