MVC :: Uploading Working With And Then Saving A Resulting Image?
Jul 18, 2010
I have been messing around with uploading working with and then saving a resulting image.
However at the moment im getting errors in the outputted image, even with very simple code which takes the filebase, puts it into an image object then saves it back out.
Also i would like to know if there is a method in MVC to check the file extension or somehow determine wether it is an image file.
Here is my code:

I've got a project that's going to go on a dedicated server environment. I'll be uploading images to the server, but saving them outside of the virtual folder path of the actual website, like so:
protected void UploadImage_Click(object sender, EventArgs e)
{
string newFile = "C:\Images\myImage.jpg";
this.cb_fuMainImage.PostedFile.SaveAs(newFile); // from webform <input id="cb_fuMainImage" type="file" runat="server" />
}
Now, this works fine on my home computer. Is there anything I'll need to do with IIS or ASP.NET (possibly in web.config) for this to work properly on a production machine? Settings or permissions that may need changing?...
It will be on Window 2003 with IIS6 and ASP.NET 3.5 SP1.

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)

We have a scenario where we would like to allow our users to upload images to the site. We are running on ASP.Net. A quick search did not result in anything good. It would be great if the control is free/open source but we do not mind paying a little bit.

I creating a page where our clients can view advertising images and then able to download the images in different file formats. So I need the images and the different download types all saved into the same row in the database so that when I go to display them on the page when they select a picture the right download links will be there. So here where my problem comes in, I don't know how to code it so that I can insert mulitiple file paths into the database at once. The images are saved in a table called images. The downloads are saved in a table called Image Downloads.
Here is the code for the page I have it coded to submit the images to the database but not sure how to add the rest. I have got three different sql datasources for each table not sure if that's the way to go.

I would like to be able to read an image based on a url hosted elsewhere. To be clear, this is a legitimate service that is provided and they do allow caching of data, so I'm not trying to steal someone elses data.
So far I have the following code:
public static byte[] GetBytesFromUrl(string url)
{
byte[] bytes;
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
WebResponse resp = req.GetResponse();
The area that I'm looking to improve on is the emboldened line. I think it would be better to read in say 1024k chunks until the file end. Can anyone help me out with the syntax for this?

I apply a watermark to an uploaded image.
After that I want to save the changes, but I am not able to delete the original file nor can I rename it because I get the following error.
The process cannot access the file because it is being used by another process.
I have already disposed all objects related to the "watermarking process".
It seems that the uploaded file is being locked by IIS for a period of time while I need to manipulate & save the file right after uploading.
