// In C# 2.0, you can use the default keyword.
this.textBox1.PasswordChar = default(char);

i can't use default(char), maybe i've not c# 2.0 becouse i'm in VS.NET 2003

Yeah, in VS 2003, one can only use .NET 1.1. All you need to do is set the PasswordChar property to whatever is the default value for a character. I believe the default character value is '\0'.

I use this:
txtPassword.PasswordChar = '\0'; and it works in .NET 1.x.
I hope it helps!

I'm wondering is there a way to add my own link to the default page that users see when going to the webservice in a browser. I'd like to be able to link to a document (or pdf, or html page) with better specs on the webservice than just the descriptions that you can supply in the WebMethod's Description attribute.

Hello,
I am trying to store boolean expressions such as "((_ltv >= 80) && (_escrows == 2))" in a SQL Server Table. The objective is to open up the table from C# and pass these expressions into a parameter named "_reason" so that _reason contains the expression described above. Then using the method below to test if the conditions in the expression are true. If the expression is true, then to return the amount of the adjustment assigned in the record for that particular expression or condition.
private void testCondition()
{
try
{
if (_reason)
{
MessageBox.Show("The adjustment is \n" + _adjustedPrice.ToString());
}
}
catch(Exception ex)
{
MessageBox.Show(ex.Message);
}
}

You can't store an expression in a variable. You can store it as text in a string, but then you have to parse it somehow to evaluate it.
If all expressions have the same form (comparing variables to a span of values), you can just store the spans for each variable and compare them.

Thank you for you response. I realize that the variable must be initially stored as a text expression and then somehow converted to a valid boolean expression. My question is how does one convert a boolean expression originally stored as text into a valid boolean expression that can be evaluated? Surely this must be possible somehow. Actually I had success hard-coding the expression to an object and then converting to boolean as detailed below: The catch is storing this "object" expression in SQL and then loading it into the object variable and then converting the expression from an object to a valid boolean expression
If C# allows the following expression to be used in an "if" statement then there must be someway to convert the expression from a text to a boolean.
This works:
object _condition = NULL;
_condition = ((_loanPurpose < 3) && (_programGroup == 3) && (_approvalLevel == 8) && (_agency == 1) );
bool _reason = false;
_reason = Convert.ToBoolean(_condition);
if (_reason)
{
_adjustPrice += -1.000;
}
Is there a way to store an object that looks like the expression above in a SQL fields and then loading into an object variable to be converted to a boolean expression like above?

The object that you have created doesn't contain what you think it does. The expression is first evaluated, then the result (a boolean) is boxed into an object. The reason that you can convert it to a boolean is that it already is a boolean.
Evaluating an expression is a bit more complicated than that. Look at this example: Compiling C# Code at Runtime[^]

Isn't that what debugging mostly is? You write code, you try it out, an error is generated, you examine the value of the variables, the objects, take note of the exeption that was thrown and try again setting a breakpoint somewhere before the error to see the flow of the application to determine why it went wrong.
Then once you understand that you write a unit test to ensure that code path has a test, if it didn't already, so that if the error rears its ugly head once more then you see it instantly in the unit tests.

Have a look at the MSDN Nuggets videos on debugging. There's one called "Tools for Debugging" or something like that. There's a whole section just on VS 2005 debugging. But some of it is applicable to VS 2002/3 debugging too. You will get some ideas from watching a few of them.
