Yes, it is.  But it would be more logical if we wouldn't be able to power off the machine, which is already powered off.

AFAIK, VBox simply returns 0 (Success) if you try to power off a machine that is already powered off through the VBox Management API, which makes sense to me.

As found in some VB code:
Try
Catch ex As Exception
End Try
I may be posting a lot of these things here, as I finally got hold of the VB code that was for the previous system, that we're re-writing in C#.
It's bound to be full of gems like this.

You mean there was no code at all between Try and Catch, nor between Catch and End Try?
At least, he ought to have added an empty Finally then.

That is correct. I did not remove any code. It was a completely empty try-catch block.

Leaving the try...catch block empty was intentional. There exists a form with a textbox in which you can type code to be inserted in the try...catch block at runtime.

Today I came across the following code
if (1=1){
doSomeThing();
}
else{
doBestThing();
}
I am waiting for the execution of else part

well, it will compile for C and C++ at least!

Are you sure it will compile? '1' is not an l-value.

...the impossible takes slightly longer.

I wont, you can't assign to an rvalue.
UNLESS 1 is actually a macro that expands to something that makes sense on that context, but I don't even know if a macro can be called 1.

You cannot write a macro beginning with an digit.

I'm digging deep into the past, but I believe that with MS QuickC, it may have allowed the compile. Upon execution, memory offset 1 would be overwritten with 1. Possibly an immediate crash, or more likely, a crash waiting to happen.
I know it'd work with a cast to a pointer. QuickC was rather forgiving at times. Some of those times it was to my regret.

I happened upon an if yesterday that was deactivated with:
if ( <big>false &&</big> ...
Personally, I prefer to build with warnings as errors, but this codebase throws thousands of warnings.

Luckily the Mayans were wrong or perhaps doBestThing() would have executed a couple of years ago.

if (1=1){

Goto l;

else{
l: doBestThing();

Now the else part will run! Am I Correct?

I am not a goto expert(thank God) but i believe you have to define I before the Goto part.

Better saying

I knew that exceptions in the Load or Shown event of a Form get swallowed on 64bit systems (see e.g. https://connect.microsoft.com/VisualStudio/feedback/details/357311[^]). But this was not such an event.
The autosave procedure of our application receives its start signal from a System.Timers.Timer. The log file entries showed that the Timer_Elapsed handler was called. But strangely, not all of it... But nowhere an exception could be found in the log files, autosave simply did not work.
A newer version of a ThirdParty control fails at a property get when not run in the UI thread - that's where the execution of the Elapsed handler suddenly stopped.
But actually that's nothing new at all, you can read in the MSDN[^]Quote: In the .NET Framework version 2.0 and earlier, the Timer component catches and suppresses all exceptions thrown by event handlers for the Elapsed event. This behavior is subject to change in future releases of the .NET Framework.
Still true with .Net 4. Now I know that too.
