• How to do steps of an API through CLI

  - by Dolphin

  I'm using Audiveris API to generate xml(MusicXML) file once the sheetmusic(e.g. pdf/img file) is being input (i.e. When I give the sheet music (pdf file) location, to generate the xml file out of it (in another location)). Audiveris has its own GUI to do this. But can I do this process of sheetmusic-to-xml without using their GUI, but only from the CLI? If so how may I approach it? And also if so - is there a possibility to make it work in CLI - using Java code (say to invoke steps for API to occur in the CLI using Java Code)? I managed to open the GUI by opening the jar file from CLI. But I need to know whether there's a possibility to carry out the sheetmusic(say pdf)-to-xml process without using their GUI, but only through CLI? Greatly appreciate any help or guidance Thanks in advance

• UISearchDisplayController automatically creates a UIPopovercontroller to display content search result ?! How to dismiss it ?

  - by yonel

  Hi, I'm using a UISearchDisplayController with a UISearchBar. I put this UISearchBar in my app using IB and I get : Fine : when you start taping, the result popovercontroller appears magically (I didn't write anything on my own to make it appear !) Then, when a row is clicked among the result, I want to dismiss the PopoverController BUT at this stage, I never instantiated the UIPopoverController on my side : it looks like if there's an encapsulated behavior in the UISearchDisplayController that automatically wraps its searchContentsController inside a UIPopoverController. That's really great because everything works perfectly without doing anything except that I cannot get the reference to this UIPopoverController to dismiss it :( Does anyone know how to get the reference to this "magically" created UIPopoverController ? (this is the proof the iPad is really a "magical" device ;) I thought there would be a reference to the UIPopoverController from its contentController (through its parent property for instance), but I cannot find any way to get a pointer to it :/

• How to access GMAIL for storage in custom CRM SQL Server DB?

  - by Optimal Solutions

  I have a client who wants his custom-written CRM to be able to access his sales people's emails so that, effectively, a history of email conversations between customer and salesperson is stored inside the CRM's database. The CRM is written in VB 2008 and the database is SQL Server 2008. The only email these people use, in the shop and on the road, is GMAIL. Each sales person has their own GMAIL address. Thats how they operate. If they're on the road and respond to a customer's email inquiry about a product, they would like that email conversation to be stored in a table in the database. I think thats the part I cant wrap my head around. How to get access to the email data (knowing the user id and password) and doing so from VB 2008

• Set Java Application's virtual machine max memory without access to VM parameters because of custom

  - by Tom

  I'm using a Java application which allows you to import custom files. On import, these files are loaded into memory. The problem is that the files I want to import are very big, this causes an OutOfMemory exception. The crash log also informs me that the VM was started with the java parameter "-Xmx512m", I want to alter this to "-Xmx1024m" so that I got double the memory available. The problem is that this application is using it's own JRE folder and that there's a launcher written in C which is calling the jvm.dll file. In any way, java.exe or javaw.exe are never called and thus I cannot set these parameters myself (if I delete these executables it doesn't matter, can still run the application - this is not the case with the dll). So, my question is, can I set this VM parameter in an other way? I'm even willing to alter the JRE files if there is no other way.

• A resource for installation or setup folder hierarchy of various applications

  - by Luay

  Is there a web site (or something else) that has information on folders and their hierarchy where various programs and applications are installed? Please let me explain. I am writing an application that (part of what it does) references certain files installed by other application. To be able to determine the file paths for these folders I have to download and install each application seperatly on my development pc, search for the file I want, and then write its path in my application. This method is very time consuming and, frankly, boring, as it requires downloading and installing each application (some of them in excess of 600MB) and then locating the required file just to be able to "know" its path. So, I was wondering if there is something that could speed things up. like, for example, a website that would have such information. I tried each of the applications own website for information but no dice. Any help from you will be much appreciated. Many thanks

• Can I embed video on external sites while still using tokens to protect the content?

  - by JKS

  On our own website, it's easy to protect against direct links to our video content by grabbing a token through AJAX and verifying the token through PHP before the file download is started. However I'm also researching how I could provide an embed feature, like YouTube or vimeo etc., without compromising this security feature. The problem is that the embed code I want to provide should look something like <object>...<embed>...</embed></object> -- but I don't know how to grab and append the token to the filename. I mean, I guess I could attach a script that did some gnarly JNOP business, but that's too dirty. I'm using JW Player for the actual video container. Huge thanks to anyone who can help...

