Valum File Upload - Works In Chrome But Not IE - Image Img = Image.FromStream(Request.InputStream)
Dec 6, 2010I'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).

I want to store this file in Images folder of server. I am beginner to WCF. Should I look towards WCF?

View 1 RepliesDisplay Image From Memory Using File Upload?
Mar 29, 2010So 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?

View 3 RepliesImage Upload Taken By Mobile Device To File - Orientation?
Apr 29, 2016It seems that when trying to upload(save) an image taken by a mobile device to file, the orientation gets messed up and you end up with images that are rotated 90 degrees to either side. This is an issue I am currently having.
Code:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult AvatarEdit(HttpPostedFileBase NewAvatar)
{
//SAVE TO SERVER
string newid = Guid.NewGuid().ToString();
[Code] ....
Would I need to convert originalImage to a file type of HttpPostedFileBase or is there a more elegant way to save the file? I tried reconverting it to a stream and then saving it to file, but I failed miserably.
