  • The Collatz Sequence problem

    - by Gandalf StormCrow
    I'm trying to solve this problem, its not a homework question, its just code I'm submitting to uva.onlinejudge.org so I can learn better java trough examples. Here is the problem sample input : 3 100 34 100 75 250 27 2147483647 101 304 101 303 -1 -1 Here is simple output : Case 1: A = 3, limit = 100, number of terms = 8 Case 2: A = 34, limit = 100, number of terms = 14 Case 3: A = 75, limit = 250, number of terms = 3 Case 4: A = 27, limit = 2147483647, number of terms = 112 Case 5: A = 101, limit = 304, number of terms = 26 Case 6: A = 101, limit = 303, number of terms = 1 The thing is this has to execute within 3sec time interval otherwise your question won't be accepted as solution, here is with what I've come up so far, its working as it should just the execution time is not within 3 seconds, here is code : import java.util.Scanner; class Main { public static void main(String[] args) { Scanner stdin = new Scanner(System.in); int start; int limit; int terms; int a = 0; while (stdin.hasNext()) { start = stdin.nextInt(); limit = stdin.nextInt(); if (start > 0) { terms = getLength(start, limit); a++; } else { break; } System.out.println("Case "+a+": A = "+start+", limit = "+limit+", number of terms = "+terms); } } public static int getLength(int x, int y) { int length = 1; while (x != 1) { if (x <= y) { if ( x % 2 == 0) { x = x / 2; length++; }else{ x = x * 3 + 1; length++; } } else { length--; break; } } return length; } } And yes here is how its meant to be solved : An algorithm given by Lothar Collatz produces sequences of integers, and is described as follows: Step 1: Choose an arbitrary positive integer A as the first item in the sequence. Step 2: If A = 1 then stop. Step 3: If A is even, then replace A by A / 2 and go to step 2. Step 4: If A is odd, then replace A by 3 * A + 1 and go to step 2. And yes my question is how can I make it work inside 3 seconds time interval?

  • Bit Reversal using bitwise

    - by Yongwei Xing
    Hi all I am trying to do bit reversal in a byte. I use the code below static int BitReversal(int n) { int u0 = 0x55555555; // 01010101010101010101010101010101 int u1 = 0x33333333; // 00110011001100110011001100110011 int u2 = 0x0F0F0F0F; // 00001111000011110000111100001111 int u3 = 0x00FF00FF; // 00000000111111110000000011111111 int x, y, z; x = n; y = (x >> 1) & u0; z = (x & u0) << 1; x = y | z; y = (x >> 2) & u1; z = (x & u1) << 2; x = y | z; y = (x >> 4) & u2; z = (x & u2) << 4; x = y | z; y = (x >> 8) & u3; z = (x & u3) << 8; x = y | z; y = (x >> 16) & u4; z = (x & u4) << 16; x = y | z; return x; } It can reverser the bit (on a 32-bit machine), but there is a problem, For example, the input is 10001111101, I want to get 10111110001, but this method would reverse the whole byte including the heading 0s. The output is 10111110001000000000000000000000. Is there any method to only reverse the actual number? I do not want to convert it to string and reverser, then convert again. Is there any pure math method or bit operation method? Best Regards,

  • How to run a powershell script within a DOS batch file

    - by Don Vince
    How do I have a powershell script embedded within the same file as a DOS batch script? I know this kind of thing is possible in other scenarios: Embedding SQL in a DOS batch script using sqlcmd and a clever arrangements of goto's and comments at the beginning of the file In a *nix environment having a the name of the program you wish to run the script with on the first line of the script commented out e.g. #!/usr/local/bin/python There may not be a way to do this - in which case I will have to call the separate powershell script from the launching DOS script. One possible solution I've considered is to echo out the powershell script, and then run it. A good reason to not do this is that part of the reason to attempt this is to be using the advantages of the powershell environment without the pain of, for example, DOS escape characters I have some unusual constraints and would like to find an elegant solution. I suspect this question may be baiting responses of the variety: "why don't you try and solve this different problem instead." Suffice to say these are my constraints, sorry about that. Any ideas? Is there a suitable combination of clever comments and escape characters that will enable me to achieve this? Some thoughts on how to achieve this: A carat ^ at the end of a line in DOS is a continuation - like an underscore in VB An ampersand & in DOS typically is used to separate commands echo Hello & echo World results in 2 echos on separate lines %0 will give you the script that's currently running So something like this (if I could make it work) would be good: # & call powershell -psconsolefile %0 # & goto :EOF /* From here on in we're running nice juicy powershell code */ Write-Output "Hello World" Except... It doesn't work... because the extension of the file isn't as per powershell's liking: Windows PowerShell console file "insideout.bat" extension is not psc1. Windows PowerShell console file extension must be psc1. DOS isn't really altogether happy with the situation either - although it does stumble on '#' is not recognized as an internal or external command, operable program or batch file.

