View 11 RepliesHTML-encode A String And Use Human-readable Encoded Tags?
Apr 14, 2010Greetings, 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.
C# - Can A String Encoded With Base64 Not Contain "+"
Dec 3, 2009I need to Base64 encode a string, but the encoded string cannot contain "+". Wikipedia mentions a modified Base64 for URL, but I can't find a .NET class which uses this.For my application, I can't even URL encode "+" into "%2B". This is because I pass the encoded string to a service which I have no control over, and that service mangles any strings which contain "%2B". For this reason, I want my encoded string to only contain A-Z, a-z, 0-9, -, and _.

View 4 RepliesC# - Writing String To A File Is Generating Unexpected Content?
Apr 11, 2012I've two Strings which I'm loading from a SQL Server 2008 database (nvarchar-field)After loading them from the database Visual Studio 2010 displays them as follows in the watch window:
str1 = "Test"
str2 = "Test"
But the comparison with str1 = str2 returns False If I write those strings to a file with UTF8 Encoding the result is as expected:
Test
Test
If I write those strings to a file with ANSI (Default) Encoding the result is NOT as expected:
?Test
Test
Converting the strings to bytes:
System.Text.Encoding.Default.GetBytes(str1) 'Returns ByteArray {63, 84, 101, 115, 116}
System.Text.Encoding.Default.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str1) 'Returns ByteArray {239, 187, 191, 84, 101, 115, 116}
System.Text.Encoding.UTF8.GetBytes(str2) 'Returns ByteArray {84, 101, 115, 116}
Where is the Byte 63 in case of ANSI Encoding OR Bytes 239, 187, 191 in case of UTF8 Encoding for str1 coming from?Well, Bytes 239, 187, 191 are the BOM for UTF8. The question here would more likely be: Why do I get the BOM for str1 but not for str2?(Well, the values are values passed to a webservice which inserts them into the database, the initial values are passed to this webservice by a client I've no control over)

C# - Generating Code - Get A Proper String Representation Of Nullable Type?
Mar 17, 2010So I'm building an application that is going to do a ton of code generation with both C# and VB output (depending on project settings). I've got a CodeTemplateEngine, with two derived classes VBTemplateEngine and CSharpTemplateEngine. This question regards creating the property signatures based on columns in a database table. Using the IDataReader's GetSchemaTable method I gather the CLR type of the column, such as "System.Int32", and whether it IsNullable. However, I'd like to keep the code simple, and instead of having a property that looks like:

Jan 11, 2011I have a data table being returned that populates a repeater. One of the fields has the & character in the data and displays perfectly within the asp:literal on the screen. The source shows the & character un-encoded.My question is this: Does it NEED to be encoded? A co-worker is insisting that it must be encoded in order to be "HTML compliant". But it works perfectly for display purposes. Is this REALLY required for any type of compliance that I should even be worrying about?

How To Convert Standard To Encoded Hex
Sep 3, 2011I have an example of standard text (in Hex form) in a specific encoding (selected by the user). And I have a weirdly encoded text which is in the same encoding but a little different. How do I convert the Standard to the encoded Hex?
Cyrillic (ISO-8859-5) Example:
## 12 91 BB BE BA B8 C0 2E 20 CD BA C0 B0 BD B0 20 B8 20 BA BB B0 B2 2E <- ALTERNATIVE
B1 DB DE DA D8 E0 2E 20 ED DA E0 D0 DD D0 20 D8 20 DA DB D0 D2 2E <- STANDARD
Diff. from Standard (in Decimal): -32
Hebrew Visual (ISO-8859-8) Example:
## 1C 0B E0 E2 D9 DC EA 20 DE E1 DA 20 D5 DE E7 E9 D9 DD <- ALTERNATIVE
F0 F2 E9 EC FA 20 EE F1 EA 20 E5 EE F7 F9 E9 ED <- STANDARD

