• How to structure Javascript programs in complex web applications?

  - by mixedpickles

  Hi there. I have a problem, which is not easily described. I'm writing a web application that makes heavy usage of jquery and ajax calls. Now I don't have experience in designing the architecture for javascript programms, but I realize that my program has not a good structure. I think I have to many identifiers referring to the same (at least more or less) thing. Let's have an exemplary look at an arbitrary UI widget: The eventhandlers use DOM elements as parameters. The DOM element represents a widget in the browser. A lot of times I use jQuery objects (I think they are basically a wrapper around DOM elements) to do something with the widget. Sometimes they are used transiently, sometimes they are stored in a variable for later purposes. The ajax function calls use strings identifiers for these widgets. They are processed server side. Beside that I have a widget class whose instances represents a widget. It is instantiated through the new operator. Now I have somehow four different object identifiers for the same thing, which needs to be kept in sync until the page is loaded anew. This seems not to be a good thing. Any advice?

• 'For' Loop Within a 'For' Loop and Then Another?

  - by BenjaminFranklin

  This has confused me quite a bit, but it's also really interesting! I want to loop through a grid of 9 elements in an array, multiply them all by 1/9. Then, I want to find the sum of those 9 elements and replace each individual element's with the value calculated as the sum. After I've done this, I want to move on to the next nine elements. To clarify, I want all 9 elements to be changed to myVal, in the code below. So far I've got the loop within a loop bit, but I don't know how to then go back and replace each of the values with the sum of all of them combined. Here's my code:- previousx = 0; previousy= 0; for (int x = previousx; x < previousx+4; x++) { for(int y = previousy; y < previousy+4; y++) { y = y*(1/9); yVal += y; } } Any advice would, of course, be greatly appreciated.

• Interrupting a thread from inside a runnable class? (java)

  - by kyeana

  I am trying to set up a method inside a class that implements the runnable interface that will set the interrupt status of that class. The reason i want to be able to do it from inside the class is there is some other clean up stuff that i need to take care of as well, and i would like to be able to do it all by calling one method instead of calling, for example: Gui gui = new Gui() // class that implements runnable Thread guiThread = new Thread(gui, "gui thread"); guiThread.start() ... ... guiThread.interrupt(); gui.cancel(); Currently my cancel code looks like this, however it isn't correctly setting the interrupt status of this thread. public void cancel() { Thread.currentThread().interrupt(); // other clean up code here. } Any advice on if/how i could get this working? Thanks. EDIT: I when i tried to get the cancel working, i commented out the guiThread.interrupt(), so that i wasn't just setting the status the reseting the status.

• Returning a Value from a jQuery Dialog Button Instead of Running a Function

  - by kamera

  I'm working on an admin UI and I can't wrap my head around how to get a specific kind of modal behaviour. I'm using jQuery. I already have a system for modal dialogs in place, where an openModal(settings) function opens a modal. Based on the settings, it will show/hide or sometimes inject various dialogs. I also have a generic confirmation dialog and this is the one I'm not sure how to make work. The layout is simple: <div id="confirmation-dialog"> <h2>Are you sure?</h2> <button class="button.yes">Yes</button> <button class="button.no">No</button> </div> I could just hard-code each button to do what I need it to do but I would like this to be more generic. Ideally, I would like it to function like this: (I know this doesn't work) function deleteImportantThing() { if (confirmThis() == true) { // Delete the thing } else { // Do nothing, close dialog } } function confirmThis() { openModal({kind: "confirm"}); // Check which button is clicked, then return true or false } I guess I just don't know enough JavaScript to get this to work, or to even figure out where to look. Any advice? I know there are modal dialog plug-ins out there but I'd have to change how the rest of my modals work to integrate them, and I'd like to do this myself if at all possible.

• Storing data in XML or MongoDB

  - by user766473

  Here is my usecase. 1.Have some data, which I am storing now in the xml files. The data that I am storing is not persistent i.e I would be deleting the user data once the user logs out. 2.My server communicates with the client using the XML requests and responses. So initially we decided, since we are sending the XML as response, lets store it in XML so that conversion from database to XML format time is saved. 3.Client will request for XML based on some filter conditions. So will have to use XQUERY. 4.Maximum of 100 entries will be there in an XML, atleast as of now. Now I would like to hear some advice on whether I should use XML or mongodb. My Concerns : 1. How good is it to store temporary data in mongodb and delete/take backup once done with session 2. Conversion from mongodb json format to XML. 3. Handling the changes in the schema design. Cant use any other DB than mongodb. As some persistent operation or still done on mongodb. Thanks in advance.