  • XNA - Keyboard text input

    - by Sekhat
    Okay, so basically I want to be able to retrieve keyboard text. Like entering text into a text field or something. I'm only writing my game for windows. I've disregarded using Guide.BeginShowKeyboardInput because it breaks the feel of a self contained game, and the fact that the Guide always shows XBOX buttons doesn't seem right to me either. Yes it's the easiest way, but I don't like it. Next I tried using System.Windows.Forms.NativeWindow. I created a class that inherited from it, and passed it the Games window handle, implemented the WndProc function to catch WM_CHAR (or WM_KEYDOWN) though the WndProc got called for other messages, WM_CHAR and WM_KEYDOWN never did. So I had to abandon that idea, and besides, I was also referencing the whole of Windows forms, which meant unnecessary memory footprint bloat. So my last idea was to create a Thread level, low level keyboard hook. This has been the most successful so far. I get WM_KEYDOWN message, (not tried WM_CHAR yet) translate the virtual keycode with Win32 funcation MapVirtualKey to a char. And I get my text! (I'm just printing with Debug.Write at the moment) A couple problems though. It's as if I have caps lock on, and an unresponsive shift key. (Of course it's not however, it's just that there is only one Virtual Key Code per key, so translating it only has one output) and it adds overhead as it attaches itself to the Windows Hook List and isn't as fast as I'd like it to be, but the slowness could be more due to Debug.Write. Has anyone else approached this and solved it, without having to resort to an on screen keyboard? or does anyone have further ideas for me to try? thanks in advance. note: This is cross posted from the XNA Creators Forums, so if I get an answer there I'll post it here and Vice-Versa Question asked by Jimmy Maybe I'm not understanding the question, but why can't you use the XNA Keyboard and KeyboardState classes? My comment: It's because though you can read keystates, you can't get access to typed text as and how it is typed by the user. So let me further clarify. I want to implement being able to read text input from the user as if they are typing into textbox is windows. The keyboard and KeyboardState class get states of all keys, but I'd have to map each key and combination to it's character representation. This falls over when the user doesn't use the same keyboard language as I do especially with symbols (my double quotes is shift + 2, while american keyboards have theirs somewhere near the return key).

  • log4net: what am I doing wrong?

    - by Berryl
    Being a log4net newb / boob I just copied lines from an NHibernate example project where I can see the log.txt file is updated. Is there a quick answer why mine isn't creating the file? Cheers, Berryl [assembly: log4net.Config.XmlConfigurator(Watch = true)] I saw another post here saying this should go in AssemblyInfo, but in the example project this is just another line in a static helper class. Not wanting to 'mess with' assemblyInfo I also put this in a static helper, along with the following to actually log in the same static helper class: private static readonly log4net.ILog _log = log4net.LogManager.GetLogger( System.Reflection.MethodBase.GetCurrentMethod().DeclaringType ); And in app.config, I have <configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> </configSections> <!-- This section contains the log4net configuration settings --> <log4net> <!-- Define an output appender (where the logs can go) --> <appender name="LogFileAppender" type="log4net.Appender.FileAppender, log4net"> <param name="File" value="log.txt" /> <param name="AppendToFile" value="false" /> <layout type="log4net.Layout.PatternLayout, log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n" /> </layout> </appender> <appender name="LogDebugAppender" type="log4net.Appender.DebugAppender, log4net"> <layout type="log4net.Layout.PatternLayout, log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] &lt;%X{auth}&gt; - %m%n"/> </layout> </appender> <!-- Setup the root category, set the default priority level and add the appender(s) (where the logs will go) --> <root> <priority value="ALL" /> <appender-ref ref="LogFileAppender" /> <appender-ref ref="LogDebugAppender"/> </root> <!-- Specify the level for some specific namespaces --> <!-- Level can be : ALL, DEBUG, INFO, WARN, ERROR, FATAL, OFF --> <logger name="NHibernate"> <level value="ALL" /> </logger> </log4net>

  • IE6 and fieldset background color?

