  • Help with Jquery function

    - by Madhur Ahuja
    Ok, Here is my problem: I have this function in a third party javascript library defined as RedirectLink(a,b,c,d,e) where a,b,c,d,e are strings. I also have a link in my webSite which is again autogenerated (And I can't change it) <a href="javascript: RedirectLink("1", "2", "3" ,"4" ,"5")" id="mylink" > What I need to do is, read this anchor's (mylink) href and I need to call RedirectLink function such as javascript: RedirectLink("1", "2", "3" + param, "4" , "5"). where param will come from query string. The first part is easy, reading the href but how to alter the third parameter ?

  • Create and copy a Windows Mobile 5.0 operating system image

    - by user20119
    We have several dozen Windows Mobile 5.0 devices (Symbol MC7095 handhelds equipped with embedded Verizon WLAN, if that matters) that all need the same software and configuration. We connect all of these devices via a USB cradle to add software to them via Microsoft ActiveSync, and then do several configuration changes directly on the handhelds themselves, in the OS. That process takes 30 minutes or more, per device. Is there any way to set up one device and take a 'disk image' of the entire OS/software, such that things could then be copied (quickly/easily) to the other devices? Is such a thing possible, with Windows Mobile devices?

  • Function chaining depending on boolean result

    - by Markive
    This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario. In my asp.net application I am running a script to generate a new project my code at the top level looks like this: Dim ok As Boolean = True ok = createFolderStructure() If ok Then ok = createMDB() If ok Then ok = createProjectConfig() If ok Then ok = updateCompanyConfig() I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example). I was just wondering how other people handle this scenario? the vb.net single line if statement is quite succinct but I'm wondering if there is a better way?

  • Create a select tag with some options grouped and others not grouped

    - by dontangg
    I'm using Rails 3. I want to create a select tag with some options grouped and others not grouped. Options would look something like this: Income Auto Fuel Maintenance Home Maintenance Mortgage In this example, Income is not a group, but Auto and Home are. I see three helper methods grouped_options_for_select and grouped_collection_select, option_groups_from_collection_for_select. Is there a way to use a helper to do this or will I have to generate the HTML myself? I imagine I could use two different helpers to create the options and just append the results of both.

  • How to create a bash function with variable parameters/arguments to grep several keywords/tags

    - by CornSmith
    I'm using the :!grep "tag1" filename | grep "tag2" filename | grep -n "tag3 or more" filename command in vim to search for my code snippets based on their tags (a simple comment at the top of a snippet) in one big file. I use snippets to remember tricky things. This is painful to write out each time. I'd like to make an alias, or function to do something like this: :!greptag tag1 tag2 ... tag39 And it should search the current doc and return the lines with all the tags on them. Vim is set to interactive shell mode so that it can parse my bashrc for aliases/functions. set shellcmdflag=-ic How can I construct a function that allows for variable arguments like this in bash?

  • Overloaded function print

    - by Olga Shirokova
    For one of the assignments I need to create an overloaded function print that prints an element or all elements of an array. I have no problem with printing the entire array: for( int i = 0; i < size; i++) cout << list [ i ] <<endl; But how do I make the same function to print only one particular element? The way I see it is to ask a user what to print, either one element or all numbers. Or am I missing something here?

  • Ubuntu Linux -- create custom burnable/bootable DVD image?

    - by ashgromnies
    I recently developed some kiosk software that runs on Ubuntu Linux, and my client needs me to set up ten more computers with the complete software package(and that number will only grow in the future). So I'm looking for a way to make this less of a pain in the neck and prevent me from shooting myself in the foot -- I had to disable some things on the installations of the operating systems like screensavers, automatic updates, etc. that would pop up and disrupt the kiosk operation. I don't feel comfortable doing that by hand across 10 computers, it seems stupid. Does anybody have recommendations for software that would let me burn an installable DVD with a complete image of the hard drive from one of the devices? I've looked at Clonezilla, G4L, and PartImage and I'm still not quite sure if any of them offer what I need. I know PartImage for sure won't work, because it doesn't support Ext4.

  • Create or override Rails Active Record macros (

    - by Jocelyn
    In a Rails app, Active Record creates created_at and updated_at columns thank to macros, (it seems to be also called "magic columns"). See Active Record Migrations I have some questions about that mecanism: Is it possible to override that to get a third column (e.g. deleted_at) ? Is it possible to create a new macro t.publishing that will create publish_up and publish_down columns, for example? And where to code that? Obviously, I know I can add those columns manually, but I wonder how to achieve it with macros. Working on Rails 4.

  • Windows Server 2008 scheduled tasks cannot create files

    - by Nick Cartwright
    We have a series of tasks which, when run interactively over the command line run fine creating temporary files and (importantly) logs and backups. When we schedule the task with Administrator privileges to run at the highest priority, however, no logs or temporary files are created! All the directories have read/write privileges as administrator. Has anyone else experienced this?? We are running Windows 2008 Server & the job is configured for 'Windows Vista or Windows Server 2008'. Any help would be much appreciated! OK - so we installed Z-Cron and it works perfectly.... Still a really really strange error from Windows 2008 Task Scheduler, but a solution is perhaps not quite so urgent now we have Z-Cron working!

  • Mediawiki create user error after migration

    - by ing0
    So I had a mediawiki installed on windows with MySQL (running on AWS RDS). I've since moved it to a debian server for various reasons, but I think I've messed up the database because of the different versions of mediawiki I have used. The windows install was v 1.20alpha (58f390e). The new debian install is v 1.15.5-2squeeze4. I've tried to update debian but it doesn't find an update, so is this the latest squeeze version? Everything seems to work ok except adding users. It gives me a database error so I ran php maintenance/update.php which ran some stuff OK but didn't make a difference. I think I've not done the correct approach to this sort of move, does anyone know of a better way of doing it? I still have the old wiki running - but not used - on windows (using the same database) so I could always try this again.

  • Certain running applications cause middle-click in firefox to function differently under windows 7

    - by Charlie
    If I have photoshop, vlc player, or even just the windows task list open, when I middle click in firefox to get it to open in new tab (by depressing both buttons on my Lenovo g550 with alps touchpad), the mouse icon changes to some variety of scroll type feature, middle click doesn't work, and if I persist then the other programs take focus, and some crash. I assume the scroll like feature must be intended as added functionality in either windows 7 or the alps touchpad driver, but no settings adjustments seem to be able to remove this, and I could see nothing regarding this in firefox. I would really like to fix this! Thanks.

  • Calling C/C++ library function from PHP

    - by Anon. BlackBerry Developer
    We have a PHP web app running on a customer's machine. For an update, we have a bit of code in C that we'd like to include as a native opaque library along with the PHP web app. How does one go about calling a C/C++ lib. function from PHP? It cannot be assumed that the PHP app, called by the web server, has any sort of permission to call an exec(), eval(), or system() type of function to execute a C wrapper driver which in turn uses the C/C++ library, so it would need to be a direct C library use from within the PHP code.
