Web Forms :: HTTPHandler And Posted Files - Prompt A User To Crop Photos After Save
Mar 18, 2010
I am building an application that allows a user to upload multiple images, resizes them, and saves them. What I need (ok, what I'd like) is the following...
I would like some sort of way to prompt a user to crop the photos after they have been saved. I have code that creates a 175px square rectangle and saves that image. I need the user to select the image section they want saved and to do so I envision a window that automatically prompts them to do so once the upload(s) have completed. I think my preference would be to have a page or control (datalist, repeater, ectc..) that refreshes every time an image is saved and allows the user to crop the newly saved images. I'm opened to advice, opinions, free drinks and a clue.
I'm trying to write code that will allow a user to click a button and be prompted to save an image file that resides on the web server. I'm using the following code, but I get an error that says "Error: Could not complete the operation due to error c00ce514.".
[Code]....
I have verified that the file exists. Is there another method for prompting users to save a file to their local machine?
A friend of mine gave me this task so I can learn advance programming a little bit easier. I am currently doing convertion of an html page to pdf using itext sharp and email the pdf as an attachement. My idea is to save the pdf first to the server machine in the folder name ToBeEmailedPDF folder before using it as an email attachment. The thing that bothers me is that this dialog as what you can see in the picture shows up using the code that I have below.
i wan code for profile image setting. user can able to resize image by selecting size in the dropbox. and image cand drag specific location,(canvas image-->image can bigger then canvas and he can drag image withini the canvas,image shoud save--withini the canvas width and height)
Rquirements
1)user upload the image and will save that image and will disply the image at left side show in the figure. 2) user can select the size of the image from dropbox. the image size will be alter depend upon the selected size. 3)user can drag the image in the specific location. i mean selecting image with mouse can drag, shoud be dragable. 4)same as profile image setting of gmail,facebook and skype.
I am using a third party applet which enables a user to paste a screen shot into it and it posts the file data to an upload page. I am pretty new to asp.net (VB) and wondered if I could use a Generic Handler to read the post data and save the file to disk or just a normal web form to do this? All the examples I have received with the applet are in php of which i have had no experience coming from a Classic ASP background.
I am using asp.net and I need to display a prompt to the user if they have made changes to the web page, and they accidentally close down the browser.
The page could be anything from "Edit Profile" to a "Submit a Claim" etc.
How can I can display the messagebox, ensuring that it is displayed only if changes have been made (as opposed to, the user making changes, then undo-ing the changes, and shutting down the browser)
Currently I have the text file going to desktop, in ASP how can I prompt a file save dialog for the user? The result is string from the streamreader as "result" as follows:
StreamWriter FileWriter = new StreamWriter(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "file.txt")); FileWriter.Write(result); FileWriter.Close();
I have an ASP.NET file upload control which sits as part of a form. The file upload control is on the content page while the form definition is on a master page across the site. I've added multipart/form-enc to the form on the master page.I'm using jQuery to submit the form as I show a dialog box from jQuery UI.When I post, no file is returned to the server. The file upload control has no file and HttpFileCollection is empty.
I just inherited an ASP.NET WebForms web application that I was tasked with refactoring. One of the features is a file upload and while debugging I noticed that as soon as a file is posted to a certain page/handler, it is automatically uploaded to the root directory of the application. The file is then moved to the proper location. I can't seem to figure out whats causing this automatic upload of the file. Is there something I'am overlooking in ASP.NET WebForms that allows this to happen? Is it an IIS configuration or something?
I am using uploadify for a photography site I am building. I have an HTTPHandler that I'm using to save the posted file. What I am wondering is if I can resize images, insert a record of the image into a db and save the image from the HTTPHandler? This is my first experience with HTTPHandlers so forgive me if there is an obivious answer for this.
I created a HttpHandler for downloading files from the server. It seems it is not handling anything...I put a breakpoint in the ProcessRequest, it never goes there.
public class DownloadHandler : IHttpHandler { public void ProcessRequest(HttpContext context) { //download stuff and break point } }
It never stops there, as mentioned. I also registered it in the web.config.
I am not sure about the path part of that entry. What do I have to enter there? I am downloading txt files, but the URL does not contain the filename, I somehow have to pass it to the handler. How would I do this? Session maybe?
I had a look through some of the older questions, but I can't find anything.I have a Wildcard HttpHandler on my web app which is processing the url and working out if it can do anything with itIf it can't, then the StaticFile Handler should pick it up and just serve it as a static file (like an html file).The problem is, it's going through the Wildcard handler, then seemingly not going to the StaticFileHander. Is there something I need to do to the Wildcard handler, or in the web config?This is my web.config:
I need to access image files (.jpg) on a server other than the web server my app runs on. I would like to use an httphandler to do this but I am unsure of the syntax to specify the path. I have tried mapping a drive on the web server to the file server but that didn't work. I have tried using a UNC path but that did not work either.
When inserting, i would like to check if the record exists in the table, then if it doesn't, insert it, else either redirecting to a different page, or showing a message box saying "Record already exists" ...
Does anyone know how this is possible? I can retrieve the file, but I cannot figure out or find anywhere online how to prompt the user where he/she wants to download the file to.
I have a problem with large respones and IIS7, the server runs out of memory. I've written the test code below that works pretty much like my real code... When i start to download the file i can se the memory usage rise until it hits 100% and Firefox complaints about lost connection to server, looks like IIS7 does not release cache or something.. Works in IIS6 by the way
I have to warn the user when leaving the gridview row in edit mode without saving or cancelling the data. How can I achieve this? I have a javascript function which simply prompts the user when he/she leaves the screen which is not serving the purpose.
