• Server.Transfer - What could be the issue here?

  - by Younes

  We have implemented a website with the ability for the user to post his actioncode. This then will be checked by the code and when the user has a price the website will Server.Transfer him to another page. The strange thing here is that the user information will be submitted to the database and the actioncode can't be used again. Here we go... I have one user in this database that is inserted twice very fast after the first time he was added. This are the timestamps: 2010-04-23 07:54:41.133 2010-04-23 07:54:41.417 The insert statement is only called once from the code and the user gets Server.Transfered to the Price.aspx page where he sees what price he won. How can it be that this happened? I'm guessing the user hitted F5 but then he had to be very very fast... Thx!

• Why does the CPU window always appear when trying to debug my project after a rebuild in Delphi 2010

  - by James

  Hi, Whenever I rebuild my application and try to step into a break-point the CPU window always appears. From what I understand the CPU window appears when DCU does not match up with the source file, however, in my case the DCU's are defintely being re-compiled and there are no old ones lying around or anything like that. The strange thing here is if I close down the application and re-open the project, place the breakpoint and run it works fine. I can even modify files and just press F9 to run the project and it works fine....it only seems to be when I rebuild the project (via IDE Project menu or the project context menu) that this CPU window never breaks into the source (even though it can find it!). I also noticed in the callstack a unit called Generics is always the top of the stack, never the unit my break point is in, this is no way related to where my break point is. Any ideas?

• Interacts with dialog/whiptail on early boot rcX.d stage?

  - by nm

  Hi buddies, I'm developing on Ubuntu based, actually I got one script in-charged on GUI(console) setup. It runs before another scripts (rcX.d) start. Currently, I installed this script on rc2.d and start earlier than other ones. But when run on real machine, I can't input any keystroke on "dialog --inputbox" or whiptail through shell script. Additionally, It runs well on my Virtual Machine (Virtual Box and Vmware), that's so strange! So, does anybody give some help or point me any clues for overcome this ? Thanks

• High CPU - What to do.

  - by Udi Kantzuker

  I have a high CPU problem with MYSQL using "top" ( linux ) shows cpu peaks of 90%. I was trying to find the source of the problem, turned on general log and slow query log, The slow query log did not find anything. The Db contains a few small tables and one large table that contains almost 100k rows, Database Engine is MyIsam. strange thing i have noticed that on the large table, select, insert are very fast but update takes 0.2 - 0.5 secs. already used optimize and repair and no improvement. the table is being updated frequently, could this be the source of the high CPU% ? What can i do to improve this?

• [Java6] Same source code, Eclipse build success but Maven (javac) fails

  - by EnToutCas

  Keep getting this error when compiling using Maven: type parameters of <X>X cannot be determined; no unique maximal instance exists for type variable X with upper bounds int,java.lang.Object Generics type interference cannot be applied to primitive types. But I thought since Java5, boxing/unboxing mechanism works seamlessly between primitive types and wrapper classes. In any case, the strange thing is Eclipse doesn't report any errors and happily compiles. I'm using JDK1.6.0_12. What could possibly be the problem here?

• RSpec: in-depth differences between before(:all) and before(:each)

  - by gmile

  Ok, so I've ran into a very strange issue, directly connected with before blocks. I'm doing a integration testing via Watir and RSpec. For a simple test to check if user can perform a login I'm creating a 'user' record in the db by means of factory_girl. So I put the following code: before(:each) do @user = Factory(:user) end if "should perform a login" do # do stuff end In do stuff I call a browser and see how the user tries to login. Unfortunately, somehow he cannot do that — "Username isn't valid". After some investigation I discovered that if I put the code for creating user in before(:all) block, everything magically works. How's that? What's the difference between :all and :each in this context? Also, If I put the code for creating user actually in the test body, it still doesn't work (i.e. user somehow isn't added to the DB or something).

• ondevicemotion in Chrome desktop returns true

  - by Martin Klasson

  I am using a "shake" function from github - and it has a detection that is browser-based javascript. //feature detect this.hasDeviceMotion = 'ondevicemotion' in window; This though yields true even on Chrome on OS X. It feels strange, since I am not willing to shake my monitor on my desktop. Safari on OS X gives me "false" in return when testing. I have searched but not been able to find out why Chrome decided to take this path. It bugs me. Is there a better way to make this detection? Not all "mobile devices" has shake as well.. or does not let the browser have that capability, as it does not seem to work in windows phones.