• Managing modes in Windows application working directly with SQL Server 2008

  - by hgulyan

  Hi, I have a MS Access 97 application (but the question is general) working directly with SQL Server 2008 (without application server or anything). Numbers of users can be up to 1000. Windows Authentication is used. The question is: How to handle modes, so some users will be allowed to work in read-only mode some users won't have access to db for some time My versions: Using a table with a mode id for every group of users, that will work the same way. On Form Load application will query that table for mode id. Using trigger on the tables, that must work according to that mode. The trigger will query mode value and doesn't work if access is closed or it's in read-only mode I know it's not these are not the best solutions, that's why I'm asking for your advice. There's one more point. If the mode is changed to "access-is-closed" for a group of users, that group must not be able to query to DB starting that moment. With first solution I wrote it won't work, because user can be in application at that moment and no form load event will work. How can I do this? Is there any optimal solution? Thank you. Any help would be appreciated.

• How to learn a new programming language? And how to choose the appropriate language?

  - by Sebi

  Unfortunately my last question was closed, so I reformulated the question: I know this question was here a lot of times and can't be answered at all, but im not looking for a single name, but rather for an advice in my situation. I learned programming with Java and now I'm developing in Java for more or less 5 years (at the university) and I thinks my programming skills their are really ok/average. I have also small experience in C/C++ and C#. Now I have some spare time and I'd like to learn a new language or deepen the knowledge of Java/C/C++. But how to choose the right language to learn? I'd like to learn a language which will be usefull in the future concerning working in a software development business? I know there is no single answer, but I'm sure you could mention some languages that are more usefull than others. And what's the best way to learn such a language efficiently (bearing in mind that one has already learned some other languages)? Just doing tutorials? Or trying to implement a project? Trying to move a Java project to the new language?

• IE7 li with image and text issue - Text . Almost working.

  - by jmoore111

  I'm using an unordered list. With an image to the left and text to the right. I only noticed today that IE7 was displaying this so badly that it wasn't even acceptable. Woops for not realising sooner. I have the given the image a class and the text wrapped in a seperate div. <ul> <li><a href="domain"><img src="http://www.domain.com/img.jpg" alt="img class="footer-thumb" width="40px" height="40px" /></a> <div class="recent-post-content"> <p>day date time</p> <p><a title="Content title" href="http://www.domain.com/contentitle &raquo;</a></p> </div></li></ul> What's happeninig so far is that it is perfect in every browser except in IE7 where the images are exactly where they should be but the class "recent-post-content" is all pushed up one exactly one image ([li] height) above so the last image doesn't have any text beside it and the first image ([li]) has its "recent-post-content" above it. I guess it's something simple but after getting this far on my own I thought it best to try and get some advice to fix the last little bit. Any ideas? Thanks

• Is my approach for persistent login secure ?

  - by Jay

  I'm very much stuck with the reasonable secure approach to implement 'Remember me' feature in a login system. Here's my approach so far, Please advice me if it makes sense and is reasonably secure: Logging: User provides email and password to login (both are valid).. Get the user_id from DB Table Users by comparing provided email Generate 2 random numbers hashed strings: key1, key2 and store in cookies. In DB Table COOKIES, store key1, key2 along with user_id. To Check login: If key1 and key2 both cookies exist, validate both keys in DB Table COOKIES (if a row with key1, and key2 exists, user is logged). if cookie is valid, regenrate key2 and update it in cookie and also database. Why re-genrating key: Because if someone steals cookie and login with that cookie, it will be working only until the real user login. When the real user will login, the stolen cookie will become invalid. Right? Why do I need 2 keys: Because if i store user_id and single key in cookie and database, and the user want to remember the password on another browser, or computer, then the new key will be updated in database, so the user's cookie in earlier browser/PC will become invalid. User wont be able to remember password on more than one place. Thanks for your opinions.

