• Verify mail server connection programmatically

  - by Sergii

  I'm using custom SMTP servers and would like to verify the connection when user enters his own server credentials. Exactly the same type of check as Adobe CF and Railo allow to do when adding mail server. Sure, this does not guarantee that delivery will be working, but at least to check that entered server/username/pass are valid. I can see one tricky way: try to send the email with cfmail and check the mail log. But I believe that it can be done with more elegant. Is there any Java library available with standard ACF/Railo distro to help me? How would I use them? Examples are highly appreciated. Thanks in advance.

• Can SVG render partially if gzipped and chunk-transferred?

  - by Scott Stafford

  Hi - I have some large, dynamically generated SVGs that are being served over a relatively slow internet connection. I'm trying to optimize them to be viewable as fast as possible. If I set the server to Content-Encoding: gzip and Transfer-Encoding: chunked, will any SVG viewers take advantage of that and render it partially, as it is transferred? If not, are there other ways to get it to render as-it-streams? I could break it up into several SVG pieces but that will be a lot of work, I was hoping for server settings... The most common users use IE7 with the Adobe SVG Viewer plugin. I doubt it matters but I'm serving with C#/ASP.NET and IIS6.

• Can I fill in an encypted PDF with iTextSharp?

  - by Cmpalmer

  I have a fillable, saveable PDF file that has an owner password (that I don't have access to). I can fill it out in Adobe reader, export the FDF file, modify the FDF file, and then import it. Then I tried to do it with iText(Sharp). I can't create a PdfStamper from my PdfReader because I didn't provide the owner password to the reader. Is there any way to do this programmatically or must I recreate the document? Even using FdfReader requires a PdfStamper. Am I missing anything? Anything legal that is - I'm pretty sure I could hack the document, but I can't. Ironically, recreating it would probably be ok.

• Hidding a Flash SWF upon loading

  - by Rudy

  Hello, I have a question that is probably very simple, but I cannot find an answer here or on Google. I am loading a SWF in an HTML page the following way (using JavaScript): AC_FL_RunContent( "src", "${swf}", .... "type", "application/x-shockwave-flash", "pluginspage", "http://www.adobe.com/go/getflashplayer" ); I have tried to add the line: "style", "visibility: hidden" But it has not worked. I can later on make it visible or hidden using: document.getElementById("flash").style.visibility = "hidden"; But I would like to have the flash invisible and make it visible later on, but by adding a parameter in the AC_FL_RunContent. I hope someone can please help me. Thanks a lot. Rudy

• Using Flex to keep local SQLite database in sync with live server database

  - by DaveC

  I want to create a Flex 3 application running in Adobe Air that accesses an SQLite database and I need to keep this database in sync with an SQL server 2005 database running a website. Is this something that Flex supports or is it going to be a custom script? Also, has anybody done anything like this? Edit: The synchronisation can be done on a daily basis rather than real time. The data will be read only from a front end perspective with a CMS to do updates on the website.

• Actionscript: Why is drawRoundRectComplex() not documented?

  - by Chunk1978

  in studying actionscript 3's graphics class, i've come across the undocumented drawRoundRectComplex() method. it's a variant of drawRoundRect() but with 8 parameters, the final four being the diameter of each corner (x, y, width, height, top left, top right, bottom left, bottom right). //example var sp:Sprite = new Sprite(); sp.graphics.lineStyle(1, 0x000000); sp.graphics.drawRoundRectComplex(0, 0, 100, 50, 10, 20, 0, 10); addChild(sp); this seems to be a pretty useful method, so i'm just curious if anyone knows of any reasons why adobe chose not to document it?

• Submitting a form on 'Enter' with jQuery?

  - by b. e. hollenbeck

  I have a bog-standard login form - an email text field, a password field and a submit button on an AIR project that's using HTML/jQuery. When I hit Enter on the form, the entire form's contents vanish, but the form isn't submitted. Does anyone know if this is a Webkit issue (Adobe AIR uses Webkit for HTML), or if I've bunged things up? I tried: $('.input').keypress(function(e){ if(e.which == 13){ $('form#login').submit(); } }); But that neither stopped the clearing behavior, or submitted the form. There's no action associated with the form - could that be the issue? Can I put a javascript function in the action?

• Eclipse users: Do you use Aptana too?

  - by Glenn

  This San Mateo development company makes a freely downloadable convenient packaging of many plugins for Eclipse called Aptana. I was recently in an environment where Aptana came pre-installed. Not only is it a good IDE for RoR, it also does a somewhat decent job (sans debugging) for PHP, Python, HTML, CSS, and Javascript. According to their own web site, their IDE also supports Adobe Air and the iPhone. If you are currently using Eclipse, then do you also use Aptana too? What, if any, are the drawbacks to using Aptana?

