I like the enterprise library model. You decide whether to catch the exception or rethrow based on configuration.

I will catch exceptions if there is something I can or should do in response to that exception. Sometimes I'll just catch an exception, log the exception details somewhere, and then throw it back up the call stack so that other call sites can do what they need to do with it.

Enjoy the weekend,

Most simple exceptions like validating input and the like I do on the spot. Most complicated situation what I run into in libraries, I'll usually let bubble to the using application, so they can be logged. Those types of exceptions I like to have a full stack trace for tracking the application break.

I guess for me, it all depends on whether or not it's an exception I'll want to investigate and need all the information I can get. Most exceptions in an API library I let bubble.

True - It is just unusual for me to be initiating a thread in this forum.

Weird - It looks like the forum messed up - This was a reply to Josh's post.

Yup, I agree with that - Users not being the most loquacious when it comes to describing the details of what went wrong it can be very useful.

Thanks for your response.

Yeah me too, I usually find what I'm looking for in articles or google. Most of what I can't find there, I assume nobody has attempted. And I assumed that was a response to Josh.

But it's lots of fun surfing for questions I can answer, helps stroke my ego. Poke tongue | ;-P

What is your policy on catching exceptions and why?

You should catch them as soon as you can deal with them but no sooner.

So I Wouldn't write:

<br />
catch(Exception e){}<br />
or <br />
catch(OrSomeFileNotFoundException e){} //Unless you can deal with it, don't catch it.<br />

Makes sense to me.

The value property on HtmlInputFile is not settable

23-Jun-06 8:19

If you use the method above, and pass it node '13', it will process '131' and '132' before doing 13. You're not using the treeView.Nodes are you?

What ever owns the 1, 11, 12, 13 & 14 nodes (treeView or another node) won't have 131 and 132 in it's Nodes collection, node 13 will. A TreeNode object has a Nodes colleciton just as TreeView does. That's why the method above accepts a TreeNode, and pocesses it's children before itself.

Maybe I don't fully understand you question.

Hello,

I am using standard OpenFileDialog window. Is there a way to suppress (disable) the New Folder button, so that the user does not have the ability to create new folders?

Thank you.

I don't see a 'New Folder' button in the OpenFileDialog, so i can't help you there. But if you are using the FolderBrowserDialog, set the ShowNewFolderButton property to false.

When MS release .Net 3.0 and C# 3.0, will these be compatible with VS 2005, does anyone know? I've only just stumped up the cash for VS, and I'm looking forwards to having to stump up even more!

Cheers,

1.1 was not compatible with VS.NET, 2.0 is not compatible with 2003, I don't think 3.0 will be compatible with 2005 Frown | :-(

It currently is compatible with VS2005. Keep in mind that .NET 3.0 is just a marketing term. It really uses .NET 2.0 - but has tons of extra classes added in.
