sql server 2008 - Need help trying to RANK with a GROUP BY -

-

I am having difficulty in ranking each of my students in the house group, which they are inside.

Example counterfeit data 

  HomeGroup 1. Team Red 2. Team Blue 3. Team Skeet 4. Team Green Students 1. John, Score - 34, Team Red 2. Jill, Score - 87.3 Team Red 3. Fred , Score - 41, Team Green 4. Jane, Score 93, Team Blue ...

etc.

My Production Low 

  Score student 1, score 34, rank - 5th student rectangle 2, score 87.3, rank - 1 student id 3, score 41, rank - 9th student 4, score 94, rank-1

I'm trying to use DENSE_RANK .. And if I run against a single homegroup (for example Homegroup = 1) then it works fine ... But I'm not sure how to do this on all HomeGroup.

I'm guessing that I need an update query, which has a subquery ... and this subquery has its own subquery ... ??

I am very confused :( And I think of the evil cursor that I refuse to use until I get a gun on my head (because I believe this' set 'Notation can be handled correctly).

Obtaining dense_rank of each student in the team To: 

  SELECT *, DENSE_RANK () (part of the team by the team order by the score);

It is not clear to me that Do you want to update.

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...

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...
