  • Unreachable code detected in case statement

    - by alex
    I have a code: protected override bool ProcessCmdKey(ref Message msg, Keys keyData) { switch (keyData) { case Keys.Alt|Keys.D1: if (this._condition1) { return true; } else { return base.ProcessCmdKey(ref msg, keyData); } break; case Keys.Control |Keys.U: if (this._condition2) { return true; } else { return base.ProcessCmdKey(ref msg, keyData); } break; default: return base.ProcessCmdKey(ref msg, keyData); } return true; It gives me "unreachable code detected" warning on breaks. Is it good practice not to use break operator here ? I don't want to turn off "unreachable code detected" warning. PS: There are many case in my ProcessCmdKey method.

  • MySQL enters another value that the one given by PHP

    - by Tristan
    Hello, The big problem : mysql does not stores the information i told him to via PHP Example (this req is an echo just before the query) : INSERT INTO serveur (GSP_nom , IPserv, port, tickrate, membre, nomPays, finContrat, type, jeux, slot, ipClient, email) VALUES ( 'ckras', '88.191.88.57', '37060', '100' , '', 'Allemagne','20110519', '2', '4','99' ,'82.220.201.183','[email protected]'); But on the MySQL i have : 403 ckras 88.191.88.57 32767 100 Allemagne 20110519 1 2010-04-25 00:51:47 2 4 99 82.220.201.183 [email protected] port : 37060 (right value) //// 32767 (MySQL's drug?) Any help would be appreciated, i'm worse than stuck and i'm ** off PS: *There is no trigger on the mysql as far as i know / there is no controll on the port which means that nowhere i modify the "port" value and this script works for 80% of the time ( it seems that as soon as the users enters a port = 30000 it causes that bug), an user first reported to me this error today and the script was running since 3 months* Thanks

  • Why does it not allowed to use try-catch statement without {} ?

    - by alex
    Why can't I use code like this ? 1 int i = 0; try i = int.Parse("qwerty"); catch throw; 2 try i = int.Parse("qwerty"); catch; finally Log.Write("error"); And should write like this 1 int i = 0; try { i = int.Parse("qwerty"); } catch { throw; } 2 try { i = int.Parse("qwerty");} catch {} finally {Log.Write("error");} PS: I can use if-else statement without {}. Why should I use them with try-catch(-finally) statement ? Is there any meaningful reason ? Is it only because that some people think that code is hard to read ? Several months ago I asked that question on russian programming forum but I got no satisfactory answer ...

  • 128bit hash comparison with SSE

    - by fokenrute
    Hi, In my current project, I have to compare 128bit values (actually md5 hashes) and I thought it would be possible to accelerate the comparison by using SSE instructions. My problem is that I can't manage to find good documentation on SSE instructions; I'm searching for a 128bit integer comparison instruction that let me know if one hash is larger, smaller or equal to another. Does such an instruction exists? PS: The targeted machines are x86_64 servers with SSE2 instructions; I'm also interested in a NEON instruction for the same job.

  • Win32: No Window Appears

    - by SoulBeaver
    I was programming the example code from Frank Luna's book "Introduction to 3D Game Programming with DirectX 10". The code is the first Win32 example in the Appendix A: Windows Programming section. Right now, the program compiles under both VC++ 2008/2010, but no window appears, although the debug session has started and I have to forcefully close it. I have no idea where it is, I'm not using Win32 Console mode, I have closed all other windows and no other IDE or session of VC++ is running. Any idea why this might be happening? PS: I have also checked my Processes. It is indeed running.

  • ASP.NET profile deletion

    - by Ben Aston
    We use the ASP.NET profile subsystem to associate key-value pairs of information with users. I am implementing functionality for the deletion of users. I have been using the ProfileManager.DeleteProfile(string userName) method, but I have noticed that this leaves a row in the aspnet_Users table in the aspnetdb database we use to store the profile information. Clearly, I could manipulate the database directly, but I am reluctant to do so. What is the best way to ensure all information assocaited with a user is deleted from the aspnetdb? PS: there is a tantalising Membership.DeleteUser(string userName, bool deleteEverything) method, but this returns a database connection error. A web.config issue?

  • FreshBooks API Libraries

    - by Hristo
    Hello, I am posting this question as I couldn't find the answer (which is probably very easy, but apparently not for me) anywhere.. I am new to FreshBooks (no only the API) and I want to use it for some automatically generated invoices. I was trying to run some of the source code examples (the PHP and JS libraries in particular): http://developers.freshbooks.com/api/samplecode/ The problem is that I get an error message: "Connection error" Do I need to set up anything else in the example files besides my API and token obtained from the FreshBooks site? P.S.: I am running the examples from a local server but I don't believe that's the problem. Thank you very much in advance!

  • Passing parameters to service by URL - How do I discover the parameter names?

