  • C# Language Design: explicit interface implementation of an event

    - by ControlFlow
    Small question about C# language design :)) If I had an interface like this: interface IFoo { int Value { get; set; } } It's possible to explicitly implement such interface using C# 3.0 auto-implemented properties: sealed class Foo : IFoo { int IFoo.Value { get; set; } } But if I had an event in the interface: interface IFoo { event EventHandler Event; } And trying to explicitly implement it using field-like event: sealed class Foo : IFoo { event EventHandler IFoo.Event; } I will get the following compiler error: error CS0071: An explicit interface implementation of an event must use event accessor syntax I think that field-like events is the some kind of dualism for auto-implemented properties. So my question is: what is the design reason for such restriction done?

  • iphone sdk conditional in switch function

    - by Oliver
    I'm trying to make a random image appear on the press of a button. So it generates a random number, and the switch algorithm swaps the chosen image with the one in the imgview. but I want a switch in the settings app to toggle which set of images to use. I know pretty much how to do it...it's just that it doesn't work. I'm missing some syntax thing...Please help, stackoverflow? it's my birthday. int Number = rand() %30; NSString *toggleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"]; switch (Number) { if (*toggleValue == 0) { case 0: picture.image = [UIImage imageNamed:@"1.png"]; break; case 1: picture.image = [UIImage imageNamed:@"2.png"]; break;} else { case 0: picture.image = [UIImage imageNamed:@"3.png"]; break; case 1: picture.image = [UIImage imageNamed:@"4.png"]; break;} }

  • How do I do client-side validation in WPF using WCF RIA Services

    - by lsb
    Hi! I've created a WCF RIA Service that I'd like to use with a WPF application. I've added several System.ComponentModel.DataAnnotations validation rules on the entities meta-data, all which work great on the server when I call .SubmitChanges(changeSet) from the client. I'd also like to validate my entities on the client side before I sumbit my changes to the server but I have no idea how to do so. Any help in this regard would be greatly appreciated! Thanks....

  • resolving localhost in php so can be views outside VM

    - by DA
    I'm running Windows 7. Within, I'm running Virtualbox and Ubuntu. Within Ubuntu, I'm running Apache and using PHP codeigniter. To reference our CSS and JS files, we use this syntax: <?php echo site_url('css/styles.css'); ?> When viewing the site locally (within Ubuntu VM) that resolves to: http://localhost/styles.css So works fine. The catch is when I access that site from within Windows 7 (for IE testing). To access the site in Windows 7, I refer to the IP address of the VM: http://xx.x.x.x/ That loads the site but, alas, all the site_url variables are still being rewritten as 'localhost'. Said files obviously don't exist on the localhost of my windows 7. Is there a way around this short of just hard-coding relative links in my PHP file?

  • Difference between piping a file to sh and calling a shell file

    - by Peter Coulton
    This is what was trying to do: $ wget -qO- www.example.com/script.sh | sh which quietly downloads the script and prints it to stdout which is then piped to sh. This unfortunately doesn't quite work, failing to wait for user input a various points, aswell as a few syntax errors. This is what actually works: $ wget -qOscript www.example.com/script.sh && chmod +x ./script && ./script But what's the difference? I'm thinking maybe piping the file doesn't execute the file, but rather executes each line individually, but I'm new to this kind of thing so I don't know.

  • Add HTMl to CCK within Drupal

    - by Romelus96
    Hello im a newbie at using Drupal, and have come across a block in my progress. I have been using CCK to add new content types to my forms. I was wondering if there was any way to add to the form that is generated so that i may contain the elements and also insert visual html code like head rules etc. I have dabbled with the hook_form_alter() and it does not seem to help me in my efforts. Ive been through adjusting tpl.php files and such and have made no progress. Please if there is any one there in the inter-webs who is knowledgeable on this matter your advice would be greatly appreciated. Here is just an example of what I would want to do within the form: 1. Contain field elements within DIV's 2. Add HTML Content into the form

  • Dynamic typed language example using ANTLR

    - by wvd
    Hey all, I'm looking for some ANTLR examples, I tried googling a bit but I found certain things which didn't fit my requirments. I found the Mantra project, but it's statically typed and is 'too' big for me at this moment, then I found 'pie' as interpreter, which is dynamically typed, which what I want, but it uses a syntax-directed interpreter. I'm looking for a pretty small language which is dynamically typed and uses AST's if possible. It doesn't need to be advanced, if it would have classes I would already be very happy. Thanks, William van Doorn

