How to get file from disk and write it to response?
We have some files on disk, and I want to allow logged users to download them.
I restricted access to them via direct link, so I just need how to get them from disk and give them to users via asp.net application.
Thanks
You can just use Response.TransmitFile method, like this:
protected void SomeButton_Click(object sender, EventArgs e)
{
string fileName = #"D:\somepath\somefile.doc";
Response.TransmitFile(fileName);
}
There is also another method Response.WriteFile. You can read difference between them here

return admin.firestore().collection('Users').doc(id).collection('MyAds').doc(mySubString).collection('photos')

What is the right way to render twig file in Services?
Please take a look at this post, was helpful for me:
http://richsage.co.uk/2011/12/16/rendering-emails-with-twig-in-symfony2/
First, you need to add templating to your service
your_bundle.your_service_name:
class: your_project\your_bundle\Service\your_service
arguments: [#templating]
Then you need to add the templating service to your service constructor
private $templating;
function __construct($templating)
{
$this->templating = $templating;
}
After that you just need to call it in the function that handle the TCPDF rendering
function renderTCPDF()
{
$renderedTemplate = $this->templating->render('your_bundle:template_folder:twig_name', array(your_parameters));
}

I read Microsoft explanation about what is OutputStream Property! but i really don't understand what is this mean! someone can give me more explanation about this?
The OutputStream is mechanism by which you can transmit content to the client in binary form such as files. This contrasts with the Output property which enables text-based content to be sent to the client.
If you look at the MSDN documentation for both properties, you will see the OutputStream is an implementation of System.IO.Stream which enables you to work with objects as a sequence of bytes, which is usually the most efficient way of moving file content around in .NET. Output is an implementation of System.IO.TextWriter.

Here is what is at the top of the view source page in IE... not good User Name and password showing...
Data Source=MySource;Initial Catalog=fdic;Persist Security
Info=True;User ID=username;Password=mypassword;User
Instance=False;Context Connection=False;Pooling=false;Connect
Timeout=4000; Exec usp_SYSTEM_CloseSaleSendEmail_db #id=14888 Invalid
object name 'dbo.vwWorkOrderAll'.
don't display it.... this is not displayed unless you write to it by either Response.Write or maybe setting a label/literal to the value of the connectionstring. ASP.NET or any other platform does not show connectionstring unless you show it yourself. seems like you have an exception not being caught and handled correctly either thus causing this output. you need to catch and handle the exception correctly.

How to use flash.filesystem.FileStream ?
FileStream.as file Where?
The class flash.filesystem.FileStream is only available in Adobe AIR. It is not available in Flash Player in the browser. Furthermore, there is no FileStream.as available to read the source code because it is compiled into the runtime and probably written in a lower-level language like C++.
If you want to open a file in Flash Player in the browser, you should use flash.net.FileReference and call the browse() method to display a file dialog. Once the user selects a file, you'll receive Event.SELECT and you can call the load() method to get a ByteArray of data.
If you are targeting Adobe AIR, then the document Reading and writing files should provide you with all the information you need.
This is an AIR only class, so you have to be compiling to the AIR runtime to get it to work.
