Hello guys!

I have to connect to WebDAV Server, example: http://webdav.pspace.co.kr
But I cannot find any code example for DavAddConnection Function.

And, in MSDN I found this:
"Use this function when you are connecting to a WebDAV server using the Secure Sockets Layer (SSL) protocol and therefore must specify a certificate. To connect to a WebDAV server without specifying a certificate, use a Windows networking function such as WNetAddConnection2 or WNetAddConnection3."

Does anyone know some examples of DavAddConnection?

Found some code examples for WNetAddConnection2 and tried to connect, but, unsuccessfully.

CString passW=_T("pwd123");
CString userN=_T("user1");
CString locname=_T("webdav.pspace.co.kr");
DWORD dwRetVal;

NETRESOURCE nr;
DWORD dwFlags;
memset(&nr, 0, sizeof (NETRESOURCE));
	
nr.dwType = RESOURCETYPE_ANY;
nr.lpLocalName = (LPTSTR)((LPCTSTR)locname);
nr.lpRemoteName = (LPTSTR)((LPCTSTR)locname);
nr.lpProvider = NULL;
dwFlags = CONNECT_UPDATE_PROFILE;
dwRetVal = WNetAddConnection2(&nr, passW, userN, FALSE);

if (dwRetVal == NO_ERROR)
    AfxMessageBox(_T("Connection added to"));
else
    AfxMessageBox(_T("Error"));

I'm getting "Error".
By the way, I'm I doing right trying to connect to WebDAV server via this technic?

Thank you.

Use this to see what error you are getting. That may shed some light on what may be causing it

if (dwRetVal == NO_ERROR)
	AfxMessageBox(_T("Connection added to"));
else {
	TCHAR szError[32];
	_stprintf(szError, _T("Error %u"), dwRetVal);
	AfxMessageBox(szError);
}

Thanks for the reply.
I'm getting "Error 487".

MSDN[^] says

Error Name: ERROR_INVALID_ADDRESS
Error Code: 487 (0x1E7)
Error Text: Attempt to access invalid address.

Check out your last parameter in WNetAddConnection2(&nr, passW, userN, FALSE);
According to MSDN[^] 0 is not a legal value for the parameter dwFlags and FALSE is #define FALSE 0.

Did you mean to pass in your variable dwFlags? (in the sample on MSDN they do)

Hello.
I have tried a couple of thing to make the code work. But, still, I cannot connect to our WebDAV server "webdav.pspace.co.kr". Confused | :confused:

But, using the code shown below, I'm getting a positive answer: "Connection added to":

CString locname=_T("\\\\www.barracudaserver.com\\dav\\");
DWORD dwRetVal;
NETRESOURCE nr;
DWORD dwFlags;
memset(&nr, 0, sizeof (NETRESOURCE));

nr.dwScope=RESOURCE_GLOBALNET; 
nr.dwType = RESOURCETYPE_ANY;
nr.lpLocalName = NULL;
nr.lpRemoteName = (LPTSTR)((LPCTSTR)locname);
nr.lpProvider = _T("");

dwFlags = CONNECT_UPDATE_PROFILE;
dwRetVal = WNetAddConnection2(&nr, _T(""), _T(""), dwFlags);

if (dwRetVal == NO_ERROR)
        {
             AfxMessageBox(_T("Connection added to"));
	}
else    
        {
             TCHAR szError[32];	
             _stprintf(szError, _T("Error %u"), dwRetVal);
             AfxMessageBox(szError);
        }

In the case of locname=_T("\\\\webdav.pspace.co.kr\\") the result is "Error 53:", which means "The network path you specified is not found."

May be something is wrong with the server or may be I'm using the wrong approach.
Any ideas?.. Unsure | :~

Running your code with locname=_T("\\\\webdav.pspace.co.kr\\") and running a packet sniffer I get the response

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>401 Authorization Required</title>
</head><body>
<h1>Authorization Required</h1>
<p>This server could not verify that you

browser doesn't understand how to supply
the credentials required.</p>
<hr>
<address>Apache Server at webdav.pspace.co.kr Port 80</address>
</body></html>

I'm sure you can figure out what the problem is from the response Big Grin | :-D

Dear Andrew!
Thanks for your help!

I'm sorry for being pesky and dumb.
I can connect to the server using browser with username and password.
But, I'm not being able to do it using my app.

Still I get the same error: "The network path you specified is not found.".

Sniff | :^)

I have never used WNetAddConnection2, and what I have been telling you is from reading MSDN and running your code on my computer so i dont know of any reasons that this might be hapening. Since i dont have an account on webdav.pspace.co.kr[^] the best i can offer is that you run Wireshark[^] and start the sniffer while you try to connect to the server to see what the server is sending back to you.

How to use ActiveX control in win32?

Hi,
you might want to check out this part
nr.lpLocalName = (LPTSTR)((LPCTSTR)locname);
based on MSDN: http://msdn.microsoft.com/en-us/library/aa385413(v=vs.85).aspx[^]

lpLocalName should be NULL in you case
"A pointer to a null-terminated string that specifies the name of a local device to redirect, such as "F:" or "LPT1". The string is treated in a case-insensitive manner."

but you use webdav.pspace.co.kr, which may cause the problem I think...

How I can add that control to my project?
If you can Please explain me with a sample code.

Active X components are basically COM components.
So you can create an instance of it and then use the control in your application.

That's a but simplistic. An ActiveX control is a COM object but writing code to correctly host it is far from trivial: in fact it's hard. The easiest way is to use MFC's or ATL's hosting code.

I tried it but I am getting "US" as my system time zone and Ip is of india.
On what basis it is giving "US" and how can I get correct country name?

Hi all,

i have split my application in one row and two column ,for first column im using CTreeView derived class and for second column i m using CFormView derived class.

in second column i m replace diffrent-2 formview according to need.

its working fine.but at certain point i need to chk which formview is currently visible in second column.

please tell me what function and api use for this.

thanks in advance.

If you have RTTI enabled (which it is by default) you can use dynamic_cast to check.

dynamic_cast will check the type information and only succeed if it is a valid operation, otherwise return NULL, so to see if a variable is of a type:

if (dynamic_cast<CMyFormView *>(m_pWnd) != NULL) {
	//its a CMyFormView
} else if (dynamic_cast<CMyTreeView *>(m_pWnd) != NULL) {
	//its a CMyTreeView
}

alternativley, if you are using DECLARE_DYNAMIC or DECLARE_DYNCREATE in your class definitions (should be using DECLARE_DYNCREATE to use it in a spitter if i remember correctly) then you can also check the type information with

if (m_pWnd->GetRuntimeClass() == CMyFormView::GetThisClass()) {
	//its a CMyFormView
} else if (m_pWnd->GetRuntimeClass() == CMyTreeView::GetThisClass()) {
	//its a CMyTreeView
}
