  • Is there a c++ library that provides functionality to execute an external program and read its outpu

    - by BD at Rivenhill
    Basically, I'm looking for something that will allow me to replicate the following Perl code: my $fh = new FileHandle; $fh->open("foo |"); while (<$fh>) { # Do something with this line of data. } This is in the context of Linux, so a library that is specific to Windows will not help. I know how to write a program that does fork/exec/dup2 and all that basic shell-type jazz, but there are some fiddly details involving terminals that I don't feel like messing around with (and I don't have a copy of "Advanced Programming in the UNIX Environment" or a similar reference handy), so I'm hoping that someone has already solved this problem.

  • Arguments to convince to switch from CVS to SVN

    - by ereOn
    Hi, The UNIX department of my company currently uses CVS as source-version control system. They use it in a very strange way: different repositories for development/testing/production code (for the same project), no one tags anything, weird directory architecture, and so on. The system has been set for ages but now, I have an opportunity to organize a meeting where I have to suggest changes. I'd like to make them change from CVS to SVN (Mercurial or Git might be even better, however I can't really recommand using a system I don't know well, and switching to SVN will already be a great step forward). I don't have much experience with CVS so I can't compare them efficiently: I just know it doesn't support atomic operations and that it is deprecated. What killer arguments would you use to convince my collegues to do the switch ? Thank you very much.

  • How do I determine if Android can handle PDF

    - by jasonshah
    Hi all, I know Android cannot handle PDFs natively. However, the Nexus One (and possibly other phones) come pre-installed with QuickOffice Viewer. How would I determine whether the user has a PDF viewer installed? Currently, the code to start the PDF download looks pretty simple: Intent intent = new Intent(Intent.ACTION_VIEW); intent.setData(Uri.parse(url)); startActivity(intent); After download, the user clicks on the downloaded file to invoke the viewer. However, if there is no PDF viewer, Android reports "Cannot download. The content is not supported on the phone." I want to determine if the user will get this message, and if so, direct them to PDF apps in the Android Market. Thanks!

  • Intercept close Popup from Parent Page

    - by sangi
    Hi all, I have a question. In an html page, I have javascript code that allows me to open and close a popup window by clicking on a link displayed in the link, so the text displayed in the link changes to the state of the popup window (open-closed). With a variable true / false I manage the opening and closing of the popup window to click on a link whose text is aligned "opened popup" / "closed popup". The next step is to make this same change in state (true / false, "opened popup" / "close popup") directly by closing the popup window. The idea is to not have to refresh the page. Is this possible? Thank you and best regards

  • Highlight row of form when input is focussed

    - by Jeepstone
    I have the following piece of Mootools 1.11 code (not upgradable as this is within Joomla), which I want to highlight the form row, when an item within it is focussed. However, this doesn't work. I need to know how to access the parent div of the form item. window.addEvent('domready', function() { var list = $$('#ChronoContact_lensorder div.formrow'); list.each(function(element) { var fx = new Fx.Styles(element, {duration:200, wait:false}); element.addEvent('focus', function(){ fx.start({ 'background-color': '#e6f0f2', color: '#FFF' }); }); element.addEvent('focus', function(){ fx.start({ 'background-color': '#FFF', 'color': '#2F9AD0' }); }); }); }); HTML is: <div class="formrow"> <label for="ud">Uncut Diameter:</label> <input type="text" id="ud" name="ud" /> </div> Thanks

  • Django - how to make ImageField/FileField optional?

    - by ilya
    class Product(models.Model): ... image = models.ImageField(upload_to = generate_filename, blank = True) When I use ImageField (blank=True) and do not select image into admin form, exception occures. In django code you can see this: class FieldFile(File): .... def _require_file(self): if not self: raise ValueError("The '%s' attribute has no file associated with it." % self.field.name) def _get_file(self): self._require_file() ... Django trac has ticket #13327 about this problem, but seems it can't be fixed soon. How to make these field optional?

  • Erlang Edoc in Emacs

    - by Roberto Aloi
    Let's say that I have an Erlang function, with spec. -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. My dream would be to generate the edoc from this information within Emacs automatically. The generated code should look like: %%-------------------------------------------------------------------- %% @doc %% Your description goes here %% @spec foo(_Integer::integer(), _String::string()) -> %%% boolean() %% @end %%-------------------------------------------------------------------- -spec foo(integer(), string()) -> boolean(). foo(_Integer, _String) -> true. Does a similar feature already exist?

