How to get AFExecuteThisScript to return the value of Net.HTTP.request (asynchronous)?

I have an Acrobat only plugin, developed in 2005 VS.  Originally with Acrobat 7 SDK, now updated to use Acrobat 9 SDK.  The ultimate goal of this feature is to open a PDF file from a web server Agile: If a user string, a URL is created, a request sent to the URL, then pay back the answer.  The answer can be either the PDF itself or a string path to the PDF file.  I thought it would be easier to use the version of PDF path to simply open the new PDF of the http:// address.

I created a folder level javascript with a call to Net.HTTP.request confidence.  I have a script that works when invoked from a menu item added by the folder level javascript file.  But when you use this same command in my C++ with AFExecuteThisScript code, I can't get the HTTP response to finish pending in the code for the result.

The Net.HTTP.request and the asynchronous callbacks confuse me, so maybe that's my big problem.  I could not Net.HTTP.request to return a value in a service simple javascript right now, I'm trying to use a "global" variable in the JavaScript folder level and two calls.  The first call "sets" the global variable, the other "becomes" it.  But this seems to be the issue.  When I have my code debugging or stop execution, the part of the response of the Net.HTTP.request is never called.  But when I left to go beyond this step with error recovery, the answer appears later.

So how kick off of the Net.HTTP.request and be notified when it's over?  either in JavaScript or VC ++?

Any help is appreciated.  Even if the best option is to stream the file from the web server to a local file and then open the (this is the option that I take in another tool that runs outside of Acrobat).

Here's the code.

Javascript controls at the level of the files (urls truncated for the post)

var THE_PATH = '';

function setTHE_PATH ( gURL ) {
    console.println('setTHE_PATH Begin');
    var params =
    {
        cVerb: 'GET',
        cURL: gURL,
        oHandler: 
            {
                response: function( msg, uri, e)
                {
                    console.println('response method: Setting Path');
                    THE_PATH = SOAP.stringFromStream( msg );
                    console.println('<<' + THE_PATH + '>>');
                }
            }
    };
    console.println('URL: ' + params.cURL + '\n  oHandler: ' + params.oHandler );
    console.println('Path: ' + THE_PATH );
    var netResult = trustedNetHTTPrequest(params);
    console.println('setTHE_PATH End');
    return THE_PATH;
};

trustedNetHTTPrequest = app.trustedFunction( 
    function ( params ) {
        console.println('trustedNetHTTPrequest begin');
        app.beginPriv();
        var netResult = Net.HTTP.request( params );
        app.endPriv();
        console.println('trustedNetHTTPrequest end');
        return netResult;
    }
);

Added MenuItems with JavaScript at the folder level

app.addMenuItem( { 
    cName: "mysetTHE_PATH", 
    cUser: "set THE_PATH", cParent: "Tools", 
    cExec: "setTHE_PATH('http://......&getURL=true');",
    nPos: 0 
} );    

app.addMenuItem( { 
    cName: "mygetTHE_PATH", 
    cUser: "get THE_PATH", cParent: "Tools", 
    cExec: "console.println( THE_PATH );",
    nPos: 0 
} );  

Here's the JavaScript Console output when you run these two commands:

setTHE_PATH Begin
URL: http://......&getURL=true
  oHandler: [object Object]
Path: 
trustedNetHTTPrequest begin
trustedNetHTTPrequest end
setTHE_PATH End
response method: Setting Path
<<https://......DesiredFilename.pdf>>

Here is the function in the plugin C++, with additional measures to prove AFExecuteThisScript works here

sprintf(jsScript, "testVal='%s';event.value = testVal;", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is the passed-in URL, as expected.
sprintf(jsScript, "setTHE_PATH('%s');event.value = 'Step 1 Worked!!';", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is 'Step 1 Worked!!', as expected.
sprintf(jsScript, "event.value = THE_PATH;", strURL.c_str() );
AFExecuteThisScript( aPdDoc, jsScript, &pReturnValue );
// After this, pReturnValue is NULL

This is the JavaScript Console output when you run the commands using the plugin (mode debugger, to wait after step 1)

setTHE_PATH Begin
URL: http://......&getURL=true
  oHandler: [object Object]
Path: 
trustedNetHTTPrequest begin
trustedNetHTTPrequest end
setTHE_PATH End

Note that he never gets to the part of the "method of response.

Thank you!

You need not limit yourself to the plugin API. The requests HTTP from C/C++ is a fairly common condition, just observe the restrictions in my answer.

  • Property of hierarchy DRM: EPMA. SharedDimension - how to get it filled with the values?

    We have a hierarchy of DRM, we want to push to a Dimension of sharing EPMA. In DRM, selecting the hierarchy and by changing the 'Dimension' shared property, the drop-down list box previously had values in there (some have been our shared Dimensions EPMA, but several us not the Shared Dimensions) but no longer has any selectable values. How do we get DRM to sort the list of the Shared Dimensions of our EPMA instance in the drop-down list of properties shared Dimension?

    Hello

    I could be wrong completely here, but that's what I discovered trying to look for EPMA. Property of SharedDimension.

    This property gives me drop-down list without having to do anything and the drop down menu is the list of groups available in hierarchy, but if I'm putting some values manually in the definition of ownership--> the list of values is not showing me all the values (list of groups of hierarchies and not the value created manually) in the drop-down list.

