  • Android: Can not send http post

    - by jpartogi
    Hi all, I've been banging my head trying to figure out how to send a post method in Android. This is how my code look like: public class HomeActivity extends Activity implements OnClickListener { private TextView textView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); textView = (TextView) findViewById(R.id.text); Button button = (Button)findViewById(R.id.button); button.setOnClickListener(this); } @Override public void onClick(View view) { HttpPost httpMethod = new HttpPost("http://www.example.com/"); httpMethod.addHeader("Accept", "text/html"); httpMethod.addHeader("Content-Type", "application/xml"); AndroidHttpClient client = AndroidHttpClient.newInstance("Android"); String result = null; try { HttpResponse response = client.execute(httpMethod); textView.setText(response.toString()); HttpEntity entity = response.getEntity(); Log.i(HomeActivity.class.toString(), result); textView.setText("Invoked webservice"); } catch (IOException e) { e.printStackTrace(); Log.e(HomeActivity.class.toString(), e.getMessage()); textView.setText("Something wrong:" + e.getMessage()); } } } What am I doing wrong here? Is there anything that I may need to configure from the Android emulator to get this working? Thank you for your help.

  • Core Data + Core Animation/CALayer together??

    - by ivanTheTerrible
    I am making an Cocoa app with custom interfaces. So far I have implemented one version of the app using CALayer doing the rendering, which has been great given the hierarchical structure of CALayers, and its [hitTest:] function for handling mouse events. In this early version, the model of the app are my custom classes. However, as the program grows I feel the urge of using Core Data for the model, not just for the ease of binding/undo management, but also want to try out the new technology. My method so far: In Core Data: creating a Block entity, with attributes xPos, yPos, width, height...etc. Then, creating a BlockView : CALayer class for drawing, which uses methods such as self.position.x = [self valueForKey:@"xPos"] to fetch the values from the model. In this case, every BlockView object has to also keep a local copy of xPos, which is NOT good. Do any of you guys have better suggestions? Edit: This app is a information visualization tool. So the positions, dimensions of the blocks are important, and should be persisted for later analysis.

  • Hibernate : Opinions in Composite PK vs Surrogate PK

    - by Albert Kam
    As i understand it, whenever i use @Id and @GeneratedValue on a Long field inside JPA/Hibernate entity, i'm actually using a surrogate key, and i think this is a very nice way to define a primary key considering my not-so-good experiences in using composite primary keys, where : there are more than 1 business-value-columns combination that become a unique PK the composite pk values get duplicated across the table details cannot change the business value inside that composite PK I know hibernate can support both types of PK, but im left wondering by my previous chats with experienced colleagues where they said that composite PK is easier to deal with when doing complex SQL queries and stored procedure processes. They went on saying that when using surrogate keys will complicate things when doing joining and there are several condition when it's impossible to do some stuffs when using surrogate keys. Although im sorry i cant explain the detail here since i was not clear enough when they explain it. Maybe i'll put more details next time. Im currently trying to do a project, and want to try out surrogate keys, since it's not getting duplicated across tables, and we can change the business-column values. And when the need for some business value combination uniqueness, i can use something like : @Table(name="MY_TABLE", uniqueConstraints={ @UniqueConstraint(columnNames={"FIRST_NAME", "LAST_NAME"}) // name + lastName combination must be unique But im still in doubt because of the previous discussion about the composite key. Could you share your experiences in this matter ? Thank you !

  • A methology that allows for a single Java code base covering many different versions?

