View 1 RepliesC# - How To Calculate The Optimum Chunk Size For Uploading Large Files
Sep 9, 2010Is there such a thing as an optimum chunk size for processing large files? I have an upload service (WCF) which is used to accept file uploads ranging from several hundred megabytes.
I've experimented with 4KB, 8KB through to 1MB chunk sizes. Bigger chunk sizes is good for performance (faster processing) but it comes at the cost of memory.
So, is there way to work out the optimum chunk size at the moment of uploading files. How would one go about doing such calculations? Would it be a combination of available memory and the client, CPU and network bandwidth which determines the optimum size?
EDIT: Probably should mention that the client app will be in silverlight.
Web Forms :: Resize Small And Large Images To Match The Height And Width Of Image Control
Aug 18, 2012In my Web page,I have a Div section with height=302PX and width=302PX.
In another page,I had a File Upload control. When we will upload the image,then the image will be displayed in that Div section.
1.When the image is large,it should be re-size and display in that particular Div section completely.
  For Eg:The image size like 350PX*350PX and 1024PX*1024PX, it should be re-size to Div Section size has 302PX*302PX.
2.When the image is Small,it shouldn't be re-size and display in that particular Div section completely.
  For Eg:The image size like 50PX*50PX,100PX*100PX and 302PX*302PX ,it shouldn't be re-size and display in that Div section.
  For Eg:The image size like 15PX*15PX these will appear very small.But When uploading the file these images also should displayed completely with as it is  in that  Div section.But the image will displayed neatly.
3.If there are any tools for these type of conditions using ASP.Net.
Web Forms :: Uploading Image (max Size And Position)?
Oct 5, 2010Users of my C# web application can upload images. I have configured the max upload size in the web.config file to maxRequestLength="1024" and executionTimeout="180".
How can I check the upload size before uploading? (do you have examlpe or url?)
Another option might be to check the dimensions?...
Some web application allow the user to crop the image at client side. Do you have an example of this or url?
Web Forms :: Image Upload Control Which Strips The Size Before Uploading?
Nov 5, 2010i am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes
b. is there any dotnet control that might be userfriendly to all OSes
Reduce The Size of The Image In Code Behind before uploading?
Mar 18, 2011I 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.
VS 2008 - Image Format To Save With Smaller File Size After Uploading With Website?
Aug 11, 2011I have written a website and let the user upload their photo. It also resizes the picture to 400 x 400 and crops automatically to the center part of the picture. All of this works good but each file is about 355K each for JPG and PNG file formats. I just tried GIF and it is 49K but the picture is grainy when saved this way. Is there any way I can get the picture to a smaller file size with keeping it at 400 x 400? I really thought PNG would be the way to go and was surprised by it being the same as jpg. I don't want to lower the quality either for JPG files.

Web Forms :: Finding Client File Size Before Uploading?
Sep 28, 2010I need to upload images from client to server as follows:
1. Server is passing the client a file name
2. Client is checking file extensins to ensure it's an image then issues a __dopostback to the server.
3. Server uses the FileUpload control to save the image on the server.
I have that all covered, but, if image is too large, the upload fails with the following error: 'System.Web.HttpException: Maximum request length exceeded.'
Is there a way to check file size on the client (without the use of ActievX which also errors out), before it is passed back to the server?
