Question

I use:

Dim bmi As New BitmapImage(New Uri(fiInfo.FullName, UriKind.Absolute))
bmi.CacheOption = BitmapCacheOption.OnLoad

this does not Use OnLoad
And file still is locked to overwrite on harddisk. Any idea how to unlock?

Regards

As shown in the question you link to, you’d need to call BeginInit and EndInit, like so as well as set the UriSource property:

Dim bmi As New BitmapImage()
bmi.BeginInit()
bmi.CacheOption = BitmapCacheOption.OnLoad
bmi.UriSource = New Uri(fiInfo.FullName, UriKind.Absolute)
bmi.EndInit()
