  • VirtuaWin shows Visual Studio 2010 in all Desktops

    - by w0lf
    I'm using VirtuaWin in Windows 7 to have virtual desktop functionality and I think this program is awesome. There's one small issue, though: on the computer at work, when moving to another desktop it hides all windows in the current desktop, except any windows of Visual Studio 2010. This means that VS 2010 shows up in all desktops, while for all other windows, VirtuaWin applies the correct behavior. The strange thing is that this issue happens on one computer only; on the others I have it works OK. I have checked the Window Rules section and nothing seems strange in there. Is anyone else experiencing this kind of problem? Any ideas on how to solve it?

  • Increase process memory cap.

    - by Janis Veinbergs
    Doing copy/paste in Visual Studio 2010 RTM on Windows 7, 3GB ram machine, I was unable to copy text because of an error: Task Manager shows that devenv.exe is using a little more than 500MB. However I still have almost 1GB of free RAM available. Is that somekind of memory cap? If so, is there a way to increase it? It may be a bug, but maybe there is a workaround?

  • Visual Studio 2008 crashes whenever I try to add a file to TFS

    - by Herms
    Wondering if anyone else has seen this or knows of a way to fix it. I have Visual Studio 2008 Pro with Team Explorer 2008 installed. Starting a couple of weeks ago any time I try to add a file to TFS (using the "Add Items to Folder" button in the Source Control Explorer window) VS crashes. I briefly see an "unhandled exception" dialog appear, but VS quits right after the dialog opens. I was able to see the exception at one point, and it looked like an index out of bounds exception trying to access some UI component list at -1 (can't remember the specifics, and it closes before I can bring it up now). I've tried uninstalling and reinstalling VS a couple of times already, along with resetting all of my settings. Neither helped.

  • Restarted computer, now wireless and Visual Studio is broken

    - by Earlz
    I installed the new update for TortoiseSVN which requires a restart. Upon restarting a lot of things broke. I'm currently running a virus scan, but what would cause this? Among the things that no longer work is Visual Studio. It now says "Invalid License Data. A reinstall is required" and my wireless internet does not work. When I go to connect to my network it will say "Can not connect" and then when I diagnose the problem it says "The connection to accesspoint-name was cancelled" (and yes, canceled is misspelt like that) What could have caused this? My computer did not install any updates or anything like that upon restarting and it was running fine before I restarted it.

  • Windows Phone 7 Emulator is very long to load

    - by Frederick Marcoux
    I have the Windows Phone 7.1 SDK on my computer with Visual Studio 2010 Ultimate. I have developped an application but when I want to start it in emulator, it takes about 2 hours to load it, and it's just the O/S! The application isn't started! Is there a way to view the Task Managerof Windows Phone to know why it doesn't load? Specs: Intel Core 2 Duo 3.0Ghz VT-x 2GB of DDR2 RAM (800Mhz) Windows 7 Professionnal SP1 64-bit

  • How do I trouble shoot a program which regularlly falls into a not responding state?

    - by Dave
    Lately I've been using Visual Studio 2008 and about once a day, sometimes more it will lock up. What advanced techniques can I use to determine what is causing the problem? I believe that it's one of the plug-ins I'm using *cough*Resharper*cough* but I'd like to be sure. I've been losing work and I'd like to file a bug report somewhere but I'm not seeing anything in any of my event logs which looks suspect to me. Working on a Windows XP box.

  • vi visual mode doesn't work

    - by BobMarley
    I'm running vim (7.0.237) after sshing to a remote CentOS box, and it just won't enter visual mode. When I press 'v', it just beeps and does nothing. I'm running Ubuntu with GNOME Terminal, and the local copy of vi works fine, so I don't see how this could be a problem with the terminal. I have the same .vimrc file on the local and remote machines, and the only settings are: set nocompatible; set tabstop=4. I'm at a total loss here, any ideas?

  • StyleCop XML Documentation Header - Using 3 /// instead of 2 //

    - by Adam Jenkin
    I am using XML documentation headers on my c# files to pass the StyleCop rule SA1633. Currently, I have to use the 2 slash commenting rule to allow StyleCop to recognize the header. for example: // <copyright file="abc.ascx.cs" company="MyCompany.com"> // MyCompany.com. All rights reserved. // </copyright> // <author>Me</author> This works fine for StyleCop, however I would like to use the 3 slash commenting rule to enable visual studio to understand the comments as XML and provide the XML functionality (highlighting, auto indenting etc) /// <copyright file="abc.ascx.cs" company="MyCompany.com"> /// MyCompany.com. All rights reserved. /// </copyright> /// <author>Me</author> The problem is that when using 3 slashes, StyleCop no longer see's the header and throws the SA1633 warning. Is there anyway to configure stylecop to understand the header is contained in XML using 3 slashes? Thanks, Adam

