How to improve performance of opening Microsoft Word when automated from c#?

- by Abdullah BaMusa

I have Microsoft Word template that I automated filling it’s fields from my application, and when the user request print I open this template. but creating word application every time user request print after filling fields is very expensive and lead to some delay while opening the template, so I choose to cache the reference to Word then just open the new filled template. that solve the performance issue as opening file is less expensive than recreating Word each time, but this work while the user just close the document not the entire Word application which when happened my reference to Word become invalid and return with exception says: “The RPC server is unavailable” next time request opening template . I tried to subscribe to BeforClosing event but his trigger for Quitting Word as well as Closing documents. My question is how to know if the word is closing document or quit the entire application so I take the proper action, or any hint for another direction of thinking about improve performance of opening word template.

How to include named capture groups in java regex?

- by jrummell

I'm new to regex in Java and I can't figure out how to include named capture groups in an expression. I'm writing a ScrewTurn Image Converter for Confluence's Universal Wiki Converter. This is what I have: String image = "\\[image(?<align>auto)?\\|\\|{UP\\(((?<namespace>\\w+)\\.)?(?<pagename>[\\w-]+)\\)}(?<filename>[\\w- ]+\\.[\\w]+)\\]"; Pattern imagePattern = Pattern.compile(image, Pattern.CASE_INSENSITIVE); It's throwing this exception in Pattern.comiple(): java.util.regex.PatternSyntaxException: Unknown look-behind group near index 19 \[image(?<align>auto)?\|\|{UP\(((?<namespace>\w+)\.)?(?<pagename>[\w-]+)\)}(?<filename>[\w- ]+\.[\w]+)\] ^ I've used named capture groups like this before in C# (?<namedgroup>asdf), but not in Java. What am I missing?

Grails: Duplicates & unique constraint validation

- by rukoche

OK here is stripped down version of what I have in my app Artist domain: class Artist { String name Date lastMined def artistService static transients = ['artistService'] static hasMany = [events: Event] static constraints = { name(unique: true) lastMined(nullable: true) } def mine() { artistService.mine(this) } } Event domain: class Event { String name String details String country String town String place String url String date static belongsTo = [Artist] static hasMany = [artists: Artist] static constraints = { name(unique: true) url(unique: true) } } ArtistService: class ArtistService { def results = [ [ name:"name", details:"details", country:"country", town:"town", place:"place", url:"url", date:"date" ] ] def mine(Artist artist) { results << results[0] // now we have a duplicate results.each { def event = new Event(it) if (event.validate()) { if (artist.events.find{ it.name == event.name }) { log.info "grrr! valid duplicate name: ${event.name}" } artist.addToEvents(event) } } artist.lastMined = new Date() if (artist.events) { artist.save(flush: true) } } } In theory event.validate() should return false and event will not be added to artist, but it doesn't.. which results in DB exception on artist.save() Although I noticed that if duplicate event is persisted first everything works as intended. Is it bug or feature? :P

android detect is gyroscope available

- by Tan Jit Ren

How can I detect whether the android device has gyroscope? Currently I'm using the following method to detect whether gyroscope is available. If gyroscope not available, then use accelerometer. SensorManager mgr = (SensorManager) getSystemService(SENSOR_SERVICE); List<Sensor> sensors = mgr.getSensorList(Sensor.TYPE_ALL); for (Sensor sensor : sensors) { Log.i("sensors",sensor.getName()); if(sensor.getName().contains("Gyroscope")){ try{ mSensorManager.registerListener(this, mSensorManager.getDefaultSensor(Sensor.TYPE_ROTATION_VECTOR), SensorManager.SENSOR_DELAY_FASTEST); return; }catch(Exception e){ } } } mSensorManager.registerListener(this, mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST); However some of my app users complaint they can't use gyroscope. Is there any problem with the code?

How to find the entity with the greatest primary key?

