I want to do the equivalent of the following VB in c#
Function([class]) "hello"
This would be the same as this in c#
class=>"hello"
The problem is that the word class is a key word in the language. But I want to use it as a variable name. In the VB example you can use the [] brackets to 'escape' that key word and allow it to be used as a variable name.
I've got 2 RTB one is for input of text and one is output.The output one needs to read the words from the input and display it alphabetically and with their line numbers.I have partly done it and it currently reads it but here is my problem When the words are outputted let say for example there are 2 words the same on the same line e.g the word 'you' appears twice on line one,at the moment its coming up like this

other than GML (Yoyogames.com Game Maker Language), I am new to the coding world. The only "major" project I have completed using VB is a computer calculator that exactly mimics the capabilities of Windows 7's calculator. Yesterday, I began a Chatbot program for my girlfriend. Lol. I have used the instr() function to answer most of the questions or answers which are typed into the textbox1. I find this extremely troublesome because when using the instr() function you cannot say instr(textbox1.

I want to write a code
Dim comm_update As New OleDbCommand("update item set status = "On Loan" where itemid=@itemid")
I know I cannot write "On Loan" as above, but I don't know what's the right way. status is an attribute in my access table.The SQL should update the status to string "On Loan"
buildLetter.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
I need to convert this string to the proper form in my vb,net code

s.Append('"');
} else if (c == '\') {

I'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"))

I 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?
For displaying the character & in a button as text, i am using &&

View 4 RepliesIf I needed to escape a double quote character within a string literal I'd use two consecutive double quotes as follows:
Dim name = "Chuck ""Iceman"" Liddell"
However, it doesn't seem like consecutive # works the same way. The compiler is expecting a compiler directive to follow the # character, even when its enclosed in double quotes. How can tell the compiler that I want a # character in my string?
EDIT: as a few of the answers below point out, # is not a reserved character. I closed my solution in Visual Studio and re-opened it and no longer got the compiler squiggles warning me.

View 6 RepliesI'm trying to execute an sql statement in vb.net to an Access database, I am escaping the reserverd word using square brackets []. This has worked in all my SELECT statements within the program.
The reserved word is level
But the SQL statement below fails saying
Syntax error in INSERT INTO statement.
If I directly copy the statement and execute this in Access it works fine
datalayer.getDataTable(String.Format("INSERT INTO users (username, password, [level]) VALUES ({0}, {1}, {2})", username, password, level))
The above statement works if I remove [level] and replace this with another column name.

While searching on how to escape a single quote in String.Format, I found the answer at SO: Escaping single quote in String.Format(). It seems to be different for VB though. I tested it, and indeed C# needs
string s = DateTime.Now.ToString("MMM d \'yy 'at' H:mmm");
while VB needs
Dim s As String = Now.ToString("MMM d 'yy 'at' H:mmm")
Why does C# need a double backslash, and VB a single backslash? This might be a bit of a silly question to C# users, but while I can read C#, I'm not used to writing it.

View 4 RepliesI tried writing the following TestCase for an NUnit test written in VB.net:
<TestCase("FirstNode", "<node id="FirstNode">")>
Public Sub GetNode_GivenSomeNodeId_ReturnCorrectNode(ByVal nodeId as String,
ByVal expectedXml as String)
[Code]....
The xml-node passed as the second parameter to the testcase is not valid however, as this clearly is not the correct way to escape double quotes. I'm sure I can find a workaround in order to check that the method under test returns the expected XML-node, but I'm curious:
Is there some clever way to pass a string such as this, containing double quotes, as a parameter to an NUnit test?
What tools/methods are available to build pcl stream from PDFs.We have a bunch of generated PDF files that get tied up into one big pdf.I need to generate a print job to print this with the ability to insert pcl escape sequences (to control paper feed and output bin stacking) per page. As of now we use the VB.Net printing classes, convert the PDF into a rasterized image using a third party tool to print. This does not allow us to insert PCL sequences into the print job.
So, basically, we need to process a bunch of PDFs, append them to the pcl and insert PCL commands as we go along. Is there a way to achieve this. Our application is written in VB.Net.
I 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.
Here is my code snippet:
Public Function convert(ByVal robert As String)
Try
robert = Replace(robert, "U", "A")
