  • Using a dropdown on a static webpage as a DataSource in C#.net

    - by Matt
    I know this is a terrible way of doing things, but it's for an internal app where security is no issue. Basically, an old group created a php page with a drop down and this drop down is populated with entries from a DB. The DB owner is currently absent and for the sake of time, I would just need something that turns the entries in that drop down, always at the same url with the same ID every load into a List. Is there a quick, painless way to do this in .NET?

  • when to make a method static

    - by Don
    Hi, I'd like to know how people decide whether to define a method as static. I'm aware that a method can only be defined as static if it doesn't require access to instance fields. So lets say we have a method that does not access instance fields, do you always define such a method as static, or only if you need to call it statically (without a reference to an instance). Perhaps another way of asking the same question, is whether you use static or non-static as the default? Thanks, Don

  • Eclipselink and update trigger on multiple access to the database

    - by Raven
    Hi, in my project I have a database which many clients connect to. Concurrent access and writing works well. The problem now is not to reload the data every second from the database to always have the current status of the data. Does Eclipselink provide a trigger mechanism on (automatically?) reload the data if the database is changed? How would one use this trigger? Thanks!

  • Multiple returns: Which one sets the final return value?

    - by DR
    Given this code: String test() { try { return "1"; } finally { return "2"; } } Do the language specifications define the return value of a call to test()? In other words: Is it always the same in every JVM? In the Sun JVM the return value is 2, but I want to be sure, that this is not VM-dependant.

  • How to count how many items for distinct items in mysql?

    - by Vincent Duprez
    Imagine a have a table with a column named status: status ------ A A A B C C D D D How can I count how many rows have A, how many rows have B etc? this kind of output: A |B |C |D |E ------------------ 3 |1 |2 |3 |0 As for E = O , this will always be A,B,C,D and E Output should be one row (thus 1 query). When doing a distinct count (most returning answer on my searches, it does return how many different elements there are, 4 in this case...)

  • QueryString problem in .aspx - prints out nothing

    - by user321256
    I need to print out the querystring value "?type=xxx" inside my .aspx-page, why doesn't this work: <%= Request.QueryString("type") %> While this does: <%= Request.QueryString(0) %> The first prints out nothing, the second one prints out the value as expected, but it isn't always the first value I want... Any ideas?

  • Errors in c++ faq lite?

    - by Gianluca
    Hello, I'm reading questions and answers around here for a few days. I have seen the c++ faq lite at Parashift has been mentioned many times. Personally I have always considered it to be a good reference, not my favourite one but certainly useful. Here I have seen somebody advising it, but many others commenting against it instead. Somebody mentioned it's full of mistakes. Could you please point out which are the major errors in there, if any?

  • Effect of suffixes in memory to cache operations

    - by tur1ng
    In x86 GNU Assembler there are different suffixes for memory related operations. E.g.: movb, movs, movw, movl, movq, movt(?) Now my question is the following: Does the suffix has ANY effect on how the processor is getting the data out of main memory or will always be one or more 32-bit (x86) chunks loaded into the cache ? What are the effects beside the memory access?

  • iPhone Safari Web Application not using cache at all?

    - by Liuyi Sun
    Hi, guys, I've been developing an iphone web application for a while, and encountered a weird problem: when open the web app in safari(with safari chrome, not starting it from home screen), safari can generate proper "If-Not-Modified-Since" and "If-None-Matches", so the server simply gives 304 Not Modified to speed up the process. however, when starting the app from home screen, safari seems to forget these two headers, and server always replies with 200 OK... any ideas for this?

  • My login controller doesn't work. Problem with fetching username.

    - by misterwebz
    Currently my login controller doesn't work because i can't seem to fetch the username and password. I'm currently using something like this: form_username = str(request.params.get('username')) db_user = meta.Session.query(User).filter_by(username=form_username) if db_user is None: return redirect('auth/error') No matter which username is use, db_user always returns True and thus never goes to auth/error. I used the shell to play with this and i was able establish a connection with the database, so i'm not sure what i'm doing wrong here.

  • How does msbuild decide whether it needs to rebuild a C# library or not?

    - by Peter Mounce
    Per subject, how does msbuild decide whether it needs to rebuild a library (ie, invoke csc), or not, when it is run against a C# project file? I imagine (but want to confirm): If there's no output directory, rebuild (duh :) ) If a C# file has changed, rebuild If an included file marked copy-always has changed, rebuild or is it smart enough to not rebuild, but just copy the file to the existing output? If an included file marked copy-if-newer has changed, rebuild same question as above

  • Implementation of java.lang.Random in PHP and C

    - by justinhj
    I'm looking for a random number generator that I can run in PHP, C and Java that will always return the same sequence of numbers for a given seed. Here's the Java implementation I would use: java.util.random source Whilst this would be fairly straightforward to port to C and PHP, there is potentially a lot of work to get all the edge cases correct and handle differences in number representation. I'd be extremely happy to just copy and paste a fully tested version should it exist.

  • How to know if your Unit Test is "right-sized"?

    - by leeand00
    One thing that I've always noticed with my unit tests is that they get to be kind of verbose; seeing as they could also be not verbose enough, how do you get a sense of when your unit tests are the right size? I know of a good quote for this and it's: "Perfection is achieved, not when there is nothing left to add, but when there is nothing left to remove." - Antoine de Saint-Exupery.

  • How to obtain the correct physical size of the monitor?

    - by KindDragon
    How can I get the size of the display in centimeters or inches? This code does not always works correctly: HDC hdc = CreateDC(_T("DISPLAY"),dd.DeviceName,NULL,NULL); int width = GetDeviceCaps(hdc, HORZSIZE); int height = GetDeviceCaps(hdc, VERTSIZE); ReleaseDC(0, hdc) Especially for multi-monitor configuration. Update: I need to get the size just for ordinary monitors, which have a constant physical size.
