Hi all,
please explain me how can i get domain or workgroup details of any computer.
thanks in advance.

A little googling highlights NetGetJoinInformation[^], which will get you either domain or workgroup name - seems to work successfully for both workgroup and domain computers that I have access to.

Hi All,
Can any body please tell me,how to know whether a hard disk is S.M.A.R.T. supported or not.I tried using Win32_DiskDrive class using the index Interface Type.But it is not the value 10 which is SMART Notification even if the Hard disk is S.M.A.R.t. supported.

Try the Capabilities property, as documented here[^].

Sorry Dear,
I mentioned in my question that i tried Interface type by mistake.But i actually tried Capabilities property.Its only showing the properties 3 and 4 to be supported even if the disk is S.M.A.R.T. suppoprted.It should also show the property 10 which is S.M.A.R.T. notification.
Regards
Abinash

You can use something like this:
BOOL DriveSupportsSMARTCommands(DWORD dwDrive)
{
HANDLE hDrive;
TCHAR szDrive[MAX_PATH];
_stprintf(szDrive,_T("\\\\.\\PhysicalDrive%d"), dwDrive);
hDrive = CreateFile(szDrive,GENERIC_READ | GENERIC_WRITE,FILE_SHARE_DELETE | FILE_SHARE_READ | FILE_SHARE_WRITE,NULL, OPEN_EXISTING, 0, NULL);
if(INVALID_HANDLE_VALUE != hDrive)
{
GETVERSIONINPARAMS gvp = {0};
DWORD dwRet = 0;
if(DeviceIoControl(hDrive, SMART_GET_VERSION,NULL,0,&gvp, sizeof (GETVERSIONINPARAMS),&dwRet, NULL))
{
return (gvp.fCapabilities & CAP_SMART_CMD);
}
}
return FALSE;
}
SMART_GET_VERSION[^]
GETVERSIONINPARAMS[^]

Hi folks!
To get to the point, here's some code:
...
dc.BeginPath();
dc.Ellipse(rectangle);
dc.EndPath();
CBrush Brush(color);
CBrush *OriginalBrush = dc.SelectObject(&Brush);
dc.FillPath();
dc.SelectObject(OriginalBrush);
int PointCount = dc.GetPath(NULL, NULL, 0);
dc is valid, rectangle is OK, the ellipse gets filled as it should but when i call GetPath to retrieve the points in the path it returns -1 and i get "Cannot complete this function" from GetLastError(). Any ideas what might cause this? Thanks in advance.

Here's quoting from the documentation for FillPath:
MSDN wrote:
FillPath Function
Remarks
After its interior is filled, the path is discarded from the DC identified by the hdc parameter.

Thank you very much, i completely missed that, haven't worked with paths much yet.

I am using the following code snippet. This is the code which gets executed when I click on a Browse button.
Function call - BrowseDialog( GetParent()->GetSafeHwnd(), csTitle, lpszBuf );
Function Definition -
BrowseDialog(HWND hWndParent,CString pszPath,LPSTR csDialogTitle)
{
_tcsncpy(szInitialDir, pszPath, _MAX_PATH-1);
int nLen = _tcslen(szInitialDir);
if (szInitialDir[nLen-1] == '\\')
szInitialDir[nLen-1] = '\0';
BROWSEINFO bi;
memset((LPVOID)&bi, 0, sizeof(bi));
TCHAR szDisplayName[_MAX_PATH];
szDisplayName[0] = '\0';
bi.hwndOwner = hWndParent;
bi.pidlRoot = NULL;
bi.pszDisplayName = (LPSTR)szDisplayName;
bi.lpszTitle = csDialogTitle;
bi.lpfn = RecipeBrowseCallbackProc;
bi.ulFlags = BIF_RETURNONLYFSDIRS|BIF_EDITBOX|BIF_VALIDATE|BIF_USENEWUI|BIF_STATUSTEXT;
LPITEMIDLIST pIIL = ::SHBrowseForFolder(&bi);
BOOL bRet = ::SHGetPathFromIDList(pIIL, (char*)&szSelectedDir);
}
Some times I am getting crash when clicking on browse button and sometimes after opening the browse button and selecting another directory..
Can I know what is the fault in above code

Well, your code won't compile...
I can't see any definition for szInitialDir!
I can imagine it's a TCHAR array, MAX_PATH long... Make sure the last TCHAR is zero.
Beyond that, I'd have a look at the crash, and see that the debugger tells me. Also go line by line, and check the contents of bi. You also have a callback function - it is the right signature? If not, you could be getting stack corruption.
Does it work without the callback?
Go to boring and simple, get that working, then build up.