    - by codemonkey613
    Hey, I'm having some difficulty with CSS and IE6 compatibility. URL: http://bit.ly/dlX7cS Problem #1: I put a background image on the fieldset around Canada and United States. In IE6 and IE7, the background bleeds above the border-top of the fieldset. So, I found a fix. It is applied only to IE browsers, and moves the legend up a few pixels, aligning the background correctly. <!-- Fix: IE6/IE7, Legends --> <!--[if lte IE 7]> <style type="text/css"> fieldset { position: relative; } fieldset legend { position: absolute; top: -0.5em; left: 0; } </style> <![endif]--> This fixes IE7. But in IE6, it seems to make my legend for Canada vanish completely. Does anyone have a copy of IE6 they can open my site and tell me if you see Canada label. (I am testing with a multi-IE program, and it keeps crashing. My copy might not be accurate). If it's not there, any suggestions on how to fix it? Also, any suggestion on where I can download working copy of IE6? Problem #2: I have a Google Map embedded using iframe. The width of that iframe is 515px. In Firefox, Chrome, IE7 -- that is the correct alignment. But in IE6, it gets <br/> underneath the Just Energy paragraph beside it. It doesn't fit. I have to change width to 513px for it to fit. Uhm, anyone know where those 2px of difference happen? I removed border, padding, margin from the iframe, but still something is happening. <!-- Google Maps --> <iframe class="gmap" src="http://maps.google.com/maps/ms?hl=en&amp;ie=UTF8&amp;msa=0&amp;msid=100146512697135839835.000481e2a2779e8865863&amp;ll=42,-100&amp;spn=20,80&amp;output=embed" frameborder="0" marginheight="0" marginwidth="0" scrolling="no"></iframe> <!-- / Google Maps --> Er, big headache. lol

  • Need help implementing simple socket server using GIOService (GLib, Glib-GIO)

    - by Mark Renouf
    I'm learning the basics of writing a simple, efficient socket server using GLib. I'm experimenting with GSocketService. So far I can only seem to accept connections but then they are immediately closed. From the docs I can't figure out what step I am missing. I'm hoping someone can shed some light on this for me. When running the following: # telnet localhost 4000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. # telnet localhost 4000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host. # telnet localhost 4000 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. Connection closed by foreign host.

  • Python: How to read huge text file into memory

    - by asmaier
    I'm using Python 2.6 on a Mac Mini with 1GB RAM. I want to read in a huge text file $ ls -l links.csv; file links.csv; tail links.csv -rw-r--r-- 1 user user 469904280 30 Nov 22:42 links.csv links.csv: ASCII text, with CRLF line terminators 4757187,59883 4757187,99822 4757187,66546 4757187,638452 4757187,4627959 4757187,312826 4757187,6143 4757187,6141 4757187,3081726 4757187,58197 So each line in the file consists of a tuple of two comma separated integer values. I want to read in the whole file and sort it according to the second column. I know, that I could do the sorting without reading the whole file into memory. But I thought for a file of 500MB I should still be able to do it in memory since I have 1GB available. However when I try to read in the file, Python seems to allocate a lot more memory than is needed by the file on disk. So even with 1GB of RAM I'm not able to read in the 500MB file into memory. My Python code for reading the file and printing some information about the memory consumption is: #!/usr/bin/python # -*- coding: utf-8 -*- import sys infile=open("links.csv", "r") edges=[] count=0 #count the total number of lines in the file for line in infile: count=count+1 total=count print "Total number of lines: ",total infile.seek(0) count=0 for line in infile: edge=tuple(map(int,line.strip().split(","))) edges.append(edge) count=count+1 # for every million lines print memory consumption if count%1000000==0: print "Position: ", edge print "Read ",float(count)/float(total)*100,"%." mem=sys.getsizeof(edges) for edge in edges: mem=mem+sys.getsizeof(edge) for node in edge: mem=mem+sys.getsizeof(node) print "Memory (Bytes): ", mem The output I got was: Total number of lines: 30609720 Position: (9745, 2994) Read 3.26693612356 %. Memory (Bytes): 64348736 Position: (38857, 103574) Read 6.53387224712 %. Memory (Bytes): 128816320 Position: (83609, 63498) Read 9.80080837067 %. Memory (Bytes): 192553000 Position: (139692, 1078610) Read 13.0677444942 %. Memory (Bytes): 257873392 Position: (205067, 153705) Read 16.3346806178 %. Memory (Bytes): 320107588 Position: (283371, 253064) Read 19.6016167413 %. Memory (Bytes): 385448716 Position: (354601, 377328) Read 22.8685528649 %. Memory (Bytes): 448629828 Position: (441109, 3024112) Read 26.1354889885 %. Memory (Bytes): 512208580 Already after reading only 25% of the 500MB file, Python consumes 500MB. So it seem that storing the content of the file as a list of tuples of ints is not very memory efficient. Is there a better way to do it, so that I can read in my 500MB file into my 1GB of memory?

