Detect A String's Code Page And Encode It?
Nov 4, 2010
I am trying to detect if a string's encoding if different than cp1251
- usually its koi8-r and if so convert it to cp1251
As I understood it can be done using encoder and unencode?
I tried searching on the subject, and find almost nothing. I am kinda lost.

I've made a class to encode a string
Public Class UTF8
Public Shared Function encode(ByVal str As String)
Dim utf8Encoding As New System.Text.UTF8Encoding
Dim encodedString() As Byte
encodedString = utf8Encoding.GetBytes(str)
[Code]...
Return encodedString.ToString() always returns "System.Byte[]". How could I get the real UTF-8 String?

all ` should be replaced with `` right? Well, is there a function built in by vb.net that does that sort of thing already?
That way I do not have to encode it.By the way, I do not access sql database directly. Basically I am creating a text file and that text file contains raw sql statements. Most of the answers deal with accessing sql data directly.

I have the following code:
Dim lStatementText As String
Dim lStatementString As New System.Text.StringBuilder
lStatementString.Append(RndRes.Forms.txt_request)
lStatementString.Append(" ")
lStatementString.Append("<b><a>")
[Code]...
Where Request.ID, Request.Description and also RndRes.Forms.txt_* are all strings. I want to display the string I build up here in a Infragistics FormattedLinkLabel. The problem is that if any of the strigs from the Request class contains a HTML character, the label is not displayed properly and the HTML encoding is broken.I need to find a function that masks the HTML codes.

Greetings, I'm looking for a way to encode a string into HTML that uses human-readable tags such as ê (=ê). At the moment, I am using the HttpUtility.HtmlEncode() function, but it appears to return numbered tags instead of human-readable ones. For example:
Dim str as string = HttpUtility;HtmlEncode("vente - en-tête")
'Expected: vente - en-tête
'Actually received: vente - en-tête
Is there a setting or function in ASP.Net to encode a string into HTML resembling the first comment?
EDIT: I am looking for this kind of functionality because the text is saved HTML-encoded in the database. The text comes from a bunch of MS Word documents that have been converted to HTML.

Right now I am using this code on client side.
[Code]...
The values for the hidden fields are already set. I want these value to open a window, in which the fields will be already filled using the values passed by this page. This code is working fine on Internet Explorer, but not on other browsers. Moreover, when I don't pass any value and just open the required window, it works on all browsers.

I have wasted lot of time in searching and finding the simplest way to detect a page refresh and when the user press F5 button on his browser.I have seen most of the samples provided on net but none of them could satisfy my needs.I will explain in a simple step way to understand my issue:
I am trying to use sessions and loading some images and storing them to folder.Next I have a button to process some operations on images.(Here I have a postback where I am trying to detect postback and savng them to the same folder.)Now here comes my issue now whenever user tried to refresh his page manually or by clicking F5 buton on his browser I need to load all the images again from the folder.Here is my code:
If Page.IsPostBack Then
//Here I am checking if the session is there or not.If it is already there I am adding images.
Else
//
Here I am creating a new session and adding images.

I am creating a notes software. This is just a simple application that will show the data from the database which are Notes_Title, Due_Date, Priority. I display the data with datagridview. I also added a checkbox for each row to the datagridview to mark as check if the Notes_title is already done. In displaying the data, I need to display only a 5 data in a row.So, I create a another CLASS that will only show 5 rows per page. But the PROBLEM is, if I mark the checkbox as check in the first page then if I turn it to the next page the checkbox in the first page that mark as check will be uncheck if I turn it back to the first page. The mark check in the checkbox will mark as uncheck if I turn the page. How can I make it mark as check even if I turn the pages? And How can I save the data row as done if I check

This code was intended to split a long text file into pages based on the calculations of lines_per_page.The code only prints one page of a three page document.But a very strange thing happens if I click print a second time the message box which shows "Document 1 Page X of XX goes crazy up to 100 pages until I click cancel.The code compiles fine, just doesn't function as intended.

I have an ASP.NET 3.5 page with some AJAX, some Validators and some business-rule validation done in the code-behind page (VB.NET).
The Validators set focus to the 'offending' control when an error is detected.
When a business rule is violated, I used the following code to generate some javascript "on the fly" and execute it to simulate the Winforms "MessageBox.Show" functionality:
Sub DisplayMessages()
Dim lblError As New Label
lblError.Text = "<script language='javascript'>" & Environment.NewLine & "window.alert('"
[Code]....
At the end of the "btnSave.Click" code, if everything went ok, calling that subroutine.
What I get is the page scrolling to the top and then back to where it was when the Save button was clicked.
For various reasons, 'MaintainScrollPositionOnPostback="True"' is in the Page directives at the top of the .aspx code. What I'd really like is to make that FALSE for just a moment so that the page resets at the top - again, only if everything is ok and only for this button (there are other buttons on the page that require the page to keep it's scroll position).

I have a nested master page that has its own master page. The parent master page has a property defined in its code behind.
Public ReadOnly Property SelectedPage() As String
Get
Return _selectedPage

How can I reference the parent master page's property from within either the child master page's code behind Page_Load or aspx template page?

I'm trying to track down a problem on our test environment. Previously it was set to use InProc Session State Type, but I've added in the SQLServer type for one specific Web App. I did this because we use the SQLServer type in our production environment and I want our test env to match as closely as possible.
However, after changing it to SQLServer I do not get any errors when trying to store unserializable data in session like I would expect. It works just fine, even though I would think it shouldn't. I'm a relative newbie when it comes to configuring this, but from the various tutorials I googled, I thought I covered all the bases.I was wondering if there's any code snippets to verify which session state type an application is actively using.

I need code to fit for an 'if then' statement based on an operating system. So let's say I am running windows XP, the program detects it, and with a simple if then' statement it opens form2, if i was running vista, it would open form1. So basically i need something like: If (WindowXP current OS) then form2.open, If (windowsvista currrent OS) then form1.openOf course, the above statement won't work because I need code to support the detection of the O.S.Note: I just need code for just these two O.S'es, also I don't care if its Windows XP SP1 2, or 3, just as long as it's an XP.

I'm downloading a page and stripping out the HTML. I actually stripped out everything successfully, but there is something weird with the "<br />" tag..
When I try to replace <br />, I can't detect it..
Unlike other HTML tags such as <br> and such, <br /> does not show up as a text in my TextBox.. it shows up as a BOX and messes up the whole formatting.Does anybody know how I can go about removing the boxes from my textbox?
