Native vs ODBC database connections with R -

-

I understand that some databases have basic support in R (like MySQL), but you connect to other DBSs like MS SQL Server can do. RODBC. How much speed improvement is there a benefit to reading / writing with native drivers versus RODBC? Are the other DB's native drivers in R? Reading faster or faster than writing at all?

If you are interested specifically in SQL Server, the reference is slightly older but I It seems that it probably still holds.

ODBC's performance as an original API

The constant rumor about ODBC is that it is more natural than the original DBMS API This argument is based on the assumption that the ODBC drivers should be implemented as an additional layer on the native DBMS API, the translation of the ODBC statements coming from the application translates to the native DBMS API functions and SQL V In Yvinyas. This translation effort adds additional processing directly to the original API than the application call. This assumption is true for some Odyssey drivers applied to a native DBMS API, but the Microsoft SQL Server ODBC driver has not been implemented in this way.

The Microsoft SQL Server ODBC Driver is a functional replacement of the DB-Library. The SQL Server ODBC driver works with the built-in net-libraries in the same way with the DB-Library DLL. The Microsoft SQL Server ODBC Driver has no dependencies on the DB-Library DLL, and if the DB-Library is not even on the client, then the driver will work properly.

Microsoft's testing has shown that the performance of ODBC-based and DB-Library-based SQL Server applications is almost equivalent.

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...
