it always return INVALID_SOCKET, and the error code is 10043.
but the IPv4 socket could be success everytimes.
how can i do? whether the IPv6 protocol was not deploy on my device? how to deploy it?

Pocket PC right? Does it even support IP6? I thought Windows Server 2003 was the first MS OS to support IP6.
[edit]
Googled IPPROTO_IPV6, IPPROTO_IPV6 Socket Options[^] came up, see the list of requirements.
Declared in Ws2def.h on Windows Server "Longhorn" and Windows Vista; include Winsock2.h.
Declared in Winsock2.h on Windows Server 2003 and Windows XP.

Windows Server "Longhorn" and Windows Vista support IPv6 by default, WindowsXp also support IPv6 by execute:"ipv6 install" in command line.
MS claim WinCE4.2 and higher versions support perfectly.
but i could not find how to configure it on the emb OS.
does the mobile OS have the same tools like "ipv6.exe netsh.exe ipconfig.exe" on x86?

show code snippet... have you checked what CoCreateInstance is returning! you can also use FormatMessage to get Human Readable message

either write your own sorting algorithm or use MAP<DATE,CString> way to get automatically sorted URL list based on Time.. also don't forget to switch off th default sorting of list ctrl!

Never go for this .... there is nothing there .
Only at the site you will see indexes & syllabus for the courses in interactive way
but while doing the course , I felt very cheated .
They charged Rs 6500 for "Programming Expertise in Visual C++ ". There was no time boundation , no
exercise checking , many lectures were absent and at the last they didn't give any project .
They were in hurry to give the certificate and get rid of me .
Same is the story with other online courses .
Never go for any e-course from KSET Pvt. Ltd. ( http://quest.ksetindia.com )

You need to convert LPCTSTR to BSTR and pass its address as parameter.
You can convert LPCTSTR to BSTR like this ;
BSTR bsVar = SysAllocString(lpCstr);
Do use SysFreeString() to release memory after use of BSTR.

thanks...but can you pls tell me more detail as change in my code...sorry but i am very much confused
|

As told earlier, Its compilation error. You need to use BSTR pointer.Use SysAlloString to convert LPCTSTR.
In case of CString object, you can use CString::AllocSysString for getting BSTR variable.

Hai Mr. Jadugar,
you can use Much Better class _bstr_t which is wrapper over BSTR and provide mechanism for LPCTSTR too!

Thank you.

You need to export your ScreenSaverProc function so scrnsave.lib can link to it...
See the "Creating a module-definition file" section in Handling Screen Savers[^]

Thank you Mark, I'm sure that is the problem. However, when I export the two functions, I get the following:
1>LINK : error LNK2001: unresolved external symbol ScreenSaverProc
So, again, I'm at a loss.
