Web Forms :: Image Upload Control Which Strips The Size Before Uploading?
Nov 5, 2010
i 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

Users 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?

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 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.

I Used AsyncFileUpload(one of Ajac Control Toolkit Controls) to Uploading User's Image. this works well. But i want to change the image url of an image contorl to uploaded image url. how can i perform that? I put Image control in a Update Panel:
[Code]....
in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!

I'd like to allow users to upload a .pdf file via the file upload control (if that's the best method), save the file to the db and then retrieve it so they can click on a link and open the .pdf they've uploaded. I've been looking for a tutorial on how to do this but keep running into methods of saving the file directly on the server in a directory, not in SQL server (using Linq and VB by the way)

Uploading file using upload control resulted in access denied
does not have write access to 'C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET Files'.
I gave the access to that particular user using web config :
<identity impersonate="true" userName="username" password="password"/>
but then that resulted in the above error. My intension is to upload the file for a perticulr folder.
I know the path.
I am not able to grant the persmission for the folder from control panel. Is there any work around.

How can I display photogarphs in an image control so that they are all the same size for an online catalogue without distorting the actual image.
I have taken the photos with a digital camera, loaded them in to Photoshop, cropped the image and finally resized the images to an acceptable size (while constraning proportions to avoid image distorsion).
The problem is that the images all have different height dimensions as while resizing i was able to choose the width that I wanted but as I had to constrain proportions to avoid distorsion, it caused the heights of the images to differ.
On my web form I have an image control that is set to the same width as the images but as the heights of the images differ from one and other, it is impossible for me to set a fixed height that will prevent some of the images being distorted when displayed in the image control.

I 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?
