  • VS2010's "Public Property <PropertyName> As <DataType> vs. Public var

    - by Velika2
    In VS2008, I used to type Public Property <PropName> As <dataType> and hit the Enter key and the IDE editor would automatically expand it out to a full blown property block. Now, from what I understand, a new feature of 2010 is that the compiler automatically "expands" the short syntax above into the same IL code that you would get with the full property GET AND SET sub methods that were are accustomed to seeing before in the editor. But functionality, how the heck is this any different than just having a Public class level variable? If the only diff is what it compiles to and if otehrwise there is no functional difference, isn't the new way less efficient than the old since it involves more code than just having a class level memory variable? Public as I thought that if you weren't going to have code behind your properties that they were essentially the same. I guess the diffrenece is that they just added the keyword "Property" but functionality, their is no diff, eh?

  • Command-line input causes SyntaxError

    - by coson
    Good Day, I have a simple Python question that I'm having brain freeze on. This code snippet works. But when I substitue "258 494-3929" with phoneNumber, I get the following error below: # Compare phone number phone_pattern = '^\d{3} ?\d{3}-\d{4}$' # phoneNumber = str(input("Please enter a phone number: ")) if re.search(phone_pattern, "258 494-3929"): print "Pattern matches" else: print "Pattern doesn't match!" ####################################################### Pattern does not match Please enter a phone number: 258 494-3929 Traceback (most recent call last): File "pattern_match.py", line 16, in <module> phoneNumber = str(input("Please enter a phone number: ")) File "<string>", line 1 258 494-3929 ^ SyntaxError: invalid syntax C:\Users\Developer\Documents\PythonDemo> By the way, I did import re and tried using rstrip in case of the \n What else could I be missing?

  • Unknow Linking Error

    - by Nathan Campos
    I'm developing my own OS, but for this I need to touch on linking, then I've done this linking script to build it: ENTRY (loader) SECTIONS{ . = 0x00100000 .text : { *(.text) } .bss : { sbss = .; *(COMMON) *(.bss) ebss = .; } } .data ALIGN (0x1000) : { start_ctors = .; *(.ctor*) end_ctors = .; start_dtors = .; *(.dtor*) end_dtors = .; *(.data) } But when I try to link the things, I got some errors $ ld -T linker.ld -o kernel.bin loader.o kernel.o ld:linker.ld:5: syntax error $ What can I do?

  • Choosing MooTools over Google closure?

    - by Shekhar
    I am in a process to select javascript library for our new web application. This app is not very UI heavy but has forms, reports, search, calendars, tabs and target multiple countries like most web apps. We are a tiny team. Biggest concern is maintainability and readability of the code. We are Python programmers. After evaluating many other javascript frameworks we have narrowed down to mootools and google-closure. We loved mootools syntax. It took us no time to learn. It's like Python. On other hand we were stumped seeing private/public in google closure. It's tempting to go for mootools however, I would love to hear from you about specific advantages these frameworks offer over each other.

  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • Preventing focus on next form element after showing alert using JQuery

    - by digitalsanctum
    I have some text inputs which I'm validating when a user tabs to the next one. I would like the focus to stay on a problematic input after showing an alert. I can't seem to nail down the correct syntax to have JQuery do this. Instead the following code shows the alert then focuses on the next text input. How can I prevent tabbing to the next element after showing an alert? $('input.IosOverrideTextBox').bind({ blur: function(e) { var val = $(this).val(); if (val.length == 0) return; var pval = parseTicks(val); if (isNaN(pval) || pval == 0.0) { alert("Invalid override: " + val); return false; } }, focus: function() { $(this).select(); } });

  • Oracle: show parameters on error

    - by llappall
    When Oracle logs a parameterized SQL query failing, it shows "?" in place of the parameters, i.e. the query before replacing parameters. For example, "SELECT * FROM table where col like '?'" SQL state [99999]; error code [29902]; ORA-29902: error in executing ODCIIndexStart() routine ORA-20000: Oracle Text error: DRG-50901: text query parser syntax error on line 1, column 48 Is there a way to change logging so it shows the parameter values? The information above is absolutely useless unless I can see what the actual parsing problem was. In general, is there a way to set logs in Oracle to show parameters in parameterized query errors?

  • REST/ROA Architecture - Send database search/querying/filter/sorting parameters in URL? (>, <, IN, e

    - by DutrowLLC
    I'm building a REST interface to my application using ROA (Resource Oriented Architecture) . I'd like to give the client the ability to specify search parameters in URL. So a client could say "Give me all people who's: "first_name" is equal to "BOB" "age" is greater than "30" sort by "last_name" I was thinking something like: GET /PEOPLE/{query_parameters}/{sort_parameters} ...or perhaps GET /PEOPLE?query=<query_string>&sort=<sort_string> ...but I'm unsure what syntax would be good for specifying in the COLUMN_NAME-OPERATOR-VALUE triplicates. I was thinking perhaps something like: column_name.operator.value So the client could say: GET /PEOPLE?query=first_name.EQUALS.bob&query=age.GREATER_THAN.30&sort=last_name.ASCENDING I really don't want to re-invent the wheel here, are there some accepted ways that this is done? I am using Restlets, I don't know if that makes a difference.

