View 3 RepliesMy app runs perfectly with debug but I'm having a couple of little problems with the actual build on another machine.'m getting a "safe handle has been closed" (most of the time, but not all the time) when I button click out of a certain area.The problem, no doubt, is related to the serial port and I think I can solve it but I do want to ask something very basic....I have several points in the code where I'm doing a serialport.open and serialport.close....and clearing some registers etc.....like I say, in debug all is well.
View 4 RepliesI am trying to calculate the number of years for my calculate age event handler, however i am apparently missing a method or whatnot because im trying to calculate the age , can anyone suggest help on this. I need to subtract years to get my age but when i try the birthdate.Subtract (currentDate) method i get an error about not able to convert from LONG?
So below is what I have.

I use the following columns stored in a SQL table called tb_player:
Date of Birth (Date), Times Played (Integer), Versions (Integer)
to calculate a "playvalue" (integer) in the following formula:
playvalue = (Today - Date of Birth) * Times Played * Versions
I display upto 100 of these records with the associataed playvalue on a webpage at any time.
My question is, what is the most efficient way of calculating this playvalue given it will change only once a day, due to the (today-date of birth) changing? The other values (times played & versions) remain the same.
Is there a better way than calculating this on the fly each time for the 100 records? If so, is it more efficient to do the calculation in a stored proc or in VB.NET/C#?
