Can you explain a bit better what your asking?
Your program will execute the code within the try block, if an error occurs it will 'jump' to the catch block and execute the code there. It will not return to the try block.
If there is any code you always need/want to be executed use a 'finally' block.

I saw your Example code in Coding Horrors  lol
I dont know what your problem is but its not done that way, what is the is of using the catch keywork and not use it.
try
{
}
catch(ApplicationExeption ex)
{
}

Not sure what it is you want, however:
1.
there is no simple equivalent to ancient Basic's "On Error Goto Next"
2.
if your try block contains a loop, and fails in one iteration of said loop, anything in the try block is aborted, also the loop.
if you want the loop to continue with the next iteration, you have to turn things around, and put the try-catch construct inside the loop.

I am having trouble working out how i can make a beep occur for a given duration of time.
I have the following event handler that will recieve the beep duration and execute it for that amount of time. Lots of articles talk of beeping for intervals but have not found a way to make a continuous beep.
void VMCU_Beep(int BeepDurationInSeconds)
{
}
Does anyone know how this can be done
Thanx George

Use System.Console.Beep(frequency, duration)
Panic, Chaos, Destruction.
My work here is done.

The GridView columns are as follow:
<Columns>
<asp:BoundField HeaderText="ID No." DataField="NRIC" />
<asp:BoundField HeaderText="Name" DataField="LabourName" />
<asp:BoundField HeaderText="Event Name/Duty Roster" DataField="EventName/DutyRoster" />
<asp:BoundField HeaderText="Working Date" DataField="WorkingDate" />
<asp:BoundField HeaderText="Normal(hr)" DataField="NormalHour" />
<asp:BoundField HeaderText="Amt(N)" DataField="NormalRate" />
<asp:BoundField HeaderText="Extra(hr)" DataField="ExtraHour" />
<asp:BoundField HeaderText="Amt(E)" DataField="ExtraRate" />
<asp:BoundField HeaderText="Weekend(hr)" DataField="WeekEndHour" />
<asp:BoundField HeaderText="Amt(W)" DataField="WeekEndRate" />
<asp:BoundField HeaderText="Holiday(hr)" DataField="HolidayHour" />

For the love of God, tag your code so that its pretty:
------------|-------|---------------|-----------------|--------------|--------|---|------
LabourID |Name |Event Name |Working Date |Normal(Hr) |Amt(N) |...|Total
------------|-------|---------------|-----------------|--------------|--------|---|------
009 |ET | All | All | 5 | 35.0 |...|95.0

Then we can think about the problem.
The solution is not too hard and you needn't have posted 18 billion lines of code.

Can u give me solution? I need to accomplish it. Thanks.

I can give the solution but you'll learn morew by trying. However I've been told I'm too rude to everyone so, for _Maxx_'s benefit, I will point you gently in the right direction.
The problem is complicated by having the summary before the items, but there is an easy way to do this that does not require looping through the items twice. The follwoing psudo code should get you on your way:
summary is not set
for each item in the list
if the item key <> summary key
if the summary is set
update the grid entry for summary with the totals
create a new grid entry for summary with item key
set totals to zero
create a new grid entry for item
add item values to totals
if the summary is set
update the grid entry for summary with the totals
Panic, Chaos, Destruction.
My work here is done.

Thanks for your help. I'm now trying to write my program according to your psudo code. At first, I thought this program in a very confused way. Thanks a lot!

Is is it possible to develop a web page(Asp.Net) where from I will pass the UID/PWD and straight way enter the Outlook Web Access Page. I ment it will skip the Outlook Web Access login window.
Can someone help me with a solution.
Thanks in advance.

I'm not an expert on OWA... but it would stand to reason that, instead of using their login page, you could develop a sort of redirect page that automatically POSTs the username and password to whatever the default login page POSTs to. Again, I could be wrong, but that would make sense.

Well, i embedded this "axWindowsMediaPlayer1" player into my C# (Microsoft Visual), went to properties and added a link to my very small video.avi file online, i check it and it played perfectly! Then, i wanted a bigger video, i changed the url to a bigger video i uploaded (only 1:10), and it WONT PLAY! I click play, it says "connecting" "ready" and then i click it agian and it just says the same thing and plays nothing.
The first video is AVI and plays perfectly:
Video 1 (429.370 bytes)
The second video is AVI aswell and does NOT play:
Video 1 (6,000,172 bytes)
PLEASE HELP ME! Why wont the bigger file play? Why does it just not buffer!?
If this doesnt work, how do i simply just stream it from youtube? If i put a youtube browser in the client, it wont play and say i need flash! Please help ASAP!
Thankyou!

The problem you have, is to do with your bandwidth, not with the control.
Yes, a youtube video, needs an flv (flash) player in order to play.