    - by Thorbjørn Ravn Andersen
    I work in a small shop where we have a LOT of legacy Cobol code and where a methology has been adopted to allow us to minimize forking and branching as much as possible. For a given release we have three levels: CORE - bottom layer, this code is common to all releases GROUP - optional code common to several customers. CUSTOMER - optional code specific for a single customer. When a program is needed, it is first searched for in CUSTOMER, then in GROUP and finally in CORE. A given application for us invokes many programs which all are looked for in this sequence (think exe files and PATH under Windows). We also have Java programs interacting with this legacy code, and as the core-group-customer lookup mehchanism does not lend it self easily to Java it has tended to grow in a CVS branch for each customer, requiring much too much maintainance. The Java part and the backend part tend to be developed in parallel. I have been assigned to figure out a way to make the two worlds meet. Essentially we want a Java enviornment which allows us to have a single code base with sources for each release, where we easily can select a group and a customer and work with the application as it goes for that customer, and then easily switch to another codeset and THAT customer. I was thinking of perhaps a scenario with an Eclipse project for each core, customer, and group and then use Project Sets to select those we need for a given scenario. The problem I cannot get my head about, is how we would create robust code in the CORE projects which will work regardless of which group and customer is selected. A Factory class which knows which sub class of a passed Class object to invoke instead of each and every new? Others must have had similar code base management problems. Anybody with experiences to share? EDIT: The conclusion to this problem above has been that CVS needs to be replaced with a source code management system better suited for dealing with many branches concurrently and the migration of source from one component to the other while keeping history. Inspired by the recent migration by slf4j and logback we are currently looking at git as it handles branches very well. We've considered subversion and mercurial too but git appears to be better for single location, multibranched projects. I've asked about Perforce in another question, but my personal inclination is towards open source solutions for something as crucial as this. EDIT: After some more pondering, we've found that our actual pain point is that we use branches in CVS, and that branches in CVS are the easiest to work with if you branch ALL files! The revised conclusion is that we can do this with CVS alone, by switching to a forest of java projects, each corresponding to one of the levels above, and use the Eclipse build paths to tie them together so each CUSTOMER version pulls in the appropriate GROUP and CORE project. We still want to switch to a better versioning system but this is so important a decision so we want to delay it as much as possible. EDIT: I now have a proof-of-concept implementation of the CORE-GROUP-CUSTOMER concept using Google Guice 2.0 - the @ImplementedBy tag is just what we need. I wonder what everybody else does? Using if's all over the place? EDIT: Now I also need this functionality for web applications. Guice was until the JSR-330 is in place. Anybody with versioning experience? EDIT: JSR-330/299 is now in place with the JEE6 reference implementation Weld based on JBoss Seam and I have reimplemented the proof-of-concept with Weld and can see that if we use @Alternative along with ... in beans.xml we can get the behaviour we desire. I.e. provide a new implementation for a given functionality in CORE without changing a bit in the CORE jars. Initial reading up on the Servlet 3.0 specification indicates that it may support the same functionality for web application resources (not code). We will now do initial testing on the real application.

  • .NET: Allow NULLS in DB fields?

    - by mark smith
    Hi there, I have the task of re-factoring an SQLServer DB.... A lot of the tables and columns "ALLOW NULLS", Is this good practice... I seem to remember the authour of CSLA.NET saying it was really bad practice to allow nulls in a DB... If this is the case, what are my alternatives? Remove all "ALLOW NULLS" from all columns.... and in numeric columns use a value of -1 for example?? I would really appreciate any input anyone has. I am currently using a Model (from entity framework) from my DB and the db columns that "ALLOW NULLS" are null ... and some of the stored procedures require that i have a default value... i.e. BOOLEAN require FALSE as default ... but it is null.. Well i don't want to stray from my original question, ALLOW NULLS are a bad thing from what i can gather .... so how do i fix this ? Any help really appreciated

  • Is there any way to optimize this LINQ where clause that searches for multiple keywords on multiple

    - by Daniel T.
    I have a LINQ query that searches for multiple keywords on multiple columns. The intention is that the user can search for multiple keywords and it will search for the keywords on every property in my Media entity. Here is a simplified example: var result = repository.GetAll<Media>().Where(x => x.Title.Contains("Apples") || x.Description.Contains("Apples") || x.Tags.Contains("Apples") || x.Title.Contains("Oranges") || x.Description.Contains("Oranges") || x.Tags.Contains("Oranges") || x.Title.Contains("Pears") || x.Description.Contains("Pears") || x.Tags.Contains("Pears") ); In other words, I want to search for the keywords Apples, Oranges, and Pears on the columns Title, Description, and Tags. The outputted SQL looks like this: SELECT * FROM Media this_ WHERE (((((((( this_.Title like '%Apples%' or this_.Description like '%Apples%') or this_.Tags like '%Apples%') or this_.Title like '%Oranges%') or this_.Description like '%Oranges%') or this_.Tags like '%Oranges%') or this_.Title like '%Pears%') or this_.Description like '%Pears%') or this_.Tags like '%Pears%') Is this the most optimal SQL in this case? If not, how do I rewrite the LINQ query to create the most optimal SQL statement? I'm using SQLite for testing and SQL Server for actual deployment.

  • Rest WebService error handling.

