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!

when the file file1 has been changed or removed. How can I do one refresh to the item to make it reflect the recent change?
I have a problem about image control. I am using VS2005 in Vista and suddenly uploading and retrieving image to a image control doest not work. I am working with this in Windows XP and all goes fine. After transfering it to vista, I can't upload and retrieve an image stored in the File System. My codes are all the same.
View 19 RepliesIn my asp.net project, I have a view－image page and an upload－image page. I upload an new image and direct to the view page, the image doesn't be changed, because IE won't reload the image if the image's url remains the same. prefer the way to ask the browser to reload the image independently without server setting or web-headers changes.

ProductImages is folder where i am saving image. Can anyone find why this is giving error,my code is
string strBigServerPath = AppHardcodeValue.productImgPath;
string strFileName = "";
if (prodImg.HasFile)
{
strFileName = prodImg.PostedFile.FileName;
string uniqueNum = Convert.ToString(System.Guid.NewGuid());
string shortFileName = System.IO.Path.GetFileName(strFileName);
string Extension = System.IO.Path.GetExtension(prodImg.FileName);
string newFileName = shortFileName;
prodImg.SaveAs(Server.MapPath(strBigServerPath + newFileName));
using (System.Drawing.Image Img =
System.Drawing.Image.FromFile(Server.MapPath(strBigServerPath) + newFileName))

i want to upload image through folder looping.
code is for that
DirectoryInfo di =new DirectoryInfo ("G:/FICCI/FicciNew/FicciNew/images/Images/AlbumImage");
in my application i am uploading the image into database. before it is store in the database, i want to do image management like decreasing size and decreasing height and width of the image.
View 4 RepliesI am able to upload an image to a Database from a fileupload control on a detailsview inserting event and then display it again. Here is my code to upload an image from a fileupload control:
Dim UploadedFile2 As FileUpload = CType(DetailsView1.FindControl("Fileupload2"), FileUpload)
Dim extension2 As String = Path.GetExtension(UploadedFile2.PostedFile.FileName).ToLower()
I've got a working update panel which works fine when updating a label control, but I can't get it to work with an updated image (initial image loads fine - the problem is with the update). I think the problem maybe that the image name and location don't change, only the physical file. In other words, I've loaded the page, then updated the image (same name and location), but the image does not update with the label? Here's my code:

And the code behind:

I've taken over work for the custom forums that a previous developer created at my job, and came across a minor bug. We don't allow animated GIFs as avatars in the forums. However, if someone were to take an animated GIF, rename it to imagename.jpeg, and then upload it, the forums will show the image as being animated.
It's a very odd bug as I didn't even think it played the animation if the extension wasn't .gif.
So my question is: Is there a way to check (in .NET 2.0) if an image is an animated gif, even if the extension isn't?
i use this code to display my image from database

How can we add any wait image or progress bar when we upload a big size file to upload and it take several minutes to upload a file.
I want to show any Image or progress bar.
look at the picture, i want that image preview will come when i choose the file location before uploading to the database. is it possible?
EDIT: i found codes in other sites, they say those only work in IE, so it means currently, this preview function doesnt support FF? coz im using FF or sometimes google chrome.
I'am Developing a commercial website using vs2005 and sql 2005,where my users will download and upload wallpapers and ringtones,so my issue is, i got the coding for uploading ,
But the problem is it is storing the files two times,

Dim FileName As String = System.IO.Path.GetFileName(FileUpload1.PostedFile.FileName)
FileUpload1.SaveAs(Server.MapPath("Images/" & FileName))

I'm trying to craete an upload form using the following code:
[Code]....
when I click the 'Add imag' button I keep getting this error:String or binary data would be truncated.
The statement has been terminated.the 'Image' column in the SQL database is set to VARBINARY(250) and this exception still pops up even when I'm trying to upload a small 3kb JPG image, why is that?
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.
Is there any controls that I can download that allows a user to upload images with just a button click and be able to open the file dialog. I do not want to use the fileupload control.
View 2 RepliesThis is the first time I've come across this kind of problem before and I'm having trouble approaching it.
I have a swf developed by someone else that posts an image and I have to create a handler of some kind to capture it, name it, then upload it to a directory. I've tried a couple ways and nothing is working.
this is a quick an dirty approach, just an aspx file
<%@ Page Language="C#" %>
<%@ Import Namespace="Components" %>
<%@ Import Namespace="System.IO" %>
<script runat="server">
public partial class upload : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
string uploadDirectory;
uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];
imageFile.SaveAs(uploadPath);
}
}
</script>
this is another approach using a handler.
<%@ WebHandler Language="C#" %>
using System.IO;
using System.Web;
using System.Web.Configuration;
using System.Web.IHttpHandler;
public class Uploader : IHttpHandler.i
{
public void ProcessRequest( HttpContext _context )
{
string uploadDirectory;
uploadDirectory = Path.Combine(_context.Request.PhysicalApplicationPath, @"images");
//uploadDirectory = Server.MapPath(@"images/");
string imageName = "image.jpg";
string uploadPath = uploadDirectory + imageName;
//FileUpload imageUpload = new FileUpload();
// Get the data from the POST array
string Email = _context.Request["email"];
HttpPostedFile imageFile = _context.Request.Files["image"];
imageFile.SaveAs(uploadPath);
}
}
I am looking for a solution (APIs, etc.) for handling a similar experience as cafepress.com. I need to be able to upload images (preferably multiple at a time) and be able to map my uploaded images to various product images (clean stock images of shirts, mugs, etc.). I also want to give the user some very basic controls over the images they upload such as cropping, resizing, levels, etc. I am looking for .NET solutions (if server-side).
