RemoveAll Is Also Changing Previously Cached Data That It Should Not Be Able To Change?

Apr 28, 2011

This has been driving me insane all day and I think I have the problem narrowed down, but it just doesn't make sense how it could be happening. I have 2 public shared functions and 2 private shared functions. One provides a list of custom objects and one filters the objects based on some parameters in the function call. Both return List(of custom object). The 2 private shared functions are the predicate functions used in the List(of t).RemoveAll function.

[Code]...

Now, the next time I call the GetItemList function it only returns 50 item objects, not the 100 item objects that it should be returning due to the cache being set! I have verified this in the debugger and by running many, many different tests to see what combinations of parameters may be causing the problem. In my testing, as soon as one of the .RemoveAll functions is used the GetItemList item list will get set to whatever the NarrowItemList function returned.

Even if the cache wasn't being set correctly, shouldn't it just get the data again from the database and return 100 items again? What could I be missing???

Syntax To Change The Value Of A Cached Object Property?

Jun 6, 2010

In an ASP.NET 3.5 VB web app, I successfully manage to cache an object containing several personal details such as name, address, etc. One of the items is CreditNum which I'd like to change in the cache on the fly. Is there a way to access this directly in the cache or do I have to destroy and rebuild the whole object just to change the value of objMemberDetails.CreditNum?The cache is set using:

Public Shared Sub CacheSet(ByVal key As String, ByVal value As Object)
Dim userID As String = HttpContext.Current.User.Identity.Name
HttpContext.Current.Cache(key & "_" & userID) = value
End Sub

Fastest Alternative To Datatable.Select To Narrow Cached Data?

Sep 28, 2009

I have a search function on my company's website (based on .NET 2.0) that allows you to narrow the product catalog using up to 9 different fields. Right now, after you make your selections on the frontend I am building a dynamic query and hitting the database (SQL Server) to get the resulting list of items numbers. I would like to move away from hitting the database everytime and do all of this in memory for faster results. Basically a 3500 - 4500 row "table" with 10 columns: the item number (which could be a primary key) and the 9 attribute fields (which have repeating values for many many rows).

There can be any number of different searches between the 9 columns to get the items you want:
Column A = 'foo' AND Column D = 'bar'
Column B = 'foo' AND Column C = 'bar' AND Column I = 'me'
Column H = 'foo'
etc...

Based on my research, the .Select() function seems like the slowest way to perform the search, but it stands out to me as being the quickest and easiest way to perform the narrowing searches to get the list of item numbers:
MyDataSet.Select("Column B = 'foo' AND Column E = 'bar' AND Column I = 'me'")
In my specific case, what method I use as an alternative that has the same narrowing functionality and better performance instead of settling for the datatable.select() method?

Refresh Page Back To Gridview Data At Previously?

Jul 29, 2009

I have three dropdown list boxes and a gridview. The gridview shows data based on what is entered in the dropdown list boxes. I have added a button that allows the user to insert a record into the database and then the page refreshes. The problem is that when the page refreshes the gridview goes back to whatever was initially in the dropdown list boxes when I first brought up the page. Is there a way to refresh and maintain the data in the list boxes so the gridview shows the same data? My code is below.

.net - Using .Contains Method With Cached Hashset

Jul 26, 2011

I know that the .Contains method on a hashset is fast. My question is what is the best method for getting the hashset data before repetitively using the .Contains method?

I can think of 2 options. Both of these examples would be called in a loop of undetermined length.

1) Call the method that returns the cached hashset directly and use the .Contains method.

IF (GetHashSetMethod.Contains("TESTVALUE") THEN BLAH, BLAH, BLAH...

2) Create a new hashset outside of the loop and load the cached hashset data into it so the method that returns the hashset is only called once, then use the .Contains method.

DIM HashTest AS HASHSET(OF String) = GetHashSetMethod

Then in loop:

if (HashTest.Contains("TESTVALUE") THEN BLAH, BLAH, BLAH...

I have been using method 1. Should I even think about switching to method 2? Is there a 3rd option I haven't even thought of? Does it even matter because the data is cached to begin with?