    - by Pratik
    Hi there, I am using RestWebservice for few basic operations , like creating/searching. The request xml looks something like this <customer> <name/> ..... </customer> For a successful operation I return the same customer XML with extra fields populated in it(eg. systemId etc which we blank in the request) . with Response.Status=2000 For an unsuccessful operation i return something like this with different error codes . e.g Response.Status = 422(Unprocessable entity) Response.Status= 500(Internal Server Error) and few others.. <errors> <error> An exception occurred while creating the customer</error> <error> blah argument is not valid.</error> </errors> Now i am not sure , whether this is the correct way of sending the errors to the client. Maybe it should be present in the header of the response. I will really appreciate any help. Thanks!

  • Cascading persist and existing object

    - by user322061
    Hello, I am working with JPA and I would like to persist an object (Action) composed of an object (Domain). There is the Action class code: @Entity(name="action") @Table(name="action") public class Action { @Id @GeneratedValue(strategy=GenerationType.IDENTITY) @Column(name="num") private int num; @OneToOne(cascade= { CascadeType.PERSIST, CascadeType.MERGE, CascadeType.REFRESH }) @JoinColumn(name="domain_num") private Domain domain; @Column(name="name") private String name; @Column(name="description") private String description; public Action() { } public Action(Domain domain, String name, String description) { super(); this.domain=domain; this.name=name; this.description=description; } public int getNum() { return num; } public Domain getDomain() { return domain; } public String getName() { return name; } public String getDescription() { return description; } } When I persist an action with a new Domain, it works. Action and Domain are persisted. But if I try to persist an Action with an existing Domain, I get this error: javax.persistence.EntityExistsException: Exception Description: Cannot persist detached object [isd.pacepersistence.common.Domain@1716286]. Class> isd.pacepersistence.common.Domain Primary Key> [8] How can I persist my Action and automatically persist a Domain if it does not exist? If it exists, how can I just persist the Action and link it with the existing Domain. Best Regards, FF

  • Programmatical Creation of NSMappingModel

    - by enchilada
    I want to programmatically (without Lightweight Migration) create a mapping model between two models that are exactly the same, except one of the entities (there are a bunch of entities) has different attributes. Let's call this entity "Person". And let's say the destination model has 1) added a new attribute called "address" 2) deleted an attribute called "eyeColor" 3) kept (i.e. not done anything with) an attribute called "name" How would you create an NSMappingModel between these models programmatically? I happen to have some explicit questions that might help me do this by myself: Q1) Do I have to create NSEntityMapping objects for all of the entities other than "Person", even if they remain unchanged? Q2) How do I deal with the "address" attribute in "Person", which is a new one being created? Should I create an NSPropertyMapping for that somehow, that turns nothing into something ("address")? Q3) How do I deal with the "name" attribute in "Person"? Do I have to create an NSPropertyMapping for that, even though it simply stays the same? Q4) For the NSEntityMapping corresponding to "Person", is not creating any NSPropertyMapping for "eyeColor" a proper way to get it deleted? Or should I create an NSPropertyMapping for "eyeColor"? If yes, how would this object be created, i.e. what would determine that its purpose is to get rid of "eyeColor"? Thank you in advance, and I apologize not being able to answer these questions myself, as the documenation really has no good example of how to create NSMappingModels programmatically. Note again that I'm not allowed to use Lightweight Migration. I must do this manually.

  • Data Binding to an object in C#

    - by Allen
    Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string MyName { get { return myName; } set { myName = value; } } public MyClass() { myName = "Allen"; } } I also created a simple form with 1 textbox and 1 button. I init'd one instance of Myclass inside the form code and built the project. Using the DataSource Wizard in Vs2008, i selected to create a data source based on object, and selected the MyClass assembly. This created a datasource entity. I changed the databinding of the textbox to this datasource; however, the expected result (that the textbox's contents would be "allen") was not achieved. Further, putting text into the textbox is not updating the name property of the object. I know i'm missing something fundamental here. At some point i should have to tie my instance of the MyClass class that i initialized inside the form code to the textbox, but that hasn't occurred. Everything i've looked at online seems to gloss over using DataBinding with an object (or i'm missing the mark entirely), so any help is great appreciated. ----Edit--- Utilizing what i learned by the answers, i looked at the code generated by Visual Studio, it had the following: this.myClassBindingSource.DataSource = typeof(BindingTest.MyClass); if i comment that out and substitute : this.myClassBindingSource.DataSource = new MyClass(); i get the expected behavior. Why is the default code generated by VS like it is? Assuming this is more correct than the method that works, how should i modify my code to work within the bounds of what VS generated?