    I think that this property will not take a different list than list of group hierarchy as the Data Type defined for that property in the model of the APP is "Group of the hierarchy". Once again this property is used in the export "EPMA. E.M.P. architect Shared Library"to penetrate the hierarchies EPMA Shared Library.

    Then you can try to see if all values are entered in the definition of the property--> list and try to delete it OR to check if the required groups in the hierarchy are created in consequence.

    Let me know if it helps

    Thank you

  • How to return the value 0 for no data using the County?

    Hi all
    I used this query to count the number of records for each month of the year:

    INFORMATION I

    TO_DATE GROUP (TO_CHAR (INSERT_DATE, 'MM'), 'MM')

    ORDER BY TO_DATE (TO_CHAR (INSERT_DATE, 'MM'), 'MM')

    But this code returns no value for months without data
    I want to return the value '0' for any month of data. How, please?

    Record this value in UserData structure so it will be available in the model. http://andrejusb.blogspot.com/2012/05/solution-for-sharing-global-user-data.html

    Then use as default expression for your objects of entity attributes (something like: adf.userSession.userData.yourUserDataVar).

    Explain, using specific examples, how you get these results from these data.

     , extractvalue(value(sr2), '/PicklistValue/DisplayValue', 'xmlns="urn:/crmondemand/xml/picklist"') AS Return

                , '/soap:Envelope/soap:Body/ns:PicklistWS_GetPicklistValues_Output/ListOfParentPicklistValue/ParentPicklistValue'
                , 'xmlns="urn:/crmondemand/xml/picklist"

                   xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' )
       )
     ) sr1
   , table(
       xmlsequence(
         extract( value(sr1)
                , '/ParentPicklistValue/ListOfPicklistValue/PicklistValue'

    What is your version of the database BTW?
    10.2 and upward, you can use the XMLTable.

    Normally, I use the following query to get the value of spacing of pixels:
     select EXTRACTVALUE(t.dicom.metadata
                      ,'/DICOM_OBJECT/*[@name="Pixel Spacing"]'
                     ,'xmlns=http://xmlns.oracle.com/ord/dicom/metadata_1_0')  scale_factor
   from my_dicom_object t
    It works, but not when there are two elements. Then I get the error: "ORA-19025: EXTRACTVALUE returns the value of a single node.


    All I really need is to get the value of the first node with the name of "spacing of pixels. Despite the many examples available to do with traditional xml paths, I was unable to find an example that makes using XPATH search strings rather than direct tag structure.

    Can someone give an example?

    Thank you!

    This? :

  • How to get Firefox to ignore the status of liaison visits when printing?

    How to get Firefox to ignore the status of liaison visits when printing?

    When I print something, visited links are a different color than unvisited links.
    Is there a way to make the color even when printing?
    (without changing the story, or how things look on the screen)

    If there isn't a way to do that, how about this by adding as a feature?

    One way to do would be to create style rules customized for the printed output that hardcode the link colors for all of the printed output. Firefox supports two ways to proceed: a file userContent.css that you create in the folder settings, and a custom stylesheet applied using the Stylish extension.

    However, 'one size fits all' could lead to unreadable results or ugly on some pages. If an add-on that can do adaptive way would be better. I do not know if someone has created a.

    For sites that do not require a login and that are not personalized, you could launch the page in a private window (right click on the link > open in a new private window or copy the URL and then Ctrl + Shift + p, then paste it in the address bar and enter). Because private windows have their own history, the print should not reflect the history of your regular windows.

    How to get Firefox to check the compatibility of the add-on first, then ask me if I want to continue the update of Firefox? The update process currently only told me that an add-on has been disable after you apply the update to Firefox. Options > Advanced Options > switch to the update tab, "Warn me if this turns off one of my modules," doesn't seem to work.

    This is an add-on that does this.

    https://addons.Mozilla.org/en-us/Firefox/addon/is-it-compatible/

    More specifically, what modules are always appear as incompatible after a Firefox updated? Firefox 10, extensions that are made properly shouldn't be a problem, with a few exceptions.

    Extension that contains a binary code must be compiled for each new version of Firefox. These modules are usually installed by applications on security Norton, McAfee, ZoneAlarm, etc..

  • How to get a reference to the delivery of the program (not at base of LV)?

    Hello

    I need to create a LV application which will be:

    -Run external executable and not on LV. It has a window of the UI which will open

    -Open PS (no title, menus, etc.) and position it under the user interface

    -If the user moves main UI, LV app FP follows the window

    -If the user closes the main user interface, LV app closes and ends.

    App - LV does not display in the bar of tasks

    So, basically, I need to develop an application that will add-on to an existing GUI, so that together they look and behave like a single user interface.

    The main thing I am struggling with now is how to get a reference to the execution of UI that I call using the exec.vi system

    Help, please!

    What operating system? If you are on Windows, you can try to use the Windows API. Specifically, FindWindow to get a reference to both windows and SetParent to set the parent of one of the windows. This example gives you the basic idea.

  • Me am XP license key do not have an installation disc. How to get a copy of the Setup disk?

    Recently, I bought an IBM Net Vista original case, a site auction like eBay, but for my country (Serbia). It came with a sticker with a windows XP Professional license print top (with all holograms too, so I think this is authentic). All components in this case are mine (MB, CPU, GPU, RAM...), and I don't have an original Win XP Pro Installation CD. Can I use this license number? If so, how to get a copy of the installation disc?
