smallImageList.Images.Add(Image.FromFile(ConfigurationSettings.AppSettings["doc"]));

Can anyone pls guide me.

Answer 1

Try adding the current running path:

smallImageList.Images.Add(Image.FromFile(Path.Combine(AppDomain.CurrentDomain.BaseDirectory, ConfigurationSettings.AppSettings["doc"])));

Answer 2

Try using a tilda...

value="~\Icons_Microsoft Office Excel 97-2003 Worksheet.ico"

Which should start you from the application root.

Answer 3

You might need to concatenate that with System.AppDomain.CurrentDomain.BaseDirectory.

I'd guess that FromFile is relative to the current working directory which is prone to change. The other thing to consider would be embedding the images in the assembly

Answer 4

Your working folder has somehow been modified during your program execution, you have to find your own path.

Try this:

using System.Reflection;
string CurrDirectory = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

smallImageList.Images.Add(Image.FromFile(Path.Combine(CurrDirectory,ConfigurationSettings.AppSettings["doc"])));
