have you created a worker thread or UI thread using CWinthread

Actually i am not sur 
i create a dlg which has a control list. when this dlg is created by calling domodal(), a CWinThread is created in OnInit funtion. The thread will keep reading the log files and display the contents on the control list.
User will click cancel of the dlg to exit the dlg. problem is if i don't kill the Thread, it may still hold the handle to the log file. so further writing to the log file will cause problem.

There is several way to terminate your thread. Let me suppose that you understand about synchronisation.
And also to make thing more easier,
define a static member variable of type: static BOOL m_endLoop for your dialog class CYourDLG;
and also define a static member of type: static CEvent m_EventExit for your dialog class CYourDLG.
in the CYourDLG::OnInit() function initialize m_endLoop=0; and call m_EventExit.SetEvent().
And in your function OnCancel and OnOk at before to exit, call
WaitForSingleObject(EventExit,INFINITE); and in the first line in those 2 functions set
m_endLoop =TRUE;
and now in your loop function that terminate the thread, inside the loop insert this code:
if(CYourDLG::m_endLoop==TRUE)
{
// first to some cleaning and close all opened file or whatelse
...........
//and call
CYourDLG::m_EventExit.SetEvent();
return 0;
}
================== BUT when your start the thread insert this line at the begin of the thread function
CYourDLG::m_EventExit.ResetEvent();
That is.
You will have no access violation.
This solution must help.
Let me know if you have more questions

How can you not know? You call AfxBeginThread() in one of two ways. One way creates a worker (has no message pump) thread. The other creates a UI (has a message pump) thread.

Hello,
I think that you have a worker thread problem. Read here[^] about threads.
As stated in the article, you can kill your thread by calling ::TerminateThead((HANDLE)YourWinThreadObject);, but this is not safe, since your resources will not be cleaned up nicely...

is it normal that CEdit::SetSel(-1, -1); donnot erase my EditBox ?
from the MSDN, i read this :
void SetSel(
int nStartChar,
int nEndChar,
BOOL bNoScroll = FALSE
);
nStartChar
Specifies the starting position. If nStartChar is 0 and nEndChar is –1, all the
text in the edit control is selected. If nStartChar is –1, any current selection is removed.
i so thought that calling say m_peMyEdit->SetSel(-1, -1); (where m_peMyEdit is declaredas as a CEdit* and well initialized also) would clear the content of my Control.
should i feedback this to Microsoft ?

It does not clear the content of the control.
It removes the selection.
(e.g. if you press shift you can select chars in an edit control by pressing arrow keys) calling the setsel with -1 as startchar removes the selection... The text is still there completely, only any text that was 'selected', appears as normal now...
Hope this helps you,
Davy

Hi Tox,(Long time no see)
Why don't you use CEdit::SetWindowText("") for clearing the Edit Control

If not, Please help me with a complete code for developing a Windows Service
I need it very much and immediately

Yes, assuming you're running VS 2003.
- Shift+Ctrl+N to invoke New Project dialog box
- Expand Visual C++ Projects folder
- Select ATL folder
- Select the ATL Project type
- Specify name and location
- Click enter
- When the ATL Project Wizard displays, select the Application Settings tab
- Specify Server type of Service
- Click Finish
Voila! You now have a service with the guts of communicating with the SCM and a worker thread done for you.

Hi,
How to get the sectors/clusters of a particular file?
I am working on Windows 2000.
Hoping to get a reply soon.
TIA.
regards,
Jahfer V P.

Hi Jahfer,
I think you just need to reach to cluster, then following function would let you know how many sectors are there in one cluster & bye info of sector.
BOOL GetDiskFreeSpace(
LPCTSTR lpRootPathName, // pointer to root path
LPDWORD lpSectorsPerCluster, // pointer to sectors per cluster
LPDWORD lpBytesPerSector, // pointer to bytes per sector
LPDWORD lpNumberOfFreeClusters,
// pointer to number of free clusters
LPDWORD lpTotalNumberOfClusters
// pointer to total number of clusters
);
Then you need to iterate for sectors.

I need to get the sectors/clustors of a file.
A file may be in contiguous sectors or may be scattered, on the disk. I want to get this sector information.

I don't know it is fully possible or not with another API..
DeviceIOControl(). This API is used for similar type of work, even file related. Check MSDN for more detail.
I think it would be only help that I can do. Let me know if you get any direct method(by e-mail).