  • WPF DatePicker IsEnabled property not changing appearance

    - by Jonathan
    I think I have found an issue with the DatePicker in the toolkit, perhaps some of you gurus can check it out. The issue is when setting the IsEnabled property of the DatePicker. If set in XAML, it stays grey even if you set the IsEnabled to true at run time. The same goes for the other way around should it start off being enabled. The button just changes the IsEnabled property of the date picker, you will see that when it becomes enabled, the style remains grayed out. <Window x:Class="WpfApplication3.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:tk="http://schemas.microsoft.com/wpf/2008/toolkit" Title="Window1" Height="300" Width="300"> <StackPanel> <tk:DatePicker x:Name="txtDate" IsEnabled="False"></tk:DatePicker> <Button Height="25" Click="Button_Click"></Button> </StackPanel> </Window> private void Button_Click(object sender, RoutedEventArgs e) { txtDate.IsEnabled = !txtDate.IsEnabled; }

  • Nested dereferencing arrows in Perl: to omit or not to omit?

    - by DVK
    In Perl, when you have a nested data structure, it is permissible to omit de-referencing arrows to 2d and more level of nesting. In other words, the following two syntaxes are identical: my $hash_ref = { 1 => [ 11, 12, 13 ], 3 => [31, 32] }; my $elem1 = $hash_ref->{1}->[1]; my $elem2 = $hash_ref->{1}[1]; # exactly the same as above Now, my question is, is there a good reason to choose one style over the other? It seems to be a popular bone of stylistic contention (Just on SO, I accidentally bumped into this and this in the space of 5 minutes). So far, none of the usual suspects says anything definitive: perldoc merely says "you are free to omit the pointer dereferencing arrow". Conway's "Perl Best Practices" says "whenever possible, dereference with arrows", but it appears to only apply to the context of dereferencing the main reference, not optional arrows on 2d level of nested data structures. "MAstering Perl for Bioinfirmatics" author James Tisdall doesn't give very solid preference either: "The sharp-witted reader may have noticed that we seem to be omitting arrow operators between array subscripts. (After all, these are anonymous arrays of anonymous arrays of anonymous arrays, etc., so shouldn't they be written [$array-[$i]-[$j]-[$k]?) Perl allows this; only the arrow operator between the variable name and the first array subscript is required. It make things easier on the eyes and helps avoid carpal tunnel syndrome. On the other hand, you may prefer to keep the dereferencing arrows in place, to make it clear you are dealing with references. Your choice." Personally, i'm on the side of "always put arrows in, since itg's more readable and obvious tiy're dealing with a reference".

  • Quick question - how to comment if-else structure?

    - by serg555
    Lets say you have: if(condition) { i = 1; } else { i = 2; } and you need to put comments explaining if and else blocks. What's the most readable way of doing it so someone can easily pick them up at first glance? I usually do it like this: //check for condition if(condition) { i = 1; } else { //condition isn't met i = 2; } which I find not good enough as comments are located at different levels, so at quick glance you would just pick up if comment and else comment would look like it belongs to some inner structure. Putting them like this: if(condition) { //check for condition i = 1; } else { //condition isn't met i = 2; } doesn't look good to me either as it would seem like the whole structure is not commented (condition might be big and take multiple lines). Something like that: //check for condition if(condition) { i = 1; //condition isn't met } else { i = 2; } would be probably the best style from comments point of view but confusing as a code structure. How do you comment such blocks?

  • general learning methodology

    - by momo
    just wanted to hear on the different general learning paths people embark on when learning a new language/framework. the one i currently use, which is how i learned bash and am currently learning python, is: instant hacking tutorial (very short tutorial introducing the basic syntax, variable declaration, loops, data types, etc. and how they are generally used) in depth tutorial with good programming style and slightly topic-specific (e.g. Mark Pilgrim's Dive into Python), important topics for me personally are regex methods, file IO, and ways the different data types are utilized best (i wrote a very primitive bayesian spam filter using python's dictionaries to keep track of word occurrences) spaced-repition of syntax or short recipes (i use anki, with questions like 'create dictionary with filename and filesize metadata, human-readable' or simpler ones like 'match 0 - 3 occurences of the letter M in a string', or 'return/create an iterator from two sequences') the use of spaced-repitition has been invaluable, and i credit it with the ease that i can recall/create python algorithms. however, i've recently started looking into django, and i've found that spaced-repitition, at least in my case, doesn't work very well for learning a framework, it works best with short code recipes (either that or i should start looking into more basic django framework tutorials). the problem i'm encountering is that since framework programming is not only algorithms, but actually learning the API, which can be quite complex since you have to learn all the methods, modules, the places where they are stored, and the sequence of which things have to be done. for ex. in django to start a project that deals with polls (from the django tutorial), one has to create the project, edit the settings.py file, create the polls app, edit the models.py file (which requires knowing the classes that are present in the module models), edit the urls.py file, etc. i found that my spaced-repition method didn't work very well for this type of learning, so i wanted to ask you guys what method(s) you use for learning the different frameworks/APIs.

