• How to get last 12 digits from a string in MySQL?

  - by Nick Gorbikoff

  Hello. How would I get last 12 digits of a string using mysql? Let's say I have a varchar field with a tracking number, that may be anywhere from 5 to 20 varchars long. But I only need to select last 12 digits or less if there are less. so in a field = 12345678123456789012 I would only need to get what's in brackets field = 12345678[123456789012] I saw a few examples using mid, etc, but they dont' produce the desired result or I can't find an example that makes sense :-( Thank you.

• JavaScript Drag and Drop Grid With Elements of Different Sizes.

  - by Paul67

  I need to be able to drag and drop boxes of differing dimensions on the same grid. JQuery UI seems to offer 80% of what I'm after particularly the sortable grid the have on their demo page. The only problem is that this grid only works with boxes of identical dimensions. My requirement is to be able to have the same functionality but with boxes that are sized as multiples of the base unit. For example - let's say the standard box size is 300x300px I would also like the opportunity to show on the same grid a 300x600px and a 600x600px box. There's no requirement to display boxes that are not multiples of the dimensions of the smallest box size.

• How to determine the date that Office 2003 was installed

  - by GalleySlave

  Is there any guaranteed way of determining the date that Office 2003 (and .Net Framework v2.0) were installed on a client computer? I am trying to nail down a problem which I think is due to the order that the .Net Framework and Office 2003 were installed in, so I need a way I can get a client to have a look at their machine (preferably the file system) and let me know. It may require admin privileges (or Registry etc) which wouldn't be a problem but not the preferred solution. It appears that the folders under Program Files\Microsoft Office\Office11 have a number with the same date which at first sight appear to be an installation date / time. Likewise in Windows\Microsoft.Net\Framework\v2.0.50727 there are two with the same date, but this seems less certain. I could use WMI with a winmgmts:object and SELECT * FROM Win32_Product, but was wondering if there was a 'telephone' way to do it!

• Wait window in a windows application

  - by Vinodtiru

  I basically need to show a wait window to the user. For this i have put two seperate window forms in the application. the first form is the main form with a button. The second one is a empty one with just a label text. On click of the button in Form1 i do the below Form2 f = new Form2(); f.Show(); Thread.Sleep(2000); f.Close(); My idea here is to show the wait window to the user for 2 second. But when i do this the Form 2 is not completely loaded because of which the label in it is blank. Please let me know your inputs on this.

• How to hide/show div using jQuery without altering dimensions?

  - by Byron S

  I have a div that is holding a google chart: <div id="chart_div" style="width: 600px; height: 300px;"></div> It has one CSS property: display: none. On the click of a button, I would like to have the chart be displayed using jQuery hide() and show(). It's working, however, the chart's dimensions are set to something different than I have specified and refuse to change to what I have specified. Here is my jquery code: $(document).ready(function(){ var chart = $('#chart_div'); $('#submit').click(function(){ chart.show('slow'); }); }); Let me know if theres any more code you would like to see. By the way, the chart div is not being contained in anything else so that isn't the problem.

• Htaccess/robots.txt to allow search bots to explore main domain but not directory on other domain

  - by gX

  Ok, I understand the Title didn't make any sense so here I've tried to explain it in detail. I'm using a hosting that gives me space for my domain and lets me "add on" other domains on it. So lets say I have a domain A, and I add on a domain B. Basically my hosting gives me a public_html where I can put stuff that shows when someone visits website A. But, when I add the domain B, it lets me put the content of B, INSIDE of that public_html so that website B.com can also be visited by going to A.com/siteB... Thats all good, except that Google has started indexing B.com as well as A.com/siteB, I'm ok with it indexing B.com, but I somehow want to prevent it from indexing A.com/siteB so that when people search for B, it doesn't end up showing A.com/siteB. Any ideas? Let me know if the question is still unclear.

• What technologies to use for a particle system with enormous calculation demand?

  - by Amir Rezaei

  I have a particle system with X particles. Each particle tests for collision with other particles. This gives X*X = X^2 collision tests per frame. For 60f/s, this corresponds to 60*X^2 collision detection per second. What is the best technological approach for these intensive calculations? Should I use F#, C, C++ or C#, or something else? The following are constraints The code is written in C# with the latest XNA Multi-threaded may be considered No special algorithm that tests the collision with the nearest neighbors or that reduces the problem The last constraint may be strange, so let me explain. Regardless constraint 3, given a problem with enormous computational requirement what would be the best approach to solve the problem. An algorithm reduces the problem; still the same algorithm may behave different depending on technology. Consider pros and cons of CLR vs native C.

• Store data in Ruby on Rails without Database

  - by snowmaninthesun

  I have a few data values that I need to store on my rails app and wanted to know if there are any alternatives to creating a database table just to do this simple task. Background: I'm writing some analytics and dashboard tools for my ruby on rails app and i'm hoping to speed up the dashboard by caching results that will never change. Right now I pull all users for the last 30 days, and re arange them so I can see the number of new users per day. It works great but takes quite a long time, in reality I should only need to calculate the most recent day and just store the rest of the array somewhere else. Where is the best way to store this array? Creating a database table seems a bit overkill, and i'm not sure that global variables are the correct answer. Is there a best practice for persisting data like this? If anyone has done anything like this before let me know what you did and how it turned out.

• iPhone SDK: How do I programatically change the background image of a UIButton added to a NIB?

