Is David Fenton right about error handling?

by: Anthony England | last post by:

I am considering general error handling routines and have written a sample function to look up an ID in a table. The function returns True if it can find the ID and create a recordset based on that ID, otherwise it returns false. **I am not looking for comments on the usefulness of this function - it is only to demonstrate error handling** There are three versions of this code.

Error handling

by: David | last post by:

How should sockets, filestreams, and anything else that needs to be closed be handled using try/catch/finally blocks? The only solution I can see is to make the objects public or use a public flag that the error handler can set so that the rest of the cold can clean up after the error handler has run (in my case when a hard close is performed my socket loses connection and throws an error- I need to close it after the error so it can...

Hello I'm a bit confused on how one should handle exceptions. I'm currently building an ADO.NET Windows Forms application. I've built a class for manipulating data within the database in question. This class is used from forms. Let's assume that there is an SQL error: this will throw an exception. Where should I handle it? How should I handle it? What to show when giving an error message?

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

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,...