  • custom listview adapter getView method being called multiple times, and in no coherent order

    - by edzillion
    I have a custom list adapter: class ResultsListAdapter extends ArrayAdapter<RecordItem> { in the overridden 'getView' method I do a print to check what position is and whether it is a convertView or not: @Override public View getView(int position, View convertView, ViewGroup parent) { System.out.println("getView " + position + " " + convertView); The output of this (when the list is first displayed, no user input as yet) 04-11 16:24:05.860: INFO/System.out(681): getView 0 null 04-11 16:24:29.020: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43d415d8 04-11 16:25:48.070: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.110: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43d415d8 04-11 16:25:49.710: INFO/System.out(681): getView 0 android.widget.RelativeLayout@43d415d8 04-11 16:25:50.251: INFO/System.out(681): getView 1 null 04-11 16:26:01.300: INFO/System.out(681): getView 2 null 04-11 16:26:02.020: INFO/System.out(681): getView 3 null 04-11 16:28:28.091: INFO/System.out(681): getView 0 null 04-11 16:37:46.180: INFO/System.out(681): getView 1 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.091: INFO/System.out(681): getView 2 android.widget.RelativeLayout@43cff8f0 04-11 16:37:47.730: INFO/System.out(681): getView 3 android.widget.RelativeLayout@43cff8f0 AFAIK, though I couldn't find it stated explicitly, getView() is only called for visible rows. Since my app starts with four visible rows at least the position numbers cycling from 0-3 makes sense. But the rest is a mess: Why is getview called for each row four times? Where are these convertViews coming from when I haven't scrolled yet? I did a bit of reseach, and without getting a good answer, I did notice that people were associating this issue with layout issues. So in case, here's the layout that contains the list: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="fill_parent" android:layout_width="fill_parent" android:orientation="vertical" > <TextView android:id="@+id/pageDetails" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@+id/list" android:layout_width="fill_parent" android:layout_height="wrap_content" android:drawSelectorOnTop="false" /> </LinearLayout> and the layout of each individual row: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="108dp" android:padding="4dp"> <ImageView android:id="@+id/thumb" android:layout_width="120dp" android:layout_height="fill_parent" android:layout_alignParentTop="true" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_marginRight="8dp" android:src="@drawable/loading" /> <TextView android:id="@+id/price" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentBottom="true" android:singleLine="true" /> <TextView android:id="@+id/date" android:layout_width="wrap_content" android:layout_height="18dp" android:layout_alignParentBottom="true" android:layout_alignParentRight="true" android:paddingRight="4dp" android:singleLine="true" /> <TextView android:id="@+id/title" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="17dp" android:layout_toRightOf="@id/thumb" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:paddingRight="4dp" android:layout_alignWithParentIfMissing="true" android:gravity="center" /> Thank you for your time

  • The Skyline Problem.

