• Why cant i add Orientation property to the style setter in WPF

  - by nihi_l_ist

  When i write something like this: <Style x:Key="panelS"> <Setter Property="Orientation" Value="Horizontal" /> <Setter Property="DockPanel.Dock" Value="Top" /> </Style> I get the error that says: Cannot resolve the Style Property 'Orientation'. Verify that the owning type is the Style's TargetType, or use Class.Property syntax to specify the Property. Sure i have a Dock panel with many Stackpanels in it so i want to move Stackpanel's properties to the style. But there is this error and i dont quite understand what it means and what is the workaround(..i'd wanted not to assign Orientation on every Stackpanel).

• Function not recognized from jQuery

  - by coffeeaddict

  I've got a .js file that has this function in it: function showDialog(divID) { var dialogDiv = $(divID); dialogDiv.dialog ( { bgiframe: true, modal: true, autoOpen: false, show: 'blind' } ) And in my page this: <script type="text/javascript"> $(function() { $("input.invokeDialog").click.showDialog("#testDialog"); }); </script> I'm trying to figure out why it doesn't recognize my showDialog function. Is it not possible to reference it with the dot as I am doing? Do I need a jQuery specific function or syntax for it to know that it's a jQuery function or is there no such thing?

• Parantheses around method invokation: why is the compiler complaining about assignment?

  - by polygenelubricants

  I know why the following code doesn't compile: public class Main { public static void main(String args[]) { main((null)); // this is fine! (main(null)); // this is NOT! } } What I'm wondering is why my compiler (javac 1.6.0_17, Windows version) is complaining "The left hand side of an assignment must be a variable". I'd expect something like "Don't put parantheses around a method invokation, dummy!", instead. So why is the compiler making a totally unhelpful complaint about something that is blatantly irrelevant? Is this the result of an ambiguity in the grammar? A bug in the compiler? If it's the former, could you design a language such that a compiler would never be so off-base about a syntax error like this?

  - by nanoquetz9l

  Hello gals/guys, I am trying to use a custom configuration file instead of the default config.js file in the ckeditor root.

• Is it possible to match with decomposed sequences in F#?

  - by Ball

  I seem to remember an older version of F# allowing structural decomposition when matching sequences just like lists. Is there a way to use the list syntax while keeping the sequence lazy? I'm hoping to avoid a lot of calls to Seq.head and Seq.skip 1. I'm hoping for something like: let decomposable (xs:seq<'a>) = match xs with | h :: t -> true | _ -> false seq{ 1..100 } |> decomposable But this only handles lists and gives a type error when using sequences. When using List.of_seq, it seems to evaluate all the elements in the sequence, even if it is infinite.

• define method for instance of class

  - by aharon

  Let there be class Example defined as: class Example def initialize(test='hey') self.class.send(:define_method, :say_hello, lambda { test }) end end On calling Example.new; Example.new I get a warning: method redefined; discarding old say_hello. This, I conclude, must be because it defines a method in the actual class (which makes sense, from the syntax). And that, of course, would prove disastrous should there be multiple instances of Example with different values in their methods. Is there a way to create methods just for the instance of a class from inside that instance? Thanks so much.

• Using NVL function in SQL, please help!

  - by user363024

  I'm needing to select first and last name in a table which is working fine in the following SQL, but the part that isn't working is the NVL function. The file should show all pilots at a company that fly helicopters and IF they don't have a licence the field HT_NAME should come up as 'N/A' and the field for end hours flown should be 0. I've put NVL function in as my text details but it still isn't working. Have i made a syntax error? Help would be appreciated. Select E.EMP_NBR, E.EMP_FIRSTNAME || ' ' || E.EMP_LASTNAME, E.EMP_PILOT, ED.HT_NBR, NVL(HT.HT_NAME, 'N/A'), NVL(ED.END_HRS_FLOWN, 0), ED.END_LAST_ANNUAL_REVIEW_DATE From ENDORSEMENT ED, EMPLOYEE E, HELICOPTER_TYPE HT WHERE HT.HT_NBR = ED.HT_NBR (+) ORDER BY ED.END_HRS_FLOWN DESC, E.EMP_FIRSTNAME || ' ' || E.EMP_LASTNAME ASC; should make employees who are not pilots appear with a N/A under heli type and 0 under hours flown. It isn't working - even though I have tried multiple things to repair it.

