Thanks for your idea.
But i resolved it in the following mode:
double d = 9.999 - 0.005;
Console.WriteLine(d.ToString("0.00"));
and this gives me the result 9.99 (what i need).
And when you need a double value with 1 decimal(no rounded) just substract 0.05, and so on for all numbers.
Have a nice day!

Has anyone worked on how to read the barcode output from the barcode reader.
The barcode reader produces its output in the notepad.
But i want to get the output and then format it.
Kindly suggest on this issue.
|
|
|
|
|
well, at least for the barcode readers i know:
if you scan a specific barcode, the reader just emulates some
keyboard input and the textual representation of the barcode
you scanned gets inserted into the textbox that has focus.
you could even create a console application, do some Console.Read()
and can then do whatever you want with the string representing
the barcode.
so it's up to your imagination!

Dear Sid,
I am using this piece of code in thread.It tells me when client is connected and send data to me.
Socket listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
IPEndPoint endpoint = new IPEndPoint(IPAddress.Any, 8001);
listener.Bind(endpoint);
listener.Blocking = true;
listener.Listen(0);
Socket objSock = listener.Accept();
objSock.Receive(ReceiveData);
objSock.Shutdown(SocketShutdown.Both);
listener.Close();

Hi,
I have learned how to load language specific string from sattelite assemblies by changing the CultureInfo of the Resource's typed class accessor. Now, I am wondering how can I set the culture specific language for the Microsoft's built in UI. For example, I want to change the language of the TextBox's context menu (Cut, Copy, Paste) as there is no "culture" property available for the class Control. Would you please give me any idea.
Thanks
|
|
|
|

use System.Globalization,
There, you will get Cultureinfo and RegionInfo Class.
just go through this.
you can also build custome culture using CultureAndRegionBuilder Class!!!

I'm trying to design my user interface where the user can change the background/foreground colors according to their preference. The XML file format appears to be the best and I would like any advice on making it as effecient as possible. The file's contents could change multiple times (re-written). Is overwriting XML file a good idea. Is there a better file format?
Thanks guys!
may your code be error free.
(okay, maybe two lines.)

programmingAddict wrote: Is overwriting XML file a good idea. Is there a better file format?
For reading and writing XML files, you can use XMLDocument class which provides a DOM model for the supplied XML file. This class provides methods for creating new node/attributes etc. For reading XML files efficiently, use XPath.

Thanks for the info. It will get me jump started. The more I look into XML, the more convinced I am that it's my best option. Some of the replies to this thread thought I was intending on the user writing the strings by hand 
My opinion of user interaction with text is to limit the use of a textbox AS MUCH as possible! When the user gets a hold of a textbox that will be inputting critical data, bad things will start happening if serious validation is not done.
Best wishes to your code!

Depends on what you mean by 'better'.
Of course it is OK to overwrite an XML file. But if you want files that can be hand-edited by the user (think Notepad), .properties files are the way to go.
Cheers,
Vikram.
