java - Why does Eclipse compile this, but javac doesn't? -

-

We have some unit tests that run in compilation and precisely Eclipse 3.4, but when we compile them using Java If you try, it fails. I have managed to cut code in some small and self-sufficient, so there is no external dependency in it. The code itself does not understand much because it is out of context, but it does not matter - I need to know this That's why Javak does not like it: 

  public class test {public zero test} (matchon (with some michur (.) (Another mile ()); } Zero MatchOn (Submachter Matter) {} Submachore Some Much () {Return New Submeter ()}} Matcher Another Matter () {Return Tap; }} Interface Matcher & lt; U, T & gt; {} Class Besamacher applies to Maitre {Mater & Lt;?,? & Gt; matte} with the public spat (back); }} The square submeter increases the bettemperature {@ with override public submeter (matter mitchure)) this return; }}

I have tried JDK 1.5.0_10 and 1.6.0_13 , with the same result:

< Pre> test.java:6: Matches in the examination (test. Test can not be tested (test.BaseMatcher) with matchOn (some michaure (.) (Another mile ()); ^ 1 error

I think this is completely valid, the SubMatcher.with () method gives more specific types than BaseMatcher.with (), but the compiler feels that the return type Is basseterter However, it is possible that the eclipse compiler is not allowing it incorrectly.

Any thoughts?

You need to specify the type of parameters in the basmeter: 

  {{Code>  
 Javac with your  method  
 
 with public sub-mother (Matcher & lt;?,? & Gt; 
 
 To allow matches 
 
 There is a bug in the Imho Eclipse compiler

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...
