  • Calling Class from another File ASP.NET VB.NET

    - by davemackey
    Lets say I have a class like this in class1.vb: Public Class my_class Public Sub my_sub() Dim myvar as String myvar = 10 Session("myvar") = myvar End Sub End Class Then I have a ASP.NET page with a code-behind file, default.aspx and default.aspx.vb and I want to call my_class. I'm doing the following, but it doesn't work: Imports my_app.my_class Partial Public Class _default Inherits System.Web.UI.Page Protected Sub Page_Load(ByVal sender as Object, ByVal e as System.EventArgs) Handles Me.Load my_class() End Sub End Class I get a "Reference to a non-shared member requires an object reference"

  • Java RegExp ViewState

    - by CDSO1
    I am porting some functionality from a C++ application to java. This involves reading non-modifiable data files that contain regular expressions. A lot of the data files contain regular expressions that look similar to the following: (?<=id="VIEWSTATE".*?value=").*?(?=") These regular expressions produce the following error: "Look-behind group does not have an obvious maximum length near index XX" In C++ the engine being used supported these expressions. Is there another form of regexp that can produce the same result that can be generated using expressions like my example as input?

  • How to create a column that can never be updated?

    - by Randy Minder
    In SQL Server 2008, is it possible to create a column that can have a value inserted into it, but can never be updated? In other words, the column can have an initial value inserted into it, but once it contains a non-null value, it can never be changed. If possible, I would prefer to do it without using a trigger. Thanks - Randy

  • Containers of reference_wrappers (comparison operators required?)

    - by kloffy
    If you use stl containers together with reference_wrappers of POD types, the following code works just fine: int i = 3; std::vector< boost::reference_wrapper<int> > is; is.push_back(boost::ref(i)); std::cout << (std::find(is.begin(),is.end(),i)!=is.end()) << std::endl; However, if you use non-POD types such as (contrived example): struct Integer { int value; bool operator==(const Integer& rhs) const { return value==rhs.value; } bool operator!=(const Integer& rhs) const { return !(*this == rhs); } }; It doesn't suffice to declare those comparison operators, instead you have to declare: bool operator==(const boost::reference_wrapper<Integer>& lhs, const Integer& rhs) { return boost::unwrap_ref(lhs)==rhs; } And possibly also: bool operator==(const Integer& lhs, const boost::reference_wrapper<Integer>& rhs) { return lhs==boost::unwrap_ref(rhs); } In order to get the equivalent code to work: Integer j = { 0 }; std::vector< boost::reference_wrapper<Integer> > js; js.push_back(boost::ref(j)); std::cout << (std::find(js.begin(),js.end(),j)!=js.end()) << std::endl; Now, I'm wondering if this is really the way it's meant to be done, since it seems impractical. It just seems there should be a simpler solution, e.g. templates: template<class T> bool operator==(const boost::reference_wrapper<T>& lhs, const T& rhs) { return boost::unwrap_ref(lhs)==rhs; } template<class T> bool operator==(const T& lhs, const boost::reference_wrapper<T>& rhs) { return lhs==boost::unwrap_ref(rhs); } There's probably a good reason why reference_wrapper behaves the way it does (possibly to accomodate non-POD types without comparison operators?). Maybe there already is an elegant solution and I just haven't found it.

  • DateTime.Now question

    - by Tony
    Hello, I am using a couple varaibles that have value of DateTime.now for both database and web services purpose. Now, if someone asks you that how I am handling non-machine timezone, is that question refering that how the code will handle in case if the application gets deployed to machines in different time zones? To give more information, the application will manipulate data from different time zones. Thank you.

  • Why is FLT_MIN equal to zero on OS X?

    - by Nick Forge
    limits.h specifies limits for non-floating point math types, e.g. INT_MIN and INT_MAX. These values are the most negative and most positive values that you can represent using an int. In float.h, there are definitions for FLT_MIN and FLT_MAX. If you do the following: NSLog(@"%f %f", FLT_MIN, FLT_MAX); You get the following output: FLT_MIN = 0.000000, FLT_MAX = 340282346638528859811704183484516925440.000000 FLT_MAX is equal to a really large number, as you would expect, but why does FLT_MIN equal zero?

  • Ruby off the rails

    - by JesperE
    Sometimes it feels that my company is the only company in the world using Ruby but not Ruby on Rails, to the point that Rails has almost become synonymous with Ruby. I'm sure this isn't really true, but it'd be fun to hear some stories about non-Rails Ruby usage out there.

