Detect proper file format?

Detect proper file format?

Detect proper file format?

Hello!! Uf!!! Finally I"m about to finish this "bloody" project which has caused me nothing but blood, sweat and tears. (but also I've learned a lot!)

I'm using this script attached to a button to load external images into the cast :

on mouseUp me
  set MUIobject = new(xtra "MUI")
  result = fileOpen(MUIObject,"Xtras")
  MUIObject = 0
  importFileInto member(5), result
  sprite(115).member = member (5)
  member(5).name = "image1"
  sprite(115).height = 252
sprite(115).width = 252

I want to load only images, I would like to add some lines(I hope just a few) in order to reduce the amount of "allowed" kind of files. Basically I would like to prevent that a wrong format might be loaded, for example when somebody tries to load a WAV or AIFF(among others) file instead of a JPG by mistake(Yeah, I know! who da' hell would do that mistake, but it does happen!) the projector return a message like "sorry you are trying to load an incorrect file format, please try with another one" or something like that.

Links, suggestion, opinions, comments, and mostly help will be appreciated.

Thanks in advance.

RE: Detect proper file format?

You have to rely on the file extension i.e. ".JPG". This will not filter out the files with wrong extension, e.g. a WAV file with .JPG extension, but you have to live with that.

On Mac you can use Buddy API baFileType() function to determine the file type, but this is only for Mac.

I would actually use Buddy API baGetFilename() to get the file name instead of using MUI fileOpen(). baGetFilename() offers far better control over the dialogue box. For example you can set it to display only .JPG files - this is basically what you want!

Finally, this is working perfect!!! Thanks to TonyDomigan from DOMAJ Forum. And Steve Karmen from Director Online. Thanks a lot, actually I used Steve advice and it worked but using FileXtra4, but I prefer to go on a solution because the filtering in FileXtra4 does not work 100% ok. Rather go for the old fashion Alert Windows. Thanks a lot!!

on pointerLoad me

set MUIobject = new(xtra "MUI")

--| change
theDirectory = "Xtras"
result = fileOpen(MUIObject,theDirectory)

MUIObject = 0

resCount = result.char.count
fileExt = result.char[resCount - 2..resCount]

if fileExt = "swf" then

importFileInto member(55), result

sprite(167).member = member(55)

sprite(167).height = 71
sprite(167).width = 71

--| change
if result<>theDirectory then
alert "Wrong file format.Only Flash files(*.swf) are allowed."
end if

end if
