open the file using CFile

Not a good idea as Open() is an expensive call, not to mention that it could easily fail if another process has the file open.

my code:

BEGIN_EVENTSINK_MAP(CBrowserPage, CDialog)
//{{AFX_EVENTSINK_MAP(CBrowserPage)
ON_EVENT(CBrowserPage, IDC_EXPLORER1, 271 , NavigateError, VTS_DISPATCH VTS_PVARIANT VTS_PVARIANT VTS_PVARIANT VTS_PVARIANT VTS_PVARIANT VTS_PBOOL)
ON_EVENT(CBrowserPage, IDC_EXPLORER1, 252 /* NavigateComplete2 */, OnNavigateComplete2Explorer1, VTS_DISPATCH VTS_PVARIANT)
//}}AFX_EVENTSINK_MAP
END_EVENTSINK_MAP()

OnNavigateComplete2Explorer1 can work,
NavigateError can't work,why?
my ie is 6.0
thanks!

CString is a MFC (or ATL) class. if you don't have a MFC project, you won't see it.

did you create a console project ?

U need MFC support for the application.
CString is defined at "Afx.h"

if add support to for MFC, u can simply use the basic mfc classes.

These are the main include files.

#include <afxwin.h> // MFC core and standard components
#include <afxext.h> // MFC extensions

in a normal MFC application, this will be included at "StdAfx.h"

go to your project settings, add MFC support in it.

then, in your files, #include (before all other includes) the file "stdafx.h" which should have been created in your project.

there is a simple method I can suggest.

Create a new console.

at the Application settings, "Support MFC"

copy the code or add teh file u have implemented to this newly created workspace. it will work fine.

that is the better way

the include files are AfxWin.h and afxext.h

thanks for reply, what i want is when you press the open button from file menu, it will prompt a open dialog box, right. Basically that box can open the files from c or d drives, but now i want that open dialog box display the ftp server files, not the files from the drives.

hope you can get my mean. thx.;)

have a nice day Smile | :)

Re: Get filename from Ftp!

You can still use CFileDialog or GetOpenFileName(). It will just require a starting folder. Check out the OPENFILENAME.lpstrInitialDir member variable.
