Most probably asked allready hundred time...
VS gives a lot of warnings and hints. Hints like 'put this and that in curly brackets or not', what else.
Why the hell VS can't give me a hint for really important things like 'pay attention you are using a class IDisposable' keep in mind to use it in a using block?
[Edit]
Ok, ok: But maybe then at least if I hover over the class name in VS, at least show me explicitely that it is IDisposable

Probably because most of the time IDisposable objects are persisted for some time: for example, the Winforms Control class implements IDisposable, and Form is derived from that. You don't want a "Oi!" every time you add a form to your project, or a control to your form!

I agree on that. So the next question: Is it really impossible for the compiler to give me a hint when IDisposable is not used in a using block or not disposed explicitely? Most probably very hard, but not sure wheter it is impossible.
[Edit]
I think I found the answer by myself 
if (random) obj.Dispose();

The compiler can't - it can't keep track of objects that are created at run time and passed into / out of methods.
A simple example: create a disposable class in a method, return it as an object, and the compiler can't trace it any further as an IDisposable instance.
It would probably be possible to work it out within a method if the instance never leaves it, but that's non-trivial as well as the instance could be added to an array or other collection which could be part of a class instance which is returned by the method.
There are a lot of ways for the compiler to get it wrong and be more annoying than mixing tabs and spaces in Python ...

I didn't think this (annoyance) was possible.

OTH: GC is able to detect not longer in use objects. Why not the same for IDisp?
|
|
|
|
|
Because it's not important.
Frequently I wrap an IDisposable object in another class and dispose of it when I dispose of the wrapper object, no big deal. I wouldn't want to have a warning I would have to disable to avoid an error when I compile with warnings as errors.
There are bigger bugs to fry.

But in case you use a class from a library: You really always check wheter it is IDisposable or not?
In my case it was ManagementObjectSearcher from System.Management.
To check you need to go back inhertitance until you end in Object or yes maybe before in IDisposable

Ah, well, I rarely use third-party rubbish anyway. Or VS.
Put it in a using and see if it compiles.
Or use Intellisense to see if it has a Dispose.
|
|
|
|
|
Intellisense, yes that would be nice. No idea where Intellisense shows it is IDisp.
Btw. third-party rubbish like ManagementObjectSearcher

P.S. Also consider classes which are IDisposable but which have private constructors, such as Singletons and classes which provide a static Create method.
Sadly, many bloggers pass along misinformation about IDisposable and the using statement.

How did you do the upgrade? I used AOMEI Backupper, which includes a specific "upgrade to SSD" option and it worked quickly and didn't give any problems. Apparently partition boundaries need to be aligned differently, so a straight "clone" may not work perfectly.
★ SSD Alignment - SSDs have different structures to HDDs so the partitions will need to be aligned along the SSD block boundaries during the cloning process. With this option, AOMEI Backupper will take over the job, as thus you don't need to worry about the alignment of the SSD and the speed of the cloned SSD.
Don't know how your disk is organised, but it's worth a try (and free).

I used Apricorn's SATA Wire and EZ Gig run from the CD drive. Basically, plug up the new drive to a USB, start the software on the CD, do the clone, shutdown, and swap the drives....easy peasy! 
I've use it a couple of times previously with no problems whatsoever. I'm betting mostly on an ID10.T error here for the missing files/'differences'. For the speakers though it's entirely possible I pulled a speaker wire so hopefully that's an easy fix.

For me, Family Tech Support is another source of income $$$. I don't help anyone under the age of 65 for free. Millennials are double the price.

I'm one of those boomers. I'm also the family IT guy.
I don't get complaints.

I've had to look it up, but yes, he is a 'boomer' and apparently, I'm an 'X'. He thinks I'm doing it for free because I enjoy playing with computers all day! In reality, I'm doing it to possibly put an end to the constant whining about how slow his laptop is.

I do immediate family only, and am explicit that my work doesn't come with a warranty, speedy service guarantee, etc. If they want that; the blue box or local computer shop will both sell it for a few hundred dollars. 
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, weighing all things in the balance of reason?
Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful?

I don't talk to my family. Except for SWMBO. She just surfs the net using my wi-fi. So as long as it is working (And I use it myself, so I notice it first,), I am golden.

90% of family tech support is now managed by my wife, I enter the scene only when SHTF or a network must be set up (she's perfectly capable of connecting any device to a running network).
She is way more patient than me in help desk. And for stuff on smartphones I too end up asking her  she uses hers much more than I use mine.

That's why I don't tell my family that I work with computers. I've told them that I am a drugdealing pimp, and they seem to have believed that...
