User Instances (also Known As RANU) Available With SQL Server Express Edition?

Mar 9, 2011

Quoted from http://blogs.msdn.com:

User Instances (also known as RANU) available with SQL Server Express Edition, are NOT RECOMMENDED for hosting environments.I have a server running Server 2008 R2 Web Edition with IIS 7.5 and Sql Server 2008 R2 Express installed.I have only 3 friends as my hosting clients. Each has a restricted Local User Account on the server.What is the drawback of using user instance in production environment?

Edit.Rather than considering the limitation in memory usage and database size that I know, let us consider the user instance only, why isn't it recommended?

Multiple Instances Of Same JQuery Plugin?

Oct 15, 2010

In an aspx page I am calling a jquery plugin for two listboxes as below.

$(document).ready(function() {
$("select.select_AdditionalLanguages").custSelectBox();
$("select.select_Organisations").custSelectBox();
});

[code]...

Managed to solved this issue by having same class name for both the listboxes and then passing both the list box objects to the plugin

$('select.select_field').custSelectBox(null, $('#EditUsers_Organisations'), $('#EditUsers_AdditionalLanguages'));

This might not be the best solution but nothing else worked for me.

Regex Pattern / How To Use Multiple Instances

Mar 7, 2011

YARPQ - Yet Another Regex Pattern Question:

What I am trying to figure out is how to use a custom delimiter, single character or set of characters, to wrap a block of text inside a larger body of text and then pull that text out via regex. I have successfully done this with a single instance of wrapped text. If I have multiple instances, it blows up. Here is an example.

This would be my text block with the internally wrapped text:

[Code]....

When my current regex runs on this block, the greedy nature gives me a match starting with my first wrapped block delimeter and ending with my second wrapped block end delimeter. So my regex of @"#Delim(.*)#EndDelim" doesn't work in this instance. I am trying to figure out how to exclude the #EndDelim from my grouping. Simply using ([^#EndDelim]*) doesn't work as it tells regex to ignore the individual characters inside the brackets and not the actual word so this breaks if I have any of those characters inside my wrapped block of text.

I am probably making this harder than it needs to be. Does anyone know of a good solution or how to ignore entire words in regex?

Share State Between Azure Instances?

Mar 22, 2011

I want to use a global data for MVC web application running on Windows Azure (e.g. something like a list of users having new messages).

For a normal webapp, I could use some per-appdomain storage like AppDomain.SetData or just static variable. What should I use for Azure instead (cache? blob storage? queues?) and what solution would be the fastest one?

Retrieving Multiple Instances Of The Same Session Variable

Mar 16, 2010

I'm having problems with retrieving multiple instances of a session variable from an InProc session state. In the following code I persist a simple BusinessObject into a session variable on the Page_Load event. On the click of a button I try to retrieve the object back into 2 new declared instances of the same BusinessObject. All works great until I change one of the properties in the first instance, it changes the second instance as well. Is this normal behaviour? I would have thought as these were new instances they wouldn't demonstrate static behaviour?

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Not Page.IsPostBack Then
' create a new instance of a business object and set a containg variable
Dim BO As New BusinessObject
BO.SomeVariable = "test"
' persist to inproc session
Session("BO") = BO
End If
End Sub

Protected Sub btnRetrieveSessionVariable_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnRetrieveSessionVariable.Click
' retrieve the session variable to a new instance of BusinessObject
Dim BO1 As New BusinessObject
If Not Session("BO") Is Nothing Then BO1 = Session("BO")
' retrieve the session variable to a new instance of BusinessObject...............................

I have an ASP.NET page inside of an ASP.NET Master page, and inside the page I have two instances of the same web user control.

Multiple ScriptControl Instances Sharing Variable?

