eg. check if the file exists before performing any operation on it (open, write, read) instead of just trying to open/write/read it and catching the exception.

It ain't that heavy, unless you have a debugger attached.

That sounds like a religious statement.

Do you think an integer representing an error would be easier?

Eddy Vluggen wrote:

Checking would be redundant in that case any way; but imagine some object that can have three different problems; would you use integers or exceptions to communicate the "error" to the user?

Don't shoot me for giving an honest reply.

And thus, no problem?

You're comparing integers and exceptions which is like comparing apples with pears.

2) Its ***highly*** doubtful you need all that data. What are you doing with it? Displaying it to a user? That's great... but whats a person going to do with 1.4M rows of data? Nothing... a human can't process that amount of data.

If someone plopped a report with 1.4M rows on it on your desk, what are you gonna do with it? I'd toss it in the recycle bin without even looking at it.

If he needs all that data to generate a usable report, thats another story.

In that case, he should probably do what another poster suggested and run the stats on the server instead of downloading all the data and doing it on the client.
