using and error trapping

I've just started using the 'using' keyword for database connections
etc. Is it not possible to use try catch blocks with using? And if so,
how do you trap errors when using using?

It is possible to do so.

If you want to continue with using, try this:

try
{
using (SomeObject obj = new SomeObject())
{
... something that can go wrong here
}
}
catch (YourExceptionC lassHere ex)
{
}

Or you can nest the try/catch block inside the using block.

Hi,

in exactly the same way:
try{
using() {}
}catch{}

or
using(){
try{
}catch{}
}

In the first case the connection will be closed (and out of context)
in the catch block

In the second the connection might still be open and in context so you
can access it

I need to be able to trap errors at the application level. I added this code to the Global.asax file. The code I wrote is supposed to get the last error that was generated and write to the event log as well as fire up my email class and generate an email to send me the error. But no matter what I do, I still get the icky looking yellow and white error screens. I’ve turned on customErrors in the web.config but not default URL setting....

I support an MS Access application in which errors are trapped using the On Error statement. Just recently, the users of this system have experienced run-time error number 3021 on a random basis.

It has always been my understanding that these error numbers would not be used by Microsoft and were available...

Hi there, I am having difficulty with a piece of code which would work wonders for my application if only the error trapping worked properly. Basically, it works as follows: - adds records from rsSource into rsDest - if it finds a key violation then it deletes the current record from rsDest and adds the new record from rsSource. This works perfectly - but only for the first found duplicate record, it brings up the error

Hi Gurus Does anyone know how I set the error trapping to option 2 in visual basic. I know that you can go to tools, options and then choose on unhandled errors only, but is there a VB command that I can use instead? Cheers Nicolaas

I have a subform which is causing a 3314 (Field can't contain a null value because required is set to True) error. I solved this problem by trapping it in the before update event. But then I started getting a "No Current Record" error. I wanted to see what err number was coming through, so I put a MsgBox in the subform's error event. But the MsgBox never came up and the error is now gone. Is the MsgBox pulling the focus away from the...

This all takes place within one form, in which the Word.Application and Word.Document objects are both private form-level variables. Just to be on the safe side I included this piece of code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