  • Easy to use web-based reporting tool

    - by SuperFurryToad
    I'm looking for recommendations for an easy to use reporting/business intelligence tool that can interface with an sql server or access database. It can be web-based or a desktop tool. Ideally it would be freeware or low cost, and easy to use for users who are not that technically savvy (below the level of someone who can generate reports and complicated queries in Access). Any tools I've seen so far (such as Crystal Reports) are either too expensive or too complicated to use for non-power users.

  • Change Variable back to original value after Regex matching.

    - by Brad Johansen
    I just "finished" expanding my Palindrome Tester, made in C#. To allow for phrases I added a simple regex match for all non-alphanumeric characters. At the end of the program it states " is(n't) a palindrome." But now with the regex it prints the no spaces/punctuation version of it. I would like to be able to print the original user input. How do I do that? Here is my program: http://gist.github.com/384565

  • Zend_Search_Lucene and range search

    - by ranza
    I have a bunch of int key fields in my index and trying to do a simple range search like this: `gender:1 AND height:[120 TO 180]` This should give me male in the height range 120 to 180. But for some reason i get this exception: `At least one range query boundary term must be non-empty term` How would i debug this? Is it just Zend_Search_Lucene being buggy?

    Hello Sun's virtualbox windows binaries are under 'non-commercial' license so can't be used in any company. But source code is GPL. Is it any resource on the network that has a virtualbox compiled binaries for windows? Added a bounty to see if I can get a little more feedback.

  • SharePoint Licensing

    - by Adam
    Hi - we are thinking of using SharePoint to host a web app for which we will allow internal staff and licensed external customers to access a website built on SharePoint. I am thinking that for each authenticated user (logged in) we would need an OS CAL & a SharePoint CAL & we would need a processor license for SQL Server - Is this correct & what about non-authemticatedc website "browsers"? Any advice much appreciated.

  • Allow incoming connections on Windows Server 2008 R2

    - by Richard-MX
    Good day people. First, im new to Windows Server. I've always used Linux/Apache combo, but, my client has and AWS EC2 Windows Server 2008 R2 instance and he wants everything in there. Im working with IIS and PHP enabled as Fast-CGI and everything is working, but, i cant see the websites stored in it from internet. The public DNS that AWS gave us for that instance is: http://ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com/ But, if i copy paste that address, i get nothing, no IIS logo or something like that. My common sense tells me that maybe the firewall could be blocking the access. Can anyone help me and tell where to enable some rules to get this thing working? I don't wanna start enabling rules at random and make the system insecure. If you need any additional info, you can ask me and i will provide it. Thanks in advance. UPDATE: Amazon EC2 display this: Public DNS: ec2-XX-XXX-XXX-121.us-west-2.compute.amazonaws.com Private DNS: ip-XX-XXX-XX-252.us-west-2.compute.internal Private IPs: XX.XXX.XX.25 In my test microinstance, i just to use the Public DNS address (the one that starts with "ec2") and it works like a charm (of course, the micro instance have its own Public DNS im not assuming same address for both instances...) However, for the large instance, i tried to do the same. Set up everything as in the micro instance but if i use the Public DNS, it doesnt load anything. Im suspicious about the Windows Firewall, but, the HTTP related stuff is enabled. What should i do to get access to the large instance? I don't want to set up the domain yet, i want access from an amazon url. 2ND EDIT: all fixed. Charles pointed that maybe Security Groups was not properly set up for the instance. He was right. Just added HTTP service to the rules and all works good.

  • How to block/avoid a particular IP when connecting to websites?

    - by Mark
    I'm having trouble connecting to a particular website. I can view it through a proxy, but not from home. So I ran a traceroute: Tracing route to fvringette.com [76.74.225.90] over a maximum of 30 hops: 1 <1 ms <1 ms <1 ms <snip> 2 * * * Request timed out. 3 9 ms 7 ms 27 ms rd2bb-ge2-0-0-22.vc.shawcable.net [64.59.146.226] 4 8 ms 7 ms 7 ms rc2bb-tge0-9-2-0.vc.shawcable.net [66.163.69.41] 5 10 ms 9 ms 9 ms rc2wh-tge0-0-1-0.vc.shawcable.net [66.163.69.65] 6 27 ms 23 ms 22 ms ge-gi0-2.pix.van.peer1.net [206.223.127.1] 7 18 ms 18 ms 20 ms 10ge.xe-0-2-0.van-spenc-dis-1.peer1.net [216.187.89.206] 8 9 ms 11 ms 10 ms 64.69.91.245 9 * * * Request timed out. 10 * * * Request timed out. ... Looks like this "64.69.91.245" is somehow blocking me. Can I tell my computer to avoid/bypass that IP when trying to connect?

