My situation:
i have a web form to let user export the file. It will prompt a save dialog to let user choose where they want to save the file.
So after user click the Export button, there are 3 things must be done at the same time :
(1) Prompt save dialog
(2) Refresh the Page
(3) Pop up a windows to show the crystal report
I have already done the (1) and (2) but how can i do the (3)?
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();
can we save pdf document without save,view,cancel dialogue box in asp.net..

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.".

I have verified that the file exists. Is there another method for prompting users to save a file to their local machine?
I have two very similar pieces of ASP.NET code that send a file in an HTTP Reponse to the client. They should cause the browser to prompt to save the file. The first one works, the second one doesn't. The HTTP responses as seen in Fiddler are below.
Working:
HTTP/1.1 200 OK
Cache-Control: private
Content-Length: 228108
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Server: Microsoft-IIS/6.0
X-Powered-By: ASP.NET
X-AspNet-Version: 4.0.30319
content-disposition: attachment; filename=Report.xlsx
Date: Wed, 05 Jan 2011 12:17:48 GMT
<binary data>
Not working:
HTTP/1.1 200 OK
Server: ASP.NET Development Server/10.0.0.0
Date: Wed, 05 Jan 2011 12:19:21 GMT
X-AspNet-Version: 4.0.30319
Content-Length: 228080
content-disposition: attachment; filename=report 2.xlsx
Cache-Control: private
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Connection: Close
<binary data>
When the first one is seen in Fiddler the browser correctly prompts to save the file. When the second one is seen in Fiddler, nothing observable happens in the browser. Same behaviour in both chrome and firefox.
EDIT: ASP.NET code that produces the second response
Response.Buffer = false;
Response.ContentType = @"application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AppendHeader("content-length", genstream.Length.ToString());
Response.AppendHeader("Content-Disposition", string.Format("attachment; filename={0}.xlsx", filename));
byte[] buffer = new byte[1024];
genstream.Position = 0;
int n;
while ((n = genstream.Read(buffer, 0, 1024) ) > 0)
{
Response.OutputStream.Write(buffer, 0, n);
}
In a project when user click a button, some data is gotten and written to an excel instance by interop library.
Now, I want that: When excel instance get all data, a save as dialog box muste be open and save this excel instance to user specified path.
Is there a way to do it?

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.
My Asp.Net calls a SQL sproc and returns a XML file as a string. This is what I need to do:
- save that string into memory (as a file);
- pop up a dialog box asking the user which path he would like to save the file;
Any samples out there...how do I achieve this task in Asp.Net C#?
I am using the following code to write the contents of a string (converted to a byte array) to the client in ASP.NET/C#
byte[] data = StrToByteArray(strData);
Response.ClearContent();
Response.AppendHeader("content-length", data.Length.ToString());
Response.ContentType = "text/plain";
Response.AppendHeader("content-Disposition", "attachment;filename=" + fileName);
Response.BinaryWrite(data);
Response.Flush();
fileName is the name of the file ending with the file extension (.pgn). However, the file is saved as a .txt file, ignoring the extension that I am giving it. Would this have to do with the Response.Contenttype = "text/plain"? How can I get the Open/Save dialog to display and save the correct (.pgn) filename?
Also, if filename is a string separated by dashes or spaces, when the Open/Save dialog comes up, the filename is not displayed in its entirety but it is truncated where the first dash (-) or space (or comma) is encountered. How can this be remedied?
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)
which one is better response.redirect or postbackurl(asp:button feture) to redirect web page?
View 3 RepliesI want to redirect to "~/City/Göteborg", but if I just write Response.Redirect("~/City/Göteborg"); I will end up with an ugly URL in the address-bar like this: http://www.mysite.com/City/G%c3%b6teborg..
So my question is how to redirect to obtain a clean url like http://www.mysite.com/City/Göteborg?
I create a window dialog by calling window.showModalDialog;
In that dialog I want to execute a Response.TransmitFile like the code below. The code works fine from a non dialog window. However it just hangs if I call it from the modal dialog page. No error messages. I just doesn't do anything. Is there something else I need to do to get this to function in a dialog window?
string thePath = "c:\temp\New Text Document.txt";
Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AppendHeader("Content-Disposition", "attachment; filename=" + "New Text Document.txt");
Response.TransmitFile(thePath);
Response.End();

Is it necessary to call Response.End() after Response.Redirect(url) Update for all the answers. Because some answers say that it's necessary and others say no, I have searched more and have found in msdn under remarks the following: Redirect calls End which raises a ThreadAbortException exception upon completion.
