  • Batch file writing to log then ending process

    - by Andrew Service
    I have a batch file that calls a process and in that process I have: IF %ERRORLEVEL% NEQ 0 EXIT /B %ERRORLEVEL% Now I wanted to upgrade this a bit and give some meaningful message to an output log when if the process fails, also I do not want the main batch to continue processing because the next processes are dependent on data from previous calls; I wonder if this would be correct but not sure: CALL Process 1 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInfirstProcess /B %ERRORLEVEL% :ErrorInfirstProcess ECHO Process 1 Failed on %Date% at %Time%. >>C:\Log.txt" CALL Process 2 IF %ERRORLEVEL% NEQ 0 GOTO ErrorInSecondProcess /B %ERRORLEVEL% :ErrorInSecondProcess ECHO Process 2 Failed on %Date% at %Time%. >>C:\Log.txt" I also want to know if I still need the /B or do I need to put an EXIT command after the echo? Thanks A

  • Writing functions of tuples conveniently in Scala

    - by Alexey Romanov
    Quite a few functions on Map take a function on a key-value tuple as the argument. E.g. def foreach(f: ((A, B)) ? Unit): Unit. So I looked for a short way to write an argument to foreach: > val map = Map(1 -> 2, 3 -> 4) map: scala.collection.immutable.Map[Int,Int] = Map(1 -> 2, 3 -> 4) > map.foreach((k, v) => println(k)) error: wrong number of parameters; expected = 1 map.foreach((k, v) => println(k)) ^ > map.foreach({(k, v) => println(k)}) error: wrong number of parameters; expected = 1 map.foreach({(k, v) => println(k)}) ^ > map.foreach(case (k, v) => println(k)) error: illegal start of simple expression map.foreach(case (k, v) => println(k)) ^ I can do > map.foreach(_ match {case (k, v) => println(k)}) 1 3 Any better alternatives?

  • Writing an Eval Procedure in Scheme?

    - by Planeman
    My problem isn't with the built-in eval procedure but how to create a simplistic version of it. Just for starters I would like to be able to take this in '(+ 1 2) and have it evaluate the expression + where the quote usually takes off the evaluation. I have been thinking about this and found a couple things that might be useful: Unquote: , (quasiquote) (apply) My main problem is regaining the value of + as a procedure and not a symbol. Once I get that I think I should just be able to use it with the other contents of the list. Any tips or guidance would be much appreciated.

  • Guide on writing my first open source software ?

    - by Kim Jong Woo
    Hello Stackoverflow, Since last August 2009, I have been working on project but then decided to release it as an open source project. The purpose of this project is to provide an alternative to existing commercial & expensive solution. So my question is, how can I get started ? The prototype has been ready since May and now being rewritten in Java. Which license type do I need to pursue ? LGPL? MIT? Thank you, John.

  • Writing a synchronized thread-safety wrapper for NavigableMap

    - by polygenelubricants
    java.util.Collections currently provide the following utility methods for creating synchronized wrapper for various collection interfaces: synchronizedCollection(Collection<T> c) synchronizedList(List<T> list) synchronizedMap(Map<K,V> m) synchronizedSet(Set<T> s) synchronizedSortedMap(SortedMap<K,V> m) synchronizedSortedSet(SortedSet<T> s) Analogously, it also has 6 unmodifiedXXX overloads. The glaring omission here are the utility methods for NavigableMap<K,V>. It's true that it extends SortedMap, but so does SortedSet extends Set, and Set extends Collection, and Collections have dedicated utility methods for SortedSet and Set. Presumably NavigableMap is a useful abstraction, or else it wouldn't have been there in the first place, and yet there are no utility methods for it. So the questions are: Is there a specific reason why Collections doesn't provide utility methods for NavigableMap? How would you write your own synchronized wrapper for NavigableMap? Glancing at the source code for OpenJDK version of Collections.java seems to suggest that this is just a "mechanical" process Is it true that in general you can add synchronized thread-safetiness feature like this? If it's such a mechanical process, can it be automated? (Eclipse plug-in, etc) Is this code repetition necessary, or could it have been avoided by a different OOP design pattern?