• Infrastructure for high transactional system (language & hosting suggestion help)

  - by RPS

  Some of our friends (University students) are trying to develop a twitter type application, I want to plan for at least 1000 transactions per second (I know it's wishful thinking) for initial launch. This involves several people connecting and getting updates and posting (text + images) to site. In the back end db will server the data and also calculates rankings of what to push to user based on complex algorithm on the fly real-time. Our group is familiar with Java and Tomcat/MySQL. We can also easily learn/code in PHP/MySQL. What is the best suited platform for our purpose ? Though Java seem to be easy to implement for us I am afraid that hosting will be a bit difficult. I could find cloud based php hosting services (like rackspace cloudsites) at reasonable cost. Amazon EC2 is a bit over our heads to manage on day-to-day. Also any recommendation on hosting ? (PHP or Java) We don't have millions in seed money but about $20K to start with. Any advice on above or any thing in general approach is much appreciated.

• Associate two sets of values

  - by PJW

  I have the following code - public static int GetViewLevel(string viewLevelDesc) { try { switch (viewLevelDesc) { case "All": return 0; case "Office": return 10; case "Manager": return 50; default: throw new Exception("Invalid View Level Description"); } } catch (Exception eX) { throw new Exception("Action: GetViewLevel()" + Environment.NewLine + eX.Message); } } public static string GetViewLevelDescription(int viewLevel) { try { switch (viewLevel) { case 0: return "All"; case 10: return "Office"; case 50: return "Manager"; default: throw new Exception("Invalid View Level Description"); } } catch (Exception eX) { throw new Exception("Action: GetViewLevelDescription()" + Environment.NewLine + eX.Message); } } The two static Methods enable me to either get an int ViewLevel from a string ViewLevelDesc or vice versa. I'm sure the way I have done this is far more cumbersome than it needs to be, and I'm looking for some advice how to achieve the same objective but more concisely. The list of int / string pairs will increase significantly. The ones in the above code are just the first three I intend to use.

• Php header('Location") error

  - by Umeed

  I'm having some difficulty with my php coding. I have 3 files, add.php, lib.php, and view.php I created a simple form, and when the user clicks submit, it should direct them to the view.php where it will display the database. Now I'm having a couple issues I can't seem to resolve. when the user clicks submit and the fields are blank or there is an error no entry should be made into the view page (or database)...however when I click submit a blank entry is made into the database. ALSO if i click "enter product" from the top menu bar anytime I click it, it causes a blank entry into the database. I can't figure out why that's happening. My next issue is with the header('Location') and my browser says: "Warning: Cannot modify header information - headers already sent by (output started at lib.php:13) in add.php on line 16" However if I click submit on my form it goes away. Here is the code for the pages: http://ideone.com/Vvz8x I truly apologize if the code is really messy. Any help / advice / solution is greatly appreciated thank you. And yes this was an assignment---it was due last week but since I couldn't finish it, it's not worth any marks anymore.

• Proper way to reassign pointers in c++

  - by user272689

  I want to make sure i have these basic ideas correct before moving on (I am coming from a Java/Python background). I have been searching the net, but haven't found a concrete answer to this question yet. When you reassign a pointer to a new object, do you have to call delete on the old object first to avoid a memory leak? My intuition is telling me yes, but i want a concrete answer before moving on. For example, let say you had a class that stored a pointer to a string class MyClass { private: std::string *str; public: MyClass (const std::string &_str) { str=new std::string(_str); } void ChangeString(const std::string &_str) { // I am wondering if this is correct? delete str; str = new std::string(_str) /* * or could you simply do it like: * str = _str; */ } .... In the ChangeString method, which would be correct? I think i am getting hung up on if you dont use the new keyword for the second way, it will still compile and run like you expected. Does this just overwrite the data that this pointer points to? Or does it do something else? Any advice would be greatly appricated :D

• Manage the scrolling of just one element in a ScrollView

  - by morgan1189

  So, I have a ScrollView which has cards on it. ScrollView must be paging enabled. The goal is that the user must be able to scroll it, even if it has only one card. Since i am having the frame of ScrollView of exactly the same width and height as a picture of a card, i decided to increase the width of a ScrollView.contentSize and add one point to it. It turns out to be working fine, but it glitches a bit - when i drag the card to the left, and then grab it again it moves to right a little bit (i guess, for the value of that one point). If i increase the contentSize, the shift increases too (for example, if the content size is increased by ten, the shift value is ten points too). It really irritates me a lot and I want to get rid of it. Any advice on how to do that? Help is much appreciated. UPD: I tried to manually re-center the card in the scrollViewDidEndDecelerating but that didn't help. My guess for now is that the problem can be solved by setting the content offset to the right value (because now it's (0,0)), but I can't figure out how to do it.

