  • ASP.NET HTTPHandler not throwing exception when one is expected

    - by josephj1989
    I have an HttpHandler class (implements IHttphandler) where the path defined for the handler in web.config is *.jpg. I am requesting a Jpg image in my page. Within the HTTP Handler I am writing to a file in the filesystem. By mistake I was trying to write to a non existant directory. This should have thrown an exception but the execution simply proceeds.Ofcourse no file is written. But if I give a proper directory the file is written correctly.Is there anything special about HttpHandler Exceptions. See part of the code public void ProcessRequest(HttpContext context){ File.WriteAllLines(context.Request.ApplicationPath+@"\"+"resul.log",new string[]{"Entered JPG Handler"}); If I put a breakpoint on the File.WriteAllLines statement and then step over it I can see an exception occurring.

  • Cake PHP Routing issue

    - by Smickie
    Hi, I need to do some special routing in cake, but can't for the life of me figure it out. I have a shop controller at /shop, the format of the url will be: /shop/:category/:sub_category/:product_slug In the routing I need to send each part of the url to a different action, for example if the url was just /shop/cakes it would go to the category action of shop. However if the url was /shop/cakes/macaroons or /shop/cakes/fairy it would go to the sub category action on the shop controller. And the the same again for /shop/cakes/macaroons/pistachio would go to the product action on the shop controller. How would I go about this in the routing? Something starting with Router::connect('/shop/:category/:sub_category/:product_slug' ... Or am I way off the mark? Thanks.

  • Questions about linux root file system.

    - by smwikipedia
    I read the manual page of the "mount" command, at it reads as below: All files accessible in a Unix system are arranged in one big tree, the file hierarchy, rooted at /. These files can be spread out over several devices. The mount command serves to attach the file system found on some device to the big file tree. My questions are: Where is this "big tree" located? Suppose I have 2 disks, if I mount them onto some point in the "big tree", does linux place some "special marks" in the mount point to indicate that these 2 "mount directories" are indeed seperate disks?

  • Seam page navigation with includes

    - by Marc
    Hello, I'm using seam page navigation rules. and did not experience any problem with adding rules which redirect from one page to another. But since I designed my page views using those redirection simply don't happen anymore for those pages. Tried to define the rule to the view that gets included, then to the view that includes the others (which to me was making more sense) but none work. Is there anything special about page navigation in seam using included view-id ? I'm using jsf, xhtml as my page views. Thanks

  • Modify 3rd party code in subversion

    - by Alex
    I use a script for my homepage but I'd like to localize it. Furthermore the CSS uses images from a special folder which does not fit to my folder hierarchy. Because I don't want to adopt these paths and settings I'll have to modify the original sources. Currently my repository looks like this: /3rdParty /CompanyA /CompanyAProduct1 /v1_0 /v1_1 /MyProductA /branches /tags /trunk /import /export /source Via svn:externals I map all stuff I need (lib, dll, or code) into the import folder. Now I'd like to modify the files in the import folder but this will modify the original sources, too (as far as I know). What is the best solution to have the modified version in my import folder but the original sources remain unaffected? Should I make a branch of the 3rd party code? But then I have to update the original sources for every new release. Thanks!

  • .Net Logger (Write your own vs log4net/enterprise logger/nlog etc.)

    - by Jack
    I work for an IT department with about 50+ developers. It used to be about 100+ developers but was cut because of the recession. When our department was bigger there was an ambitious effort made to set up a special architecture group. One thing this group decided to do was create our own internal logger. They thought it was such a simple task that we could spend recources and do it ourselves. Now we are having issues with performance and difficulty viewing the logs generated and some employees are frustrated that we are spending recources on infrastructure stuff like this instead of focusing on serving our business and using stuff that already exists like log4net or Enterprise Logger. Can you assist me in listing up reasons why you should not create your own .net logger. Also reasons for why you should are welcome to get a fair point of view :)