    - by zeroDivisible
    I just came across this little problem on UVA's Online Judge and thought, that it may be a good candidate for a little code-golf. The problem: You are to design a program to assist an architect in drawing the skyline of a city given the locations of the buildings in the city. To make the problem tractable, all buildings are rectangular in shape and they share a common bottom (the city they are built in is very flat). The city is also viewed as two-dimensional. A building is specified by an ordered triple (Li, Hi, Ri) where Li and Ri are left and right coordinates, respectively, of building i and Hi is the height of the building. In the diagram below buildings are shown on the left with triples (1,11,5), (2,6,7), (3,13,9), (12,7,16), (14,3,25), (19,18,22), (23,13,29), (24,4,28) and the skyline, shown on the right, is represented by the sequence: 1, 11, 3, 13, 9, 0, 12, 7, 16, 3, 19, 18, 22, 3, 23, 13, 29, 0 The output should consist of the vector that describes the skyline as shown in the example above. In the skyline vector (v1, v2, v3, ... vn) , the vi such that i is an even number represent a horizontal line (height). The vi such that i is an odd number represent a vertical line (x-coordinate). The skyline vector should represent the "path" taken, for example, by a bug starting at the minimum x-coordinate and traveling horizontally and vertically over all the lines that define the skyline. Thus the last entry in the skyline vector will be a 0. The coordinates must be separated by a blank space. If I will not count declaration of provided (test) buildings and including all spaces and tab characters, my solution, in Python, is 223 characters long. Here is the condensed version: B=[[1,11,5],[2,6,7],[3,13,9],[12,7,16],[14,3,25],[19,18,22],[23,13,29],[24,4,28]] # Solution. R=range v=[0 for e in R(max([y[2] for y in B])+1)] for b in B: for x in R(b[0], b[2]): if b[1]>v[x]: v[x]=b[1] p=1 k=0 for x in R(len(v)): V=v[x] if p and V==0: continue elif V!=k: p=0 print "%s %s" % (str(x), str(V)), k=V I think that I didn't made any mistake but if so - feel free to criticize me. EDIT I don't have much reputation, so I will pay only 100 for a bounty - I am curious, if anyone could try to solve this in less than .. lets say, 80 characters. Solution posted by cobbal is 101 characters long and currently it is the best one. ANOTHER EDIT I thought, that 80 characters is a sick limit for this kind of problem. cobbal, with his 46 character solution totaly amazed me - though I must admit, that I spent some time reading his explanation before I partially understood what he had written.

  • GMF - programmatically create connections without commands

    - by user1437515
    Hi I am developing an graphical editor with GMF and want to create a set of nodes (Resources in my project) and connections between them upon intialization of a new diagram. I do not want to use commands here because without the code is much slimmer, easier to read and also faster it seems to me. There is no problem creating nodes by calling my XXXFactory.eInstance.createResource() and adding them to the diagram model. My connection is contained as source-/targetConnections feature in the resource class. So I added a similarly created connection as source/target to the resources. But it will not show up in the diagram even though it exists in the ResourceImpl structural feature. Maybe I need to add it additionally to the diagram but since its contained by a feature contained by the diagram, I dont know how. Am i doing something wrong or missing something or is it just not possible to do this without commands. Any help would be much appreciated. Sample code is below. The output of it is the two nodes but no connection. Thanks Lars Example createInitialModel method: private static RDFEditor.ShapesDiagram createInitialModel() { ShapesDiagram diagram = >RDFEditor.RDFEditorFactory.eINSTANCE.createShapesDiagram(); RDFEditor.Resource res = RDFEditorFactory.eINSTANCE.createResource(); RDFEditor.Resource res2 = RDFEditorFactory.eINSTANCE.createResource(); Connection con = RDFEditorFactory.eINSTANCE.createConnection(); EStructuralFeature target = >res.eClass().getEStructuralFeature("targetConnections"); EStructuralFeature source = >res.eClass().getEStructuralFeature("sourceConnections"); res2.setName("rdfs:Resource"); res.setName("rdfs:Class"); con.setName("rdfs:type"); con.setSource(res); con.setTarget(res2); res.getSourceConnections().add(con); res.getTargetConnections().add(con); //res2.eSet(target, con); //res.eSet(source, con); List<? extends Shape> resList = Arrays.asList(res,res2); EStructuralFeature shapes = >diagram.eClass().getEStructuralFeature("shapes"); diagram.eSet(shapes, resList); return diagram; }

  • C++ How to deep copy a struct with unknown datatype?

