Both of these solutions causes an error in my Windows form. The error is 'parameter is not valid' and points to my programs.cs file.

I have broken my form down to just a PictureBox and a CommandButton object.

The click event of my CommandButton is:

            string myImage = @"C:\mydir\myImage.jpg";
            using (System.Drawing.Bitmap o = new Bitmap(myImage))
            {
                myPictureBox.Image = o;
            }

The above causes an error and the image does not display. My goal is to display the desired image but not have the image locked. What am I missing?

Thanks,

Jerry

>>I have a VS2008 Winform. I am trying to display an image in a PictureBox at runtime. I use the below code to display the selected image. This works and the image is displayed on the form, however, the PictureBox object keeps the file opened. So if I try to rename or delete the file from Windows explorer, Windows tells me that the files is in use.