  • Writing out sheet to text file using POI event model

    - by Eduardo Dennis
    I am using XLSX2CSV example to parse large sheets from a workbook. Since I only need to output the data for specific sheets I added an if statement in the process method to test for the specific sheets. When the condition is met I continue with the process. public void process() throws IOException, OpenXML4JException, ParserConfigurationException, SAXException { ReadOnlySharedStringsTable strings = new ReadOnlySharedStringsTable(this.xlsxPackage); XSSFReader xssfReader = new XSSFReader(this.xlsxPackage); StylesTable styles = xssfReader.getStylesTable(); XSSFReader.SheetIterator iter = (XSSFReader.SheetIterator) xssfReader.getSheetsData(); while (iter.hasNext()) { InputStream stream = iter.next(); String sheetName = iter.getSheetName(); if (sheetName.equals("SHEET1")||sheetName.equals("SHEET2")||sheetName.equals("SHEET3")||sheetName.equals("SHEET4")||sheetName.equals("SHEET5")){ processSheet(styles, strings, stream); try { System.setOut(new PrintStream( new FileOutputStream("C:\\Users\\edennis.AD\\Desktop\\test\\"+sheetName+".txt"))); } catch (Exception e) { e.printStackTrace(); } stream.close(); } } } But I need to output text file and not sure how to do it. I tried to use the System.set() method to output everything from system.out to text but that's not working I just get blank files.

  • Help with IE bugs when writing JSON via an ASPX response

    - by Jereme
    I have an ASPX page that I am using to write JSON. It works great in Firefox and Chrome, but when I try and use it in IE 8 it gives me an "The XML page cannot be displayed" error instead of allowing jQuery to load the JSON being written by the response. Any ideas? Here is what my code looks like: protected override void OnLoad(EventArgs e) { Response.Clear(); Response.ClearHeaders(); Response.ContentType = "application/json"; Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Write(string.Format("[ {{ \"Foo\": \"{0}\", \"bar\": \"{1}\" }} ]", "Foo Content", "Bar Content")); Response.End(); }

  • Powershell: Writing errors and ouput to a text file and Console

    - by smaclell
    I am trying to write the entire output (errors included) of an executing script to the console and a file at the same time. I have tried several different options .\MyScript.ps1 | tee -filePath C:\results.txt # only the output to the file .\MyScript.ps1 2> C:\results.txt # only the errors to the file and not the console .\MyScript.ps1 > C:\results.txt # only the output to the file and not the console My hope was that I could use the file to review the output/errors Any help would be greatly appreciated.

  • Problem with reading and writing to binary file in C++

    - by Reem
    I need to make a file that contains "name" which is a string -array of char- and "data" which is array of bytes -array of char in C++- but the first problem I faced is how to separate the "name" from the "data"? newline character could work in this case (assuming that I don't have "\n" in the name) but I could have special characters in the "data" part so there's no way to know when it ends so I'm putting an int value in the file before the data which has the size of the "data"! I tried to do this with code as follow: if((fp = fopen("file.bin","wb")) == NULL) { return false; } char buffer[] = "first data\n"; fwrite( buffer ,1,sizeof(buffer),fp ); int number[1]; number[0]=10; fwrite( number ,1,1, fp ); char data[] = "1234567890"; fwrite( data , 1, number[0], fp ); fclose(fp); but I didn't know if the "int" part was right, so I tried many other codes including this one: char buffer[] = "first data\n"; fwrite( buffer ,1,sizeof(buffer),fp ); int size=10; fwrite( &size ,sizeof size,1, fp ); char data[] = "1234567890"; fwrite( data , 1, number[0], fp ); I see 4 "NULL" characters in the file when I open it instead of seeing an integer. Is that normal? The other problem I'm facing is reading that again from the file! The code I tried to read didn't work at all :( I tried it with "fread" but I'm not sure if I should use "fseek" with it or it just read the other character after it. Forgive me but I'm a beginner :(

