Web Forms :: How To Get Images From A Database Using LINQ To SQL
Jun 26, 2010
I have a table users which has a column called PHOTO and a datatype of varbinary(MAX)... I have successfully stored image from the database now how do i retrieve it
This is the code which i used to store images in a database
I have a problem with file upload... Im trying to upload two images into sql database.. First i tryied to upload pictures on the single web form..
Everything worked fine, but now I have 2 web forms where Im trying to upload images on the both pages and the problem is that i can not upload all of the pictures i choosed... Some of the images uploaded no problem but on some of them show up server connection lost can not connect to server..
i have made a webpage for user registration where i have to save image of user in data base which i have done successfully but i am unable to retrieve that image
I'm trying to show images that come from a sql query into a GridView column, the problem is that the best solution found in the web searches the database twice for each row.
This solution says that we have to first create a handler (ImageHandler.ashx),
It will receive the ID of the row that contains the image, and then query the database with that ID.
Then it will finally perform something like "context.Response.BinaryWrite((byte[])dReader["Photo"]);" (in this case the handler uses a DataReader, I guess we could use another approach)
We also have to declare the image column in the markup as:
The problem is that, the Grid is bound to a SqlDataSource with a SelectCommand like: "Select ID, Name, Photo FROM Employees", that is already querying the database, then the GridView will execute the handler with the ID in it's query string, so the handler will query the database again for the same row, to extract the image.
Isn't there a way to send the image to the handler, so that it only performs the instruction "context.Response.BinaryWrite..." without having to query the database again?
i have an .aspx website, within the site am planing on having a staff directory, i have setup the search, the results and also a more feature to display all there information.
When you click the More button it is supose to display the text with an image of the person. the images are located on a server and are named via staff ref. below is the code i am trying to use to display but am having no luck so far
I suppose this question has been asked to death all over the web, but I can seem to find a clear cut answer. What I am trying to achieve is as follows: I have a web application that lists various products, their descriptions, names etc and also an image of that specific product. The user will type in a product code or name of the product and a page will pop up with al the previous mentioned info and image or images of that specific product. The problem I am having is: I read somewhere that storing images in a database is 'bad idea' since it effects performance, then I read somewhere else to keep it in the images / or app_data folder. But what would be the best approach and how would I call it from the database (if that's the best way)? And if App_Data / images are the way to go how many images can I put in there (??) already the product catalog has several hundred images of various products. So how would one go about sorting everthing in those folders without having a few hundred images rolling down in my solutions explorer.
Here's my situation. I have a table called Inspections, and another table called Images. The Images table takes the ID of the Inspections table as a foreign key, so the Images tables contains multiple images with the same foreign key value.I'd like to be able to enter an integer of the ID number from the Inspections table and have it return all the records from the Images table with the foreign key that matches this ID, and then load them into a gridview. When I tried using the .ashx Handler approach that I found at this link
in ImageAddress field i have stored physically address of my images and each project has more than one image. how could i show all images that belongs to a project in a GridView?
I apologize if this is the wrong sub-forum for this question, if it is please let me know a better sub-forum to ask this.Anyway, I have a table in my database with a photo column that points to the location of images all under the same root, like this: Y:playerPhotosplayerName.jpg
When I select a specific photo using a stored procedure in my aspx.cs, then read the image path using a sqldatareader like this
while (sdr.Read())
{
string filepath = sdr.GetString(0);[code]....
it works fine and the image shows in Internet Explorer (version 8), but doesn't show in Firefox (version 3.6.4) I think it has to do with the direction of the slash, but I'm not sure. Is there anyone out there that has run into this broswer problem?Basically is there a solution to changing the value of the image's filepath string if the browser is Firefox?
how to display images from a database cant cant seem to find quite what im looking for.
I have a site that allows users to upload their own photos, i would like to be able to display these images, with the discription of the photo underneath or on top of the photo, on the website and allow other users to comment on the photos.
The display can be every photo in the database, later ill impliment a search to narrow it by user later.
Right now I have my database table set up to take the img path, username that uploaded the picture, time it was uploaded, and a description of the photo.
i have a web page in asp.net.vb code and sql database.
the persons number is called PNUMB and i have stored all photos of persons in a folder with the persons number (PNUMB) as their file name. when i search for a PNUMB i want to display the photo of the persons whose dtata is displayed. how i sit possible
I have one folder which contains the jpg images. That images i want to store binary format into sql server database. And finally that images binding in the DataGrid.
I have been debating back and forth between using a database or the file server to store images for users. Finally when I decided to use the file server I found it difficult. What I am trying to do is give a user the option to save multiple profile pictures. I have looked all over for tutorials on how to save to the file server but could find nothing related. Essentially what I would like to do is create folders for each user and their images. I am having no luck. Does anyone have example code or links to what I am looking for?
