  • Remove this URL string when login fails and simply show div error

    - by Anagio
    My developer built our registration page to display a div when logins failed based on a string in the URL. When logins fail this is added to the URL /login?msg=invalid The PHP in my login.phtml which displays the error messages based on the msg= parameter is <?php $msg = ""; $msg = $_GET['msg']; if($msg==""){ $showMsg = ""; } elseif($msg=="invalid"){ $showMsg = ' <div class="alert alert-error"> <a class="close" data-dismiss="alert">×</a> <strong>Error!</strong> Login or password is incorrect! </div>'; } elseif($msg=="disabled"){ $showMsg = "Your account has been disabled."; } elseif($msg==2){ $showMsg = "Your account is not activated. Please check your email."; } ?> In the controller the redirect to that URL is else //email id does not exist in our database { //redirecting back with invalid email(invalid) msg=invalid. $this->_redirect($url."?msg=invalid"); } I know there are a few other validation types for disabled accounts etc. I'm in the process of redesigning the entire interface and would like to get rid of this kind of validation so that the div tags display when logins fail but not show the URL strings. If it matters the new div I want to display is <div class="alert alert-error alert-login"> Email or password incorrect </div> I'd like to replace the php my self in my login.phtml and controller but not a good programmer. What can I replace $this->_redirect($url."?msg=invalid"); with so that no strings are added to the URL and display the appropriate div tags? Thanks

  • Why the HelloWorld of opennlp library works fine on Java but doesn't work with Jruby?

    - by 0x90
    I am getting this error: SyntaxError: hello.rb:13: syntax error, unexpected tIDENTIFIER public HelloWorld( InputStream data ) throws IOException { The HelloWorld.rb is: require "java" import java.io.FileInputStream; import java.io.InputStream; import java.io.IOException; import opennlp.tools.postag.POSModel; import opennlp.tools.postag.POSTaggerME; public class HelloWorld { private POSModel model; public HelloWorld( InputStream data ) throws IOException { setModel( new POSModel( data ) ); } public void run( String sentence ) { POSTaggerME tagger = new POSTaggerME( getModel() ); String[] words = sentence.split( "\\s+" ); String[] tags = tagger.tag( words ); double[] probs = tagger.probs(); for( int i = 0; i < tags.length; i++ ) { System.out.println( words[i] + " => " + tags[i] + " @ " + probs[i] ); } } private void setModel( POSModel model ) { this.model = model; } private POSModel getModel() { return this.model; } public static void main( String args[] ) throws IOException { if( args.length < 2 ) { System.out.println( "HelloWord <file> \"sentence to tag\"" ); return; } InputStream is = new FileInputStream( args[0] ); HelloWorld hw = new HelloWorld( is ); is.close(); hw.run( args[1] ); } } when running ruby HelloWorld.rb "I am trying to make it work" when I run the HelloWorld.java "I am trying to make it work" it works perfectly, of course the .java doesn't contain the require java statement.

  • Web Hosting: Any web host that supports files more than 50,000 in number?

    - by Devner
    Hi all, For my PHP & mySQL based application, I am trying to buy website hosting from a host who does not have a limit on the number of files I carry in my hosting account. Almost all the websites have a common limit of 50,000 files (some websites call it 50,000 nodes). The rest(to the extent of my search) are not even close. I have gone through the various websites, Googled lot of information, have spoken with the customer service of the hosting companies and they said that they have a limit of 50,000 files and that's why they call it the LIMIT. Now I have my application, which is a kind of social networking website, where people can upload various files of varying file size. So say if 50,000 users were to join the website and upload 1 file each, the limit of 50,000 will be reached very easily and my 50,001 customer will start facing file upload problems (& so will my account). So I would like to know if there's any website hosting services that do NOT levy such restrictions. In summary, I need the following options: No maximum file limit (more than 50,000 files in account). No maximum file upload limit in server setting (10MB, 12MB, 15MB, 20MB, etc.). Ability to upload files of various types (zip, flv, jg, png, etc.). Ability to stream Audio and Video (live audio & video not necessary). Access to .htaccess Access to php.ini, my.cnf or my.ini (this would be a plus) Supports SSL. Provides dedicated hosting(& IP) as well. Monthly payments without contracts are a plus. If you know of any such website hosting services, please post a reply ( a link to the same will be appreciated ). Thank you.

