  • code optimization; switch versus if's

    - by KaiserJohaan
    Hello, I have a question about whether to use 'case' or 'ifs' in a function that gets called quite alot. Here's the following as it is now, in 'ifs'; the code is self-explanatory: int identifyMsg(char* textbuff) { if (!strcmp(textbuff,"text")) { return 1; } if (!strcmp(textbuff,"name")) { return 2; } if (!strcmp(textbuff,"list")) { return 3; } if (!strcmp(textbuff,"remv")) { return 4; } if (!strcmp(textbuff,"ipad")) { return 5; } if (!strcmp(textbuff,"iprm")) { return 6; } return 0; } My question is: Would a switch perform better? I know if using ifs, I can place the most likely options at the top.

  • AJAX Beginner: If then statement

    - by dassouki
    In menu.html, I have my menu items(a href links), let's call them, menu_1, menu_2, .... In map.js displays the contents of a map, it calls an API to display some layers and maps. I have a lot of maps to show but i only want to call the api once. Using AJAX, I was wondering if it's possible to have an if/then or select/case in my js, so that if menu_1 is clicked, then implement map_1 etc. without having the page to reload. The only way I thought I could do this is using Post/get .. so when you click on menu_1 it takes you to page.php?page_id=1 . JS will read that and display the map. I'm new to JS and AJAX so please feel free to butcher me

  • best analogy to explain free software floss to non geeks

    - by opensas
    How do you explain free libre open source software to a computer illiterate guy? Two well known analogies I've often heard are: free software as a meal recipe, a set of instructions for you to inspect, learn, put into practice, and improve... versus a canned meal that you can only swallow without even knowing what you're eating... and the other is comparing privative software to a car that you aren't allowed to open it's trunk to see inside in case anything goes wrong... I'd like to know what other analogies you know that might help us explain free software to non geeks saludos sas

  • How to change page author in wordpress?

    - by GaVrA
    Ofc i know how to do that, but the thing is that i am using "User Role Editor" and i have one user group that can read and edit published pages. Now, i will be adding all the pages on that site, and we will have several users that will need to have only one page they can edit, so i need for that page to change "Page author" to that user. In case you didnt know, when user have "Edit published pages" enabled they can edit only pages where they are listed as author. Problem is i can only do that by going in phpmyadmin and changing the page_author field to the id of that user because that user group, like i said, can only read and edit published pages. That is why i can not change page author from "Edit page" page to user from that user group. So my question is: does anyone know any solution to this problem which does not involve me going to phpmyadmin and changing the id for page_author there?

  • Should I commit or rollback a transaction that creates a temp table, reads, then deletes it?

    - by Triynko
    To select information related to a list of hundreds of IDs... rather than make a huge select statement, I create temp table, insert the ids into it, join it with a table to select the rows matching the IDs, then delete the temp table. So this is essentially a read operation, with no permanent changes made to any persistent database tables. I do this in a transaction, to ensure the temp table is deleted when I'm finished. My question is... what happens when I commit such a transaction vs. let it roll it back? Performance-wise... does the DB engine have to do more work to roll back the transaction vs committing it? Is there even a difference since the only modifications are done to a temp table? Related question here, but doesn't answer my specific case involving temp tables: http://stackoverflow.com/questions/309834/should-i-commit-or-rollback-a-read-transaction

  • Creating an SQL Compact file: Template or script?

    - by David Veeneman
    I am writing an application that writes to SQL Compact files that have a specific schema, and I am now implementing the New File use case. The simplest approach seems to be to use a Template pattern: first, create a template file that lives in the application directory. Then, when the user selects New File, the template is copied to the name and destination specified by the user in a New File dialog. The alternative is a scripted approach: Use the same New File dialog, but dispense with the template file. Instead, create an empty SQL Compact file using the name/destination specified by the user, and then execute a T-SQL script on it from managed code. At this point, I am leaning toward the Template approach, because it is simpler. Is there any reason I should not use that approach? Thanks for your help.

  • JavaFX Threading issue - GUI freezing while method call ran.

