• Specific programming text editor for simple open/close editing

  - by queen3

  I'm looking for very specific text editor: Closes on ESC, no project management or tabs Syntax highlighting - preferably with color themes (e.g. can apply different color themes without changing C# coloring definition) or, at least, can load/save themes; support for C/C#/XML/HTML/JavaScript/etc - common MS/.NET world - out of box Configurable keys, or: Shift-Tab shifts blocks XML/HTML auto-completion support - well, optional I use synplus plugin for Total Commander currently, but it has few drawbacks (e.g. crashes sometimes ;-), no auto-completion, etc). Basically I want fast Visual-Studio-like editor that I open, do edits, and then close using ESC. I remember I tried Notepad++, etc - most of them open files in tabs, don't close on ESC... - that is, behave like IDE. At least I've just downloaded Notepad++, it doesn't close on ESC even if I setup keybindings to do so. Autocompletion is optional (though it is to be simple as just tags completion), what I really look for is closing on ESC, not getting in the way with all the tabs and IDE-like, and good coloring. Plus shift-tab is must have for blocks manipulation. Update: any open-source one that I can easily tweak to close on ESC? ;-) Seems like ESC (and reasonable color highlighting) is the core requirement. I've just tried many editors - Programmer's Notepad, E, Crimson, etc - I can't set any of them to close on ESC. Any external tool to close selected program on ESC? ;-) UPDATE: Hm, found an awesome utility for my latest thought: http://www.autohotkey.com. Easy to setup to close any window on ESC (as well as many other tricks). Seems like the most tough requirements is gone - I can use ANY text editor ;-)

• Make seems to think a prerequisite is an intermediate file, removes it

  - by James

  For starters, this exercise in GNU make was admittedly just that: an exercise rather than a practicality, since a simple bash script would have sufficed. However, it brought up interesting behavior I don't quite understand. I've written a seemingly simple Makefile to handle generation of SSL key/cert pairs as necessary for MySQL. My goal was for make <name> to result in <name>-key.pem, <name>-cert.pem, and any other necessary files (specifically, the CA pair if any of it is missing or needs updating, which leads into another interesting follow-up exercise of handling reverse deps to reissue any certs that had been signed by a missing/updated CA cert). After executing all rules as expected, make seems to be too aggressive at identifying intermediate files for removal; it removes a file I thought would be "safe" since it should have been generated as a prereq to the main rule I'm invoking. (Humbly translated, I likely have misinterpreted make's documented behavior to suit my expectation, but don't understand how. ;-) Edited (thanks, Chris!) Adding %-cert.pem to .PRECIOUS does, of course, prevent the deletion. (I had been using the wrong syntax.) Makefile: OPENSSL = /usr/bin/openssl # Corrected, thanks Chris! .PHONY: clean default: ca clean: rm -I *.pem %: %-key.pem %-cert.pem @# Placeholder (to make this implicit create a rule and not cancel one) Makefile: @# Prevent the catch-all from matching Makefile ca-cert.pem: ca-key.pem $(OPENSSL) req -new -x509 -nodes -days 1000 -key ca-key.pem $@ %-key.pem: $(OPENSSL) genrsa 2048 $@ %-cert.pem: %-csr.pem ca-cert.pem ca-key.pem $(OPENSSL) x509 -req -in $ $@ Output: $ make host1 /usr/bin/openssl genrsa 2048 ca-key.pem /usr/bin/openssl req -new -x509 -nodes -days 1000 -key ca-key.pem ca-cert.pem /usr/bin/openssl genrsa 2048 host1-key.pem /usr/bin/openssl req -new -days 1000 -nodes -key host1-key.pem host1-csr.pem /usr/bin/openssl x509 -req -in host1-csr.pem -days 1000 -CA ca-cert.pem -CAkey ca-key.pem -set_serial 01 host1-cert.pem rm host1-csr.pem host1-cert.pem This is driving me crazy, and I'll happily try any suggestions and post results. If I'm just totally noobing out on this one, feel free to jibe away. You can't possibly hurt my feelings. :)

• How can I 'transpose' my data using SQL and remove duplicates at the same time?