This is my call back function..
int CALLBACK RecipeBrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData)
{
BOOL bReturn;
UNREFERENCED_PARAMETER(lpData);
switch (uMsg)
{
case BFFM_VALIDATEFAILED:
// AfxMessageBox(GetString(107), MB_OK | MB_ICONEXCLAMATION);
bReturn = TRUE;
break;
case BFFM_INITIALIZED:
::SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)szInitialDir);
bReturn = FALSE;
break;
case BFFM_SELCHANGED:
{
TCHAR szDir[MAX_PATH];
//don't allow the CSIDL_NETHOOD typically C:\Documents and Settings\username\NetHood
//as it contains folder shortcuts...
if (SHGetPathFromIDList((LPITEMIDLIST) lParam ,szDir))
{
LPITEMIDLIST pidl = NULL;
SHGetSpecialFolderLocation(NULL, CSIDL_NETHOOD, &pidl);
TCHAR szNethoodDir[_MAX_PATH];
BOOL bRet = ::SHGetPathFromIDList(pidl, (char*)&szNethoodDir);
LPTSTR lpsz = _tcsrchr(szDir, (_TUCHAR) '\\');
int nIndex = lpsz - szDir;
szDir[nIndex] = '\0';
if (_tcsicmp(szDir, szNethoodDir) == 0)
::SendMessage(hwnd,BFFM_ENABLEOK,0 ,0);
::SendMessage(hwnd,BFFM_SETSTATUSTEXT,0,(LPARAM)szDir);
}
bReturn = FALSE;
}
break;
}
return bReturn;
}

I'd have a good look at CPallini's suggestion - you are doing very strange things there.
But that would only crash when you leave the browse function, not while in it. I'd put a breakpoint in your RecipeBrowseCallbackProc, and check each line - especially the BFFM_SELCHANGED case, as you know it crashes in there...
Good luck,
Iain.

As has already been suggested, start with the basics and build upon them (e.g., remove the callback function, change ulFlags). Don't try and debug a problem with so many "unknowns."

Try This.
LPMALLOC pMalloc;
LPITEMIDLIST pidl;
TCHAR szPath [MAX_PATH];
BROWSEINFO bi = { GetSafeHwnd(), NULL, szPath,NULL,
BIF_VALIDATE|BIF_UAHINT|BIF_USENEWUI|BIF_RETURNONLYFSDIRS, NULL, NULL };
pidl = SHBrowseForFolder ( &bi );
if ( NULL != pidl )
{
if ( SHGetPathFromIDList ( pidl, szPath ) )
{
}
SHGetMalloc ( &pMalloc );
pMalloc->Free(pidl);
pMalloc->Release();
}

Please use 'code block' button for code snippets.
At first look your function call doesn't match well with function prototype.

This line looks very suspiscious: how is szSelectedDir defined?

Hello,
I have a created a map named mapList
std::map<string, std::vector<FileInfo*>> mapList;
and loading to key and value.
when i try to create a view of the file in the process address space (MapViewOfFile) which returns a pointer to the file view.
error C2440: '=' : cannot convert from 'std::map<_Kty,_Ty> *' to 'LPCTSTR' msg is thrown
I think there is an error in typecasting from 'std::map<_Kty,_Ty> *' to 'LPCTSTR' as i'm implementing in below manner.
pBuf = (std::map<string, FileInfo*> *)MapViewOfFile(hMapSharedMemory, FILE_MAP_ALL_ACCESS, 0, 0, 0);
Can anyone suggest me a solution.
Thanks in advance,
Regards,
Mayur M

Wow, your code seems to be wrong on so many points 
First thing, why are you trying to assign a pointer to a map into a LPCTSTR pointer (I guess that pBuf is LPCTSTR by lookking at your error). That doesn't make any sense to me.
Second, you can't put a full map this way in the shared memory. You will need to serialize in some way your array: write the number of elements and then write all the elements one by one in the shared memory. You will need to apply the same principle when you deserialize: read the number of elements, then the elements one by one and add them to a local map object.

There are so many things wrong with attempting what you are that it's difficult to know where to start...
However, the main point is that std::map, std::string and std::vector all rely on pointers to external data. You do not have control over those pointers, so you cannot guarantee that they will lie within the mapped area of memory (unless you use specialised allocators, as documented here[^]).

Your immediate problem here is a symptom of a bigger one. Tell us more about what you're trying to do and maybe we can suggest a solution to the bigger problem.

Thanks for the reply.
sry for not providing proper information.
I'm facing a new problem of coping the contents from map to a map pointer.
pBuf = (std::map<string, FileInfo*> *)MapViewOfFile(hMapSharedMemory, FILE_MAP_ALL_ACCESS, 0, 0, 0);
std::map<string, FileInfo*> mapList;
I have to insert the mapList to pBuf.
Does insert or get_allocator resolve my problem.

As I said before...that's just not going to work. What problem are you trying to solve with this?
If you want to share/communicate a map between two or more processes using shared memory, look at Boost.Interprocess[^] - that has containers designed to be used in a shared memory area.
If you're just sending the map from one process to another, I'd serialize it - Boost.Serialization[^] is an option there.