    - by Ewald Peters
    hi, i have a "data provider" which stores its output in a struct of a certain type, for instance struct DATA_TYPE1{ std::string data_string; }; then this struct has to be casted into a general datatype, i thought about void * or char *, because the "intermediate" object that copies and stores it in its binary tree should be able to store many different types of such struct data. struct BINARY_TREE_ENTRY{ void * DATA; struct BINARY_TREE_ENTRY * next; }; this void * is then later taken by another object that casts the void * back into the (struct DATA_TYPE1 *) to get the original data. so the sender and the receiver know about the datatype DATA_TYPE1 but not the copying object inbetween. but how can the intermidiate object deep copy the contents of the different structs, when it doesn't know the datatype, only void * and it has no method to copy the real contents; dynamic_cast doesn't work for void *; the "intermediate" object should do something like: void store_data(void * CASTED_DATA_STRUCT){ void * DATA_COPY = create_a_deepcopy_of(CASTED_DATA_STRUCT); push_into_bintree(DATA_COPY); } a simple solution would be that the sending object doesn't delete the sent data struct, til the receiving object got it, but the sending objects are dynamically created and deleted, before the receiver got the data from the intermediate object, for asynchronous communication, therefore i want to copy it. instead of converting it to void * i also tried converting to a superclass pointer of which the intermediate copying object knows about, and which is inherited by all the different datatypes of the structs: struct DATA_BASE_OBJECT{ public: DATA_BASE_OBJECT(){} DATA_BASE_OBJECT(DATA_BASE_OBJECT * old_ptr){ std::cout << "this should be automatically overridden!" << std::endl; } virtual ~DATA_BASE_OBJECT(){} }; struct DATA_TYPE1 : public DATA_BASE_OBJECT { public: string str; DATA_TYPE1(){} ~DATA_TYPE1(){} DATA_TYPE1(DATA_TYPE1 * old_ptr){ str = old_ptr->str; } }; and the corresponding binary tree entry would then be: struct BINARY_TREE_ENTRY{ struct DATA_BASE_OBJECT * DATA; struct BINARY_TREE_ENTRY * next; }; and to then copy the unknown datatype, i tried in the class that just gets the unknown datatype as a struct DATA_BASE_OBJECT * (before it was the void *): void * copy_data(DATA_BASE_OBJECT * data_that_i_get_in_the_sub_struct){ struct DATA_BASE_OBJECT * copy_sub = new DATA_BASE_OBJECT(data_that_i_get_in_the_sub_struct); push_into_bintree(copy_sub); } i then added a copy constructor to the DATA_BASE_OBJECT, but if the struct DATA_TYPE1 is first casted to a DATA_BASE_OBJECT and then copied, the included sub object DATA_TYPE1 is not also copied. i then thought what about finding out the size of the actual object to copy and then just memcopy it, but the bytes are not stored in one row and how do i find out the real size in memory of the struct DATA_TYPE1 which holds a std::string? Which other c++ methods are available to deepcopy an unknown datatype (and to maybe get the datatype information somehow else during runtime) thanks Ewald

  • SerialPort ReadLine() after Thread.Sleep() goes crazy

    - by Mat
    Hi everybody, I've been fighting with this issue for a day and I can't find answer for it. I am trying to read data from GPS device trough COM port in Compact Framework C#. I am using SerialPort class (actually my own ComPort class boxing SerialPort, but it adds only two fields I need, nothing special). Anyway.. I am running while loop in a separate thread which reads line from the port, analyze NMEA data, print them, catch all exceptions and then I Sleep(200) the thread, cause I need CPU for other threads... Without Sleep it works fine, but uses 100% CPU.. When I dont use Sleep after few minutes the output from COM port looks like this: GPGSA,A,3,09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F GSA,A,3,09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F A,A,3,09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F ,18,12,271,24,24,05,020,24,14,04,326,25,11,03,023,*76 A,3,09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F 3,09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F 09,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F ,12,22,17,15,27,,,,,,,2.6,1.6,2.1*3F as you can see the same message is read few times but cut. I wonder what I'm doing wrong... My port configuration: port.ReadBufferSize = 4096; port.BaudRate = 4800; port.DataBits = 8; port.Parity = Parity.None; port.StopBits = StopBits.One; port.NewLine = "\r\n"; port.ReadTimeout = 1000; port.ReceivedBytesThreshold = 100000; And my reading function: private void processGps(){ while (!closing) { //reconnect if needed try { string sentence = port.ReadLine(); //here print the sentence //analyze the sentence (this takes some time 50-100ms) } catch (TimeoutException) { Thread.Sleep(0); } catch (IOException ioex) { //handling IO exception (some info on the screen) } Thread.Sleep(200); } } There is some more stuff in this function like reconnection if the device is lost etc.. but it is not called when the GPS is connected properly.. I was trying port.DiscardInBuffer(); after some blocks of code (in TimeoutException, after read..) Did anyone had similar problem? I really dont know what I'm doing wrong.. The only way to get rig of it is removing the last Sleep... Thanks in advance! Best Regards, Mat