  • Path element of Siverlight issue

    - by George2
    Hello everyone, Suppose I have the following XAML code, my confusions are, (1) I do not know the exact meaning of Data attribute, especially items starts with letter M/C, (2) there is no special configuration for TransformGroup (all using default settings), why put the TransformGroup here? <Path Height="2.75" Width="2.75" Data="M2.75,1.375 C2.75,2.1343915 2.1343915,2.75 1.375,2.75 C0.61560845,2.75 0,2.1343915 0,1.375 C0,0.61560845 0.61560845,0 1.375,0 C2.1343915,0 2.75,0.61560845 2.75,1.375 z" Fill="#FF9F9B9B" Stretch="Fill" Stroke="#FF000000" StrokeThickness="0" Canvas.Top="7" x:Name="p3"> <Path.RenderTransform> <TransformGroup> <ScaleTransform/> <SkewTransform/> <RotateTransform/> <TranslateTransform/> </TransformGroup> </Path.RenderTransform> </Path> thanks in advance, George

  • Printing array with delimiters in Perl

    - by Mark B
    I have an array in Perl I want to print with space delimiters between each element, except every 10th element which should be newline delimited. There aren't any spaces in the elements if that matters. I've written a function to do it with for and a counter, but I wondered if there's a better/shorter/canonical Perl way, perhaps a special join syntax or similar. My function to illustrate: sub PrintArrayWithNewlines { my $counter = 0; my $newlineIndex = shift @_; foreach my $item (@_) { ++$counter; print "$item"; if($counter == $newlineIndex) { $counter = 0; print "\n"; } else { print " "; } } }

  • Ideal Java library for cleaning html, and escaping malformed fragments

    - by Tyler
    I've got some HTML files that need to be parsed and cleaned, and they occasionally have content with special characters like <, , ", etc. which have not been properly escaped. I have tried running the files through jTidy, but the best I can get it to do is just omit the content it sees as malformed html. Is there a different library that will just escape the malformed fragments instead of omitting them? If not, any recommendations on what library would be easiest to modify? Clarification: Sample input: <p> blah blah <M+1> blah </p> Desired output: <p> blah blah &lt;M+1&gt; blah </p>

  • UI Components for Windows Mobile Applications (.NET Compact Framework)

    - by splattne
    Applications which run on mobile devices have special user interface requirements. I think Apple did a great job introducing innovative controls on the iPhone/iPod touch platform. Now, I have to design an application for the Windows Mobile platform using the .NET Compact Framework (Visual Studio 2008). I wonder if there are some commercial or open source UI control sets available which are similar to the iPhone / iPod touch UI elements: Scrolling panels based on gestures Instead of a dropdownlist: a new panel with a large list of items Sliding panels etc. I couldn't find any useful products/code. Maybe there is somebody out there with more experience who could help.

  • Can backslash be encoded correctly in URL with URL rewrite?

    - by Millionbonus
    I am working on a ASP.NET MVC2 project. The problem is when a string which would be rewritten into URL that contains special character such as backslash or question mark. That will make URL wrong, even I have encoded it before. For example: 1. I have a product id "p001/2-2". 2. I encoded it into "p001%252f2-2" 3. The URL http://domain.com/ProductView/p001%252f2-2 will response HTTP Error 400 - Bad Request. How can I get it correct?

  • add Constraint on database with trigger

    - by Am1rr3zA
    Hi, I have 3 tables (Student, Course, student_course_choose(have field grade)) I defined a view on these 3 tables that get me an Average of the each student. I want to have constraint(with trigger) on these view(or on the table that need it) to limit the average of each student between 13 and 18. I somewhere read that I must use foreach statement(instead of foreach row) on trigger because when I decrease some grade of special student and his/her average become less than 13 they don't give me error (because later I increase grade of another his/her course ). how must I wrote this Trigger? (I want to implement aprh for testing trigger) note:I can write it in SQL server, oracle or Mysql no diff for me.

  • How can I create "glass" effect on my own UIViews?