  - by Remnant

  I have the following data structure in my database: LastName FirstName CourseName John Day Pricing John Day Marketing John Day Finance Lisa Smith Marketing Lisa Smith Finance etc... The data shows employess within a business and which courses they have shown a preference to attend. The number of courses per employee will vary (i.e. as above, John has 3 courses and Lisa 2). I need to take this data from the database and pass it to a webpage view (asp.net mvc). I would like the data that comes out of my database to match the view as much as possible and want to transform the data using SQl so that it looks like the following: LastName FirstName Course1 Course2 Course3 John Day Pricing Marketing Finance Lisa Smith Marketing Finance Any thoughts on how this may be achieved? Note: one of the reasons I am trying this approach is that the original data structure does not easily lend itself to be iterated over using the typical mvc syntax: <% foreach (var item in Model.courseData) { %> Because of the duplication of names in the orignal data I would end up with lots of conditionals in my View which I would like to avoid. I have tried transforming the data using c# in my ViewModel but have found it tough going and feel that I could lighten the workload by leveraging SQL before I return the data. Thanks.

• How to accurately parse smtp message status code (DSN)?

  - by Geo

  RFC1893 claims that status codes will come in the format below you can read more here. But our bounce management system is having a hard time parsing error status code from bounce messages. We are able to get the raw message, but depending on the email server the code will come in different places. Is there any rule on how to parse this type of messages to obtain better results. We are not looking for the 100% solution but at least 80%. This document defines a new set of status codes to report mail system conditions. These status codes are intended to be used for media and language independent status reporting. They are not intended for system specific diagnostics. The syntax of the new status codes is defined as: status-code = class "." subject "." detail class = "2"/"4"/"5" subject = 1*3digit detail = 1*3digit White-space characters and comments are NOT allowed within a status- code. Each numeric sub-code within the status-code MUST be expressed without leading zero digits. The quote above from the RFC tells one thing but then the text below from a leading tool on bounce management says something different, where I can get a good source of standard status codes: Return Code Description 0 UNDETERMINED - (ie. Recipient Reply) 10 HARD BOUNCE - (ie. User Unknown) 20 SOFT BOUNCE - General 21 SOFT BOUNCE - Dns Failure 22 SOFT BOUNCE - Mailbox Full 23 SOFT BOUNCE - Message Too Large 30 BOUNCE - NO EMAIL ADDRESS. VERY RARE! 40 GENERAL BOUNCE 50 MAIL BLOCK - General 51 MAIL BLOCK - Known Spammer 52 MAIL BLOCK - Spam Detected 53 MAIL BLOCK - Attachment Detected 54 MAIL BLOCK - Relay Denied 60 AUTO REPLY - (ie. Out Of Office) 70 TRANSIENT BOUNCE 80 SUBSCRIBE Request 90 UNSUBSCRIBE/REMOVE Request 100 CHALLENGE-RESPONSE

• Bash and regex problem : check for tokens entered into a Coke vending machine

  - by Michael Mao

  Hi all: Here is a "challenge question" I've got from Linux system programming lecture. Any of the following strings will give you a Coke if you kick: L = { aaaa, aab, aba, baa, bb, aaaa"a", aaaa"b", aab"a", … ab"b"a, ba"b"a, ab"bbbbbb"a, ... } The letters shown in wrapped double quotes indicate coins that would have fallen through (but those strings are still part of the language in this example). Exercise (a bit hard) show this is the language of a regular expression And this is what I've got so far : #!/usr/bin/bash echo "A bottle of Coke costs you 40 cents" echo -e "Please enter tokens (a = 10 cents, b = 20 cents) in a sequence like 'abba' :\c" read tokens #if [ $tokens = aaaa ]||[ $tokens = aab ]||[ $tokens = bb ] #then # echo "Good! now a coke is yours!" #else echo "Thanks for your money, byebye!" if [[ $token =~ 'aaaa|aab|bb' ]] then echo "Good! now a coke is yours!" else echo "Thanks for your money, byebye!" fi Sadly it doesn't work... always outputs "Thanks for your money, byebye!" I believe something is wrong with syntax... We didn't provided with any good reference book and the only instruction from the professor was to consult "anything you find useful online" and "research the problem yourself" :( I know how could I do it in any programming language such as Java, but get it done with bash script + regex seems not "a bit hard" but in fact "too hard" for anyone with little knowledge on something advanced as "lookahead"(is this the terminology ?) I don't know if there is a way to express the following concept in the language of regex: Valid entry would consist of exactly one of the three components : aaaa, aab and bb, regardless of order, followed by an arbitrary sequence of a or b's So this is what is should be like : (a{4}Ua{2}bUb{2})(aUb)* where the content in first braces is order irrelevant. Thanks a lot in advance for any hints and/or tips :)

