VS 2008 : How To Clear WebBrowser's Cache/cookies

Jan 14, 2011

I am trying to have a DateTime variable which is in a MM/dd/yyyy HH:mm:ss format convert to dd/MM/yyyy HH:mm:ss. I am using VS2008 Pro, and when I create a var:

dim dt as datatime = datetime.now It automatticlly defaults to MM/dd/yyyyy.  No matter if I convert, parse, use globalisation or anything... convert to a string, which works with dd/MM/yyyy, but the minute i move it to a DateTime var type it goes back to MM/dd/yyyy I need to use this date/time to insert into a MS SQL Database and the colume is datatime type. But also is part of the app.I do not want this to be a string, I can do that, but I do need it to be a datatime in the correct format (dd/MM/yyyy HH:mm:ss)

Form With Multiple Tab Pages - Clear And Add Function

Jun 2, 2010

I guess, I am in some kind of trivial problem. Here is the scenario, I have a Form which has 3 main control two buttons "Button1" and "Button2" and 1 tab page control with two tab pages "Tab1" & "Tab2". Now Tab1 has one textbox controlled say "TextBox1" and one check box "chkBOX". What I am trying to do is, when I click Button1, only one tab page i.e Tab1 should be visible. Which I done using ".Clear" and ".Add" and is working fine. And now when I click on Button2, it should display the text in TextBox1, for this I have used:
msgbox(TextBox1.Tex)
Till now it is working fine. But when ever I use msgbox (chkBOX.checkstate), it displays 0, irrespective of control being checked or not.

ITextSharp - Calling AddImageToPage() With The The Optional Pages Parameter Will Add The Image To All Pages Though?

Dec 20, 2011

I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF

Dim Pages() As Integer
Pages = New Integer() {1, 3}
PdfManipulation2.AddImageToPage(..., Pages)

Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.

Form On A .NET Webserver Using Aspx Pages With The Vb Code-behind Pages?

I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:

Make Html Pages Work Like Aspx Pages?

Jun 19, 2009

I have heard of setting server specs to have HTML pages parsed as PHP pages by changing the .htaccess or httpd.conf files. Is there a similar solution to have HTML pages parsed as ASPX pages?

A website I am working on does not want their PageRank to lower since their HTML pages are already indexed and used on other websites but wants to use some dynamic features of aspx pages (like include the navigation file so that changes to the nav will only have to be done in that one file).

ASP.NET CACHE Or SQL CACHE

Apr 20, 2011

I have an application that allows users to bid on items that are put up in an online silent auction type of deal. Currently, When a user clicks submitBidButton, the application stores the bid in the database, and then updates the price. Sounds simple? It was.. until it got popular. If there is a bidding war on the page, my application, and SQL database start crying.. literally. 

About consuming the data with jquery/JSON.. and WebMethod. It works like a champ. BUT. How can I take advantage of Caching to increase the performance of my application? SQL Caching? Asp.NET Caching?

Each member places a bid, and I want to add a ajax timer that calls back to the server every .5 seconds to see if a user has placed another bid. The app was built in vb.net.

Why Did Clear() Clear Both DataTables

Feb 28, 2011

In my winform program (in vb.net) I wrote:

Dim dt As New DataTable
'Get data from DB into dt
'...

[Code].....

But when I run the program, Clear() cleared both dt and dttemp! Why? Aren't dt and dttemp supposed to be two distinct instances of DataTable?

(I finally found a solution - dttemp = dt.Copy() instead of dttemp = dt. But I still can't see why Copy() was necessary in this case.

Assembly Cache

Apr 6, 2010

I have 2 dll files from a third party, and they have the same name (v7 and v8). My program needs to be able to use both of these dll's (meaning wether the enduser has a lisence for v7 or v8 of the thirdparty dll, they can still use the program). But I am stopped from referencing both of them as they have the same name. How do I resolve this? Searched the web and found info about sn.exe and strong names, but can't find a good explanation of how this works. Anyone?

Asp.net - Object References And Cache

May 11, 2011

I have a function GetAllProducts() which fetches all products from a database and stores it in the cache for future requests. This works fine, but if I then call the function e.g. ProductSearchResults = GetAllProducts(), and then modify ProductSearchResults variable, this also modifies the cache, which is very important this never happens, as the cache affects the whole website.

I understand this is because both ProductSearchResults and the cache now have the same reference, but how do I solve the problem? Is there something that I can put in GetAllProducts() to ensure the cache always uses its own value?

