This is a waste of time, you assign the variable to a different array in the next line
Your code is very messy. It should use stringbuilders instead of concatenating strings.
You should experiment with known strings until you find one that shows your bug, then step through the debugger to see what's going wrong.

Hi,
some suggestions:
1.
when showing code, put it in PRE tags so it preserves indentation; as it is,
it is very hard to read.
2.
your code does not compile; it has:
- a String.Split with lower-case
- the line int currentLine Length = 0; is invalid
- a mismatch in { and }
etc
3.
you are trying to do word wrap yourself; why don't you use LastIndexOf(' ',maxLength)
where maxLength is your linewidth limit, to find where the offending word begins?
4.
you have a lot of \r\n; I believe in RTB a single \n is what is required for
line breaks. It is my guess those \r will be turned somehow into spaces,
resulting in some of the phenomena you are experiencing.
The above list is not complete.

Hello Everyone...
I have a question about two form want to access global variable
like below, i create three classes, main class and two inner class,
but i don't why couldn't compile successful ?
If I want do this how should i to do?
<br />
namespace Innerclass<br />
{<br />
class Program<br />
{<br />
public string Share1 = "Share_Temp1";<br />
public string Share2 = "Share_Temp2";<br />
static void Main(string[] args)<br />
{<br />
object obj = new object();<br />
obj = Program.<br />
}<br />
class ClassA<br />
{<br />
public ClassA()<br />
{<br />
<br />
System.Console.WriteLine("Class A Constructor init.");<br />
System.Console.WriteLine("Class A Constructor init.--" + Share1);<br />
System.Console.WriteLine("Class A Constructor init.--" + Share2);<br />
}<br />
<br />
}<br />
class ClassB<br />
{<br />
public ClassB()<br />
{<br />
System.Console.WriteLine("Class B Constructor init.");<br />
System.Console.WriteLine("Class B Constructor init.--" + Share1);<br />
System.Console.WriteLine("Class B Constructor init.--" + Share2);<br />
}<br />
<br />
}<br />
}<br />
}<br />

in the code you sent,you must declare Share1 and Share2 variables as static members to work ,or pass an instance of Program class to ClassA and ClassB (is not a good choice for program class).
the only difference for inner classes in this usage is they can access the private members too.
here is the example from yours
namespace Innerclass
{
class Program
{
public static string Share1 = "Share_Temp1";
private static string Share2 = "Share_Temp2";
private string Share3 = "Share_Temp3";
public string Share4 = "Share_Temp4";
static void Main(string[] args)
{
Program prg = new Program();
ClassA clsA = new ClassA(prg);
ClassB clsB = new ClassB(prg);
}
class ClassA
{
public ClassA(Program prg)
{
System.Console.WriteLine("Class A Constructor init.");
System.Console.WriteLine("Class A Constructor init.--" + Share1 );
System.Console.WriteLine("Class A Constructor init.--" + Share2);
System.Console.WriteLine("Class A Constructor init.--" + prg.Share3);
System.Console.WriteLine("Class A Constructor init.--" + prg.Share4);
}
}
class ClassB
{
public ClassB(Program prg)
{
System.Console.WriteLine("Class B Constructor init.");
System.Console.WriteLine("Class B Constructor init.--" + Share1);
System.Console.WriteLine("Class B Constructor init.--" + Share2);
System.Console.WriteLine("Class B Constructor init.--" + prg.Share3);
System.Console.WriteLine("Class B Constructor init.--" + prg.Share4);
}
}
}
}
good luck

This obviously won't compile. What are you trying to do ?
AYR Chen wrote: I have a question about two form want to access global variable

Instead, your two forms should use delegates to communicate the variable value to each other as it changes, and get rid of the global.

Please show code using PRE tags (not CODE tags);
I can't understand it without proper indentation.

dear sir,
i want read an excel file and open it to listview but now two exception throws would u help me.....its very urgent.
exceptions:

1. No overload for method 'Open' takes '13' arguments
2. Property, indexer, or event 'Value' is not supported by the language; try directly calling accessor methods 'Excel.Range.get_Value(object)' or 'Excel.Range.set_Value(object, object)'

1 - use intellisense to find out how many arguments you should be providing, and fix your code
2 - call the get/set methods, as it is telling you to do

Is there a way to import a pre-written xsd document so I don't have to actually create the schema? With that, is there a way to reference an XML document you are creating at runtime to be referenced to the schema? Thanks in advance.

hi can anybody let me know is it possible to display child windows using threads or delegates?
thanks
|
|
|
|
|
why would you need to do that anyway?
just display the child window like this form1.Show(this) to make it a child window of the current window that;s it

These are two utterly, totally different things. The latter is trivial, the former is a bad move. You should never interact with UI elements outside of the thread that created them, which should, logically, be your main thread.

But I have a question about
if i want appear a form after pressing a button on main form
and main form will disappear, and when press a button on
child form the child form will disappear and the main form will
appear ? Does anyone know how to do?

just pass the main form to child form and then call Hide method of the main through child or before showing it (from the MainForm)
and you can do that vice versa for showing main again and hiding child
namespace Test2
{
public partial class MainForm : Form
{
ChildForm child;
public MainForm()
{
InitializeComponent();
this.child = new ChildForm(this);
}
private void hideAndShowChld_Click(object sender, EventArgs e)
{
this.Hide();
this.child.Show();
}
}
public partial class ChildForm : Form
{
MainForm main;
public ChildForm(MainForm form)
{
InitializeComponent();
this.main = form;
}
private void button1_Click(object sender, EventArgs e)
{
this.Hide();
this.main.Show();
}
}
}
good luck

What is it that you are trying to do? If you are trying to change where your compiled code gets stored after a build, you'll need to go into the project configuration and there you can change the path of your builds.

How to convert 070818 to 20070818? any one provide solution for me

add 20 to the front of it ? Your question isn't making much sense, I'm afraid. Do you have this as a number, or a string ? what's the hard bit, are you assuming all dates are in the past, or not ?

You can use DateTime.Parse or DateTime.ParseExact, and DateTime.ToString methods
and apply a "Custom DateTime Format String"
the format specifiers "y", "yy" and "yyyy" need your attention;
look it up on MSDN

I have that same problem, a log from a third party program begins each line with YYMMDD, so my reader class has
private static readonly string Century = ( System.DateTime.Now.Year / 100 ).ToString() ;
then when I read in a line from the log, I do
date = Century + line.Substring ( 0 , 6 ) ;

Hi all,
My requirement is "Comparing two versions of the same document (word)side by side graphically" .
In brief:
I have a DataBase table called "DocumentTable" that contains column fields "DocStatus" , "DocLocation" , "DocName", "Supercede"
'DocLocation' column field holds file location information
'DocName' column field holds name of the document
'DocStatus' column field tells the status of the Document (like '0', '1')
'Supercede' column field holds the information of previous version of the file
So, when DocStatus value is '1' then my application should get (dynamically) the current version of the file from the location specified in 'DocLocation' field and the copy of previous version stored in other location and then compare these two versions side-by-side graphically.
So all, please let me know if anyone has some idea about how to implement or any suggestions to proceed.
I appreciate your time and thanks in advance.
Note: If you have any doubts on my requirement please let me know..
Regards,
Krish.