- by simpatico

I've an entity LearningUnit that has an int primary key. Actually, it has nothing more. Entity Concept has the following relationship with it: @ManyToOne @Size(min=1,max=7) private LearningUnit learningUnit; In a constructor of Concept I need to retrieve the LearningUnit with the greatest primary key. If no LearningUnit exists yet I instantiate one. I then set this.learningUnit to the retrieved/instantied. Finally, I call the empty constructor of Concept in a try-catch block, to have the entitymanager do the cardinality check. If an exception is thrown (I expect one in the case that already another 7 Concepts are referring to the same LearningUnit. In that case, I case instantiate a new LearningUnit with a new greater primary key. Please, also point out, if any, clear pitfalls in my outlined algorithm above.

Java blocking socket returning incomplete ByteBuffer

- by evandro-carrenho

I have a socketChannel configured as blocking, but when reading byte buffers of 5K from this socket, I get an incomplete buffer sometimes. ByteBuffer messageBody = ByteBuffer.allocate(5*1024); messageBody.mark(); messageBody.order(ByteOrder.BIG_ENDIAN); int msgByteCount = channel.read(messageBody); Ocasionally, messageBody is not completely filled and channel.read() does not return -1 or an exception, but the actual number of bytes read (which is less than 5k). Has anyone experienced a similar problem?

How to stop an activity with GL view. Application not responding

- by David

I have an activity that I want to programmatically stop after some elapsed time. I have a GL view running. My understanding is that the GLSurfaceView.renderer is running in its own thread, so I created a handler instantiated from the activity. In the GLSurfaceView I post a message. The handler then attempts to stop the activity with the following: onStop(); finish(); The activity seems to close. However, if I try to restart the application, I get a blank screen, the phone is practically locked up and eventually I get a message that the activity in the application is not responding. I'm also getting geting a wake lock, ie PowerManager.newWakeLock(...). When I try to release it, I get an exception. Not sure if its the GL view of the wake lock which is causing me troubles. Any ideas appreciated.

problem loading resource from class library

- by mishal153

I have a class library (mylibrary) which has a resource called "close.png". I used redGate reflector to confirm that the resource is actually present in the dll. Now i use mylibrary.dll in a project where i attempt to extract this "close.png" resource like this : BitmapImage crossImage = new BitmapImage(); crossImage.BeginInit(); crossImage.UriSource = new Uri(@"/mylibrary;component/Resources/close.png", UriKind.RelativeOrAbsolute); crossImage.EndInit(); This BitmapImage crossImage is then used like : Button closeButton = new Button() { Content = new System.Windows.Controls.Image() { Source = crossImage }, MaxWidth = 20, MaxHeight = 20 }; On doing this i get no exceptions being thrown but the button shows no image. Also, i do see some exception info if i investigate the button's 'content' in the debugger.

Changing gmail Settings with Ruby

- by Technocrat

I need to configure my gmail account(s) programmatically with Ruby. I checked out the apps api and it looks like the simplest possible solution would be to use ClientLogin for logging in and a simple XML PUT for changing the forwarding setting, for example. I wrote a little test script like so: http://gist.github.com/373457 It would appear that the call to ClientLogin works because it comes back with an Auth= token. When it sends the PUT request to google, however, it comes back with a RestClient::Unauthorized exception. I rewrote the script with pure net/https and it turns out the message I'm getting is invalid token, yet I can't figure out what is wrong with my token. Can anyone else see it?

Android sending SOAP object over Https via ksoap2 2.5.8

- by Jack-V

My first time posting a question here so please do not mind my mistakes here. I'm currently making an android application fetching and sending information from a .asmx web service. Everything goes well with the ksoap2 library and am using HttpTransportSE to call the web service. So now what I'm trying to do is to use the HttpsTransportSE to call the web service over Https. I got java.security.cert.certpathvalidatorexception trustanchor for certpath not found exception. I have the server certificate in .pfx , .jks and .bks format. My questions is what do i do with it to make my HttpsTransportSE call to be success? I've read around with articles using custom SSLSocketFactory but am still not sure how to implement it in my application. Thanks in advance for any suggestion/advices

RemoteWebDriver InternetExplorer navigate().to() timeout?

