Hi Everyone,

This is my first UDF, but I thought I would share it. It allows you to read, write, and clear the different file properties, including title, subject, author, etc.

To use this UDF, you must have the dsofile.dll in the script directory.

;===============================================================================
;
; Function Name:   File Property Management
; Description:      This utility is for reading/writing file properties
; Parameter(s): _FileProperty($fFile, $fProperty = "Title", $fValue = "", $fMode=0)  
;                  $fFile - File path of file to be adjusted
;                 $fProperty - Property to be adjusted (title, subject, category,
;                                keywords, comments, company, author)
;                  $fValue - Value to insert into field
;                 $fMode - 0 for read, 1 for write, 2 for remove
; Requirement(s):  DLL File in script directory - dsofile.dll
; Return Value(s): Property read if the read mode is specified.
; Author(s):        Andrew Goulart

Func _FileProperty($fFile, $fProperty = "Title", $fValue = "", $fMode = 0)  
    _DLLstartup()
    $return = ""

    Global $oMyError = ObjEvent("AutoIt.Error", "ComErrorHandler"); Install a custom error handler
    $objFile = ObjCreate("DSOFile.OleDocumentProperties")
    If $g_eventerror Then Exit
    $g_eventerror = 0
    If Not IsObj($objFile) Then Exit
    
    $objFile.Open($fFile); bind to the summary information metadata attached to the file.

I am surprised that Ptrex did not already show its enthusiasm

This did not come to me as something new.

Because it was already discussed long time ago ?!

Did you miss that thread.

EXAMPLES

; READING A FILE'S TITLE PROPERTY
$filename = FileOpenDialog("Please Select A File", @DesktopDir, "All Files (*.*)",3)
$filetitle = _FileProperty($filename, "Title", "", 0)
MsgBox(64, "Title Property for File: " & $filename & ".", "The title of the file selected is " & $filetitle & ".")

; WRITING A FILE'S AUTHOR VALUE
$filename = FileOpenDialog("Please Select A File", @DesktopDir, "All Files (*.*)",3)
_FileProperty($filename, "Author", "Felanor", 1)
$fileauthor = _FileProperty($filename, "Author", "", 0)
MsgBox(64, "Author Property for File: " & $filename & ".", "The author of the file selected is " & $fileauthor & ".")

If you need any more examples, please let me know. The examples provided will work with either the original code, or the updated code that can be found in the codebox above. I included a bit more error checking.

@ptrex, I did not realize someone else had already done this. I was having a devil of a finding some existing code to extrapolate from. I did find one article prior, but sadly I dont remember who wrote it, however, it wasn't in any convenient UDF format. I am hoping that this will simplify the process for anyone who needs to modify file properties.

I know it's been over a year since you wrote this, but I just found it. It is very useful! Thank you!

Two comments:

1) As an UDF, it should not do registering and unregistering of DLL... it's a slow process. Why not just make it a required item to register before hand?

2) There is a note about UDF should be careful about handling the COM Errors, since there can be only one handler per instance of the running code.

Thanks again!

Try running it as an x86 script, and not as a 64 bit program. Try adding this line"#AutoIt3Wrapper_UseX64=n" to the top of the script and see if that helps.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.
