  • Alternative to latex / a way to typeset good looking documents from Java to PDF

    - by drasto
    I'm working on application in Java that will maintain database of song lyrics in plain text and print out some songbooks/chordbooks(that is create PDF file from selected songs). I was planing that the Java application will generate source code for pdflatex and after compiling this source user will get PDF file. Lately I've run into a lot of problems because of latex limitation: fixed memory size (some pictures will also be drawn to PDF) - error when exceeded, no way to query end of line or and of page dynamically, it's very hard to override latex placement algorithm in a complex way,... see also some my other questions regarding latex. I come to conclusion that latex is not good option for automated PDF generation. So I need replacement. I need to be able to typeset: Chords over lyrics when the lyrics are in variable char width so I need to be able to measure text width Chord diagrams that means I'll have to draw quite complex pictures Each song on separate double page Different fonts etc. Thanks for all answers

  • Android XML file doesn't save

    - by Shane
    I'm writing a game with LibGDX, and I'm trying to save an XML file, but there's always an exception (java.io.FileNotFoundException: /data/Slugfest/teams/Team1.xml: open failed: ENOENT (No such file or directory)) when saving the file. This code saves the file. public void save() { try { TransformerFactory transformerFactory = TransformerFactory.newInstance(); Transformer transformer = transformerFactory.newTransformer(); DOMSource source = new DOMSource(doc); StreamResult result; if (Gdx.app.getType() == ApplicationType.Android) { result = new StreamResult(new File("/data/Slugfest/teams/" + name + ".xml")); } else { result = new StreamResult(new File(name + ".xml")); } transformer.transform(source, result); Gdx.app.log("Slugfest", "File saved."); } catch (TransformerException tfe) { Gdx.app.log("Slugfest", tfe.getLocalizedMessage()); } } My manifest file includes the WRITE/READ_EXTERNAL_STORAGE permissions, by the way.

  • Modifying value of "Rating" column within Explorer for arbitrary file types

    - by Fake Name
    Basically, I have a large body of assorted media (text, images, flash files, archives, folders, etc...) and I'm attempting to organize it. Windows Explorer has a rating column, but there seems to be no way to modify the rating of the files short of opening them in their type-specific software (e.g. Media player, or Photo viewer). However, this does not work when the file is of an unsupported type (.rar, .swf ...), or a directory. I'd be more than willing to consider a file-manager replacement (I've alreadly looked at quite a few, Directory Opus, Total Commander, etc...), or even a solution that stores the rating metadata in a hidden file in each folder, or a separate database. The one real critical requirement is the ability to sort by rating, and being filetype-agnostic. Basically, is there any way to categorize a large collection of assorted files by rating that will work with any file type, including directories? - Ideally, there would be an easy way to add arbitrary columns to windows explorer, and edit them directly. However, there seems to be no way to do this. The rating column is the next best thing.

  • ReportViewer datadinding (WPF)

    - by user512150
    I have a rdlc file and I try to show it using report viewer control in WPF. My DataSource is called 'OfficeDataSet' and DataSet used in report is called 'Address'. I try to initialize report viewer (I put it in WindowsFormsHost) like this: private void PrepareReport() { reportDataSource = new ReportDataSource(); officeDataSet = new OfficeDataSet(); adapter = new AddressTableAdapter(); adapter.Fill(officeDataSet.Address); reportDataSource.Name = "OfficeDataSet_Address"; reportDataSource.Value = officeDataSet.Address; viewerInstance.LocalReport.DataSources.Add(reportDataSource); viewerInstance.LocalReport.ReportEmbeddedResource = "WpfApplication1.Reports.TestReport.rdlc"; viewerInstance.Location = new System.Drawing.Point(0, 0); viewerInstance.RefreshReport(); } but I got the message "A data source instance has not been supplied for the data source 'Address'". Anybody know what can be wrong with this code? (I'm totally new in WPF and Reporting Services).

  • How to make 2 executables communicate in both directions in Windows

    - by user302099
    Hello. I have 2 Windows console applications, reading from standard input and writing to standard output. I'd like to assume I don't have the source code to any of them (actually I usually have the source code of one of them). I want to direct the standard output of one to the standard input of the other and vice versa, thus allowing communication (the goal is to allow two programs playing a certain game to play one against the other). How can this be done? I'm willing to do some C/C++ programming or anything else required. Oren.