  • C++/CLI com-Interop: Exposing a reference type property to VBA

    - by Adam
    After long hours of investigation on exposing C# property that accepts a reference type to VBA, I concluded that it was not possible. In brief, a C# property that is of type double[] or even an object cannot be consumed in VBA like this: ' Compile Error: Function or interface marked as restricted, ' or the function uses an Automation type not supported in Visual Basic oComExposedEarlyBinding.ObjectArray = VBArray ' Run-time error 424: Object required oComExposedEarlyBinding.PlainObject = VBArray Or for more details: C# property exposed to VBA (COM) : Run-time error '424': Object required I would like to know if C++/CLI would support such an option? i.e. Allowing a reference-type property to be exposed to VBA so that a syntax like the above is valid. N.B. You can achieve this by using late binding, but losing the intellisense is not an option.

  • How did Perl gain a reputation for being a write-only language?

    - by Andrew Grimm
    How did Perl gain a reputation (deserved, undeserved, or used to be deserved, no longer so) of being a "write only language"? Was it The syntax of the language Specific features that were available in the language Specific features not being available in the language (or at least old versions of it) The kind of tasks Perl was being used for The kind of people who use Perl (people who aren't full-time programmers) Criticism from people committed to another language Something else? Background: I'd like to know if some aspects that gave Perl the reputation of being write-only also apply to other languages (specifically ruby). Disclaimer: I recognise that Perl doesn't force people to do write-only code (can any language?), and that you can write bad code in any language.

  • Getting javascript mouse position relative to website prefferably without jQuery

    - by Constructor
    I've found this snippet on Ajaxian, but I can't seem to use the cursor.y (or cursor.x) as a variable and when the function is called as such it does not seem to work. Is there a syntax problem or something else? function getPosition(e) { e = e || window.event; var cursor = {x:0, y:0}; if (e.pageX || e.pageY) { cursor.x = e.pageX; cursor.y = e.pageY; } else { cursor.x = e.clientX + (document.documentElement.scrollLeft || document.body.scrollLeft) - document.documentElement.clientLeft; cursor.y = e.clientY + (document.documentElement.scrollTop || document.body.scrollTop) - document.documentElement.clientTop; } return cursor; } I'd preffer not to use jQuery UI if possible, since I've always thaught of jQuery and librarys as a bit of an overkill for most JS programing.

  • postgres store with composite value type, or a better way of attributing an inverted index

    - by Hassan Syed
    can't seem to figure out the syntax for populating a hstore with a value of composite type -- note: I do not want to convert a record to a hstore. select hstore('hello => ROW(1,2)'); I know it's something simple; However, google is not my friend today. use case : custom inverted index. The data is modelling an inverted index of lexemes, the composite data types are various probabilities related to the lexemes which I will use to implement document clustering. Does anyone know a better way of doing this ? I'm open to using an external system if it allows attaching attributes to key-posting pairs in the inverted index. I'd use something external if it had solid support for what I am trying to do, I suspect that sticking 3-10k lexemes per tuple and then doing batch processing on them is gonna be nasty as the whole hstore will have to be parsed and converted .

  • Rack::ResponseHeaders in rackup for Sinatra

    - by sevennineteen
    I think this is a very easy one, but I can't seem to get it right. Basically, I'm trying to use Rack middleware to set a default Cache-Control header into all responses served by my Sinatra app. It looks like Rack::ResponseHeaders should be able to do exactly what I need, but I get an error when attempting to use the syntax demonstrated here in my rackup file: use Rack::ResponseHeaders do |headers| headers['X-Foo'] = 'bar' headers.delete('X-Baz') end I was able to get Rack::Cache to work successfully as follows: use Rack::Cache, :default_ttl => 3600 However, this doesn't achieve exactly the output I want, whereas Rack::ResponseHeaders gives fine-grained control of the headers. FYI, my site is hosted on Heroku, and the required Rack gems are specified in my .gems manifest. Thanks! Update: After doing some research, it looks like the first issue is that Rack::ResponseHeaders is not found in the version of rack-contrib (0.9.2) which was installed. I'll start by looking into that.

  • Accessing E4X nodes having special characters in name without breaking binding chain in flex.

    - by Jonas
    I am using E4X to bind some values from xml in flex 3. There is a problem when xml tag's (or attribute's) name has special character in it: having xml content var xml:XML = <tag> <special-name att="val" /> </tag> special-name could not be accessed using xml.special-name.@att because it is interpreted as subtraction, on the other hand using square bracket notation xml['special-name'].@att breaks binding chain. Is there an elegant way to solve this (like special language syntax) without writing custom binding setters and listeners?

