You could create controls and space them using the various formatting controls available in the ToolBox. A Table that holds controls is a good bet since that is what the spreadsheet layout is. I am not sure about what form layout controls are available in CSharp but the TableLayoutPanel and a couple of others are available in Vb.net. If you are talking about printing I am not sure since I have done little with printing to paper. If you want to format the data inside the TextBox as you are now doing you will use things like the, in VB, the Spaces object and the line feed enumerations to format the textbox contents. It depends on the job requirements.

Hi,
Do you know if there is a component in which I can write the data into, that
would make the report look like a excel spread sheet?  Or do I have to
manually align everything?
Currently I am writing to a rich text box.

Once again, thank you,
Celia

Look in your ASCI table and determine what the EOF character is then search
for it - if you're going to do it that way rather than the way Tyler does
it.

Cheers,

Hi,

The thing is that I dumped all of the file into a string.  I am reading
the
string character by character checking for ",".
So when I reach the end of the string I am crashing.   Is there something
for end of the string?
It is a very small file, maybe, about 5 records.

Thanks,
Celia

Also so that I could

There is a character at the end of the file...  might be 0x20?  Don't
remember off hand, but I'll bet there's a table at the end of your book.

Hi again,

Thank you for your suggestions.
I was able to write and read to a file.  Just one more thing, how do I
check
for end of file?
I have to read the file and print the data onto a report.

Thank you,
Celia

Hi Again: If you are going to be writing often to your file you will want
to

use the
FileInfo Class instead of the File Class. It is pretty much the same
except
that it is an instance class, it does not require a security check every
time it is called and can be made threqad safe me thinks.If you are just
logging errors or something that you don't care about performance with
then
the File class is the way to go since you will not have to instantiate
the
class in your code but it will run slower.

Hi:
First, I don't think I saw your file type, the ".txt" file type
extension
in the file path for your file if I remember and that would throw an
exception. Below is the MSDN Doc stuff I pulled from the File Class
Definition that I thought might help. The complete document can be found
at:
http://msdn.microsoft.com/en-us/library/ms143356.aspx
if you want to read up on the File Class.
Here is the copied stuff for the CSharp version:
Copy
using System;
using System.IO;
using
System.Text;
class
Test
{
public static void
Main()
{
string path = @"c:\temp\MyTest.txt"
;
// RtNote, notice the .txt file extension in the above file path
// Also, note the use of the @ sign as Jamal identified in a prior post.
// This text is added only once to the file.
if
(!File.Exists(path))
{
// Create a file to write to.
string createText = "Hello and Welcome"
+ Environment.NewLine;
File.WriteAllText(path, createText);
}
// This text is always added, making the file longer over time
// if it is not deleted.
string appendText = "This is extra text"
+ Environment.NewLine;
File.AppendAllText(path, appendText);
// Open the file to read from.
string
readText = File.ReadAllText(path);
Console.WriteLine(readText);
}
}

In C#, you do not have to double the backslash characters if you
precede
the string literal with the @ symbol. Just put that symbol immediately
before the initial quote mark.

Hello,
you need to escape your \ by doing \\. So, it'll look like:
C:\\myfolder1\\myfolder2...

Hi Varun,

I tried writing to a file, but the comiler does not like the ?
\.  The following is what I coded.
File.AppendAllText(C:\Documents and Settings\celia\My
Documents\Visual
Studio\Projects\TestCode,Data);

It gives me an error on the \.  Do you know what I need to do so it
will
except the \?

Thanks,
Celia
