• sign the document with 'Draw my signature' and send it via http-post

  Hello

  I have a pdf document with a signature field. When im opening with AcrobatReader XI, I can sign / Place Signature / draw my signature. I can't 'save a copy '. It works pretty well.

  Now, I place a button in the pdf document to be sent via http post to a given address. When I now open this PDF in the XI AcrobatReader, trying to sign. I can only do this with sign / Place Signature / use a certificate. But there is no way to "draw my signature."

  Did I miss an option to do this? Pls tell me if he has a chance to sign the document with 'Draw my signature' and send it via http-post.

  Or is this part of the concept? When I'm looking for a solution, I found EchoSign electronic signature.

  What is available depends on how the as is put in place. If you include a button with an action of type 'Submit form' and/or reader - enable the form, then e-signature (signature of drawing) will not be available in the player. If the document is compatible player then digitally signing will. So for what you want, do not Reader-enable the document and you can use the submitForm JavaScript method to submit. The site that has the JavaScript documentation was not available at the time I wrote this, but post again if you need help with that.

• Time increasing while sending data via http repeatedly on the storm

  Hi all!

  My application sends data (in general, this is a picture of ~ 1200 Kb) to the server via http.

  The data are sent ok, but the when I send data several times (without leaving the application) the time devoted to writing the data in the outputStream develops. On first use, it takes usually ~ 50 seconds, the second seconds of ~ 70, the third seconds from ~ 100... I see this problem only on the storm, others (Curve 8900, Bold, Tour) are OK. The url is used on Storm is: http://xxxxxxxxxxxxx.com/mobile/mobile.asmx;deviceside=true

  Here is the code snippet:

  private static WSResponse send(byte[] xmlBytes, WSResponseParser parser) throws Exception {
  
          HttpConnection connection = null;
      OutputStream outputStream = null;
  
         try {
              connection = (HttpConnection)Connector.open(WifiChecker.getURL(URL), Connector.READ_WRITE, true);
  
              connection.setRequestMethod(HttpConnection.POST);
              connection.setRequestProperty("Content-Type", CONTENT_TYPE);
              connection.setRequestProperty("Content-Length", String.valueOf(xmlBytes.length));
  
              outputStream = connection.openOutputStream();
  
              int offset = 0;
              int chunk = DATA_CHUNK_SIZE; // 1024
              int len = xmlBytes.length;
              while (offset < len) {
                  if (offset + chunk >= len) { // avoiding OutOfBounds Exception
                      chunk = len - offset;
                  }
                  outputStream.write(xmlBytes, offset, chunk);
                  offset += chunk;
              }
  
              xmlBytes = null;
  
              String response = getResponseAsSting(connection);
  
              WSResponse wsResponse = null;
              try {
                  wsResponse = parser.getWSResponse(response);
              } catch (Exception e) {
                  throw ApplicationException.invalidWsResponse();
           }
  
              if (!wsResponse.isSuccess()) {
                  throw new WSFailureException(wsResponse);
              }
  
              return wsResponse;
  
          } finally {
              IOUtils.safelyCloseStream(outputStream);
              IOUtils.safelyCloseStream(connection);
              if (xmlBytes != null) {
                  xmlBytes = null; // notify VM it can safely free the RAM
              }
          }
  

  I thought it may be a memory problem, so I manually cancel xmlBytes, but which does not solve the problem.

  Any ideas?

  Thanks in advance,

  Arhimed

  P. S.

  There is no question about Simulator, only on a real device of the storm.

  MSohm, thanks for your response.

  Fortunately, I have just fixed the problem. The problem was not in the code above, but in the code that made the xmlBytes. I converted bytes of the image base64 and looks like I did it dangerously on the use of the memory.

  Thanks again for your attention to this thread!

  any ideas what should I do?

  Thank you

  I mean not to define QNetworkAccessManager inside the function.

  For example:

  Declare the pointer to QNetworkAccessManager in your header file (all)

  QNetworkAccessManager *connection;
  

  and then set it in the constructor of the app inside the function you or you. In the second case, you must remove QNetworkAccessManager pointer after postFinished. (connection-> deleteLater())

  connection = new QNetworkAccessManager(this);
  

  and the full code of the POST function

  ...post(const QString &fullName, const QString &email, const QString &password)
  {
      QUrl url("http://www.rws.rajaspot.com/rs_usermanagementclient.php");
  
      QUrl postParams;
      postParams.addQueryItem("method", "rsnewuser");
      postParams.addQueryItem("fullName", fullName);
      postParams.addQueryItem("email", email);
      postParams.addQueryItem("password", password);
  
      QNetworkRequest req(url);
      req.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
  
      QNetworkReply* reply = connection->post(req, postParams.encodedQuery());
      bool ok = connect(reply, SIGNAL(finished()), this, SLOT(postFinished()));

• Send a PDF form via HTTP Post: Newbie Questions

  Hello

  I am completely new to PDF forms, so I was finding the documentation and the overwhelming options.