• as3crypto PEM.readRSAPublicKey returns null

  - by www.jefferyfernandez.id.au

  I am trying to implement a bit of encryption in my Air application while communication with a PHP backend server. For this purpose I am using as3crypto library and I can't read the public key to make the encryption possible. Here is my action script code: var rsa:RSAKey = PEM.readRSAPublicKey(this.readApplicationFileContents('server.crt')); if ( rsa ) { var encodeSource:ByteArray = Hex.toArray(Hex.fromString("Hello World")); var encodeDestination:ByteArray = new ByteArray; var encodeDestination2:ByteArray = new ByteArray; rsa.encrypt(encodeSource, encodeDestination, encodeSource.length) rsa.decrypt(encodeDestination, encodeDestination2, encodeDestination.length); trace(encodeDestination2.toString()); } private function readApplicationFileContents(filePath:String):String { var fileObject:File = File.applicationDirectory.resolvePath(filePath); var fileStream:FileStream = new FileStream(); fileStream.open(fileObject, FileMode.READ); var fileContents:String = fileStream.readUTFBytes(fileStream.bytesAvailable); return(fileContents); } readApplicationFileContents function returns the proper certificate contents as a string. But rsa variable always returns null. It would have been easier if I was able to compile the as3crypto library so I can debug through the source, but I can't get the library to compile and can't find any instructions to do the same. Anyone have a clue what's wrong? PS. Sorry first time poster and I can't seem to get the syntax highlighting right. Must be Chrome is not working well with the editor.

• How to get around the jslint error 'Don't make functions within a loop.'

  - by Ernelli

  I am working on making all of our JS code pass through jslint, sometimes with a lot of tweaking with the options to get legacy code pass for now on with the intention to fix it properly later. There is one thing that jslint complains about that I do not have a workround for. That is when using constructs like this, we get the error 'Don't make functions within a loop.' for (prop in newObject) { // Check if we're overwriting an existing function if (typeof newObject[prop] === "function" && typeof _super[prop] === "function" && fnTest.test(newObject[prop])) { prototype[prop] = (function (name, func) { return function () { var result, old_super; old_super = this._super; this._super = _super[name]; result = func.apply(this, arguments); this._super = old_super; return result; }; })(prop, newObject[prop]); } This loop is part of a JS implementation of classical inheritance where classes that extend existing classes retain the super property of the extended class when invoking a member of the extended class. Just to clarify, the implementation above is inspired by this blog post by John Resig. But we also have other instances of functions created within a loop. The only workaround so far is to exclude these JS files from jslint, but we would like to use jslint for code validation and syntax checking as part of our continuous integration and build workflow. Is there a better way to implement functionality like this or is there a way to tweak code like this through jslint?

• Perl - How to get the number of elements in an anonymous array, for concisely trimming pathnames

  - by NXT

  Hi Everyone, I'm trying to get a block of code down to one line. I need a way to get the number of items in a list. My code currently looks like this: # Include the lib directory several levels up from this directory my @ary = split('/', $Bin); my @ary = @ary[0 .. $#ary-4]; my $res = join '/',@ary; lib->import($res.'/lib'); That's great but I'd like to make that one line, something like this: lib->import( join('/', ((split('/', $Bin)) [0 .. $#ary-4])) ); But of course the syntax $#ary is meaningless in the above line. Is there equivalent way to get the number of elements in an anonymous list? Thanks! PS: The reason for consolidating this is that it will be in the header of a bunch of perl scripts that are ancillary to the main application, and I want this little incantation to be more cut & paste proof. Thanks everyone There doesn't seem to be a shorthand for the number of elements in an anonymous list. That seems like an oversight. However the suggested alternatives were all good. I'm going with: lib->import(join('/', splice( @{[split('/', $Bin)]}, 0, -4)).'/lib'); But Ether suggested the following, which is much more correct and portable: my $lib = File::Spec->catfile( realpath(File::Spec->catfile($FindBin::Bin, ('..') x 4)), 'lib'); lib->import($lib);

• Perl, share package variable without Export

  - by Mike

  I'm creating a group of Perl scripts, and I would like to have one package store a group of constants. I don't want to export them using Exporter because there will be quite a few and I don't want to pollute the namespace. Since there will be so many, I don't want to require the user to be forced to manually specify which they will be using. I think the best way to just use the packagename::var syntax, however it doesn't seem to be working as I expect it to. I illustrate this problem in the below code This is settings.pm, the module that will hold the global settings #!/usr/bin/perl #settings.pm use strict; use warnings; package settings; our $foo="hello world"; 1; Below is the main script #!/usr/bin/perl #script.pl use strict; use warnings; use settings; print settings::$foo; It gives this error message instead or printing hello world Bad name after settings:: at ./script.pl line 8.

