I want to register a hotkey for my WinForm so that when I hold the,
say, Alt+M keys, it minimizes. How do I do that?

I found the easiest way is to create a menu item to do this and then link
the "hot key" to the menu item.

ACK. Note that the menu item doesn't necessarily need to be visible.

Thanks! That is a nice tip I will surely use in the future. For now,
I'll be using the Win32 API to register the hotkey that is system-wide
because this menu-item solution, I believe:
1. Will not be system-wide; and
2. Will not be able to restore the form once minimized.
But a great tip I never thought of, really. Thanks a lot.
Another related question:
I've seen examples that use RegisterHotKey API without a global atom
and some that do add a global atom for the key in the Global Atom
database. Would someone tell me whether it is absolutely necessary to
have a global atom for the hotkey? If not, what is the difference
between the two approaches.
Look at Francesco`s article regrding this http://www.dotnet2themax.com/ShowCon...0-c2bb7075ba78
the attom thingy well he tells it here :
"you need to install the hotkey, which you do by calling the RegisterHotKey
API function: this function takes a unique id, and MSDN docs explain that you
should call GlobalAddAtom to get such an id. Besides, you must store this id
in a form variable, because you need it later, to unregister the class and
delete the global atom you created"
so someone using the RegisterHotKey API function without the use of a
doesn`t follow the MSDN rule for getting the unique id or doesn`t care about
a good cleanup routine ( or isn`t aware that he should call GlobalAddAtom to
get such an id )

We have a SQL Server 7.0 database running with trunc. log on chkpt and

One of our DBAs insists that since the transaction log is being

because if a transaction comes through during the backup it will leave
the backup in an inconsistent state. I'm skeptical, but I don't know

Hi, all
I'm developing an application that needs to pop up when the user
presses a global hot key. I followed instruction using Win32 API
RegisterHotKey. It works fine at first, but what's the strange is after
I used Form.ShowInTaskBar = false to hide form, the hot key didn't work
any more. I remove the line, then it works again.
I try the code in CodeProject SystemHotkey too, but failed. I add
Form.ShowInTaskBar = false in its example...

I find the 'r/l-value reference' terminology rather confusing and I
find the following names for this new refrence type more suitable:
temporary reference:
Since it is generally intended to refere to temporary objects
Immidiate referenc:
Since literals are assumed as temporary in C++ and immidiate or quick
in assembly language.

Hi,
I am make a project to draw bitmap image. Pixel intensities are
calculated from data received from instruments. Problem is, sometimes
I get wrong data points, such as:
correct data should be in
wrong data might be 1000, or -50000
When I draw the bitmap, I would like to neglect these hot pixels
(extremely hot, because they are very far away from correct number).
And my gray-scale bitmap with start from ->.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.

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,...
