Web Forms :: Reduce Image Size While Fetching From Database
Feb 25, 2016
I have stored images in folder each images is more than 700kb so datalist binding process became slow.so it is possible that while loading record and corresponding images from folders Can I reduce the image size or compress images so that record fetching become faster.In database i m stroing image path and image is stored in directory.
I have many image in my page my images size are between 100 -200kb I want redeuce my images size to 4-5Kb ... How I can do it? is there any control to do it?
I am using a sql server 2008 database and I am uploading images to the server using an asp.net webapplication. I have an image column that I use to store the images. I have chosen the database to store the image and not a folder on the server, because the database table will contain only very few rows. maybe close to 10 or 15 rows.
My question is, Do I have to reduce the size (dimensions and quality affecting size on disc in kbs) of the image in code behind before uploading it to the database or do I keep it as is. The total upload size permitted is 200kb. I am thinking that when the image size (size in kbs) is small my webapplication performance will not be affected when displaying them from the database.
I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then Dim stream As Stream = FileUpload1.PostedFile.InputStream Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower If x = ".jpg" Or x = ".jpeg" Then Dim image As New Bitmap(stream)
I have an application that allows users to upload a pdf. I am saving the PDF into SQL (I know already this is not the best practice, but it was not my decision) and I need to some how duing this upload process reduce the size of the pdf.

I need to do parallel processing in my coding because i have 4 sql to fetch data from database which each take me 3-4 minutes.All the tables involved are raw table and that is no way i can reduce the time for the sql.I need to find a way out to reduce the data fetching time.The only thing i canfigure out is to have this 4 sql execute at the same time by doing parallel processing.

In my web application, I have used AJAX Toolkit and my .net version is 3.5. When I run the application and save the page, so many ScriptResource.axd and WebResource.axd generate which makes the file size 200 to 300 KB more big. After doing the same procedures mentioned in the above link, it was working fine as all ScriptResource.axd and WebResource.axd file is removed.
But when I go from one page to another page using on click, then Object Expected Error comes and when I debug it,I found one ScriptResource.axd file containing query string like .axd?d=-bA.like this and Request. GetResponse cannot find the file and it gives 404 errror (File Not Found).

We need through command line to build our site (which we already do using msbuild.exe), but the resulting files are way too many and it takes our to ftp it to the server. I am able to publish the website and reduce its size by ~90%; however, we need to do this through command line not manually using the GUI. I have read many postings but noone is clear on how to do it (and msbuild seems to no be able to do this). Can anyone provide me a link. We are using Visual Studio 2010 and DOT NET4.0
