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". 
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?..

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

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.".

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.

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...

Hi,
I want to use a Active X contol in a win32 application.
How I can add that control to my project?
If you can Please explain me with a sample code.
Regards,

Active X components are basically COM components.
So you can create an instance of it and then use the control in your application.
I am a HUMAN. I have that keyword in my name........

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.

Check the locale of your PC from the Control Panel, Region and Language link.
I must get a clever new signature for 2011.

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) {
} else if (dynamic_cast<CMyTreeView *>(m_pWnd) != NULL) {
}
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()) {
} else if (m_pWnd->GetRuntimeClass() == CMyTreeView::GetThisClass()) {
}

error on GetThisClass()

That code was from a project made in Visual Studio 9.0 (2008).
The function may have a different name on your version of visual studio, or you may not be using the DECLARE_DYNAMIC or DECLARE_DYNCREATE.
If you are using 1 of the mentioned macros try checking the definition of them to see if the function has a different name. you are looking for a public static function that has the same return type as GetRuntimeClass(), probably CRuntimeClass*.
Otherwise you can just use the dynamic_cast method I described

Is that possible or all modules should be of the same architecture?
Dll is loaded with LoadLibrary and a function is called.

Well, up until a few days ago I thought it was impossible, but I noticed that occasionally x64 version of NTDLL was loading the x86 version of NTDLL into a x64 program.
I don't know how it is done, perhaps 1 of the many undocumented APIs.
In the past I have created a x86 helper .exe which loads the DLL, and returns whatever. This can be done with Remote Procedure Call, but I only ever used pipes.
EDIT: It may be loading them for resources rather than code with LoadLibraryEx, which should be allowed

Hi
i am beginner of win32 Vc++. I create Menu item and call File open dialog box. I have a File Menu. it contains Open, save and exit menu items.I have file open dialog box function. Open menu item id is: ID_FILE_OPEN.
my code like
case WM_COMMAND:
switch(wParam)
{
case IDOK:
EndDialog(hWndDlg, 0);
return TRUE;
case IDCANCEL:
EndDialog(hWndDlg, 0);
return TRUE;
case ID_FILE_OPEN:
OnFileOpen(hWnd, ID_FILE_NEW, 0, 0);
break;
}
But error is come like ID_FILE_OPEN' : undeclared identifier
how to fix this?
Regards,
M.Mathivanan

In your menu in the Resources window you will have specified a value for the menu item File>Open. You can find this value in the properties window (View->Other Windows->Properties Window) and click on the Open item in the file menu in the resource editor.
The value will also be #define'd in the Resource.h file, so be sure to #include "Resource.h"

When we press Shift+Delete key, a delete confirmation dialog is generated. I want to handle this dialog according my need or change its message. Can anyone tell me what thing is responsible for that dialog?
I either need to know the code which handles the delete confirmation dialog generated by the Shift+Delete key sequence in Windows XP, or the code by which we can control this operation.
