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"

Converting string to CString

<br />
string stdStr = "Test";<br />
CString strText = stdStr.c_str();<br />

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 | :)

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

All IP-packets are sent with a CRC32 checksum that the receiver recalculates to validate the data. If the checksum is incorrect, the packet is discarded.
This happens regardless of what you do, it's how the IP-protocol works.

If you're using an UDP ports, the sender will never be informed whether the receiver got the packet or not, at any OSI level, since UDP traffic is connectionless.

If you're using TCP ports, the sender will be sent an ACK for each packet. Whether the packet is to be resent or not is depending on a configurable threshold in the registry found at HKEY_LOCAL_MACHINE/SYSTEM/currentcontrolset/services/tcpip/parameters.

This means that the sender cannot be informed if the receiver got a corrupt packet since the receiving application will never get the packet since it's been discarded.
I suggest you implement a small protocol of your own at the OSI application level that send ACKs to the sender's application. You will then be informed if the receiver never got the packet by the absence of an ACK.

Hope this helps
