  • Detect session hang and kill it

    - by Jack Juiceson
    Hi all, I have an asp.net page that runs certain algorithm and returns it's output. I was wondering what will happen and how to handle a case where the algorithm due to a bug goes into infinite loop. It will hog the cpu and other sessions will be served very slowly. I would love to have a way to tell IIS, if processing Algo.aspx takes more than 5 seconds, kill it or something like that. Thanks in advance

  • How to give user confirmation message before ActionLink based on validation

    - by RememberME
    I have the following link. On click, I'd like to check the item.primary_company field and if populated, give the user a warning and ask if they would like to continue. How can I do this? <a href="<%= Url.Action("Activate", new {id = item.company_id}) %>" class="fg=button fg-button-icon-solo ui-state-default ui-corner-all"><span class="ui-icon ui-icon-refresh"></span></a> EDIT I've changed to this, but nothing happens when clicked. Also, I don't know how to reference the item to do the check on the primary_company field. I only want to message to show if item.primary_company.HasValue. I'd also like to show item.company1.company_name in the confirm message. <a href="#" onclick="return Actionclick("<%= Url.Action("Activate", new {id = item.company_id}) %>");" class="fg=button fg-button-icon-solo ui-state-default ui-corner-all"><span class="ui-icon ui-icon-refresh"></span></a> <script type="text/javascript"> function Actionclick(url) { alert("myclick"); if ( confirm("Do you want to activate this company's primary company and all other subsidiaries?")) { location.href(url); } }; </script>

  • How to style "form" field labels in Windows Phone 7?

    - by Jeremy Bell
    Is there any standards guidance on how to style field labels next to form fields in windows phone 7 silverlight applications? For example, let's say I have a StackPanel with the TextBlock label and a TextBox for data entry. Currently I am using the default TextBlock Margin included in the PhoneTextSubtleStyle ("12,0,12,0"), and using a Margin of "0,-12,0,0" to push the TextBox up closer to the label: <StackPanel HorizontalAlignment="Left"> <TextBlock VerticalAlignment="Center" Text="Name" Style="{StaticResource PhoneTextSubtleStyle}" /> <TextBox Text="{Binding ItemName, Mode=TwoWay}" TextChanged="TextBox_TextChanged" VerticalAlignment="Center" Width="433" Margin="0,-12,0,0" /> </StackPanel> Note that the TextBox seems to have some internal padding of 12 pixels to the left and right, so that the TextBlock label and the TextBox control visually line up perfectly on the left. The problem is, I see existing apps with widely varying conventions for field label styling. Some do not do the negative margin adjustment, like I have above. Some don't. Some appear to override the label TextBlock Margin so that it is indented an additional 12 pixels on the left (i.e. "24,0,12,0" instead of the default "12,0,12,0"). Some apps put the labels to the left of the fields themselves (I hate that). Is there some standard design guidance on field labels in Windows Phone 7? I read through the design template PDF and could only determine that the field labels should be upper case on the first word (preferably only one word labels), and should NOT have a colon at the end. I didn't see anything with regards to margins or alignment between the label and the field.

  • SSIS Permissions issue

    - by Dave
    Hi All, How can we set permissions for users to only allow them to download SSIS packages from the production server and but deny them permissions to run any package in the Server. http://msdn.microsoft.com/en-us/library/ms141053(SQL.90).aspx If i assign users to any of the DB roles db_dtsadmin, db_dtsltduser, and db_dtsoperator they will automatically have permission to run the package. Appreciate your inputs. Thanks!

  • Why can't I create an abstract constructor on an abstract C# class?

    - by Anthony D
    I am creating an abstract class. I want each of my derived classes to be forced to implement a specific signature of constructor. As such, I did what I would have done has I wanted to force them to implement a method, I made an abstract one. public abstract class A { abstract A(int a, int b); } However I get a message saying the abstract modifier is invalid on this item. My goal was to force some code like this. public class B : A { public B(int a, int b) : base(a, b) { //Some other awesome code. } } This is all C# .NET code. Can anyone help me out? Update 1 I wanted to add some things. What I ended up with was this. private A() { } protected A(int a, int b) { //Code } That does what some folks are saying, default is private, and the class needs to implement a constructor. However that doesn't FORCE a constructor with the signature A(int a, int b). public abstract class A { protected abstract A(int a, int b) { } } Update 2 I should be clear, to work around this I made my default constructor private, and my other constructor protected. I am not really looking for a way to make my code work. I took care of that. I am looking to understand why C# does not let you do this.

  • How do I cast from int to generic type Integer?

