    i need a dropdownlist to show current month and year (January 2010) till January 2011, and an additional record of January 2011 +. But I want to save this in the database as 01/01/2010 format. also if the user selects current month then the record should be getdate() to go in database, else for any other month it should be 02/01/2010 (date = 01, first day of month). how do i do this in aspx.vb .net. i wrote a function to populate the dorpdownlist - Public Sub Load_dates(ByRef DDL As System.Web.UI.WebControls.DropDownList) Try Dim i As Integer Dim j As Integer For i = Now.Year To Now.Year For j = Now.Month To Now.Month + 11 DDL.Items.Add((j.ToString) + " " + (i.ToString)) Next Next Catch ex As Exception ReportError(ex) End Try End Sub this function only shows number like 01 2010 and 02 2010. how can i format this to show january 2010 and february 2010 and so on. please advice

  • Use backups if unavailable (not just down)

    - by PriceChild
    Using haproxy, I want: A pool of 'main' servers and 'backup' servers, though they don't necessarily have to be in separate pools. Each backend has a low 'maxconn' (in this case 1) Clients should not wait in a queue. If there are no immediately available servers in the 'main' pool they should be shunted to the 'backup' pool without delay. Right now I have one backend, 'main' servers have an absurdly high weighting and it 'works'. acl use_backend + connslots is along the right lines but without the patch in my own answer it isn't perfect. Bonus points for not requiring a modified haproxy binary.

  • How do i get (is it possible to) a reference to the class that creates an instance of another class.

    - by Cadde
    Odd situation... I need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor. The solution i am looking for is something like this: Public Class ChildClass Public Sub New(args) _MyMember = GetMemberFromCallingClass() ... ... End Sub End Class I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass. Is this possible and if so, what should i look at to make this part of my code.

  • regex no character

    - by iamnotmad
    In this text: warning here there are several types of warnings in this string warning.gif at the end warning end of line warning I want to match every warning except warning.gif. I cannot seem to get it to include the last one that has no character (control or otherwise) after it. using warnings?[^\.] gets what I want except for the last warning (on the last line). I think because there is no character at all after. How can I get it to include that one?

  • Is there a way I can find if my hard disk data was stolen? [closed]

    - by Bridget
    How can I tell if the repair shop stole my hard drive? I had my computer in the shop for a couple of days to get a diagnostic check and he quoted me $130. I have a family member who said he would do it for $30 so I rejected the offer and requested it back. When he returned it I hooked it back up and now I get a low disk space warning; when I dropped it off I had at least 50 gb of space left, on a total of 149 gb and all my pictures movies, and music are gone. Can I find if he indeed did steal my hard drive or something?

  • Preserving NULL values in a Double Variable

    - by Sam
    Hi, I'm working on a vb.net application which imports from an Excel spreadsheet. If rdr.HasRows Then Do While rdr.Read() If rdr.GetValue(0).Equals(System.DBNull.Value) Then Return Nothing Else Return rdr.GetValue(0) End If Loop Else I was using string value to store the double values and when preparing the database statement I'd use this code: If (LastDayAverage = Nothing) Then command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", System.DBNull.Value) Else command.Parameters.AddWithValue("@WF_LAST_DAY_TAG", Convert.ToDecimal(LastDayAverage)) End If I now have some data with quite a few decimal places and the data was put into the string variable in scientific notation, so this seems to be the wrong approach. It didn't seem right using the string variable to begin with. If I use a double or decimal type variable, the blank excel values come across as 0.0. How can I preserve the blank values? Thanks

  • Forcing driver to device match

    - by shodanex
    I have a piece of usb hardware, for which I know the driver. However, the vendor id and product id do not match the VID, PID pair registered in the driver. Is there a way in linux to force a driver to be associated with a known device, that do not involve kernel module recompilation to add a PID / VID pair ?

  • Apache Connection vs. Request

    - by user101570
    I apologize in advance if this is a basic question, but I am quite confused after reading the Apache documentation and other tutorials. Does a single Apache prefork process serve all HTTP requests for a given client? That's what I thought, but when I reduce maxclients down to a low number, my page load times go to a crawl. This despite the fact I'm the only client on the server in question. This would suggest each process serves a single HTTP request at a time, rather than serving all requests within the TimeOut window. So if a single webpage requires 15 HTTP requests to load fully, do I require 15 prefork Apache processes to optimally serve it?

