c++ - MATLAB MEX interface to a class object with multiple functions -

-

I am using the MEX interface to run the C ++ code in MATLAB. I would like to add many functions to MATLAB for dealing with sysSetAttribute (name, value) string = sysGetAttribute (value) to system object: 

  sysInit () sysRefresh Each MEX DLL can include a function, so I need to find a way to store the indicator in the global  system  object, which will remain in existence until it will not be removed  sysExit < / Code> by calling. 
 
 How can I do this correctly in MATLAB? Are there any ways to call Global Porter to call in MEX work?

A common way is to provide m-file functions that provide a public interface, such as SysInit.m, sysRefresh .m, etc.

Each of these M-Fixes identifies the function to call the Mexico function with any type of handle, a string (or number), and any additional aggregates for example, sysRefresh. M can look like this: 

  function sysRefresh (handles) reverse systemmax (handles, 'refresh')

In your sysMex mex function, you can Either a raw pile indicator might be (easy but not very secure), or you can use C / Maintain mapping in C ++ with the handle ID for the real object pointer. This solution requires a little extra work, but it is very safe, in such a way, by mistake, one can not give an arbitrary number as a handle, which acts as a drop indicator. Also, you can work like fancy things like using the on-Kleinop function to release all memory and resources while unloading Mac Function (for example, when you re-compiling Mac fax, restart the mailbox. Do not need to be)

If you want you can go a little further and hide handles behind the matlab class. If you are interested, then read the OO features for Matlab in the dots. If you are using the latest version, you can take advantage of their very cleaner handles object.

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...
