  • Does SQL Server 2005 error message numbers back to the asp.net application?

    - by Duke
    I'd like to get the message number and severity level information from SQL Server upon execution of an erroneous query. For example, when a user attempts to delete a row being referenced by another record, and the cascade relationship is "no action", I'd like the application to be able to check for error message 547 ("The DELETE statement conflicted with the REFERENCE constraint...") and return a user friendly and localized message to the user. When running such a query directly on SQL Server, the following message is printed: Msg 547, Level 16, State 0, Line 1 <Error message...> In an Asp.Net app is this information available in an event handler parameter or elsewhere? Also, I don't suppose anyone knows where I can find a definitive reference of SQL Server message numbers?

  • Prototype and jQuery concatenation failure

    - by Corey Hart
    I found something strange when trying to concatenate prototype and jQuery. It seems as though when concatenated, the $ jquery reference doesn't get overwritten by prototype. I've built two test cases to single this out, and it's failing in Chrome8 and FF 3.6. Test Case 1 - Without Concatenation jQuery and Prototype are loaded separately with different script tags. jQuery is loaded first, Prototype second. Test Case 2 - With Concatenation jQuery and Prototype are concatenated into a single file, and loaded with a single script tag. jQuery is first in the script, and prototype is added second. These should act identically, but the second test is throwing errors because the $ function in prototype doesn't overwrite the $ jquery reference. Did I set these up wrong, or are browsers rendering javascript differently when it's all in the same file?

  • Installing ADT plugin 16.0.1 on Eclipse Indigo- windows

    - by user1136529
    When I try to install the ADT 16.0.1 plugin on Eclipse Indigo java developer edition release 1 or Helios normal edition release 2, I get the following error: Cannot complete the install because one or more required items could not be found. Software currently installed: Shared profile 1.0.0.1316138460759(SharedProfile_epp.package.java 1.0.0.1316138460759) Missing requirement: Shared profile 1.0.0.1316138460759 (SharedProfile_epp.package.java 1.0.0.1316138460759) requires 'org.maven.ide.eclipse [1.0.100.20110804-1717]' but it could not be found I've tried to lookup the package it's refering to on apache, JDK reference and android developer reference but no luck! This's not my first time installing ADT, I already have it installed on Ubuntu and it works. I also had the old release (ADT 15) installed on Eclipse galileo on windows, but I re-installed windows (i'm running windows 7 ultimate by the way) and I can run the old release but it's very good developing with ICS API-s. So, if anyone could help, it would be highly appreciated.

  • What's your favourite programming language, and its killer feature?

    - by eplawless
    Each language I've used has had its pros and cons, but some features have really shone through as being indispensible, shining examples of how to design a programming language to make programmers happy. I use PHP a lot at work, and the one thing I really miss when moving to other languages is PHP's foreach: foreach($items as $item) //iterate through items by value foreach($items as &$item) //iterate through items by reference foreach($items as $i => $item) //by value, with indices foreach($items as $i => &$item) //by reference, with indices In C#, I'm kind of smitten with the built-in multicast delegate system, as well as the way it handles getters and setters. So what's your favourite/favorite language, and what feature makes it awesome?

  • C++ string sort like a human being?

