I have code that is successfully uploading images to a folder on my website with the code below.. what I would need to do next to actually display that image on the same .aspx just after the actual upload?
Private
Sub btnUpload_Click(ByVal sender
As
Object, _ByVal e
As System.EventArgs)
Handles btnUpload.Click
Dim destDir
As
String = Server.MapPath("./images/Upload")
Dim fName
As
String = Path.GetFileName(uplPicture.PostedFile.FileName)
Dim destPath
As
String = Path.Combine(destDir, fName)True
lblUploadSuccessful.Text = "Upload succeeded."
End
Sub
I have the following code that is allowing me to save an image uploaded from a user into a root folder
HTML Code: Protected Sub Button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Button1.Click Dim fileName As String = Path.GetFileName(FileUploadUserProfile.PostedFile.FileName) FileUploadUserProfile.PostedFile.SaveAs((Server.MapPath("~/ImageStorage/") + fileName)) Response.Redirect(Request.Url.AbsoluteUri) End Sub
Question one: Once i upload the file and i click on the ImageStorage folder, i don't see an image, but if i exit the entire applicxation and then i go back in i am able to see the image. How can i refresh the folder wothout having to exit the application?
I am trying to display the image once is uploaded. i have the following to display the image:
HTML Code: <img src="string url = ResolveUrl("~/ImageStorage/" + filename)" />
Occe the page is uploaded i don't see an image, instead i see a little square with a red X
i did this code to upload file and displaying it in the image:
[Code]....
the code works good. the file is uploaded under my website here in the solution explorer: now after uploading the file,the newly uploaded file is shown in the image(since there were a few more images present in the same location but they were not shown by the image) i used this url to the imageurl:
ResolveUrl("~")
which returns me this:
WebSite1
now my question is why the newly uploaded image is shown in the image? there were several other images present at the same location and even i have not used something in my code that tells to show only the newly added image from my website into the image.

I've got to following function which is called to change the resolution of an image. I want to do this so uploaded image with for example 300dpi will be modified to 72dpi (for web). This question is related to another question here on SO where i'm working on.
I'm creation an extension method for this to be able to use this function on more places in my application, instead of only when uploading new files. (See above mentioned question)
public static byte[] SetDpiTo72(this byte[] imageToFit, string mimeType, Size newSize) { using (MemoryStream memoryStream = new MemoryStream(), newMemoryStream = new MemoryStream()) { memoryStream.Write(imageToFit, 0, imageToFit.Length);

Does anyone know how to display the uploaded image onto the webpage after the image has been uploaded via the asyncfileupload control?
I tried setting the value of an imageurl property of an image control within the OnUploadComplete event however it seems the code 1st refreshes the page, runs through the Page_Load event, then finally the OnUploadComplete, so I'm assuming since it's run last, this is why it doesn't display the imageurl.
I have an asyncfileupload control. AFTER the file has been successfully saved to disk I want to assign the uploaded image to a HTML element. To show it to the user.
Important: in the afuFlyer_UploadedComplete method I'm renaming the image, so the image saved to disk does NOT have the same name as the file the user initially uploaded.
function Async_UploadComplete(sender, args) { var filename = args.get_fileName(); var contentType = args.get_contentType(); var text = "Size of " + filename + " is " + args.get_length() + " bytes"; document.getElementById('lblStatus').innerText = text; }
But the args.get_fileName(); is useless since the filename has been changed. So I need to pass the new filename to this method somehow? Also, is the image actually already saved to disk when the Async_UploadComplete function is called? Or has the upload to the server just been completed and not the saving to server disk?
Ive also tried working with ScriptManager.RegisterClientScriptBlock and ScriptManager.RegisterStartupScript in afuFlyer_UploadedComplete method without success:
I have ASP.NET form with an upload control for users to post an image. On the server I load that image (using the Bitmap class) and resize it. Is there any danger in doing that when users upload malicious or affected files or will the code just throw an exception at some point and stop the whole process?

How to add watermark to uploaded doc (pdf or image files).The workflow will be-User register at portal -> user upload some required document (like financial proof or some kind) -> When saving them to database -> a watermark (predefined by admin at backend in admin panel as - Logo or Text) will be added to those uploaded document on top and bottom or wherever possible on the uploaded document.
So in future when admin views the document uploaded by him in his account, it will be displayed with stamp or the watermark. It will prove that the document is uploaded to server by user or whatever. Now, this we have found way to do in jpg, but in case of pdf its quite tough..
I am working on a website, using C# with a SQL backend. I'm using the Varbinary data type to store my images because the Image data type is eventually going away. I got the images into the DB and can pull them back out to display on the website. My question is how can I put the images from the DB into an Image control on the website? The images will be different sizes, so I need to keep them confined in one space on the site. I also need to randomly display the images, one at a time, on the website. The user needs to be able to hit the Next button to see the next image when they are ready. The user will only view the images, not make any changes and send data back to the DB.
Since the image will be confined within the image control, how can I allow the user to click on the image and open in a new window? The image needs to be bigger to allow the user to see more detail. Or would it be easier to allow the user to zoom in on the image within the current window?I am using VWD Express, C# 2010 Express & SQL 2005 Express.
