第一种:(普通批处理方式)

procedure DeleteMe;
var
Batchfile: TextFile;
BatchFileName: string;
ProcessInfo: TProcessInformation;
StartUpInfo: TStartupInfo;
begin
BatchFileName := ExtractFilePath(ParamStr(0)) + '_deleteme.bat';
AssignFile(BatchFile, BatchFileName);
Rewrite(BatchFile);

Writeln(BatchFile, ':try');
Writeln(BatchFile, 'del "' + ParamStr(0) + '"');
Writeln(BatchFile,
'if exist "' + ParamStr(0) + '"' + ' goto try');
Writeln(BatchFile, 'del %0');
CloseFile(BatchFile);

FillChar(StartUpInfo, SizeOf(StartUpInfo), $00);
StartUpInfo.dwFlags := STARTF_USESHOWWINDOW;
StartUpInfo.wShowWindow := SW_HIDE;
if CreateProcess(nil, PChar(BatchFileName), nil, nil,
False, IDLE_PRIORITY_CLASS, nil, nil, StartUpInfo,
ProcessInfo) then
begin
CloseHandle(ProcessInfo.hThread);
CloseHandle(ProcessInfo.hProcess);
end;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
DeleteMe;
close;
end;

end.