    - by David Meadows
    Hi everyone, I hoped someone might be able to help as I'm a little stumped. I have a javafx class which runs a user interface, which includes a button to read some text out loud. When you press it, it invokes a Java object which uses the FreeTTS java speech synth to read out loud a String, which all works fine. The problem is, when the speech is being read out, the program stops completely until its completed. I'm not an expert on threaded applications, but I understand that usually if I extend the Thread class, and provided my implementation of the speech synth code inside an overridden run method, when I call start on the class it "should" create a new Thread, and run this code there, allowing the main thread which has the JavaFX GUI on to continue as normal. Any idea why this isn't the case? Thanks a lot in advance!

  • Move constructor and assignment operator: why no default for derived classes?

    - by doublep
    Why there is default move constructor or assignment operator not created for derived classes? To demonstrate what I mean; having this setup code: #include <utility> struct A { A () { } A (A&&) { throw 0; } A& operator= (A&&) { throw 0; } }; struct B : A { }; either of the following lines throws: A x (std::move (A ()); A x; x = A (); but neither of the following does: B x (std::move (B ()); B x; x = B (); In case it matters, I tested with GCC 4.4.

  • Oracle XE as local recovery database and Oracle Standard as main db

    - by jbendahan
    Hi, I just wanted to know what you guys think about this. I have an app written in Visual Basic .Net as my front end and and Oracle 11g Standart database as the back-end. So I have like 20 pc's running this app locally. They're all inserting, updating, deleting data on this single database. I want to develop a solution in the case that the server database crashes or cannot stay on line. So i think of having oracle 10g XE on each pc. Thus all the data will be stored in the local db. I think about running a proccess once in a while (ex. every 15 minutes) to send/get the data to/from the main server. What do you think about this strategy?

  • Web Setup Project - Getting the Current Machine Name

    - by Shane Kenney
    I've got a web setup project with a custom screen in it that asks for a machine name. Is there anyway to prepopulate this field with the current machines name? For the case that I need it for just including "Localhost" does not meet my requirements. "Environment.MachineName" will return the machine name within a code block which would be fine if I was needing it in a custom action. But it seems custom actions don't excecute until after you go through the installation wizard... So I cant actually use it. Anyway let me know what you think.

  • JS Url GET vars - problem with encoding

    - by Martin
    Hey there! I'm having a bit of trouble here and I was hoping someone throws me a hint :) I'm getting some GET VARS with JS but I have trouble with non-latin charsets: cyrillic for example. The cyrillic var appears correct in the url but when I retrieve it with JS I get some dummy string. I was wondering of a function similar to "unescape" for such a case. Alternatively, if someone knows a way I could convert a cyrillic string to the same dummy string I get from the URL, it will still do me the trick, since all I need is compare. :) Thanks! Martin

  • How do I use modulus for float/double?

    - by ShrimpCrackers
    I'm creating an RPN calculator for a school project. I'm having trouble with the modulus operator. Since we're using the double data type, modulus won't work on floating point numbers. For example, 0.5 % 0.3 should return 0.2 but I'm getting a division by zero exception. The instruction says to use fmod(). I've looked everywhere for fmod(), including javadocs but I can't find it. I'm starting to think it's a method I'm going to have to create? edit: hmm, strange. I just plugged in those numbers again and it seems to be working fine...but just in case. Do I need to watch out using the mod operator in Java when using floating types? I know something like this can't be done in C++ (I think).

  • Using CGRectIntersectsRect for collision detection

    - by user309030
    Hi guys, I've got a long rectangular image which is rotated at different kind of angles. However the frame of the rectangular image does not rotate along with the image and instead, the rotation causes the frame to to become larger to fit the rotated image. So when I used CGRectIntersectsRect, the collision detection is totally off because the other image colliding with the rectangular image will collide before it even reaches the visible area of the rect image. In case you don't really know what I'm talking about, have a look at the ascii drawing: normal rectangular image frame, O - pixels, |, – - frame |----------| |OOOOOOOOOO| |----------| after rotation |----------| |O | | O | | O | | O | | O | | O | | O | | O | | O | |----------| I've read through some of the collision articles but all of them are talking about collision with a normal straight rectangle and what I really want is collision with a slanted image, preferably pixel collision detection. TIA for any suggestions made.

