DataSource Controls :: Sample Code For Uploading And/or Retrieving Images Needed?
Jan 1, 2010
i am looking for some sample code in order to upload and/or retrieve images stored in a database.even the web is full of samples, i was not able to find one without using blobs as i would like to save only the directory of an image when it comes to the place of storing. the reason behind is that i do want to have my database small for some reason and therefore only want to save links to my images inside.

post the C# source code for uploading images to a database, and then showing it to the user?? I have tried now for 3 weeks with no luck... Maybe we should recommend to Microsoft to add a file upload html helper method to MVC 3?

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";

Any tips on where to start looking/investigate Re how to code pages to only load/render images when that part of the page is visible ?
e.g. Recent Google Image Search and Facebook interfaces.
Up to now my Ajax experience has been limited to extensions + Toolkit so not sure where to start looking.

I have developed a Portal (Request submission) which sends an Email and also it updates all values to the Database. What ever values gets updated to the database, will be sent as an email message to an address. It works fine. I need a Unique number to be generated for a Request submission which has to be sent in the Email message and also it has to be updated in the database. I use SQL Server 2005 and Framework 2, C# laungauge.

I am looking for sample code where a button click on the server side will spawn a modal child page, having couple of controls such as textboxes and a button, where one could enter values in the text boxes and click the button; once the button is clicked, the page should postback to the parent page, where the entered values could be read. There is a video on this site about AJAX control kits describing modal popup, but unfortunately it wouldn't serve my purpose.

anyone use/ know of any library or website with code snippets or samples with many of the mundane boilerplate code and/ or functions like data access, data scrubbing, recursive routines...
preferably c# since most of .net in the real world is c#. VB is ok too.

i have two buttons, which point to some onclick-methods in my code-behind file. inside these btn_click-codes i want to start adding pure html-code to my page, which was told to me in this forum having done by using ascx-files. note: there would be no code-behind in case of using the ascx-files.
however i do not see a possibility to load these ascx-files within btn_click-code? how to do?
in order to give you an idea of my html-code i have pasted two of them here:
[Code]....
maybe this is the complete wrong approach (as i.e. i believe that body-tags should not be included in .ascx-code). in this - how to do better?

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.

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.

There are sample codes on the net for OpenId Client but none for OpenId Server. Do you know some? I know about dotnetopenAuth but there seem to be no tut on how to use as OpenId Provider. I don't even know if it can do that. Maybe it can just be used to create openid consumer app.