  • How does mysql define DISTINCT()

    - by goran
    AFAIK SQL defines two uses of DISTINCT keywords - SELECT DISTINCT field... and SELECT COUNT(DISTINCT field) ... However in one of web applications that I administer I've noticed performance issues on queries like SELECT DISTINCT(field1), field2, field3 ... DISTINCT() on a single column makes no sense and I am almost sure it is interpreted as SELECT DISTINCT field1, field2, field3 ... but how can I prove this? I've searched mysql site for a reference on this particular syntax but could not find any. Does anyone have a link to definition of DISTINCT() in mysql or knows about other authoritative source on this? Best

  • INSERT INTO ... SELECT FROM ... ON DUPLICATE KEY UPDATE

    - by dnagirl
    I'm doing an insert query where most of many columns would need to be updated to the new values if a unique key already existed. It goes something like this: INSERT INTO lee(exp_id, created_by, location, animal, starttime, endtime, entct, inact, inadur, inadist, smlct, smldur, smldist, larct, lardur, lardist, emptyct, emptydur) SELECT id, uid, t.location, t.animal, t.starttime, t.endtime, t.entct, t.inact, t.inadur, t.inadist, t.smlct, t.smldur, t.smldist, t.larct, t.lardur, t.lardist, t.emptyct, t.emptydur FROM tmp t WHERE uid=x ON DUPLICATE KEY UPDATE ...; //update all fields to values from SELECT, except for exp_id, created_by, location, animal, starttime, endtime I'm not sure what the syntax for the UPDATE clause should be. How do I refer to the current row from the SELECT clause?

  • When should I use static methods in a class and what are the benefits?

    - by NAVEED
    I have concept of static variables but what are the benefits of static methods in a class. I have worked on some projects but I did not make a method static. Whenever I need to call a method of a class, I create an object of that class and call the desired method. Static variable in a method holds it's value even when method is executed but accessible only in its containing method but what is the best definition of static method? Is calling the static method without creating object of that class is the only benefit of static method? What is the accessible range for static method? What is the syntax to create and calling static method in php? Thanks

  • How do I return the entire set / array using NSPredicate?

    - by Prairiedogg
    I'm building a carArray and want to filter the contents conditionally, using an NSPredicate, like so: NSPredicate *pred; switch (carType) { case FreeCar: pred = [NSPredicate predicateWithFormat:@"premium = NO"]; break; case PremiumCar: pred = [NSPredicate predicateWithFormat:@"premium = YES"]; break; default: pred = [NSPredicate predicateWithFormat:@"SOME PREDICATE THAT RETURNS EVERYTHING"]; break; } self.carArray = [aCarArrayIGotFromSomewhere filteredArrayUsingPredicate:pred]; My question is, what is the correct syntax for the value I've stubbed in as SOME PREDICATE THAT RETURNS EVERYTHING which returns all of the instances in the array / set? PS - I know the answer and will post it immediately, just sharing it for everyone's reference as an earlier search on SO did not yield the result.

  • SQL Access INSERT INTO Autonumber Field

    - by KrazyKash
    I'm trying to make a visual basic application which is connected to a Microsoft Access Database using OLEDB. Inside my database I have a user table with the following layout ID - Autonumber Username - Text Password - Text Email - Text To insert data into the table I use the following query INSERT INTO Users (Username, Password, Email) VALUES ('004606', 'Password', '[email protected]') However I seem to get an error with this statement and according to VB it's a syntax error. But then I tried to use the following query INSERT INTO Users (Username) Values ('004606') This query seemed to work absolutely fine... So the problem is I can insert into just one field but not all 3 (excluding the ID field because it's an autonumber). Any help would be appreciated, Thanks

  • Assigning an @Annotation enum a value

    - by h2g2java
    I created enum Restrictions{ none, enumeration, fractionDigits, length, maxExclusive, maxInclusive, maxLength, minExclusive, minInclusive, minLength, pattern, totalDigits, whiteSpace; public Restrictions setValue(int value){ this.value = value; return this; } public int value; } So that I could happily do something like this, which is perfectly legal syntax. Restrictions r1 = Restrictions.maxLength.setValue(64); The reason being is, I am using enum to restrict the type of restriction that could be used, and be able to assign a value to that restriction. However, my actual motivation is to use that restriction in an @annotation. @Retention(RetentionPolicy.RUNTIME) @Target({ElementType.TYPE, ElementType.FIELD, ElementType.METHOD}) public @interface Presentable { Restrictions[] restrictions() default Restrictions.none; } So that, I intended to do this: @Presentable(restrictions=Restrictions.maxLength.setValue(64)) public String userName; to which, the compiler croaks The value for annotation enum attribute must be an enum constant expression. Is there a way to accomplish what I wish to accomplish