  • InetAddress.getLocalHost() throws UnknownHostException

    - by jhwist
    Hi, I am testing our server-application (written Java) on different operating systems and thought that OpenSolaris (2008.11) would be the least troublesome due to the nice Java integration. Turns out I was wrong, as I end up with a UnknownHostException try { computerName = InetAddress.getLocalHost().getHostName(); if (computerName.indexOf(".") > -1) computerName = computerName.substring(0, computerName.indexOf(".")).toUpperCase(); } catch (UnknownHostException e) { e.printStackTrace(); } The output is: java.net.UnknownHostException: desvearth01: desvearth01 at java.net.InetAddress.getLocalHost(InetAddress.java:1353) However, nslookup desvearth01 returns the correct IP address, and nslookup localhost returns 127.0.0.1 as expected. Also, the same code works perfectly on FreeBSD. Is there anything special to OpenSolaris that I am not aware of? Any hints appreciated, thanks.

  • Is there a way to make an executable from an Xcode project?

    - by Questor
    Hello, all! I feel it's quite a naive question I'm going to ask. Excuse me if it's foolish. I have made an iPhone game using Cocos2d, Box2d and OpenGL. I want to show the game to a potential employer for demonstration purposes, without giving him the source code. How can I make a .exe or .app file from the Xcode project? I've searched online a lot but couldn't find the relevant answer. Thank you very much in advance.

  • Group and count in Rails

    - by alamodey
    I have this bit of code and I get an empty object. @results = PollRoles.find( :all, :select => 'option_id, count(*) count', :group => 'option_id', :conditions => ["poll_id = ?", @poll.id]) Is this the correct way of writing the query? I want a collection of records that have an option id and the number of times that option id is found in the PollRoles model. EDIT: This is how I''m iterating through the results: <% @results.each do |result| %> <% @option = Option.find_by_id(result.option_id) %> <%= @option.question %> <%= result.count %> <% end %>

  • Show transparent color filter on a View after clicking it

    - by Maarten
    So. You know how when you click a post in the Google+ app, the entire View becomes blue. I want to do that as well, but with an ImageView. I have the following code snippet, setting the actual image as the background and the selector as the main resource. This looks good, but doesn't respect scaleType for the background image: <ImageView android:id="@+id/painting_image" android:layout_width="match_parent" android:layout_height="200dp" android:background="@drawable/img" android:src="@drawable/selector" android:scaleType="centerCrop" /> By the way, @drawable/selector is just a selector that shows a tranparent color for state_pressed: <item android:state_pressed="true"> <shape xmlns:android="http://schemas.android.com/apk/res/android"> <solid android:color="#44521400" /> </shape></item> How can I make this work while respecting the scaleType?

  • Can't remove first node in linked list

    - by carlmonday
    I'm trying to make a linked list class in python (pointless I know, but it's a learning exercise), and the method I have written to remove a node doesn't work if I try to remove the first element of the linked list. If the node to be removed is anywhere else in the linked list the method works fine. Can someone give me some insight as to where I've gone wrong? Here's my code thus far: class Node: def __init__(self, data=None, next=None): self.data = data self.next = next def __repr__(self): return repr(self.data) def printNodes(self): while self: print self.data self = self.next def removeNode(self, datum): """removes node from linked list""" if self.data == datum: return self.next while self.next: if self.next.data == datum: self.next = self.next.next return self self = self.next

  • Retrieving content of a txt file from URL to Android

    - by eightx2
    I would like to be able to retrieve contents of a .txt file from the internet, and load it in an EditText. I tried using the code on this page: Reading Text File From Server on Android It didn't work, as you might have guessed. I've read on numerous sites about this type of problem, but I can't get anything to work. Someone suggested AndroidHttpClient (http://developer.android.com/reference/android/net/http/AndroidHttpClient.html), but I simply can't find any examples with this. As I'm a newbie in Android programming, I would love if someone could please give me a small example.

  • Why does DateTime to Unix time use a double instead of an integer?