  • Forces to prompt download box IE

    - by Bruno Costa
    Hello, I'm having a problem with some reports in the application I'm doing manutention I've a button that does a postback to the server and do some information and then get back to the cliente and open a popup to download the report. private void grid_ItemCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { ... ClientScript.RegisterClientScriptBlock(this.GetType(), "xxx", "<script>javascript:window.location('xx.aspx?m=x','xxx','width=750,height=350,directories=no,location=no,menubar=no,scrollbars,status=no,toolbar=no,resizable=yes,left=50,top=50');</script>"); } Then in xxx.aspx I've the code: Response.ClearContent(); Response.ClearHeaders(); Response.TransmitFile(tempFileName); Response.Flush(); Response.Close(); File.Delete(tempFileName); Response.End(); This works fine if IE option Automatic prompting for file downloads is enabled. But by default this is disabled and I need to force the download box to be prompting. Can I do anything without change a lot of code? Thanks.

  • Cursor returns zero rows from query to table

    - by brockoli
    I've created an SQLiteDatabase in my app and populated it with some data. I can connect to my AVD with a terminal and when I issue select * from articles; I get a list of all the rows in my table and everything looks fine. However, in my code when I query my table, I get a cursor back that has my tables columns, but zero rows of data. Here is my code.. mDbHelper.open(); Cursor articles = mDbHelper.fetchAllArticles(); startManagingCursor(articles); Cursor feeds = mDbHelper.fetchAllFeeds(); startManagingCursor(feeds); mDbHelper.close(); int titleColumn = articles.getColumnIndex("title"); int feedIdColumn = articles.getColumnIndex("feed_id"); int feedTitleColumn = feeds.getColumnIndex("title"); /* Check if our result was valid. */ if (articles != null) { int count = articles.getCount(); /* Check if at least one Result was returned. */ if (articles.moveToFirst()) { In the above code, my Cursor articles returns with my 4 columns, but when I call getCount() it returns zero, even though I can see hundreds of rows of data in that table from command line. Any idea what I might be doing wrong here? Also.. here is my code for fetchAllArticles.. public Cursor fetchAllArticles() { return mDb.query(ARTICLES_TABLE, new String[] {ARTICLE_KEY_ROWID, ARTICLE_KEY_FEED_ID, ARTICLE_KEY_TITLE, ARTICLE_KEY_URL}, null, null, null, null, null); } Rob W.

  • iPhone OpenGL ES Texture2D Masking

    - by Robert Neagu
    What's the best choice when trying to mask a texture like ColorSplash or other apps like iSteam, etc? I started learning OPENGL ES like... 4 days ago (I'm a total rookie) and tried the following approach: 1) I created a colored texture2D, a grayscale version of the first texture and a third texture2D called mask 2) I also created a texture2D for the brush... which is grayscale and it's opaque (brush = black = 0,0,0,1 and surroundings = white = 1,1,1,1). My intention was to create an antialiased brush with smooth edges but i'm fine with a normal one right now 3) I searched for masking techniques on the internet and found this tutorial ZeusCMD - Design and Development Tutorials : OpenGL ES Programming Tutorials - Masking about masking. The tutorial tells me to use blending to achieve masking... first draw colored, then mask with glBlendFunc(GL_DST_COLOR, GL_ZERO) and then grayscale with glBlendFunc(GL_ONE, GL_ONE) ... and this gives me something close to what i want... but not exactly what i want. The result is masked but it's somehow overbright-ed 4) For drawing to the mask texture i used an extra frame buffer object (FBO) I'm not really happy with the resulting image (overbright-ed picture) nor with the speed achieved with this method. I think the normal way was to draw directly to the grayscale (overlay) texture2D affecting only it's alpha channel in the places where the brush hits. Is there a fast way to achieve this? I have searched a lot and never got an answer that's clear and understandable. Then, in the main draw loop I could only draw the colored texture and then blend the grayscale ontop with glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA). I just want to learn to use OPENGL ES and it's driving me nuts because i can't get it to work properly. An advice, a link to a tutorial would be much appreciated.