  • What are Code Smells? What is the best way to correct them?

    - by Rob Cooper
    OK, so I know what a code smell is, and the Wikipedia Article is pretty clear in its definition: In computer programming, code smell is any symptom in the source code of a computer program that indicates something may be wrong. It generally indicates that the code should be refactored or the overall design should be reexamined. The term appears to have been coined by Kent Beck on WardsWiki. Usage of the term increased after it was featured in Refactoring. Improving the Design of Existing Code. I know it also provides a list of common code smells. But I thought it would be great if we could get clear list of not only what code smells there are, but also how to correct them. Some Rules Now, this is going to be a little subjective in that there are differences to languages, programming style etc. So lets lay down some ground rules: ** ONE SMELL PER ANSWER PLEASE! & ADVISE ON HOW TO CORRECT! ** See this answer for a good display of what this thread should be! DO NOT downmod if a smell doesn't apply to your language or development methodology We are all different. DO NOT just quickly smash in as many as you can think of Think about the smells you want to list and get a good idea down on how to work around. DO downmod answers that just look rushed For example "dupe code - remove dupe code". Let's makes it useful (e.g. Duplicate Code - Refactor into separate methods or even classes, use these links for help on these common.. etc. etc.). DO upmod answers that you would add yourself If you wish to expand, then answer with your thoughts linking to the original answer (if it's detailed) or comment if its a minor point. DO format your answers! Help others to be able to read it, use code snippets, headings and markup to make key points stand out!

  • CKEditor doesn't apply inline styles to links

    - by jomanlk
    I'm using ckeditor version 3 as a text editor to create markup to be sent through email. This means that I have to have all the styles inline and anything that needs to be styled will definitely need the style applied. I'm currently using addStylesSet to generate custom styles that can be applied to elements. The problem I have is that although this works on most elements, styles don't seem to be applied to <a> <ol> <ul> and <li> I really need to be able to apply inline styles to these elements as well. I've been looking at the examples on the ckeditor site, but even they just seem to be wrapping a <span> around the link. Is there anyway I can apply inline styles to <a> tags or failing that, can I just give ckeditor a bunch of classes that can be applied to any tag (Like TinyMCE does with it's link to an external css file)? so that I can at least do a textreplace on them to get the styles inline? I haven't pasted any code here because it's exactly the same as what's been done on the ckeditor site.

  • Strange issue with fixed form border styles in Vista

    - by Nazgulled
    My previous post about this issue didn't got too many answers and it was kinda specific and hard to understand. I think I've managed to understand the problem better and I now believe it to be a Vista issue... The problem lies on all types of fixed border styles like FixedDialog, Fixed3D, FixedSingle and FixedToolWindow. It does not happen on the sizable ones. This problem, like I said, it also happens only on Vista. Let's say you have a form with any of the fixed border styles and set the starting location to 0,0. What you want here is for the form to be snapped to the top left corner of the screen. This works just fine if the form border style is one of the sizable options, if it's fixed, well, the form will be a little bit outside of the screen working area both to the left and top. What's more strange about this is that the form location does not change, it sill is 0,0, but a few pixels of the form are still drawn outside of the working screen area. I tested this on XP and it didn't happen, the problem is Vista specific. On XP, the only difference was the border size that change a bit between any of the styles. But the form was always perfectly snapped to position 0,0. If possible, without finding how many pixels are being drawn outside of the working area and then add that to the form location, is there a possible way to fix or workaround this?

  • Javascript storing properties and functions in variables

    - by richard
    Hello, I'm having trouble with my programming style and I hope to get some feedback here. I recently bought Javascript: The Good Parts and while I find this a big help, I'm still having trouble designing this application. Especially when it comes to writing function and methods. Example: I have a function that let's the user switches games in my app. This function updates game-specific information in the current view. var games = { active: Titanium.App.Properties.getString('active_game'), gameswitcher_positions: { 'Game 1': 0, 'Game 2': 1, 'Game 3': 2, 'Game 4': 3, 'Game 5': 4 }, change: function(game) { if (active_game !== game) { gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage.replace('_selected', ''); gameswitcher.children[this.gameswitcher_positions[game]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[game]].backgroundImage.replace('.png', '_selected.png'); events.update(game); this.active = game; } }, init: function() { gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage = gameswitcher.children[this.gameswitcher_positions[this.active]].backgroundImage.replace('.png', '_selected.png'); events.update(this.active); } }; gameswitcher is a container view which contains buttons to switch games. I am not satisfied with this approach but I cannot think of a better one. Should I place the gameswitcher_positions outside of the variable in a seperate variable instead of as a property? And what about the active game? Please give me feedback, what am I doing wrong?

