c# - Retrieve single Entity Framework entities using a LINQ query or GetObjectKey? -

-

It seems that GetObjectKey has the advantage of searching for an existing, instant object, and then store data. However, it also seems that you lose some strong typing, and your resultant object is required to be inserted:

GetObjectKey 

  int customerID = 1; EntityKey key = New EntityKey ("MyEntities.Customers", "CustomerID", customerID); Customer Customer = Reference Gate Objectbike (key) as a customer;

vs. LINQ 

  Integer Customer ID = 1; Customer customer = (In the context of C-customers, select c.CustomerID = customerID c). Before and after default ();

Personally, I like the latter method due to typing.

What do you use boys and girls?

In addition, your DAL is the only commonality in conjunction with all available methods, though this is a personal preference.

I like the latter because it is clearly clear what you want. By using EntityKey (and it is something that the ADO .Net team does not understand), we have to work around the structure we imposed by the organization framework. Using the query language you have done in the second example, we are telling the rest of the developers who will ever see our code, we want this object from this ID or we want it to be empty. / P>

I do not think that being right (as you are in the first example) is an excuse not to explain to your colleagues. :)

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
