Udf: Get Extended File Property

[Simucal]

Alright, so maybe you all havent been waiting for something like this. None the less, I think it is neat.

This function will give you an extended property of a file. Examples would be the width or height of a video or image. Or the duration/bitrate of a song or video. How about the artist/album/song number of an mp3/wma music file? The list goes on.

Enjoy .

Example:

#include <extprop.au3>
$path = FileOpenDialog("Select a file to read attributes",@ScriptDir,"All (*.*)")
$prop = _GetExtProperty($path,21)
ConsoleWrite("Property #"&$i&": "&$prop&@CRLF)

Example2:

#include <extprop.au3>
#include <array.au3>
$path = FileOpenDialog("Select a file to read attributes",@ScriptDir,"All (*.*)")
$prop = _GetExtProperty($path,-1)
_ArrayDisplay($prop,"Property Array")

EDIT: Have added a "-1" option that will return an array with all properties.

EDIT: Also, have added some error checking to ensure the file exists.

EDIT: Requires Beta!!

I like it. If you could make a function to change the tags of a mp3 file i would be in heaven.

Looks good Simucal but it doesn't show any version informations on AutoIt EXEs

[blindwig]

Nice info function. How about a new feature:

If I give you -1 for $i_prop, you give me an array with all the info in it.

See also my _FileListToArray2() function

Nice suggestion, I'll implement this tonight.

Very Useful simucal.

Thanks for the contribution, added to my Custom UDFs

Thanks

Looking forward to the update as suggested by blindwig

Just updated it. Now has a -1 option to return all to array and added some error checking.

[marfdaman]

Very useful this! Thumbs up!

Regards

[Simucal]

Thank you.

I'm thinking about cleaning it up and submitting it to be included with AutoIt. I think being able to get a files extended properties should be easily available.

[marfdaman]

Yes that's true IMHO, all these properties can come very handy in a lot of situations.

Personally, I'm implementing it into my mediaplayer, this works *way* better than some of the ID-3 udf's I have seen on this forum.

[rakudave]

this is VERY cool!

thanks Simucal

[ConsultingJoe]

Good job, Thanks. Very useful

Simucal,

Is there an option to get the sample rate of a wave file?

[Confuzzled]

BitRate = 22???

[marfdaman]

BitRate = 22???

No no sample rate is something different from the bitrate: the sample rate shows to what frequency the soundstage extends (for example 44 khz, this means that the 2 channels [stereo] each have a soundstage up to

22 khz), the bitrate shows how much space is used per time unit (seconds).

[trids]

Very cool

.. I agree 100% .. good luck!

[tazlikesrobots]

Is there a way to retreive the original file name property.

[Briegel]

Good job, that's what I'm looking for, thanks

[piccaso]

is there a way to alter/set the 'FileVersion' property ?

[randall]

I totally agree!!!

This is essential, you can use it for a million things, and it goes very well with the initial purpose of autoit as a macro and Windows automation language.

I am going to use it for some image processing to get the width and height, but i am sure it will also be useful in the future.

Thank you very much!
