It 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.

I'm having an image in my page displayed to clients form a folder under same apllication folder,I also have a form in the same page that accepts an image file to be uploaded. The image that is uploaded via this form should take the place of the image that's displayed in the page with the name newly givven at runtime. The new image should be uploaded in the same directory with the new name provided, which means it overwrites the previous image.

View 5 RepliesI am developing a web based application for a Motorolla Mc 9090, it is a wireless barcode scanner running windows mobile 5.0.
The idea is to centralize the inventory in one database, by scanning items, serials, bins etc.
I have a set of pages each containg forms, where the user will have to scan an item, and automaticall the scanner has a carriege return (ENTER key) the idea was to have the user simply scan, and the page would automatically click the button posting to server for processing and then the server would reply.
For some reason i cannot get the focus() to work as well as the defaultbutton propperty of the form. There is also 1 more problem, the readOnly textboxes look the same as the non readOnly textboxes, even with the backcolor property changed.(guessing this is just MS)

View 2 RepliesI'm currently developing a web application in asp.net 3.5 that will be accessed by windows mobile internet explorer on Windows Mobile 5. I'm using access for the backend (Yes, I know MS SQL would be a better option). The problem is that I'm receiving inconsistent query results between my test server and the when I access the application on IIS. I have a page that will scan a number and update the db on that number(which is stored as text in the database). This works on my test server but when I try it on my web server from my machine or someone else's mobile device, i will get a "No value given for one or more required parameters." But this is the same query that works on my test server! I don't get it, I've even tried to upgrade Windows Mobile 5.0 to Windows Mobile 6.0, with no success. Can someone give more insight into this issue?
View 6 RepliesI have to insert default image into databse..when no image is selected from fileupload control.. Here is code...not working for default image...
if (FileUpload1.HasFile){string FileName = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName);
FileUpload1.SaveAs(Server.MapPath("~/UPLOADEDFILES/" + FileName));
feedBack.Attachments.Add(new Attachment(FileUpload1.PostedFile.InputStream, FileName));
} else {
string filename="~/images/"+ "sun.gif";filename.pPropertyImage = filename;FileUpload1.SaveAs(MapPath(filename));}
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.
View 1 RepliesI'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).