  I'm hoping to get directed to the documentation/tutorials/examples that I really need.

  I want to build a 'proof of concept' for my boss.  I would like to include a screen in our webapp Java (JSP & spring) where either a PDF form is incorporated or is accessible via a link.

  I have

  • Standard Adobe Acrobat Distiller X license
  • Adobe Acrobat X Standard
  • Microsoft Office 2010

  I made a little, the form of Microsoft Word 3 field.  I then he converted via distill into a PDF form.

  I then found this document on how to submit a PDF form to a component side Server:

  http://acrobatusers.com/tutorials/form-submit-e-mail-Demystified

  My big problem with this document, is not an example, nor an example of what is happening in an HTML page complete.   Because I I have a few questions:

  1. I see such an example somewhere?
  2. The result of the call to the javascript function doc. SubmitForm (urlToMyServerSideComponent) go in a script tag on the HTML page as other javascripts?
  3. Can I submit the function from an HTML button run or I put a button 'send' the PDF form?
  4. Do I need Adobe LiveCycle to create a PDF form with a button "submit"?  Free versions?
  5. Can I send via HTTP POST?
  6. Do I need Adobe LiveCycle to create a PDF form with a digital signature?
  7. Is there a document/tutorial that fits where I want to? (Please no books, I am tyring to show to my boss that this is something which can be done in a reasonable amount of time, no time to get and go through a book).

  Thanks in advance for things which make me pointed in the right direction

  Steve

  This seems to imply that I can do a such acroform without using an application or can I use an application with an option to write code by hand.  Am I wrong?  If yes could tell me on the document from the beginner to learn how to do this?    I have acrobat, but I don't have the 'send to server' option in the menu to distribute.

  No, you would use Acrobat to add the button and configure. As said earier, you want not to use distribute the form for this type of shape. Simply add a button on one of the pages of the PDF and give a mouse action upward to "submit a form":

  

  The video tutorial contains more information on the treatment of the submission on the server. Again, do not use the option to distribute the form in Acrobat.

• Getting 7 error with the HTTP POST vi method when deplyed ISO crio as executable... urgent!

  Hi all

  I have an application where I can access the net server point of LabVIEW via the HTTP protocol to send the data. My application works fine when I run it on XP, and also sometimes on cRIO. I'm writing and reading files to store and read data from the server.

  When I do my application executable and deployed on cRIO I am constantly 7 error that says "Error in the node library function to call at the POST vi LabVIEWHTTPCLIENT".

  After getting this error if I try to run the my new project the crio (not through exe) I keep getting the same error. This means once the executable file is deployed on the crio, I get the error in my project application which was working fine before you deploy the executable file.

  7 occurs very frequently. and I am unable to find the reason. I gave all the paths in the constant form located on crio and files accessible also when the application is run.

  Is someone can you please help me what this error 7?

  as a result, that it is bound to the HTTP POST vi method...

  How can it be fix?

  Its quite urgent...

  Thanks in advance.

  Solution is provided by the NOR... Vi POST method missing two files that need to be there in the startup of the CRIO.insted folder there is in the system folder. That's why when running the exe that the startup on crio application it gives error as the files are not there. The fix for this HTTP POST vi update isn't out yet EITHER.

• HTTPS post problem

  Hey guys I have problems to send data to a back-end server. I am trying to send the data using the http post method. Now, the connection works fine, her gives me a 200 OK response, after which I try to write data. But unfortunately the server receives all the data. My code is as follows:

  String toSend = "write it to the server";

  Byte [] postData = toSend.getBytes ();

  c = (HttpsConnection) Connector.open ("https://myurl;deviceside=true");

  c.setRequestProperty ("Content-Type", "application/x-www-formulaires-urlencoded");
  c.setRequestProperty ("Content-Language", "en-US");
  c.setRequestProperty ("Content-Length", String.valueOf (postData.length));
  c.setRequestMethod (HttpConnection.POST);
  int responseCode = c.getResponseCode ();

  dStr = new DataOutputStream (c.openOutputStream ());
  dStr.write (postData);

  dStr.flush ();
  dStr.close ();

  c.Close ();

  Am I missing something here? Help would be greatly appreciated.

  Thank you

  David

  Get rid of the flush.

  do the "getResponse" before closing the stream. This void anyway.

