DeviceIoControl function error

For starters, do not enable the OK or Apply buttons if either of the edit controls have invalid data. That alone will get rid of most, if not all, of your problems.

Hi All,

i am calling DeviceIoControl function to Reset the shared drive device

code snippet is as follows
DWORD dwErrCode, dwErrCode1;
HANDLE hDrive = ::CreateFile("\\\\.\\PHYSICALDRIVE0", GENERIC_READ |
GENERIC_WRITE, FILE_SHARE_READ |
FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING, 0,
NULL );

//check the error in getting teh handle
if (hDrive == INVALID_HANDLE_VALUE)
{
dwErrCode = GetLastError();
return 0;
}
DWORD dwBytesReturned = 0;
STORAGE_BUS_RESET_REQUEST sbRR;
sbRR.PathId = 0;

BOOL bRet = DeviceIoControl
(hDrive,
IOCTL_STORAGE_RESET_BUS,
&sbRR, sizeof(IOCTL_STORAGE_RESET_BUS),
NULL, 0, &dwBytesReturned, NULL);

if(bRet == 0)
dwErrCode1 = GetLastError();

CloseHandle(hDrive);

I am working on windows 2003 server, same code works fine on windows 2000

GetLastError gives "Incorrect Function Error"

can anyone help on this,

Thanks,
Tushar.

I think the fourth parameter to DeviceIOControl() should be sizeof(sbRR).

Could it be that the driver you are trying to reset does not support the specified function?

Hi,

Thanks for the reply,

But the same code works fine on windows 2000 machine for the same hardware.

But does the exact same driver run on both platforms? Chances are that it doesn't, and if that's the case, there could be a slight difference between the two. I'm just grasping at straws here, so my suggestions are somewhat limited.

Hi Programm3r,
Do you want to create the DSN at runtime? or can you create the DSN on a machine and then use it?

Somethings seem HARD to do, until we know how to do them.

David I have tried using that function but I get these error

error C2065: 'SQLConfigDataSource' : undeclared identifier
error C2065: 'ODBC_ADD_SYS_DSN' : undeclared identifier

I have included the following lib's:
- odbc32.lib
- odbccp32.lib

But nothing, what could be wrong?

Thanx

You need to #include odbcinst.h and odbccp32.lib

I just gave a thought on, can we change the language of the applications.
For ex:
Suppose Outlook and notepad are open. When we run an application and press a button on it the menu's etc change to the language that we specify.
like File,View,Edit are now being shown in English. As soon as we press the button in our application(to change the language) the menu changes(On Outlook and notepad changes to some other language like German etc......
I had two ideas to start with:
1) Develop a hook(WH_CBT or WH_SHELL)
2) System level programming. (That would be much more robust)
Does somebody here has the idea on how to achieve this ?

ok i understand but i am not so good and i need some help , i will explain to you again :

My aplication is CDialog i use 3 edit boxes and 1 CListCtrl .
First i wanted to search in CListCtrl from 1 edit box and the answer if exist in CListCtrl in another edit box.Now i want this :

0 1 2
---------------------------------------------------
| NAME | City | Country |
---------------------------------------------------
|George| London| England |
---------------------------------------------------
|George|NewYork| USA |
---------------------------------------------------
1) m_name CEdit
2) m_City CEdit
3) m_rezult CEdit
3) m_list CListCtrl

so far i done this :
void CMyList::OnOK()
{
UpdateData();
m_list.RedrawItems(0,m_list.GetItemCount());

CString sName = _T("Name");
m_name.GetWindowText(sName);

LVFINDINFO stInfo = {0};
stInfo.flags = LVFI_PARTIAL;
stInfo.psz = sName;
int nItem = m_list.FindItem( &stInfo );
if( nItem != -1 )
{
// the item is in the list control
CString sSecondColumnText = m_list.GetItemText( nItem, 1 );
// set the text to the second edit box
m_rezult.SetWindowText( sSecondColumnText );

//---------------------------------------------------------------------------------//

}
}

All i want is to search for this :

if i write in m_name and in m_city when i push the button i need the answer in m_rezult (the search rezult)

ex: if i write in m_name George and in m_city London i need the answer in m_rezult England ! and so on ! if i search for George and NewYork i need the answer in m_rezult : USA !!!!!

PLZ!!!! Make your choice and help me if you ...
