Streaming large file uploads to ASP.NET MVC -

-

I'm working for an application, I need to allow the user to upload a very large file - that is Probably many gigabytes - Unfortunately, through our website, ASP.NET MVC appears to load the entire request to load into RAM - not exactly ideal for such an application. Specifically, trying to solve this problem via code: 

  if (request.Method == "POST") {request.ContentLength = clientRequest.InputStream.Length; Var rgbBody = new byte [32768]; (Var requestStream = request.GetRequestStream ()) using {int cbRead; While ((cbRead = clientRequest.InputStream.Read (rgbBody, 0, rgbBody.Length)) gt; {fileStream.Write (rgbBody, 0, cbRead); }}}

The buffer-to-request-in-RAM fails to circumvent the psyche. Is there an easy way to work around this behavior?

It has been found that my initial code was originally correct; Only needed to change 

  request.ContentLength = clientRequest.InputStream.Length;  

  request. Contact lang = clientRequest.ContentLength;

Pre-stream in full request to determine the length of the content; The latter only examines the content-length header, for which only the header is sent in full. This allows IIS to start streaming requests almost immediately, which completely eliminates the original problem.

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

Visual Studio 2005: How to speed up builds when a VSMDI is open? -

-
Using Visual Studio 2005, if I open the test in VSMFI and try to run the tests, then sometimes the projects are ready. However, they run very slow. CPU 99% waste and output window VS Shows things associated with compiling it. Is there any way to fix this? It does not make any sense. It is not necessary to upgrade that we are a viable alternative to those people who have to deal with the legacy code. Did you try to upgrade SP1? I do not know of any specific problem in this area, but this will be the first change I tried to do.

booting ubuntu from usb using virtualbox -

I am trying to install Ubuntu on a USB, the problem is that I do not want to repeat the boot once, I want to keep my windows, but I want to boot Ubuntu using the virtualbox and USB to the Ubuntu Want to use my hard drive, but how? The virtualbox will not recognize USB as a hard drive when installing an ISO In virtualbox, you have to create a virtual hard disk. Make a USB drive and tell the virtual box to install a virtual hard drive that you just created. EDIT: To answer some more questions: In the new Virtual Disk dialog, click the button next to the location field, click on the button Virtual Disk on Flash Drive To access, click the arrow next to Save in the Select File in the window next to Save In, and you can access your flash drive from there. I recommend setting the image to be allocated dynamically, because the size of your flash drive is not available disk space. I name the image, then select that image to install Ubuntu in the Verbill box. The virtualbox will never...
