  • Problem deriving a user control from an abstract base class in website project

    - by Sprintstar
    In a Visual Studio website, I have created a user control. This control is derived from a class (in App_Code) that is itself derived from System.Web.UI.UserControl. This is an abstract class with an abstract method. I then try to implement that method in the user control, but I get the following errors from Visual Studio: Error 1 'WebUserControl.AbstractMethod()': no suitable method found to override C:\Users\User\Documents\Visual Studio 2010\WebSites\Delme\WebUserControl.ascx.cs 10 28 C:\...\Delme\ Error 2 'WebUserControl' does not implement inherited abstract member 'AbstractBaseClass.AbstractMethod()' c:\Users\User\AppData\Local\Temp\Temporary ASP.NET Files\delme\0eebaa86\f1a48678\App_Web_nrsbzxex.0.cs 14 Error 1 says that my override of the abstract method is invalid, it doesn't recognise the abstract method in the base class. Error 2 says that the partial class automatically built by asp.net doesn't implement the abstract method! Note that this works fine when the code is used in a Web Application project. Why is this happening?

  • how to use expressons as function parameters in powershell

    - by rmeador
    This is a very simple task in every language I have ever used, but I can't seem to figure it out in PowerShell. An example of what I'm talking about in C: abs(x + y) The expression x + y is evaluated, and the result passed to abs as the parameter... how do I do that in PowerShell? The only way I have figured out so far is to create a temporary variable to store the result of the expression, and pass that. PowerShell seems to have very strange grammar and parsing rules that are constantly catching me by surprise, just like this situation. Does anyone know of documentation or a tutorial that explains the basic underlying theory of the language? I can't believe these are all special cases, there must be some rhyme or reason that no tutorial I have yet read explains. And yes, I've read this question, and all of those tutorials are awful. I've pretty much been relegated to learning from existing code.

  • How can I center something if I don't know ahead of time what the width is?

    - by zeckdude
    I am trying to center a paragraph tag with some text in it within a div, but I can't seem to center it using margin: 0 auto without having to specify a fixed width for the paragraph. I don't want to specify a fixed width, because I will have dynamic text coming into the paragraph tag and it will always be a different width based on how much text it is. Does anyone know how I can center the paragraph tag within the div without having to specify a fixed width for the paragraph or without using tables?

  • SimpleMembership updating the "isconfirmed" flag

    - by Vijay V
    My Users table (the one that I created) has the following columns: UserId,UserName,FirstName,LastName,DOB After I ran this command WebSecurity.InitializeDatabaseConnection("DefaultConnection", "Users", "UserId", "UserName", autoCreateTables: true); it created the required simple membership tables for me. How would I go about "UnConfirming" an user or setting the "IsConfirmed" flag to false in the webpages_Membership using the new SimpleMembership API? (Earlier, before going to simplemembership using the "Membership" class I could update an user using the api call : Membership.UpdateUser( user );)

  • When are sqlite3 views updated?

    - by John Smith
    I have a database on the iPhone which as a view. When I update the dependent tables the view is not updated. It's only updated when I close and reopen the application. From there onwards things are okay: updates reflect immediately. Is there something I need to do to force update of a VIEW?

  • HTML Encoding with ASP.NET

    - by Corin
    I am currently html encoding all user entered text before inserting/updating a db table record. The problem is that on any subsequent updates, the previously encoded string is reencoded. This endless loop is starting to eat up alot of column space in my tables. I am using parameterized queries for all sql statements but am wondering would it be safe to just let the .NET Framework handle this part without the HTML Encoding?

  • Notifying when screen is off

    - by Al
    I'm trying to generate a notification which vibrates the phone and plays a sound when the screen is off (cpu turned off). According to the Log messages, the notification is being sent, but the phone doesn't vibrate or play the sound until I turn the screen on again. I tried holding a 2 second temporary wakelock (PowerManager.PARTIAL_WAKE_LOCK), which I thought would be ample time for the notification to be played, but alas, it still doesn't. Any pointers to get the notification to run reliably? I'm testing this on an G1 running Android 1.6. Code I'm using: notif.vibrate = new long[] {100, 1000}; notif.defaults |= Notification.DEFAULT_SOUND; notif.ledARGB = Color.RED; notif.ledOnMS = 1; notif.ledOffMS = 0; notif.flags = Notification.FLAG_SHOW_LIGHTS; notif.flags |= NOTIF_FLAGS; //static var if (!screenOn) { //var which updates when screen turns off/on mWakeLock.acquire(2000); } manager.notify(NOTIF_ID, notif);

  • Dump Microsoft SQL Server database to an SQL script

    - by Matt Sheppard
    Is there any way to export a Microsoft SQL Server database to an sql script? I'm looking for something which behaves similarly to mysqldump, taking a database name, and producing a single script which will recreate all the tables, stored procedures, reinsert all the data etc. I've seen http://vyaskn.tripod.com/code.htm#inserts, but I ideally want something to recreate everything (not just the data) which works in a single step to produce the final script.

