Question Incapable of moving image file

[bigklaxer]

Hey, I've been working on a program that will be used to categorize image files. However, whenever the program actually gets to the point where it will move the image, it freezes and says it cannot run the process because the file is already in use by another process. The following is the code I used to set the image to be organized in a picture box, and then to clear the image, and then to move it, respectively.

pctbxFileViewer.Image = Image.FromFile(txtSource.text)

pctbxFileView.Image = Nothing

System.IO.File.Move(txtLocation.Text, txtDirectory.Text & folderName & newName & ".jpg")

I was wondering if anyone could tell me why this is. Thanks in advance.

Before setting a new Image or dereferencing it you have to dispose the existing: Image.Dispose Method (System.Drawing)

pctbxFileView.Image.Dispose()

If you want the image to remain in picturebox after file is moved you can load it from a stream instead, see http://www.vbdotnetforums.com/graphics-gdi/21341-how-do-i-remove-reference-file-gdi-exception.html

Cool thanks!

Also, I was actually experimenting a little bit with the code and I found that if I do pctbxLocation.Load(image) then it actually works with out bringing up an error. Could anyone explain the reasoning behind this?

PictureBox.Load uses the Image.FromStream method.