• Genetic programming in c++, library suggestions?

  - by shuttle87

  I'm looking to add some genetic algorithms to an Operations research project I have been involved in. Currently we have a program that aids in optimizing some scheduling and we want to add in some heuristics in the form of genetic algorithms. Are there any good libraries for generic genetic programming/algorithms in c++? Or would you recommend I just code my own? I should add that while I am not new to c++ I am fairly new to doing this sort of mathematical optimization work in c++ as the group I worked with previously had tended to use a proprietary optimization package. We have a fitness function that is fairly computationally intensive to evaluate and we have a cluster to run this on so parallelized code is highly desirable. So is c++ a good language for this? If not please recommend some other ones as I am willing to learn another language if it makes life easier. thanks!

• Maven: Multiple class with the same path implemented in different jar

  - by Phuong Nguyen de ManCity fan

  I'm running into trouble with having multiple class with the same path (i.e. same name, same package!!!). For some reason, gwt-dev comes with its own version of org.apache.xerces.jaxp.DocumentBuilderFactoryImpl and javax.xml.parsers.DocumentBuilderFactory. At the same time, spring also depends on these classes but from different jar. I don't know what should be, but look like xalan & xml-api are the two dependencies that spring depends on (these dependency are optional) Funny thing is that eclipse can run the same code (it's a unit test) without problem, but surefire cannot. So I guess the problem is due to the way each runner consider the priority of each jar. Now come to the question: How can I setup my POM so that I can sure that when ever any code running inside my app, then class from a jar will be selected over class from other jar? Thanks.

• design using a readonly class in c#

  - by edosoft

  Hi Small design question here. I'm trying to develop a calculation app in C#. I have a class, let's call it InputRecord, which holds 100s of fields (multi dimensional arrays) This InputRecordclass will be used in a number of CalculationEngines. Each CalculcationEngine can make changes to a number of fields in the InputRecord. These changes are steps needed for it's calculation. Now I don't want the local changes made to the InputRecord to be used in other CalculcationEngine's classes. The first solution that comes to mind is using a struct: these are value types. However I'd like to use inheritance: each CalculationEngine needs a few fields only relevant to that engine: it's has it's own InputRecord, based on BaseInputRecord. Can anyone point me to a design that will help me accomplish this?

• PHP, MVC, 404 - How can I redirect to 404?

  - by Doug

  I'm trying to build my own MVC as a practice and learning experience. So far, this is what I have: <?php require "config.php"; $page = $_GET['page']; if( isset( $page ) ) { echo "isset is true"; if( file_exists( MVCROOT . "/$page.php" ) ) { include "$page.php"; } else { header("HTTP/1.0 404 Not Found"); } } ?> My problem here is, I can't use header to send to a 404 because the headers have been send already. Should I just redirect to a 404.html or is there a better way? Feel free to critique what I have so far (it's very little). I would love suggestions and ideas. Thanks!

• Is there a pattern that allows a constructor to be called only from a specific factory and from nowh

  - by willem

  We have a class, say LegacyUserSettingsService. LegacyUserSettingsService implements an interface, IUserSettingsService. You can get an instance of the IUserSettingsService by calling our ApplicationServicesFactory. The factory uses Spring.NET to construct the concrete LegacyUserSettingsService. The trouble is that new developers sometimes do their own thing and construct new instances of the LegacyUserSettingsService directly (instead of going via the factory). Is there a way to protect the constructor of the concrete class so it can only be called from the factory? A well-known pattern perhaps? Note that the concrete class resides in a different assembly (separate from the Factory's assembly, so the internal keyword is not a solution). The factory assembly references the other assembly that contains the concrete class. Any ideas?

• oracle plsql: retrieve runtime parameter values when you call a procedure

  - by Luca Vaccaro

  I need a generalized method to get list of runtime parameters (values) when I call a procedure. I need something similar to the $$PLSQL_UNIT that returns the name of the running procedure. (plsql Oracle 10g) E.g. look at this sample procedure: (it simply prints its own name and parameters ) CREATE OR REPLACE PROCEDURE MY_PROC(ow in varchar2, tn IN varchar2) IS BEGIN dbms_output.put_line('proc_name: '||$$PLSQL_UNIT||' parameters: '|| ow||' '||tn ); EXCEPTION WHEN OTHERS THEN DBMS_OUTPUT.PUT_LINE('ERRORE: ' ||SQLERRM); END MY_PROC; / Running procedure produces the following output: SQL> 1 BEGIN 2 IBAD_OWN.MY_PROC('first_par', 'second_par'); 3 END; 4 / proc_name: MY_PROC parameters: first_par second_par PL/SQL procedure successfully completed. I'm not satisfy because I can't copy and paste in all my procedures because I have to hard code each procedure to set their right parameter variables. Thanks in advance for the help.

