reterivine image from database from Access Database in C#.net(Windows Application)

First of all, you should EDIT your first post, not write a new one. What makes you think that the people reading this have any idea what was written before ? Second, post the code, the EXACT error message ( which you should also have googled as your first attemp to fix this ), and explain exactly what you've done and where it goes wrong. Based on this post, no-one can possibily help you, not without giving of our time to try to piece together what it means by going to search for your old posts. I did go and look - and sure enough, the error means that you have failed to properly store an image in your database. I can't imagine a better answer than the ones you were already given, unless you provide more info, such as how the images were stored in the first place. Please edit your original post, not this one.