  • Core-data: when accessing a relationship, the count method on NSSet fails

    - by lordsandwich
    I'm trying to access a relationship (one to many) programatically. My Data model contains an NSManagedEntity called language (with a two string attributes) with a relationship to an entity called WordCategory (one-to-many). I use an NSFetchRequest to get all the Language entities. that works fine. I get the valueForKey for the relationship and that works fine. I can work with its objects. However, when I try to send the message count to the NSSet that stores the WordCategory objects I get a In other words, this line works: NSLog(@"word category count %@",[[wordCategory anyObject] valueForKey:@"name"]); This one doesn't: NSLog(@"word category count %@",[wordCategory count] I get a the message: EXC_BAD_ACCESS in the debugger. Here's the rest of the code: NSManagedObjectContext *moc = [myAppDelegate managedObjectContext]; NSFetchRequest *request = [[NSFetchRequest alloc] init]; [request setEntity:[NSEntityDescription entityForName:@"Language" inManagedObjectContext:moc]]; NSError *error = nil; NSArray *results = [moc executeFetchRequest:request error: &error]; if (error) { [NSApp presentError:error]; return; } NSManagedObject *obj = [results objectAtIndex:0]; NSSet *wordCategory = [obj valueForKey:@"category"]; NSLog(@"word category count %@",[wordCategory count]); I'll appreciate any light than anybody can shed in this mystery.

  • Getter and Setter vs. Builder strategy

    - by Extrakun
    I was reading a JavaWorld's article on Getter and Setter where the basic premise is that getters expose internal content of an object, hence tightening coupling, and go on to provide examples using builder objects. I was rather leery of abolishing getter/setter but on second reading of the article, see to quite like the idea. However, sometimes I just need one cruical element of an entity class, such as the user's id and writing one whole class just to extract that cruical element seems like overkill. It also implies that for different view, a different type of importer/exporter must be implemented (or the whole data of the class to be exported out, thus resulting in waste). Usually I tend towards filtering the result of a getter - for example, if I need to output the price of a product in different currency, I would code it as: return CurrencyOutput::convertTo($product->price(), 'USD'); This is with the understanding that the raw output of a getter is not necessary the final result to be pushed onto a screen or a database. Is getter/setter really as bad as it is protrayed to be? When should one adopt a builder strategy, or a 'get the result and filter it' approach? How do you avoid having a class needing to know about every other objects if you are not using getter/setter?

  • Convert ADO.Net EF Connection String To Be SQL Azure Cloud Connection String Compatible!?

    - by Goober
    The Scenario I have written a Silverlight 3 Application that uses an SQL Server database. I'm moving the application onto the Cloud (Azure Platform). In order to do this I have had to setup my database on SQL Azure. I am using the ADO.Net Entity Framework to model my database. I have got the application running on the cloud, but I cannot get it to connect to the database. Below is the original localhost connection string, followed by the SQL Azure connection string that isn't working. The application itself runs fine, but fails when trying to retrieve data. The Original Localhost Connection String <add name="InmZenEntities" connectionString="metadata=res://*/InmZenModel.csdl|res://*/InmZenModel.ssdl|res://*/InmZenModel.msl; provider=System.Data.SqlClient; provider connection string=&quot; Data Source=localhost; Initial Catalog=InmarsatZenith; Integrated Security=True; MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> The Converted SQL Azure Connection String <add name="InmZenEntities" connectionString="metadata=res://*/InmZenModel.csdl|res://*/InmZenModel.ssdl|res://*/InmZenModel.msl; provider=System.Data.SqlClient; provider connection string=&quot; Server=tcp:MYSERVER.ctp.database.windows.net; Database=InmarsatZenith; UserID=MYUSERID;Password=MYPASSWORD; Trusted_Connection=False; MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /> The Question Anyone know if this connection string for SQL Azure is correct? Help greatly appreciated.