    - by VitalyB
    Hi, I have a report to which I have execute-only access - I don't have the access to the RDL file. This report exposes several parameters which I would like to set from URL. I've successfully changed some parameters using the standard param=data form (as explained here: http://msdn.microsoft.com/en-us/library/ms153586.aspx). However, some parameters don't have the same parameter-prompt and parameter-name. Unfortunately, to pass parameter values by URL I must know the name of the parameter and I don't see how I can deduct from the report and its parameters prompt text. I've tried to inspect the source and post-data but to no avail. Anyone has an idea? Thanks P.S I also stumbled on this: http://odetocode.com/Articles/123.aspx. However, I wasn't able to connect to the web-services of my report server.

  • Care to be taken when serving static content (JS, CSS, Media) from different domain?

    - by Aahan Krish
    Let me try to explain by example. Say website is hosted at example.com (NOT www.example.com). In order to serve static content cookie-free, I've chosen to use a different domain example-static.com. Now, lets consider that my static content is currently served like this: http://example.com/js/script.js http://example.com/css/style.css http://example.com/media/image.jpg ** Now I create a CNAME record aliasing example-static.com to my main domain i.e. example.com so that the static content is served as such: http://example-static.com/js/script.js http://example-static.com/css/style.css http://example-static.com/media/image.jpg ** Is that all I have to do? Will all browsers execute JavaScript files and load web fonts without any security concerns? OR should I be using some .htaccess rules to modify header information and the like? PS: It would be great if you can provide what rules should be added, if need be.

  • TeamCity's build agent unable to find PowerShell

    - by cincura.net
    I have TC's build agent installed on Windows 2008 R2 SP1 Core. The server has PowerShell 2.0 installed (double checked, and actually from PS downloaded the TC installation). Looking at some build configuration I see these being incompatible with this agent, because powershell_x86/powershell_x64 is required. I tried deleting build agents dirs to force upgrade, but no luck. Interestingly if I provide powershell_x86, powershell_x86_Path (and for 64bit) variables into config file manually, everything runs fine. Is there anything I can do to have the build agent find PowerShell automatically? What/where is it looking for it? Maybe the 'Core' is problem.

  • How can I modify an Android bitmap in C++ (JNI/NDK) so that I can use on the Java side?

    - by HardCoder
    I call a C++ function over JNI and pass a RGBA_8888 bitmap, lock it, change the values, unlock it, return and then display it in Java with this C++ code: AndroidBitmap_getInfo(env, map, &info) < 0); AndroidBitmap_lockPixels(env, map, (void**)&pixel); for(i=info.width*info.height-1;i>=0;i--) { pixel[i] = 0xf1f1f1f1; } AndroidBitmap_unlockPixels(env, map); The problem I have is that the bitmaps looks not as I expect it and the pixel values (verified with getPixel) are not the same when I check them in Java from what I set them in C++. When I set the bitmap values to 0xffffffff I get the correct value in Java, but for many others I don't. 0xf1f1f1f1 for example turns into 0xF1FFFFFF. What do I have to do to make it work ? PS: I am using Android 2.3.4

  • Passing extended parameter into Sql 2008 connection string

    - by Pita.O
    Hi, I have a need to support extensive auditing capabilities for a system backing into Sql Server 2008. Since I plan to use LINQ (with no Stored Procs), the database would be a clean, zero contact data repository. However, I need to pratically record a snapshot of every change that happens in the db. So, I thought I should use triggers. But then, I need a user id for the particular user (not the connection string user id) to flow through into the database. In oracle, I should have been able to set up a PROXY USER and the trigger would be able to pick that up. Last I checked, there was no proxy user concept in Sql Server. Does anyone know if there's any extender property I can use to flow through my authenticated user name? ps: I don't mind the impact on connection pooling (if any). Thanks. P

  • Twitter Search API Question

    - by supermogx
    I'm using the twitter search API to get twitter posts based on some keywords, using AND and OR keyword. It works OK, but I seem to get problems using hashtags... For example : Not returning any results : http://search.twitter.com/search.json?q="%23ipad+AND+%23ipod"+OR+"%23joke+AND+%23funny"&rpp=100&callback=? Returning results : http://search.twitter.com/search.json?q="ipad+AND+ipod"+OR+"joke+AND+funny"&rpp=100&callback=? But there's results with #ipod AND #ipad because when I search only for #ipod, I can see a lot of posts with both hashtags. Example : http://search.twitter.com/search.json?q=%23ipad&rpp=100&callback=? P.S. %23 = # Any idea?