  • Perform tasks with delay, without delaying web response (ASP.NET)

    - by Tomas Lycken
    I'm working on a feature that needs to send two text messages with a 30 second delay, and it is crucial that both text messages are sent. Currently, this feature is built with ajax requests, that are sent with a 30 second javascript delay, but since this requires the user to have his browser open and left on the same page for at least 30 seconds, it is not a method I like. Instead, I have tried to solve this with threading. This is what I've done: Public Shared Sub Larma() Dim thread As New System.Threading.Thread(AddressOf Larma_Thread) thread.Start() End Sub Private Shared Sub Larma_Thread() StartaLarm() Thread.Sleep(1000 * 30) StoppaLarm() End Sub A web handler calls Larma(), and StartaLarm() and StoppaLarm() are the methods that send the first and second text messages respectively. However, I only get the first text message delivered - the second is never sent. Am I doing something wrong here? I have no deep understanding of how threading works in ASP.NET, so please let me know how to accomplish this.

  • NSString inheritance

    - by Stef
    Hi, I'm doing an useless thing for my first step in Obj-C @interface String : NSString { int m_isnull; } - (id) init; - (int) isNull; @end @implementation String - (id) init { self = [super init]; m_isnull=1; return self; } - (int) isNull { return m_isnull; } @end test : String *a; a=@"ok"; Works fine, but just 2 little questions 1) When I'm compiling I have this warning warning: incompatible Objective-C types assigning 'struct NSString *', expected 'struct String *' I don't know how to avoid it !? 2) a=@"ok" is a fastest way to initialize a string, but when I'm debugging, I don't stop by at my init constructor why ?

  • What Design Pattern To Replace 'CurrentStep' Variable

    - by Rob P.
    Tried to search but didn't know how to phrase it. I've got some code that is essentially... Private CurMajorStep as Integer = 0 Private CurMinorStep as Integer = 0 Public Sub PerformNextStep() Select Case iMajorStep Case 0 ThingOne() Case 1 ThingTwo() Case 2 ThingThree() Case 3 ThingFour() Case 4 AnythingElse() Case 5 Finish() End Select End Sub And then, in some of those, the CurMinorStep keeps track of the current state of that particular 'step'. I hope that all makes sense. The code is messy and I know it's going to be problematic to maintain. Can someone point me to a clean OO pattern to handle this?

  • How to use Joomla to allow users to create/update data on my site?

    - by gromo
    Right now Im using an extension called chronoforms but Im open to anything that works. I can make forms just fine, and it saves the submitted data to a table. Where I am stuck is, how do I then allow my front end users who filled out and submitted the form to go back, view their old answers, change them, and resubmit them or resave them. In order to do this I think I would need to be able to retrieve their last answers from the table on which it is stored, replug the last specific data record for that user only back into the original form on the front end and let the user change and resubmit it? Unless there is a better way to allow the user to change their answers to a form and resave them? If anyone knows how to do this, or if there is a better way I should be going about doing this, (perhaps there is another extension that handles this kind of thing) please let me know. Thanks!

Software/hardware solutions are welcome! Thanx :)

  • How can i pass nothing or a blank cell to an Optional argument in VBA?

    - by user2985990
    I am trying to set up a function so that whether I pass a blank cell or do not even select a cell for the argument it returns the function I am looking for. Here is my code: Function FinancialsAge(FirstBirthday As Date, BeginningDate As Date, Optional Second Birthday As Variant) As String If IsMissing(SecondBirthday) = True Or SecondBirthday = vbNullString Then FinancialsAge = Year(BeginningDate - FirstBirthday) - 1900 ElseIf SecondBirthday Then FinancialsAge = (Year(BeginningDate - FirstBirthday) - 1900) & "/" & (Year(BeginningDate - SecondBirthday) - 1900) End If End Function This code works fine as long as I select a blank cell for the third argument but when I leave the third argument out I get a "#Value!" error in the cell. Anyway to do this in Excel VBA so that the function works under both circumstances? Thanks,

  • Include only the latest/newest associated record with active record?