• Tabcompletion and docview while editing rc.lua

  - by Berxue

  I saw that there is a lua plugin for eclipse and there is a docpage on the awesome main page api_doc and all the .lua files in /usr/share/awesome/lib. So I thought it must be possible to create a Library or Execution Environment so that one has tabcompletion and docview. So I tried making my own Execution Environment: wrote the standard .rockspec file downloaded the documentation made an ofline version of it and put it in docs/ folder ziped the files and folders in /usr/share/awesome/lib ziped all up tried it out ... and it failed. When I try to view a documentaion for a .lua file I get "Note: This element has no attached documentation." Questions: Am I totaly wrong in my doing (because I have the feeling I am)? Is there any way to edit the rc.lua with tabcompletion and docview?

• Drupal. Use AJAX to update view's content

  - by ozke

  Hi, I've created a view in Drupal that retrieves a list of nodes. The display of this view is a page and it works perfectly well. It does even allow me to filter its content by argument. See the current's view configuration (click to enlarge): I want to use AJAX to use the filter (by parameter) functionality without reloading the page. I've enabled the "Use AJAX" option but I am not sure on how to continue. Any ideas on how to do that? By the way, I'm building my own theme (in case that changes anything). Thanks in advance Update: Basically, this view works when I browse through section/parameter1, section/parameter2... but I want to do the same with AJAX, without reloading the page. I hope is clearer now

• Is there a non-blocking version of MessageBox.Show (or something like it)?

  - by Dan Tao

  Often you just want to notify the user that something has occurred, but there's really no need for any input from them. In this common scenario, I sometimes see code like this: MessageBox.Show("Something has occurred", "Something", MessageBoxButtons.OK); This code, as we all know, causes a little pop-up window to appear with only an OK button. Now here's the thing: this code blocks (the UI thread). But in the vast majority of cases, it seems to me, if you only have an OK button, there's very little need to block. (Isn't the purpose of blocking typically to receive some input from the user? And if the user's only choice is "OK," in this typical case, isn't blocking pretty pointless?) Obviously I could just write my own little form that does basically exactly what MessageBox.Show does, except that it returns nothing (no DialogResult) and doesn't block. But I was just wondering if something like this exists already that I didn't know about.

• Emacs cheat sheet that lists equivalents to everyday vim commands

  - by Yktula

  There were two things that I want to know how to do in Emacs (23.2, *nix): Go to the first character after indentation in a line Go to the first character that's the equivalent to a given character (an equivalent to vim's fx command that goes forward until it hits the x character; maybe C-s (incremental search) is the best way to do this) But, I think it would be better if I had a cheat sheet that listed navigational bindings. Maybe Emacs (self-documenting) can do this on it's own. Is there a list of commands that are equivalent to vim's default commands anywhere? How about a list of navigational key-bindings in Emacs?

• SharePoint Client JavaScript Documentation

  - by G N

  I'm attempting to improve the usability of a client's SharePoint deployment via JQuery; and am hitting a brick wall when trying to find any sort of documentation of what's happening in core.js (aside from painfully digging through and trying to parse any sort of meaning out of it --all 250kb of it!!!!--) Anyone have any pointers, or documentation? EDIT: Sorry, to clarify my question, i'm familiar with using JQuery with SharePoint. My question involves hooking JQuery into SharePoint's own client API. My question is inspired by this post http://www.codefornuts.com/2009/09/forcing-sharepoint-into-asynchronous.html# ; where the author is overriding methods such as "SubmitFormPost" and "STSNavigate" in order to make the UI interaction more "AJAXy".

• What's the best way to apply a drop shadow?

  - by jckeyes

  What is the best method for applying drop shadows? I'm working on a site right now where we have a good deal of them, however, I've been fighting to find the best method to do it. The site is pretty animation heavy so shadows need to work well with this. I tried a jQuery shadow pulgin. The shadows looked good and were easy to use but were slow and didn't work well with any animations (required lots of redrawing, very joggy). I also tried creating my own jQuery extension that wraps my element in a couple gray divs and then offsets them a little bit to give a shadow effect. This worked well. It's quick and responsive to the animation. However, it makes DOM manipulation/traversal cumbersome since everything is wrapped in these shadow divs. I know there has to be a better way but this isn't exactly my forte. Thoughts?

