No. It returns a DWORD, that is unsigned.
It wraps around after 49,7 days, though.
Win95 used to crash after that uptime. Not that it was generally able to stay up that long without crash anyway.
time64 returns the seconds since UTC. It wraps around somtimes in the year 3000
If you really need, you could mix in the milliseconds since startup (GetTickCount)
time64 relies on the computers clock being set - tampering with the clock *could* make your UID non-unique. That may or may not be a problem.
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

I am adapting for Visual C++ 2008 an old Borland C++ 4.5 program that contains many old-type string handling statements. The compiler tells me to "use _CRT_SECURE_NO_WARNINGS" to suppress warnings about strcpy and sprintf etc, but the online help gives no examples of its use. "#define _CRT_SECURE_NO_WARNINGS" has no effect. "_CRT_SECURE_NO_WARNINGS" (without quotes) alone on a line is treated as an undeclared variable. "#pragma _CRT_SECURE_NO_WARNINGS" causes a warning "unknown pragma". Please how do I put _CRT_SECURE_NO_WARNINGS in to suppress those warnings?

On my system (VS 2005), the following define (note: ends with DEPRECATE)
#define _CRT_SECURE_NO_DEPRECATE
works, while
#define _CRT_SECURE_NO_WARNINGS
not.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

I put this in Project Properties --> C/C++ --> Preprocessor definitions.

I got a "Database Timeout" error.
I m using an MFC application with MSDE database.
What can be the reason(s) for this??

I suspect there is a problem with your code. I could be wrong, though.

Hi all,
I am trying to work with video files larger than 6GB. The MFC file classes use DWORD's for position and length, which limits them to 4GB. I knwo there are equivalents for routines like CFileFind::GetLength or CFile::GetPosition, etc. but I can't seem to find them. Does anyone have an idea?
Thanks in advance.

U can use the API's directly.
GetFileSizeEx()<br />
SetFilePointerEx()

Not sure what version of VS you are using, but the file handing classes in the MFC (CFile etc) were updated to handle large file sizes. So the CFile::GetPosition() now returns a ULONGLONG, Seek() has a LONGLONG parameter...and so forth.
I now about the file limitation for VS6, but for the MFC 7.0 (VS7.1), these were updated.

you may use CreateFileMapping and ViewMapOfFile to map such files into your process address,__int64 will be ok.
DWORD dwFileLo = ::GetFileSize(hFile,dwFileHi);
ASSERT(dwFileLo != INVALID_FILE_SIZE);
__int64 qwFileSize = dwFileHi << 32 | (dwFileLo & 0XFFFFFFFF);
Later buggers harm more.

Dude! Information overflow!!
Condense your code sample and ask again, else I doubt anyone would consider wading through all of that.

I'm all curious now what his second question was.
I know the first was... "Here's 500 lines of my code, not even using the pre tag. What's wrong with it?".

How to programmatically make the dotted-line rectangle show on the focused button when a dialog based application is just launched? Thanks!
In VC++6, the dotted-line rectangle displays automatically for dialog based applications. But latter versions of Visual C++ do not unless user press the ALT key.

If you look up SystemParametersInfo and SPI_GETKEYBOARDCUES, they're the parameters that govern whether keyboard shortcuts show up.
But you're more interested in the focus rectangle on a dialog... I'm assuming that's related. But if not, just make sure you have a tab stop order set appropriately, and that your buttons have the WS_TABSTOP set. Beyond that, I have no idea...

Yes, tab order of the button is set, and WS_TABSTOP is set for the button (therefore when ATL is pressed the rectangle show up on that button).

And I added the below in MyDlg::OnInitDialog(), but I don't even see the menu-access key underlined... (unless ALT is pressed)
SystemParametersInfo(SPI_SETKEYBOADRCUES, TRUE, NULL, 0);
(Weird?! It does not allow copy and paste when editing this post? )

Doesn't it have to be...
BOOL bOn = TRUE;
SystemParametersInfo(SPI_SETKEYBOADRCUES, 0, &bOn, 0);
?
