Thanks Roger,
So, you agree with the two issues I pointed out?

Reference member variable binded to local variable or binded to "deleted" variable is not an issue?

No i mean is it is not a issue of a reference variable.
Consider instead of reference you have a pointer.
It will still be a dangling pointer right??
What i want to say is its a common problem. It does not arise because you use reference variable.
Don't you agree??
Yes with reference you feel it is issue because you cant reinitialize the reference.
And if if the object is going to be deleted in between then there is no use of using it as a reference. instead you can use pointer so you can reinitialize to NULL or some other valid object.
Regards,
Sandip.

how to display text to edit boxes like printf in c while the program is running.
if i have some code in c like
{
printf("hello");
//do some computations for some time and then
printf("%d",result);
}
thanks & regards

you have to call SetWindowText() on your edit box instance.
but maybe you should start learning MFC/Win32 because that's a really very simple task.
|
|
|
|
|
you can use SetWindowText to set the text in the edit box. if you want all of the text to appear, as it does in the console window you can set the multiline property and the want return property to true.
Somethings seem HARD to do, until we know how to do them.

Use sprintf() (documentation here) to copy the formatted data into a string then use SetWindowText() (documentation here) to put this text into the edit control.

And what is your problem about?
You may (Win32 ):
(1) format a string using sprintf
(2) send the string to the edit box using SetWindowText .
On the other hand, using MFC you may:
(1) map a CString variable to the CEdit control.
(2) use the CString::Format method to properly format such variable.
(3) call CDialog::UpdateData(FALSE) of your dialog.

Hai!
I am creating an XYZ.txt file in my project,
i want that each time the XYZ.txt is created the name must be not simple as XYZ.txt, but it must be XYZ_DATE_TIME.txt
XYZ_27-08-2008_02-12.txt
XYZ_27-08-2008_16-45.txt

See SYSTEMTIME and GetSystemTime/GetLocalTime to get the time information for a system.
Later you can format the string to your needs using CString::Format()

You can use functions _strdate_s and _strtime_s for getting time and date as string...
Quickly typed in a function which does this...
CString CreateFileNameWithTimeStamp( LPCTSTR lpctszTitle, LPCTSTR lpctszExtension )
{
CString csFileNameWithTimeStamp = lpctszTitle;
const int BuffSize = 50;
TCHAR szBuff[BuffSize] = { 0 };
_strdate_s( szBuff, BuffSize );
csFileNameWithTimeStamp += "_";
csFileNameWithTimeStamp += szBuff;
_strtime_s( szBuff, BuffSize );
csFileNameWithTimeStamp += "_";
csFileNameWithTimeStamp += szBuff;
csFileNameWithTimeStamp += lpctszExtension;
csFileNameWithTimeStamp.Replace( _T( '/' ), _T( '_' ));
csFileNameWithTimeStamp.Replace( _T( ':' ), _T( '_' ));
return csFileNameWithTimeStamp;
}
How to call?
CString csFileName = CreateFileNameWithTimeStamp( _T( "ABC" ), _T( ".txt " ));
Output looks like...
ABC_08_27_08_14_27_34.txt

You could use COleDateTime::Format() to generate the time stamp. For instance,
COleDateTime DateTime = COleDateTime::GetCurrentTime();
CString TimeStamp = DateTime.Format( _T("%d-%m-%Y_%H-%M"));
CString FileName;
FileName.Format( _T("XYZ_%s.txt"), TimeStamp );

There is a class A which is defined like
#include "stdafx.h"
class A
{
public:
A();
~A();
};
static A a;
A::A()
{
int * i = new int[10];
}
A::~A()
{
}
int _tmain(int argc, _TCHAR* argv[])
{
return 0;
}
Is there a memory leak here; The only diff is here we create the object of the class A as static.
