[RESOLVED] Accessing Private Stuff

[Xenobius]

Hi all, How do you know the properties of a picture:

it's creation date
it's size in pixels


thanks guys

any help is welcome

Use the System.Io.FileInfo class, get the CreationTime property

There probably a more effcient way but here goes

dim aImage as image
aImage = aImage.FromFile(PicPath)
 
Dim res_V As Single = aImage.Width
Dim res_H As Single = aImage.Height

I've always wondered how windows is able to determine the image's dimensions when you mouseover it (in WinXP at least). It must be an API of some sort...

        MessageBox.show(fi.CreationTime.ToShortDateString())

I think it probably is something like that, or it may be a background service of some kind. The way it seems to me is that windows needs to know how to open and read all the different kinds of header blocks found in different image file formats. Jpegs store all kinds of info, bmps store hardly anything.

Did you ever find out who nicked your camera?