• JUnit unable to find tests in Eclipse

  - by mikera

  I have a strange issue with JUnit 4 tests in Eclipse 3.5 that I couldn't solve - any hints gratefully received! Initially: I had a test suite working properly, with 100+ tests all configured with JUnit 4 annotations. I'd run these typically by right clicking on my source folder and selecting "Run as JUnit test". All worked perfectly. Now: When I try to run the test messages all I get is an error "No tests found with test runner 'JUnit 4'". Any idea what is happening? I simply can't work out what could have changed to make this fail. My guess is that it is some configuration issue based on the build path or class path?

• Why use of session name and session id in the get variables does not work?

  - by Roman

  I have the following code: $location .= 'red=no&'.session_name() . "=". session_id(); $content = file_get_contents($location); echo $content; If I run it, noting is displayed in my browser. However, if I modify it in the following way: $location .= 'red=no'; $content = file_get_contents($location); echo $content; everything works fine (I see the content in my browser). What is also strange, if I display the value of the $location variable from the first example (url) and manually paste it in the address line of my browser, I do see the content. So, my browser is able to use this URL and file_get_contents not. Does anybody know how it can be explained?

• Unresolved External Symbol

  - by TomO

  I am working on wrapping a large number of .h and .lib files from native C++ to Managed C++ for eventual use as a referenced .dll in C#. I have the .lib files linked in and everything has been going smoothly so far. Upon wrapping the latest .h file, I hit a snag when 2 functions came back with the link error: error LNK2019: unresolved external symbol __imp__htonl@4 referenced in function "public: void __thiscall Field::setCharacter(unsigned char,int)" (?setCharacter@Field@@QAEXEH@Z) myutils.lib I have referenced "myutils.lib" in the linker options, so that shouldn't be the issue. What's strange is that I have about 20 functions in this particular .h file and all of the rest are linking just fine except for 3 functions. Any ideas?

• SQL Server Operating System

  - by NDeveloper

  Hi, I found an interesting article about Platform layer for SQL Server. It talks about SQLOS. As I understand it is an abstraction layer between the hardware and SQL Server. So does it mean that we can have SQL Server installed without installing windows? It sounds very strange to me... Please tell me where it is possible to find more info on this. And also whoever have used SQLOS and for what reason? What are the main advantages from developers view?

• Extract domain from url (including the hard ones)

  - by karl

  I'm trying to write (or just find an existing) PHP method that can take a link and extract the url. The trick is, it needs to hold under the weight of strange looking domains like: www.champa.kku.ac.th Looking at this one myself with human eyes, I still guessed it incorrectly: thought the domain would be kku.ac.th but that gives a dns error when visiting. So anyone knows of a good way to reliably extract the domain from url: http://site.com/hello.php http://site.com.uk/hello.php http://subdomain.site.com/hello.php http://subdomain.site.com.uk/hello.php http://www.champa.kku.ac.th/hello.php // and even the one I couldn't tell

• Is there a pre-made Continuous Integration solution for .NET applications?

  - by Brett Rigby

  From my perspective, we're constructing our own 'flavour' of NAnt/Ivy/CruiseControl.Net in-house and can't help but get the feeling that other dev shops are doing exactly the same work, but then everybody is finding out the same problems and pitfalls with it. I'm not complaining about NAnt, Ivy or CruiseControl at all, as they've been brilliant in helping our team of developers become more sure of the quality of their code, but it just seems strange that these tools are very popular, yet we're all re-inventing the CI-wheel. Is there a pre-made solution for building .Net applications, using the tools mentioned above?