  • Self-type mismatch in Scala

    - by Alexey Romanov
    Given this: abstract class ViewPresenterPair { type V <: View type P <: Presenter trait View {self: V => val presenter: P } trait Presenter {self: P => var view: V } } I am trying to define an implementation in this way: case class SensorViewPresenter[T] extends ViewPresenterPair { type V = SensorView[T] type P = SensorPresenter[T] trait SensorView[T] extends View { } class SensorViewImpl[T](val presenter: P) extends SensorView[T] { presenter.view = this } class SensorPresenter[T] extends Presenter { var view: V } } Which gives me the following errors: error: illegal inheritance; self-type SensorViewPresenter.this.SensorView[T] does not conform to SensorViewPresenter.this.View's selftype SensorViewPresenter.this.V trait SensorView[T] extends View { ^ <console>:13: error: type mismatch; found : SensorViewPresenter.this.SensorViewImpl[T] required: SensorViewPresenter.this.V presenter.view = this ^ <console>:16: error: illegal inheritance; self-type SensorViewPresenter.this.SensorPresenter[T] does not conform to SensorViewPresenter.this.Presenter's selftype SensorViewPresenter.this.P class SensorPresenter[T] extends Presenter { ^ I don't understand why. After all, V is just an alias for SensorView[T], and the paths are the same, so how can it not conform?

  • Integrating Fish eye with Jenkins

    - by ramaperumal
    Jenkins is up and running in my organization.In configure tab under Repository browser we have an option called fish eye.If I select fish eye as an repository browser it is asking the fish eye URL (such as http://fisheye6.cenqua.com/browse/ant/)My requirment is I need to fetch the reports such as (we would like to track the SVN to take chain change report, to give statistics on how many check-in happening in each code base, how many cut has been taken from each branches…etc ).We need to achieve all these things in Jenkins itself. For performing such things we need to setup the seperate fish eye server.If that is the case why we have the fish eye option in jenkins.We can perform all these activities in Fisheye instead of Jenkins. Please suggest, Thx Rama

  • Is Eclipse Remote System Explorer broken on Windows?

    - by Kev
    I have the following setup on Windows 7 Ultimate x64: Eclipse Indigo 2.7.2 (Build: M20120208-0800) Remote System Explorer 3.3.2 (see screenshot) (Oracle/Sun) Java 1.6 Update 31 (x86) Despite all my best efforts I am unable to connect to a remote system (a Centos 5.6 server on my local LAN) using a Remote System Explorer SSH connection - I've tried both password authentication and using my SSH private key. Here is a screenshot of both the Eclipse error dialogue and what is logged in my /var/log/secure log file: /var/log/secure: Apr 1 12:00:21 nagios sshd[6176]: Received disconnect from 172.16.3.88: 3: com.jcraft.jsch.JSchException: Auth fail When I connect for the first time I do get prompted to verify the authenticity of the remote host and the RSA key fingerprint. But that's as far as things go. Performing the same operation with the same credentials on my Fedora Core 16 box (also running the same version of Eclipse and Java) to the same server is successful. This leads me to believe that RSE SSH support on Windows is either broken or there's some piece of the SSH-on-Windows puzzle I'm missing. Is this the case?

  • ERD-CLASS design

    - by Mahesh
    Hello guyz,i am new to daatbase and class diagram.I just get scenarios from internet and try to develop ERD and Class Diagram for them.But the following scenario has caused me some problems, and i am not sure about my design. "Whenever an employee fills leave application form, the leave application should be appeared for approval to his/her team leader. Team Leader has the option to change the date of requested leave and to approve or reject the leave. Employee also has the option to change date of previously unapproved leaves or to cancel any of unapproved leave. In case of team leader, he can approve his own leaves. Management should be able to create categories of leaves like (Casual, Sick, Planned work, etc) and should be able to adjust the days allocated to each type of leave". I have identified these as entities for ERD 1) Employee(I think i dont need to make entity for Technical lead,since he is an employee) 2) LeaveHistory 3) LeaveCategory Plz correct me if the system need more classes or entities

  • Recording object method calls to generate automated test.

    - by Constantin
    I have an object with large interface and I would like to record all its method calls done during a user session. Ideally this sequence of calls would be available as source code: myobj.MethodA(42); myobj.MethodB("spam", false); ... I would then convert this code to a test case to have a kind of automated smoke/load test. WCF Load Test can do this for WCF services and CodedUI test recorder can do this for UIs. What are my options for a POCO class? I am in position to edit application code and replace the object in question with some recording/forwarding proxy.

  • Diagonal of polygon is inside or outside?