  • Python: Most efficient way to concatenate and rearrange files

    - by user300890
    Hi, I am reading from several files, each file is divided into 2 pieces, first a header section of a few thousand lines followed by a body of a few thousand. My problem is I need to concatenate these files into one file where all the headers are on the top followed by the body. Currently I am using two loops; one to pull out all the headers and write them, and the second to write the body of each file (I also include a tmp_count variable to limit the number of lines to be loading into memory before dumping to file). This is pretty slow - about 6min for 13gb file. Can anyone tell me how to optimize this or if there is a faster way to do this in python ? Thanks! Here is my code: def cat_files_sam(final_file_name,work_directory_master,file_count): final_file = open(final_file_name,"w") if len(file_count) > 1: file_count=sort_output_files(file_count) # only for @ headers for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 else: final_file.writelines(tmp_list) break for bowtie_file in file_count: #print bowtie_file tmp_list = [] tmp_count = 0 for line in open(os.path.join(work_directory_master,bowtie_file)): if line.startswith("@"): continue if tmp_count == 1000000: final_file.writelines(tmp_list) tmp_list = [] tmp_count = 0 tmp_list.append(line) tmp_count += 1 final_file.writelines(tmp_list) final_file.close()

  • Diffrernce between BackgroundWorker.ReportProgress() and Control.Invoke()

    - by ohadsc
    What is the difference between options 1 and 2 in the following? private void BGW_DoWork(object sender, DoWorkEventArgs e) { for (int i=1; i<=100; i++) { string txt = i.ToString(); if (Test_Check.Checked) //OPTION 1 Test_BackgroundWorker.ReportProgress(i, txt); else //OPTION 2 this.Invoke((Action<int, string>)UpdateGUI, new object[] {i, txt}); } } private void BGW_ProgressChanged(object sender, ProgressChangedEventArgs e) { UpdateGUI(e.ProgressPercentage, (string)e.UserState); } private void UpdateGUI(int percent, string txt) { Test_ProgressBar.Value = percent; Test_RichTextBox.AppendText(txt + Environment.NewLine); } Looking at reflector, the Control.Invoke() appears to use: this.FindMarshalingControl().MarshaledInvoke(this, method, args, 1); whereas BackgroundWorker.Invoke() appears to use: this.asyncOperation.Post(this.progressReporter, args); (I'm just guessing these are the relevant function calls.) If I understand correctly, BGW Posts to the WinForms window its progress report request, whereas Control.Invoke uses a CLR mechanism to invoke on the right thread. Am I close? And if so, what are the repercussions of using either ? Thanks

  • comma separated values in oracle function body

    I've got following oracle function but it does not work and errors out. I used Ask Tom's way to convert comma separated values to be used in select * from table1 where col1 in <> declared in package header: TYPE myTableType IS table of varchar2 (255); Part of package body: l_string long default iv_value_with_comma_separated|| ','; l_data myTableType := myTableType(); n NUMBER; begin begin LOOP EXIT when l_string is null; n := instr( l_string, ',' ); l_data.extend; l_data(l_data.count) := ltrim( rtrim( substr( l_string, 1, n-1 ) ) ); l_string := substr( l_string, n+1 ); END LOOP; end; OPEN my_cursor FOR select * from table_a where column_a in (select * from table (l_data)); CLOSE my_cursor END; above fails but it works fine when I remove select * from table (l_data) Can someone please tell me what I might be doing wrong here??

  • Confused about UIView frame property

    - by slowfungus
    I'm building a prototype iPad app that draws diagrams. I have the following view hierarchy: UIView UIScrollView DiagramView : UIView TabBar NavigationBar And a UIViewController subclass holding all that together. Before drawing the diagram the first time I calculate the dimensions of the diagram, and set the DiagramView frame to that size, and the content size of the scrollview as well. -(void)recalculateBounds { [renderer diagram:diagram shouldDraw:NO]; SQXRect diagramRect = SQXMakeRect(0.0,0.0,[diagram bounds].size.width,[diagram bounds].size.height); self.frame = diagramRect; [(UIScrollView*)[self superview] setContentSize:diagramRect.size]; } I should disclose that the frame is being set to about 1500 x 3500 which i know is ridiculous. I just want to focus on some other parts of the app before I get into optimizing the render code. This works beautifully, except that the rect being passed to drawRect is not the size that I set, and my drawing is getting clipped at the bottom. Its close the size i set, but bigger in width, and shorter in height. Also of note, is the fact that if I force the frame to be much bigger than what I know the diagram needs, then the drawRect:rect is big enough, and no clipping occurs. Of course this has me wondering if the frame size needs to take into account some other screen real estate like the toolbars but my reading of the docs tells me the frame is in superview coordinates, which would be the scrollview so I reckon I need to worry about such things. Any idea what is causing this discrepancy?

