File Properties

Often we want to know the properties of a file like its full path, its date of creation, last access and last modification. Or we want to know whether the file is a hidden file, system file or read-only file. At such times, we simply right click on the filename (in Explorer or in any other software that can pop up a file dialog). From the context menu that appears we select the ‘Properties’ option and the OS shows all the file properties in a dialog box. We too can develop a program that can achieve this. Here is the code of this program.

#include "afxwin.h"

#include "afxdlgs.h"

#include "resource.h"

class myframe : public CFrameWnd

if ( d.DoModal( ) == IDOK )

filename = d.GetPathName( ) ;

CFile::GetStatus ( filename, fs ) ;

CTime cre, mod, acc ;

cre = fs.m_ctime ;

CString daystring ;

int day = cre.GetDayOfWeek( ) ;

creat.Format ( " Creation Day & Date :- %s %d : %d : %d Creation Time :- %d : %d : %d ", daystring, cre.GetDay( ),

cre.GetMonth( ), cre.GetYear( ), cre.GetHour( ), cre.GetMinute( ), cre.GetSecond( ) ) ;

On execution of the program a window appears with a menu attached to it. On selecting the menu item a file dialog is popped up. On selecting a file from this file dialog the properties of this file are shown in another dialog.

The file dialog is obtained by building a CFileDialog object and calling the member function DoModal( ) using it. Once the file is selected from this dialog its complete path is obtained using CFileDialog::GetPathName( ). This path name is passed to the GetStatus( ) static function of the CFile class. Along with the path a structure variable of the type CFileStatus is also passed. This structure is set up with the various file properties. These properties are then formatted properly and displayed in a dialog box. Note that the structure CFileStatus has been declared in the file ‘afx.h’.