    - by lindes
    Hi there, I'm working on an iPhone app that has some non-rectangular UI elements. Currently, I'm subclassing UIView, and in drawRect I'm using a CGPathRef to draw black border and a color-filled interior. I'd like to make these items look more like "buttons", though, so I'd like to have some of the same sort of "glass effects" that are used on e.g. the icons for an iPhone app (when you don't set UIPrerenderedIcon to true), or in other buttons. I hunted around, and found this, which seems to be close to what I need: http://stackoverflow.com/questions/422066/gradients-on-uiview-and-uilabels-on-iphone But I'm having difficulty figuring out how to clip the gradient to my shape. It seems like the mask property on the view would be the right place to go, which seems like it would call for me to create a new CALayer object, with the clipping somehow applied to it. I'm hoping there's some nice convenience function for doing this, though if I need to write something more complicated, that's OK, too. I'm just having difficulty figuring out how to apply the path as a mask. I'm unsure if I need to create a new drawing context and draw the path into it? And then use CGContextClip? I think I've got a lot of the right pieces figured out, I'm just having difficulty understanding how to assemble them. Could someone please point me in the right direction? (I'm happy to read more in the docs, just point me in the right direction, please.)

  • Php PEAR, Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a special-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: 1.) Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? 2.) Can PEAR interface with the MySqli prepared statements I currently use? 3.) Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) 4.) Will it slow down my site once I have a significantly large member base?

  • Wireless barcode scanner

    - by Zinx
    Hi All, I have 2 wireless barcode scanners. I have created an application in C# which reads a barcode and sends data to a web service which then manipulates the data and do further processing. When I start aplication, it first tries to connect to web service and will proceed further only if connection succeded. The problem I am facing is, if I deploy the application through visual studio then it works fine and connects to web service. But if I just copy the contents (exe and config files) manually, then it gives error that unknown host name. Can someone please help me to understand how this connection works? Does it needs some special settings in scanner device which visual studio does automatically while deployment? Thanks and Cheers.

  • What is IPKVM and why would I need that to install SQL Server on my Web Server?

    - by Eric
    Hello. I have a dedicated server, and will be installing SQL Server. However, my hosting company said they can connect an external CD ROM drive and give me KVM over IP to install SQL Server. My question is, what is IPKVM, and how does it work? Do I need special hardware or software on my side to use it....or do I just connect via remote desktop? Also, why can't I remote into my server through remote desktop instead of using KVM over IP?

  • Regular expression to validate name in .NET multilingual web application

    - by BT

Solution: I'm using this regular expression ^\p{L}[\p{L}\p{Pd}\x27]*\p{L}$ , and the below MSISDN article was very helpful: MSDN - Regular Expression Also below tool is very helpful, in validating your regular expression: Regex Builder

  • What's the reason both Image and Bitmap classes don't implement a custom equality/hashcode logic?

    - by devoured elysium
    From MSDN documentation, it seems as both GetHashCode() and Equals() haven't been overriden in Bitmap. Neither have them been overriden in Image. So both classes are using the Object's version of them just compares references. I wasn't too convinced so I decided to fire up Reflector to check it out. It seems MSDN is correct in that matter. So, is there any special reason why MS guys wouldn't implement "comparison logic", at least for the Bitmap class? I find it is kinda acceptable for Image, as it is an abstract class, but not so much for the Bitmap class. I can see in a lot of situations calculating the hash code can be an expensive operation, but it'd be alright if it used some kind of lazy evaluation (storing the computed hash code integer in a variable a variable, so it wouldn't have to calculate it later again). When wanting to compare 2 bitmaps, will I have to resort to having to run all over the picture comparing each one of its pixels? Thanks

  • Statement hierarchy in programming languages

    - by sudo
    I quickly wrote an interpreter for some sort of experimental programing language i came up with, in PHP (yes, in PHP). The language itself doesn't have anything really special, I just wanted to give it a try. I got the basic things working (Hello World, input to output, string manipulation, arithmetics) but I'm getting stuck with the management of blocks and grouped statements. What I mean is: PHP and most other languages let you do this: ((2+2)*(8+2)+2), of course not only with mathematical computations. My program structure currently consists of a multidimensional array built like this: ID => Type (Identifier, String, Int, Newline, EOF, Comma, ...) Contents (If identifier, int or string) How could I allow statements to be executed in a defined order like in the PHP example above?

