This is code from that link.
TCHAR strPath[ MAX_PATH ];
SHGetSpecialFolderPath(
0,
strPath,
CSIDL_DESKTOPDIRECTORY,
FALSE );
In the above code you have to replace bold parameter with the one you are interested in.
In your case CSIDL_APPDATA /CSIDL_COMMON_APPDATA what ever you need..
Regards,
Sandip.

Hi, may be not a good question. I have structure and I have created pointer to a structure. It is giving me memory leak if I delete this pointer also. Please help me how can I delete this pointer. Find below the code.
<br />
struct DemoTreeData<br />
{<br />
DWORD m_obj_id;<br />
RWCString* ptext;<br />
};<br />
<br />
DemoTreeData* pTreeData=new DemoTreeData;<br />
pTreeData->m_obj_id = debug->GetData();<br />
pTreeData->ptext = new RWCString(debug->GetMessage());<br />
delete pTreeData;<br />
pTreeData=NULL;<br />
Can I delete the pointer like above or we have to write the destructor for that? Please suggest me.thanks..

Two solutions: either write a destructor and inside the destructor, take care of destroying pText if not NULL (you'll also have to write a constructor to initialize it to NULL) or don't forget to destroy pText externally if you allocated it. Solution 1 is better.

this is creating memory leak, you have to first delete memeory allocated to ptext, then delete the main structure.
Since, when you allocate memory to structure object, it will allocate only 4 byte to ptext object since it is pointer and when you delete the structure pointer it will only delete the 4 byte, which it is allocated to the variable at the time of allocation not the memory you allocate to ptext variable.
Now, for saving your self from memory leak, it would advisable first to delete memory allocated to datamember then delete the structure object itself

try UpdateWindow() api, it will post WM_PAINT message to Listctrl to redraw it self!

As your running the CListCtrl in a CFormView you are probably DDX'ing the control to assign it to a member variable. In your header you will have somwthing like:
CListCtrl m_myList;
In the .cpp file:
DDX_Control(pDX, IDC_LIST1, m_myList);
To cause the window to re-draw itself you will need to call the UpdateWindow function as follows:
m_myList.UpdateWindow();
If you vote me down, my score will only get lower

There is no easy place that I can think of where you can catch the WM_VSCROLL event of the CListCtrl.
I would suspect the problem lies in the NM_CUSTUMDRAW handler for the items being drawn.
If I remember correctly a CLIstCtrl uses the ScrollWindow function and then gets you to draw the new items which have scrolled into view. The ScrollWindow function only scrolls the areas for which a column has been created for. Options:
1. Change your custon draw function to limit the background colour drawing to the width of the created columns so you do not draw in the unused blank area.
2. Try changing the style of the CListCtrl to included the LVS_EX_FULLROWSELECT style.
m_list.SetExtendedStyle(m_list.GetExtendedStyle() | LVS_EX_FULLROWSELECT);
This may cause the control to scroll the entire client area correctly.
If you vote me down, my score will only get lower

Hi all,
At one point of my application(using vc++) I need to restart the system. That I am doing like-
BOOL CtestShutDlg::RestartSystem()
{
HANDLE hToken;
TOKEN_PRIVILEGES tkp;
// Get a token for this process.
if (!OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &hToken))
return( FALSE );
// Get the LUID for the shutdown privilege.
LookupPrivilegeValue(NULL, SE_SHUTDOWN_NAME, &tkp.Privileges[0].Luid);
tkp.PrivilegeCount = 1; // one privilege to set
tkp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
// Get the shutdown privilege for this process.
AdjustTokenPrivileges(hToken, FALSE, &tkp, 0, (PTOKEN_PRIVILEGES)NULL, 0);
if (GetLastError() != ERROR_SUCCESS)
return FALSE;
// Shut down the system and force all applications to close.
if (!ExitWindowsEx(EWX_REBOOT,
SHTDN_REASON_MAJOR_OPERATINGSYSTEM |
SHTDN_REASON_MINOR_UPGRADE |
SHTDN_REASON_FLAG_PLANNED))
return FALSE;
return TRUE;
}
It restart the system immediately when this function called up. I want that there should be some kind of warning or any type of message to user "your system need to be reboot now" like that before rebooting.
Please suggest me some way how can I do this.
Thanks

Place a MessageBox before Rebooting, based on user selection, you can implement rebooting logic like :-
if(MessageBox("Do You want restart the computer","",MB_YESNO)== IDYES))
else

You can use WMI.

WMI C++ Example[^]
And here is WMI class that you may be looking for with all the hdd information
Win32_PhysicalMedia[^]