.net - Read 2D Barcode Encoded With Base256?
May 25, 2012I have to read a 2D barcode that's encoded with base256. When I scan the barcode, it sends different characters as it comes from the keyboard and it changes the focus, turns visual studio in full screen, give the command to send to printer from notepad++.
I guess it reads ALT + TAB, CTRL + P, ALT + SHIFT, etc. and i can't capture all the bytes from the barcode.
I tried to capture the event on textbox KeyPress method with e.handled = True and e.keyChar added to the bytes()
On form.load I set:
Me.KeyPreview = True
And tried also on form.KeyDown with no luck.
C# - Which Datatype For Base64 Encoded Image
Jul 29, 2010Question: In order to store logos in a database and display them dynamically in ms-reporting service, I need to base64 encode the image. It doesn't work with binary saved images, due to MS limitations...
Now my question: Which datatype do I use? Varchar, nvarchar or text? I guess varchar would be good enough, since base64 encoded, but images might be larger than 4000 characters...

Convert Base64-encoded Text To Hexadecimal?

"48YwojCi4yaiow==".
I need to convert this string to the corresponding Hexadecimal text(The sample stands for "Thisistest" in hex text) The below link is an online converter from base64 to hexadecimal text. If you give the same base64 encoded data in the link , click on convert, the one that is seen below "Hexadecimal text" is what I need.

Use With A Textbox In VB Swiping A Card With Magnetic Encoded Data?
Feb 15, 2012I have created a program in Visual Basic using Microsoft Visual Studio 2010 Professional. There is a textbox that I use in the program that when the focus is placed on it will take the data encoded on a magnetic striped card such as a driver's license or any card that has this kind of data encoded magnetically. Very simple to get the data as the program takes all of it upon the swipe without having to do really anything, however, the problem is that I don't know which declaration to use when the swipe has stopped - or the last character has been entered. Currently I am using TextBox1_textChanged as my declaration, but that is called every time each character is put into the text box. When you are swiping, this is an ongoing process until the last character is put in. So if I have a magentic card with 10 characters in it, this method will be called 10 times. Is there a declaration that I can use that only fires off whent he swipe has loaded all of the characters or some kind of loop that I can incorporate?

View 3 RepliesReading ID3v2 Text Identifier Tags When They Are Encoded In Unicode
Jun 13, 2007I have a problem reading ID3v2 text identifier tags when they are encoded in unicode. If i update the tags using winamp the tags are encoded in UTF-16 with BOM. When i try to read the tag i step through each byte and use chr(byte) to get the character that that byte represents. But when the bytes are unicode i get some characters (shown below) as the first two characters:
The remaining characters are correct, it's just these 2 first ones.
What are these for? and how can i get rid of them or read the bytes as unicode characters? i've tried reading the ID3 website and many other sites too but i don't know what to do. i can check the text-encoding byte in that tag frame to determine whether or not the tag is encoded in unicode or ISO-8859-1 but i don't know what to do next.

C# - Generating Excel Through .Net Doing Odd Things?
Feb 4, 2010I have a rather odd thing happening with an Excel WorkSheet that I am creating through .Net.I load up an existing workbook
Dim _xlApp As New Excel.Application
Dim _xlWorkbook As Excel.WokBook = _xlApp.Workbooks.Open(_templateFileName)
set it to be visible before populating it (for debugging purposes)
_xlApp.Visible = True
I then go on to populate the existing template.
Private Sub GenerateOceanFreightGrid()
Dim columnCount As Integer = 4 ' _standardColumnCount
Dim columnInsertPosition As Integer = 5
[code]....
When i set a breakpoint on the "Private Sub Gen.." line, and step through the code line by line, it inserts a new column for each variable declared, so in this case it will insert two columns before it even hits the "If MyBooleanValue()..." line (I can watch it actually happen due to the Excel app being visible). However, if i dont set a breakpoint and just let the code run straight through this doesnt happen.There is no multi threading happening or anything else that i suspect would have any impact on the code.
