Using FindFirstChangeNotification() problem

I am new to the win32 C++ language and is having a problem with inplementing 
the above structure, below is the code that i'm using to monitor a 
folder/file exclusively for renaming action:


//change notification is set now start monitoring
//start wait proccess
DWORD wp = WaitForSingleObject(ret, INFINITE);

   case WAIT_OBJECT_0 :
   HANDLE hDir = CreateFile(
    NULL, /* security descriptor */
    OPEN_EXISTING, /* how to create */
    FILE_FLAG_BACKUP_SEMANTICS, /* file attributes */

  DWORD BytesReturned;
     hDir, /* handle to directory */
     &Buffer, /* read results buffer */
     sizeof(Buffer), /* length of buffer */
     TRUE, /* monitoring option */
     FILE_NOTIFY_CHANGE_FILE_NAME, /* filter conditions */
     &BytesReturned, /* bytes returned */
     NULL, /* overlapped buffer */
     LPTSTR htxt;
     case FILE_ACTION_ADDED: htxt = "The file was added to the directory"; 
      case FILE_ACTION_REMOVED: htxt = "The file was removed from the 
directory"; break;
      case FILE_ACTION_MODIFIED: htxt = "The file was modified. This can be 
a change in the time stamp or attributes."; break;
      case FILE_ACTION_RENAMED_OLD_NAME: htxt = "The file was renamed and 
this is the old name."; break;
      case FILE_ACTION_RENAMED_NEW_NAME: htxt = "The file was renamed and 
this is the new name."; break;

     while (!Buffer[i].NextEntryOffset);

        if(FindNextChangeNotification(ret) == FALSE )


When i  run this code, it does nothing, what is meant to happen is for it to 
display a messagebox, stating what has taken place according to the "htxt" 

Anyone got any ideas?

Replying to Individual in Newsgroup using Outlook, with O.E. as NG reader
I'm using Outlook 2000 sp1 for E-mailing. It's set-up to use Outlook Express 6 as the newsgroup reader (whilst calling itself Outlook Newsreader). I recently wanted to reply to an individual in a thread. Everything seemed to go okay until I checked the 'Sent Items' of Outlook. There was an E-mail to the individual, but none of the text that I'd included was there, only the original newsgroup message. Does anybody know what's going on, how to fix it, or has anybody got any suggestions ? Thanks in Advance Duncan Anderson O/S = Win X/P home sp1 I think this happens be...

HTML spreadsheet problem
Hi, I have created a spreadsheet with Excel and have saved it to a HTML format to be browsed on the web. All works fine but the formatting has not been taken to the HTML version, and I have some fields that have capital letters in the HTML version that are small characters in the Excel format? Not really sure how this is possible? I have the same problem in reverse: internet pages opened in Excel are all fouled up. I think its due to the filters, the components that turn one sort of file into another. Sometimes, updating your filters will work. First, you might want to make sure that you...

Stationery Problem with ImageMaps OL2K / 2K2
Good Evening All, Thanks in advance for your responses. I'm developing a pretty simple stationery for a customer. Basically it's a three row table with images used as headers and footers. The footer image has 7 e-mail addresses on it and I setup a simple inline imagemap to facilitate hyperlinking. All good so far. Note that I developed the page in Notepad, and tested it using Outlook 2000 SR-1. I've sent the e-mail friends and colleagues who also use Outlook, Thunderbird, Eudora, Opera, and others.

What's the correct procedure to use a CBitmapButton in a dialog (to avoid resouce leaking)?
Hi, I have a CBitmapButton member in a dialog. The problem is that, after exiting my program, there is a cross button staying on my windows 2000's desktop now. The button is exactly the one I used in the dialog. Clicking on it doesn't do anyting. Rebooting the machine doesn't help. The application has been mailed to many customers. Now I expect they'll see this button on their machine but hardly guess that it's caused by my program. In DoDataExchange(), I associate the CBitmapButton member with a push button in the dialog's template. Then in OnInitDialog...

Problem with a date and concatenation
I got some data out of one of our in house databases and it comes out as 01/022206, for example..a missing second "/" (we need to FIX that damn databse too) I have thousands of these rows, and I need to do some analyses by date, so I need a correct date.

MX/DNS problem in Exchange
One of my users (on SBS 2003) has intermittent problems sending mail to a particular user elsewhere. After some research, I found out that the recipient's mail mail servers were moved from one domain hosting provider to a new domain provider, but they left their website (xxx) & domain hosting (.com) with the existing domain provider. So... the recipient's domain, correctly resolves to an IP address at the old provider, I can nslookup or ping, and it correctly resolves to the old IP address. However, the MX records (as tested externally via a websit...

Problem with CHKDSK
Hi When I run CHKDSK it gets a pass with /i but it hangs at the reboot with /f and /x and it says "CHKDSK is verifying indexes (Stage 2) 0 percent complete" and I have to reboot. I have a Seagate disk drive. I downloaded and ran Seatools for windows and got a pass on Long Drive Self Test. So I can assume that the disk is OK. The utility is read only it does not do any repair.

Prevent auto recoloring of chart when using Pivot Table data
I have crated a Pivot tabel with data I want to show in a Chart. My problem is when I refresh data the colours of the "data series" changes. For exaple I want one of my series "OK" always be shown in green colour, but after a refresh of pivot all colours changes. This problem is not only colouring. If I have made changes to my chart so that one series ar plotted on a secondary axis, and I change it to another chart type (e.g. the secondary should be shown as a line instead of column) this also changes when refreshing the data. Most irritating! Anyone that knows how to p...

SP3 Problem
Ever since I installed SP3 for Office XP, I have been getting the following error - "A program is trying to access email addresses you have stored in Outlook. Do you want to allow this?" I get this error only when I use Word as my email editor. Hence what is happening is that Outlook thinks that Word is a rogue program trying to send unauthorized emails. My question is, is there a way to prevent this - a whitelist of programs for example? Ajit Disable the PDFMaker addin. (See for details on how to do this.) "Aj...
