Is there any return statement in "SpecialCleanup()" method also am assuming that the exception could be from SpecialCleanup() method only so you are not able to figure out what was the original exception.
I would suggest that you log the stack trace as soon as the exception is raised !!! Use exception handling block and logging block provided by MS ...

Assuming that you are creating a windows application, change your project settings to Console application (won't change anything in your programm, only you will have console window available for debugging purposes).
Check this:
try
{
Something();
}
catch (Exception e)
{
Console.WriteLine(e.ToString());
SpecialCleanup();
}
finally
{
NormalCleanUp();
}

You are running in to a problem known as "breaking the stack", which is why the exception doesn't have the relevant stack trace data. You were on the right track, but need to change the code so it looks like this:
catch(Exception ex)
{
SpecialCleanup();
throw;
}The difference here is that throw ex; throws a new exception where throw; re-throws the original exception.
That being said, you really should try to avoid catching general exceptions and catch specific exceptions that you know you can recover from. What is the difference between SpecialCleanup and NormalCleanup?

thanks for the tip, I'll try that tomorrow!
the relevant objectis an UndoManager.
in case of exception the special cleanup remove all action, i.e. there is no any undo action anymore.
This way, if someone cath up the exception higher the hierarchy he know he would be safe from corrupted undos... (there would be nothing left to undo!)

Try adding $exception to the Locals window.

hi,
thank u for u r response..
Error i am gettign is:
"The & character,hexadecimal vale 0x26 can't be included i a filename"
I am storing some values in an XMl file and i am passing Filename as parameter of a method.
Not by SaveDialogControl.
Through code. And if I give the correct file name it is saving as a xml file.
But if i give pass extra chracters to a file name through method.
It is giving errror like.
"The & character,hexadecimal vale 0x26 can't be included i a filename"

That is fine but my question is why to want to store a file name with special character as most of OS doesn't allow that !!!

Hi,
Is is possible to add user defined compiler errors to CompilerError class.
My requirement is while compiling my file, using codeDomProvider,
I want to Check for the presence of Special Characters in timername. If it
is there a compilerError should be raised.
forexample,
if my file contains a line like
setTimer(timername);
and if timername contains any special characters, that should be
deducted while compiling. I want to add that error to compilerError Class
How can i do that.
Sakthi.

My gut feeling says that you can't code a user defined compiler errors as this means you are try modify .NET compiler which MS doesn't allow

I am newbie at this, please try to be patient with me. In my class at school we have been trying out various loops in problems. The instructor calls the one we've been using a "Sentinel Loop". If there is another name for it I don't know what it is. 
 I can get it to accept the input and also the stopping statement. I can even get the program to tell me the sales tax and shipping "on an individual input".
The instructor wants to be able to input several figures and when the stopping statement is triggered, have the program show the total shipping cost and sales tax for all of the inputs together.
I have placed the math parts between the two input statements, and also outside of the loop.
My question is: "Do I need to put the math section into a method and if so where would I place the calling statement so that it would only work after the stop statement is triggered or would something else be even more appropriate?" 
I have been beating my head against the wall for the last 10 days, and have not figured out an answer. I have tried everything I can think of. 
Can someone either please answer the question or at least steer me to the information on how to do this type of a problem. I would appreciate it greatly.
This is the main body of my sentinel loop program. I can get it to work fine.
using System;<br />
using System.Collections.Generic;<br />
using System.Text;<br />
<br />
namespace Exer4Chpt6<br />
{<br />
class Program<br />
{<br />
static void Main()<br />
{<br />
string inValue = "";<br />
double salesAmount = 0;<br />
double salesTax;<br />
double shipAmount = 0;<br />
double grdTotal;<br />
const double INTEREST_RATE = .07;<br />
double overAllTotal = 0;<br />
double totalShippingAmt = 0;<br />
double totalSalesTax = 0;<br />
<br />
Console.WriteLine("Enter as many different sales amounts ");<br />
Console.WriteLine("as you want. You will be shown the sales ");<br />
Console.WriteLine("amount, sales tax, shipping amount, and ");<br />
Console.WriteLine("the grand total. To Stop, enter");<br />
Console.WriteLine(" -99");<br />
Console.WriteLine();<br />
<br />
Console.WriteLine("Please type in a sales amount.");<br />
inValue = Console.ReadLine();
while (inValue != "-99")<br />
{<br />
salesAmount = Convert.ToDouble(inValue);<br />
salesTax = salesAmount * INTEREST_RATE;<br />
<br />
Console.WriteLine("Please type in a sales amount.");<br />
inValue = Console.ReadLine();
}<br />
}<br />
}<br />
}<br />
This is the math section of my program that I'm having the trouble with. The problem isn't in the math expressions themselves, but more in the placement to get it to do what I want.
if (salesAmount < 250.01)<br />
{<br />
shipAmount = 5.0;<br />
}<br />
else if (salesAmount < 500.01)<br />
{<br />
shipAmount = 8.0;<br />
}<br />
else if (salesAmount < 1000.01)<br />
{<br />
shipAmount = 10.0;<br />
}<br />
else if (salesAmount <= 5000.00)<br />
{<br />
shipAmount = 15.0;<br />
}<br />
else if (salesAmount > 5000.00)<br />
{<br />
shipAmount = 20.0;<br />
}<br />
else<br />
Console.WriteLine("Please type in a sales amount.");<br />
<br />
grdTotal = salesAmount + shipAmount + salesTax;<br />
overAllTotal += grdTotal;<br />
totalShippingAmt += shipAmount;<br />
totalSalesTax += salesAmount;<br />
Console.WriteLine();<br />
Console.WriteLine("Your final sales amount was: {0:C2}", grdTotal);<br />
Console.WriteLine();<br />
Console.WriteLine("Your sales tax amount was: {0:C2}", totalSalesTax);<br />
Console.WriteLine();<br />
Console.WriteLine("Your shipping amount was: {0:C2}", totalShippingAmt);<br />
Console.WriteLine();<br />
Console.WriteLine("Your total bill is: {0:C2} ", overAllTotal);<br />
Console.WriteLine();
Any help will be very greatly welcome. Thank you.

