The IsNumeric Function Checks for numeric value.
private void txtPortNo_KeyPress(object sender,System.Windows.Forms.KeyPressEventArgs e)
{
int KeyCode=(int)e.KeyChar;
//Check whether the value is alphanumeric
if(!IsNumeric(KeyCode))
e.Handled=true;
else
e.Handled=false;
}
private bool IsNumeric(int Val)
{
return ((Val>=48 && Val<=57) || (Val == 8) || (Val ==27));
}
To check for IP number the function is given below
private bool IPDotNumeric(int Val)
{
return ((Val>=48 && Val<=57) || (Val == 8) || (Val== 27)||(Val==46));
}
So with this Idea we can customize the Functions to our need.
