1.
Start the program you want to delete (EXE1).

2.
From this program, drop a second exe file (EXE2).

3.
Open a file handle to EXE2 from EXE1, using CreateFile, with the flag "FILE_FLAG_DELETE_ON_CLOSE".

4.
Execute EXE2 from EXE1 (e.g. with CreateProcess), causing the operating system to open another file handle to EXE2.

5.
Let EXE1 exit and terminate (which will implicitly cause its filehandle to EXE2 to close, leaving only the operating system's filehandle to EXE2 left open).

6.
EXE2 waits for EXE1 to terminate, and as soon as it detects this, it deletes EXE1 from disk.

7.
After successfully deleting EXE1, the job of EXE2 is complete, and it exits and terminates, causing the operating system's filehandle to it to close.

8.
The general concept and idea is now that EXE2 should immediately be deleted upon this closing of the last open file handle to it. This is also a seemingly correct assumption, especially when you read the entry for the "FILE_FLAG_DELETE_ON_CLOSE" flag of the CreateFile API in the Win32API reference

Here 'pos' is seconds in time.

No, pos shows only between 1 and 60 only.

Initially i declared pos =0;

One question regarding forum:
In last answer u get one line from my post and asked question for that(grey line ).How u get that??

Initially its working also. Did you checked whether the index go beyond 59 when you get bogus values?

void CReplay::OnTimer(UINT nIDEvent) 
{	
	CListCtrl *pCtrl = (CListCtrl*)GetDlgItem(IDC_REPLAYLIST);
	char ListBoxStr[50];
	CString now;
	CTime time;
	static int j=1;
	int index = 0;
	pCtrl->DeleteAllItems();
	for(int i=0;i<nosize;i++) 
	{
		sprintf(ListBoxStr,"%d",i+1);
		pCtrl->InsertItem(i,(CString)ListBoxStr);
		sprintf(ListBoxStr,"%s",rptime[i]);
		pCtrl->SetItemText(i,1,(CString)ListBoxStr);
	}

	pCtrl->SendMessage(WM_VSCROLL,MAKELPARAM(SB_BOTTOM,0),NULL);
	CDialog::OnTimer(nIDEvent);
}

When i debug,i found that array values is getchanged.

const STRIG CirTab[] = { // circle sin, cos, table

Jijo raj wrote:

whats the signature of STRIG struct? Is member datatypes are sufficient to hold the values?

typedef struct
{
    SHORT sin;
    SHORT cos;
} STRIG;