  • C# web service, MySql encoding problem

    I use C# web service to insert, delete and get data from MySql database. The problem is some of the data is in Macedonian (Cyrilic). When I insert directly in the database, it inserts ok. For example: "???" is "???". When I insert throgh the service, it's not. For example: "???" is "???". When I try to get data throug the service, it gets it ok. What's the problem with the inserting? Here is part of my code for inserting: MySqlConnection connection = new MySqlConnection(MyConString); MySqlCommand command = connection.CreateCommand(); command.CommandText = "INSERT INTO user (id_user, name VALUES (NULL, ?name);"; command.Parameters.Add("?name", MySqlDbType.VarChar).Value = name; connection.Open(); command.ExecuteReader(); connection.Close(); return thisrow; Tnq U in advance!!!

  • Cocoa document-based app: Notification not always received by observer

    - by roysolay
    Hi, I hope somebody can help with my notification problem. I have a notification which looks to be set up correctly but it isn’t delivered as expected. I am developing a document based app. The delegate/ document class posts the notification when it reads from a saved file: [[NSNotificationCenter defaultCenter] postNotificationName:notifyBsplinePolyOpened object:self]; Logging tells me that this line is reached whenever I open a saved document. In the DrawView class, I have observers for the windowOpen notification and the bsplinePoly file open notification: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(mainWindowOpen:) name:NSWindowDidBecomeMainNotification object:nil]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(savedBspline:) name:notifyBsplinePolyOpened object:nil]; - (void) mainWindowOpen:(NSNotification*) note { NSLog(@"Window opened"); _mainWindow = [note object]; } - (void) savedBspline:(NSNotification*) note { NSLog(@"savedBspline called"); NSLog(@"note is %@", [note name]); } The behavior is odd. When I save and close the main window and reopen it, I get the “Window opened” message but not the “savedBspline called” message. If I leave a main window open and open a previously saved session, I get the “Window opened” message and the “savedBspline called” message. I have searched online discussion and Apple DevCenter documentation but I have not seen this problem.

  • Parsing custom time format with SimpleDateFormat

    - by ggrigery
    I'm having trouble parsing a date format that I'm getting back from an API and that I have never seen (I believe is a custom format). An example of a date: /Date(1353447000000+0000)/ When I first encountered this format it didn't take me long to see that it was the time in milliseconds with a time zone offset. I'm having trouble extracting this date using SimpleDateFormat though. Here was my first attempt: String weirdDate = "/Date(1353447000000+0000)/"; SimpleDateFormat sdf = new SimpleDateFormat("'/Date('SSSSSSSSSSSSSZ')/'"); Date d1 = sdf.parse(weirdDate); System.out.println(d1.toString()); System.out.println(d1.getTime()); System.out.println(); Date d2 = new Date(Long.parseLong("1353447000000")); System.out.println(d2.toString()); System.out.println(d2.getTime()); And output: Tue Jan 06 22:51:41 EST 1970 532301760 Tue Nov 20 16:30:00 EST 2012 1353447000000 The date (and number of milliseconds parsed) is not even close and I haven't been able to figure out why. After some troubleshooting, I discovered that the way I'm trying to use SDF is clearly flawed. Example: String weirdDate = "1353447000000"; SimpleDateFormat sdf = new SimpleDateFormat("S"); Date d1 = sdf.parse(weirdDate); System.out.println(d1.toString()); System.out.println(d1.getTime()); And output: Wed Jan 07 03:51:41 EST 1970 550301760 I can't say I've ever tried to use SDF in this way to just parse a time in milliseconds because I would normally use Long.parseLong() and just pass it straight into new Date(long) (and in fact the solution I have in place right now is just a regular expression and parsing a long). I'm looking for a cleaner solution that I can easily extract this time in milliseconds with the timezone and quickly parse out into a date without the messy manual handling. Anyone have any ideas or that can spot the errors in my logic above? Help is much appreciated.

  • Help with PHP simplehtmldom - Modifiying a form.

    - by onemyndseye
    Ive gotten some great help here and I am so close to solving my problem that I can taste it. But I seem to be stuck. I need to scrape a simple form from a local webserver and only return the lines that match a users local email (i.e. onemyndseye@localhost). simplehtmldom makes easy work of extracting the correct form element: foreach($html->find('form[action*="delete"]') as $form) echo $form; Returns: <form action="/delete" method="post"> <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php"> http://www.linux.com/rss/feeds.php </a> [email: onemyndseye@localhost (Default) ]<br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml"> http://www.ubuntu.com/rss.xml </a> [email: onemyndseye@localhost (Default) ]<br /> However I am having trouble making the next step. Which is returning lines that contain 'onemyndseye@localhost' and removing it so that only the following is returned: <input type="checkbox" id="D1" name="D1" /><a href="http://www.linux.com/rss/feeds.php">http://www.linux.com/rss/feeds.php</a> <br /> <input type="checkbox" id="D2" name="D2" /><a href="http://www.ubuntu.com/rss.xml">http://www.ubuntu.com/rss.xml</a> <br /> Thanks to the wonderful users of this site Ive gotten this far and can even return just the links but I am having trouble getting the rest... Its important that the complete <input> tags are returned EXACTLY as shown above as the id and name values will need to be passed back to the original form in post data later on. Thanks in advance!

