.NET Class Library[^]
Each method is documented with the types of exceptions it throws. For example, the documentation for the Random class's Next(int maxValue)[^] method states that it will throw an ArgumentOutOfRangeException if maxValue is less than zero.

Hi Leslie
The .NET Class Library is what I'm looking for. I guess I will have to get use to the different way of dealing with code that causes exceptions.
Thanks heaps for you help
Cheers

You could use reflection to view the methods. You can also catch Exception, which catches all. You should avoid this. Generally, the exceptions will be obvious ( FileNotFound for a delete method, for example ).

Other than looking at the documentation (and trusting that it has been fully documented) there aren't any tools (at least none that I'm aware of) that will generate a list of exceptions.
It would be possible using a tool like Reflector[^], but that would be a very manual process.

Visual Studio 2003 has this problem. However, Visual Studio 2005 does list the exceptions for the method call. Just hover your mouse over the method name for a moment.

 Hi
I think you can solve your problem as below:
Put All the statements of your method in a Try-Catch.
for example:
private void divisionOperator()
{
try
{
result = result / x ;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}

Thanks for your reply
Not really a good idea to use a catch all exception if you don't have to. Better in this case to use a NumberFormatException (from memory). Catching a plain exception can cause other problems like hiding an exception that you might not have thought possible to throw.
For better explanation have a read of this article: Exception Handling Best Practices in .NET[^]

I think it's a shame that checked exceptions weren't implemented in c#. I love them.
Here's a link that discusses why they were left out of c#

hi,
I don't know where your database located. If your db is in server machine using SQl server, you must provide an accessing permission in Enterprise Manager with Security item.
It seems to be a solution.

I have an application that loads a specified web page that it have a button i.e with label 'OK'.I need to know how can this button get clicked from my app without user doing this.

Try looking at firing the event or even just calling the method that would be called by the button click.
Why do you want to simulate a button click?
If you want to simulate a button click then you might need to look at firing a mouse click event.
Hope that gives some direction.

Pls give me the code to create a mail merge application using Asp.NEt & C#
let the noble thought come from every side-Rig Veda

|

2 questions
1.) Why are you trying to create a mail-merge application in .Net when Word and Excel and Outlook will do things like this for you anyway?
2.) Why do you think someone is going to write this for you from scratch?
Try some part of it and when you get stuck ask how to get past that point - there are hundreds and thousands of programmers on here who will be more than happy to help you but only if you help youself to begin with....

Hi There Every Body,
I have a Form that its ctor defined like this :
public FrmOrder(Order order)
{
}
which "Order" is a predefined class.The object "selectedOrder" is an instance of class "Order".
Why Does this call change "selectedOrder" ?
FrmOrder frm = new FrmOrder(selecredOrder);
frm.ShowDialog();
Kind Regards : Ali
|
|
|
|
|
Because an Order is a class, and therefore a reference object. You pass the reference to the object, so there may be many variables all referencing the same physical object. So call a method on one reference that makes a change and everything that has the reference will see the change in the object.
This is different to a value object. In this case a copy of the object is passed, so if a value object is passed into a method then the code inside the method sees a copy of the object, rather than the version that was passed in.

Thanks Colin,
Whould u please tell me how should I Pass that instance By Value?
And what is the usage of "ref" keyword?
Thanks again.
Yours Sincerely. Ali

You can't.

To pass a value type by reference, such as an int.

there is a very subtle use for the ref keyword for objects.
You are saying that you pass the reference by reference.
If you assign an object to a reference you have passed in by val, the reference is not altered when you return from the function. If you pass it in by ref then the reference will be updated on your return
Hope this makes some sense

private void button1_Click(object sender, EventArgs e)<br />
{<br />
TestClass newClass = new TestClass("Initial");<br />
Console.WriteLine("Value after initialisation: " + newClass.TestValue);<br />
DoStuffByVal(newClass);<br />
Console.WriteLine("Value after byval: " + newClass.TestValue);<br />
newClass = new TestClass("Initial");<br />
Console.WriteLine("Value after initialisation: " + newClass.TestValue);<br />
DoStuffByRef(ref newClass);<br />
Console.WriteLine("Value after byref: " + newClass.TestValue);<br />
}<br />
private void DoStuffByVal(TestClass testObject)<br />
{<br />
testObject = new TestClass("Changed");<br />
}<br />
private void DoStuffByRef(ref TestClass testObject)<br />
{<br />
testObject = new TestClass("Changed");<br />
}<br />
class TestClass<br />
{<br />
public string TestValue;<br />
public TestClass(string testValue)<br />
{<br />
TestValue = testValue;<br />
}<br />
}
produces the following output
Value after initialisation: Initial
Value after byval: Initial
Value after initialisation: Initial
Value after byref: Changed

if it's the kind of object that you are likely to need to pass by val you should consider making it a struct instead. I'm thinking of classes like vectors, phone numbers etc which are often better as structs.

Hai I had a problem of exporting gridview control(or)dataset to exel sheet.So can u plz provide code with namespaces
|
|
|
|
|
I created simple DialogBased Windows application using C#
I want to check if user has entered any control characters in the edit box.
For Ex: in the edit box user can enter value like
ALT + 8 (BackSpace)
ALT + 9 (Horixontal Tab ) etc
Though it looks funny but I want to discard this input.
I tried to convert the string to int and check ASCII it did not work
EX:
Int32 nLength = str.Length;
for(int i=0;i<nlength;i++)
{
int asciival="System.Convert.ToInt32(str[i]);"
if(asciival="" <="" 33="" &&=""> 0 )
Discard the input;
}
In this scenario for ALT + 8 I get asciival as 9688
ALT+9 as 9675.
This is to check whether control characters entered?
Why do I get ALT+8 as 9688 not as 8 asci value ?
I want to basically check if user has entered any control characters
like 1-32 or 127 ASCII value (Ex: ALT + 127) in the edit box. And discard the same.
FYI this edit box should allow any other non english characters like French, German, Chinese, Japanese etc