• Sql serve Full Text Search with Containstable is very slow when Used in JOIN!

  - by Bob

  Hello, I am using sql 2008 full text search and I am having serious issues with performance depending on how I use Contains or ContainsTable. Here are sample: (table one has about 5000 records and there is a covered index on table1 which has all the fields in the where clause. I tried to simplify the statements so forgive me if there is syntax issues.) Scenario 1: select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select top 1 * from containstable(table1,*, 'something') as t2 where t2.[key]=t1.id) results: 10 second (very slow) Scenario 2: select * from table1 as t1 join containstable(table1,*, 'something') as t2 on t2.[key] = t1.id where t1.field1=90 and t1.field2='something' results: 10 second (very slow) Scenario 3: Declare @tbl Table(id uniqueidentifier primary key) insert into @tbl select {key] from containstable(table1,*, 'something') select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select id from @tbl as tbl where id=req1.id) results: fraction of a second (super fast) Bottom line, it seems if I use Containstable in any kind of join or where clause condition of a select statement that also has other conditions, the performance is really bad. In addition if you look at profiler, the number of reads from the database goes to the roof. But if I first do the full text search and put results in a table variable and use that variable everything goes super fast. The number of reads are also much lower. It seems in "bad" scenarios, somehow it gets stuck in a loop which causes it to read many times from teh database but of course I don't understant why. Now the question is first of all whyis that happening? and question two is that how scalable table variables are? what if it results to 10s of thousands of records? is it still going to be fast. Any ideas? Thanks

• Foreach is crashing script, but no errors reported.

  - by ILMV

  So I've created this smarty function to get images from my flickr photostream using SimplePie... simple really, or so it should be. The problem I'm having is the foreach will crash the script, this doesn't happen if I put an exit after the closing foreach, of course because of this the rest of my script doesn't execute. The problem also completely subsides if I remove the foreach, I've tested it and it's not the contents of the foreach, but the loop itself. Error reporting is turned on but I don't get any, I also tried messing with the memory_limit, with no luck. Anyone know why this foreach is killing my script? Thanks! function smarty_function_flickr ($params, &$smarty) { require_once('system/library/SimplePie/simplepie.inc'); require_once('system/library/SimplePie/idn/idna_convert.class.php'); $flickr=new flickr(); /** * Set up SimplePie with all default values using shorthand syntax. */ $feed = new SimplePie($params['feed'], 'system/library/SimplePie/cache', '600'); $feed->handle_content_type(); /** * What sizes should we use? * Choices: square, thumb, small, medium, large. */ $thumb = 'square'; $full = 'medium'; $output = array(); $counter=0; // If I comment this foreach out the problem subsides, I know it is not the code within the foreach foreach ($feed->get_items() as $item) { $url = $flickr->image_from_description($item->get_description()); $output[$counter]['title'] = $item->get_title(); $output[$counter]['image'] = $flickr->select_image($url, $full); $output[$counter]['thumb'] = $flickr->select_image($url, $thumb); $counter++; } // Set template variables and template $smarty->assign('flickr',$output); $smarty->display('forms/'.$params['template'].'.tpl'); }

• Pydev and Django: Shell not finding certain modules?

  - by Rosarch

  I am developing a Django project with PyDev in Eclipse. For a while, PyDev's Django Shell worked great. Now, it doesn't: >>> import sys; print('%s %s' % (sys.executable or sys.platform, sys.version)) C:\Python26\python.exe 2.6.4 (r264:75708, Oct 26 2009, 08:23:19) [MSC v.1500 32 bit (Intel)] >>> >>> from django.core import management;import mysite.settings as settings;management.setup_environ(settings) Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named mysite.settings >>> The dev server runs just fine. What could I be doing wrong? The models module is also conspicuously absent: >>> import mysite.myapp.models Traceback (most recent call last): File "<console>", line 1, in <module> ImportError: No module named mysite.myapp.models On the normal command line, outside of PyDev, the shell works fine. Why could this be happening?