Oct 20, 2010

I have a ScriptControl that uses an image as an embedded resource and GetWebResourceUrl to generate the WebResource.axd URL. I am currently using GetScriptDescriptors() to send the URL to the JavaScript object.The ScriptControl can be in a Repeater, so you may have 20+ instances. They all use the same images (not customizable through property), so I would like to set the URL once in a variable and share it. I know I could register a script block with a global variable, but would like to avoid that if possible. Is there a way to set a variable within the scope of the control type (global -> control type -> control instance)?

i am creating a MVC2 application for pubs and bars. I have a model 'Opening_Time' with the following properties:

How/Where is the best place to do this?

Preferably, I want to do it a Model level, so I can use Model.IsValid and the Html.Form helpers

Web Forms :: Can't Have Multiple Instances Of A Custom Validator

Feb 8, 2011

I have the current block of code inside an OnPreRender method of a validator that is inheriting from BaseValidator. If I have one instance of the validator this works fine, but if there are multiple instances the javascript flakes out. As it stands the acutal evaluation function has to be rendered on a per instance basis. I know it's kind of a drop in the bucket, but I'd like to register the block below just once instead of giving each instance a unique key to register with.

How To Make Multiple Web App Instances Read Same File

If more than one person is using the web application, and the web application requires to read a specific file (and in my case, I use StreamReader), I've noticed that the any other instance of the web application would have an exception error when trying to read a file. How do you handle this? And how about when it comes to writing to the same file (if possible)?

Web Forms :: Multiple Instances Of Same User Control On Same Page?

Aug 22, 2010

I have built a User Control in VB which displays two gridviews and allows a user to select an item in the first gridview and display multiple rows in the second grid with the key of the selected item from the first. The data to be displayed is passed to the User Control as a datatable object via a public property of the User Control.

The user control works perfectly, but to allow the the subs in the codebehind of the User Control to access the data set when the user control is initialised, I have declared them as "Private Shared".

Having got everything to work, I now want to display multiple instances of the same User Control with different datasets.

However, because my data objects are defined as "Private Shared" each instance of the user control is overwriting the data of the others.

I can fix this problem by removing the "Shared" keyword, and have also tried setting them to "Protected" instead but then my variables expire after being set and contain "Nothing" when I get to the "RowCommand" event in the Code Behind.

I'm sure I must be doing something stupid, because surely the whole idea of User Controls is to make reusable code drven by parameters.

Here is my code:

Main Program .aspx

[Code]....

Main Program Code Behind

[Code]....

User Control .ascx

User Control Code Behind

Loading (several) Multiple Instances Of Crystal's ReportDocuments In Memory

Aug 25, 2010

I'm having trouble loading (several) multiple instances of crystal's ReportDocuments in memory. Using the following code:

Dim sRPT As New ReportDocument
sRPT.Load("PATHTOMY.RPT")
Dim sRPTs As New List(Of ReportDocument)
For i = 0 To 100
Dim sClone As ReportDocument = sRPT.Clone
sClone.Refresh()
sRPTs.Add(sClone)
Console.WriteLine("RPT Clonado " & i.ToString())
Next

when I reach the 74th instance, the Refresh() call throws a "Report Load failed" exception. Furthermore, the same exception happens even directly calling the .Load(path) method, and affects all ReportDocumetns within the application, regardless the RPT file I'm loading/refreshing.

I'm currently using Crystal XI R2, but testing this code with the v12 assemblies (CR 2008) ended with the same problem. Has anyone ever stumbled with something like this? The reason for all this instances is a report caching for multiple rpt files, per user, and will most likely stay as it is if there is a not-so-nasty workaround for this problema.

.net - Globally Overrride MonthNames For All Instances Of A Specific Culture?

Dec 17, 2010

i have this problem where Microsoft actually got the month names wrong for the Greenlandic culture (kl-GL). I also know that i can pass my own array of string to the DateTimeFormatInfo.MonthNames Property, but it seems like the values i specify is only used in the scope of that one CultureInfo instance. Is there a way to tell .Net that every time i have an instance of the kl-GL culture these specific monthnames should be used?

I know that you can create user specific cultures, but i don't have access to some legacy code to actually change the code to use a my own userspecified culture.
