Save file automatically without prompting to save it in web browser

In downloading any PDF Files, we need to click on save as popup window in IE and saving it into a folder.
Now, as an automation project, I want that save as popup window should be automatically clicked and it should save the files in the provided folder.
Kindly help us in C# code.
Many thanks.

I don't know if you can set it through code because its all about browser settings also I don't find any option in IE. However in Google Chrome you can customize your downloads using its setting. Please ask the users of your application to start using Chrome (if possible) and change its downloads setting as per the screen shot given below:

Convert .msg to .pdf programmatically in C#

I've been trying to convert a large batch of .msg files into .pdf. So far, I've been able to leverage the Universal Document Converter and its libraries, but there's an issue: because it's basically a printer, it pops up a small dialogue box in the background between the conversion of each file, momentarily holding up the system.
I need this to be completely set-and-forget, running silently in the background. I have upwards of 3,600 messages to convert at once, and this happens at least weekly.
I've utilized the PDFsharp libraries before, but I'm still really new to them. Is it possible PDFsharp can do this, without the annoying dialogue boxes?
Any help would be greatly appreciated.

Actually in the most recent version of Universal Document Converter it is possible to get rid of that dialogue:
1) open UDC preferences window and go to "Advanced" section
2) Uncheck "Show progress window while processing" feature
3) Go to "Output location" section and check "Use predefined location and file name"
By the way, I advise you to try use FolderMill software. It works by monitoring hot folder. So you just copy source MSG files to the "Hot Folder" FolderMill monitors. And it will automatically convert all incoming files to PDF with no user interaction.

Print command in EPPlus?

I'm using EPPLUS to allow users to download data to Excel.
However, I'd like to add a feature wherein they can just choose to print this data rather than download it. Can we issue a print command from EPPLus?

It is a web app
Ah, so there's the main problem... You know, even if EPPlus had a method for printing, it wouldn't help you, because it would try to trigger a printing dialog on the server-side, but you need to send the file to the client over the internet. So I'm afraid the answer is no, the client surely has to download the file either way to be able to print it.
Furthermore, xlsx can't be that easily opened in the web browser (compared to pdf for instance), so the solution to somehow trigger a printer dialog on the clients pc will be a tiny bit difficult. C# can't trigger anything over the internet with asp.net because of the security problems and I'm not really sure if javascript has enough permissions to open an application for Excel file and start the printing process..
Maybe your solution would be to create a PDF file instead of XLSX, send it to the client as a part of the website/response and use javascript to print the file. PDF can be opened in most browsers nowadays and we have a nice js function printWithDialog(). I believe this doesn't work for xls and it certainly doesn't fulfil your requirement "without download". The client has to have the access to the file before he can print it, you can't overcome this.

Automated copy of selected text in pdf file loaded using web browser control in c#.net

This is what I have done:
I have loaded a pdf file in web browser,
Now I want to select text from that file and paste into a text box.
Can anyone help me?

I'm pretty sure that this is going to be prohibitively difficult, if not impossible, to do.
The browser does not 'run' the PDF, it acts as a host for the PDF application, which ends up sharing it's main window. After that, control of the cursor etc passes to the PDF application and the browser is effectively no longer aware of what happens inside it. If the PDF application being used exposes COM interfaces for manipulating the cursor/text selection (doubtful), then it's possible to script against those interfaces from client script - but you won't be able to actually run any script in that window because the browser is showing a PDF, not a web page.
It might be possible if you hosted the web control on a windows forms application, but even so I wouldn't even know where to start on that one.
If your goal is to extract text from the PDF then you're probably better off pushing it through a .Net PDF library. A quick google on that one will yield you some suitable libraries.

if your pdf file has form elements then the file can be submitted to a url.
check this link.. it might help.
Can a PDF fillable form post itself to an HTTPS URL?

ASP.NET: How to send file from database to printer?

I have an ASP.NET 2.0 (C#) webpage with a link that pulls a blob from a MS SQL database and ouputs it in the appropriat file format, i.e., Word, WordPerfect, PDF.
My users would like to print these files with one click. Right now they have to click the link to open the file, then click the "Print" button within the application that they file opened.
In addition, I would like to send multiple documents to the printer, using one click, if possible.
Thanks.

Do you want to print to a Printer attached to the Server, or attached to the client?
If you want to print on the Client, you won't have much chance. For HTML Content, maybe some JavaScript or Flash could trigger the Print Dialog (not sure), but if it's a File that has to be opened in a third party application (i.e. PDF, DOC, XLS etc.), you're out of luck.
If it's an internal Network, you could possibly create a Desktop Application that is installed on every Client's PC that then triggers the Print.
If it is a Printer Attached to the Server, you can use the standard .net facilities for Printing, although you again may have to work around situations where you are trying to print PDF/DOC/XLS etc., because then you need to use Automation (either COM or something like SendKeys), which will cause you headaches on a Server.
So in Short: Not much you can do with only ASP.net at your disposal.

The closest I've gotten to this is using Javascript:
<body onload="window.print()">
...
</body>
which will pop-up the print dialog when the page loads (see this post for more). If you think about it, you probably won't be able to do much else unless you are on an internal network. How would you like your computer to start printing pop-ups "automatically"?