  • overloading friend operator<< for template class

    - by starcorn
    Hello, I have read couple of the question regarding my problem on stackoverflow now, and none of it seems to solve my problem. Or I maybe have done it wrong... The overloaded << if I make it into an inline function. But how do I make it work in my case? warning: friend declaration std::ostream& operator<<(std::ostream&, const D<classT>&)' declares a non-template function warning: (if this is not what you intended, make sure the function template has already been declared and add <> after the function name here) -Wno-non-template-friend disables this warning /tmp/cc6VTWdv.o:uppgift4.cc:(.text+0x180): undefined reference to operator<<(std::basic_ostream<char, std::char_traits<char> >&, D<int> const&)' collect2: ld returned 1 exit status template <class T> T my_max(T a, T b) { if(a > b) return a; else return b; } template <class classT> class D { public: D(classT in) : d(in) {}; bool operator>(const D& rhs) const; classT operator=(const D<classT>& rhs); friend ostream& operator<< (ostream & os, const D<classT>& rhs); private: classT d; }; int main() { int i1 = 1; int i2 = 2; D<int> d1(i1); D<int> d2(i2); cout << my_max(d1,d2) << endl; return 0; } template <class classT> ostream& operator<<(ostream &os, const D<classT>& rhs) { os << rhs.d; return os; }

  • How can I model the data in a multi-language data editor in WPF with MVVM?

    - by Patrick Szalapski
    Are there any good practices to follow when designing a model/ViewModel to represent data in an app that will view/edit that data in multiple languages? Our top-level class--let's call it Course--contains several collection properties, say Books and TopicsCovered, which each might have a collection property among its data. For example, the data needs to represent course1.Books.First().Title in different languages, and course1.TopicsCovered.First().Name in different languages. We want a app that can edit any of the data for one given course in any of the available languages--as well as edit non-language-specific data, perhaps the Author of a Book (i.e. course1.Books.First().Author). We are having trouble figuring out how best to set up the model to enable binding in the XAML view. For example, do we replace (in the single-language model) each String with a collection of LanguageSpecificString instances? So to get the author in the current language: course1.Books.First().Author.Where(Function(a) a.Language = CurrentLanguage).SingleOrDefault If we do that, we cannot easily bind to any value in one given language, only to the collection of language values such as in an ItemsControl. <TextBox Text={Binding Author.???} /> <!-- no way to bind to the current language author --> Do we replace the top-level Course class with a collection of language-specific Courses? So to get the author in the current language: course1.GetLanguage(CurrentLanguage).Books.First.Author If we do that, we can only easily work with one language at a time; we might want a view to show one language and let the user edit the other. <TextBox Text={Binding Author} /> <!-- good --> <TextBlock Text={Binding ??? } /> <!-- no way to bind to the other language author --> Also, that has the disadvantage of not representing language-neutral data as such; every property (such as Author) would seem to be in multiple languages. Even non-string properties would be in multiple languages. Is there an option in between those two? Is there another way that we aren't thinking of? I realize this is somewhat vague, but it would seem to be a somewhat common problem to design for. Note: This is not a question about providing a multilingual UI, but rather about actually editing multi-language data in a flexible way.

  • Xorg input devices fail without udev

    - by Sampo
    What I am trying to do: Launch Xorg server without udev device manager. What I have tried to do: Make sure that /dev/ has all required nodes, such as /dev/input/*. Make sure that all required kernel modules are loaded. Launch Xorg. What happens: Xorg starts up as excepted. Xorg loads correct GPU driver and sets right screen resolution. Xorg blocks all input devices (keyboard, mouse), Alt+F[1-12] does not work (can't go back to tty1). Unraw'ing keyboard to take its control from X removes blocking and after unraw I can Alt+F1 back to tty1. Xorg still does not handle any input. Why I think that it should work: Same configuration works well if udev is loaded. Loading udev does not add or modify /dev/ contents, all nodes stays same. My main question is: How to make Xorg input devices work without udev? Any additional information about how Xorg really uses/detects/grabs keyboard would be helpful. And any additional information about what udev really does (other than populating /dev/) would also be helpful.
