What is the data type of "select 123.866" in SQL server 2005? -

-

If I just write something 

  choose 10.00;

How does it bring me?

Here is a test that I went to, to test the binary representation of these types. The surprising thing here is that does not really match the first line in any armor! Select cast (as 123.866 binary) Union All selected artists (cast (123.866 real) as binary) All selected artists (float as cast (123.866) Association as binary) All selected artists (as binary in the form of Cast (123.866 decimals) Union All selected artists (cast (numerical as 123.866) binary as union) All selected artists (cast (123.866 Form of money) form of binary In) union branch select all (cast (as 123.866 smallmoney) in binary form) -------------- 0x0000000000000000000000000000000000000000000006030001DAE30100 0x000000000000000000000000000000000000000000000000000042F7BB64 0x00000000000000000000000000000000000000000000405EF76C8B439581 0x00000000000000000000000000000000000000000000120000017C000000 0x00000000000000000000000000000000000000000000120000017C000000 0x00000000000000000000000000000000000000000000000000000012E684 0x00000000000000000000000000000000000000000000000000000012E684

Can anyone explain this?

Basically, to avoid writing all the cast studios I wanted to do, assuming 123.866 meant a decimals. So I thought to test whether these two statements were the same: 

  Choose cast (123.866 as decimal) 123.866 Select
< P>

It is basically typed as decimal (6,3) - cast it over and you get binary values. It seems that to use the decimal number after decimal after decimal, in the smallest tape to fit the value - in this case, 6 digits.

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.

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...