• Generating PDF files from .NET by using standard .NET GDI printing classes

  - by Philippe Leybaert

  I'm looking for a way to generate PDF files using the standard PrintDocument and Graphics (GDI) classes in .NET. As far as I know, the only way to do that is by printing to a PDF printer. The problem is that a PDF printer driver always asks for a filename, but I need to control the filename from my code. Using a PDF library like PDFSharp or DynamicPDF is not an option, because they all provide their own API for generating PDF files. I need this for an internal application, so dependencies are not a problem. My question is simple: is there a way to control a printer driver (Adobe Acrobat, PDFCreator, ...) in such a way that a filename can be specified and the user is not prompted for anything?

• PostScript versus PDF as an output format

  - by Brecht Machiels

  I'm currently writing a typesetting application and I'm using PSG as the backend for producing postscript files. I'm now wondering whether that choice makes sense. It seems the ReportLab Toolkit offers all the features PSG offers, and more. ReportLab outputs PDF however. Advantages PDF offers: transparancy better support for character encodings (Unicode, for example) ability to embed TrueType and even OpenType fonts hyperlinks and bookmarks Is there any reason to use Postscript instead of directly outputting to PDF? While Postscript is a full programming language as opposed to PDF, as a basic output format for documents, that doesn't seem to offer any advantage. I assume a PDF can be readily converted to PostScript for printing? Some useful links: Wikipedia: PDF Adobe: PostScript vs. PDF

• Will a CF code run on regular server?

  - by Joann

  I am tasked to integrate a CF code(about 70 lines) into our site then configure it to communicate to another site's server. However, our hosting site is just a typical server without CF support. Will the code run? All I know is that CF is Adobe's version of PHP and ASP. I have no experience coding it. Could you please enlighten me? From what I gathered from the internet, you have to have a CF server in order to run a CF code but the resources seem scarce. I just need someone knowledgeable to verify...

• MIDI on Android: Java and/or AIR libraries

  - by yar

  I've been contemplating (re)building an app on iPad for some time, where I would use objective-C and DSMI to send MIDI signals to a host computer. This is not bad (I mean, except for actually writing the app). Now I'm contemplating perhaps developing the app for Android tablets (TBA). In Java, what options are available for MIDI message communication? I'm quite familiar with javax.sound.midi, but then I would need a virtual MIDI port to send messages to the host. On the other hand, if the app were done in Adobe AIR, what options would I have available for communicating with MIDI? Obviously another option is to send/receive messages over a TCP/IP socket to a Java host, and talk that way, but it sounds a tad cumbersome... or perhaps not? DSMI does use a host program, after all.

• How can we avoid packet missing in UDP Flex?

  - by Naveen kumar

  Hi all, I'm trying to send large files using UDP Adobe air to CPP. While transferring large files some packets are missing. How can I retrieve the missing packets data? I'm first of all connecting client(air) with server(cpp) using tcp. After connection establishment I'm starting file transfer. I am planning to get the file missing data using tcp and then resending the missing packets using tcp. Can anybody tell me how can i come to know which packets are missing while transferring. Thank you.

• ASP.net - Crystal Reports exporting to PDF adds the letter "i" to certain words randomly

  - by CraigF

  We are using Crystal Reports to generate pdf's of customer bills (from a CR template). It works fine except the engine seems to be adding the letter "i" to random words in the output. Certain alignment problems are also evident (words overlapping etc). Standard fonts are being used. We are using .net 4 and C# linked to the 10.5 CR assemblies. Latest version of Adobe Acrobat reader is installed on the server. We have now tried this via 12.2 CR assemblies with the same results. We have also tried multiple .rpt files with the same results.

• Why does my PDF ask for a password after being retrieved from Visual SourceSafe?

  - by Schnapple

  PREFACE: Yes we're moving away from VSS in the next few months. One of my web projects contains, as one of its files, a PDF. The PDF on our QA site is being pulled from VSS. A QA tester recently told me he's being prompted for a password when he tries to open it. VSS says the file I have on disk is different than the one it has, so I updated it, but afterwards it's still being shown as different. So basically VSS is mangling my PDF and the results are so wobbly that Adobe Acrobat Reader is confused and thinks it has a password. I've tried adding it as Auto-Detect and as Binary. Same results. Why does my PDF ask for a password after being retrieved from Visual SourceSafe and how can I prevent it?

• Prefered method for looping sound flash as3

  - by Brian Heylin

  Hi there, I'm having some issues with looping a sound in flash AS3, in that when I tell the sound to loop I get a slight delay at the end/beginning of the audio. The audio is clipped correctly and will play without a gap on garage band. I know that there are issues with sound in general in flash, bugs with encodings and the inaccuracies with the SOUND_COMPLETE event (And Adobe should be embarrassed with their handling of these issues) I have tried to use the built in loop argument in the play method on the Sound class and also react on the SOUND_COMPLETE event, but both cause a delay. But has anyone come up with a technique for looping a sound without any noticeable gap?

