 Coolness: 47555 | Anyone know how to display the last modified date of an html document in another html document?
I'm using the following script: But this only return the lastMod. date of the current document. Any suggestions? |

 Coolness: 147010 | document apparently refers to the current document... you need to open the other one and access it with a 'document2' variable, and the same snippet should work. |

| Coolness: 47555 | do you mean save the address of the other document as a string in the variable document2? |

| Coolness: 147010 | saving it as a string is a way, but i think there are smarter means to access it, such as with a direct reference (ie kinda like a pointer), or maybe a 'HtmlDocument' or 'Document' object (if something like that exists).
i never really used javascript so i don't know what exactly you should use |

 Coolness: 340350 | opening another file with javascript to do that is a bad way of doing it.. you're better off ditching the javascript way and doing it with php.. |

 Coolness: 92950 | She's not using a database though, that's the thing.
You can look into a windows API called ReadDirectoryChangesW. It has a few parameters containing file info from a directory you will specify(as the HANDLE), and then use the FILE_NOTIFY_CHANGE_LAST_WRITE command. See below. I know you don't really wanna use c++ but this script will be really small and simple, I can't think of anything else to use without a database . BOOL ReadDirectoryChangesW( HANDLE hDirectory, // handle to the directory to be watched LPVOID lpBuffer, // pointer to the buffer to receive the read results DWORD nBufferLength, // length of lpBuffer BOOL bWatchSubtree, // flag for monitoring directory or directory tree DWORD dwNotifyFilter, // filter conditions to watch for LPDWORD lpBytesReturned, // number of bytes returned LPOVERLAPPED lpOverlapped, // pointer to structure needed for overlapped I/O LPOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine // pointer to completion routine ); parameters hDirectory Identifies the directory to be watched. This directory must be opened with the FILE_LIST_DIRECTORY access right. lpBuffer Specifies the address of the formatted buffer in which the read results are to be returned. The structure of this buffer is defined by the FILE_NOTIFY_INFORMATION structure. This buffer is filled either synchronously or asynchronously, depending on how the directory is opened and what value is given to the lpOverlapped parameter. For more information, see the Remarks section. nBufferLength Specifies the length of the buffer pointed to by the lpBuffer parameter. bWatchSubtree Specifies whether the ReadDirectoryChangesW function will monitor the directory or the directory tree. If TRUE is specified, the function monitors the directory tree rooted at the specified directory. If FALSE is specified, the function monitors only the directory specified by the hDirectory parameter. dwNotifyFilter Specifies filter criteria the function checks to determine if the wait operation has completed. This parameter can be one or more of the following values: Value Meaning FILE_NOTIFY_CHANGE_FILE_NAME Any filename change in the watched directory or subtree causes a change notification wait operation to return. Changes include renaming, creating, or deleting a file. FILE_NOTIFY_CHANGE_DIR_NAME Any directory-name change in the watched directory or subtree causes a change notification wait operation to return. Changes include creating or deleting a directory. FILE_NOTIFY_CHANGE_ATTRIBUTES Any attribute change in the watched directory or subtree causes a change notification wait operation to return. FILE_NOTIFY_CHANGE_SIZE Any file-size change in the watched directory or subtree causes a change notification wait operation to return. The operating system detects a change in file size only when the file is written to the disk. For operating systems that use extensive caching, detection occurs only when the cache is sufficiently flushed. FILE_NOTIFY_CHANGE_LAST_WRITE Any change to the last write-time of files in the watched directory or subtree causes a change notification wait operation to return. The operating system detects a change to the last write-time only when the file is written to the disk. For operating systems that use extensive caching, detection occurs only when the cache is sufficiently flushed. FILE_NOTIFY_CHANGE_LAST_ACCESS Any change to the last access time of files in the watched directory or subtree causes a change notification wait operation to return. FILE_NOTIFY_CHANGE_CREATION Any change to the creation time of files in the watched directory or subtree causes a change notification wait operation to return. FILE_NOTIFY_CHANGE_SECURITY Any security-descriptor change in the watched directory or subtree causes a change notification wait operation to return. lpBytesReturned For synchronous calls, this parameter specifies the number of bytes transferred into the lpBuffer parameter. For asynchronous calls, this parameter is undefined. You must use an asynchronous notification technique to retrieve the number of bytes transferred. lpOverlapped Points to an OVERLAPPED structure that supplies data to be used during asynchronous operation. Otherwise, this value is NULL. The Offset and OffsetHigh members of this structure are not used. lpCompletionRoutine Points to a completion routine to be called when the operation has been completed and the calling thread is in an alertable wait state. For more information about this completion routine, see FileIOCompletionRoutine. |

| Coolness: 340350 | Umm, javascript is a web based language.. you're talking about C++ here.. totally off base.
eva, is the site you're using running off of a server with php installed, or is it on your computer at home? |

| Coolness: 92950 | she's trying to get the last updated file from a server directory without using a database, it's not off base. |
| Good [+1]Toggle ReplyLink» moondancer replied on Thu Jun 22, 2006 @ 1:26pm |
| Coolness: 92950 | and a lot of people use c++ for background script on their webpages which is exactly what this is. |

| Coolness: 340350 | find a webhost that supports cgi scripts using C++ and i will then agree with you.
anyway, with php you can do it really easily. [ ca3.php.net ] |

| Coolness: 47555 | neoform:php isn't installed, but i think i found a way to do it. Thanks 4 the suggestions everyone. |

 Coolness: 2749325 | well if you found a way you should post it... |

| Coolness: 92950 | yeah, post it. |

| Coolness: 47555 | lol,
ok well the file is on a unix server, so i wrote a short script to upload the file to the web, and added the simple command: touch -filename which updates the modification time of the file to the current time, this way, the file shows the same modification time as the file which i ACTUALLY want to give the last modified time of. (Since this script is automatically run whenever that other file is modified and uploaded to the net) |
Javascript Anyone?