• Reading a text file, and performing actions based on strings read

  - by user1691766

  Let me start off by saying that I really am quite new to C. So basically I have a text file (contains around 30 assembly instructions, separated by new lines), and I am successfully reading them into my program. From here I need to perform certain actions based off each instruction. I would assume the best way to do this would be via a switch-case statement. However I am encountering a lot of problems due to me trying to compare strings that are 33 characters long. Can anyone please offer me advice on what I am doing wrong, or offer an alternative? Thanks in advance. Here is what I have so far: char instruction[29][ 33 ]; int i,run; i = 0; run = 1; FILE *instPtr; /* LOADING INSTRUCTIONS FROM FILE INTO "instruction" ARRAY*/ if ( ( instPtr = fopen("MIPSinstructions.txt", "r") ) == NULL ) { printf("File could not be opened\n"); } // end if else { fscanf( instPtr, "%s", instruction[0]); printf("%s\n", instruction[0]); while (!feof( instPtr ) ){ i++; fscanf( instPtr, "%s", instruction[i]); printf("%s\n", instruction[i]); } fclose( instPtr ); i = 0; // Reset the counter } //end else return 0; }

• Async run for javascript by using listeners

  - by CharlieShi

  I have two functions, the names are Function3, Function4, Function3 will send request to server side to get jsondata by using ajax, which, however, will take about 3 seconds to complete. Function4 is a common function which will wait for Function3's result and then action. My code puts below: function ajaxRequest(container) { $.ajax({ url: "Home/GetResult", type: "post", success: function (data) { container.append(data.message); } }); } var eventable = { on: function (event, cb) { $(this).on(event, cb); }, trigger: function (event) { $(this).trigger(event); } } var Function3 = { run: function () { var self = this; setTimeout(function () { ajaxRequest($(".container1")); self.trigger('done'); }, 500); } } var Function4 = { run: function () { var self = this; setTimeout(function () { $(".container1").append("Function4 complete"); self.trigger('done'); },500); } } $.extend(Function3, eventable); $.extend(Function4, eventable); Function3.on('done', function (event) { Function4.run(); }); Function4.on('done', function () { $(".container1").append("All done"); }); Function3.run(); but now the problem is, when I start the code , it always show me the result as : first will appear "Function4 complete", then "All done" follows, 3 seconds later, "Function3 complete" will appear. That's out of my expection because my expection is "Function3 complete" comes first, "Function4 complete" comes second and "All done" is expected as the last one. Anyone can help me on this? thx in advice. EDIT: I have included all the functions above now. Also, you can check the js script in JSFIDDER: http://jsfiddle.net/sporto/FYBjc/light/ I have replaced the function in JSFIDDER from a common array push action to ajax request.

• Looping through array values using JQuery and show them on separate lines

  - by user3192948

  I'm building a simple shopping cart where visitors can select a few items they want, click on the "Next" button, and see the confirmation list of things they just selected. I would like to have the confirmation list shown on each line for each item selected. HTML selection <div id="c_b"> <input type="checkbox" value="razor brand new razor that everyone loves, price at $.99" checked> <input type="checkbox" value="soap used soap for a nice public shower, good for your homies, price at $.99" checked> <input type="checkbox" value="manpacks ultimate choice, all in 1, price at $99"> </div> <button type='button' id='confirm'>Next</button> HTML confirmation list <div id='confirmation_list' style='display:none;'> <h2>You have selected item 1</h2> <h2>Your have selected item 2 </h2> </div> JS $(function(){ $('#confirm').click(function(){ var val = []; $(':checkbox:checked').each(function(i){ val[i] = $(this).val(); }); }); }); I ultimately want to replace the words 'Your have selected item 2' in h2s with the values selected from each check box. With the code above I'm able to collect the values of each checkbox into an array val, but having difficulty looping through and displaying them. Any advice would be appreciated.

