hi
i'm working on VB.NET 203
and i'm working on application that read Metadata from Photo Take it from
Digital Camera.
i'm use this code:
Dim imageX = New Bitmap(PhotoFul lFileNameX)
Dim propItems As PropertyItem() = imageX.Property Items
....
....
....
it's working good
but after i read information i need delete this file with:
file.Delete(Pho toFullFileNameX )
but i have this error:
An unhandled exception of type 'System.IO.IOEx ception' occurred in
mscorlib.dll
Additional information: The process cannot access the file
"filename.j pg"
because it is being used by another process.
that's mean the file still under open with (bitmap function)
what i must do to close this connection???

Probably you did not dispose imageX before deleting the file. If you want to
delete it and still keep a bitmap in memory, you have to copy imageX to a
new bitmap and dispose imageX before deleting the file.
To copy the bitmap, you can simply write:
dim bmpToKeep as bitmap
bmpToKeep = new bitmap(imageX)

thx
but how i can dispose imageX ?

Try opening the image using a stream, which you can close before
deleting:
Dim file As New IO.FileStream(" c:\temp\image.g if",
IO.FileMode.Ope n)
Dim image As Image = image.FromStrea m(file)
file.Close()
IO.File.Delete( "c:\temp\image. gif")
Hope this helps

imageX is Bitmap Object

I can't reproduce this. Dispose is not an advanced member, so it should be
shown always. Isn't it listed via intellisense or doesn't it compile?
Armin
Bitmap inherits from Image so you should be able to do what you want.
Dim file As New IO.FileStream(" c:\temp\image.g if", IO.FileMode.Ope n)
Dim b As Bitmap = DirectCast(Imag e.FromStream(fi le),Bitmap)
file.Close()
IO.File.Delete( "c:\temp\image. gif")
hi
when i did what you tell, i get the Error Message:
A generic error occurred in GDI+
maby image from file stream not support metadata.

I've two scripts, one to upload images, another to delete them. The

When I write scripts for deleting records in databases, I tend to do it in
this fashion:
- delete link passes ID to a delete.aspx page
- delete.aspx page queries db using that ID to retrieve the file
information
- page displays file information with a 'are you sure you want to delete'
confirmation button.
- upon clicking said button, I delete the record.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
