How do I implement this method?

Don't implement it that way. Exceptions should be used only for exceptional circumstances, not part of normal code flow.
Rather than doing that, either us a MaskedTextBox (new in .NET 2.0) or use a regular expression to validate the input.

When using Framework 2.0 you could use MaskedTextBox.

Include the Visual Basic library and use the IsNumeric method.

Here is an easy way that doesn't rely on exceptions, regular expressions, or legacy VB libraries:
double numericValue;
bool isNumeric = double.TryParse(myTextBox.Text, out numericValue);

Unfortunately there's no int.TryParse method to accompany that one.

Yes, there is an Int32.TryParse().
...or, at least I hope so, because I've used it...

Fortunately there are:
<br />
Int16.TryParse(string s,out short result)<br />
Int32.TryParse(string s, out int result)<br />
Int64.TryParse(string s,out long result)<br />

Thnax for all the input peeps..I am going to try the Int32.TryParse..Btw, what is the best resource for knowing all in the classes and methods ( other than MSDN help )? I don't expect to know them all, but it would be good to have a good reference other than Google...
And Judah's reponse is for keytrokes that are between 0-9, correct?

Ahhh..I am using 2003...Int32.TryParse i not available for 1.1, and 2003 doe not support 2.0 from what I know, Corret?

Try this.
text box's KeyPress event
if ((int)e.KeyChar >= 48 & (int)e.KeyChar <= 57)
OR
in KeyDown or KeyUp event
if (e.KeyCode >= Keys.D0 & e.KeyCode <= Keys.D9)
this.Text = e.KeyValue.ToString();
Best of Luck.

hi

Hi,
I have a question related to passing an array to a method.
In C++, if I have an array Arr[] with 20 elements, and I want to pass the array to a method, but starts from the 10th element, then I would do the following:
AMethod(Arr + 10);
If I want to do the same thing in C#, what would be the proper way? Thanks a lot.

Pass the offset and length. It is always a good practice.

Use the System.ArraySegment generic class.

Friends,
In Winforms, the control gets highlighted when it has an input focus either by pressing TAB key or by clicking it with mouse. Now what i want is that my button control should not get highlighted when it has an input focus. How can i do so ? Is there any property ?
