In general, you would use Environment.NewLine (say you are writing to a file and want to achieve the newline). In this specific instance, it looks like you are writing to a COM port so this isn't the case; what you have don here is correct.

No offense, but I think that's a bad idea in this case - he appears to be using a COM port, and writing something platform dependent to it does not seem like a good idea to me.

Ah - I hadn't noticed the COM port usage there. You're right that this doesn't make sense in this case.

\r\n works in C# (meaning that it produces a carriage return and a newline), what's the problem?

public void initest(string par==D, int val==1)
{

TxFrame = par + val;
TxFrame += "\r\n";

// the problem is the result of TxFrame is "D1\r\n"

m_ComPort.Write(TxFrame);

}

thanks

Ok, well then what do you want the result to be?
Or do you mean that you see "\r\n" in the debugger and thought that it meant backslash r backslash n?

genieabdo2-Jun-10 1:41

2-Jun-10 1:41

yes I see him in the debug and I want it to be a carriage return

Don't worry, it's probably already correct - that's just the way these things are displayed in the debugger

I've had to do a bit of work printing to serial printers and instead of sending the string value to the COM port, you might want to use something along the lines of System.Text.Encoding.UTF8.GetBytes(string) for TxFrame and then append the CR (0x0D) LF (0x0A) to the byte array. It seemed to work for me.

There are a few problems with your message:

1.
"carriage return" and "line feed" are the names of two popular ASCII characters.

2.
what you want to terminate a line of text and start a new one is called "NewLine" in .NET; it is a string and its content depends on your system (Windows, Linux, ...). The default value can be found in Environment.NewLine and will be used by some WriteLine methods, such as Console.WriteLine

3.
data sent to a peripheral using a COM port, or sent to another system in some other way (e,g, portable file), or shared with another system (e.g. a database), should NOT rely on a local convention or characteristic.

4.
the SerialPort also offers a WriteLine method, which relies on its own NewLine property which in turn is initialized to a "line feed". If you explicitly set to "\r\n", you will probably get what you want.

5.
the code in your other message, with initializers D and 1, will not compile as is.

6.
code snippets should preserve their formatting, that is what PRE tags are invented for. Use them!

7.
If you hope to be successful in programming, you'll have to become a lot more meticulous.

I only read formatted code with indentation, so please use PRE tags for code snippets.

I'm not participating in frackin' Q&A, so if you want my opinion, ask away in a real forum (or on my profile page).

Document merging in C#.NET

Why not something like:

m_ComPort.NewLine = "\r\n" ;
...
m_ComPort.WriteLine ( System.String.Format ( "{0}{1}" , par , val ) ) ;

Hi All,

I am sharing tips which is about Document merging in C#.NET.

Some times during application development we need to generate a MS Word document from a predefined format and some custom data. The predefined format is generally called as Template. This template used to carry some merge fields which can be replaced with the user data.
The user data can be taken from DB or XML data source etc.
The following procedure describe how to generate a MS Word document by merging a word template with external data using C# and MS Word reference libraries.

Step 1:Create a template word document
Hello {Recipient_name},
Wish you a very Happy New Year.
Thanks
- Here {Recipient_name} is called as a merge field and this can be replaced with the external content.
- The shortcut key to create the merge field in word document is : ctrl+F9

Hope you find this tipshttp://www.mindfiresolutions.com/Document-merging-in-CNET-734.php[^] useful and of assistance.

Thanks,
Bijayani

Should be a Tip or Trick

This isn't the right place to post this. This is a tip/trick, so it should be posted as one. By posting here, you have made it appear as though this is a question, and it will soon disappear from this page. I would suggest that you move it now.

Thankx in adv.

It would be helpful if you provide a more specific example of what you are trying to achieve. What do you mean on changing the appearance/look of controls?

Actually I want to change style of controls like- trianglr button, stylish appearance of any other control etc. Please suggest me any tool for VS 2005.

Without knowing which parts you want to change, I can only suggest that you look at the use of Themes if you just want to change the theme, or search for owner drawn (control of your choice) c# in google.