• PageMethod with Custom Handler

  - by Mister Cook

  I have a page based web method which works fine, using [WebMethod], i.e [WebMethod] public static void DoSomethingOnTheServer() { } I also have a custom page handler to make SEO friendly URLs possible, e.g http://localhost/MySite/A_nice_url.ext = http://localhost/MySite/page.aspx?id=1 I am using Server.Transfer in my ProcessRequest handler to achieve this. This all works fine. Also, my page method works fine when the user requests the URL such as: http://localhost/MySite/page.aspx?id=1 However, when the user requests the custom handled URL, i.e. http://localhost/MySite/A_nice_url.ext The client reports that the PageMethod has been successfully completed, but it has not been called at all. I'm guessing it has something to do with my custom handler, so I have modified it to include PathInfo: public void ProcessRequest(HttpContext context) { // ... (code to determine id) ... // Transfer to the required page string actualPath = "~/page.aspx" + context.Request.PathInfo + "?id=" + determinedId; context.Server.Transfer(actualPath); } So now if a PageMethod is called, it will result in: http://localhost/MySite/page.aspx/DoSomethingOnTheServer?id=1 I'm wondering if this is the correct syntax for calling a PageMethod. When I try Server.Transfer reports: Error executing child request for /MySite/page.aspx/DoSomethingOnTheServer I've experimented with HttpContext.RewritePath but not sure how to actually make it perform the request. This does not seem to work, any ideas?

• Two-phase lookup: can I avoid "code bloat"?

  - by Pietro

  Two-phase lookup question: Is there a more synthetic way to write this code, i.e. avoiding all those "using" directives? I tried with "using CBase<T>;", but it is not accepted. #include <iostream> template <typename T> class CBase { protected: int a, b, c, d; // many more... public: CBase() { a = 123; } }; template <typename T> class CDer : public CBase<T> { // using CBase<T>; // error, but this is what I would like using CBase<T>::a; using CBase<T>::b; using CBase<T>::c; //... public: CDer() { std::cout << a; } }; int main() { CDer<int> cd; } In my real code there are many more member variables/functions, and I was wondering if it is possible to write shorter code in some way. Of course, using the CBase::a syntax does not solve the problem... Thank's! gcc 4.1 MacOS X 10.6

• MS Query Analyzer / Management Studio replacement?

  - by kprobst

  I've been using SQL Server since version 6.5 and I've always been a bit amazed at the fact that the tools seem to be targeted to DBAs rather than developers. I liked the simplicity and speed of the Query Analyzer for example, but hated the built-in editor, which was really no better than a syntax coloring-capable Notepad. Now that we have Management Studio the management part seems a bit better but from a developer standpoint the tools is even worse. Visual Studio's excellent text editor... without a way to customize keyboard bindings!? Don't get me started on how unusable is the tree-based management hierarchy. Why can't I re-root the tree on a list of stored procs for example the way the Enterprise Manager used to allow? Now I have a treeview that needs to be scrolled horizontally, which makes it eminently useless. The SQL server support in Visual Studio is fantastic for working with stored procedures and functions, but it's terrible as a general ad hoc data query tool. I've tried various tools over the years but invariably they seem to focus on the management side and shortchange the developer in me. I just want something with basic admin capabilities, good keyboard support and requisite DDL functionality (ideally something like the Query Analyzer). At this point I'm seriously thinking of using vim+sqlcmd and a console... I'm that desperate :) Those of you who work day in and day out with SQL Server and Visual Studio... do you find the tools to be adequate? Have you ever wished they were better and if you have found something better, could you share please? Thanks!

• PHP site keeps opening to blank page, no errors.

  - by gene

  First, the premises: PHP loaded on IIS6 on Win2003 STD R2 SP2, PHP_5213 using FastCGI, MySQL_5145. Customer sent me the site files, which I unzipped to C:\InetPub\wwwroot\<site root>, then I created a new site in IIS, pointed to <site root>, added test.php to the site files for testing and it works, but visiting index.php produces a blank page with no errors. The readme.txt file present makes reference to application.php and explains root folder var and sets it to a non-existent file. I don't know PHP syntax, but I tried several logical changes with zero results. At this point I'm not even sure if that is the problem anymore. With PHP, MySQL & site debugging have put in over 20 hours. Still confused, I have resorted to heavy drug use and purchased a small firearm, loaded with a single round (even this seemed to take an inordinate amount of time). I've given up all hope. Someone please help save a new server and/or old administrator.

