C# - How To Put Escape Before Special Characters
Aug 15, 2010buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case I want it to be written in c# or VB.NET
Correct Way To Escape Characters
Jan 30, 2009I have a couple of strings (in Ms-Word) which I copy and paste into variables in visual studo. Ms-Word uses high ansi characters for double quotes ("x"). I need the same in my app too. There seems to be no easy way to do this.
1. Visual Studio converts them to simple double quotes ("x") if I let it format the line automatically (auto-indent/auto-format).
2. If I turn autoformatting off and put those characters, I can see the correct characters in the code in Visual Studio editor. But when program is run the behave same as the simple double quotes. They are treated as simple double quotes and converts to simple double quotes in the output.
The only way I could find out is to use Chr() etc. functions to concatenate the character codes at appropriate places. But that's tedious on large strings. I want something to escape these characters appropriately (just like we can put two double quotes to escape the simple double quote character). [code]
1. What is the correct way to escape these characters? I don't need string concatenation; I need it in one string (like x="abc").
2. Are there any other characters also which visual studio messes up?

Regex - .NET Regular Expressions, Matching Escape Characters?
Dec 3, 2010I want to use Regex.Replace to replace a Match with a context sensitive value. I use the MatchEvaluator for this. But to make things simpler lets say I'm matching %v I want %v to be escapable, so if I use \%v it will not match. Anything else should match.
The pattern I came up with is this: (?:[^\]|^)%v It basically matches %v if it occurs at the beginning of the string, or if it follows any character except . It doesn't capture the first part of the expression.I know this isn't the "right" way to do it. But it worked just fine until I noticed that when I use this pattern in a replace, it includes the character before %v in the replacement(duh, right?)So, if I have ThisIsAValue:%v and I do Regex.Replace, replacing with the string Value, my result will be ThisIsAValueValue instead of ThisIsAValue:ValueI've tried googling this but the fact that "escape character" is so heavy in RegEx, all the results are geared towards the USAGE of escape characters instead of picking them out with a pattern.

View 1 RepliesSql - Unable To Escape Apostrophe/special Characters In Parametrized Query
Nov 30, 2011The data was being read from a Gridview which had the html encoding. The solution was the following...
Dim Sht_Text As String = HttpUtility.HtmlDecode(row.Cells.Item(0).Text)
I am trying to prevent from having to escape apostrophes and other special characters in my string variables by using a parameterized query with an OleDbConnection. I have all of the parameters in the same order, the insert is working, it just does not maintain the characters. I keep getting those pesky html codes. I am trying to insert into an Access db from a web pages. As I mentioned, its working, just not the special characters.
Here's the code:
Dim pConn As New OleDb.OleDbConnection pConn = New OleDbConnection(cb.ConnectionString)
Dim SqlString As String = "INSERT INTO Strings (Mlt_String_ID, Lng_ID, Strg_Name, Sht_Text, Lng_Text, Alt_Text) Values (?, ?, ?, ?, ?, ?)"
[code]....
jp and en records already existed, the insert of fr record pushes the html codes for the small circle which represents the degree symbol. Happens for all other special characters as well.
Catching And Removing Escape Characters In A Serial Comm Port Program?
May 18, 2010I have recently developed a serial port communication program to access my hardware firewall and its connected to the device via a converter usb to rs232head plugged to a rs232 to an ethernet cable. this ethernet cable then plugs into the device console port.
my program functions similar to that of TeraTerm. an opensource hyperterminal program written in C++ but i decided to do one for vb.net
Alright to cut the story short, i have successfully coded out the program to accept incomming data from the device but however, i'm also receiving ansi escape sequence along with it and i have no idea how i could implement codes to remove these. i have spend 3 weeks trying to look for vt100 emulation codes written in vb.net but i found none so far. most are written in c++. here's an image to illustrate the problem which im facing.
The image below is a screenshot taken when the i ran both the programs together. The bottom is tera term 3.1 and the top is my vb project which i made using msdn's example and improved on the codes. basically tera term was able to interpret those escape sequence and display accordingly to that of the vt100 terminal display. I have spent time reading on regular expressions using the inbuilt function regex in visual basic and tried parsing some strings but its not working. i guess its far more complex than i thought.

Writing XML Attributes With XMLWriter?
Jan 18, 2010I'm trying to generate the following header for an XML document using VB.NET and the XMLwriter but have been unable to generate the "xmlns:xsi" and "xsi:noNamespaceSchemaLocation" attributes. It seems I'm missing something, I was hoping someone can help with the XMLwriting calls and maybe even explain a little bit of what those attributes are doing.
Required Output:
<?xml version="1.0" encoding="utf-8" ?>

The above code isn't producing what I need. Other code I've tried, like passing "xmlns:xsi" as the name of the attribute produces error.
Xml - XmlWriter Not Creating New Element?
Oct 23, 2009I'm writing out an XML file using VB.net. When I try to create another element to be written past the first, it errors out saying:
"Token StartElement in state EndRootElement would result in an invalid XML document. Make sure that the ConformanceLevel setting is set to ConformanceLevel.Fragment or ConformanceLevel.Auto if you want to write an XML fragment."
I'm not sure why it is doing this considering that the previous element has been closed. I tried to look for a writer.WriteEndRootElement, but I didn't see any in there. Any suggestions to get it to work?

XMLWriter: How To Change What's In The Header
Jun 22, 2009I have a requirement to make an XML file - and the partner is rather sticky about the header. Apparently, the header must be exactly this:[code...]
The hacker in me wants to stop using XMLWriter to make the file so that I have more control over the header; "no problem, I'll just write a loop that makes its own XML tags as a StreamWriter or something, forget this XMLWriter object..." but I must admit that XMLWriter has been rather elegant to use so far; surely there must be something where I can change the XMLWriterSettings object to say "stop putting your custom properties in to the XML header please", right?
[code...]
Works perfectly; but I can't find a way to control the header. I can find a way to remove it entirely of course but that's not what we want to do.

Can't Escape Empty Textbox?
Jan 6, 2011I'm trying to track down the cause of an annoying interface bug in an app that was ecently upgraded from VS2003 to VS2008 (the bug did not exist pre-migration).What happens is this :1) User clicks in textbox containing a date.2) User clears date3) User tries to move to another field, but can't. No error messages appear - it's as if the validation failed.Further info :1) The textbox's Text property is bound to a dataview which uses a datatable as its source. The bound field is a nullable datetime field with no constraints or default.2) The Validating event fires and the CancelEventArgs property is not set to Cancel. The Validated, LostFocus and Leave events all fire as well, going LostFocus > Leave > Validating3) I can't see any code changes relating to the control or the datasource with a couple of exceptions. The first is that this :
Me.txtRangeEnd.DataBindings.Add(New System.Windows.Forms.Binding("Text", Me.dvClientNos, "RangeEnd"))