  • What are the exact versions of stuff you have to install in order to be able to step-debug a Scala p

    - by Alex R
    How do YOU debug a Scala program? I mean YOU as in the person posting the Answer :) Please answer only from personal experience, not from stuff you've heard or read on the Internet. You should not believe everything you read on the Internet, especially tales of complex open-source software configurations that actually work :-) The are many Java tools which claim to support Scala in some way or another, but I have so far struck out in trying to get any one of them to actually let me set a breakpoint in Scala code and step through it. These are big, major open-source IDEs I'm talking about here. The main problem in getting a debugger to work seems to be the "version hell" with fast-changing IDEs, Plug-Ins, JDKs, and the Scala language itself. Hence, the more detailed re-statement of the question is appropriate: What is the exact version number of the IDE, Plug-In, JDK, Scala, and even Operating System, that you are successfully using? My question is related to this one, but wider in scope: http://stackoverflow.com/questions/2272705/how-to-debug-scala-code-when-outside-of-an-ide Thanks

  • The implicit function __strcpy_chk() call

    - by Summer_More_More_Tea
    Hi everyone: I'm now performing a stack buffer overflow attack test on my own PC( Ubuntu 9.10, gcc-4.4.1 ) based on the article http://www.tenouk.com/Bufferoverflowc/Bufferoverflow4.html. Yet I haven't achieved the goal. Each time a segfault is thrown accompanied with some error informaiton. I compile the source code, and wanna get further information using objdump. Function __strcpy_chk is invoked in the assembly code dumped out, and it's said that "The __strcpy_chk() function is not in the source standard; it is only in the binary standard." Does this the mechanism a compiler employed to protect runtime stack? To finish my test, how can I bypass the protection? Regards.

  • Update music file details - Java.

    - by Desorder
    Hi all, Well, I'm a music fan guy, and now with my 18000 music collection, it's getting very hard to maintain. So, I would like to ask I could of question to help to write an app to maintain it for me. 1- How can I access a music file and read details of it? I mean, I would like to write some code and passing the directory, my app would read all the music files (understand mp3 files) and with that I would like to access details like title, artist, length and so on... 2- Is there a public source that I could access and update my file? A webservice somewhere that I could connect, query some information based on song name, or artist or whatever. I would like to achieve a final result of given a directory, my app would read the file, collect some information and query the source for a complete list of detail and update my file. Thank you guys for any help...

  • how is a macro expanded in clojure?

    - by john wang
    In the book Programming Clojure(Stuart), when read how macros are expanded I got confused. user=> (defmacro chain ([x form] (list '. x form)) ([x form & more] (concat (list 'chain (list '. x form)) more))) #'user/chain The above macro can be expanded as: user=> (macroexpand '(chain a b c)) (. (. a b) c) But the following is only expanded to the first level: user=> (macroexpand '(and a b c)) (let* [and__3822__auto__ a] (if and__3822__auto__ (clojure.core/and b c) and__3822__auto__)) The and macro source: user=> (source and) (defmacro and([] true) ([x] x) ([x & next] `(let [and# ~x] (if and# (and ~@next) and#)))) Why is the chain macro expanded all the way but the and not ? Why is it not expanded to something like the following: user=> (macroexpand '(chain a b c d)) (. (chain a b c) d)

  • Using microsoft report viewer with objects

    - by Jack
    Ive got some nested objects that I am trying to generate reports for. A BackupClient contains BackupVersions and BackupVersions contain BackupFiles. I passed in the list of BackupClients - and the report displays the client name, etc.... but to display the versions - It says I have to have a Binding Source for BackupVersions. If I pull all of the versions out of the clients and put them in a different BindingSource, then my data is no longer together - how is the report viewer going to list the versions for client X - if I just have a binding source with ALL clients versions in it?

  • Subprocess with variables & Command from different class

    - by Pastelinux
    source: http://pastebin.com/utL7Ebeq My thinking is that if i run from controller class "main" it will allow me to take the "data" from Class "model", def "filename". It doesn't seem to work. As you can see below what i mean class Controller: def __init__(self): self.model = Model() self.view = View() def main(self): data = self.model.filename() self.view.tcpdump(data) class View: def tcpdump(self, command): subprocess.call(command.split(), shell=False) When i run my code i get this error: subprocess.call(command.split(), shell=False) AttributeError: 'NoneType' object has no attribute 'split' My guess means that its not picking up command (look at source for reference) or that its not getting command with variables. But i know the error when variables are not being picked up so i don't think it is that. My question is, from what i have thus far, how do i from "class view" grab "command" for my subprocesses to run. Thanks~ John Riselvato