    - by Walter Nissen
    I would like to sort alphanumeric strings the way a human being would sort them. I.e., "A2" comes before "A10", and "a" certainly comes before "Z"! Is there any way to do with without writing a mini-parser? Ideally it would also put "A1B1" before "A1B10". I see the question "Natural (human alpha-numeric) sort in Microsoft SQL 2005" with a possible answer, but it uses various library functions, as does "Sorting Strings for Humans with IComparer". Below is a test case that currently fails: #include <set> #include <iterator> #include <iostream> #include <vector> #include <cassert> template <typename T> struct LexicographicSort { inline bool operator() (const T& lhs, const T& rhs) const{ std::ostringstream s1,s2; s1 << toLower(lhs); s2 << toLower(rhs); bool less = s1.str() < s2.str(); std::cout<<s1.str()<<" "<<s2.str()<<" "<<less<<"\n"; return less; } inline std::string toLower(const std::string& str) const { std::string newString(""); for (std::string::const_iterator charIt = str.begin(); charIt!=str.end();++charIt) { newString.push_back(std::tolower(*charIt)); } return newString; } }; int main(void) { const std::string reference[5] = {"ab","B","c1","c2","c10"}; std::vector<std::string> referenceStrings(&(reference[0]), &(reference[5])); //Insert in reverse order so we know they get sorted std::set<std::string,LexicographicSort<std::string> > strings(referenceStrings.rbegin(), referenceStrings.rend()); std::cout<<"Items:\n"; std::copy(strings.begin(), strings.end(), std::ostream_iterator<std::string>(std::cout, "\n")); std::vector<std::string> sortedStrings(strings.begin(), strings.end()); assert(sortedStrings == referenceStrings); }

  • The pros and cons of use JSON for WCF service

    - by brz dot net
    What are the pros and cons of the following 2 cases: Case I: Traditional way: Add service reference in project. Create object and Get data from service on server side and bind to asp.net grid. Case II: Update Service for JSON behavior. Add service reference in project. Call service from javascript to get data. Bind data to jquery grid. Which one is the best approach and why?(Not developer point of view) If there is another approach which is more optimized, please explain it.

  • Silverlight calling windows workflow foundation as a web service

    - by wissem
    hi, I'm trying to call a windows workflow foundation published as a web service from a Silverlight project. When I call it from a console application it works fine because I can add a web reference then I just make an instance of that webservice then I invoke the method I want. The problem is in the silverlight project cause i can just add a service reference so I find myself working with soap stuff that doesn't work at all, and here is the code: private void btnUpdate_Click(object sender, RoutedEventArgs e) { xxxxxxx.Workflow1_WebServiceSoapClient zer = new xxxxx.Workflow1_WebServiceSoapClient(); zer.demanderSubmitReportCompleted += new EventHandler<xxxxxxxxxxxxxxx.demanderSubmitReportCompletedEventArgs>(service2); zer.demanderSubmitReportAsync("zzz", 20000); } public void service2(object sender, xxxxx.demanderSubmitReportCompletedEventArgs e) { string a = e.Result; } plz help ,thanks

  • Shared static classes between AppDomains in loaded library code

    - by Christian Stewart
    I'm working on a program in which I want to do something similar to what the Photon Server system does: Offer a common "API" class library, which contains common data classes, enumerations, and interfaces for working with the host program. Have client programs (class libraries) reference this DLL and implement interfaces listed within it. Have the "host" application load built DLL client libraries into separate AppDomains and reference the interfaces that lie within to have polymorphic client code from within a dll file. I have something like this worked out: a class library that contains common code, but I've run into the following question How should I handle static classes? Should I add a method that is called by the host program to synchronize data? How do I keep a static class the same between AppDomains? Should I discard these classes in favor of better interfaces between the code levels? And in general, how do I share data between these loaded AppDomains?

  • Visual Studio - how to create two projects using the same sources

    - by mack369
    My solution consists of 2 executable projects and a couple dlls. Project1 is a Smart Device Project, Project2 is a Windows Forms Project. Both projects use the same libraries, the reason of that is I want to test my libraries on PC before I deploy it on the device. The problem is that the DLL project type can be Smart Device Class Library or Class Library, not both. I cannot add a reference from SD project to WF and vice versa. I was able to add reference from SD project to a dll file (generated from Class Library project) instead of the project itself, but for some reason I got the message "cannot load XXX type from YYY assembly". It doesn't depend on my code, because when I created separate project for the same sources, everything was fine. The only solution I've found is to create 2 types of projects for each library, but I don't know how to make 2 projects based on the same sources.

