vb.net Load JPG in a Picture Box without Locking File

[Marcolino]

Hy Guys,
I have a problem loading JPG in a Picture Box.

I need to load a jpg files into a PB and then unlock the original JPG.
I'm using following code:

Dim picture1 As PictureBox
Dim OriginalImage As New Bitmap(FilePath ) 'Load orginal
JPG
Dim iImage As New Bitmap(Original Image) 'Copy ii into a
tmp
OriginalImage.D ispose()
picture1.Image = iImage
iImage = Nothing
OriginalImage = Nothing
This code will work sometime yes and some time not.
I mean that sometime the file will unlock immediately, sometime it
takes to unlock 10/20 seconds and sometime never unlock.

Any help would be appreciated.

Many Thanks

Marco

I need to load a jpg files into a PB and then unlock the original JPG.

Load it into a memory stream(i.e., Use the FileStream object).
Decode the image using the Bitmap constructor for a stream object.
Once loaded and decoded from the stream, there is no need for the system to
retain a file lock on the original file.

Probably the easiest thing is just to draw the image on a new bitmap
created in memory
and, then, use this bitmap as image for the picture box.