  • Unresolved external symbol

    - by kriau
    I have two WIN32 DLL projects in the solution, main.dll should call a function in mgn.dll. mgn.dll has mgn.h header file: #ifdef MGN_EXPORTS #define MGN_API __declspec(dllexport) #else #define MGN_API __declspec(dllimport) #endif extern "C" bool MGN_API AttachMGN(void); and mgn.cpp source file: #include "stdafx.h" #include "mgn.h" MGN_API bool AttachMGN(void) { ... } main.dll calls AttachMGN function from one of the source file: #include "stdafx.h" #include "..\mgn\mgn.h" bool CreateClient() { return ::AttachMGN(); } mgn.dll compiles successfully. main.dll doesn't show any errors in VS text editor, I can navigate using "Go To Definition" function. However during build I get the error: error LNK2019: unresolved external symbol _imp_AttachMGN referenced in function "bool __cdecl CreateClient(void)" (?CreateClient@@AW4XZ) Both DLLs compile into the same folder. DependencyWalker shows the function AttachMGN as exported. Main project has a dependency set to Mgn project, if that matters. I believe that I simply have overlooked something.... Thanks in advance.

  • Are ASCII diagrams worth my time?

    - by Jesse Stimpson
    Are ASCII diagrams within source code worth the time they take to create? I could create a bitmap diagram much faster, but images are much more difficult to in line in a source file (until VS2010). For the record, I'm not talking about decorative ASCII art. Here's an example of a diagram I recently created for my code that I probably could have constructed in half the time in MS Paint. Scenario A: v (U)_________________(N)_______<--(P) Legend: ' / | J = ... ' / | P = ... ' /d | U = ... ' / | v = ... ' / | d = ... '/ | N = ... (J) | | | |___________________|

  • Replace token in ANTLR

    - by user1019710
    I want to replace a token using ANTLR. I tried with TokenRewriteStream and replace, but it didn't work. Any suggestions? ANTLRStringStream in = new ANTLRStringStream(source); MyLexer lexer = new MyLexer(in); TokenRewriteStream tokens = new TokenRewriteStream(lexer); for(Object obj : tokens.getTokens()) { CommonToken token = (CommonToken)obj; tokens.replace(token, "replacement"); } The lexer finds all occurences of single-line comments, and i want to replace them in the original source too.

  • A good F# codebase to learn from

    - by Lucas
    Hi all, I've been teaching myself F# for a while now. I've read Programming F# by Chris Smith (great book) and I've written a few small scripts for getting the job done here and there. But IMO the best way to learn a new programming language—and more importantly, the idioms that come with it—is to read a good open source codebase written in that language. Naturally, writing code in that language is crucial, but in the beginning, you're basically struggling with your own ignorance about how things should be done. You could perform certain tasks one way or the other, but it takes experience to realize the flaws and virtues of each. Even after you've gotten a firm grasp of how things work, reading the code of people who have an even firmer one helps a great deal. Most would agree that the most insightful parts of any learn-a-programming-language book are the code examples, and reading a well-written open source codebase is the next level of that. So are there any out there for F#?

  • How to see contents of deployed datasource?

    - by callisto
    I've inherited a project (without a handy handover) that contains reports published to a Reporting Server (2005). MY SSRS knowledge is 4 years stale, so I need your help. I need to edit one of the published reports, is this possible? I also want to peek into the Data Source on the RS, coz that's probably where I can change stuff. I'll add more info as I get a better understanding of what exactly to ask. EDIT: I found a project for some of the reports, opened up in VS2005 BI. Still, how do see where the Data Source gets its data? It brins back 56 fields but I dont know which tables/stored procs/queries are used to get these.

  • Include a Class in another model / class / lib

    - by jaycode
    I need to use function "image_path" in my lib class. I tried this (and couple of other variations): class CustomHelpers::Base include ActionView::Helpers::AssetTagHelper def self.image_url(source) abs_path = image_path(source) unless abs_path =~ /^http/ abs_path = "#{request.protocol}#{request.host_with_port}#{abs_path}" end abs_path end end But it didn't work. Am I doing it right? Another question is, how do I find the right class to include? For example if I look at this module: http://api.rubyonrails.org/classes/ActionView/Helpers/AssetTagHelper.html is there a rule of thumb how to include that module in a model / library / class / anything else ?

  • Why does cisco IOS require domain-name to be set before SSH keys can be generated?

    - by Daniel Papasian
    Is there a technical reason why IOS requires the device's domain-name to be set (via ip domain-name) before an SSH key can be generated? Is the domain-name used in any way in the generation of the key? Is there any way to force the generation of a key before the domain name is set? UPDATE: Myself (before I posted this question) and others in your answer seem to think it may be used as either a salt or a source of entropy for the key. Wouldn't the domain-name be very predictable? This doesn't seem like a suitable source of entropy.