  - by user304583

  I've seen several questions/answers related to entirely creating a button in code, but not one which would let me know how to change the button image in code, when I originally added the button to my NIB in Interface Builder. I know how to change the background in Interface Builder.. but I want to change it in code, so I can change it automagically. Any help really appreciated! Perhaps the answer is so obvious nobody needs to ask.. if so please forgive the dweeb that I am and help! :-)

• Using the "IN" clause with a comma delimited string from the output of a replace() function in Oracle SQL

  - by Thomas

  Hi All, I have an comma delimited string which I want to use in an "IN" clause of the statement. eg: 100,101,102 Since In and "IN" clause I have to quote the individial strings, I use a replace function: eg: select ''''||replace('100,101,102',',',''', ''')||'''' from dual; The above query works, however, when I try to use the output of the above as an input to the "IN" clause, it returns no data. I am restricted by only SQL statements, so I cannot use PL/SQL code. Kindly help. eg: select * from employee where employee_number in ( select ''''||replace('100,101,102',',',''', ''')||'''' from dual); The above does not work. Please let me know what I am missing.

• "Dereference" var in C#

  - by chris12892

  I have some code in C# that uses a structure as such: ArrayList addrs = new ArrayList(); byte[] addr = new byte[8]; while (oneWire.Search_GetNextDevice(addr)) { addrs.Add(addr); } In this example, every element in the ArrayList is the same as the last device that was found because it would appear as though addr is passed out by reference and I am simply copying that reference into the ArrayList. Is there any way to "Dereference" addr to only extract it's value? It's also possible my assessment of the situation is incorrect, if that appears to be the case, please let me know Thanks!

• How to see "anti if" movement and its gaol?

  - by Vijay Shanker

  I have a developer for last 3 years, have been using if-else or if-else if statements a lot in my programing habit. And today, I found This link. One obvious sample i put here public void doSomthing(String target, String object){ //validate requests if(target != null && target.trim().length() < 1){ //invalid request; } //further logic } Now, I have seen this sort of check all over the places, libraries. So, I wanted to have a discussion about the worthiness of such a movement. Please let me know your views.

• How to format an email address line (with name) with PHP?

  - by nbr

  I'm trying to generate email messages. The recipient's email address and name are specified by a user. What is the correct way to do this with PHP: $to_header = "To: $name <$email>" # incorrect! I already use a decent method for validating the email addressess (let's not go to that now...), but how do I properly encode $name with eg. QP when needed? For example, if the recipient is called "Foo Bär", I should produce (eg.) something like: To: =?utf-8?Q?Foo_B=C3=A4r?= <[email protected]>

• git-svn clone checkouts wrong repo?

  - by hyperboreean

  So I am trying to switch to git, by using git-svn. I am having a svn repo called myrepo from which I want to clone just the project called myproject. The thing is that by running the following command: git svn clone path-to-repo/myrepo/myproject --stdlayout --prefix=svn myproject the whole repo myrepo is cloned rather than just myproject. I tried using -T, -t, -b as well to let git know about the layout of the project, but without any success. I always get the following output: Using higher level of URL: path-to-repo/myrepo/myproject => path-to-repo/myrepo and tries to clone that one. Am I doing something wrong? It might be that the svn repo layout could be broken or git incompatible ?

• e-commerce clothing site in .NET from the scratch or site copy ? suggestions please

  - by pointlesspolitics

  Hi all, I am thinking to create an e-commerce site for a clothing business. I have bit of a development knowledge in c# .net, html, css and other web technologies. Could you please advise on these questions ? Is it a good idea to create a site from the scratch ? I have a running example of such a site, however it is bit old. So can I start with old site and change the html and code behind ? Some people argue that it is better to use MVC for ecommerce site. Any good reasons ? BTW I don't know MVC, but can learn if I have to use it. It is decided to use .NET but if you have any ideas of better technologies, please let me know. Any ideas and issues related to payment system also welcome. Any answer will be appreciated. Thanks Rgds,

• Debug.writeline locks

  - by Carra

  My program frequently stops with a deadlock. When I do a break-all and look at the threads I see that three threads are stuck in our logging function: public class Logging { public static void WriteClientLog(LogLevel logLevel, string message) { #if DEBUG System.Diagnostics.Debug.WriteLine(String.Format("{0} {1}", DateTime.Now.ToString("HH:mm:ss"), message)); //LOCK #endif //...Log4net logging } } If I let the program continue the threads are still stuck on that line. I can't see where this can lock. The debug class, string class & datetime class seem to be thread safe. The error goes away when I remove the "#if DEBUG System... #endif" code but I'm curious why this behavior happens. Thread one: public void CleanCache() { Logging.WriteClientLog(LogLevel.Debug, "Start clean cache.");//Stuck } Thread two: private void AliveThread() { Logging.WriteClientLog(LogLevel.Debug, "Check connection");//Stuck }

• Inline Zend Navigation links in view content saved to db

  - by takeshin

  I'm storing the page content in the database (both as markup and HTML code) and displaying this content in the view (let's say it's CMS or forum post). The this data have also some links to internal pages existing in sitemap (Zend_Navigation object). It's easy to insert the link in page body just by using <a> tag. But the contents of this inline links does not change when I update the sorce XML for Zend Navigation (url's, attributes, ACL permissions). How do you handle this case? Special markup for the link, converting the link using url view helper? Iterate Zend_Navigation object extracting specific link (one by one)?

• Simple OOP-related question.

  - by M4design

  This question came to my mind quite a few times. Let my explain my question through an example. Say I've got two classes: 1- Grid. 2- Cell. Now the location of the cell 'should' be stored in the grid class, not in the cell class itself. Say that the cell wanted to get its location through a method in the grid. How can it do that? Keep in mind that the cell was created/initialised by the Grid class. What good OO approach to solve this problem? Thank you