  • Translate imperative control flow with break-s/continue-s to haskell

    - by dorserg
    Consider the following imperative code which finds the largest palindrome among products of 3-digit numbers (yes, it's the one of the first tasks from "Project of [outstanding mathematician of 18th century]" site): curmax = 0 for i in range(999,100): for j in range(999,100): if ((i*j) < curmax): break if (pal(i*j)): curmax = i*j break print curmax As I'm learning Haskell currently, my question is, how do you translate this (and basically any imperative construct that contains something more complex than just plain iteration, e.g. breaks, continues, temporary variables and all this) to Haskell? My version is maxpal i curmax | i < 100 = curmax | otherwise = maxpal (i-1) (innerloop 999) where innerloop j | (j < 100) || (p < curmax) = curmax | pal p = p | otherwise = innerloop (j-1) where p = i*j main = print $ maxpal 999 0 but this looks like we're still in imperative uglytown. So what could you advise, what are the approaches of dealing with such cases FP-style?

  • Max number of web methods?

    - by Rippo
    Guys I have a web service in asp.net 2.0 that has 234 methods. It seems that when I add another method the site does not compile in VS2005 until I remove one first. I get a message saying that the new method I just added does not exist in a file that belongs in the Microsoft.Net/.../Temporary Files directory. I have restarted IIS, closed down VS2005, removed all files from this temp directory but to no avail. The only way to get the code to compile is to remove another one so as to keep 234 methods.... I can consistency replicate this behaviour so it cannot be my code. Now I know this seems strange but it is true! One other strange thing is that exactly 100 of the method names begin with the word GetXXXyyyZZZ Has anyone else experienced problems with the maximum number of methods that are allowed in a web service? Many Thanks

  • Keeping DB Table sorted using multi-field formula (Microsoft SQL Server)

    - by user298167
    I have a JOB table, with two interesting columns: Creation Date Importance (high - 3, medium 2, low - 1). A JOB record's priority calculated like this: Priority = Importance * (time passed since creation) The problem is, every time I would like to pick 200 jobs with highest priority, and I don't want to resort the table. Is there a way to keep rows sorted? I was also thinking about having three tables one for High, Medium and Low and then sort those by Creation Date.

  • Is there a way to add extra fields to an association in the ADO.NET Entity Framework?

    - by bigbird1040
    I would like to be able to model a many-to-many relationship that has extra details about the relationship. For example: Person: int id, String name Project: int id, String name ProjectPerson: Person.id, Project.id, String role Whenever I create the ProjectPerson association in the EF, I am unable to add the role attribute to the association. If I create the tables in my DB and then import it into the model, I lose the extra properties.

  • Can you create a HIPAA compliant Amazon S3 Web Application?

    - by xkingpin
    I am facing some questions when trying to design an S3 application using ASP.NET MVC and trying to stay HIPAA compliant. My initial plan was to require an SSL connection to my web server, encrypt the images on my server, then send them to s3 using my private keys. Here's my obvious concerns: You cannot store unencrypted images in any temporary file cache when client views images within the browser. Even if I setup an ashx to generically handle the image in memory, couldn't this get stored in cache? Saying the images will be encrpyted because you will be connecting to my server via https still does not guarantee all browsers will not cache data. It's not possible to even consider the "Query String" with expiration option since data will be encrypted before being stored on disk at s3, and will again be decrypted at my server in memory. I think my only option would be to write/purchase some sort of ActiveX component that will not expose the image as a simple html image source or write my app as a client side WinForm application.

  • Basic Database Design

    - by Thurein
    Hi, This question would be a bit childish, I have three tables, users, usergroups and contacts. In my system, the end user can create a contact and subsequently he\she may define the visibility of the contact by setting only for that user, or for a set of users or a set of usergroups. So I am wondering, how my database design would be, it should be many to many between users and contacts or many to many between usergroups and contacts. Definitely there is a one to many relationship between users and usergroups. Thanks Thurein

  • How can I make a web-based "table" select like a spreadsheet? (rectangular area vs row-wrap selecti

    - by Dax
    I want to make a table that displays on a webpage, but one requirement is to make it easy to copy and paste into a spreadsheet. Normal HTML tables selection behavior is obviously different from how a spreadsheet like Excel selects -- when you select multiple rows it wraps around instead of selecting a rectangular area. Is there any way to make HTML table behave like a spreadsheet in this regard, or is the only way to resort to a Flash table or something similar?

  • how to insert based on the date

    - by Gaolai Peng
    I have a table table1 (account, last_contact_date, insert_date), account and last_contact_date are primary keys. The insert_date is set with the time the recored being added by calling getdate(). I also have a temporary table #temp(account, last_contact_date) which I use to update the table1. Here are sample data: table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 #temp account last_contact_date 1 2012-09-27 2 2012-09-27 3 2012-08-01 The result table depends on the inserting date. If the date is 2012-09-28, the result will be table1 account last_contact_date insert_date 1 2012-09-27 2012-09-28 2 2012-09-27 2012-09-28 3 2012-09-01 2012-09-28 If the date is 2012-09-29, the result will be table1 account last_contact_date insert_date 1 2012-09-01 2012-09-28 2 2012-09-01 2012-09-28 3 2012-09-01 2012-09-28 1 2012-09-27 2012-09-29 2 2012-09-27 2012-09-29 Basically the rule is (1) if the inserting date is the same day, i will pick the lastest last_contact_date, otherwise, (2) if the last_contact_date is later than the current last_contact_date, I will insert a new one. How do I write a query for this insert?

    Looking for example code that uses semantic HTML that I can use to test stylesheets with. The version/doctype is unimportant though HTML5 would be great. When I say "comprehensive" - I am looking for use of definition lists, forms, tables, plus all the usual. Thanks