  • IEnumerable not null but calling Count() results in Exception

    - by Draak
    I have code that's working beautifully on my development machine, but when deployed to the server is throwing null reference exception. So, I can't step through the code, but I've pinned down the culprit. But now I am puzzled. Here's the code. The question is below. Dim certs = From p In persons _ Select New Certificate( _ p.Value, _ New CertificateData.Seminar(thisEvent.Seminar.Name, _ thisEvent.StartDate.Value, _ thisEvent.EndDate.Value, _ thisEvent.Venue.City, _ thisEvent.Venue.State, _ New CertificateData.Instructor( _ staffMember.Name, _ staffMember.Titles, _ instrSignatPath))) _ With {.CertificateId = p.Key} lblMessage.Text = CStr(certs Is Nothing) lblMessage.Text = lblMessage.Text + "<br />" + CStr(certs.Count()) In the code above persons is a dictionary of custom class, and certs is of IEnumerable type. Now here's the quandary.. The first line that sets the label returns False, so certs is not null. But the second line throws an null reference exception. How is this possible?

  • Why wont my .NET 3.5 app run on fresh installation of windows7?

    - by acidzombie24
    In C:\Program Files\Reference Assemblies\Microsoft\Framework i see v3.0 and v3.5. I found that path in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\InstallRoot which also has that path. In C:\Windows\Microsoft.NET\Framework i see versions from 1 to 3.5 My app was built in msvs2010rc1 targeting 3.5. In fact in my project files i see v3.5. So whats with this? Why cant i run it? -edit- The application crashes on double click. With no exception dialog. Ok i see the problem. Sorry guys :$. I hope this post serves as a reference to someone else. I completely forgot that my app uses SDL.NET and i am use to C++ telling me i have forgotten a DLL.

  • ASP.NET Compiles on page load, but not on Ctrl+Shift+B

    - by Steve Syfuhs
    during debug in cassini the code runs fine, but when I explictly build it, the compile breaks on an object saying it can't find the reference. During a breakpoint shows the proper reference to the object, and I can view the debug intellisense. The code itself is simple using CFTW.Controls; ... controls_LatestPresentations c = LoadControl("~/controls/LatestPresentations.ascx") as controls_LatestPresentations; c.loadContent(); return RenderControl(c); The control is a simple user control, with the namespace CFTW.Controls. The calling code is in a webcontrol, which lives in the same folder. I even tried adding the calling code to the same namespace.

  • Iterator category

    - by Knowing me knowing you
    In code: //I know that to get this effect (being able to use it with std algorithms) I can inherit like I did in line below: class Iterator //: public std::iterator<std::bidirectional_iterator_tag,T> { private: T** itData_; public: //BUT I WOULD LIKE TO BE ABLE TO DO IT BY HAND AS WELL typedef std::bidirectional_iterator_tag iterator_category; typedef T* value_type;//SHOULD IT BE T AS value_type or T*? typedef std::ptrdiff_t difference_type; typedef T** pointer;//SHOULD IT BE T* AS pointer or T**? typedef T*& reference;//SHOULD IT BE T& AS reference or T*&? }; Basically what I'm asking is if I have my variable of type T** in iterator class is it right assumption that value type for this iterator will be T* and so on as I described in comments in code, right next to relevant lines. Thank you.

  • Calling web service methods using URLs

    - by Alka
    Hi. So, i have a central web service that is responsible for managing other services. These services register in the main WS with their URL, leading to their own web service. what i need to do now is call the child web services from the central web service. I've searched google on how to do this but all i could find was this. I would like to register any web service and not create a web reference, as suggested in the solution i've found. How is this done without using a web reference?

  • java memory usage

    - by xdevel2000
    I know I always post a similar question about array memory usage but now I want post the question more specific. After I read this article: http://www.javamex.com/tutorials/memory/object_memory_usage.shtml I didn't understand some things: the size of a data type is always the same also on different platform (Linux / Windows 32 / 64 bit)??? so an int will be always 32 bit?; when I compute the memory usage I must put also the reference value itself? If I have an object to a class that has an int field its memory will be 12 (object header) + 4 reference + 4 (the int field) + 3 (padding) = 24 bytes??