  • Whats the most common waste of computing power in javascipt

    - by qwertymk
    We've all seen people who do this jQuery('a').each(function(){ jQuery(this)[0].innerHTML += ' proccessed'; }); function letsPoluteNS() { polute = ''; for (morePolution = 0; morePolution < arguments.length; morePolution++) polute.join(arguments[morePolution]); return polute; } and so on. I was wondering what people have seen the most common javascript/jQuery technique that is slowing down the page and/or wasting time for the javascript engine. PS I know that this question may not seem to fit into whats an accepted question, yet I'm asking for what the most common accepted waste is

  • Just an experiment changing the application data path

    - by Arthur
    When I change the Appication Data path in windows xp registry to a network folder I get this error message on the next system startup: "windows cannot load the user's profile but has logged you with the default profile system" The registry keys are: "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders]" "[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders]" under the names "AppData" and "Local AppData" I dont care if "Windows logins you with the default profile system" but is there a way to disable that message, or change the message timeout form 30 seconds to 0?,or maybe create an script that changes the Application Data path every system startup? P.S. The computer with the shared folder is always on.

  • How to get the list of files in a directory in a shell script?

    - by jrharshath
    Hi, I'm trying to get the contents of a directory using shell script. My script is: for entry in `ls $search_dir`; do echo $entry done where $search_dir is a relative path. However, $search_dir contains many files with whitespaces in their names. In that case, this script does not run as expected. I know I could use for entry in *, but that would only work for my current directory. I know I can change to that directory, use for entry in * then change back, but my particular situation prevents me from doing that. I have two relative paths $search_dir and $work_dir, and I have to work on both simultaneously, reading them creating/deleting files in them etc. So what do I do now? PS: I use bash.

  • sqlite3 date operations when joining two tables in a view?

    - by duncan
    In short, how to add minutes to a datetime from an integer located in another table, in one select statement, by joining them? I have a table P(int id, ..., int minutes) and a table S(int id, int p_id, datetime start) I want to generate a view that gives me PS(S.id, P.id, S.start + P.minutes) by joining S.p_id=P.id The problem is, if I was generating the query from the application, I can do stuff like: select datetime('2010-04-21 14:00', '+20 minutes'); 2010-04-21 14:20:00 By creating the string '+20 minutes' in the application and then passing it to sqlite. However I can't find a way to create this string in the select itself: select p.*,datetime(s.start_at, formatstring('+%s minutes', p.minutes)) from p,s where s.p_id=p.id; Because sqlite as far the documentation tells, does not provide any string format function, nor can I see any alternative way of expressing the date modifiers.

  • jQuery code to track clicks on outgoing links (google analystics)

    - by Tristan
    Hello, I found this on the web: $('a[href^=http]:not("[href*=://' + document.domain + ']")').click(function() { pageTracker._trackPageview('/outgoing/' + $(this).attr('href')); }); But it's not working. In my Google Analytics account there are no /outgoing/ links showing (it's been 24+ hours since I implemented it). What's wrong with this code? I'm using jQuery of course ;) (PS : i already have : <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E")); </script> <script type="text/javascript"> try { var pageTracker = _gat._getTracker("UA MY CODE"); pageTracker._trackPageview(); } catch(err) {}</script>)

  • Have you ever derived a programming solution from nature?

    - by Ryu
    When you step back and look at ... the nature of animals, insects, plants and the problems they have organically solved perhaps even the nature and balance of the universe Have you ever been able to solve a problem by deriving an approach from nature? I've heard of Ant Colony Algorithms being able to optimize supply chain amongst other things. Also Fractal's being the "geometry of nature" have been applied to a wide range of problems. Now that spring is here again and the world is coming back to life I'm wondering if anybody has some experiences they can share. Thanks PS I would recommend watching the "Hunting the Hidden Dimension" Nova episode on fractals.

  • The best way to ensure only 1 copy of bash script is running?

    - by depesz
    What is the simplest/best way to ensure only 1 copy of given script is running - assuming it's bash on linux? At the moment I'm doing: ps -C script.name.sh > /dev/null 2>&1 || ./script.name.sh but it has several issues: it puts the check outside of script it doesn't let me run the same script from separate accounts - which I would like sometimes. -C checks only first 14 characters of process name Of course I can write my own pidfile handling, but I sense that there should be some simple way to do it.

  • Visual Studio 2008 Navigate Forewards/Backwards Buttons Don't Work As Expected

    - by TheCloudlessSky
    I just installed VS2008 on my new Win7 box. I have Navigate Backwards and Navigate Forwards buttons on my tool bar. When I change between documents, I do NOT see a list drop down for each of the buttons like should be seen here after opening multiple documents and switching between their methods: How it should work. Instead, I just see the buttons without drop downs. I find that navigating forwards and backwards doesn't work as it should. I should be able to click in different lines of the code and press the nav back/forwards buttons to jump between lines. This is not the case. Any suggestions? Thanks in advanced. PS - I installed SP1 just to see and nothing changed.
