DataSource Controls :: Saving And Retrieving Images From Sql Server 2005

Jan 5, 2010

I am facing a problem with retrieving an image and showing it on asp.net grid. I migrated MS Access database to sql server. Image are visible in Crystal report when fetched from the same database (migrated sql server database). But same images are not visible in ASP.Net grid view or simple asp.net image control. Following is my code

SqlConnection oConn =
new
SqlConnection(ConfigurationManager.ConnectionStrings["csr"].ToString());
oConn.Open();
SqlCommand oraCmd = oConn.CreateCommand();
oraCmd.CommandText = "select top 1 photo from [test] where photo is not null";
SqlDataReader dr =
null;
dr = oraCmd .ExecuteReader ();
if(dr.Read ())
if (dr["photo"] !=
null)
{
Response.ContentType = "image/gif";
Response.BinaryWrite((byte[])dr["photo"]);
}

This function is getting called from another page . "hlopen" is hyper link in the grid. hlopen.NavigateUrl = "GetPhoto.aspx?id=1";

Modules :: HttpHandler For Retrieving Images?

Feb 17, 2011

I have an application that uses an Asynchronous HttpHandler for retrieving images from a fileshare It appears the performance of this is quite poor. I have two questions:1. Does it make sense to use an IHttpAsyncHandler for this or will an IHttpHandler work fine? I have four images on a page that need to be loaded this way and it seems that they all load sequentially instead of in parallel. Since we have some JavaScript in the body onload event, it doesn't get excuted until all four images are finished loadingy bearing on this.

Storing And Retrieving Images With MVC And Sql Server?

Jan 15, 2010

I am designing an prototyping an app the needs to store images, similar to facebook. This will be a public facing site and I am not sure how many users I will end up with but what I am looking for is a way to efficiently retrieve them.

So far I am thinking of storing them in SQL Server varbinary columns. I have the upload code and the storage code for that. My concern is retrieving them. I can retireve and build the image tag on the fly but I am worried about having to hit the database for each one.

I have been thinking about getting all images for a user and caching them in the asp.net cache for 10 to 30 seconds. I have never had to do something like this so I would be interested in hearing a few different approaches. Obviously the images can vary in size and I was thinking about defining a size limit, but I haven't gotten that far yet.

Retrieving Images From A Mysql Longblob Field?

Feb 25, 2011

I store images in mysql as a longblob. The image control only takes an imageurl, so I have to have an ashx page serve up the images and then the image control uses that page as the imageurl. It works, but does that mean I have to do this for each image, kinda gets complicated for a lot of images.

Or should I just store the images on the hard disk? I am worried though about the space I would need if my site grows, as I want it scalable.

Retrieving And Displaying Multiple Images Dynamically?

Apr 28, 2010

I want to create a page that will dynamically change the images displayed, based on which link the user clicked to get there. For example I have different movies listed and when you click a link for one of them it displays all the images for that movie. I need it to be on one page because at the moment I have hundreds of pages and its very hard to manage. I have the images stored in BLOBS on SQL Server 2005. I can retrieve all the images for a certain category and store the Image data for each one into a list of images. What I cant do, is display the images on the page. I can display one image by using the queryString to get the image by ID, then putting the Eval code into an asp:image, but I dont know how to do it for multiple images.

I'm quite new to ASP.NET and i was wondering if someone could answer some of my questions.1. What is the difference between a DataTable and an Array? Is the DataTable a serverside control? Is it exposed to the user?2. Does the reader retrieve the column names? If so- how can I capture them? Are they the first row?2. Is it possible to populate an Array using the following sort of code, and if so- how?:
