T-sql Catch Error Message
have a doubt about Try Catch blocks. If I get an error in Try block then it will redirect to Catch block as per to the rule. So can I set visible = true to my label into catch block. i.e lblError.visible=true; Is it correct as per coding standards?

This way we can keep track of errors and exceptions. –Nikhil Agrawal May 17 '12 at 14:03 add a comment| up vote 0 down vote Catch block gives developer to recover the damage done by th

being able to handle errors helps to ensure that an unexpected event will not go on to wreck the system you are working on. Take the example below. http://www.vexasoft.com/blogs/powershell/7255220-powershell-tutorial-try-catch-finally-and-error-handling-in-powershell Every week in our sample company (MyCompany.Com) Human Resources are going to upload a list telling us who should have access to the Expenses database. If a name isn’t in the list from HR we’re going to remove it from the group and that user will no longer be able to log expense claims: $AuthorizedUsers= Get-Content \\ FileServer\HRShare\UserList.txt $CurrentUsers=Get-ADGroupMember "Expenses Claimants" Foreach($User in $CurrentUsers) { If($AuthorizedUsers error message -notcontains $User) { Remove-ADGroupMember -Identity "Expenses Claimants" -User $User } } Now, you can see where this is going to go wrong. One week HR doesn’t get around to uploading the list or, just as we are about to access the list, the file server dies. Suddenly PowerShell throws an error on the Get-Content cmdlet and the $AuthorizedUser variable remains empty. Because our script doesn’t handle catch error message errors, it continues to run and, in a very short space of time, it has removed every user from our expenses group. Pretty soon the irate phone calls start flooding in and life gets a little less happy. The way to avoid all this is to catch the errors and then handle the event that caused them (which in this case is halt the script and have a shout at someone in HR). Terminating and Non-Terminating Errors One of the key things to know when catching errors is that only certain errors can be caught by default. Errors come in two types – terminating and non-terminating. A terminating error is an error that will halt a function or operation. If you make a syntax error or run out of memory, that is a terminating error. Terminating errors can be caught and handled. Non-terminating errors allow Powershell to continue and usually come from cmdlets or other managed situations. Under normal circumstances they cannot be caught by Try-Catch-Finally. The Get-Content error in the example above is a non-terminating error. Treating Non-Terminating Errors as Terminating So how do you catch a Non-Terminating error? Basically, you tell PowerShell to treat
