• Exploring search options for PHP

  - by Joshua

  I have innoDB table using numerous foreign keys, but we just want to look up some basic info out of it. I've done some research but still lost. 1) How can I tell if my host has Sphinx installed already? I don't see it as an option for table storage method (i.e. innodb, myisam). 2) Zend_Search_Lucene, responsive enough for AJAX functionality of millions of records? 3) Mirror my innoDB with a myisam? Make every innodb transaction end with a write to the myisam, then use 1:1 lookups? How would I do this automagically? This should make MyISAM ACID-compliant and free(er) from corruption no? 4) PostgreSQL fulltext queries don't even look like SQL to me wtf, I don't have time to learn a new SQL syntax I need noob options 5) ???????????????????? This is high volume site on a decently-equipped VPS Thanks very much for any ideas.

• How to get original url after HttpContext.RewritePath() has been called.

  - by jessegavin

  I am working on a web app which makes use of a 3rd party HttpModule that performs url rewriting. I want to know if there's any way to determine the original url later on in Application_BeginRequest event. For example... Original url: http://domain.com/products/cool-hat.aspx Re-written url (from 3rd party httpmodule): http://domain.com/products.aspx?productId=123 In the past I have written HttpModules that store the original url in HttpContext.Items but, this is a 3rd party app and I have no way of doing that. Any ideas would be appreciated.

• Stop Rails from unloading a module in development mode

  - by Gareth

  I have a module in my Rails app that lives in /lib module MyModule mattr_accessor :the_variable class << self def setup yield this end end end From my environments/#{RAILS_ENV}.rb file I can then set an environment-specific value for the_variable: MyModule.setup do |my_module_config| my_module_config.the_variable = 42 end This is lovely, and it seems to work (almost) fine. The problem is that in development mode, Rails via ActiveSupport::Dependencies unloads a load of modules, and reloads them in time for the new request. This is usually a great behaviour because it means you don't need to restart your localhost server when you make a code change. However, this also clears out my initialised the_variable variable, and when the next request comes in the initialiser (obviously) isn't run again. The net effect is that subsequent requests end up having MyModule.the_variable set to nil rather than the 42 that I'm looking for. I'm trying to work out how to stop Rails unloading my module at the end of the request, or alternatively find another way to cleanly provide environment specific configuration for my modules. Any ideas? :-/

• Sending url params and POST body to a MVC 2 Controller

  - by Luiggi

  Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

• Looking for examples of good IDEs to analyze for Form/Report design

  - by Paul Sasik

  I am working on a basic form/report designer. Some of the features i'm looking to implement are: Single or multiple selection of objects Alignment of objects (when several are selected) Same-sizing of objects (when several are selected) Moving/dragging of selected object(s) Selected object resizing in eight directions (using object grips) For features and look-and-feel I've analyzed and used a mixture of ideas from: MS Visual Studio 200x (most useful so far) Visio Crystal Reports My question is: Have I overlooked some other IDEs that provide these kinds of features that are better and user-friendlier examples of what to do than others i've looked at? (They don't have to be Microsoft products. That's just what i have ready access to.)

• What is faster: multiple `send`s or using buffering?

  - by dauerbaustelle

  I'm playing around with sockets in C/Python and I wonder what is the most efficient way to send headers from a Python dictionary to the client socket. My ideas: use a send call for every header. Pros: No memory allocation needed. Cons: many send calls -- probably error prone; error management should be rather complicated use a buffer. Pros: one send call, error checking a lot easier. Cons: Need a buffer :-) malloc/realloc should be rather slow and using a (too) big buffer to avoid realloc calls wastes memory. Any tips for me? Thanks :-)

  - by schooner

  We have a .NET 1.1 application that we keep on a netowork share. We install the .NET Framerwork to the local PCs and also set the full trust via the following: %windir%\Microsoft.NET\Framework\v1.1.4322\caspol -pp off -cg LocalIntranet_Zone FullTrust This has worked fine on all PCs to date however now we have a few new PCs with Win7 and the process no longer is working. The app will run fine from a local drive in Win7 but running the networked copy results in a general exception error. Any ideas on how to get this to work under Win7?

• iphone screen - type of view to use

  - by Fiona

  Hi There everyone... looking for some advice on what type of view can be used to build a screen with the following elements: 2 labels followed by 2 buttons. Then a small table view with 3 rows. Should a UIView be used or a UITableView? I've attempted using a UITableView - however I couldn't add the labels or buttons. So I've now built the view using a UIView. I added the labels and buttons and then a UITableView from the library. However I have no idea how to populate the rows in the table? Any ideas? Regards, Fiona

• How can I loop over a query for a specific number of times that may be greater than the result?