    - by Himadri
    I have three consecutive points of polygon, say p1,p2,p3. Now I wanted to know whether the orthogonal between p1 and p3 is inside the polygon or outside the polygon. I am doing it by taking three vectors v1,v2 and v3. And the point before the point p1 in polygon say p0. v1 = (p0 - p1) v2 = (p2 - p1) v3 = (p3 - p1) With reference to this question, I am using the method shown in the accepted answer of that question. It is only for counterclockwise. What if my points are clockwise. I am also knowing my whole polygon is clockwise or counterclockwise. And accordingly I select the vectors v1 and v2. But still I am getting some problem. I am showing one case where I am getting problem. This polygon is counterclockwise. and It is starting from the origin of v1 and v2.

  • strerror_r returns trash when I manually set errno during testing

    - by Robert S. Barnes
    During testing I have a mock object which sets errno = ETIMEDOUT; The object I'm testing sees the error and calls strerror_r to get back an error string: if (ret) { if (ret == EAI_SYSTEM) { char err[128]; strerror_r(errno, err, 128); err_string.assign(err); } else { err_string.assign(gai_strerror(ret)); } return ret; } I don't understand why strerror_r is returning trash. I even tried calling strerror_r(ETIMEDOUT, err, 128) directly and still got trash. I must be missing something. It seems I'm getting the gnu version of the function not the posix one, but that shouldn't make any difference in this case.

  • What SQL is being sent from a SqlCommand object

    - by Justin808
    I have a SqlCommand object on my c# based asp.net page. The SQL and the passed parameters are working the majority of the time. I have one case that is not working, I get the following error: String or binary data would be truncated. The statement has been terminated. I understand the error and but all the columns in the database should be long enough to hold everything being sent. My questions, Is there a way to see what the actual SQL being sent to the database is from SqlCommand object? I would like to be able to email the SQL when an error occurs. Thanks, Justin

  • msvsmon is locking up my pdbs

    - by Sam Saffron
    During developement of my media center plugin (which has a few custom build steps to gac stuff and such) msvsmon has a rather annoying behaviour. First compilation usually goes well, but subsequent compilations complain about myplugin.pdb being locked Error 1 Unexpected error creating debug information file 'C:\Users\sam\source\myfile.PDB' -- 'C:\Users\sam\source\obj\Debug\myfile.pdb: The process cannot access the file because it is being used by another process. If I exit VS and nuke the object directory, I am able to compile again. Also, if I kill off msvsmon.exe I am able to compile again (but can not debug) Has anyone seen this error? Are there any workarounds? I already disabled live semantic errors, just in case.

  • Array merging/manipulation with Velocity

    - by Razor
    Hello, I have an array set inside a velocity template that contains some paths. The idea is to put a few "default" .js/.css files that 90% of the pages will use in this array. However, the other pages will still have to be able to add/delete values from this array, in case there are no linked files at all, or I need to add some. Given this code: #set ( $head.scripts = [ "https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js", "https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.0/jquery-ui.min.js" ] ) #foreach ($URI in $head.scripts) <script type="text/javascript" src="$URI"></script> #end is there any way to add/delete values from these defaults? I have seen this list tool, but it looks like it's not enough for what I need.

  • How to debug CSS/Javascript hover issues

    - by Jason Creighton
    I often find myself wanting to debug CSS layout issues that involve DOM changes caused by Javascript in reaction to a hover event or different CSS rules applying due to the :hover selector. Normally, I'd use Firebug to inspect the element that's giving me trouble and see what its CSS properties were, and where those properties come from. However, when hovering is involved, it becomes impossible, because as soon as you move your mouse down to the Firebug panel, the elements you're interested in are no longer hovered, the CSS rules that apply are different, and (in the case of JS hovers) the DOM is changed. Is there any way I can "freeze" the state of the DOM and application of :hover in order to inspect the DOM as it was during a hover event? Any other ideas on how to debug this sort of issue are welcome, of course.

  • Easiest way of checking if a string consists of unique characters?

    - by serg555
    I need to check in Java if a word consists of unique letters (case insensitive). As straight solution is boring, I came up with: For every char in a string check if indexOf(char) == lastIndexOf(char). Add all chars to HashSet and check if set size == string length. Convert a string to a char array, sort it alphabetically, loop through array elements and check if c[i] == c[i+1]. Currently I like #2 the most, seems like the easiest way. Any other interesting solutions?
