[RESOLVED] File Type Info

[boku]

I'm having trouble getting a files description...

ie

".txt" = "Text Document"

I do not want to use a registry lookup, as i doubt this is the way other programs do it ... i don't find it to be very efficient...

Does anyone know any other ways of doing this?

e.g.

lvitem.SubItems.Add(System.IO.File.GetAttributes((MyFiles(i))).GetType)

GetType is a method used to get the actual .NET framework type of a given object.

File extension descriptions are in fact stored in the registry, and that is how you should go about retrieving them.

How is it not very efficient to use the registry for this?

Well I had a quick browse through the CLASSES_ROOT node and tried to find, BMP for bitmap

found

".bmp"

description

"Paint.Picture"

Although when I right click > properties > Type Of File

it says

"Bitmap Image"

2 totally different descriptions ... so I'm just wondering where does the file properties window get its info from? and can I use it?

[kleinma]

what about this?

        Dim myExtensionToFind As String = ".bmp"
        Dim myExtensionType As String = My.Computer.Registry.GetValue("HKEY_CLASSES_ROOT\" & myExtensionToFind, String.Empty, String.Empty).ToString
        Dim myExtensionDescription As String = My.Computer.Registry.GetValue("HKEY_CLASSES_ROOT\" & myExtensionType, String.Empty, String.Empty).ToString

        MessageBox.Show(String.Format("File Type {0} is : {1}", myExtensionToFind, myExtensionDescription))

the myExtensionDescription always draws a blank :S for some reason mate?

the myExtensionDescription always draws a blank :S for some reason mate?

Can you give an extension example that Klienma's code would return a blank description?

Nevermind, just had to move stuff around bit.

Excellent work as usual Klienma