  Like this:

  Set the properties of the application
  setRequestProperties (m_httpConnection);
                         
  dataOutputStream = m_httpConnection.openDataOutputStream ();
  writeRequestPayload (dataOutputStream);
     
  get and store the response for this request code
  m_responseCode = m_httpConnection.getResponseCode ();

  Now you can close the stream

• Help with JSON HTTP Post request

  Still fairly new to QT so I try to send a query with some json http post, I'm pulling the json to a file and which seems to work fine but I get a http 500 error. I want to just make sure that my code is correct before contacting the company that webservice I use here is my code:

   JsonDataAccess jda;
      QVariant list = jda.load(QDir::currentPath() +"/app/native/assets/jsonData/myjson.json");
  
      qDebug()<post(request, list.toByteArray());
  

  I have a feeling that I'm passing in json data in the wrong post method. Any help is appreicated

  Hello

  You send an empty server string because list.toByteArray () returns an empty string.

  You must save the QByteArray list;

  QByteArray result;
  jda.saveToBuffer(list, &result);
  
  // and then
  
  QNetworkReply *reply = networkAccessManager->post(request, result);
  

  or

  Simply load the json with QFile file

  QFile file(YOUR_JSON);
  if (!file.open(QIODevice::ReadOnly)){
      qDebug() << Q_FUNC_INFO << file.errorString();
      return;
  }
  QByteArray result = file.readAll();
  file.close()
  
  QNetworkReply *reply = networkAccessManager->post(request, result);

• Simple HTTP post

  Does anyone know of a document/tutorial that shows you how to make a post of simple http form from a flex application?
  I guess it's possible to do a http post to a ColdFusion page that uses only the usual FORM variables to receive the data.
  
  After seeing this it would make life a lot easier to create "rich forms" in flex instead of DHTML, javascript & CSS.
  
  I see many examples of data by pulling in a flex front end, but not much focus on sending data.
  
  See you soon

  I took this example and he wrote style CF.

  Works like a charm...

• Problem when using SOAP requests with HTTP POST function

  Hello!

  Using the vi of HTTP POST to send SOAP requests to a device, I encountered a problem.

  Take care of the HTTP header for you HTTP POST vi and defines the type of 'content' as "Content-Type: application/x-www-formulaires-urlencoded. Who is considered to be 'non-soap' requests by some Web servers.

  Standards W3C says in this case, you should be content-type: "application/soap + xml".

  Link to the page to W3C standard: http://www.w3.org/TR/soap12-part0/#L26866

  That is possible to update this feature in a future release so that programmers can choose (or type) the necessary content type?

  Have you tried "Add header" to change?

• How to disseminate data over HTTP

  Hi all

  Need a little bit of sense on this one because I think (and hope) it's pretty simple, but I can't for the life of understand me. Not much on the TCP/IP or HTTP protocol before am so a little out of my comfort zone.

  I'm talking to a momo SoMat Lite. There is a command that I can call in a web browser that works perfectly (from the point of view of obtaining data and to the screen): http://192.168.100.100:2345 / realtime? rate = 10 & Headers = 0

  It returns data, continuous, at my window Chrome. If I scroll down, I find that new values are written on the bottom of the page at all times. Everything is in a text format.

  Now, all I want to do is to replicate that in LabVIEW. This is where I am stuck. I tried various HTTP and TCP/IP Protocol and got more or less errors. I have attached a VI that does not work. The reasons why? I don't get errors until I get an error timeout on TCP/IP (error 56) of reading. If I run it again I get error 60 since the first VI.

  Any help gratefully received.

  Looking at the details of the HTTP protocol for the device, you have 2 options:

  (1) use the screws of HTTP Client to claim a fixed amount of data
  (2) use the screws of TCP/IP to implement a HTTP protocol that can "keepalive" the TCP connection to read data continuously

  With Option 1, the VIs HTTP will send an HTTP request and wait for a response to be sent followed by the closing of the connection device. I think that the URL you provide maintains the TCP connection alive to continue to send data (which are added continuously to the page) which probably means that the client HTTP VI will continue to read the data until the VI is to expire. You would need to ask a set amount of data every time that you run the VI of HTTP (for example 1 data point) which must be returned within the time limit of the VI of HTTP.

  I think with Option 2, you need to implement a basic HTTP request in TCP - similar to what you did but rather to send a string that is a URL, you must send a properly formatted HTTP GET request header and then to the TCP read HTTP response headers followed by your data, you will receive.

  According to Wikipedia... .the string must be formatted as follows:

  -A request line (for example GET /realtime? Rate = 10 & Headers = 0 HTTP/1.1)

  -The request headers (maybe not required... but a "Host: " line apparently is required as part of the HTTP/1.1 specification ")

  -A blank line

  -Body of the message (probably not necessary...)

  If you use the CRLF of the PCT read mode, you should get a reading by line of HTTP headers (which cannot be sent by the device - I guess that's what the headers = 0 is for) followed by a reading by row of data (as you saw by accessing it via the browser).

  If you use some of the tools in your browser (for example in chrome - tools-> tools development-> Network tab) - you can usually see the raw HTTP sent/received data when you access the URL you provided.
