Why are you reading the file twice?

Does Anyone know how to compare two dates, and if one date is greater than other date can we find out number of days between them.

Is there any function or class that can do it automatically.

Pleas help me
Thanks in Advance

Assuming you're using the COleDateTime in MFC you can subtract the 2 dates, which will return a COleDateTimeSpan object. Then you can use the GetDays function to see how many days the 2 dates span.

Like this:

COleDateTime date1(2006, 8, 28, 0, 0, 0);<br />
COleDateTime date2(2006, 8, 30, 0, 0, 0);<br />
<br />
COleDateTimeSpan span = date2 - date1;<br />
int numDays = span.GetDays();  // should return 3<br />

signcode is part of the SDK and must be in your path for this to work. If using Visual Studio .NET 2003, run 'Visual Studio .NET 2003 Command Prompt' from Start, All Programs, Microsoft Visual Studio .NET 2003, Visual Studio .NET Tools.

If using VS 2005, the signcode tool has been replaced with the signtool program. Use Visual Studio 2005 Command Prompt to run this.

signtool is also part of the standalone Platform SDK.

The default filter of that Browse dialog is EXE, DLL and OCX files. Select 'Cabinet Files (*.cab)' from the 'Files of type' drop-down to pick your cab file.

Alternatively use signtool sign to specify the options on the command line.

operator new

Waldermort30-Aug-06 20:59

30-Aug-06 20:59

I was wondering if there was a way to extend already allocated memory similar to what realloc() does. I know the operator new can be initialized with existing memory, but I have yet to find a way to make that memory grow.

char *tmp = new char [10];
strcpy(tmp,"hello");
char *tmp2 = new(tmp) char [20];
strcpy(tmp2,"Another string");
delete [] tmp;

This of course throws an exception because it's writing past the end of the array. Is there a way to do this without allocating, copying then deleting?

basically, if you use C++ (and you do, as new operator is not a C operator), prefer C++ classes instead of the C-runtime. STL is a powerful library which is too much abandonned because of the fear of templates...

I totally agree with you. I am just the sort of person who can't settle for "If it works it works", I need to know how it works. When I understand exactly what the code is doing behind the scenes, I have feel I have more control over what I can do.

Thanks for that, I suppose overloading them is the only way to go, but I can't understand why an operator for this wasn't created along with new and delete.

nope. new serves for allocating a new object, not reallocating an already existing one...
