Refreshing.
-
Hello! I just uploaded my first ASP.NET 2.0 application to my new webhosting provider. At the moment I have a fractal drawing program on it. This code worked perfectly on my PC with Web Developer. Unfortunately, on my site it doesn't work, because when you want to draw a second picture you need to refresh the screen with the browser to get to see the new picture. This picture is stored in a bmp file in my root directory. I looked at a Refresh() method, but this method is in System.Windows.Forms which isn't available in Web Developer. Can anybody tell me where to search to find an answer to this problem? Do I need to add a statement to the Page_Load method maybe? Ranger. Novice.

I have seen an issue where if you reuse the same name in the bmp file there is a caching problem. If you are doing this, you have two options. First you can choose a new name for the bmp file each time. Second you can force garbage collection which seems to help. Hope that helps. Ben

The image is cached by the browser. Add a unique value as a querystring to the image to make it unique. Example:
You can use a large random number as a "unique" number. The risk that you hit the same number twice is so small that you can disregard it.--- single minded; short sighted; long gone;

I tried this, and I am sure it will solve my problem, but that I now encountered the problem that I couldn't figure out how to set outputPicture.ImageUrl to some value. Somehow the Url for this picture kept resetting to an empty string. Could someone say anything sensible about this? Ranger. Novice