  • Which build tool to teach?

    - by Helper Method
    While similiar questions have been asked, this one's focused on which is best/easiest to teach. I'm giving a weekly tutorial at my university focusing on data structures and algorithms. Fromn time to time I introduce tools which may prove helpful in future projects like JUnit, Mercurial, Eclipse etc.. I plan to show them some kind of build tool but I'm not sure which one to choose. I by myself have very little knowledge about build tools, except a little experience in using make. It's more the concept of a build tool I want to show them, not a special tool per se. Which would be the most easiest/future proof/whatever tool to show them? I've read a little bit about Gradle, which looks nice, but so far I think Ant could be a good choice (it's a Java course I'm giving).

  • In Ruby, can the coerce() method know what operator it is that requires the help to coerce?

    - by Jian Lin
    In Ruby, it seems that a lot of coerce() help can be done by def coerce(something) [self, something] end that's is, when 3 + rational is needed, Fixnum 3 doesn't know how to handle adding a Rational, so it asks Rational#coerce for help by calling rational.coerce(3), and this coerce instance method will tell the caller: # I know how to handle rational + something, so I will return you the following: [self, something] # so that now you can invoke + on me, and I will deal with Fixnum to get an answer So what if most operators can use this method, but not when it is (a - b) != (b - a) situation? Can coerce() know which operator it is, and just handle those special cases, while just using the simple [self, something] to handle all the other cases where (a op b) == (b op a) ? (op is the operator).

  • Does Displaytag stash the "media type" in a page or request attribute?

    - by Pointy
    When you enable "export" from Displaytag, the tag code gives you links with special magic parameters that the tag recognizes as indicators that the table contents should be exported (as CSV, Excel, whatever). Well I'm interested in detecting the media type so that (for example) I can exclude columns that make no sense in an export (embedded action buttons, for one thing, or checkboxes for row selection). I suppose I could write a table decorator and use that to stick the media type on the request, but it'd be nice to avoid that if the tag already does it. The documentation is not clear on the subject; I guess I can start digging through the source code too.

  • Custom Date Format with jax-rs in apache cxf?

    - by Oscar Chan
    Hi, I have been googling to figure out how I can customize the Date format when I use jax-rs on apache CXF. I looked at the codes, and it seems that it only support primitives, enum and a special hack that assume the type associated with @ForumParam has a constructor with a single string parameter. This force me to use String instead of Date if I want to use ForumParam. it is kind of ugly. Is there a better way to do it? @POST @Path("/xxx") public String addPackage(@FormParam("startDate") Date startDate) { ... } Thanks

  • Drupal 7: cancel user registration if a wrong field value has been submitted.

    - by Alexander Farber
    Hello, I have a Drupal 7 with 1 field added to registration form - a List with possible values Robot / Male / Female: # select * from field_data_field_gender; entity_type | bundle | deleted | entity_id | revision_id | language | delta | field_gender_value -------------+--------+---------+-----------+-------------+----------+-------+-------------------- user | user | 0 | 6 | 6 | und | 0 | Male user | user | 0 | 5 | 5 | und | 0 | Male user | user | 0 | 7 | 7 | und | 0 | Female user | user | 0 | 1 | 1 | und | 0 | Male The first value Robot is a default value - to prevent SPAM robots from registering at my site. Is there a way to cancel user registration, when a new user submits the registration web form with the default Robot value? (i.e. only Male and Female values are allowed). I've looked at the core Trigger module, but don't see anything suitable there. I've looked at the hook_user_presave and hook_user_insert API docs, but don't see a way there to cancel an ongoing user registration. (I was expecting to do that by returning a special value from those methods...) Thank you! Alex

  • Representing geographical points/polygons in Python/Django

    - by Cornflake
    I'm building a website in Django, and I want one of my datatypes to be a geographical polygon. I want to mark points on a map (say, in Google Maps) and then store the resulting polygon in the database. Is there any way to do it that will save me the work of typing all the longitudes and latitudes manually? I guess I'm looking both for a geographical library for Python, and for a special website that will let me mark points on the map and save them in a standard format. Thanks!
