Q.1. When a image file is uploaded via AjaxUplaoder of CuteWebUI.Uploader it saves file like this
persisted.057fe17e-9707-4f3a-91b7-250239b19c2f.10.JPG.resx
in which "10.jpg" is Image file name and Other "persisted.057fe17e-9707-4f3a-91b7-250239b19c2f.10.JPG.resx" I dont know what is this?
Kindly help me to extract file name from this given format "persisted.057fe17e-9707-4f3a-91b7-250239b19c2f.10.JPG.resx" so that I can show image on Image Control of ASP.Net that is uploaded image file via this Ajax Uploader. This ajax uploader's property 'args.filename' gives file name on 'FileUploaded' event.

Folder_Code with Visual Studio 2010 and Code Load Image:
Code Visual
Folder on PC containing CODE :
Folder on PC contain Image save
SQL FilePath and DataFile ( Byte ):
SQL FilePath and DataFile
But, when running the code displayed on GridView and Image Control:
Display GridView
Display Image Cotrol
help me, explain why there are no pictures in the folder but still display pictures on GridView and ImageControl
From what we can see, it looks like the images used are saved in the database, and thus the "folder" is not being used. While the sql data table DID save the path name, it looks like that was for some other "unknown" reason, and that sql table looks to have saved the image in the database, and thus it does not use and ignores the path name used, but in fact the GV code must have a row data bound event, and in that event, the picture is pulled from the database and that is the image used in the GV.
So far? yes, it looks like images were/are/being stored and saved in the database, and the path name column in the database is not being used anymore.
I have a classic ASP question.
I need to show images on my webpage.
But because of the security reasons, I cannot simply put all of my images in the images folder in my website folder and I need to put them outside of my website folder.
For example, my website folder is located at:
C:\Inetpub\wwwroot\mysite\
But I need to put images (which I want to show on my web pages) at:
C:\images\
I am trying to use ADODB.stream object to pull the images using ASP vb codes as shown below:
<%
Response.ContentType = "image/png"
Set adoStream = Server.CreateObject("ADODB.Stream")
adoStream.Open
adoStream.Type = 1
FPath = "C:\images\1.png"
adoStream.LoadFromFile FPath
Response.BinaryWrite adoStream.Read
adoStream.Close
Set adoStream = Nothing
Response.End
%>
When I launch this webpage in internet explorer, the page shows a File Download window/message for downloading the image file "1.png" rather than displaying the image on the web page.
How can I fix the code to show the image on the web page rather than downloading the image file?
That code generates an image as the return type, so there is no HTML to display the image in, if you call this code directly say it's called image.asp then you would do something like this in another page that displays HTML.
<img src="image.asp" />
This will call your code and output the raw image binary as this is what <img> expects.
If you want to produce multiple images from the file system or database pass a querystring parameter such as ?id=yourimage and change the code to select different images.
I currently have a pdf that contains imagefields.
The issue however is that we want to be able to copy the images users input into the pdf.
Is there a way to alter the imagefield or add a button to the form that will copy the image so it will be available for pasting?
I see that I can put a button on the page and via script access the value for ImageField1.value so I can set it. But how can I read it?
you can access the image data by ".rawValue" attribute.
For example with a button and "click" event.
FormCalc: $.parent.sPic.rawValue = $.parent.dPic.rawValue
JavScript: xfa.resolveNode("sPic").rawValue = xfa.resolveNode("dPic").rawValue
with dPic being imagefield and sPic being image. This script will copy the image from imagefield into the image.
In web application, i am trying to display image in .aspx page, for that i write code like this in page_load event ,
Image1.ImageUrl = #"C:\Users\Public\Pictures\Sample Pictures\Koala.JPEG";
but image is not displaying, can you help me thank you.
there is problem with the path of image ...you need to give relative path for image rather than physical path
something like this
Image1.ImageUrl="~/Images/Bird1.jpg"
here image is in the Images folder of the application. i.e.which is part of project
First create a Images folder in your Solution Explorer. Then store your image in that folder and refer like as below.
Example
<asp:Image ID="Image1" runat="server" ImageUrl="~/Images/Bird1.jpg" />
Check in deatil : Image Control Example
You cannot use your local path as the path to your image, instead place the web site url with a relative path to the image
I am using asp.net 3.5 and C#.
I have a image which I want user can download.
Like, there would be a download button or link. When user click on this link he will be prompted with a pop up to save that image to his desktop.
I have tried with
<a href ="path" > </a>
but it is opening the image in other page, I want user to be prompted to either save or view the image,
please help
Thanks in advance
You need to write an IHttpHandler that serves the image along with a Content-Disposition header.
For example:
Response.AppendHeader("Content-Disposition", "attachment; filename=\"MyImage.png\"");
Response.TransmitFile(path);
You would probably pass the image name on the query-string.
If so, make sure it doesn't contain / or \, or attackers will be able to read arbitrary files.
You need to have another page or, better yet, an HttpHandler, that takes the image path as part of the query string or as a post parameter that will send the response with Content-Disposition set to attachment. Setting the content disposition this way will cause the browser to display the file download dialog. A slightly easier way, though it depends on the user doing something extra is simply to have the link open the image in a new page and let the user right-click on it and do a "Save As".
Download
or
<a href="/path/to/image" target="_blank">
Load Image in New Window then Use Save As</a>
