In the code below I receive an exception error because the target file is being used by another process. I know this to be false because the target doesn't exist. It seems like the application believes that the file is still in use by the application. My concern is that I do not think that I still have a reference to it. In the removeImage function, I remove the item from the image list and list view controls and refresh the list view control to ensure that it is no longer even on the screen. No joy.
Thanks in advance for any help, also if I have questions like this do i need to include the entire project or just the area of confusion?
