With reference to example: [URL]
I downloaded it and worked fine. However, I wish you push it further adding the following features:
1- Download button: where after the bitmap is captured and published into the image control, a "Download" button can be clicked to force the client browser open the "Save As File" dialog box in order to enable the user download the image into his/her client machine after choosing his/her suitable directory path.
2- Email button + Textbox to type the target email: where after te bitmap is captured and published into the image control, a "Email" button can be clicked in order to send the captured image to any email the user had specified in the textbox.
Condition:Â
- Captured image shall remain as bitmap in memory. It shouldn't be saved in the server.
- Email shall be sent with the image placed in the BODY and ATTACHMENT.

I'm currently trying to implement a controller where you can download files from (more specifically jar-archives). The files are stored on disk and not in database. So far I have come up with this:
public FilePathResult GetFile(String fileName)
{
return File(Path.Combine(Server.MapPath("~/App_Data/Bundles"), fileName), "application/java-archive");
}
Nevermind the lack of error handling and such at this time. The file do get downloaded this way, however it gets the wrong name. Instead of, for example, "sample.jar" the file gets the controller's name, "GetFile", (without extension).

We are using asp.net and c#3.5 implementing a website using quite a lot of jQuery. We would like to download an img from the browser window, but (and here's the trick) in a button click (in addition to right click save as)...
Before we get into it, I should state that we know that this is an img tag and from the front end, we can easily download the image using right click save as. The only reason we wish to download the image from a (say) button click is because across the site we have download buttons for downloadable content (like datatable to excel files and pdfs, etc) and we would preferably like to keep the standard across thewebsite.
We are producing graphs using Microsoft Chart Control which renders the graphs to the screen pretty well. This renders an image to the screen as shown below in an example (using Firebug)
<div align="center" style="margin-top: 30px; margin-bottom: 30px;" id="graph">
<img style="border-width: 0px; height: 500px; width: 465px;" alt="Chart Loading" src="/Telma.UI/ChartImg.axd?i=chart_194e3c04c11240a7b7fba3e3e1d76d39_2.jpeg&g=338b984aaab84b1da9a63db3150211e2" borderdashstyle="Solid" id="ctl00_Chart1">
</div>
The img tag is generated from the Chart Control which in the asp is in an <asp:Chart> tag.
Now as an important side note we have in the web.config
<add key="ChartImageHandler" value="storage=session;privateImages=true;timeout=10;deleteAfterServicing=false;WebDevServerUseConfigSettings=true;" />
There is a known bug with MS Chart Control that if you store the image in session variables or memory, that the image is only accessible once and not persisted. Described here
We don't have a physical location for the image when it is created (and most often the Chart Control destorys the image).
What we need is some client side method of downloading this image content from the screen as it is rendered, but without having access to the physical image at the back end. We do not want to use the chart control property:
ImageStorageMode="UseImageLocation"

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.

I'm creating an Excel file in C# on my asp.net web site. Then, I want to save this file somewhere within the web server's files, and send that file to the browser for the user to download. I've got it working on my local system in the dev environment, but I'm not getting the file addressing right. How can I store a file in "~ParentFolderSubFolderfile.ext". Then send that file to the browser for user download.
String outputFile = Utilities.writeToExcelFile("", MapPath(@"~ReportFilesTempFilesDropShipData.xls"), table);
DownloadFile(outputFile);
public void DownloadFile(string fname)
{
string path = fname;
string name = Path.GetFileName(path);
string ext = Path.GetExtension(path);
string type = "";
// set known types based on file extension
if (ext != null)
{
switch (ext.ToLower())
{
case ".htm":
case ".html":
case ".aspx":
case ".asp":
type = "text/HTML";
break;
case ".xls":
case ".xlsx":
case ".csv":
type = "Application/x-msexcel";
break;
case ".pdf":
type = "Application/pdf";
break;
case ".txt":
type = "text/plain";
break;
case ".doc":
case ".docx":
case ".rtf":
type = "Application/msword";
break;
}
}
Response.AppendHeader("content-disposition",
"attachment; filename=" + name);
if (type != "")
Response.ContentType = type;
Response.WriteFile(path);
Response.End();
}
Again, this works fine on my local pc, but when I move it to the server I get an error for accessing the path. And the path listed in the error code is NOT where I want the file to go.

I've to download files from our 38 clients secure websites. They are our data resources. Currently data collection process is manual. Logon to the site, login with username and password, then download files, save to local folder, close window once download is completed. We are trying to automate download process. Plan is to handle login part with code and directly show list of filename to User with check box , so User can select files and click to save.
Rest all will be handled programtically. Once download is complete the status for that file will change to "Saved" or "Download Complete. I'm working on Window 7, VS2008(C# asp.net). Trying to make it work with WebClient class. It'll be great if you can post some source code or guide me to link or post for solution.

This should be pretty simple but I don't work on my website code too often so I thought I would ask about this. I have a download link for an application of mine on my website and I wanted to keep track of how many downloads are taking place so I want to create a counter. I added a table to the SQL database I already have on my website with the columns Downloads and CountID which is listed in the column properties as identity specification. At first I just had the column Downloads but when doing a query I was having problems so I added CountID and that made the query easy to do.
When the link on the download page on my website is clicked I wanted Downloads to increment by 1 each time. I used Visual Web Developer to build my site. Should I use a Web Method to increment that or is there a more direct method. I also noticed when I'm working in Visual Web Developer and I have the designer open for a webpage that in the toolbox items you have table and the icon looks the same as a table for an SQL Database. Should I perhaps use that? Add a table to this webpage and work with that?

I am trying to implement a service to download a image file. The code does nothing but upload a file to the response with each client request.
There are no SOAP messages involved but I am planning to implement it as ASP.NET web service. It can also be implement as ASP.NET website but since it has no view (forms, html etc) I planned to implement a web-service.

I have created an ashx handler to render image thumbnails from images in a mysql database. If a file name is passed through querystring, the content disposition filename is set (when user clicks "save as..." the filename appears). The images appear properly and the filename appears when user selects "save as..." but the filetype is listed as unknown and the file that downloads has no type. I have tried adding ".jpg" to the end of the filename in content disposition for lack of anything else to try, but this made every image download as untitled.bmp.

I am planning to sell digital goods on my website (Asp.net). After successful payment the customer will be redirected to the download page of my website, which will display the link to download the digital content stored in my server.
I want to secure the location of the file, by creating a disposable link to the file. Every time a customer visits this page a new download link will be generated for the same file. Also this link should expire after it is downloaded for the first time.
Is it possible to do it in asp.net ( C# preferably )? if yes how can i do it?