IDE :: Cached Items In Toolbox?

Jun 10, 2010

I have a rather large project that several developers access via MS SourceSafe. The issue at hand is the ToolBox lists many, thirty plus, items that start Cached.(the name that follows Cached is the name of a class or Cyrstal Report in the project. There are also many items listed, they have the same "gear" icon, without the word Cached prefix on the class name.

My question is, how can I get these items out of the ToolBox so they never come back?

Reading Cached Images?

Jan 31, 2012

I've been working on my own web browser for a few years now using the webbrowser control in VB.Net.The following routine allows me to pull images on a web page that are stored in the cache:

Private Function GetCachedURLPath(ByVal lpszUrl
As String)
As Boolean

[code]....

This routine has worked well for me, but there are some pages where it is unable to pull the image from the cache. What discovered is that when a web page host images on a different server than the page hosting server, the images get stored in the cache with the address from the image server instead of the src address listed in the IMG tag. Given that I am using the URL from the src in the IMG tag, the routine fails to provide a return path.In most instances reloading the page puts the image into the cache with the same address as the scr record. It was fairly easy to write a routine that automatically reloaded the page when I could not find the image in cache, but one of the things I want to address in my latest revision is this issue.

I have a routine that allows me to run through all of the URL's for the files stored in the internet cache and using that I can figure out the correct URL for a picture, but this seems to me to be about as cumbersome as reloading the page and can be time consuming if the page has a lot of images.I can cut down on the time if I modify the routine to only run through the list on exceptions, but this just seems inefficient to me, especially since I have to make an assumption about what part of the image URL's are the same. What I'd like to do is to track the sources of the images as the web page is being drawn so that I have a listing of all the real source URL's for the images instead of having to rely on what is referenced in the src attribute.

SelectList Cached By AJAX?

Sep 20, 2011

I have a DropDownList in MVC which grabs a SelectList initialized and populated by a controller. The goal of the specific page that said list resides on is to reply "You have selected option X" immediately to the user without refreshing (using Ajax).The problem I'm running into is that for some odd reason, while the dropdown renders properly and even posts back correctly, any attempts to add new options or modify previous response messages are in vain.

My View:
<script type="text/javascript" src="../../Scripts/MicrosoftAjax.js"></script>
<script type="text/javascript" src="../../Scripts/MicrosoftMvcAjax.js"></script>

Should Changing The Parent Of A Listbox Change The Selected Index

Mar 22, 2012

You wouldn't think so, but it does when the listbox is bound to a datasource (as far as I can see).

I've reduced the behaviour to the code below. The "if" line toggles between loading a list via data binding and loading a list "manually" (both use the same data table). In each case I set the selected index afterwards, and then change the parent form. With manual loading, the selected index is retained, with binding it is lost. I cannot see how this makes any sense - I don't see why changing the host form should alter any property of the list. Is this a bug?

Public Class Form1
Sub main() Handles Me.Load
Dim ListControl1 As ListBox = New ListBox

Cached Objects Staying In Memory?

Mar 24, 2010

I have a asp.net web forms app that uses System.Web.Caching.Cache to cache xml data from a number of web services for 2 hours.

webCacheObj.Remove(dataCacheKey)
webCacheObj.Insert(dataCacheKey, dataToCache, Nothing, DateTime.Now.AddHours(2), Nothing)

Every 90 minutes a Microsoft Search Server hits a particular (spider) page which calls the code to put the objects into the cache.The issue i have is that over a period of time, the memory usage of the application grows exponentially. Lets say that in a week, the memory usage of the application pool grows to over 1gb

VS 2008 Change Form Opacity Without Changing Control Opactiy

Mar 16, 2011

I need to be able to change my form's opacity without changing the opacity of the components.

I really only need to do this on one form in my entire app, so this is getting a little frustrating

I've been researching for about half an hour now, trying to figure out if it's possible, but I'm coming up short.

I've seen some WPF examples and if it really comes to that, I'm more than willing to change the app from a WinForms app to a WPF app. I've made a WPF app before, so I'm familiar with it. But, I don't want to have to remake my entire project for this one form.