• Double Inner Join generates unexpected error

  - by Itamar Marom

  In my database I have three tables: Users: UserID (Auto Numbering), UserName, UserPassword and a few other unimportant fields. PrivateMessages: MessageID (Auto Numbering), SenderID and a few other fields defining the message content. MessageStatus: MessageID, ReceiverID, MessageWasRead (Boolean) What I need is a query to which I input a user's id and I get all the private messages he has received. In addition, I also need to receive each message's sender UserName. For this I wrote the following query: SELECT Users.*, PrivateMessages.*, MessageStatus.* FROM PrivateMessages INNER JOIN Users ON PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageID WHERE MessageStatus.ReceiverID=[@userid]; But for some reason when I try saving it in my Access database, I get the following error (translated to English by me, since my office is in a different language): Syntax error (missing operator) at expression: "PrivateMessages.SenderID = Users.UserID INNER JOIN MessageStatus ON PrivateMessages.MessageID = MessageStatus.MessageI". Any ideas what could cause this? Thanks.

• Android: Best way/library to write an app that simply gets/sets your Facebook status, sends Facebook

  - by D.

  I have the Android Facebook-Connect library running in my emulator and I'm able to set my status with the Facebook API I have setup. However, I don't know where to go from there? Am I supposed to use the session key that this library allows me to get and make some Facebook API calls? I haven't found any code examples to even see what the proper syntax is. Am I better off using another library? I tried fbrocket with limited luck(I get a "server error 104 - Incorrect signature"). Thanks for any help.

• Add Attribute (System.Attribute variety) to .aspx page - not the code-behind

  - by Macho Matt

  I am creating a custom Attribute (extending System.Attribute). I know I can put it on another class easily enough by doing the following. [MattsAttribute] public class SomeClassWhichIsACodeBehind { However, I need to be able to test this attribute easily, and putting it in the code-behind would cause a lot of extra effort to get it deployed to an environment which would respond to the behavior of attribute. What I would like to do: declaratively apply this attribute to the .aspx page itself (which is really just another class that inherits from the code-behind). Is this possible? If so, what is the proper syntax for doing this?

• How to use parameter variable in xslt

  - by Abbi

  Hi I am new to xslt so please let me know whats wrong with my syntax here. If I compare with a Constant value of '880.50' I get the desired result. But if I try to do the samething with parameter being passed I get nothing. The code snippet is as under. <xsl:template name="ShowJourneyLegs" > <xsl:param name="TotalFare" /> <Key4><xsl:value-of select='$TotalFare'/></Key4> <JourneyLegKeys><xsl:value-of select="/FareSearchResponse/CompleteItineraryFares/AirFare[@Total = '880.50']/JourneyLegKeys/Key[1]"/></JourneyLegKeys> <JourneyLeg><xsl:value-of select="/FareSearchResponse/CompleteItineraryFares/AirFare[@Total = '$TotalFare']/JourneyLegKeys/Key[1]"/></JourneyLeg> </xsl:template>

• JavaScript using toString on a Function object to read text content

  - by mseeley

  Calling toString() on the function below returns different strings across browsers. I understand this is because ECMA-262 15.3.4.2 leaves wiggle room for each vendor. Chrome returns the comments in addition to all syntax. Sadly Firefox 3.6 omits the comments. Based on Firefox's behavior I haven't tested IE, Opera, or Safari. function foo() { /* comment */ var bar = true; } Specifically, I am attempting to embed meta data within a specially formatted comment block within a function. Later the return value of the functions toString() method would be parsed and values returned as an object. I've been unable to locate compatibility tables or alternatives to toString(). Does the community have any ideas? Btw, pre-processing JS files isn't an option. :( Thanks a lot. :)

• Can I Use ASP.NET Wizard Control to Insert Data into Multiple Tables?