    - by Earlz
    I'm needing to convert a DateTime to a Unix timestamp. So I googled it looking for some example code In just about all the results I see, they use double as the return for such a function, even when explicitly using floor to convert it to an integer. Unix timestamps are always integers. So what problem is there with using either long or int instead of double? static double ConvertToUnixTimestamp(DateTime date) { DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0); TimeSpan diff = date - origin; return Math.Floor(diff.TotalSeconds); }

  • How to fetch managed objects sorted by calculated value

    - by Marcin Zbijowski
    Hello, I'm working on the app that uses CoreData. There is location entity that holds latitude and longitude values. I'd like to fetch those entities sorted by distance to the user's location. I tried to set sort descriptor to distance formula sqrt ((x1 - x2)^2 + (y1 - y2)^2) but it fails with exception "... keypath ... not found in entity". NSString *distanceFormula = [NSString stringWithFormat:@"sqrt(((latitude - %f) * (latitude - %f)) + ((longitude - %f) * (longitude - %f)))", location.coordinate.latitude, location.coordinate.latitude, location.coordinate.longitude, location.coordinate.longitude]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:distanceFormula ascending:YES]; [fetchRequest setSortDescriptors:[NSArray arrayWithObject:sortDescriptor]]; NSError *error; NSArray *result = [[self managedObjectContext] executeFetchRequest:fetchRequest error:&error]; I'd like to fetch already sorted objects rather then fetch them all and then sort in the code. Any tips appreciated.

  • Three Java classes: point out all the issues you can find!

    - by Sicarius
    I wrote three classes for a colleague of mine (I'm new at this job). They compile just fine, but he tells me there are "defects, bugs, and style problems." He wants me to print the files out and mark the problems such as the standard coding conventions, best practices, format, design, and logic. I wrote this code when I was extremely tired and I plan to rewrite it completely. My mistake was showing to it before looking it over myself again. However, he still wants me to do the markings on paper. Any input is greatly appreciated! The three Java classes ['Station.java', 'ParserInt.java', 'ParserException.java'] are uploaded here: http://www.megaupload.com/?d=N2CUVSV2

  • C++ get method - returning by value or by reference

    - by HardCoder1986
    Hello! I've go a very simple question, but unfortunately I can't figure the answer myself. Suppose I've got some data structure that holds settings and acts like a settings map. I have a GetValue(const std::string& name) method, that returns the corresponding value. Now I'm trying to figure out - what kind of return-value approach would be better. The obvious one means making my method act like std::string GetValue(const std::string& name) and return a copy of the object and rely on RVO in performance meanings. The other one would mean making two methods std::string& GetValue(...) const std::string& GetValue(...) const which generally means duplicating code or using some evil constant casts to use one of these routines twice. #Q What would be your choice in this kind of situation and why?

  • possibility to do type/data conversion of data returned by ria services?

    - by reinier
    My service returns an byte array, which I have to convert to an 'animated gif' (using imagetools since silverlight doesn't support it yet) I was wondering, is it possible to insert some code at the client, where I can do the conversion before the actual object is returned to whatever it is binded against? On the server side, the queries can be customized before it is sent over the wire. I'm asking for the exact opposite, can I do some on the fly conversions the moment they get of the wire and before they are returned to the controls. If I'm overthinking this and there is a smarter/better/easier way to do it, I'm all for such an answer as well

  • AS3 Add Event Listener in For Each

How do I add an Event Listener to every element created in the for each loop? This is my code: for each(var showCase:ShowCaseItem in _bllShowCase.arrShowCase) { var listItem:ListItemShowCase = new ListItemShowCase(showCase); listItem.y = yPos; listItem.addEventListener("ITEMDELETED", refreshShowCaseItems); this.addChild(listItem); yPos += 20; } I hope you understand my question.

