Display Image From Memory Using File Upload?

Mar 29, 2010

So I'm working on a site that is going to need a file upload control where the user would be able to upload an image, and then the page would postback causing the image to appear for their viewing (before they submit the data to the database, the image is being stored as type image). What I do now is have my own private web form where people send me their image, I format it accordingly and use the following simple code to upload it:

byte[] newimage = fileUpImgFile.FileBytes;
var myDataTable = (from item in context.TypeSet where item.Number == txtBxNumber.Text.Trim() select item).ToList();
foreach (Type item in myDataTable)
{
item.Photo = newimage;
}
context.SaveChanges();

Which works, but in this case, it would only work if the record exists already in the database so the person would have to save the data, then go back in and upload the image (inconvenient and inefficient). Is there a way to upload it, store it in memory, and then display it, without saving it to the database?

Valum File Upload - Works In Chrome But Not IE - Image Img = Image.FromStream(Request.InputStream)

Dec 6, 2010

I'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

Accessing Image File Of Client's Machine (without Using File Upload Control)

Apr 14, 2010

I want to access one image file residing in C: of the client's machine. I know with the help of file upload control (or say input type=file), this would be easy. Due to nature of my application (Its a KIOSK application), user is not expected to select file. I am just wondering how should I implement reading file without using file upload control. I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

Web Forms :: Upload An Image And Display It On Next Page?

Aug 7, 2010

I'm trying to allow the user to upload an image to the server (this part works) and display it on the next page (this part doesn't). I've got two files, imageuploadtext.aspx, which has the following code:

[Code]....

And the second file is imageloadtext.aspx, which has this short code:

[Code]....

As I said, the upload works fine and the file is received. But I can't get the source to display the correct image on the second page. Could it be to do with the fact the first page is VB and the second is C#? If so what code would I replace the C# with for it to work with VB? By the way, I'm currently getting a ";" expected on the image source line which I'm not sure where it goes, that might be it?

I can't use NullImageUrl as the Images are not stored in the database. I can't use the solution found on [URL] as an ImageField does not accept an ID attribute.