  • Creating queries using Criteria API (JPA 2.0)

    - by Pym
    Hello there ! I'm trying to create a query with the Criteria API from JPA 2.0, but I can't make it work. The problem is with the "between" conditionnal method. I read some documentation to know how I have to do it, but since I'm discovering JPA, I don't understand why it does not work. First, I can't see "creationDate" which should appear when I write "Transaction_." I thought it was maybe normal, since I read the metamodel was generated at runtime, so I tried to use 'Foo_.getDeclaredSingularAttribute("value")' instead of 'Foo_.value', but it still doesn't work at all. Here is my code : public List<Transaction> getTransactions(Date startDate, Date endDate) { EntityManager em = getEntityManager(); try { CriteriaBuilder cb = em.getCriteriaBuilder(); CriteriaQuery<Transaction> cq = cb.createQuery(Transaction.class); Metamodel m = em.getMetamodel(); EntityType<Transaction> Transaction_ = m.entity(Transaction.class); Root<Transaction> transaction = cq.from(Transaction.class); // Error here. cannot find symbol. symbol: variable creationDate cq.where(cb.between(transaction.get(Transaction_.creationDate), startDate, endDate)); // I also tried this: // cq.where(cb.between(Transaction_.getDeclaredSingularAttribute("creationDate"), startDate, endDate)); List<Transaction> result = em.createQuery(cq).getResultList(); return result; } finally { em.close(); } } Can someone help me to figure this out? Thanks.

  • Single Form with Multiple Dynamic Buttons

    - by John Reilly
    I've spent hours/days trying to figure this out and now I'm completely perplexed so I thought I'd give stackoverflow a try. I'm (a newb) working in Java/JSP using Eclipse hosting on Google App Engine trying to develop an app for a volunteer organization I'm a member of. Rather than embarrass myself by showing my current code I'd love just a nudge in the right direction. I have a form (which doubles as a report basically) showing "people" grouped under the "task" they are currently working on. I would like to select multiple people from multiple tasks and reassign them to another task e.g. Bill and Jane are Gardening, Jeff is Painting. I want to select Jane and Jeff (all people have an associated checkbox in the form) and re-assign them to Sweeping (which is a task on the form but has no people assigned to it yet). Ideally, the re-assignment to Sweeping would be via a Sweeping button (each task would have a dynamically-created task button) that would pass the "Sweeping" value to a servlet along with an array or list of people whose checkbox has been checked. The servlet would handle the request (creating an Assignment "object/entity" with timeStamp, personId, taskId) and then re-direct back to the form/report which would then repaint with the current tasks/people generated from the Assignments class in the datastore. All the tasks are user-defined and retrieved from the database when building the form. Ditto the people. I've been trying to keep the jsp for presentation and the servlets for the processing but I'm no purist and would just like to get unstuck. Many thanks in advance for your assistance.

  • Signals and Variables in VHDL - Problem

    - by Morano88
    I have a signal and this signal is a bitvector. The length of the bitvector depends on an input n, it is not fixed. In order to find the length, I have to do some computations. Can I define a signal after defining the variables ? It is ggiving me errors when I do that. It is working fine If I keep the signal before the variables .. but I don't want that .. the length of Z depends on the computations of the variables. What is the solution ? library IEEE; use IEEE.STD_LOGIC_1164.ALL; use IEEE.STD_LOGIC_ARITH.ALL; use IEEE.STD_LOGIC_UNSIGNED.ALL; entity BSD_Full_Comp is Generic (n:integer:=8); Port(X, Y : inout std_logic_vector(n-1 downto 0); FZ : out std_logic_vector(1 downto 0)); end BSD_Full_Comp; architecture struct of BSD_Full_Comp is Component BSD_BitComparator Port ( Ai_1 : inout STD_LOGIC; Ai_0 : inout STD_LOGIC; Bi_1 : inout STD_LOGIC; Bi_0 : inout STD_LOGIC; S1 : out STD_LOGIC; S0 : out STD_LOGIC ); END Component; Signal Z : std_logic_vector(2*n-3 downto 0); begin ass : process Variable length : integer := n; Variable pow : integer :=0 ; Variable ZS : integer :=0; begin while length /= 0 loop length := length/2; pow := pow+1; end loop; length := 2 ** pow; ZS := length - n; wait; end process; end struct;

  • Hibernate mapping - "Could not determine type"

    - by Pool
    I currently have the following objects persisting successfully: Person first name, etc. Exams title, date, etc. I'd like to now create a third table Exam results. For this table I believe it should be person ID, exam ID and result, and this is a many to many relationship. @Entity public class ExamResult { private Exam exam; private Person person; private double value; @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="EXAM_ID") public Exam getExam() { return exam; } public void setExam(Exam exam) { this.exam = exam; } @Id @ManyToOne( cascade = {CascadeType.PERSIST, CascadeType.MERGE} ) @JoinColumn(name="PERSON_ID") public Person getPerson() { return person; } public void setPerson(Person person) { this.person = person; } public double getValue() { return value; } public void setValue(double value) { this.value = value; } } The error: org.hibernate.MappingException: Could not determine type for: Person, at table: ExamResult, for columns: [org.hibernate.mapping.Column(person)] I think I may be going about this the wrong way, but I can't work out how to proceed with this relationship from the tutorial. Any ideas?