  • how to save state of dynamically created editTexts

    - by user922531
    I'm stuck at how to save the state of my EditTexts on screen orientation. Currently if text is inputted into the EditTexts and the screen is orientated, the fields are wiped (as expected). I am already calling onSaveInstanceState and saving a String, but I have no clue on how to save the EditTexts which are created in code and then retrieve them and add them to the EditTexts when redrawing the activity. Snippet of my code: My main activity is as follows: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // get the multidim array b = getIntent().getBundleExtra("obj"); m = (Methods) b.getSerializable("Methods"); // method to draw the layout InitialiseUI(); // Restore UI state from the savedInstanceState. if (savedInstanceState != null) { String strValue = savedInstanceState.getString("light"); if (strValue != null) { FLight = strValue; } } try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** Called when the back button is pressed. */ @Override public void onResume() { super.onResume(); try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** saves data before leaving the screen */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("light", FLight); } /** called when exiting / leaving the screen */ @Override protected void onPause() { super.onPause(); Log.d(TAG, "onPause()"); if (mCamera != null) { mCamera.stopPreview(); mCamera.release(); mCamera = null; } } /* * set up the UI elements - add click listeners to buttons used in * onCreate() and onConfigurationChanged() * * Set the editTexts fields to show the previous readings as Hints */ public void InitialiseUI() { Log.d(TAG, "Start of InitialiseUI, Main activity"); // get a reference to the TableLayout final TableLayout myTLreads = (TableLayout) findViewById(R.id.myTLreads); // Create arrays to hold the TVs and ETs final TextView[] myTextViews = new TextView[m.getNoRows()]; // create an empty array; final EditText[] myEditTexts = new EditText[m.getNoRows()]; // create an empty array; for(int i =0; i<=m.getNoRows()-1;i++ ){ TableRow tr=new TableRow(this); tr.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // create a new textview / editText final TextView rowTextView = new TextView(this); final EditText rowEditText = new EditText(this); // setWidth is needed otherwise my landscape layout is OFF rowEditText.setWidth(400); // this stops the keyboard taking up the whole screen in landscape layout rowEditText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI); // add some padding to the right of the TV rowTextView.setPadding(0,0,10,0); // set colors to white rowTextView.setTextColor(Color.parseColor("#FFFFFF")); rowEditText.setTextColor(Color.parseColor("#FFFFFF")); // if readings already sent today set color to yellow if(m.getTransmit(i+1)==false){ rowEditText.setEnabled(false); rowEditText.setHintTextColor(Color.parseColor("#FFFF00")); } // set the text of the TV to the meter name rowTextView.setText(m.getMeterName(i+1)); // set the hint of the ET to the last submitted reading rowEditText.setHint(m.getLastReadString(i+1)); // add the textview to the linearlayout rowEditText.setInputType(InputType.TYPE_CLASS_PHONE);//InputType.TYPE_NUMBER_FLAG_DECIMAL); tr.addView(rowTextView); tr.addView(rowEditText); myTLreads.addView(tr); // add a reference to the textView myTextViews[i] = rowTextView; myEditTexts[i] = rowEditText; } final Button submit = (Button) findViewById(R.id.submitReadings); // add a click listener to the button try { submit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.d(TAG, "Submit button clicked, Main activity"); preSubmitCheck(m.getAccNo(), m.getPostCode(), myEditTexts); // method to do HTML getting and sending } }); } catch (Exception e) { Log.d(TAG, "Exceptions (submit button)" + e.toString()); } }// end of InitialiseUI I don't need to do anything with these values until a button is clicked. Would it be easier if they were a ListView, i'm guessing I would still have the problem of saving them and retrieving them on rotation. If it helps I have an object m which is a string[][] I could temporarily somehow store them in

  • Are Ext JS files necessary in a working site?

    - by songdogtech
    I've inherited a high-traffic site that loads some Ext javascript files and I'm trying to trim some bandwidth usage. Are Ext libraries necessary for development only or are they required for the finished site (I've never used Ext.) The site loads ext-base.js, ext-all-debug.js, expander.js, exteditor.js. It appears that expander.js and exteditor.js have some site specific code, so they should stay? But what about ext-base.js and ext-all-debug.js? Am I reading this correctly - are base and debugging libraries necessary for a live site?

  • Flash CS5 AS3 drop shadow filter won't print

    - by Blake uburuDOTcom
    Hello all, I've tried searching quite a bit to discover why I don't seem to be able to print drop shadow filters from within Flash. I have trouble printing, but if the movieclip I want to print has or contains a drop shadow, that clip will print sans the drop shadow. Anyone have any insight as to why this might be happening? If you want to try it out yourself, here is the simple print code I'm using. Just put something inside contentmc with a dropshadow and print it. print_btn.addEventListener(MouseEvent.CLICK,printContent); function printContent(evt:MouseEvent) { var printJob:PrintJob = new PrintJob(); if (printJob.start()) { if (content_mc.width>printJob.pageWidth) { content_mc.width=printJob.pageWidth; content_mc.scaleY=content_mc.scaleX; } printJob.addPage(content_mc); printJob.send(); } }
