The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

how do we retrieve images from an image folder into a listview control where folder path is taken from ms access

Asked by tolgss in .Net Editors & IDEs, Microsoft Visual Basic.Net, Visual Basic Programming

Tags: vb.net 2005, vb.net 2008

I have an imageDesc and imagePath columns in a table in ms access. Now I need to create a connection to MS Access to retrieve these two columns. Once retrieved I need to display the imageDesc column and its corresponding images from the directory folder referenced by the imagePath column (eg c:\image1.gif). I don't want to display column headers in the listview.

So basically I have a listview control with images and a description of each image in thumbnail style view.

I tried using OleDBDataReader to access the columns and managed to display images but it seemed to show the same image for all image descriptions.

the below code was working (but not as expected) and now it has some error but overall it gives you an idea of what i'm trying to accomplish

Any sample code will be appreciated.