  • Author in wiki, generate PDF documents, CHM files or embedded help

    - by Dilum Ranatunga
    Anyone know of a wiki or wiki plugin that generates a PDF file or CHM file that spans the entire wiki? I would like to have control of the table of contents. I would like the internal and external links to work. Ideally allow for tweaking the output template, but that is not a deal-breaker. I want to generate content using WIKI syntax and mindset (lots of cross-links etc), but ship the content in PDF, CHM or an embedded application form. Something friendlier than installing the wiki software on the enduser machine...

  • Is there a config option in PHP to prevent undefined constants from being interpreted as strings?

    - by mrbinky3000
    This is from the php manual: http://us.php.net/manual/en/language.constants.syntax.php If you use an undefined constant, PHP assumes that you mean the name of the constant itself, just as if you called it as a string (CONSTANT vs "CONSTANT"). An error of level E_NOTICE will be issued when this happens. I really don't like this behavior. If I have failed to define a required constant, I would rather the script fail so that I am forced define it. Is there any way to force PHP to crash the script if it tries to use an undefined constant? For example. Both of these scripts do the same thing. <?php define('DEBUG',1); if (DEBUG) echo('Yo!'); ?> and <?php if(DEBUG) echo('Yo!'); ?> I would rather the second script DIE and declare that it tried to use an undefined constant DEBUG.

  • Am I immoral for using a variable name that differs from its type only by case?

    - by Jason Baker
    For instance, take this piece of code: var person = new Person(); or for you Pythonistas: person = Person() I'm told constantly how bad this is, but have yet to see an example of the immorality of these two lines of code. To me, person is a Person and trying to give it another name is a waste of time. I suppose in the days before syntax highlighting, this would have been a big deal. But these days, it's pretty easy to tell a type name apart from a variable name. Heck, it's even easy to see the difference here on SO. Or is there something I'm missing? If so, it would be helpful if you could provide an example of code that causes problems.

  • jQuery Delay Question

    - by Fuego DeBassi
    <script type="text/javascript"> $(document).ready(function() { $(".module .caption").hide(); $(".module").hover(function() { $(this).find(".caption").slideDown().end().siblings('.module').addClass('under'); },function() { $(this).find(".caption").slideUp().end().siblings('.module').removeClass('under').delay(10000); }); }); </script> This works great, except the .delay doesn't work, is my syntax wrong? I'm just trying to accomplish haveing the .removeClass("under") delayed by a second or two when the mouse un-hovers. I don't want to delay the slideUp. Any ideas?

  • 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?

  • Creating Instance of a DataContract Class on the client side

    - by hgulyan
    I'm not sure, if it's right to do this, but I'd like to ask this question again ( http://stackoverflow.com/questions/2498644/creating-instance-of-a-service-side-datacontract-class-on-client-side-in-wcf ). The main question is - why there's difference between creating instance on the client side and creating it on the server side? Why there're some properties, that lose their values when you create them on the client side and pass it to service's functions? What could be the issue? Any version will be appreciated. I've written about my problem in the update part of the question in that link. Thank You. p.s. If this is against the rules, I'll delete it.

  • Should you remove all warnings in your Verilog or VHDL design? Wh or why not?

    - by Brian Carlton
    In (regular) software I have worked at companies where the gcc option -Wall is used to show all warnings. Then they need to be dealt with. With non-trivial FPGA/ASIC design in Verilog or VHDL there are often many many warnings. Should I worry about all of them? Do you have any specific techniques to suggest? My flow is mainly for FPGAs (Altera and Xilinx in particular), but I assume the same rules would apply to ASIC design, possibly more so due to the inability to change the design after it is built.

  • Why WCAG made 3 level "A", "AA" and "AAA"?

    - by jitendra
    What is the purpose of making 3 priority level by WCAG? is it like? If client not paying extra or if we don't have much time then go for A If client paying then or if we have time to make site compatible go for at least AA If client paying and needed according to govt. rules then go for AAA If we are making site then which level we should we try to achieve, or we should do only on client request? Although i found these definitions on this site but these are confusing for me • Priority 1: For all users to access the Web content and for Web developers to attain Conformance level “A”, these requirements must be satisfied. • Priority 2: These requirements should be satisfied by the Web developers so that no group finds it difficult to access the Web content and so as to attain Conformance level “AA”. • Priority 3: These requirements may be satisfied by the Web developers to facilitate access to Web content for some groups and attain Conformance level “AAA”.