I was able to recheck on these type of loops and found a solution. By placing the math section after the final input I've got it to work correctly. I placed the math section in the spot shown below.
<br />
salesAmount = Convert.ToDouble(inValue);<br />
salesTax = salesAmount * INTEREST_RATE;<br />
<br />
Console.WriteLine("Please type in a sales amount.");<br />
inValue = Console.ReadLine();
}<br />

Hi All,
Anybody knows why main() is called as main?
Why not someother names but Main()?
Anticipating your responses.
Thank You,

Its name based on its compiler ,
If compiler is editable, you can change it to whatever you like ,

My feeling is that Microsoft wanted to have its own way of specifying the single entry point to program. And wanted to get away with traditional way !!!

The name comes from C, where the function that holds the code for the main program is called "main", so the name has been around for at least 30 years.

I am using RichTextBox class to display some text, and then I want to syntax highlight whats written to it.
So, i use Find(...) to select required text and then use SelectionFont,SelectionColor to changle font/color of the words i need.
The problem is that when i type, i have to do this when the text changes, and i actually see how text gets selected and changes it's color, and that is very annoying...
So, my question is, how to solve this problem? Maybe i can somehow disable redrawing of control till i completely highlighted control or smthing like ?

Hi EveryBody,
We know that Delegate is a Functional Pointer. But i want to pass Member name as a variable to Delegates. The example given below.
*--------------------------------------------------------------------------
using System;
namespace Delegate_concept
{
public delegate void MyFunction(int a, int b);
class Delegate_Method
{
public static void Function1 (int x, int y)
{
Console.WriteLine("Sum is"+(x+y));
}
public static void Function2 (int x, int y)
{
Console.WriteLine("Sub is"+(x-y));
}
public static void Function3(int x, int y)
{
Console.WriteLine("Mul is"+(x*y));
}
static void Main(string[] args)
{
int i = 1;
string Fstring = "Function";
string nString;
for ( i=1; i<=3; i++)
{
nString=Fstring+i.ToString();
MyFunction mObj = new MyFunction(@(nString));
mObj(20,5);
Console.Read();
}
}
}
}
*------------------------------------------------------------------------
In the above example, i am storing each function name into "nString" variable.
While creating instance, can i pass this variable name as a parameter. Because the variable name contains name of the function. Or i want to evaluvate the variable nString and execute the function name which i stored in "nString" variable.
If any solution or suggession please write to: act_ramesh@yahoo.com
Thanks

Constructor MyFunction mObj = new MyFunction(void (int, int)target);
expects a target == method . You cannot provide string instead of method itself.
If you really want to call those methods by their index(Function1, Function2,...) , put them into a List<myfunction> or Dictionary<int, myfunction=""> :
Dictionary<int, myfunction=""> dFunctions = new Dictionary<int, myfunction="">();
//or
List<myfunction> lFunctions = new List<myfunction>();
//fill list/dictionary
...
//call method
for ( i=1; i<=3; i++)
{
dFunctions[i](20,5); // or lFunctions[i](20,5);
Console.Read();
}