• TCL TDom: Looping through Objects

  - by pws5068

  Using TDom, I would like to cycle through a list of objects in the following format: <object> <type>Hardware</type> <name>System Name</name> <description>Basic Description of System.</description> <attributes> <vendor>Dell</vendor> <contract>MM/DD/YY</contract> <supportExpiration>MM/DD/YY</supportExpiration> <location>Building 123</location> <serial>xxx-xxx-xxxx</serial> <mac>some-mac-address</mac> </attributes> </object> <object> <type>Software</type> <name>Second Object</name> ... Then I use TDom to make a list of objects: set dom [dom parse $xml] set doc [$dom documentElement] set nodeList [$doc selectNodes /systems/object] So far I've done this to (theoretically) select every "Object" node from the list. How can I loop through them? Is it just: foreach node $nodeList { For each object, I need to retrieve the association of each attribute. From the example, I need to remember that the "name" is "System Name", "vendor" is "Dell", etc. I'm new to TCL but in other languages I would use an object or an associative list to store these. Is this possible? Can you show me an example of the syntax to select an attribute in this manner?

• Rhino Commons and Rhino Mocks Reference Documents?

  - by Ogre Psalm33

  Ok, is it just me, or does there seem to be a lack of (easy to find) reference documentation for Rhino Commons and Rhino Mocks? My coworkers have started using Rhino Mocks and Rhino Commons (particularly the NHibernate stuff), and I found a few tutorial-ish examples, which were good. But when I see them making use of a class in their code--let's pick something like Rhino.Commons.NHRepository, for example--I have been having a hard time just finding someplace on the web that tells me what Rhino.Commons.NHRepository is or what it does. I like to learn by looking at real examples, but using this approach, it's very handy to look at what the full docs are for a class, instead of just the current context. Similarly, I saw IaMockedRepository.Expect(...) being used in some code, but it took me forever to finally find this page that explains the AAA syntax for Rhino Mocks, which made it clear to me. I've found the Ayende.com wiki on Rhino Commons, but that seems to have a number of broken links. To me, the Rhino libraries seem like a great set of libraries in need of some desperate community help in the documentation area (Of course, as we all know, documentation is not the forte of most coders, and incomplete docs are all too common). Does anyone know if this is something in the works, someplace that some volunteer documenters are needed, or is there some great reference docs out there that I have somehow missed to Rhino Mocks and Rhino Commons?

• Which Java Framework is best suited for a web application with reusable content/behavior

  - by Jacob

  I come from a .NET background and need to do a web project in Java. I have read a bit on all the different Java web frameworks out there: JSF, Stripes, Wicket, Tapestry etc. But I would like to hear from people with real-life expertise with these frameworks. Of course I want a framework that is up to date, supports AJAX, is cool and so on, but one of my main criteria is the ability to somehow create reusable components / tags. The customer needs to be able to move tags/components around without too much problem in order to customize it for their specific needs. In ASP.NET Webforms I would use custom controls and user controls for this, and in ASP.NET MVC I would use user controls as well as home made custom controls. So what Java frameworks excel in this? My own superficial research seems to conclude that JSF supports some kind of custom controls (Bear in mind i am not only talking about layout reuse, but also behavior reuse, so if for example the customer / client wants a customer list on page x and not only on page Y, he would simply put in a <jr:CustomerList runat="server" .... /> (fictional example with ASP.NET Webforms syntax)).

• How to get SQL Function run a different query and return value from either query?

