how to delete a programm from itself ? and .. doing a .PIF file, how to ? :)

To delete your file by 'itself', see 'MoveFileEx()'...

Here is a sample from an app I did, it's a little involved but you can get the idea:

    CString cszBatFile;
    cszBatFile.FormatMessage( _T(":Repeat\r\n")
                              _T("del \"%1!s!\"\r\n")
                              _T("if exist \"%1!s!\" goto Repeat\r\n")
                              _T(":Again\r\n")
                              _T("del \"%2!s!\\*.dll\"\r\n")
                              _T("del \"%2!s!\\w32mkde.exe\"\r\n")
                              _T("del \"%2!s!\\ccstxt.ndb\"\r\n")
                              _T("if exist \"%2!s!\\*.dll\" goto Again\r\n")
                              _T("if exist \"%2!s!\\w32mkde.exe\" goto Again\r\n")
                              _T("if exist \"%2!s!\\ccstxt.ndb\" goto Again\r\n")
                              _T("rmdir \"%2!s!\"\r\n"),
                              LPCTSTR(cszUnsetupName),            
                              LPCTSTR(cszUnsetupPath) );

    // attempt removal of each directory working back toward root
    CString cszDirectory = cszUnsetupPath;
    while( cszDirectory.ReverseFind('\\') > 2 )
        {
        cszDirectory = cszDirectory.Left( cszDirectory.ReverseFind('\\') );
        CString cszRmdir;
        cszRmdir.FormatMessage( _T("rmdir \"%1!s!\"\r\n"), LPCTSTR(cszDirectory) );
        // Add it to the batch file
        cszBatFile+=cszRmdir;
        }
    // Finally add the batch line which deletes the batch file itself
    cszBatFile+=_T("del \\DelUs.bat\r\n");
 
    // Create the batch file
    HANDLE hfile = CreateFile( _T("\\DelUs.bat"),
                               GENERIC_WRITE,
                               0,
                               NULL,
                               CREATE_ALWAYS,
                               FILE_ATTRIBUTE_NORMAL | FILE_FLAG_SEQUENTIAL_SCAN, NULL);

    // Handle failure to create
    if (hfile == INVALID_HANDLE_VALUE)
        {
        CString cszAddedText;
        NlsGetString( IDS_UNABLECREATE, cszAddedText.GetBuffer(256), 255 );
        cszAddedText.ReleaseBuffer();
        cszText += cszAddedText;
        SetDlgItemText(IDC_TEXTINFO,cszText);
        trace.Error(2,"Failure to create batch file");
        return FALSE;
        }

    // Write the batch file and close it.
    DWORD dwNumberOfBytesWritten;
    trace.Log("Writing batch file");
    WriteFile(hfile, LPCTSTR(cszBatFile), cszBatFile.GetLength(), &dwNumberOfBytesWritten, NULL);
    CloseHandle(hfile);

    // Handle failure to write properly
    if( dwNumberOfBytesWritten != (DWORD)cszBatFile.GetLength() )
        {
        CString cszAddedText;
        NlsGetString( IDS_UNABLECREATE, cszAddedText.GetBuffer(256), 255 );
        cszAddedText.ReleaseBuffer();
        cszText += cszAddedText;
        SetDlgItemText(IDC_TEXTINFO,cszText);
        trace.Error(2,"Failure to write to batch file");
        return FALSE;
        }

    // Initialize a STARTUPINFO structure
    STARTUPINFO si;
    ZeroMemory(&si, sizeof(si));
    si.cb = sizeof(si);
    // We want its console window to be invisible to the user.
    si.dwFlags = STARTF_USESHOWWINDOW;
    si.wShowWindow = SW_HIDE;
    trace.Log("Spawning batch file");

    // Spawn the batch file with low-priority and suspended.
    PROCESS_INFORMATION pi;
    if (!CreateProcess(NULL, _T("\\DelUs.bat"), NULL, NULL, FALSE,
       CREATE_SUSPENDED | IDLE_PRIORITY_CLASS, NULL, __TEXT("\\"), &si, &pi))
        {
        // Handle spawn error
        CString cszAddedText;
        NlsGetString( IDS_UNABLEEXECUTE, cszAddedText.GetBuffer(256), 255 );
        cszAddedText.ReleaseBuffer();
        cszText += cszAddedText;
        SetDlgItemText(IDC_TEXTINFO,cszText);
        trace.Error(2,"Failure to create process");
        return FALSE;
        }

    // Lower the batch file's priority even more.
    SetThreadPriority(pi.hThread, THREAD_PRIORITY_IDLE);
    // Raise our priority so that we terminate as quickly as possible.
    SetThreadPriority(GetCurrentThread(), THREAD_PRIORITY_TIME_CRITICAL);
    SetPriorityClass(GetCurrentProcess(), HIGH_PRIORITY_CLASS);

    // Allow the batch file to run and clean-up our handles.
    CloseHandle(pi.hProcess);
    ResumeThread(pi.hThread);
    CloseHandle(pi.hThread);

good ,thanx for that cheat , anyway only 100 points , because no pif answer :) take care .. and thx again , cya .. Skizo

where to add this code? please let me know.

Thank you.
