Question

How to change Working offline to working online

Asked by: KukiPei

Hi to all.

I'm working on some application with Visual C++.
I need to download file from ftp server.

I'm using this code:

"
CInternetSession mysession;
CFtpConnection* pFtpConn = mysession.GetFtpConnection("ftp server", "username", "password");
pFtpConn->GetFile("name of the file", "name of the file", FALSE))
"

Everything works fine when "Work offline" in Internet explorer is unchecked. (File->Work offline in IE).
but when  work offline is checked  it does't work.

Can I change work offline to work online from my application and how.

I hope you understand my quastion.
Thanks in advance.

Maybe this WinInet API function could be useful:

http://msdn.microsoft.com/library/en-us/wininet/wininet/internetcheckconnection.asp

Notice you have to include "wininet.h" and must link Wininet.lib
You can use it as:
InternetCheckConnection(NULL,FLAG_ICC_FORCE_CONNECTION,0);

 

by: jaime_olivaresPosted on 2004-11-20 at 13:20:43ID: 12635603

Also you can try with CInternetConnection::SetOption() function member with INTERNET_OPTION_IGNORE_OFFLINE flag.
It will work with IE5 - IE6 only

I tryed

InternetCheckConnection(NULL,FLAG_ICC_FORCE_CONNECTION,0);

but it doesn't work.

Also I tryed INTERNET_OPTION_IGNORE_OFFLINE

code:
CInternetSession mysession;
mysession.SetOption(INTERNET_OPTION_IGNORE_OFFLINE, 1);

but it gives me an error message:
error C2065: 'INTERNET_OPTION_IGNORE_OFFLINE' : undeclared identifier

I'm using Visual c++ 6.0
OS Windows 2000
IE 6

I included "wininet.h" and link Wininet.lib

 

by: jaime_olivaresPosted on 2004-11-20 at 13:57:52ID: 12635768

Use:
#define INTERNET_OPTION_IGNORE_OFFLINE 77

Good luck,
Jaime.

Now I don't have any error messages, but when I start application I get

Debug Assertion Failed!

dialog with abort , retry, ignore.

Maybe I'm using  CInternetSession::SetOption()  wrong.

code is the same:
CInternetSession mysession;
mysession.SetOption(INTERNET_OPTION_IGNORE_OFFLINE, 1);
 
Thanks for trying to help me.