  - by RoguePlanetoid

  I need a function, but cannot seem to get it quite right, I have looked at examples here and elsewhere and cannot seem to get this just right, I need an optional item to be included in my query, I have this query (which works): SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC This works within a Function, however the Manufacturer is Optional for this search - which is to find the description of a similar item, if none is present, the other query is: SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title ORDER BY LenDesc DESC Which is missing the Manufacturer, how to I get my function to use either query based on the Manufacturer Value being present or not. The reason is I will have a function which first checks an SKU for a Description, if it is not present - it uses this method to get a Description from a Similar Product, then updates the product being added with the similar product's description. Here is the function so far: ALTER FUNCTION [dbo].[GetDescriptionByTitleManufacturer] ( @Title varchar(400), @Manufacturer varchar(160) ) RETURNS TABLE AS RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC ) I've tried adding BEGINs and IF...ELSEs but get errors or syntax problems each way I try it, I want to be able to do something like this pseudo-function (which does not work): ALTER FUNCTION [dbo].[GetDescriptionByTitleManufacturer] ( @Title varchar(400), @Manufacturer varchar(160) ) RETURNS TABLE AS BEGIN IF (@Manufacturer = Null) RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title ORDER BY LenDesc DESC ) ELSE RETURN ( SELECT TOP 100 PERCENT SKU, Description, LEN(CONVERT(VARCHAR (1000),Description)) AS LenDesc FROM tblItem WHERE Title = @Title AND Manufacturer = @Manufacturer ORDER BY LenDesc DESC ) END

• Help creating a predicate for use with filteredArrayUsingPredicate

  - by johnbdh

  I am trying to learn how to use predicates and so am trying to replace the following working code with filteredArrayUsingPredicate... [filteredLocations removeAllObjects]; for (NSString *location in locations) { NSRange range = [location rangeOfString:query options:NSCaseInsensitiveSearch]; if (range.length > 0) { [filteredLocations addObject:location]; } } Instead I am trying.... [filteredLocations removeAllObjects]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"SELF contains %@", searchText]; [filteredLocations addObjectsFromArray: [locations filteredArrayUsingPredicate:predicate]]; I am not getting the same results with the predicate as I am with for loop rangeOfString. With the range of string for example searchText returns an 8 item array while with the same value returns only 2 with the predicate. Another example, hono will find honolulu in the locations array while it will not find anything using the predicate. As I understand it SELF represents the object object being evaluated ie. the locations array, so I think that is the correct syntax. Any help would be appreciated Thanks, John

• jQuery - Could use a little help with a content loader

  - by Kenny Bones

  Hi, I'm not very elite when it comes to JavaScript, especially the syntax. So I'm trying to learn. And in this process I'm trying to implement a content loader that basically removes all content from a div and inserts content from another div from a different document. I've tried to do this on this site: www.matkalenderen.no - Check the butt ugly link there. See what happens? I've taken the example from this site: http://nettuts.s3.cdn.plus.org/011_jQuerySite/sample/index.html#index But I'm not sure this example actually works the way I think it does. I mean, if the code just wipes out existing content from a div and inserts content from another div, why does the other webpages in this example include doctype and heading etc etc? Wouldn't you just need the div and it's content? Without all the other stuff "around"? Maybe I don't get how this works though. Thought it worked mosly like include really. This is my code however: $(document).ready(function() { var hash = window.location.hash.substr(1); var href = $('#dynloader a').each(function(){ var href = $(this).attr('href'); if(hash==href.substr(0,href.length-5)){ var toLoad = hash+'.html #container'; $('#container').load(toLoad) } }); $('#dynloader a').click(function(){ var toLoad = $(this).attr('href')+' #container'; $('#container').hide('fast',loadcontainer); $('#load').remove(); $('#wrapper').append('<span id="load">LOADING...</span>'); $('#load').fadeIn('normal'); window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-5); function loadcontainer() { $('#container').load(toLoad,'',showNewcontainer()) } function showNewcontainer() { $('#container').show('normal',hideLoader()); } function hideLoader() { $('#load').fadeOut('normal'); } return false; }); });

• Do overlays work correctly in Emacs for Windows?

  - by Cheeso

  I'm using Flymake on C# code, emacs v22.2.1 on Windows. The Flymake stuff has been working well for me. For those who don't know, you can read an overview of flymake, but the quick story is that flymake repeatedly builds the source file you are currently working on in the background, for the purpose of doing syntax checking. It then highlights the compiler warnings and erros in the current buffer. Flymake didn't work for C# initially, but I "monkey-patched it" and it works nicely now. If you edit C# in emacs, I highly recommend using flymake. The only problem I have is with the UI. Flymake highlights the errors and warnings nicely, and then inserts "overlays" with the full error or warning text. IF I hover the mouse pointer over the highlighted line in code, the overlay pops up. But as you can see, the overlay is truncated, and it doesn't display correctly. Flymake seems to be doing the right thing, it's the overlay part that seems broken. Do overlays work correctly in emacs for Windows? Where do I look to fix this?
