Question:
I want to kill a task.
How?

Answer:
It's little bit API's programming. Please take care the code. You might kill another task possibly important.

Here the code, tried at 95/98/ME/2000/XP.


uses
Tlhelp32;

function KillTask(ExeFileName: string): Integer;
const
PROCESS_TERMINATE = $0001;
var
ContinueLoop: BOOL;
FSnapshotHandle: THandle;
FProcessEntry32: TProcessEntry32;
begin
Result := 0;
FSnapshotHandle := CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);
FProcessEntry32.dwSize := SizeOf(FProcessEntry32);
ContinueLoop := Process32First(FSnapshotHandle, FProcessEntry32);
while Integer(ContinueLoop) <> 0 do
begin
if ((UpperCase(ExtractFileName(FProcessEntry32.szExeFile)) =
UpperCase(ExeFileName)) or (UpperCase(FProcessEntry32.szExeFile) =
UpperCase(ExeFileName))) then
Result := Integer(TerminateProcess(
OpenProcess(PROCESS_TERMINATE,
BOOL(0),
FProcessEntry32.th32ProcessID),
0));
ContinueLoop := Process32Next(FSnapshotHandle, FProcessEntry32);
end;
CloseHandle(FSnapshotHandle);
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
KillTask('notepad.exe');
end;
{ For Windows NT/2000/XP }

procedure KillProcess(hWindowHandle: HWND);
var
hprocessID: INTEGER;
processHandle: THandle;
DWResult: DWORD;
begin
SendMessageTimeout(hWindowHandle, WM_CLOSE, 0, 0,
SMTO_ABORTIFHUNG or SMTO_NORMAL, 5000, DWResult);
if isWindow(hWindowHandle) then
begin
{ Get the process identifier for the window}
GetWindowThreadProcessID(hWindowHandle, @hprocessID);
if hprocessID <> 0 then
begin
{ Get the process handle }
processHandle := OpenProcess(PROCESS_TERMINATE or PROCESS_QUERY_INFORMATION,
False, hprocessID);
if processHandle <> 0 then
begin
{ Terminate the process }
TerminateProcess(processHandle, 0);
CloseHandle(ProcessHandle);
end;
end;
end;
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
KillProcess(FindWindow('notepad',nil));
end;

    you can quickly reproduce the repair sql database file process with another utility for data recovery