  • Nice way to break a reply up into pieces in ruby

    - by ChaosR
    Hello, I'm writing an IRCd. For this topic it doesn't really matter if you know much about IRC. Its a simple code style problem. Quick overview of the problem: No message may be longer than 512 characters If the message is more, it must be broken into pieces The NAMES reply sends all the nicknames of users on a channel, and quickly grows beyond 512 characters. I currently concocted this marvelous piece of code, it works perfectly. However, its just not "ruby-like". This piece of code is more what you expect in some piece of C code. # 11 is the number of all fixed characters combined in the reply pre_length = 11 + servername.length + mynick.length + channel.name.length list = [""] i = 0 channel.nicks.each do |nick, client| list[i+=1] = "" if list[i].length + nick.length + pre_length > 500 list[i] << "#{channel.mode_char(client)}#{client.nick} " end list.each { |l| send_numeric(RPL_NAMREPLY, channel.name, l.strip) } send_numeric(RPL_ENDOFNAMES, channel.name) So my question is, any ideas to do this more nicely? PS. code has been slightly modified to make it easier to understand out-of-context

  • Modify columns in a data frame in R more cleanly - maybe using with() or apply()?

    - by Mittenchops
    I understand the answer in R to repetitive things is usually "apply()" rather than loop. Is there a better R-design pattern for a nasty bit of code I create frequently? So, pulling tabular data from HTML, I usually need to change the data type, and end up running something like this, to convert the first column to date format (from decimal), and columns 2-4 from character strings with comma thousand separators like "2,400,000" to numeric "2400000." X[,1] <- decYY2YY(as.numeric(X[,1])) X[,2] <- as.numeric(gsub(",", "", X[,2])) X[,3] <- as.numeric(gsub(",", "", X[,3])) X[,4] <- as.numeric(gsub(",", "", X[,4])) I don't like that I have X[,number] repeated on both the left and ride sides here, or that I have basically the same statement repeated for 2-4. Is there a very R-style way of making X[,2] less repetitive but still loop-free? Something that sort of says "apply this to columns 2,3,4---a function that reassigns the current column to a modified version in place?" I don't want to create a whole, repeatable cleaning function, really, just a quick anonymous function that does this with less repetition.

  • Help- CSS styles for text links also affecting image links

    - by blabus
    I've been working on this one for about an hour now, and I'm about ready to pull my hair out. What seems like it should be a simple one or two lines of CSS apparently isn't. I have a Posterous blog with a custom theme I designed for a client, viewable here: http://phar-ma.com/ I obviously use CSS to style the text links in the posts. My problem is, the same styles are also being applied to images that have a larger version to view, since Posterous automatically turns them into links to the larger versions (the smaller images aren't turned into links). So basically I need to figure out how the return the styling of the link images to the same as the non-link images. Right now they have weird spacing and borders around them (because of the styles for the text links) and those change when you hover over them. They're also not centered correctly. I've tried just about every piece of CSS code I know, and I've had absolutely no luck. I also searched on Google and found this: http://perishablepress.com/press/2008/10/14/css-remove-link-underlines-borders-linked-images/ but still no luck with that either. So, if anyone has any ideas, I'd appreciate it. Thanks!

  • [jQuery UI - Accordion] Styling active header?

    - by RC
    Hi, Simple issue: I am using Accordion without any UI themes (just barebones, using my own CSS). So far, so good, except that I cannot figure out how to set an "active" style for the currently selected header. The jQuery code: $("#menu").accordion({ event:"mouseover",header:"a.top" }); The HTML code: <a href="#" class="top">XXX1</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> <a href="#" class="top">XXX2</a> <div class="sub"> <a href="#">Subheading 1</a> <a href="#">Subheading 2</a> <a href="#">Subheading 3</a> </div> This works great, except that I cannot find a way to define the styles for the active header without using ThemeRoller. Manually setting the following styles in my CSS has no effect: .ui-state-active .ui-widget-content .ui-state-active .ui-state-active a .ui-state-active a:link .ui-state-active a:visited Assistance, please?

  • C++11 decltype requires instantiated object

    - by snipes83
    I was experimenting a little with the C++11 standard and came up with this problem: In C++11 you can use auto and decltype to automatically get return type for a function as, for example the begin() and end() functions below: #include <vector> template <typename T> class Container { private: std::vector<T> v; public: auto begin() -> decltype(v.begin()) { return v.begin(); }; auto end() -> decltype(v.end()) { return v.end(); }; }; My problem here is that I have to declare the private vector<T> v before the public declarations which is against my coding style. I would like to declare all my private members after my public members. You have to declare the vector before the function declaration because the expression in decltype is a call to vector member function begin() and requires an instance of the object. Is there a way around this?
