• sangminny Why ImageList can not dispose the image it contains?

  It's strange that ImageList can not dispose the image it contains, when I invoke imagelist's dispose method. private void Form1_Load( object sender, EventArgs e) { ImageList images = new ImageList (); Image image = Image .FromFile( @"xxx\bookmark.png" ); images.Images.Add(image); images.Dispose(); this .pictureBox1.Image = images.Images[0]; } I have invoked imagelist's Dispose method, but the picturebox can still show the image in imagelist. Why Thank you very much. I will do a little test the solution....and I response... ImageList inherits its Dispose() method from Component. Component.Dispose() does nothing but remove the component ...Show All

• Michael Hansen Abstract Generic Base Classes... how to refer to the derived type?

  Hello all, my first time posting here on MSDN, so be easy on me. :) I have an abstract base class that takes a generic type parameter to strongly type a member.

From the User, object, I can only pass back either a type "object", type "IBusinessObject", or type "BusinessObjectBase< ...Show All

  Hi, I am wirting a program to execute a process under a user (B's) context ie. by impersonating a user. Assume Im the user (A).Following are the steps I have followed : 1.