  - by SidC

  Hello All, I have an ASP.NET 3.5 webforms project written in VB that involves a multi-table SQL Server insert. That is, I want the customer to input all their contact information, order details etc. into one control (thinking wizard control). Then, I want to call a stored procedure that does the insert into the respective database tables. I'm familiar and comfortable with the ASP.NET wizard control. However, all the examples I've seen in my searches pertain to inserting data into one table. Questions: 1. Given a typical order process - customer information, order information, order details - should a wizard control be used to insert data into multiple database tables? If not, what controls/workflow do you suggest? 2. I've set primary keys and indexes on my order details, orders and customers tables. Is there special stored procedure syntax to use to ensure that referential integrity is maintained through the insert process? Thanks, Sid

• Renamed MySQL table not renamed for INSERT queries?

  - by Austin Hyde

  After renaming one of my MySQL MyISAM tables from test_tablename to tablename, I have found that if I try to execute an INSERT (or REPLACE) query, I get the following message: 1146: Table 'dbname.test_tablename' doesn't exist I have triple-checked my database abstraction code, and verified this by running the query directly on the server. According to the MySQL server, the CREATE TABLE syntax is tablename, as expected, and when I run SHOW TABLES, it lists tablename as expected. Is there any reason for this to happen? More importantly, is there an easier way to fix this than dumping, dropping, re-creating, and reloading the table?

• Value was either too large or too small for an Int16 error

  - by Barlow Tucker

  I am working on fixing a bug in VB that is giving this error. I am new to VB, so there is some syntax that I am not fully understanding. The code that is throwing the error says: .Row(itemIndex).Item("parentIndex") = CLng(oID) + 1000000 I understand that adding 1000000 is too much for an int16. I can't change that value (not right now anyway). What I don't understand, and can't seem to find, is what .Row is referring too. Any ideas?

• Is the ruby operator ||= intelligent?

  - by brad

  I have a question regarding the ||= statement in ruby and this is of particular interest to me as I'm using it to write to memcache. What I'm wondering is, does ||= check the receiver first to see if it's set before calling that setter, or is it literally an alias to x = x || y This wouldn't really matter in the case of a normal variable but using something like: CACHE[:some_key] ||= "Some String" could possibly do a memcache write which is more expensive than a simple variable set. I couldn't find anything about ||= in the ruby api oddly enough so I haven't been able to answer this myself. Of course I know that: CACHE[:some_key] = "Some String" if CACHE[:some_key].nil? would achieve this, I'm just looking for the most terse syntax.

• Generate accessors in Visual C++ 2008

  - by gramm

  Hi, I'm trying to generate the accessors and mutators for my variables automatically, but just can't find a way. I tried the right-click/refactor... solution, but the refactor item doesn't appear. I'm not in the mood right now to learn how to write a macro to do this, and I don't have the money to buy a commercial solution (internship student). Any help is welcome, I don't feel like writing all my get/set by hand. note : it's C++ so the {get;set} syntax doesn't work (or does it ?).

• How do I define the default background color for window instances in a shared ResourceDictionary?

  - by Nicholas

  I can't seem to set a default background color for all of my windows in my application. Does anyone know how to do this? Currently I'm setting a theme in my App.xaml file like this. <Application> <Application.Resources> <ResourceDictionary Source="Themes/SomeTheme.xaml" /> This basically styles my entire application. Inside of SomeTheme.xaml I am trying to set a default color for all of my windows like this. <Style TargetType="{x:Type Window}"> <Setter Property="Background" Value="{DynamicResource MainColor}" /> </Style> This syntax works on a type of Button, but is completely ignored for Window. What am I doing wrong? Is there something special I have to do for a Window type.

• Optional parens in Ruby for method with uppercase start letter?

  - by RasmusKL

  I just started out using IronRuby (but the behaviour seems consistent when I tested it in plain Ruby) for a DSL in my .NET application - and as part of this I'm defining methods to be called from the DSL via define_method. However, I've run into an issue regarding optional parens when calling methods starting with an uppercase letter. Given the following program: class DemoClass define_method :test do puts "output from test" end define_method :Test do puts "output from Test" end def run puts "Calling 'test'" test() puts "Calling 'test'" test puts "Calling 'Test()'" Test() puts "Calling 'Test'" Test end end demo = DemoClass.new demo.run Running this code in a console (using plain ruby) yields the following output: ruby .\test.rb Calling 'test' output from test Calling 'test' output from test Calling 'Test()' output from Test Calling 'Test' ./test.rb:13:in `run': uninitialized constant DemoClass::Test (NameError) from ./test.rb:19:in `<main>' I realize that the Ruby convention is that constants start with an uppercase letter and that the general naming convention for methods in Ruby is lowercase. But the parens are really killing my DSL syntax at the moment. Is there any way around this issue?