  • Map browser DOM using Javascript

    - by EddyR
    I'm trying to map a browsers DOM using javascript. It should list all the functions and attributes associated with it and it should also recurse through any object attributes. Now as I understand it 'window' is the most top-level node (although I've see a reference to 'top' as well in Chrome.) then 'document', etc. However I've never seen 'Node' under 'window' and yet I can call it. So where is 'Node' located? Is there a level above 'window' or is it a separate object (W3C says it's supposed to be inherited by 'document' only.)? I've been playing with a function to do this but I keep getting weird results so I'm not post it here. Alternatively - is it possible to get the properties from the object types instead of the object reference itself? for example 'DOMWindow' instead of 'window'. I think this would stop duplicating data from inherited objects.

  • Why this java application print "true"?

    - by user292084
    This is my first Class Hello.java public class Hello { String name = ""; } This is my second Class Test1.java public class Test1 { public static void main(String[] args) { Hello h = new Hello(); Test1 t = new Test1(); t.build(h); System.out.println((h.name)); } void build(Hello h){ h.name = "me"; } } When I run Test1.java, it prints "me". I think I understand, because of "reference transfer". This is my third Class Test2.java public class Test2 { public static void main(String[] args) { Hello h = null; Test2 t = new Test2(); t.build(h); System.out.println(((h == null))); } void build(Hello h){ h = new Hello(); } } When I run Test2.java, it prints "true", why ? Is it "reference transfer" no longer? I am confused.

  • Is it acceptable to email an Interviewer after the interview?

    - by djhworld
    Yesterday I took part in an interview for a Java position in a company and one of the questions was Does Java pass by reference or by value? In the heat of the moment I (mistakenly) confidently said it passed by reference, possibly because I come from a C/C++ background. Unfortunately after the interview I'd realised my terrible mistake to my horror. So my question is this, is it acceptable for me to wait a few days and drop a quick email to recognise my mistake? Or should I just let this one lie?

  • Resources for memory management in embedded application

    - by Elazar Leibovich
    How should I manage memory in my mission critical embedded application? I found some articles with google, but couldn't pinpoint a really useful practical guide. The DO-178b forbids dynamic memory allocations, but how will you manage the memory than? preallocate everything in advance and send a pointer to each function that needs allocation? Allocate it on the stack? Use a global static allocator (but then it's very similar to dynamic allocation)? Answers can be of the form of regular answer, reference to a resource, or reference to good opensource embedded system for example. clarification: The issue here is not whether or not memory management is availible for the embedded system. But what is a good design for an embedded system, to maximize reliability.

  • Dynamically load a type from an external assembly

    - by Water Cooler v2
    From managed code, how do I load a managed type from another assembly at runtime, assuming the calling code does not have a static reference to the assembly? To clarify, let's say I have class Lib in Lib.cs compiled into Lib.dll. I want to write a class Foo in a separate assembly called Foo.dll, that does not have a reference to Lib.dll statically, but instead loads Lib.dll and then reflects on for the presence of the class Lib and then calls a method on it. Sorry for such an obvious question on Reflection. I figure it'll take much lesser time to get the answer on a forum that to read a few articles.

  • Build Event Macros for Other Projects in the Solution

    - by Adam Driscoll
    Is it possible to reference other projects' properties via a macro within a build event? For example: "Tool1" outputs to directory ..\..\bin\Release "Component1" uses "Tool1" in its post-buildevent To get to "Tool1", "Component1"'s project must do something like $(SolutionDir)bin\Release This requires that Tool1 always output to ..\..\bin\Release. If this is changed this breaks the other project. I know there is no indication to this within the macro list but is there a way to reference another project? Maybe like $(OtherProject.TargetDir)... I know WIX has a similar syntax [$(var.OtherProject.TargetDir)] but I think that may be a different mechanism.
