4. Probleme mit Verzeichnis überwachen

Probleme mit Verzeichnis überwachen

  • _

    Hey @all,

    ich habe hier folgendes Programm

    #define WIN32_LEAN_AND_MEAN
#define _WIN32_WINNT 0x501
#include <windows.h>
#include <stdio.h>
#include <winbase.h>
void WatchDir()
{
	for(;;) {
	BOOL bResult;
	HANDLE hDir;
	BYTE Buf[10000];
	DWORD RetBytes;
	FILE_NOTIFY_INFORMATION *pInfo;
	DWORD i = 0;
	WCHAR FileName[1000];

	hDir = CreateFile(
		L"C:\\OracleTest\\oracle\\flash_recovery_area\\WWGDCF\\BACKUPSET",
		FILE_LIST_DIRECTORY,
		FILE_SHARE_READ | FILE_SHARE_WRITE | FILE_SHARE_DELETE,
		NULL,
		OPEN_EXISTING,
		FILE_FLAG_BACKUP_SEMANTICS,
		NULL);

	bResult = ReadDirectoryChangesW(
		hDir,
		Buf,
		10000,
		TRUE,
			FILE_NOTIFY_CHANGE_FILE_NAME		// Löschen, Erstellen oder Umbenennen
										| FILE_NOTIFY_CHANGE_DIR_NAME		// Löschen oder Erstellen oder Umbenennen eines Verzeichnisses
										| FILE_NOTIFY_CHANGE_SIZE			// Größe ändert sich
										| FILE_NOTIFY_CHANGE_LAST_WRITE 	// Dateizeit Letzte Änderung
										| FILE_NOTIFY_CHANGE_ATTRIBUTES	// Attribute geändert
										| FILE_NOTIFY_CHANGE_LAST_ACCESS 	// Dateizeit Letzter Zugriff (auch Lesen)
										| FILE_NOTIFY_CHANGE_CREATION 	// Dateizeit Erstellungsdatum ändert sich
										| FILE_NOTIFY_CHANGE_SECURITY,
		&RetBytes,
		NULL,
		NULL);

	for(;;) {
		pInfo = (FILE_NOTIFY_INFORMATION *)&Buf[i];
		switch(pInfo->Action) {
		case FILE_ACTION_ADDED: wprintf(L"file added: "); break;
		case FILE_ACTION_REMOVED: wprintf(L"file deleted: "); break;
		case FILE_ACTION_MODIFIED: wprintf(L"time stamp or attribute changed: "); break; 
		case FILE_ACTION_RENAMED_OLD_NAME: wprintf(L"file name changed - old name: "); break;
		case FILE_ACTION_RENAMED_NEW_NAME: wprintf(L"file name changed - new name: "); break;
		default: wprintf(L"unknown event: ");
		}

		lstrcpyn(FileName, pInfo->FileName, pInfo->FileNameLength / sizeof(WCHAR) + 1);
		FileName[pInfo->FileNameLength / sizeof(WCHAR) + 1] = '\0';
		wprintf(L"%s\n", FileName);

		if(pInfo->NextEntryOffset == 0) break;
		i += pInfo->NextEntryOffset;
	};

	CloseHandle(hDir);
}
}

int main() {
	WatchDir();
	return 0;
}

    Mein Problem ist nun das ich nicht alleEvents abfange...
    Beispiel: Ich füge 15 Dateien hinzu (je 10 KB) von 01.dat bis 15.dat
    dann bekomme ich 15 file added Nachrichten.
    Beim löschen der 15 Dateien bekomme ich jedoch nur ca. 5 - 13 Meldungen... Woran liegt das?

    Hier mal die Ausgabe:

    Rufe CreateFile () nur einmal vor Eintritt in die äussere for-Schleife auf. Ebenso CloseHandle () nur einmal erst nach Verlassen der äusseren for-Schleife.
