getting System time

How do you get the current time of the machine in milliseconds.

I have used the time() function from time.h before but that only gives me back up to the seconds..

Any ideas would be great - thank you

I do not know of a time function that returns the milliseconds. If, however, you are looking for a stopwatch function, you may give CWnd::SetTimer / CWnd::KillTimer a look. However, be forwarned that even though it boasts triggering off of microseconds, it does not guarantee accuracy... quote from MSDN

"Because the accuracy of a timer depends on the system clock rate and how often the application retrieves messages from the message queue, the time-out value is only approximate."

I apologize if this suggestion isn't even remotely close to what your looking for.

Monitor registry

Hi
I have this program which reads/write some things from/to registry, but i have no idea what it exactly reads/writes in the registry when it gets launched.

Is there any utility to monitor what a program exactly does when it gets launched, registry is only one of the things that can be monitored.

Anyone knows?

Greetings
Jens

If you want an excellent freeware installer I highly recommend Innosetup from:-

To all the answers......

I think he ment was "how to develop a windows installer for my application?" not how to download one...

well, you need to create a wizard (read the msdn for that), then each page will collect the necessary information for installation, then you can zip it all up to 1 file (a setup.exe) and there you have it......

try to look in code project for such an example.....

Hope i helped ya

A CToolBar. Nevermind, I was pretty sure I had seen a CToolBar in my add-in code, but I was wrong.

Disabling the toolbar does not seem easy. Actually, the toolbar seems to be directly handled by Visual C++, and it will enable one or more button, depending on how maning commands you bind using the AddCommand, SettAddInInfo and AddCommandBar methods. i have no clue as whether it is only possible to disable the bar. Sorry to be a PITA on this question Frown | :(

Changing cursor

Hi everybody !

I would like to change the mouse cursor when an event happen. I used SetCursor but cursor is reseted when I move the mouse. I took a look at the doc and they say the class cursor for the window must be NULL !!

How can I acheive that ? I need also to have the cursor set to default when the event is finished!

Thanks

If you want the hourglass cursor displayed during lenghty operations:

CWaitCursor wait;
DoSomethingThatTakesTime();

Thanks but it's not the hourglass cursor. In fact I click on a button on the toolbar (the zoom button) and my cursor changes into a zoom. When the user has selected the item to zoom, the cursor came back to an arrow.

The docs are right. You need to set the cursor for the window class to NULL. You also need to handle
the WM_SETCURSOR message too. This message is called by the OS when the mouse is moved.

If you want to immediately change the cursor, you use SetCursor as you have already seen.

So its a combination of all three things.

Iain.

char __iainclass [] = "IainView";

BOOL CIainView::PreCreateWindow( CREATESTRUCT& cs )
{
	WNDCLASS	wc;
	wc.style	= CS_DBLCLKS | CS_OWNDC | CS_HREDRAW | CS_VREDRAW;
	wc.lpfnWndProc	= ::DefWindowProc;
	wc.cbClsExtra	= 0;
	wc.cbWndExtra	= 0;
	wc.hInstance	= cs.hInstance;
	wc.hIcon	= 0;
	wc.hCursor	= 0;
	wc.hbrBackground= NULL;
	wc.lpszMenuName	= NULL;
	wc.lpszClassName= __iainclass;

	AfxRegisterClass (&wc);

	cs.lpszClass = __iainclass;

	return	TRUE;
}

That's for MFC. To set wc.hCursor=NULL is even easier in SDK, as you have to explicitly create a class
in the first place.