  • Eclipselink factory.createEntityManager() stalls with more than one instance running

    - by Raven
    Hi, with my RCP program I have the problem that I want to have more than one copy running on my PC. The first instance runs very good. If I start the second instance, everything is fine until I want to access the database. Using this code: .. Map properties = new HashMap(); properties.put("javax.persistence.jdbc.driver", dbDriver); properties.put("javax.persistence.jdbc.url", dbUrl); properties.put("javax.persistence.jdbc.user", dbUser); properties.put("javax.persistence.jdbc.password", dbPass); try { factory = Persistence.createEntityManagerFactory( PERSISTENCE_UNIT_NAME, properties); } catch (Exception e) { System.out.println(e); } em=factory.createEntityManager(); // the second instance stops here ... with an persistence.xml of <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="default"> <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider> <class>myclasshere</class> <properties> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.jdbc.read-connections.min" value="1" /> <property name="eclipselink.jdbc.write-connections.min" value="1" /> <property name="eclipselink.jdbc.batch-writing" value="JDBC" /> <property name="eclipselink.logging.level" value="SEVERE" /> <property name="eclipselink.logging.timestamp" value="false" /> <property name="eclipselink.logging.session" value="false" /> <property name="eclipselink.logging.thread" value="false" /> </properties> </persistence-unit> </persistence> The program stalls / does not continue in the second instance beyond this step: em=factory.createEntityManager(); Debugging the program step by step showed me, that nothing happens at this point. Perhaps the program runs into a timeout. I havent been wainting for more than 1 minute.... Do you have any clues what might cause this stall might?

  • How to get rid of annoying HorizontalContentAlignment binding warning?

    - by marco.ragogna
    I am working on a large WPF project and during debug my output window is filled with these annoying warnings: System.Windows.Data Information: 10 : Cannot retrieve value using the binding and no valid fallback value exists; using default instead. BindingExpression:Path=HorizontalContentAlignment; DataItem=null; target element is 'ComboBoxItem' (Name=''); target property is 'HorizontalContentAlignment' (type ' HorizontalAlignment') In the specific example ComboBoxItem is styled in this way: <Style x:Key="{x:Type ComboBoxItem}" TargetType="{x:Type ComboBoxItem}"> <Setter Property="OverridesDefaultStyle" Value="True"/> <Setter Property="SnapsToDevicePixels" Value="True"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type ComboBoxItem}"> <Border Name="bd" Padding="4,4,4,4" SnapsToDevicePixels="True" CornerRadius="2,2,2,2"> <ContentPresenter /> </Border> <ControlTemplate.Triggers> <Trigger Property="IsHighlighted" Value="true"> <Setter TargetName="bd" Property="Background" Value="{StaticResource MediumBrush}"/> <Setter TargetName="bd" Property="Padding" Value="4,4,4,4"/> <Setter TargetName="bd" Property="CornerRadius" Value="2,2,2,2"/> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style> I know that the problem is generated by the default theme definition for ComboBoxItem that contains things like: <Setter Property="Control.HorizontalContentAlignment"> <Setter.Value> <Binding Path="HorizontalContentAlignment" RelativeSource="{RelativeSource Mode=FindAncestor, AncestorType=ItemsControl, AncestorLevel=1}" /> </Setter.Value> </Setter> but I also thought that using <Setter Property="OverridesDefaultStyle" Value="True"/> would taken care of the problem, and instead warnings are still there. Any help is really appreciated