  • Programmatically modifying a file on Windows Server 2008 (Web Ed.)

    - by Tom
    I have written a .NET 2008 application, incorporating Microsoft.Office.Interop.Excel, that modifies an existing Excel 2007 spreadsheet. It works perfectly on my WinXP development computer. When I upload the app to a Microsoft Web Server 2008, it opens the file and reads from the file, but when the app tries to save the file, it throws this exception: "System.Runtime.InteropServices.COMException (0x800A03EC): 'july2009.xlsx' is read-only. To save a copy, click OK, then give the workbook a new name in the Save As dialog box." The file is NOT read-only, nor is it opened by any other user or app. The app and the Excel file both reside on the D: (data-only) drive. My first instinct was to look at file permissions. When nothing else worked, I literally created a temporary Group, added EVERY user and security entity to it and granted the group full control of the entire D: drive. No luck. Then I tried manually elevating the permission by running my app as administrator. No luck. Finally, I copied the file to my XP development computer and ran the app there. Of course it worked perfectly. Can anyone please tell me how to give my program permission to edit a file on Server 2008? Thanks!

  • Mono-LibreOffice System.TypeLoadException

    - by Marco
    In the past I wrote a C# library to work with OpenOffice and this worked fine both in Windows than under Ubuntu with Mono. Part of this library is published here as accepted answer. In these days I discovered that Ubuntu decided to move to LibreOffice, so I tried my library with LibreOffice latest stable release. While under Windows it's working perfectly, under Linux I receive this error: Unhandled Exception: System.TypeLoadException: A type load exception has occurred. [ERROR] FATAL UNHANDLED EXCEPTION: System.TypeLoadException: A type load exception has occurred. Usually Mono tells us which library can't load, so I can install correct package and everything is OK, but in this case I really don't know what's going bad. I'm using Ubuntu oneiric and my library is compiled with Framework 4.0. Under Windows I had to write this into app.config: <?xml version="1.0"?> <configuration> <startup useLegacyV2RuntimeActivationPolicy="true"> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0,Profile=Client"/> </startup> </configuration> because LibreOffice assemblies uses Framework 2.0 (I think). How can I find the reason of this error to solve it? Thanks UPDATE: Even compiling with Framework 2.0 problem (as expected) is the same. Problem (I think) is that Mono is not finding cli-uno-bridge package (installable on previous Ubuntu releases and now marked as superseded), but I cannot be sure. UPDATE 2: I created a test console application referencing cli-uno dlls on Windows (they are registered in GAC_32 and GAC_MSIL). CONSOLE app static void Main(string[] args) { Console.WriteLine("Starting"); string dir = Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location); string doc = Path.Combine(dir, "Liberatoria siti web.docx"); using (QOpenOffice.OpenOffice oo = new QOpenOffice.OpenOffice()) { if (!oo.Init()) return; oo.Load(doc, true); oo.ExportToPdf(Path.ChangeExtension(doc, ".pdf")); } } LIBRARY: using unoidl.com.sun.star.lang; using unoidl.com.sun.star.uno; using unoidl.com.sun.star.container; using unoidl.com.sun.star.frame; using unoidl.com.sun.star.beans; using unoidl.com.sun.star.view; using unoidl.com.sun.star.document; using System.Collections.Generic; using System.IO; using System; namespace QOpenOffice { class OpenOffice : IDisposable { private XComponentContext context; private XMultiServiceFactory service; private XComponentLoader component; private XComponent doc; public bool Init() { Console.WriteLine("Entering Init()"); try { context = uno.util.Bootstrap.bootstrap(); service = (XMultiServiceFactory)context.getServiceManager(); component = (XComponentLoader)service.createInstance("com.sun.star.frame.Desktop"); XNameContainer filters = (XNameContainer)service.createInstance("com.sun.star.document.FilterFactory"); return true; } catch (System.Exception ex) { Console.WriteLine(ex.Message); if (ex.InnerException != null) Console.WriteLine(ex.InnerException.Message); return false; } } } } but I'm not able to see "Starting" !!! If I comment using(...) on application, I see line on console... so I think it's something wrong in DLL. There I'm not able to see "Entering Init()" message on Init(). Behaviour is the same when LibreOffice is not installed and when it is !!! try..catch block is not executed...
