Reposting the same question the next day without answering the questions that were asked on your previous attempt will just get you ignored.

Hi, Does anyone know whether there is a TryCatch-Snippet wich can built try{}catch{}-blocks with all possible Exceptions thrown by a Methode ?
or
Is there a way to create such a snippet ?
|
|
|
|
|
I don't know if such snippets exist but I know that you can create your own snippets
|
|
|
|
|
There isn't one. How would it be possible for the snippet manager to know all Exceptions possible from a method, especially if the method made calls other methods in an external assembly?

try
{
}
catch(Exception error)
{
}
will catch all exceptions. However, this is not a recommended practice since it will also catch unrecoverable or systems exceptions (e.g. System.OutOfMemoryException, SecurityException, ThreadAbortException, etc.)
The best practice is to catch only the exceptions you can recover from. Otherwise, don't handle them.

Well, not all, only .NET exceptions. To catch all exceptions, you have to specify a parameterless catch:
try {
} catch {
}

Right, it will catch all .NET exceptions.
An empty catch will catch non-exception objects -- CLI languages are urged, but not required to, throw only System.Exception objects. However, I wouldn't call those exceptions anymore; those are thrown objects, not thrown exceptions, right?

I would call an exception an exception, regardless of what object is thrown to handle it. The exception is the situation, not the object.

Ah, see, when I was talking about exceptions, I was talking about System.Exception-based classes. Anyways, I suppose it's not such a big deal.
*edit* after looking into this a bit, I see the framework also refers to non-System.Exception objects which are thrown as "exceptions" in the documentation - interesting! So, you were right.
Another interesting side note is the System.Runtime.CompilerServices.RuntimeCompatibilityAttribute which tells the CLR to wrap all non-System.Exception "exceptions" in a real exception class before throwing it.

I read somewhere that this has changed in .NET 2.0 and you don't need empty catch blocks anymore.

There is a System.Runtime.CompilerServices.RuntimeCompatibilityAttribute for assemblies that tells the runtime whether to wrap all "exceptions" that do not derive from System.Exception with a System.Runtime.CompilerServices.RuntimeWrappedException. Maybe that's what you're thinking of?

Hi,
I'm struggling with a problem. I want to catch a 'WM_COPYDATA' event that occurs in a C# application.
I send a data from a C++ application. The bridge is correctly done I think.
So, sometimes it works, usually when my C# application is active.
But most of the time, it doesn't work, because when trying to catch the appropriate WM_COPYDATA message in WndProc overrided method of my C# application, the program stays catching a couple of other messages like: WM_WINDOWPOSCHANGED, WM_ACTIVATEAPP, WM_NCACTIVATE, WM_ACTIVATE and so on.
Doing so, it almost never catch the WM_COPYDATA message that I sent from my C++ application.
Can you help me please ?
Thanks.
P.S.: I catch messages in my C# application like this:
protected override void WndProc(ref Message m)
{
string g = m.ToString();
if (m.Msg == WM_COPYDATA)
{
// instructions.
}
}

You really need to add:
else
{
base.DefWndProc(ref m);
}
So that other windows messages get handled properly. I don't know if this will fix your issue or not. I am not sure if your C# app will receive the message if it is not active.

I already had:
base.WndProc(ref m);
Isn't it supposed to do the same thing ?
I tried what u asked me, but my c# application doesn't receive any information back.
thx.

It is the same thing, I guess you didn't post that code in your previous post.
Ben

Yes, I didn't post it.
I also tried to use PostMessage instead of SendMessage. But I don't get appropriate results.
Any idea ?
Thx.