Global Assembly Cache (or Not?)

Dec 1, 2010

If you build and deploy UserControls, Components etc do you give them strong names and put them in the GAC or do you simply place them in the same folder as the executable?I've made a component that will be given to other developers and they will, in turn, deploy it with their own applications. If I give my component a strong name and install it into the developer's GAC then I assume that the developer using my component will also need to place it in 'his' customer's CAG when he deploys his own application containing my component.

Stand Alone Exe + ClickOnce Cache?

Nov 17, 2009

Two separate but related questions about deploying a Visual Basic 2008 .net application:1.  Click One installs in a cache under local data.  The EXE launches from the cache even if not on-line.  I don't want my users to have a runnable EXE left over in their cache after exiting the program.  Is there a way to delete or disable the cache contents on close of app or equivalent? 

2.  My EXE uses an interop DLL.  I want my EXE to be a single stand-alone file so that I don't have to copy both the EXE and the DLL to the user.  Is there a compile setting to incorporate everything, includng the DLL, into the EXE.First question relates to Click Once Web deployment.  Second question refers ONLY to ordinary COMPILE, not click-once.

VS 2008 - Deleting Cache While Using Webbrowser

Oct 21, 2009

I'm writing a program that uses a webbrowser to update a page and gather its data. But it's reloading the page from the cache. I located the cache and quickly found that it cannot be deleted like normal files.

Now i really only need to delete one file, specifically a javascript file, because that's the only thing i need updated. But deleting the cache is proving to be a bigger problem than i thought, let alone deleting a single item from the cache.

VS 2008 Cache Contents Of Up To 100,000 Files?

Jun 19, 2009

I'm designing a solution that involves a windows service running on a server that will have multiple clients requesting data from it. This windows service needs to read a few short details from some text files on the server, however there could be anywhere from 1000 to 100,000 of these text files. I've already written my code that goes through each of these files and extracts the relevant information from them and populates the properties of an instance of a custom class, then adds the class to a list. The problem is that if there is a large number of these files then looping through them all takes a long time and there are constantly new files being created and deleted in this folder as well, so I have designed the following system:

1. When the service starts it goes through every single file and gets the data I need from each one and writes it to an XML file (just one XML file that holds all of the info for all of the files, not an XML file for each one). It also stores the file name with each entry and then once it has done this loop through all the files the first time it goes through the file paths in the XML file and checks to see if this list of files is the same as what is actually now in the directory (as new files may easily have been created during the initial scan process). I figure this shouldnt take anywhere near as long as the initial scan because it is just checking to see if the same files exist, not reading data from all of them (although it may read data from the 50 or so that might have been created while the initial scan was running). 2. Once it has a list of files in the XML file that is the same as the real list, it starts a FileSystemWatcher to watch for any new files being created/deleted. 3. If the FileSystemWatcher finds a new file then it reads the info from this file and adds it to the XML file. So now when a client requests data from the service, the service just reads through the XML file and basically returns the entire contents to them. This should be much faster than the service reading through every single file every time a client requests data.

All I want to know really is - does this sound like a decent design? One problem I am curious about is what will happen if a client requests data at the same time as a new file being created, because the service will be trying to read from, and write to, the same XML file at the same time... I guess one way around this would be for it to check for a file lock before it tries to write the data and just keeps trying until the file isnt in use (say every 5 seconds or something)

I am using WCF for the communication between the client and server and WPF for the client side app.

Asp.net - Invalidate A Single Data Item In The .net Cache In VB

Jun 3, 2010

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

I use these functions to hold user data that I don't want to access the DB for all the time. However, when the data is updated, I want the cached item to be removed so it get created again.

C# - Why Does Response.Redirect Sometimes Pull Page From Cache

Jan 18, 2010

I've noticed that when I Response.Redirect to an .aspx page, it sometimes displays a cached page instead of actually executing the page and pulling fresh data from the database. I'm not using output caching or anything special in .Net here -- this is a CRM, and the caching is either happening on the client or, perhaps more likely, automatically in IIS. There is never a querystring involved, by the way. I'm passing a key via session. I know that if I used the querystring it would probably partially bypass the cache problem, but it's not an option in this case.

I did a little digging, and some people get around this by using Server.Transfer (which actually behaves differently than Response.Redirect and some of the details are not always desirable), and some other people said to set Response.Cache.SetCacheability(HttpCacheability.NoCache) on the page where I want to avoid caching. I thought .aspx pages were always flagged to avoid caching. Right?