  • Can I dispose a DataTable and still use its data later?

    Noob ADO.NET question: Can I do the following? Retrieve a DataTable somehow. Dispose it. Still use its data. (But not send it back to the database, or request the database to update it.) I have the following function, which is indirectly called by every WebMethod in a Web Service of mine: public static DataTable GetDataTable(string cmdText, SqlParameter[] parameters) { // Read the connection string from the web.config file.

  • opengl shader make color "disappear"

    - by JFoulkes
    hi, I'm new to opengl and shaders. I'm trying to do some augmented reality on the iphone and messing about with shaders to alter a feed from the camera. What I'm trying to achieve is the appearance that an object in a picture has disappeared by setting the color to match the surrounding colour. I have a yellow rectangle and in it is a small red circle. I want to give the impressed the red circle has disappeared by setting the colour to be yellow. It won't always be solid colours but I'm just trying to get the basics down first. Currently I have a simple shader which will make a red colour lighter but this isn't ideal because it doesn't get close to the surrounding colour and I want this to work for different coloured objects and different coloured surrounding. I'm not even 100% shaders are what I need to be looking at or even opengl. I'm using it because of the performance it gives on the iPhone. I'm basically asking if: Anyone has done or seen anything similar Am I barking up the wrong tree using opengl es and opengl sl? Is this even possible? Cheers.

    in my app' i'm recieving data from serial port and save them into two bool arrays. And depends on these array i'm setting checkboxes. But checkboxes are not updating only when i change the tabs.... Here's how i'm doin' it(maybe there's better way how to do it) private void comboBoxCommunication_SelectionChanged(object sender, SelectionChangedEventArgs e) { if (serialPort.IsOpen) { recieveThread.Abort(); serialPort.Close(); } ComboBoxItem cbi = (ComboBoxItem)comboBoxCommunication.SelectedItem; portCommunication = cbi.Content.ToString(); serialPort.PortName = portCommunication; try { serialPort.Open(); recieveThread = new Thread(dataRecieving); prijmiThread.Start(); checkBoxI1.IsChecked = vstupy[0] ? true : false; checkBoxI2.IsChecked = inputs[1] ? true : false; checkBoxI3.IsChecked = inputs[2] ? true : false; checkBoxQ2.IsChecked = outputs[3] ? true : false; } catch (IOException ex) { MessageBox.Show(ex.ToString(), "Error!", MessageBoxButton.OK, MessageBoxImage.Error, MessageBoxResult.OK); } } private void dataRecieving() { if (serialPort.IsOpen) { int i = serialPort.ReadChar(); if (i == 'A') { inputs[0] = true; } else if (i == 'a') { inputs[0] = false; } if (i == 'B') { inputs[1] = true; } else if (i == 'b') { inputs[1] = false; } if (i == 'C') { inputs[2] = true; } else if (i == 'c') { inputs[2] = false; } if (i == 'D') { outputs[0] = true; } else if (i == 'd') { outputs[0] = false; } } }

  • Problem with object serialization in Applet-Servlet communication

    - by Bruce
    Hi guys, I spent a lot of time on thinking what is wrong with the following code. I send the object from my applet to servlet and then I read the object from servlet. Everything goes fine till reading serialized object from the servlet - I got IOException. Thank you in advance! Here is the code: Applet: try { URL servletURL = new URL(this.getCodeBase().getProtocol(), this.getCodeBase().getHost(), this.getCodeBase().getPort(), "/MyApplet"); URLConnection servletConnection = servletURL.openConnection(); servletConnection.setDoInput( true ); servletConnection.setDoOutput( true ); servletConnection.setUseCaches( false ); servletConnection.setRequestProperty( "Content-Type", "application/x-java-serialized-object" ); ObjectOutputStream output; output = new ObjectOutputStream( servletConnection.getOutputStream( ) ); output.writeObject( someObject ); output.flush( ); output.close( ); ObjectInputStream input = new ObjectInputStream( servletConnection.getInputStream( ) ); // Here I got the exception myObject = ( SomeObject ) input.readObject( ); } catch (java.io.IOException ioe) { System.err.println(ioe.getStackTrace()); } catch (Exception e) { System.err.println(e.getStackTrace()); } Servlet: response.setContentType("application/x-java-serialized-object"); try { ObjectInputStream inputFromApplet = new ObjectInputStream(request.getInputStream()); SomeObject myObject = (SomeObject) inputFromApplet.readObject(); ObjectOutputStream outputToApplet = new ObjectOutputStream(response.getOutputStream()); outputToApplet.writeObject(myObject); outputToApplet.flush(); } catch(Exception e) { // ... }

  • What should be taught in a "Fundamentals of programming" course at university?