• Trying to get simple jquery animations on a site I created in Dreamweaver

  - by JoeOzz

  Hey guys, another question. I'm trying to do some basic jQuery stuff for my final project. I'll be using it to modify my already existing site created in Dreamweaver a few months ago. However, no matter how I source the framework, it just won't take regardless of whether I host my own copy or link to someone else's like Google's. I'm including my jQuery function calls within my already existing .js file that includes some auto generated functions. I also tried creating a new .js specifically for my jQuery functions and still nothing. I realize this is vague, but any tips? Do I need another framework for jQuery to work off of to make animations like .fadeIn() or .slideDown()? Thanks guys and gals!

• WPF - Listbox bound to collection acts as one item

  - by user553765

  Hi, I have a listbox with the ItemsControl binding the ItemsSource to a readonly collection of strings. The ItemTemplate then declares the DataTemplate as a checkbox where its content is that of the name of the particular item in the collection and IsChecked bound to a property to determine whether or not the item is selected (it's just a listbox of checkboxes) This works fine with one exception - MouseOver the ListBox and it acts as if the collection of Strings is a single item; the whole box acts as if selected. This wouldn't be as much of a problem were it not for this also affecting the scrollbars where they won't get enabled - presumably because it considers the one item as being visible on the screen even though it in actual facts is x+ with only x-y showing on the screen. How do I get the listbox to act as if each individual string is its own item. I assume it acts this way because I declared a datatemplate in order to get a listbox of checkboxes?? Any help would be much appreciated!

• AnkhSVN - How to remove old URLs from list of URLs in the "Open from Subversion" dialog box

  - by user2942597

  I work for a small company and am the sole developer using AnkhSVN to version my code. For the server side I am using VisualSVN v2.5.8. The server is installed on my own machine (on a different drive). I have a few repositories that I created about two years ago that have been working fine. We recently completed an Active Directory Domain Rename (that's another story) so the FQDN of my machine changed so the domain portion is no longer the same as what it was when the server portion was installed. I managed to get AnkhSVN to connect to the repositories so everything is working again but the URL list that comes up on the "Open from Subversion" dialog box still has all the old URLs. How can I remove them? I've searched everywhere I can think of looking for this list but can't seem to find it anywhere. Any suggestions would be greatly appreciated. Chuck R.

• Importing ctype; embedding python in C++ application

  - by Drew

  I'm trying to embed python within a C++ based programming language (CCL: The compuatational control language, not that any of you have heard of it). Thus, I don't really have a "main" function to make calls from. I have made a test .cc program with a main, and when I compile it and run it, I am able to import my own python modules and system modules for use. When I embed my code in my CCL-based program and compile it (with g++), it seems I have most functionality, but I get the import error: ImportError: /usr/lib/python2.6/lib-dynload/_ctypes.so: undefined symbol: PyType_GenericNew Can someone explain this to me and how to go about solving it? It seems like I've linked the objects correctly. Thanks.

• Python - werid behavior

  - by orokusaki

  I've done what I shouldn't have done and written 4 modules (6 hours or so) without running any tests along the way. I have a method inside of /mydir/__init__.py called get_hash(), and a class inside of /mydir/utils.py called SpamClass. /mydir/utils.py imports get_hash() from /mydir/__init__. /mydir/__init__.py imports SpamClass from /mydir/utils.py. Both the class and the method work fine on their own but for some reason if I try to import /mydir/, I get an import error saying "Cannot import name get_hash" from /mydir/__init__.py. The only stack trace is the line saying that __init__.py imported SpamClass. The next line is where the error occurs in in SpamClass when trying to import get_hash. Why is this?

• Developing for mobile devices and desktop

  - by Augusto

  Hi, I'm starting a new project. It will run on devices running Windows CE, Windows Mobile 6 and will also have a desktop version. The software will connect to some equipments through the serial port, using it's own protocol. Basically it will: connect to the equipment send and receive info read and write binary files These tasks will be shared between desktop and mobile devices. I've been searching the information I need, but I still have some doubts: If I target Windows CE devices it will work with Windows Mobile 6 too? Creating a class library targeting Windows CE will give me any trouble on using it in the desktop version? (when I add a reference to that class library, my VS says that I could experience some unexpected results) Is it possible to install .NET CF 3.5 on devices running Windows CE 4.2? Thanks!