  - by JS

  I need to loop over a query exactly 12 times to complete rows in a form but rarely will the query return 12 rows. The cfquery endRow attribute doesn't force the loop to keep going if the result is < 12. If it did that would be ideal to use something like cfloop query="myQuery" endRow="12"... The 2 options that I have now are to skip the loop and write out all 12 rows but that results in a lot of duplicate code (there are 20 columns), or do a query of queries for each row which seems like a lot of wasted processing. Thanks for any ideas.

• PHP Variable Encryption

  - by NCoder

  I have the following code that creates an encryption in PHP: $password = "helloworld"; $passwordupper = strtoupper($password); $passwordencode = mb_convert_encoding($passwordupper, 'UTF-16LE'); $passwordsha1 = hash("SHA1", $passwordencode); $passwordbase64 = base64_encode($passwordsha1); The instructions I have from the system I'm trying to connect to states: The encoding process for passwords is: first convert to uppercase, then Unicode it in little-endian UTF 16, then SHA1 it then base64 encode it. I think I'm doing something wrong in my code. Any ideas?! Thanks! NCoder

• Dash surrounding text

  - by Brandon Hansen

  Given the above dynamically generated text (meaning that I can't just use an image), I am trying to recreate the design using just html and css selectors. I would like to just use a single h4 with the containing text, but am open to other solutions. I would prefer to not use absolute positioning, but again, if that is the only way, then so be it. I have tried surrounding with span tags, but those are inline elements that don't have an inherent width. The h4 will be nested within a div, though not always of the same class or id. Any ideas or resources to get me started?

• How do I create a WPF Dropdown panel

  - by Mitch

  I'd like to create a dropdown panel in WPF the acts like a ComboBox/Expander hybrid. I'm currently using an Expander but it pushes the the controls underneath it down when it expands. I simply want it to act like a ComboBox and overlay it's dropdown. I've looked at using Popups but they don't move with the underlying window if it's moved. So, I've concluded that the closest control to my needs is a ComboBox with allows me to put a Grid or StackPanel into its dropdown area. Any ideas how to achieve this?

• parsing/matching string occurrence in C

  - by David

  I have the following string: const char *str = "\"This is just some random text\" 130 28194 \"Some other string\" \"String 3\"" I would like to get the the integer 28194 of course the integer varies, so I can't do strstr("20194"). So I was wondering what would be a good way to get that part of the string? I was thinking to use #include <regex.h> which I already have a procedure to match regexp's but not sure how the regexp in C will look like using the POSIX style notation. [:alpha:]+[:digit:] and if performance will be an issue. Or will it be better using strchr,strstr? Any ideas will be appreciate it

• Problem processing large data using Applet-Servlet communication

  - by Marquinio

  Hi everyone. I have an Applet that makes a request to a Servlet. On the servlet it's using the PrintWriter to write the response back to Applet: out.println("Field1|Field2|Field3|Field4|Field5......|Field10"); There are about 15000 records, so the out.println() gets executed about 15000 times. Problem is that when the Applet gets the response from Servlet it takes about 15 minutes to process the records. I placed System.out.println's and processing is paused at around 5000, then after 15 minutes it continues processing and then its done. Has anyone faced a similar problem? The servlet takes about 2 seconds to execute. So seems that the browser/Applet is too slow to process the records. Any ideas appreciated. Thanks.

• How can I generate a random human-readable colour from a seed? C#

  - by SLC

  Got a logfile, and it has all kinds of text in it. Currently it is just displayed as one colour, and each entry says something like: Log from section 1: Some text here Log from section 125: Some text here Log from section 17: Some text here Log from section 1: Some text here Log from section 125: Some text here Log from section 1: Some text here Log from section 17: Some text here Now the logfile is displayed in real time, and it would be nice to make the rows with the same section number the same colour. However there could be potentially quite a large range of numbers. What I want to do is create a method that will take a number, and randomly generate a unique colour. The colour must be readable against a black background though, so #000000 is no good, nor is #101010 or anything too dark to read. Ideally two similar numbers will not produce the same colour because in the above examples, the numbers 1 and 17 might be too similar, and some numbers might be in the 10,000 range. Any ideas on this?

• DBCC CHECKDB WITH DATA_PURITY gives out of range error

  - by Mark Allison

  Hi there, I have restore a SQL Server 2000 database onto SQL Server 2005 and then run DBCC CHECKDB WITH DATA_PURITY and I get this error: Msg 2570, Level 16, State 3, Line 2 Page (1:19558), slot 13 in object ID 181575685, index ID 1, partition ID 293374720802816, alloc unit ID 11899744092160 (type "In-row data"). Column "NumberOfShares" value is out of range for data type "numeric". Update column to a legal value. The column NumberOfShares is a numeric (19,6) data type. If I run the following select max (NumberOfShares) from AUDIT_Table select min (NumberOfShares) from AUDIT_Table I get: 22678647.839110 -1845953000.000000 These values are inside the bounds of a numeric (19,6) so I'm not sure why the DBCC check fails. Any ideas to find out why it fails? Do I need to use DBCC PAGE? How would you troubleshoot this? Thanks, Mark.

