Printing Problem with AlivePDF

BradOleson — Wed, 09 Jun 2010 19:43:49 GMT

The continuing printing saga:

I've installed a sample print utility from this thread:
http://forums.esri.com/Thread.asp?c=158&f=2421&t=299883&mc=11#936860

The solution calls for 2 parts - installing a .Net piece on the server in IIS and then adding the Flex components to the Flex project. Everything seems fine on the Flex side, but when I run the create PDF code from the Flex app there is an error in the .Net piece.

When run on a remote machine the attached Error1 page appears. When I check the app URL on the server side, I get a little more detail, but still errors out, as shown in the Error2 attachment.

I sent the author an e-mail directly, but thought I'd post here as well to see if anyone knew right off if there was a fix. I've already checked .Net versions and 3.5 is the installed / required version. I've also created a separate app pool in IIS in case that was an issue (from reading online ASP .Net forums / blogs).

Anyone have any ideas?

Brad

Brad,

That dot Net portion can be avoid completely if you force your clients to use Flash Player 10. If you set your flex projects html wrapper to use flash player 10.0.22 or higher than you can use code like this in your print widget

const fileReference:FileReference = new FileReference();
             fileReference.addEventListener(Event.COMPLETE, removeCur);
             fileReference.addEventListener(Event.CANCEL, removeCur);
             fileReference.addEventListener(IOErrorEvent.IO_ERROR, removeCur);
             fileReference.addEventListener(SecurityErrorEvent.SECURITY_ERROR, removeCur);
    fileReference.save(myPDF.save(Method.LOCAL,"",Download.INLINE,"myPDF.pdf"),"map.pdf");

Do you need to be using the Flex 4 SDK to use FileReference.save? In the 3.5 SDK help it shows the FileReference object as having a save method but when I try to use it I get an error:

1061: Call to a possibly undefined method save through a reference with static type flash.net:FileReference

No, you just need to require Flash Player 10. In the Compiler section of your project's properties, change "Require Flash Player version" to 10 0 0.

In my case I incorrectly installed the .Net piece...missed copying a file into the proper directory. This was pointed out by a colleague who looked at it for 5 minutes yesterday. Once that structure was repaired, things work fine!

I will keep things in mind for being able to do it another way, though, Robert. Thanks!

Thanks Dasa, that was an easy fix!

Robert,

What is the "removeCur" in this code? I am trying to use your code with a similar alivepdf widget and flexbuilder just sees "removeCur" as an undefined property.

Thanks.

Joshua,

The RemoveCur is just a simple function that I have that will remove the busy cursor that I set when the pdf export begins. You can delete all those event listeners if you want to.

Thanks. I had it working before without them, but I wasn't sure if those lines added something. What I'm really trying to get to is have the user be able to either save the pdf or choose to print directly. (Basically what the "Print Map" widget is like on your Flexviewer 2.0 application (although mine is still 1.3).

I tried to implement as suggested by you but
var fileReference:FileReference = new FileReference();
             fileReference.addEventListener(Event.COMPLETE, removeCur);
             fileReference.addEventListener(Event.CANCEL, removeCur);
             fileReference.addEventListener(IOErrorEvent.IO_ERROR, removeCur);
             fileReference.addEventListener(SecurityErrorEvent.SECURITY_ERROR, removeCur);
fileReference.save(myPDF.save(Method.LOCAL,"",Download.INLINE,"myPDF.pdf"),"map.pdf");

it result an error:
Error Message:
"Certain actions, such as those that display a pop-up window, may only be invoked upon user interaction, for example by a mouse click or button press."

Shafi,

Just like the message is telling you you have to call this code directly from a mouse click like a button in a widget or a context menu. It can not be called from any other portion of code that call on another function before it opens the file save dialog.

Hi, Robert
I added button click to load the printPDF function, but I have to click the button twice to open the save as window. Is something wrong with that?
Thanks,
Amy

private function PrintPDF():void
   {
    generatePDF();
    var fileReference:FileReference = new FileReference();
    fileReference.save(myPDF.save(Method.LOCAL,"",Download.INLINE,"myPDF.pdf"),"map.pdf");

   }

Amy,

The generate pdf function is taking the focus which forces you to have to click the button again to give the focus to the save method. You need to have a button for generate pdf and then then have the user click a button that only has the file reference code.

Got it, thank you so much.

Hi,
I've been reading the latest threads regarding the PDF Prinitng widget, along with the latest Flex API. I've also implemented a PDF widget which utilizes Robert's code. Once the widget displays and I click "print pdf" I get the following errors:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
at org.alivepdf.fonts::AFMParser/readAFM()[/Users/adobe/Desktop/AlivePDF/src/org/alivepdf/fonts/AFMParser.as:92]

at org.alivepdf.fonts::EmbeddedFont()[/Users/adobe/Desktop/AlivePDF/src/org/alivepdf/fonts/EmbeddedFont.as:39]

I am using the latest AlivePDF.swc library, but I can't seem to troubleshoot the error. Looks like my application can't access the font file. Can you guys lead down the right track on this one.

Thanx
Frank

Frank,

Here some code that may help:

[Embed(source='assets/arial.ttf', embedAsCFF='false', fontName='myArial', mimeType='application/x-font')]
   private var font1:Class;
var myCoreFont:IFont = new  CoreFont (FontFamily.ARIAL);
     myPDF.setFont(myCoreFont,8);

Of course this assumes you have the arial.ttf in the assets folder of your project.

Robert,
I think that might be my problem. I commented this section of code due to errors during compilation.

/*    [Embed(source='assets/arial.ttf', embedAsCFF='false', fontName='myArial', mimeType='application/x-font')]
   private var font1:Class;

   [Embed(source='assets/esri_40.ttf', mimeType="application/octet-stream")]
   private var fNorthArrow:Class;

   [Embed(source='assets/esri_40.ttf', embedAsCFF='false', fontName='esriNorth', mimeType="application/x-font")]
   private var fNorthArrowFont:Class;

   [Embed(source="assets/b617d5849ea5bacc44c29fc0d4c2bed6_esri_40.afm", mimeType="application/octet-stream")]
   private var afmNorthArrow:Class;   */

How can I get a hold of these missing .ttf files or is there a work around?

Thanx.

Frank,

You should be able to search your machine and find these in the windows fonts folder.

Thanks Robert.
The only error now is referring to esri_40.afm. I could not find that one.

[Embed(source="assets/b617d5849ea5bacc44c29fc0d4c2bed6_esri_40.afm", mimeType="application/octet-stream")]

I forgot that I had to create that one.