• Can a pc with a 1.2 ghz dual core run VS 2013? [on hold]

  - by moo2

  Edit: This question is about a tool used for programming, Microsoft Visual Studio 2013. I already read the minimum requirements for VS 2013 before I posted or I wouldn't have asked the question. I searched on the web for an answer for a few hours before posting. Why should I go out and spend $400 on a laptop if I can spend less than $100 and use it to learn how to program? In the context of the question it is clear I was not asking for advice on what laptop to buy and it was also clear I was not asking for someone to walk me through the system requirements of VS 2013. This is a vast community and I was wondering if someone in this vast community would have experience in dealing with my question. In other words has anyone ever tried anything like it? If I had an old computer sitting around I would have tested it. At the moment all I have is a friend's Chromebook I'm borrowing. End Edit. I know the requirements for Microsoft Visual Studio 2013 state 1.6 ghz processor. I'm looking at getting a laptop for school and I found one that is old but cheap and would work for college. The Dell D430 I'm looking at getting has a 1.2ghz Core 2 Duo CPU, 80GB HD, 2GB RAM, and Windows 7 Home Premium. It's refurbished. I can get it for less than most phone's cost and from a Microsoft Authorized Refurbisher. I know it's not a skyrim rig but it's lightweight and can handle being a college laptop and doing word processing. Would Visual Studio 2013 run at all? If it is slower I'm not concerned. I just want to know if it would work and compile my assignments and run them? I'd be using this laptop for doing assignments and learning programming languages not for coding the next social media sensation.

• Best (in your opinion) GIT workflow for case when releases are done on demand (in most cases 1-2 tickets at once)

  - by Robert

  I'm rather a Git newbie and I'm looking for your advice. In the company I work for we have a "workflow" where we have a single Git repo for our project with 2 branches: master and prod. All devs work on the master branch. If a ticket is done (from the dev perspective), we push to the repo. If all tests are passed, we make a release. The issue is that in most cases, the request from business guys sounds like: "please release ticket A or A && B". In most cases, I end up doing something like git checkout prod git cherry-pick --no-commit commit_hash git commit -m "blah blah to prod" -a As you can see this is not a perfect solution, and I'm under a huge impression this is a perfect way to nowhere especially when change A depends on changes B and C. Do you have any suggestions how to handle releases on demand if more devs works on the same branch and the flow looks like I described above? All suggestions are welcome. I cannot change business processes and it will have to stay as it is - unfortunately.

• Windows Azure Directory Sync Generic Failure

• Want to use something like Citrix XenClient, Free Alternative?

  - by Chris

  I'm looking to go into IT, general office server management, and it looks like XenClient would be a awesome tool to use. If I get it right, you would store a central image of the OS you want to deploy (in an iso file) on the main server. Then use XenClient to pull that image down to the client, and it will then boot the OS inside of the virtual machine. Does it download the image of the OS and store it locally (like cloning the VM onto the client?) I'd love to find a free (possibly open source?) alternative to this, I keep on hearing about KVM in Linux and PXE booting a minimalistic OS to use remote KVMs.... Would that be what I'm looking for? Ideally, I'd like a system.. - That allows me to manage one central image for multiple clients (virtualized hardware) - Easily push a new VM onto the client for easy updating. - Be able to keep files in sync (but that might be a samba / active directory's job) Would those things be possible with some kind of free alternative? Some guidance would be greatly appreciated.

• Unpacking a ZTE ZXV10 H108L router firmware

  - by v3ng3ful

  I binwalked a firmware of a ZTE ZXV10 H108L, and got some encouraging results of uImage uboot, and LZMA compression, as well as a Squashfs 3.0 LZMA compressed filesystem. 256 0x100 uImage header, header size: 64 bytes, header CRC: 0xE70BCBB9, created: Thu Nov 10 04:54:54 2011, image size: 804172 bytes, Data Address: 0x80002000, Entry Point: 0x80266000, data CRC: 0x6EFE90F1, OS: Linux, CPU: MIPS, image type: OS Kernel Image, compression type: lzma, image name: MIPS Linux-2.6.20 320 0x140 LZMA compressed data, properties: 0x5D, dictionary size: 8388608 bytes, uncompressed size: 2637958 bytes 851968 0xD0000 Squashfs filesystem, big endian, lzma signature, version 3.0, size: 2543403 bytes, 632 inodes, blocksize: 65536 bytes, created: Thu Nov 10 04:56:12 2011 Now what I did is, to test several portions of the file (320byte-end, 851968byte-end, and many more) using dd, and trying with certain tools to uncompress/unpack the filesystem of the firmware. After some digging I found out the best tool to do this is the firmware_mod_kit, that understands a squashfs-lzma v3 filesystem. Although I ended up really frustrated as unsquashfs-lzma v3 reported a cold "zlib::uncompress failed, unknown error -3". Do you have any ideas? Could it be that, the firmware is corrupted on purpose to discourage attempts like this? Router file Thanks

• How to make my SanDisk Cruzer Blade 4GB disk back to normal?

