message box... check date / time

[tmashley]

Hi all,
as you can't display a message box using vb.net, i have had to use javascript...

i am using a Popup Calendar that sent the value of text boxes to the dates selected
i need to make sure that the end date is after the start date.

this is what i am doing at the moment...

function CheckTime(){
if (document.CRC.txtStartDate.value >= document.CRC.txtEndDate.value){
var ErrMsg = "End Date Must be later than Start Date";
alert(ErrMsg);
return false;
}
}

the problem is; example
StartDate = 23/12/2003
EndDate = 13/11/2003

the code thinks that beacuse the first number is greater, then the whole number is, so it doesn't work.

please help.
Thanks
Tom

java.util.Date; public int compareTo(java.util.Date anotherDate)

Also passing a String to a Date constructor will flag a warning. Not sure why they they deprecated it though.

  import java.util.*; 
 
  public class X{
  private Date start;  
  private Date end;
  
  public X(){
     start = new Date(20911); //  public Date(int year, int month, int day) deprecated
     end = new Date(20921); // public Date(String s) deprecated
     dateChecker(end);       
  }

   public static void main(String[] args){
     new X();  
   }
 private void dateChecker(Date end){
  int i = start.compareTo(end);
  switch(i){
   case -1:{System.out.println("start is before end");}
   break;
   case 0:{System.out.println("Same dates");}
   break;
   case 1:{System.out.println("start is after end");}
   break;
  } 
 }
}

You're in the wrong forum. This is Java. You want JavaScript.
