Use a mono spaced font and pad you text
Use a proper label printing tool

There are a number of problems there, such as this:
for (int x = 0; x < NUM_DASHES; ++x) ;
Which does nothing.
And the very wasteful way you are assembling strings: they are immutable, remember, which means that each time you add two strings, you create a new, bigger string and copy both originals into it. You should consider looking at StringBuilder if you are going to do that in future.
But...as Mycroft said, a monospaced font and manual padding will work.
I just wouldn't do it.
Instead, I would use a DataGridView to display the data - it's a lot prettier, a lot more flexible, a lot friendlier for the user, and once you are used to it a lot easier to use.
Try it! Drag one onto your form, and give it 5 columns, with appropriate headings.
Then just add rows - MSDN will help you with an example.

I agree with OriginalGriff if you don't have to output in a cmd window eg. try using a grid or listview or something.
aligning text into columns is not as easy as it looks.

Add an event handler for the function you wish to capture: CellClick, CellDoubleClick etc. You can do this in the properties window of the DataGridView, or just double click in the cell in the Form Design window in Visual Studio.
Veni, vidi, abiit domum

Create a cell click handler dynamically:
dataGridView1.CellClick += new DataGridViewCellEventHandler(dataGridView1_CellClick);
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
}

When i try to deserialize hexadecimal value it throws following exception?
hexadecimal value 0x03, is an invalid character.
While i am trying serialize ascii charactors it's not providing any type of issues,but when i try to deserialize it throws above exception.How to solve above issue?
Here i have attached sample project PFA.
https://skydrive.live.com/redir?resid=4A762A0B7460096A%21171
In above sample project ,i can able to serialize the input data but after serialization successful i can't do deserialization ,it throws some exception.Please give some solution .If unable to deserialize hexadecimal to ascii from serialized data means why should you allow to serialize the ascii characters?

I don't think anyone is going to download your project. It would be better to post the relevant code here.

What's in your file that you serialize is not a representation of a hexadecimal value: it's the character-code "3," which is turned into a glyph when you see it on screen that looks like a super-scripted tiny "L." The CodeProject editor here will not display that character-code.
The writing process, whether you use StreamWriter or XmlWriter, cannot know your intent from such "raw" use of character codes outside the usual range.
The solution is to express your intent that the content is hexadecimal by using an Xml "legal" data format like
1#x3;: a
2#x3;: s
3#x3;: d
4#x3;: f
5#x3;: g
Which will serialize (if you use an XmlWriter) to:
<?xml version="1.0" encoding="utf-8"?><TestClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><No>25</No><Name>TestUser</Name><Address>No 4,East St</Address><AsciiCharactors> 1#x3;: a
2#x3;: s
3#x3;: d
4#x3;: f
5#x3;: g</AsciiCharactors></TestClass> The legal formats for Xml are provided in this document: [^]. Note the following:
"If the character reference begins with " &#x ", the digits and letters up to the terminating ; provide a hexadecimal representation of the character's code point in ISO/IEC 10646. If it begins just with " &# ", the digits up to the terminating ; provide a decimal representation of the character's code point." If you used the format " &#x??; ":
... not able to display that format correctly using CodeProject's editor ...
You would get this as output (using XmlWriter):
<TestClass xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><No>25</No><Name>TestUser</Name><Address>No 4,East St</Address><AsciiCharactors> 1: a
2: s
3: d
4: f
5: g</AsciiCharactors></TestClass>

No it isn't; it's a Ctrl-C. I've had to deal with that at times -- generally you can just filter out characters like that before trying to process the data.

Dear friends and Bosses...
I am Arif. I am very new to programming world. Trying to make my 15 years old dream come true. Becoming a developer.
1. I have a very little knowledge about C. Never developed any application.
2. Want to become a Web developer then App developer.
3. Want to learn C#.
I am very confused about OOP. And so about C#.
Is there any book or website or reference about anything that tell me the similarities about C and C#.
Like USING SYSTEM in C# is as same as #include <headerfile.h>...
and also any very easy to understand book for C#... that explains everything including the c# terminologies like INSTANCE, METHOD, BUSINESS CLASS....like that...please....thanks a lot.

They're exactly the same except for the parts that are different.
Member 10583150 wrote: Like USING SYSTEM in C# is as same as #include <headerfile.h>...
No. In C# using directives are optional, but in C you won't be able to do much without including header files somehow.

thanks a lot for your reply. that INCLUDE was an example. but is there book or website or youtube vdo do you know where i can learn c# from. I do not have any OOP idea. at all. its it is very confusing. the terminologies are extremely hard for a beginner. and i donno why none explains it properly.

Which are most of them, especially the ones that look the same.

The free e-book, .NET Book Zero[^] by Charles Petzold, is a very useful starter.

To add to the other examples, stop trying to compare C and C#: they are completely different languages which happen to share a similar looking syntax If you assume that all you need to know are "the differences" that you are going to get a completely wrong idea about C# and it will not work well for you.
If you want to learn C#, forget all you know about C - it will only confuse the issue. And get a good book (or a training course if you can) and do it completely, starting from the beginning and doing each and every exercise.
You've had some suggestions, and this is another: Pro C# 5.0 and the .NET 4.5 Framework
http://www.amazon.co.uk/Pro-NET-Framework-Professional-Apress/dp/1430242337[^] - I learned C# from one of the earlier incarnations of this and it covers the material well.
Might be a little heavy duty for a complete beginner to computers though!

Hi All, im having the following problem with a project.
Im trying to use the following (for a search bar button) to pull data from the Product table I have in my SQL db. However when I hit the search button, I get an error with the conn.Open() line
protected void btnsearch_Click(object sender, EventArgs e)
{
SqlCommand search = new SqlCommand("spSearchProductByName", conn);
search.CommandType = CommandType.StoredProcedure;
conn.Open();
search.ExecuteNonQuery();
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = search;
DataSet ds = new DataSet();
da.Fill(ds, "ProductName");
gvSearchResults.DataSource = ds;
gvSearchResults.DataBind();
conn.Close();
Any help would be appreciated

Remember, we're not mind readers and can't see your screen. So we have no idea what "error" you're receiving. Have you tried initializing conn? Also, wrap your code in a try/catch block so you can inspect the exception and thereby identify the problem.

Since you get an error when trying to open the connection, the most likely things are that:
1) You haven't initialized the connection string into the SqlConnection object
2) Your connection string is wrong.
So use the debugger, look at the connection and at the error object and see what it says. Then check your connection string. Chances are it's not valid - it could be your username is wrong, or the PC instance. But we can't tell from here!

Other possible errors
- Database isn't up
- Database isn't accessible from current location.

I find for example: create lines running up the pannel, how can you share yourself with.

Hi everyone,
I'm currently working on a path finding project in C#. I do have experience with the C# language but the concept of AI such as path finding is pretty new to me. I have been following a couple of tutorials but I'm struggling to get my head around the subject. Can anyone recommend/point me to some tutorials or resources that would be suited towards beginner levels?
Thanks in advance!