    - by Rob Kent
    I'm relatively new to Java and am used to generics in C# so have struggled a bit with this code. Basically I want a generic method for getting a stored Android preference by key and this code, albeit ugly, works for a Boolean but not an Integer, when it blows up with a ClassCastException. Can anyone tell me why this is wrong and maybe help me improve the whole routine (using wildcards?)? public static <T> T getPreference(Class<T> argType, String prefKey, T defaultValue, SharedPreferences sharedPreferences) { ... try { if (argType == Boolean.class) { Boolean def = (Boolean) defaultValue; return argType.cast(sharedPreferences.getBoolean(prefKey, def)); } else if (argType == Integer.class) { Integer def = (Integer) defaultValue; return argType.cast(sharedPreferences.getInt(prefKey, def)); } else { AppGlobal.logWarning("getPreference: Unknown type '%s' for preference '%s'. Returning default value.", argType.getName(), prefKey); return defaultValue; } } catch (ClassCastException e) { AppGlobal.logError("Cast exception when reading pref %s. Using default value.", prefKey); return defaultValue; } } I've tried various ways - using the native int, casting to an Integer, but nothing works.

  • MSSQL Server using multiple ID Numbers

    - by vincer
    I have an web application that creates printable forms, these forms have a unique number on them, the problem is I have 2 forms that separate numbers need to be created for them. ie) Form1- Numbered 2000000-2999999 Form2- Numbered 3000000-3999999 dbo.test2 - is my form information table Tsel - is my autoinc table for the 3000000 series numbers Tadv - is my autoinc table for the 2000000 series numbers What I have done is create 2 tables with just autoinc row (one for 2000000 series numbers and one for 3000000 series numbers), I then created a trigger to add a record to the coresponding table, read back the autoinc number and add it to my table that stores the form information including the just created autoinc number for the right series of forms. Although it does work, I'm concerned that the numbers will get messed up under load. I'm not sure the @@IDENTITY will always return the right value when many people are using the system. (I cannot have duplicates and I need to use the numbering form show above. Thanks for any help See code below. ** TRIGGER ** CREATE TRIGGER MAKEANID2 ON dbo.test2 AFTER INSERT AS SET NOCOUNT ON declare @someid int declare @someid2 int declare @startfrom int declare @test1 varchar(10) select @someid=@@IDENTITY select @test1 = (Select name1 from test2 where sysid = @someid ) if @test1 = 'select' begin insert into Tsel Default values select @someid2 = @@IDENTITY end if @test1 = 'adv' begin insert into Tadv Default values select @someid2 = @@IDENTITY end update test2 set name2=(@someid2) where sysid = @someid SET NOCOUNT OFF

  • In RoR, is there an easy way to prevent the view from outputting <p> tags?

    - by dt
    I'm new to Ruby and Rails and I have a simple controller that shows an item from the database in a default view. When it is displaying in HTML it is outputting <p> tags along with the text content. Is there a way to prevent this from happening? I suppose if there isn't, is there at least a way to set the default css class for the same output in a statement such as this: <% @Items.each do |i| %> <%= i.itemname %> <div class="menu_body"> <a href="#">Link-1</a> </div> <% end %> So the problem is with the <%= i.itemname %> part. Is there a way to stop it from wrapping it in its own <p> tags? Or set the css class for the output? Thanks!

  • Is this a good way to generically deserialize objects?

    - by Damien Wildfire
    I have a stream onto which serialized objects representing messages are dumped periodically. The objects are one of a very limited number of types, and other than the actual sequence of bytes that arrives, I have no way of knowing what type of message it is. I would like to simply try to deserialize it as an object of a particular type, and if an exception is thrown, try again with the next type. I have an interface that looks like this: public interface IMessageHandler<T> where T : class, IMessage { T Handle(string message); } // elsewhere: // (These are all xsd.exe-generated classes from an XML schema.) public class AppleMessage : IMessage { ... } public class BananaMessage : IMessage { ... } public class CoconutMessage : IMessage { ... } Then I wrote a GenericHandler<T> that looks like this: public class GenericHandler<T> : IMessageHandler<T> where T: class, IMessage { public class MessageHandler : IMessageHandler { T IMessageHandler.Handle(string message) { T result = default(T); try { // This utility method tries to deserialize the object with an // XmlSerializer as if it were an object of type T. result = Utils.SerializationHelper.Deserialize<T>(message); } catch (InvalidCastException e) { result = default(T); } return result; } } } Two questions: Using my GenericHandler<T> (or something similar to it), I'd now like to populate a collection with handlers that each handle a different type. Then I want to invoke each handler's Handle method on a particular message to see if it can be deserialized. If I get a null result, move onto the next handler; otherwise, the message has been deserialized. Can this be done? Is there a better way to deserialize data of unknown (but restricted) type?

I thought it'd be possible by defining a new permission level in: http://servername/_layouts/addrole.aspx ('Add a permission level' page) However, when you select the "add items" list permission, "view items" is automatically ticked also.