• getResourceAsStream() is always returning null

  - by Andreas Grech

  I have the following structure in a Java Web Application: TheProject -- [Web Pages] -- -- [WEB-INF] -- -- -- abc.txt -- -- index.jsp -- [Source Packages] -- -- [wservices] -- -- -- WS.java In WS.java, I am using the following code in a Web Method: InputStream fstream = this.getClass().getResourceAsStream("abc.txt"); But it is always returning a null. I need to read from that file, and I read that if you put the files in WEB-INF, you can access them with getResourceAsStream, yet the method is always returning a null. Any ideas of what I may be doing wrong? Btw, the strange thing is that this was working, but after I performed a Clean and Build on the Project, it suddenly stopped working :/

• linq .net with dynamically generated controls

  - by Stuart

  This is a very strange problem and i really dont have a clue whats causing it. What is supposed to happen is that a call to the BLL then DAL returns some data via a linq SPROC call. The retunred IMultipleResults object is processed and all results stored in a hashtable. The hashtable is stored in session and then the UI layer uses these results to dynamically generate some gridviews. Easy you would think. But if i run the code i dont get any gridviews. If i take out the call to the BLL and DAL the gridviews appear but with nothing in them? Why is it the page renders correctly when i take out the call to get the data? Thanks.

• Glib::ustring and Japanese characters

  - by user294787

  Glib::ustring is supposed to work well with UTF8 but I have a problem when working with Japanese strings. If you compare those two strings, "???" and "???", using == operator or compare method, it will answer that those two strings are equals. I don't understand why. How Glib::ustring works ? The only way I found to get false to the comparison is to compare strings of different sizes. For example "?????" and "????". Very strange...

• XNA Multi-Thread Jitters

  - by Ice Phoenix

  Hi guys, brand new question. Just implemented multi-threading into my XNA game as it was unable to keep up with using 1 processor. MT is all implemented fine and everything, however the player seems to jitter all over the spot every now and then. I originally thought it was a loss of data between the update and render, but even when i did the player update in the render it did the same thing. It's not a memory/processor issue as i'm no where near maxing out my RAM or processors. It's strange aswell because none of the other entities in the game seem to have any of these issues. Any ideas at all??

• jQuery click event behaves differently with live function in Firefox

  - by fjsj

  Using the event click with live function leads to strange behavior when using Firefox*. With live in Firefox, click is triggered when right-clicking also! The same does not happen in Internet Explorer 7 neither in Google Chrome. Example: Without live, go to demo and try right clicking the paragraphs. A dialog menu should appear. With live, go to demo and try right clicking "Click me!". Now both dialog menu and "Another paragraph" appear. *tested with firefox 3.5.3

• What did they program this toy with?

  - by Trix

  A rather strange question: I'm often asking myself with what programming languages things were created. I recently found this toy mini computer I played with when I was 13 or so at home. (Note: It is not one of those toy "notebooks", it's really small and came as an extra with a magazine) "Features": Hadware: LCD with a small field of pixels where the games were going on, besides that some stats such as score, highscore etc. Sounds and horrible music when started A really small "keyboard" with a wire Software: At least 14 or so games, from Snake over Tetris and Breakdown to some abomination of a car racing game A calculator Game selecting menu An alarm clock Inside there is a really small circuit board, I don't want to open the thing up now, though. Can you imagine if the games and "Operating System" of this thing where actually programmed using a language? If yes, what language could it be? If not with a programming language, how else was it created?

• visual studio 2008 keyboard gets locked when editing source controlled files

  - by Rama

  Hi, I am facing a strange issue with editing source controlled files (especially aspx files) using visual studio 2008. when I check out and edit the file, I can edit fine for few seconds and after that keyboard gets locked and I can't type anything (it doesn't affect the files not added to source control). as soon it is locked, if I try to type, the focus shifts to solution explorer and other windows and sometimes it freezes and doesn't respond at all. I tried uninstalling and reinstalling visual studio, reinstalling the source control plug-in. none of it worked. not sure if it is my machine or my profile. Please help if you have any clues. I can't see any other solution for this except rebuilding the machine Thanks, Rama

• Trying to send text message using sp_send_dbmail truncates url in body

  - by Dabas

  I'm using send_dbmail to send a text message to customers. This is the following sql: exec msdb.dbo.sp_send_dbmail @recipients='[email protected]', @body='check out this url https://www.someurl.com/directory/blah.aspx', @subject='I am the subject!' The body gets truncated to "check out this url https://www.someurl.com/directory/blah.as" (the "px" is removed from the end of the url). I've ruled out message length as I have tried sending just "www.google.com/test.aspx" and the "px" is removed as well. Another strange thing, when I try forwarding the text message to myself and add the "px" back on myself, it works. It also works if I send a email from outlook with the same body. Any ideas? Thanks.

• Understanding c++ block of code

  - by kotoko

  I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.
