.net - Escape The # Character In A String Literal?
Dec 10, 2009If 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.
Print Escape Sequences In Program?
Jan 9, 2012I see that print methods have changed in for vb.net 2010. I have looked up and down the internet and have found many examples for earlier versions of vb, but these can not be used in 2010.
I can not use graphics.drawstring / printdocument method because I need to send escape sequences.
How To Escape Single Quote In String.Format
Jun 24, 2010While 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 3 RepliesCatching 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.
SerialPort Escape String - Retrieving Data From A Device Connected To A Virtual Com-port
Aug 13, 2010I am writing a small app that is retrieving data from a device connected to a virtual com-port. I connect without problems to the device using the settings 9600-8-N-1.
I need to send the command <esc>MS , the device then sends back the data to a computer. I have tried this using Hyperterminal with success. I also did this with Excel and VBA. I used the MSComm32 Active X control:
MSComm1.Output = Chr$(27) + "M" + "S" + Chr$(13)
Msgbox(MSComm1.Input)
This made the data from the device pop up in a messagebox. I am writing a winforms app in vb.net, using VS2005. I have a form, on which I have a Placed a SerialPort control, named sp. My sample code is as follows:
Private Sub Form1_Load(ByVal
sender As System.Object,
ByVal e
[CODE]...
This returns the error message "Error: expecting a command". I have done som tests in HyperTerminal, and have concluded with:
-If I dont send <esc>, I get error "Expecting a command"
-If I send wrong command (ie MD instead of MS) i get error "Bad command"
Based on this, I suspect that I don't pass the escape character correctly to my device. So I wonder how to do this?
Replace Slashes In .Net?
Feb 28, 2010I have a local file path containing "" and I need to change all occurrences to "/" for a remote file path.
I have tried
myString.replace("","/")
and
myString.replace(Convert.ToChar(92), Convert.ToChar(47))
Both seem to leave the "" in tact..
Answer:
NewString = myString.replace("","/")
The problem was that I was not assigning it to a variable. Escaping the slash actually made it fail, in vb.net at least.

View 5 RepliesEscape Key Words In C#?
Apr 6, 2010I want to do the equivalent of the following VB in c#

This would be the same as this in c#

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
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"))

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?

But the SQL statement below fails saying
