  • Global Error Handling for Web Services

    - by jusaskin
    I have a web project consisting of only web services. I need a global way of handling errors on the server so I can send emails, log in event log, etc. Global.asax doesn't work according to MSDN. How should I go about this? I have tried creating a soapExtension, but it is never hit.

  • C# and Objects/Classes

    - by user1192890
    I have tried to compile code from Deitel's C# 2010 for programmers. I copied it exactly out of the book, but it still can't find main, even though I declared it in one of the classes. Here is a look at the two classes: For GradeBookTest: // Fig. 4.2: GradeBookTest.cs // Create a GradeBook object and call its DisplayMessage method. public class GradeBookTest { // Main method begins program execution public static void Main(string[] args) { // create a GradeBook object and assign it to myGradeBook GradeBook myGradeBook = new GradeBook(); // call myGradeBook's DisplayMessage method myGradeBook.DisplayMessage(); } // end Main } // end class GradeBookTest Now for the GradeBook class: // Fig. 4.1: GradeBook.cs // Class declaration with one method. using System; public class GradeBook { // display a welcome message to the GradeBook user public void DisplayMessage() { Console.WriteLine( "Welcome to the Grade Book!" ); } // end method DisplayMessage } // end class GradeBook That is how I copied them. Here is how they appeared in the book: 1 // Fig. 4.2: GradeBookTest.cs 2 // Create a GradeBook object and call its DisplayMessage method. 3 public class GradeBookTest 4 { 5 // Main method begins program execution 6 public static void Main( string[] args ) 7 { 8 // create a GradeBook object and assign it to myGradeBook 9 GradeBook myGradeBook = new GradeBook(); 10 11 // call myGradeBook's DisplayMessage method 12 myGradeBook.DisplayMessage(); 13 } // end Main 14 } // end class GradeBookTest and // Fig. 4.1: GradeBook.cs // Class declaration with one method. using System; public class GradeBook { // display a welcome message to the GradeBook user public void DisplayMessage() { Console.WriteLine( "Welcome to the Grade Book!" ); } // end method DisplayMessage } // end class GradeBook I don't see why they are not working. Right now I am using Visual Studio Pro 2010. Any Thoughts?

  • JsonIgnore attributes not working in ASP.NET?

    - by Geoffrey
    I've got an object in my project with circular references. I've put [JsonIgnore] above the field like so: [JsonIgnore] public virtual Foobar ChildObject { get; set; } I'm still getting circular reference errors when I serialize the object. The only fields that do not have JsonIgnore are string fields and should not cause this. Is there something else I need to do to get JsonIgnore to work? Thanks!

  • Issuing multiple requests using HTTP/1.1 Pipelining

    - by Robert S. Barnes
    When using HTTP/1.1 Pipelining what does the standard say about issuing multiple requests without waiting for each request to complete? What do servers do in practice? I ask because I once tried writing a client which would issue a batch of GET requests for multiple files and remember getting errors. I wasn't sure if it was due to me incorrectly issuing the GET's or needing to wait for each individual request to finish before issuing the next GET.

  • easy hex/float conversion

    - by yeus
    I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link: http://docs.python.org/library/stdtypes.html#additional-methods-on-float Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes... thx for the answers!

  • Facebook connect with iPhone not working?

    - by Atulkumar V. Jain
    Hi Everybody, I am trying to use Facebook connect in my application, but its not working as I desire. When I am trying to use the API Key and the API SecretKey of my application which I have registered with the facebook its not working. I have downloaded the code for the facebook. In the SessionViewController.m file when I pass my key values its not working. What I am trying to achieve is, when the app launches the first page is the Facebook Login Page. The user enters his username and password and then the next view should display. But nothing is happening, even the label doesn't display the username. Heres the code which I am using - (void)request:(FBRequest*)request didLoad:(id)result { NSArray* users = result; NSDictionary* user = [users objectAtIndex:0]; NSString* name = [user objectForKey:@"name"]; _label.text = [NSString stringWithFormat:@"Logged in as %@",name]; NSLog(@"Username is :- %@",name); FrontController *main = [[FrontController alloc] init]; [self.view addSubview:main.view]; [main release]; } I am not able to figure out what is wrong with this code. When I try with some other key values such as the key for connect application its working fine. Can anyone help me with this... Thanx in advance...

  • Good C++ Debugging/IDE Environment for Linux?

    - by Brandon Pelfrey
    I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

  • Lite-Javascript Gallery - Can I position the img absolutely in relationship to the lis?

    - by blackessej
    I have a lite-javascript run image gallery. The javascript grabs each element in the list and places it as a background in the parent element. Then the CSS styles the thumbnails as small blocks with a defined height/width. A click-event for each object toggles it’s child’s element’s visibility and adds an “active” class name to the . Using CSS, I'm trying to place the absolutely to make it appear at the same position for each thumb, but it's moving in relation to the thumbs. Here's the CSS: #jgal li { background-position:50% 50%; background-repeat:no-repeat; border:solid #999 4px; cursor:pointer; display:block; float:left; height:60px; width:60px; margin-bottom:14px; margin-right:14px; opacity:0.5; } #jgal li img { position:absolute; top:0px; left:210px; display:none; } And the site: http://www.erisdesigns.net Thanks in advance for any help!

  • CodeIgniter: Where should a particular functionality go ?

    - by Samnan
    I have an application in codeigniter and a page needs to perform the following tasks 1 - controller decides which model to use based of the url and parameters 2 - controller loads the model and get the data from it 3 - controller formats the data in a particular format, depending on the items in it 4 - controller loads a common view, which will display the data (formatted data contains simple display fields) now there is a search page, which needs to do a text query against all of the possible text fields in database in all tables. It needs to show each type of data in its own formatted output on a single page as a list. The problem: The search controller can do the search, dynamically load model for each record type, and get the data from model. Problem comes when the data needs to be formatted. It looks that ideally the search controller should load another controller which will provide formatted data ... There is where it gets out of control ... My question is: What am I doing wrong? Is there any better way to do this? How would you do the same to solve the problem?

  • Large Product catalog with statistics - alternatives to Sql Server?

    - by Eric P
    I am building UI for a large product catalog (millions of products). I am using Sql Server, FreeText search and ASP.NET MVC. Tables are normalized and indexed. Most queries take less then a second to return. The issue is this. Let's say user does the search by keyword. On search results page I need to display/query for: First 20 matching products (paged, sorted) Total count of matching products for paging List of stores only of matching products List of brands only of matching products List of colors only of matching products Each query takes about .5 to 1 seconds. Altogether it is like 5 seconds. I would like to get the whole page to load under 1 second. There are several approaches: Optimize queries even more. I already spent a lot of time on this one, so not sure it can be pushed further. Load products first, then load the rest of the information using AJAX. More like a workaround. Will need to revise UI. Re-organize data to be more Report friendly. Already aggregated a lot of fields. I checked out several similar sites. For ex. zappos.com. Not only they display the same information as I would like in under 1 second, but they also include statistics (number of results in each category). The following is the search for keyword "white" http://www.zappos.com/white How do sites like zappos, amazon make their results, filters and stats appear almost instantly?

  • Detect if any USB drive is detected or not using WinForm Application

    - by Pavan Kumar
    I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.