  - by Jack

  Currently, my SanDisk Cruzer Blade 4GB have become a 64MB Firebird RAW flash drive (thumb drive). I don't know why it become like this but when I plug it into a PC, it suddenly transform itself to become a 64MB flash drive. (From 4 GB to 64 MB, that is a huge change!) I read the following articles: http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/Cruzer-Blade-will-not-format/td-p/214932 http://forums.whirlpool.net.au/archive/1691847 http://forum.hddguru.com/sandiskfirebird-64mb-t23539.html and notice that their solutions does not work at all. Some of their solution is as follows: Using the HP USB Disk Storage Format Tool (http://files.extremeoverclocking.com/file.php?f=1970), which did not work for me as it could not format. Using the h2testw to see if it is genuine, which did not work for me because it is a RAW partition. Return to the vendor, which I doubt since the product only have 1 year warranty and it has expired. I also notice that the flash drive is very fragile as after a few use, the flash drive have become something like the following: (The upper cover of the USB connector was broken or torn) So, wondering if someone have any good solution to fix it back so that at least I can retrieve my data on the fragile thumb drive.

• Cannot reactivate RAID-5 volume: The size of the plex member is invalid

  We had a 3-drive Windows Server 2008 R2 RAID-5 fail (operating in redundancy mode): WDC 1 TB WDC 1 TB WDC 1 TB We removed the failed hard drive, and put a WDC 1 TB drive (that we had standing by) into the machine. When launched, Disk Manager, asked permission to "initialize" the disk as either: Master Boot Record (MBR) Guid Partition Table (GPT) We initialized the disk as GPT, converted it to dynamic, and tried to use the Repair Volume command - except it was greyed out. (which is a terrifying thing on a failed production server hosting 3 virtual servers) i tried from the diskpart command line tool. First we look for our RAID-5 volume that is in Failed Rd mode: DISKPART> list volume Volume ### Ltr Label Fs Type Size Status Info ---------- --- ----------- ----- ---------- ------- --------- -------- Volume 0 E VMs (Raid5) NTFS RAID-5 1863 GB Failed Rd Volume 1 D DVD-ROM 0 B No Media Volume 2 System Rese NTFS Partition 100 MB Healthy System Volume 3 C NTFS Partition 1862 GB Healthy Boot There, Volume 0. Make that our active context: DISKPART> select volume 0 Volume 0 is the selected volume. Now we need to find the disk we will be repairing the volume with: DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 931 GB 0 B * Disk 1 Online 931 GB 931 GB * Disk 2 Online 1863 GB 0 B Disk 3 Online 931 GB 0 B * Disk M0 Missing 0 B 0 B * The disk with 931 GB free, Disk 1. Now we just need to repair the volume: DISKPART> repair disk=1 Virtual Disk Service error: The size of the plex member is invalid.

• How do I install and use the cli53 tools on Windows?

  - by pavlos

  I'm trying to find the simplest way to import a large number of BIND zone files in to Route 53. I've had a quick look at the AWS CLI and AWS Tools for Windows PowerShell but they don't seem to include a zone file import option like the AWS Route53 GUI does. The cli53 utility on the other hand does, but is written in Python and appears to have a series of pre-requisites to get going which I'm having troubles working out for Windows. I can find plenty of examples of setting it up under Linux but only one reference to a PowerShell example here, but it doesn't explain how to install cli53 in the first place. The other option I'm exploring is to use the BIND to Amazon Route 53 Conversion Tool perl script to first convert the zone files to the Route53 CreateHostedZoneRequest XML format and then use the AWS New-R53HostedZone PowerShell cmdlet to import the zones. After the zones have been imported I'll be looking at running a script to validate what has been created in Route53 matches with the existing nameserver prior to updating each domains nameserver records - I was planning on whipping something up using the new PS4.0 Resolve-DnsName cmdlet, but let me know if you have any better suggestions. Any assistance would be greatly appreciated - thanks. (By the way, I had more reference links in my post but ServerFault won't allow me to post more than 2 links being a new member; and for this same reason I also can't comment on Vasili's example in the other linked thread)
