copied!<p>I have a Windows Mobile 6.5 application where I'm trying to monitor a file for changes. If I run the code below, then open WordPad and edit and save "\MyDir\Foo.txt", I only get notifications about temporary files being changed. </p> <p>For reference, I'm using Windows Mobile 6.5 Professional CE OS 5.2.23090.5.3.0. And, I have the same issue with Windows Mobile 6.1 Professional CE OS 5.2.21051.1.6.4.</p> <pre><code>#include <vector> int _tmain( int argc, _TCHAR* argv[] ) { HANDLE change = ::FindFirstChangeNotification( argv[ 1 ], FALSE, FILE_NOTIFY_CHANGE_CEGETINFO | FILE_NOTIFY_CHANGE_LAST_WRITE | FILE_NOTIFY_CHANGE_LAST_ACCESS | FILE_NOTIFY_CHANGE_CREATION | FILE_NOTIFY_CHANGE_ATTRIBUTES | FILE_NOTIFY_CHANGE_SIZE ); if( INVALID_HANDLE_VALUE != change ) { while( WAIT_OBJECT_0 == ::WaitForSingleObject( change, INFINITE ) ) { NKDbgPrintfW( L"Change detected\n" ); DWORD returned = 0; DWORD available = 0; if( ::CeGetFileNotificationInfo( change, 0, NULL, 0, &returned, &available ) ) { std::vector< BYTE > buffer( available ); if( ::CeGetFileNotificationInfo( change, 0, &buffer.front(), buffer.size(), &returned, &available ) ) { BYTE* current = &buffer.front(); const FILE_NOTIFY_INFORMATION* info = reinterpret_cast< const FILE_NOTIFY_INFORMATION* >( current ); for( current; NULL != current && info->NextEntryOffset > 0; current += info->NextEntryOffset ) { info = reinterpret_cast< const FILE_NOTIFY_INFORMATION* >( current ); NKDbgPrintfW( L"\t%s: %#08x\n", info->FileName, info->Action ); } } } ::FindNextChangeNotification( change ); } ::FindCloseChangeNotification( change ); } return 0; } </code></pre> <p>The output in the example I give above is:</p> <pre><code>Change detected 667F.tmp: 0x00000003 667F.tmp: 0x00000003 667F.tmp: 0x00000003 667F.tmp: 0x00010000 </code></pre> <p>Where I would expect it to be:</p> <pre><code>Change detected Foo.txt: 0x00000003 Foo.txt: 0x00000003 Foo.txt: 0x00000003 Foo.txt: 0x00010000 </code></pre> <p>What do I need to change to get the functionality I'm looking for?</p> <p>Thanks, PaulH</p>
