asp.net mvc - How can I use nHibernate to get a small subset of object properties for list view -

-

I am using ASP.NET MVC and nHibernate for the first time. Great tool, but the big learning curve!

I have a list view of such items which are large (each has about 60 properties). In the list view, I'm only using these 10 properties. Performance is not very bad, but it seems wasted to completely hydrate these objects. What is the recommended exercise?

I tried to use HQL to select fewer properties, but it seems that it will not partially hydrate an object. I also tried to create an asset on the main object, which was a header class with list view properties, but I think it can not be mapped properly. I think it should be easy, but I'm really struggling with it.

Edit: I was coming back to this because I knew that Anton had given me a reply and I just could not see it.

  1. Make an object with the property you want.

  2. Import this object to create a mapping file.

    & lt; Hibernate-mapping xmlns = "vase: nibinet-mapping -2.2" namespace = "core.nitties" assembly = "core" default-access = / & lt; / hibernate-mapping> & lt; import class = "request header" / & gt;

  3. If you are using HQL, then a constructor with all the properties in your object should have a new statement in the same order as your selection. . If you use the Criteria API, you do not need to do this. 

      Public IList & lt; RequestHeader & gt; ListAll () (usage (eSession session = GetSession ()) ({ITRansaction tx = session.BeginTransaction ()) {IList & lt; RequestHeader & gt; Result = session Prepare calculations (typef (request), "R"). CreateArtia ("Requestor", "Rick", Joint Type.Inrzoyan). Cretecritia ("R. Grant", "Jee", Joint Type.Inrogen) .Setprojection projection. Projection List () Add (Projection Property ("RID"), "ID"). Add (Projection Property ("R. Status"), "Status"). Add (Projection Property ("R" properties ("g.Number"), "number")) .Setet Transformers (Transactions) (Projections ("req.Name"), "Requestor") Add. .AliasToBean (typeof (RequestHeader)) .SetMaxResults (10000) .List & lt; RequestHeader & gt; (); tx.Commit (); Return Results;}}}

See 60 properties are too high.

To select a subset of properties , See: you have a choose new to build the HQL The Shykta is. Keep in mind, though, you need an appropriate constructor and objects can not be saved if you get it back dB.

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

PHP - get image from byte array -

I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