• Drupal 6 devel module dd() function not writing to drupal_debug.txt file

  - by Mike Munroe

  I am running a local development Drupal site on a Windows machine. I am trying to use the dd($data, $label = NULL) function from the devel module to help debug. Using this function, should write debug info to a drupal_debug.txt file in the /tmp folder on the machine where the Drupal site is hosted. On my Windows machine, although I am using this function, the drupal_debug.txt file is not getting created anywhere, leading me to believe I am using the function incorrectly. Here is a snippet of how I am using it, <?php $test = "this is my test"; dd($test, $label = NULL); I am looking for an example of the correct syntax for the dd($data, $label = NULL) function. I have the Devel module enabled.

• Pass property to access using .NET

  - by BitFiddler

  I'm fairly sure this is possible, but what I want to do is have a generic method where I can pass in an object along with a Expression that will tell the method which Property to use in it's logic. Can anyone get me started on the syntax for something like this? Essentially what I would like to code is something like: Dim firstNameMapper as IColumnMapper = new ColumnMapper(of Author)(Function(x) x.FirstName) Dim someAuthorObject as new Author() fistNameMapper.Map("Richard", someAuthorObject) Now the mapper object would know to set the FirstName property to "Richard". Now using a Function here won't work, I know this... I'm just trying to give an idea what I'm trying to work towards. Thanks for any help!

• String Functions in IIS Url Rewrite Module

  - by Nariman

  The IIS URL Rewrite Module ships with 3 built-in functions: * ToLower - returns the input string converted to lower case. * UrlEncode - returns the input string converted to URL-encoded format. This function can be used if the substitution URL in rewrite rule contains special characters (for example non-ASCII or URI-unsafe characters). * UrlDecode - decodes the URL-encoded input string. This function can be used to decode a condition input before matching it against a pattern. The functions can be invoked by using the following syntax: {function_name:any_string} The question is: can this list be extended by introducing a Replace function that's available for changing values within a rewrite rule action or condition? Another way to frame the question: is there any way to do a global replace on a URL coming in using this module? It seems that you're limited to using regular expressions and back-references to construct strings, without a search/replace functionality to replace every X with Y in {REQUEST_URI} before issuing a redirect.

I need to use: server.framework.busy?() This leads to an error: SyntaxError: invalid syntax How can I call this function? Or am I reading the ruby code wrong and implementing it wrongly.

• Are there any context-sensitive code search tools?

  - by Vicky

  I have been getting very frustrated recently in dealing with a massive bulk of legacy code which I am trying to get familiar with. Say I try to search for a particular function call, I get loads of results that turn out to be completely irrelevant; some of them are easy to spot, eg a comment saying // Fixed functionality in foo() so don't need to handle this here any more But others are much harder to spot manually, because they turn out to be calls from other functions in modules that are only compiled in certain cases, or are part of a much larger block of code that is #if 0'd out in its entirety. What I'd like would be a search tool that would allow me to search for a term and give me the choice to include or exclude commented out or #if 0'd out code. Then the search results would be displayed alongside a list of #defines that are required in order for that snippet of code to be relevant. I'm working in C / C++, but other than the specific comment syntax I guess the techniques should be more generally applicable. Does such a tool exist?

• Why is url not registered?(Drupal 6.x)

  - by Andrew

  I'm using hook_menu to register new url so that accessing this url would return some data to ajax function. As title suggested, this url is not registered. How do I know that? I've tried typing this in address bar but, drupal, return main template only rather than the tests string that I created. I'm positive that my module is working for php issues error if I intentionally write wrong syntax. And, yes, I clear cache whenever I make changes. Here's the code - function test_menu() { $my_form['test'] = array( 'title' => 'Test address', 'page callback' => 'test', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function test(){ $a= "testing"; return $a; }
