hi
i'm facing a problem with the client side time calculation.
i must calculate two different time hours and minutes to get the total time
for example from 12:00 till 15:00 the result must be 3:00

NB:
the from must be runat server "runat = server"

Can you further define your question? Are you trying to make this code run on the client or the server? There are numerous methods for doing time math on the server, but not so many on the client.

WELL OK
I HAVE 2 FIELDS WHICH ARE "FROM TIME" AND "TO TIME" I WANT TO CALCULATE THE TOTAL TIME WHICH IS THE DIFFERENCE BETWEEN THE "TO TIME" AND THE "FROM TIME" AS CLIENT SIDE. WHICH MEANS WHENEVER THE USER FILL THE 2 TEXTBOXES IN THE THIRD TEXTBOX WHICH IS THE "TOTAL TIME" WOULD BE DISPLAYED AUTOMATICALY.
IS THERE ANY WAY TO DO SO?
THE RESULT OF THE CALCULATION MUST BE IN A TIME FORMAT.

THANKS

a simple google reveals :

Thanks for this link it was so interesting but i'm still facing a problem becasue as you know i'm working on an ASP.NET application the textboxes are "runat = server" controls with those controls the javascript function is giving me an error which is:
"textbox1 is null or not an object"
i'm trying to get the time or date value from textbox1.
so is there any additional or any other code that might work with asp.net server control textboxes?
thanks