  • SQL Having Clause

    - by Wally
    I'm trying to get a stored procedure to work using the following syntax: select count(sl.Item_Number) as NumOccurrences from spv3SalesDocument as sd left outer join spv3saleslineitem as sl on sd.Sales_Doc_Type = sl.Sales_Doc_Type and sd.Sales_Doc_Num = sl.Sales_Doc_Num where sd.Sales_Doc_Type='ORDER' and sd.Sales_Doc_Num='OREQP0000170' and sl.Item_Number = 'MCN-USF' group by sl.Item_Number having count (distinct sl.Item_Number) = 0 In this particular case when the criteria is not met the query returns no records and the 'count' is just blank. I need a 0 returned so that I can apply a condition instead of just nothing. I'm guessing it is a fairly simple fix but beyond my simple brain capacity. Any help is greatly appreciated. Wally

    - by Arthur Ulfeldt
    I needed to add AM_PATH_CHECK to configure.am I then try to run the usual sequence of autotools commands to rebuild all the makefiles and whatnot: aclocal automake -ac autoheader autoreconf ./configure make and here my lack of understanding of autotools showes up because this release of openssh has no Makefile.am??? now what do I do? if i try to ignore this and build anyway configure dies with this lovely error: checking whether OpenSSL's PRNG is internally seeded... yes ./configure: line 18275: syntax error near unexpected token `PROG_LS,' ./configure: line 18275: `OSSH_PATH_ENTROPY_PROG(PROG_LS, ls)' caused by this line in configure.ac: OSSH_PATH_ENTROPY_PROG(PROG_LS, ls) Is this actually caused by my changes to configure.ac? what can I do to regenerate the required files to allow configure to work? if i take my changes out and dont run aclocal then it works???

  • Git pre-receive hook

    - by Ralphz
    Hi When you enable pre-receive hook for git repository: It takes no arguments, but for each ref to be updated it receives on standard input a line of the format: < old-value SP < new-value SP < ref-name LF where < old-value is the old object name stored in the ref, < new-value is the new object name to be stored in the ref and is the full name of the ref. When creating a new ref, < old-value is 40 0. Does anyone can explain me how do I examine all the files that will be changed in the repository if i allow this commit? I'd like to run that files through some scripts to check syntax and so on. Thanks.

  • problem with sql job and datetime parameter

    - by geoff swartz
    Another developer created a stored procedure that is set up to run as a sql job each month. It takes one parameter of datetime. When I try to invoke it in the job or in just a query window I get an error "Incorrect syntax near ')'" The call to execute it is... exec CreateHeardOfUsRecord getdate() When I give it a hard coded date like exec CreateHeardOfUsRecord '4/1/2010' it works fine. Any idea why I can't use getdate() in this context? Thanks.

  • Correct sequence of actions when using Markdown & MySQL?

    - by Andrew Heath
    I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

  • Drop a DB2 view if it exists...

    - by grenade
    Why doesn't this work in IBM Data Studio (Eclipse): IF EXISTS (SELECT 1 FROM SYSIBM.SYSVIEWS WHERE NAME = 'MYVIEW' AND CREATOR = 'MYSCHEMA') THEN DROP VIEW MYSCHEMA.MYVIEW; END IF; I have a feeling it has to do with statement terminators (;) but I can't find a syntax that works. Another similar question at http://stackoverflow.com/questions/355687/how-to-check-a-procedure-view-table-exists-or-not-before-dropping-it-in-db2-9-1 suggests that they had to create a proc but this isn't a solution for us.

  • PDF writeHTML for rendering tables

    - by sami
    I'm using TCPDF and following this example which uses writeHTML and heredoc syntax to write a table. http://www.tcpdf.org/examples/example_048.phps I'm trying to do though is switch the font using setFont before writing each column. This means I have to break the html and write it on different pieces (see pseudo code). But once I break the HTML like that, it doesn't work, I think because it becomes invalid. writeHTML <tr> writeHTML first column setFont() writeHTML second column writeHTML </tr> I want to use writeHTML because it helps me write the table without having to manually construct. But how can I make modifications before I output each cell?