  • Bluetooth connect to a RS232 adapter in android

    - by ThePosey
    Hello All, I am trying to use the Bluetooth Chat sample API app that google provides to connect to a bluetooth RS232 adapter hooked up to another device. Here is the app for reference: http://developer.android.com/resources/samples/BluetoothChat/index.html And here is the spec sheet for the RS232 connector just for reference: http://serialio.com/download/Docs/BlueSnap-guide-4.77%5FCommands.pdf Well the problem is that when I go to connect to the device with: mmSocket.connect(); (BluetoothSocket::connect()) I always get an IOException error thrown by the connect method. When I do a toString on the exception I get "Service discovery failed". My question is mostly what are the cases that would cause an IOException to get thrown in the connect method? I know those are in the source somewhere but I don't know exactly how the java layer that you write apps in and the C/C++ layer that contains the actual stacks interface. I know that it uses the bluez bluetooth stack which is written in C/C++ but not sure how that ties into the java layer which is what I would think is throwing the exception. Any help on pointing me to where I can try to dissect this issue would be incredible. Also just to note I am able to pair with the RS232 adapter just fine but I am never able to actually connect. Here is the logcat output for more reference: I/ActivityManager( 1018): Displayed activity com.example.android.BluetoothChat/.DeviceListActivity: 326 ms (total 326 ms) E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) D/BluetoothChat( 1729): onActivityResult -1 D/BluetoothChatService( 1729): connect to: 00:06:66:03:0C:51 D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_CONNECTING E/BluetoothChat( 1729): + ON RESUME + I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_CONNECTING I/BluetoothChatService( 1729): BEGIN mConnectThread E/BluetoothService.cpp( 1018): stopDiscoveryNative: D-Bus error in StopDiscovery: org.bluez.Error.Failed (Invalid discovery session) E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 I/BluetoothChatService( 1729): CONNECTION FAIL TOSTRING: java.io.IOException: Service discovery failed D/BluetoothChatService( 1729): setState() STATE_CONNECTING - STATE_LISTEN D/BluetoothChatService( 1729): start D/BluetoothChatService( 1729): setState() STATE_LISTEN - STATE_LISTEN I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID I/NotificationService( 1018): enqueueToast pkg=com.example.android.BluetoothChat callback=android.app.ITransientNotification$Stub$Proxy@446327c8 duration=0 I/BluetoothChat( 1729): MESSAGE_STATE_CHANGE: STATE_LISTEN E/BluetoothEventLoop.cpp( 1018): event_filter: Received signal org.bluez.Device:PropertyChanged from /org/bluez/1498/hci0/dev_00_06_66_03_0C_51 V/BluetoothEventRedirector( 1080): Received android.bleutooth.device.action.UUID The device I'm trying to connect to is the 00:06:66:03:0C:51 which I can scan for and apparently pair with just fine.

  • oci_connect Blank Page in PHP

    - by Bryan
    UPDATE (3/8/2010) I installed Xdebug and have it tracing my code. This is the output I am getting: TRACE START [2010-03-08 17:53:05] 0.2090 327864 -> {main}() /data/aims3/http/octest.php:0 0.2091 327988 -> ini_set(string(14), string(1)) /data/aims3/http/octest.php:3 0.2093 327920 -> error_reporting(long) /data/aims3/http/octest.php:4 0.2094 328048 -> oci_connect(string(8), string(8), string(25)) /data/aims3/http/octest.php:6 The trace halts at that point. I have installed everything the same way on a local server and it works fine. To say I am at a complete loss would be putting it lightly. *NOTE: I ran make test and it returned FAIL on every test. I never ran this on my working machine to see if it reports the same errors. Any idea why make test would report FAIL but make doesn't report any error? I've installed the Oracle Instantclient with no reported errors along with the OCI8 PECL package and at a loss. Whenever I try to open a connection with oci_connect, it halts my entire PHP script. EXAMPLE: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; $conn = oci_connect("username", "password", "host"); echo "after"; ?> Returns a complete blank page. The module is loaded (seen in phpinfo) and everything installed with no errors. I am at a complete loss. CentOS: 5.4 Apache: 2.2.3 PHP: 5.3.1 InstantClient: 11.2 oci8: 1.4.1 Any thoughts? NOTES Apache Error Log reports nothing Attempted Debugging: 1: <?php ini_set ("display_errors", "1"); error_reporting(E_ALL); echo "before"; if(!function_exists('oci_connect')) die('Oracle Not Installed'); echo "after"; ?> Returns: beforeafter 2: Changing host to //host Returns: Same error