    - by railsnewbie
    is it possible to load only the latest associated record of an associated table? an example: class author attr_accessible :first_name, :last_name, :birthday has_many :books end class book attr_accessible :pages, :date of publication, :title belongs_to :author end Is there a way to generate a scope to load only the newest released book the author wrote? Or the book with the most pages? I know, that I could include or join all books. But I don't know if its possible to load only a specific book for each author. So that I could do a query like this: Author.authors_and_their_newest_book So that I could get these results first_name_author_1, last_name_author_1, birthday_author_1, pages_book_3, date of publication_book_3, title_book_3 first_name_author_2, last_name_author_2, birthday_author_2, pages_book_5, date of publication_book_5, title_book_5 first_name_author_3, last_name_author_3, birthday_author_3, pages_book_9, date of publication_book_9, title_book_9 ...

  • How are builds deployed into QA->Staging->Production for ASP.NET Web Applications?

    - by CodeToGlory
    Secondary questions are How do we best utilize SCM in the build process? How are code files labed and branched? Should we the .csproj and .sln files for build? How flexible are these when deploying to several environments? I know these are msbuild files. But as we add new files, this can become a bottlenect of updating and maintaining these .csproj files in SCM. How is rollback done in case of failed builds that QA missed testing etc,etc., Are there any good articles on the build process? This is more a question on the process and less on the choice of automated build tools. Please share your build process. I would like to get an end-to-end view from developers checking-in to Going Live.

  • Alert Box Running First?

    - by corymathews
    I have some jQuery/JS below. The first thing to run is the alert box at the end. $(document).ready(function() { $("#id1 img , .msg").stop().animate( { width: '300px', height: '300px'}, { duration: 'slow', easing: 'easeInSine' }).pause(3000); $(".msg").animate( { width: '50px', height: '50px' }, { duration: 498, easing: 'easeOutSine' }); $("#id1 img").animate( { width: '50px', height: '50px' }, { duration: 500, easing: 'easeOutSine' }); $("#id1 img , .msg").animate( { width: '300px',height: '300px'}, { duration: 'slow', easing: 'easeInSine' }).pause(3000); alert('eh?'); }); I do have a easing plugin. If I run this the alert will show, and then the first animate will happen in the background but not be shown. It will just appear at the final size. Shouldn't the alert run at the end of all the animation? Can anyone explain why this is happening?

  • $.ajax + authentication + `@` in username

    - by Koning Baard XIV
    I am creating a web app which uses jQuery to authenticate: $.ajax({ url: "/session/create?format=json", type: "GET", dataType: "json", cache: false, username: $("#signin-email").val(), password: $("#signin-password").val(), success: function(data) { if(data.success) { success = true; } } }); The problem is that the code only makes the AJAX-request when the username does not include things like an @, which is required in my app. Can anyone help me with how I can do this? I do not mind changing the back-end a little bit, but requiring users to have an @-less email is not an option. Oh, my back-end is a Ruby-on-Rails app

  • Problem building relationships between models

    - by Brian Roisentul
    Until now, I've been using acts_as_taggable_on plugin for tagging announcements. That plugin creates the following tables: taggings: relates tags and announcements table(for the tagged item, it has a field called taggable_id, which I rename to "announcement_id" for what I'll explain below). tags: has the tag ids and names. The other day, I discovered that I had no way of getting the announcements tagged with a certain tag, but doing Announcement.tagged_with(tag_name), and I don't want to search by name, but for id. So, as I'm using almost nothing of the functionality in that plugin, I decided to create the models for taggings and tags tables, to accomplish this: Announcement.tags. The models' relationships look as following: class Tagging < ActiveRecord::Base belongs_to :announcement belongs_to :tag end class Tag < ActiveRecord::Base has_many :announcements, :through => :taggings end class Announcement < ActiveRecord::Base has_many :tags, :through => :taggings Why can't I execute the command Announcement.tags? Because when I try, I get undefined method `tags'

  • Performance impact of running Linux in a virtual machine in Windows?

    - by vovick
    Hello, I'd like to know what performance impact I could expect running Linux in a virtual machine in Windows. The job I need Linux for is heavy and almost non-stop code compilation with GCC. Dual-boot doesn't look like a very attractive solution, so I'm counting on low VM overhead right now (10-20% would be fine for me, but 50% or more will be unacceptable). Did anyone try to measure the performance difference, are there any comparison tables? What virtual machine with the lowest overhead possible will you suggest? My host OS is Win7 and I've got a modern Core i7 with VT-x present. Thanks!
