Catch exception help please

Question

Doing simple date work and trying to validate a date. this.Label1.Text=Bad Date was attempted; private void TextBox1_TextChanged(object sender System.EventArgs e) { try { Convert.ToDateTime( this.TextBox1.Text.ToString()); } catch(Exception ee) { this.Label1.Text=Bad Date was attempted; } What is the catch() expression to catch a bad date like 18/31/2004 Exception ee is missing it? TIA

Missing the obvious here...you are not even using the return value of the Convert.To call so this can not work even if the date entered is valid.....

try the generic catch statement: catch { ... } As for this line of text... Convert.ToDateTime( this.TextBox1.Text.ToString()); You're not assigning the DateTime to anything which is probably the problem. Try this: DateTime inputTime; try { inputTime = Convert.ToDateTime( this.TextBox1.Text ); }

Try to catch specific exception i.e. FormatException (if value is not a properly formatted date and time) ArgumentException (if value is null) and OverflowException (if value represents a number less than MinValue or greater than MaxValue).

My users and I hate having to use the mouse when you can put in a date so much easier and when you have to do it for a future date curdate()+15 or +30 or +45 the datepicker is slow and unproductive. Thanks for the reply though.

hi i donnot know but i think that it is not implemented ..........u need to make a function to test that slected date not exceeding current date also i see that u didnot even use the exception ee............. u could use it like this this.label1.text=ee.Message.ToString();
