Mar 22, 2011My code block is below. As it turns out, rdrCurrentRate.GetString(12) is a null value, but the code block throws an error. "Data is Null. This method or property cannot be called on Null values."My intention is to write "if rdrCurrentRate.GetString(12) is NOT NULL, then sCurrentRateType = rdrCurrentRate.GetString(12)"
What am I missing here?
If Not String.IsNullOrEmpty(rdrCurrentRate.GetString(12)) Then
sCurrentRateType = rdrCurrentRate.GetString(12)

ExecuteNonQuery Not Throwing Error When Command Is Wrong
Oct 7, 2010I'm passing in a sql command such as "EXEC StoredProc 0" into a a function called ExecMyCommand where StoredProc is a stored procedure taking a parameter of 1 or 0.It works fine with the following code.I had tried to judge success by looking at NumRowsAffected but soon realized that the -1 could represent a successful run even if -1 was the return value.So then I changed the code and return mLastRunOutcome = False if there is an error.So for testing I changed the name of the SP to like StoredProc2 in the database and ran the same command "EXEC StoredProc 0" and to my amazement, no errors were thrown in the code below..Of course ran the same command in Query Analyzer and it barked that there was no SP by that name.How do I know when a command ran successfully or not in code here? and Why didn't the ExecuteNonQuery throw an error when the command was not right??[code]
View 2 RepliesStop A Program During Execution Any Other Way Than By Throwing An Error?
Aug 19, 2009Is there a command that will stop the execution of my program?
I have a service that is processes an exchange account via telnet every 10 minutes. During one point of execution the application could possibly have a response from the telnet session when there are NO e-mails in the folder, which would look something like this[code]...
So is it possible for me to just stop my application at that point since there's no point in continuing if there are no e-mails in the account?

Throwing Exceptions For User ? Or Better To Design Custom Error Message Framework?
Nov 10, 2010I never got into detailed error processing too much when I played in VBA/VB6 a lot. Mostly then, if you ran into a user error (such as some input of theirs failing a validation test of some kind), you popped a MsgBox() with some error information and the critical (or warning) icon, and safely aborted out of the code
In .NET, my reading basically points to exceptions as the end-all in error handling. It looks to me that if you know a spot of code where a user can screw up, you're supposed to catch it with either try...catch blocks (for things like data conversions), or standard if...the...else constructs for other things, and then throw a new exception if needed.
Isn't throwing an exception essentially a forced crash of a program in a sense (granted, you get the option of continuing)? Or are exceptions geared specifically for things like data conversion errors and other "things that shouldn't happen", and resume use of MsgBox() and friends for minor user screwups?
Consider the case of where you have a TextBox that is only supposed to accept numeric data (or heck, just a specific set of characters). Barring some other trick that lets you restrict that field (let's just assume it's freeform, programatically), it would seem a bit of a waste to throw new exceptions everytime they type in an invalid character, or even if the error checking doesn't happen until they press a submit button (like on a webpage). Popping a MsgBox() seems more sane in that case.
So what's the straight dope on exceptions and throwing new ones on user errors? How about if your program also exposes a programmatic framework? Bad usage of one of the programmatic functions definitely seems like new exception territory to me.