    - by Dervin Thunk
    I have started a new question (see here), because I think the topic is of importance in a more general form. The question is now: If you were a professor at a Computer Science Dept. in some university, what would make it into your course? This is a programming course, second term, first year computer science/computer engineering. Remember you have a limited amount of time, and students are of different levels of competence, and some may be scientists, but some will also go on to be programmers in companies of different kinds. You have to cater to all. Bonus: What language? (Although see this question for my current thoughts about this...) Maybe you want to attach a course outline from some university? See here for an even more general question about this. Answer: I can't really summarize this post... I guess it was too subjective. However, it looks like we have to cover the history of computing up to a certain extent, computer architecture (memory, registers, whatever), C, and finally some basic algos and data structures in a problem solving fashion. This will be the bare bones of the course. Thanks all. I will accept the most voted up answer to close the thread, as it should be done.

  • How do I resize an iframe with dynamic content?

    - by Middletone
    I'm populating an iframe with some contents that are injected into it but I'm unable to size it correctly. I've tried a variety of methods but here is the most recent code. After populating the iframe with an html based mail message it doesn't seem to register the scroll height. <iframe scrolling="no" width="100%" onload="javascript:(LoadIFrame(this));" > HTML content goes here. Make sure it's long enough to need to scroll before testing. </iframe> <script type="text/javascript"> function LoadIFrame(iframe) { $("iframe").each(function() { $(this).load(function() { var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } this.height = (doc.body.scrollHeight + 50) + 'px'; this.onload = ''; }); txt = $(this).text(); var doc = this.document; if (this.contentDocument) { doc = this.contentDocument; } else if (this.contentWindow) { doc = this.contentWindow.document; } else if (this.document) { doc = this.document; } doc.open(); doc.writeln(txt); doc.close(); }); } </script>

  • How to use IO.popen to write-to and read-from a child process?

    - by mackenir
    I am running net share from a ruby script to delete a windows network share. If files on the share are in use, net share will ask the user if they want to go ahead with the deletion, so my script needs to inspect the output from the command, and write out Y if it detects that net share is asking it for input. In order to be able to write out to the process I open it with access flags "r+". When attempting to write to the process with IO#puts, I get an error: Errno::EPIPE: Broken pipe What am I doing wrong here? (The error occurs on the line net_share.puts "Y") (The question text written out by net share is not followed by a newline, so I am using IO#readpartial to read in the output.) def delete_network_share share_path command = "net share #{share_path} /DELETE" net_share = IO.popen(command, "r+") text = "" while true begin line = net_share.readpartial 1000 #read all the input that's available rescue EOFError break end text += line if text.scan("Do you want to continue this operation? (Y/N)").size > 0 net_share.puts "Y" net_share.flush #probably not needed? end end net_share.close end

  • Python 3, urllib ... Reset Connection Possible?

    - by Rhys
    In the larger scale of my program the goal of the below code is to filter out all dynamic html in a web-page source code code snippet: try: deepreq3 = urllib.request.Request(deepurl3) deepreq3.add_header("User-Agent","etc......") deepdata3 = urllib.request.urlopen(deepurl3).read().decode("utf8", 'ignore') The following code is looped 3 times in order to identify whether the target web-page is Dynamic (source code is changed at intervals) or not. If the page IS dynamic, the above code loops another 15 times and attempts to filter out the dynamic content. QUESTION: While this filtering method works 80% of the time, some pages will reload ALL 15 times and STILL contain dynamic code. HOWEVER. If I manually close down the Python Shell and re-execute my program, the dynamic html that my 'refresh-page method' could not shake off is no longer there ... it's been replaced with new dynamic html that my 'refresh-page method' cannot shake off. So I need to know, what is going on here? How is re-running my program causing the dynamic content of a page to change. AND, is there any way, any 'reset connection' command I can use to recreate this ... without manually restarting my app. Thanks for your response.