  • fopen / fopen_s and writing to files

    - by yCalleecharan
    Hi, I'm using fopen in C to write the output to a text file. The function declaration is (where ARRAY_SIZE has been defined earlier): void create_out_file(char file_name[],long double *z1){ FILE *out; int i; if((out = fopen(file_name, "w+")) == NULL){ fprintf(stderr, "* Open error on output file %s", file_name); exit(-1); } for(i = 0; i < ARRAY_SIZE; i++) fprintf(out, "%.16Le\n", z1[i]); fclose(out); } My questions: On compilation with MVS2008 I get the warning: warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. I haven't see much information on fopen_s so that I can change my code. Any suggestions? Can one instruct fprintf to write at desired precision? If I'm using long double then I assume that my answers are good till 15 digits after the decimal point. Am I right? Thanks a lot...

  • Am I writing this right? [noob]

    - by Aaron
    private final int NUM_SOUND_FILES = 4; private Random rnd = new Random(4); private int mfile[] = new mfile[NUM_SOUND_FILES]; //the second mfile //reports error everytime mfile[0] = R.raw.sound1; mfile[1] = R.raw.sound2; mfile[2] = R.raw.sound3; mfile[3] = R.raw.sound4; int sndToPlay = rnd.nextInt(NUM_SOUND_FILES); I keep getting syntax errors no matter how I write it. And when I get the syntax right, it forcecloses. Here's with the alleged "correct" syntax but forcecloses: private final int NUM_SOUND_FILES = 4; private Random rnd = new Random(4); private int mfile[] = new int[NUM_SOUND_FILES];{ mfile[0] = R.raw.sound1; mfile[1] = R.raw.sound2; mfile[2] = R.raw.sound3; mfile[3] = R.raw.sound4;}

  • Writing a filter for incoming connections

    - by Kornel Kisielewicz
    I'm using C++/boost::asio under Win7. I'm trying to "sniff" trafic over a given TCP/IP port. Hence, I'd like to listen on that port, receive messages, analyze them, but also immidately allow them to flow further, as if I never intercepted them. I want them to sink into the program that normally listens and connects on that port. Imagine a transparent proxy, but not for HTTP. I'd rather find a code-based solution, but barring that, maybe you would suggest a tool?

  • Writing Lucene StandardAnalyzer results to text file with OutputStreamWriter

    - by user3693192
    I'm getting ONLY the last result written to "outputStreamFile.txt". Can't figure out how to revise code so I can get ALL results written to text file. Sample input text: "1st line of text\n" "2nd line of text \n" Results in only 2nd line begin written (and not 1st line) as: "2nd line text\n" private static void analyze(String text) throws IOException { analyzer = new StandardAnalyzer(Version.LUCENE_30); Reader r = new StringReader(text); TokenStream ts = (TokenStream) analyzer.tokenStream("", r); TermAttribute term = ts.addAttribute(TermAttribute.class); File outfile = new File("C:\\Users\\Desktop\\outputStreamFile.txt"); FileOutputStream fileOutputStream = new FileOutputStream(outfile); OutputStreamWriter outputStreamWriter = new OutputStreamWriter(fileOutputStream, "UTF8"); while(ts.incrementToken()) { //System.out.print(term.term() + " "); outputStreamWriter.write(term.term().toString() + "\r\n"); } outputStreamWriter.close(); }

  • Writing a script to bypass college login page

    - by gtredcvb
    My college has a silly login page that requires you to download a whole bunch of garbage that a lot of us don't need (Norton Anti-virus, Antispyware software, etc.). We have to have them running to get on the internet on campus. Though, if you are on Linux, or at least set your user-agent to linux, the requirements are gone. We could easily use Firefox with the useragent switcher to bypass this, but it'd be nice to create a script that automates this. How would this be possible? I figure this could be written in python, and could grab the webpage with curl specifying a user agent? How would I go about posting the data back to the servers? Thanks

