  • How can I rewrite this (cleanly) without gotos?

    - by Jared P
    How can I do this cleanly without gotos? loop: if(condition1){ something(); } else if (condition2) { somethingDifferent(); } else { mostOfTheWork(); goto loop; } I'd prefer not to use breaks as well. Furthermore, it is expected to loop several (adv 40) times before doing something else, so the mostOfTheWork part would most likely be as high up as possible, even if just for readability. Thanks in advance.

  • How can two instances of an application communicate in Java?

    - by shubhkarman
    Hello, I am developing a new Java Desktop app. Something like a media player. I want to load most of the resources in the background when the computer starts up. But the users can turn this option off form within the app or using some other utility. So, what I want to do is if a ban instance of the app is already running and the user starts the app again then I can communicate with the already running instance so that it can launch a new window?

  • Algorithms after load-balancer?

    - by Vimvq1987
    I need to study about load-balancers, such as Network Load Balancing, Linux Virtual Server, HAProxy,...There're somethings under-the-hood I need to know: What algorithms/technologies are used in these load-balancers? Which is the most popular? most effective? I expect that these algorithms/technologies will not be too complicated. Are there some resources written about them? Thank you very much for your help.

  • SQL Reporting Services 2005 - Date field based on a user entered date?

    - by Pierce
    Hi, I have a report in report services 2005 that has two date fields. The problem is that if users run this for a large section of time it uses too much resources on our server. It is possible to only allow the end user to enter the start date and then the end date be auto populated/derived from this field (for example they enter the 1st of a month and this automatically change the end date to the last of a month.)

  • More RAM vs. more servers [closed]

    - by user357972
    I was recently asked "Do you know when to decide between going for more RAM or more servers?" (in the context of scaling data mining applications). I had no idea, so what are some ways to decide? I have very little knowledge of architecture and scaling (my understanding of computer memory and what a server does is limited to the high-level basics), so tips on learning more about these things in general are also very welcome.

  • CSS: is there any way to have the same relative positioning even if the previous element have differ

    - by Patrick
    hi, I have a sequence of couples of elements. (.div1, .div2) I'm using position:relative attribute on .div2 to move it a bit on top and right with respect to div1. However .div1 elements have different content and heights, so the relative positioning of .div2 is not consistent (they sometimes are too high, sometimes too low). .div2 { position:relative; left:200px; top:-300; } thanks

  • Need to write a daemon in linux, not sure what to use C++ or C

    - by Bluescrod
    Hello everyone, I have a little problem picking the right language to write my daemon, I am confused between C and C++, I want to use C++ because it is more expanded than C, but I want to use C because it is the starting point of everything in linux, I want to go for C++ as I have many resources about it, so, does it make any difference if I pick C++ instead of C? and what I will have good if I learn C more? I feel like if I go into C++ I will cover C within C++... Regards

  • Should I implement IDisposable here?

    - by dotnetdev
    My method which calls SQL Server returns a datareader but because of what I need to do (return the datareader to the calling method which is in page code-behind), I can't close the connection in the class of the method which calls sql server, so I have no finally or using blocks. Is the correct way of disposing resources to make the class implement IDisposable? Or from the caller, explicitly dispose the unmanged resource (class-level fields)? Thanks

  • Mobile opera have background sound support?

    - by Mark
    I make browser/html/js games. One of my biggest pains in the arse is the lack of background sound support in mobile safari. This lack of support makes high value games pretty much impossible. Does anyone know if opera mini supports html5 audio, or any mobile browser for that matter. If not, what are some alternatives methods.

  • PHP Detect Pages Genre/Category

    - by Alexwhin
    Hey, I was wondering if their was any sort of way to detect a pages genre/category. Possibly their is a way to find keywords or something? Unfortunately I don't have any idea so far, so I don't have any code to show you. But if anybody has any ideas at all, let me know. Thanks! EDIT @Nican Perhaps their is a way to set, let's say 10 category's (Entertainment, Funny, Tech). Then creating keywords for these category's (Funny = Laughter, Funny, Joke etc). Then searching through a webpage (maybe using a cUrl) for these keywords and assigning it to the right category. Hope that makes sense.

  • phonegap crash on "resume"

    - by fancy
    My phonegap application works great but there is a glitch when it is sent to the background or "paused". When focused is returned to the app a high percentage of the time the interface is frozen and then the application crashes a few seconds later. When relaunched it is working fine again. Could anyone provide some information as to what could be causing this and where I should start trying to debug it? Thanks very much.

  • WP7 Button inside ListBox only "clicks" every other press

    - by Zik
    I have a button defined inside of a DataTemplate for my list box. <phone:PhoneApplicationPage.Resources> <DataTemplate x:Key="ListTemplate"> <Grid Margin="12,12,24,12"> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto" /> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <Button Grid.Column="0" Name="EnableDisableButton" Click="EnableDisableButton_Click" BorderBrush="Transparent"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Image Grid.Row="0" Source="\Images\img.dark.png" Width="48" Height="48" Visibility="{StaticResource PhoneDarkThemeVisibility}" /> <Image Grid.Row="0" Source="\Images\img.light.png" Width="48" Height="48" Visibility="{StaticResource PhoneLightThemeVisibility}" /> <Rectangle Grid.Row="1" Width="48" Height="8" Fill="{Binding CurrentColor}" RadiusX="4" RadiusY="4" /> </Grid> </Button> <Grid Grid.Column="1"> <... more stuff here ...> </Grid> </Grid> </DataTemplate> </phone:PhoneApplicationPage.Resources> What I'm seeing is that the first time I press the button, the Click event fires. The second time I press it, it does not fire. Third press, fires. Fourth press, does not fire. Etc. Originally I had it bound to a command but that was behaving the same way. (I put a Debug.WriteLine() in the event handler so I know when it fires.) Any ideas? It's really odd that the click event only fires every other time.

  • Lots of users still using 1.5?

    - by user246114
    Hi, I'm looking at market stats here for sdk distribution: http://developer.android.com/resources/dashboard/platform-versions.html saying that 31% of marketplace users are still running 1.5. Is it true that an OS update went out for G1 and myTouch users? I'm wondering why so many people are still running 1.5 if so? Just curious because I'd like to use th setView() method introduced in 1.6 for TabSpec, but not if so many people are still using 1.5, I might have to roll my own control, Thanks