- by the qwerty

i was running a test remotely on internet explorer, and when using navigate().to() selenium returns me this: "12:13:58.770 INFO - WebDriver remote server: Exception: The driver reported that the command timed out. There may be several reasons for this. Check that the destinationsite is in IE's 'Trusted Sites' (accessed from Tools-Internet Options in the 'Security' tab) If it is a trusted site, then the request may have taken more thana minute to finish." i've done what's said. but when looking at the browsers the page is loaded, but still this message continues. i've already tried as simon told me: "(16:32:54) simonstewart: ponto: http://code.google.com/p/selenium/wiki/FrequentlyAskedQuestions#Q:_The_does_not_work_well_on_Vista._How_do_I_get_it_to_work_as_e " but did not solve. could it be google analytics that on the background is getting data or something like that? ps: i ran the test on firefox and it works well. i've tried on Windows 7 and Windows XP, and Internet Explorer 7 and Internet Explorer 8.

Function chaining depending on boolean result

- by Markive

This is just an efficiency question really.. I'm interested to know if there is a more efficient or logical way that people use to handle this sort of scenario. In my asp.net application I am running a script to generate a new project my code at the top level looks like this: Dim ok As Boolean = True ok = createFolderStructure() If ok Then ok = createMDB() If ok Then ok = createProjectConfig() If ok Then ok = updateCompanyConfig() I create a boolean and each function returns a boolean result, the next function in this chain will only run if the previous one was successful. I do this because an asp.net application will continue to run through the page life cycle unless there is an unhandled exception and I don't want my whole application to be screwed up if something in the chain goes wrong (there is a lot of copying and deleting of files etc.. in this example). I was just wondering how other people handle this scenario? the vb.net single line if statement is quite succinct but I'm wondering if there is a better way?

Can I correctly debug assemblies loaded with the 'AssemblyResolve' event?

- by Thiado de Arruda

I'm experimenting with the AppDomain's 'AssemblyResolve' event by hidding the depedencies for an executable file in another folder. The assemblies seem to beloading and executing fine, however debugging seems to be crazy, sometimes it hits my break points, sometimes it doesnt , and sometimes it hits the same code twice(It seems absurd but I'm sure the code is executing only once). I don't understanding how debuggers works but I guess it has something to do with the PDB files. Anyone got an idea of what might be happening and how can I fix it? Edit: Let me add that I'm calling methods on the dynamically loaded assemblies using reflection, sometimes the method I'm stepping over throws an exception that only pops at a later time.

Behavior of nested finally in Exceptions

- by kuriouscoder

Hello: Today at work, I had to review a code snippet that looks similar to this mock example. package test; import java.io.IOException; import org.apache.log4j.Logger; public class ExceptionTester { public static Logger logger = Logger.getLogger(ExceptionTester.class); public void test() throws IOException { new IOException(); } public static void main(String[] args) { ExceptionTester comparator = new ExceptionTester(); try { try { comparator.test(); } finally { System.out.println("Finally 1"); } } catch(IOException ex) { logger.error("Exception happened" ex); // also close opened resources } System.out.println("Exiting out of the program"); } } It's printing the following output.I expected an compile error since the inner try did not have a catch block. Finally 1 Exiting out of the program I do not understand why IOException is caught by the outer catch block. I would appreciate if anyone can explain this, especially by citing stack unwinding process

Json Object to a Multidimensional C# Array?

- by Nick Brooks

Is there a way to convert a Json Object to a Multidimensional C# Array? I know it might be impractical but I can't be bothered to write classes and then deserialize the strings into them. List<string> ohyeah = (List<string>)JsonConvert.DeserializeObject(g.CommToken); That returns an Invalid Cast exception! Example: {"method":"getCommunicationToken","header":{"uuid":"9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7","clientRevision":"20100323.02","session":"c0d3e8b5d661f74c68ad72af17aeb5a1","client":"gslite"},"parameters":{"secretKey":"d9b687fa10c927f102cde9c085f9377f"}} I need to get something like that : j["method"]; //This will equal to getCommunicationToken j["header"]["uuid"]; //This will equal to 9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7 I literally need to parse the json object into an array.

Anonymous iterator blocks in Clojure?

- by Checkers

I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of anonymous iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?