  • Test-driven Development: Writing tests for private / protected variables

    - by Chetan
    I'm learning TDD, and I have a question about private / protected variables. My question is: If a function I want to test is operating on a private variable, how should I test it? Here is the example I'm working with: I have a class called Table that contains an instance variable called internalRepresentation that is a 2D array. I want to create a function called multiplyValuesByN that multiplies all the values in the 2D array by the argument n. So I write the test for it (in Python): def test_multiplyValuesByN (self): t = Table(3, 3) # 3x3 table, filled with 0's t.set(0, 0, 4) # Set value at position (0,0) to 4 t.multiplyValuesByN(3) assertEqual(t.internalRepresentation, [[12, 0, 0], [0, 0, 0], [0, 0, 0]]) Now, if I make internalRepresentation private or protected, this test will not work. How am I supposed to write the test so it doesn't depend on internalRepresentation but still tests that it looks correct after calling multiplyValuesByN?

  • javan-whenever not writing crontab with Capistrano deploy

    - by Gordon Isnor
    I’ve been trying to get whenever running on an ec2 instance that was created with ec2 on rails. When I deploy with Capistrano it indicates that the crontab was written, but when I log into the server and run crontab -l it does not seem to have been changed. If I go into the release folder and manually run whenever --write-crontab then run crontab -l - it gets updated properly. Any ideas what could be causing this? Capistrano is not indicating any errors so not sure how to debug, have tried a billion permutations and combinations and nothing changes.

  • Access is re-writing - and breaking - my query!

    - by FrustratedWithFormsDesigner
    I have a query in MS Access (2003) that makes use of a subquery. The subquery part looks like this: ...FROM (SELECT id, dt, details FROM all_recs WHERE def_cd="ABC-00123") AS q1,... And when I switch to Table View to verify the results, all is OK. Then, I wanted the result of this query to be printed on the page header for a report (the query returns a single row that is page-header stuff). I get an error because the query is suddenly re-written as: ...FROM [SELECT id, dt, details FROM all_recs WHERE def_cd="ABC-00123"; ] AS q1,... So it's Ok that the round brackets are automatically replaced by square brackets, Access feels it needs to do that, fine! But why is it adding the ; into the subquery, which causes it to fail? I suppose I could just create new query objects for these subqueries, but it seems a little silly that I should have to do that.

  • Writing a printList method for a Scheme interpreter in C

    - by Rehan Rasool
    I am new to C and working on making an interpreter for Scheme. I am trying to get a suitable printList method to traverse through the structure. The program takes in an input like: (a (b c)) and internally represent it as: [""][ ][ ]--> [""][ ][/] | | ["A"][/][/] [""][ ][ ]--> [""][ ][/] | | ["B"][/][/] ["C"][/][/] Right now, I just want the program to take in the input, make the appropriate cell structure internally and print out the cell structure, thereby getting (a (b c)) at the end. Here is my struct: typedef struct conscell *List; struct conscell { char symbol; struct conscell *first; struct conscell *rest; }; void printList(char token[20]){ List current = S_Expression(token, 0); printf("("); printf("First Value? %c \n", current->first->symbol); printf("Second value? %c \n", current->rest->first->first->symbol); printf("Third value? %c \n", current->rest->first->rest->first->symbol); printf(")"); } In the main method, I get the first token and call: printList(token); I tested the values again for the sublists and I think it is working. However, I will need a method to traverse through the whole structure. Please look at my printList code again. The print calls are what I have to type, to manually get the (a (b c)) list values. So I get this output: First value? a First value? b First value? c It is what I want, but I want a method to do it using a loop, no matter how complex the structure is, also adding brackets where appropriate, so in the end, I should get: (a (b c)) which is the same as the input. Can anyone please help me with this?

  • Writing C# GUI over a C++ dll or C++ exe

    - by user97642
    Hi I have a C++ console Exe which does some progamming. Now i wanted to write a C# GUI which does some of the programming that the C++ exe does. I was thinking of few approaches, Write the C# GUI with all programming in C++ done from scratch.(I do not want to do this for the amount of rework it entails) Build a C++ dll which does the programming and have it imported in GUI app.(Now here i have a concern. How do i capture the output of the routines in c++ dll and display it in GUI? Should i return the output as string for every routine that the app calls.? Since i dont know managed c++ iam going to build an unmanaged C++ dll. )