• How to create a dynamic number of possibly children objects using partial views?

  - by NullReference

  I have a parent object that contains a property that is a list of children objects. I'd like to have it so that when the form loads to create the parent object a partial view is used to create the list of child objects. The problem is I have to idea how to have the list of children object populated. I can do one object ok, but a dynamic list of possible children is difficult. Any ideas? @Html.RenderPartial("_CreateChild", Model.Children); public class Parent { private List<Child> _list; public Guid Id { get; set; } public List<Child> Children { get { return _list; } set { _list = value; } } public Parent() { _list = new List<Child>(); } }

• Add function to existing JQuery plugin

  - by kralco626

  Is it possible to add a function to a plugin without modifying the actual plugin? Can I do something like this in my site's js file? $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); } or (function($){ $.fn.Watermark.Refresh = function() { $.Watermark.HideAll(); $.Watermark.ShowAll(); }; })(jQuery); neither worked, the first says $ is undefined, the second that jQuery is undefined... ideas? Solution: Either method works, just include the jquery file before the site js file.

• Determining whether a file is a duplicate

  - by Todd R

  Is there a reliable way to determine whether or not two files are the same? For example, two files with the same size and type may or may not be the same binarilly (yeah, I know it's not really a word). I assume that comparing one or two checksums of the files will help, but I wonder: How reliable are checksums at determining whether two files are different; what are the chances of two different files having the same checksum? Would reliability increase by applying additional checksum comparisons? Which checksum algorithm(s) would be the most efficient and/or reliable? Any ideas, suggestions or thoughts are appreciated! P.S. The code for this is being written in Java running on a nix system, but generic or platform agnostic input is most helpful.

• Get label height for fixed width

  - by Jonas

  Is there any way I can get the height of a label, if it hypothetically had a certain width? I've been trying with control.GetPreferredSize(size) like so: Dim wantedWidth as Integer = 100 dim ctrlSize as Size = label.GetPreferredSize(new Size(wantedWidth, 0)) because I thought that setting height = 0, would indicate a free height, but the height I get is way too small. I also tried to estimate the height of the label, using Graphics.MeasureString to calculate the equivalent area of the Label dim prefWidth as Integer = 100 dim estSize as SizeF = g.MeasureString(label.Text, label.Font) dim estHeight as Integer = (Integer)(estSize.Width * estSize.Height / prefWidth) but that yields the same result. Any ideas? I'm on .NET 2.0, unfortunately.

• how do i use htaccess to make http requests work properly

  - by Gabriel

  I currently have css and javascript file calls (amongst other things) like the following: href="/css/default.css" src="/js/ui_control.js" putting the preceding / in to make the files relative to the root. This works great when my page is in the root of the domain. However, I'm currently in the middle of transferring my site to a new hosting provider and as such have a temporary URL which is: HOST-IP/~username As such, all file calls are trying to be called from HOST-IP/css/default.css etc instead of within the ~username sub-folder. Of course I can wait until the domain name servers propagate but that's beside the point. How would I go about writing a rule in the .htaccess file that would redirect all file calls that start with a /, from going to HOST-IP/FILE-CALL, and instead to go to HOST-IP/~USERNAME/FILE-CALL. ? Any ideas?

• Python scope problems only when _assigning_ to a variable

  - by wallacoloo

  So I'm having a very strange error right now. I found where it happens, and here's the simplest code that can reproduce it. def parse_ops(str_in): c_type = "operator" def c_dat_check_type(t): print c_type #c_type = t c_dat_check_type("number") >>> parse_ops("12+a*2.5") If you run it as-is, it prints "operator". But if you uncomment that line, it gives an error: Traceback (most recent call last): File "<pyshell#212>", line 1, in <module> parse_ops("12+a*2.5") File "<pyshell#211>", line 7, in parse_ops c_dat_check_type("number") File "<pyshell#211>", line 4, in c_dat_check_type print c_type UnboundLocalError: local variable 'c_type' referenced before assignment Notice the error occurs on the line that worked just fine before. Any ideas what causes this and how I can fix this? I'm using Python 2.6.1.

• Modulation of adding new Strings -> Method calls.

  - by guesswork

  If I have a program that does the following: if(input=='abc'){do x} if(input=='def'){do y} In the future, I may want to add another piece of code like so: if(input=='ghy'){do x} As you can see, I am adding a new 'if' statement for a different conditional BUT using the SAME function X. The code in future has potential to have lots of different IF statements (or switches) all of which are comparing a string vs a string and then performing a function. Considering the future expansion, I was wondering if there is a possible 'neater', 'modular' way of achieving the same results. It's a shame I can't combine the String with a Method call in a hashtable (String, method) in Java. That way I could just store any new procedures inside a hashtable and grab the relevant method for that String. Any ideas? Thank you