• Trouble getting Flash socket policy file to work.

  - by Alex

  Basically I'm using Flash to connect to a Java server. Despite my Java application replying to the , in the Flash debug log it lists (not sure about the order as there are lots): * Security Sandbox Violation * Connection to 192.168.1.86:4049 halted - not permitted from http://127.0.0.1:8888/Current/wander.swf Warning: Timeout on xmlsocket://192.168.1.86:4049 (at 3 seconds) while waiting for socket policy file. This should not cause any problems, but see http://www.adobe.com/go/strict_policy_files for an explanation. Error: Request for resource at xmlsocket://192.168.1.86:4049 by requestor from http://127.0.0.1:8888/Current/wander.swf is denied due to lack of policy file permissions. What I don't understand is, the server (port 4049) receives the request, outputs the policy file and then closes the connection, surely it shouldn't time out? The policy file I'm using is: <?xml version="1.0"?> <cross-domain-policy><allow-access-from domain="*" to-ports="*" /> </cross-domain-policy>

• possible to recreate xml out of ActionScript?

  - by Andy

  Hi, I got stuck with an SWF which has ActionScript in it and should use some xml. The problem is, I cannot edit the SWF by decompiling it and compile it again, it simply doesn't work... Adobe Flash CS4 rebuilds the thing, but after I press CTRL+ENTER I get a lot of runtime errors (probably something to do with AS <- AS2 <- AS3 and don't know how to fix that). So the question is: can I reconstruct how the xml should look like? I am able to view all the actionscript code with Flash Decompiler Gold and ain't gettin much smarter. Maybe I could post the code if someone desire it. thanks

• Flex4 Application state in a custom component

  - by itarato

  Hi, I'm porting my Flex3 app to Flex4 (FlashBuilder4). I get the whole new state concept, except one thing. In a custom component (separate mxml file) I'm using the main level Application's state. In Flex3 it was: <mx:State name="only_view_mode"> <mx:RemoveChild target="{myComponent.button1}" /> </mx:State> In Flex4 it should be something like that: <mx:State name="only_view_mode" /> and <mx:LinkButton id="button1" excludeFrom="???" /> My question is: how can I access to an Application state from a component? I checked the official reference (http://www.adobe.com/go/learn_flex4_alldocumentation_en) and Google of course but without any success. Thanks in advance

• where does the professional sheen of a GUI application realistically come from?

  - by JW

  I have been playing around with php-gtk recently and in the past I have experimented with Java to make GUI 'hello world' apps. However both these types of applications have had a bit of a clunky (almost childish) look and feel to them. I cannot deny that they are handy for making apps for in-house use (and I totally respect the amount of community effort that goes into these projects). But I would not necessarily be proud to sell it as a commercial application with a price tag of, say, £450 or £1,000. If I wanted to make an application that had the look and feel of, say, Firefox for Windows, or Adobe xyz, what GUI/language should I use? Is the 'professional sheen' or smart look and feel down to the designer or is it the case that, no matter how good a designer is, picking the right GUI framework is essential to get that look?

• Flash content works on direct link, but not when inserted into html?

  How come http://www.zolomon.com/wptj/wp-content/themes/default/polaroid.swf works perfectly but not when implemented at http://www.zolomon.com/wptj/?page_id=8 ?

• flex chat/telnet application send/receive same window in TextArea

  - by Renassaince Geek

  Hi there, Just wanting to know if anybody has seen an example of a telnet/chat or other console like FLEX application where you can use the same TextArea as input/ouput area. I've been trying to modify the app at: http://livedocs.adobe.com/flex/3/html/17_Networking_and_communications_8.html but so far, computer says no. All the implementations I've seen use a combination of TextInput and TextArea. The challenge is that we'll be using this app to telnet into some old routers and we'll need to do a fair amount of copy/pasting. Based on what I've seen, it seems that I would need to point the mouse into the TextInput in order to be able to right click and paste, which is not very sleak..... Your thoughts, Fran

• Converting Flash frame to JPEG

  - by dhorn

  We are attempting to convert a flash frame into a JPEG without using the Flex SDK or other adobe tools. Right now, we have a flash file that passes binary data over to a .cfm page, which uses the following code to change the headers: <cfset var = GetHttpRequestData()> <cfcontent type="image/jpeg"> <cfheader name="Content-Disposition" value="attachment; filename=#url.name#"> <cfoutput>#var.content#</cfoutput> This code is producing some strange results. Basically, it renders as an image, and I can "right click - Set as desktop background", but I cannot save the image any other way, as it simply saves the contents of the HTML Source. So, questions: 1) Is what I'm trying to do even possible? 2) If so, any suggestions? Thanks guys.