On that note, does anyone know if I can make a WPF form how I need it and just import it into a WinForm app? It doesn't seem possible, but it's better to ask than not. I'll look into this more.

Implement A Non-cached File Copy Using 2005?

May 7, 2009

I have a program I wrote that copies select files from one remote computer to another.
The set up I for testing is, one computer(a) at home running the program connected to my work's network via VPN and two computers(b,c) at work side by side on the same network. I am trying to copy the files on computer b to computer c, while the program is running on computer a.

The only thing wrong with this is, the files seem to be caching to a temp folder on computer a then going to computer c. When it should be going straight from computer b to computer c. Is there a way to keep the files from trying to cache on the computer running the app?

Keeping Tables Cached On Server In Project

Mar 7, 2010

I have an ASP.NET project which is a front-end to a database. In addition to the large tables, the DB contains a few small tables to help normalize the larger tables with common values. I have a VB.NET project which loads the smaller tables into memory, using "Shared" (i.e., "static" in C#) member variables, and uses them. I have a call to load the tables in Global.asax - Application_Start. This works for a while. That is, Application_Start runs when I first run my project, loads the cached values, and will correctly keep them in memory for a while.

What I'm seeing (when running my project via Visual Studio 2008 Debugger, hosted locally) is:

A) The Application_Start code will run more than once. Not in a row, but after the user has navigated to some other pages, I'll see (my breakpoint in) another call to initialize the cache, coming form Application_Start. Is it expected?

B) The "Shared" variable that was set to True when the cache was initialized is now False again (which should only happen when the class is first loaded). Similarly, all the data that was chached is no longer present. That is, it looks like VB is unloading all the Shared members. Is this expected?

UserPrincipal.Current.ChangePassword Does Not Update Cached Credentials

That is: when a remote user who is VPN'd in uses my application to change passwords, when they reboot and VPN is disconnected, they are forced to login to windows using there old password.

Is there a way I can force windows to update the cached credentials to the new password so upon reboot they are able to login using this new password?

Web Browser Control Working Offline - (Cached Web Pages) Only?

Is there a way to work the web browser control for viewing off-line (Cached web pages) only? Is it possible to view cached web pages from IE9 on a web browser control off-line? The reason i am asking this question is because IE9 automatically switches from off-line mode to on-line mode when it cannot find something in the cache by default. For forensic purposes this is not acceptable for these reasons: Active content (Viruses, java script, activex cookies etc)

Referring To A Previously Existing DataSet?

I'm working on a very basic VB.net frontend for an Access database and have stumbled upon a problem.

txtCourseReference.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(1)
txtCourseName.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(2)
End Sub

I get the error that Object Reference is not set to an instance of an Object. I think this is because I haven't defined the DataSet as "Course_assignmentsDataSet"- the one I want to use- but I'm not sure how to do this.

Use String As A Previously Created Object Instance?

Aug 9, 2009

Not sure exactly what I need to do to make this work, so my description may be lacking at first.Essentially I am writing a program launcher that recreates itself each time on load. It pulls the data regarding the tabs and buttons from an SQLite database and builds itself dynamically at run time. I get my problem when I pass the tab name through to the function that creates the buttons. I need the name to pull the right set of buttons from the database and I then tried to use the name to place the buttons on the right tab when I create them, but the debugger calls it a null reference because it doesn't point correctly to the tabpage that I'm trying to make it point to (at least that is what I'm guessing). Any ideas on how to make this work right?

Sql Server - Rolling Back Entity Framework Transaction, Cached Item Persist?

I'm using an Entity Framework context, and sometimes would like to create a transaction so that the client can do multiple changes and then commit/rollback them all together.However, if many changes were made, and SaveChanges() was called multiple times, after which a rollback is called, entities that were commited already, will remain the way they were commited, and would not roll back.Here's how my transaction-relative functions look like:

Public Sub BeginTransaction()
Dim context = HttpContext.Current.GetObjectContext()
If Not context.Connection.State = ConnectionState.Open Then
context.Connection.Open()
End If

Not only does the test fail, but it also leave the ObjectContext in an unstable mode, because it still has invalid changes in it.
