CF10 Flash Remoting

• I can trigger a flash remotely from the EOS Utility?

  Hello. I am a total newbie, so forgive me if my question is very basic or confused.

  I just bought a Rebel T5i (literally, my first ever buy SLR) and have been using the EOS utility to be able to "live view" on my desktop screen. It seems to work pretty well.

  However, I am interested with the addition of a flash remotely as a Speedlite flash, to be placed between the subject and background. Will be a remote flash correctly from live view EOS Utility work? Should it be a Speedlite flash, or can it be a third flash?

  I'm not too considered with flash quality as much as I just want to be able to take pictures with the EOS Utility live view, with the remote flash fires to light a backdrop behind the subject.

  Thank you!

  As Ernie points out... the computer simply tells the camera when taking the shot.  If the camera has a flash, then the camera fires the flash when he takes this one.

  But your question is loaded with some nuances and it is not just a direct response.

  A Canon T5i has the ability to fire distance a Canon speedlite if three conditions are met:

  (1) the flash must support E - TTL

  (2) the flash must support E - TTL mode 'slave' (and that the mode must be enabled - it will not be enabled by default.)

  (3) flash must be direct "corridor" between the camera and remotely.

  The camera itself needs to be said that it is in a mode where the flash pop up on the device will work as a 'master' to trigger a remote flash.

  But you mentioned that you wanted to put this flash to distance between a subject and the context - which implies that 'line of sight' is not possible.  Who calls other WIRING.

  You can learn a lot about flash systems Canon E - TTL of the "Manual of the Speedlighter" (by Syl Arena), but this book has not been updated (as far as I know) to include systems flash triggered by Canon's new radio.

  To do this with the Canon gear, you want a transmitter of radio ST-E3-RT (which amounts to the hoof as a flash camera) and then use a flash Canon Speedlight with a suffix 'RT' such as flash 600EX-RT (flash light) or the new 430EX III - RT.  All products of "RT" communicate by radio and do not require a line of sight direct.

  It is also possible to do with budget gear..., you can get a pair of transceivers trigger... we're going on the device and the other goes hand in hand with the remote flash.  These radio triggers are not "E - TTL", which means that the camera and the flash will not be able to communicate and negotiate the amount of energy must be used for shooting "on the fly" (as can an E - TTL flash).  This means that you will need to manually set the power level you want to use.

  Having to use manual flash should not be terribly difficult to learn.  The flash and the camera usually automatically set your power level, as it would for E - TTL flashes.  You control the light, by adjusting the power level of the flash (manually) or by moving the flash closer or away from your topic (or using the flash light modifiers) more, or by adjusting the opening of the camera.

  This works well in a situation of type 'studio', where you can control the power settings.  But for photography of the 'event' where you have to shoot on-the-fly and you "-over" If rush you the shot, you have to learn the flash behavior before the shooting. For me, it means creating a table which indicates (for any given on the flash power level) f-stop, should I use any flash-to-subject distance given.  I used usually non-zooms at this time, but I knew that, for example, a shot of 'dance' a couple of size - up to (what we call a "half coup" because we have only half upper body of our subject) was f/16 at ISO 100.  A length of 3/4 shot (essentially from the knees upwards) was f/11.  A shot of 'length' was f/8, and a group shot can be f/5.6 or even f/4.

  It necessary to the good days past tests and completing such a table.  You won't have the time to refer to such a table, but I mentally memorized by distance because the subject framing was a good consistent indicator of distance.  (it is a bit more complicated with zooms because you can change the subject framing without changing the distance).   But in the end, you find yourself in a situation where you go back to a subject at a demonstration, the frame of the shooting, set the aperture value and capture the image and know that you nailed the exposure even if the whole system is manual.

  There are a lot of tutorials on the use of the manual of flash and inexpensive triggers to the Strobist blog (strobist.blogspot.com).

  I use the Canon system.  I use the Canon ST-E3-RT trigger a few flashes 600EX-RT.  The system is rock solid... it always works.

• Flash Remoting works does not in CF 10

  Have us use Flash Remoting for years and now find while testing 10 CF on a development server, it no longer works.

  In particular, I get a 404 error when you try to access to https:// {ip address} / flashservices/gateway.

  I have already confirmed that remoting is enabled in the administrator and follow the steps in the documentation (http://help.adobe.com/en_US/ColdFusion/10.0/Installing/WSc3ff6d0ea77859461172e0811cdec1896 9 - 7ffa.html).

  Any advice?

  It may seem absurd, but the solution was to add a slash ("/") at the end of the URL of the gateway:

  https:// {ip address} / flashservices/gateway.

  This was not required in earlier versions, but apparently it is in CF 10.

  Once I added this character to my code, Flash Remoting has worked in my application, once again.

• ussue with application.cfc in flash remoting

  < cfproperty

  output = "false".

  Hint = "I defined the parameters of the application and managers of events." >

  Hi, im using flash remoting to call CFCS and I want to use the application.cfc to determine the environment (the APPLICATION.environment defines a DSN that is used in flash to CFC calls).

  However, whenever I call a cfc with the app.cfc, I get a CF error that I can't debug because CF builder is uselss to connect to debuggers. Any ideas?

  <!-define the application. ->

  N ° the scope is used to access the application-scope variables.

  I think you should read the operation expanded in the CF.  Read this entire section of the documentation:

  http://help.Adobe.com/en_US/ColdFusion/9.0/developing/WSc3ff6d0ea77859461172e0811cbec22c24-7ff2.html

  I can't guess where in your code you put the CFDUMP, so I can't really comment on the rest.

• THEY Flash Remoting request limit introduced with Coldfusion 9?

  Hi all

  We've just been our Coldfusion servers since 8.01 CF CF 9. They run Win 2008. On servers that provide the Flash remoting backend for a Flex application, we provide, we ran into trouble.

  After upgrading CF 9 noticed that during busy when many customers Flex have been completed, we connect, we seemed to have a strict limit of 25 Flash Remoting running queries, despite the much higher limits (in fact 150) in CF Admin.

  We first thought that it was a problem with the fact that Blaze DS now ships with CF 9 (rather than a separate installation) we decided to roll back the installation of CF 9. This, unfortunately, has not worked and we were always stuck with out strict limit of 25 applications for Flash Remoting.

  Then looking at IIS we noticed the CF9 ISAPI filter was installed yet (after we ran the part of installing Web Service Configuration). Who took the CF 8 were re-run and all of a sudden the strict limit Flash Remoting has disappeared. So it seems that it might have had something to do with the wsconfig CF 9 (C:\ColdFusion9\runtime\bin\wsconfig.exe)

  If anyone has had this problem or does anyone know where these hard limits are configured in IIS?

  Any help appreciated!

  @ciaranarcher (and other interested parties in the present), I posted what, in my view, is the solution on the stackoverflow website where it had also posted the question:

  http://StackOverflow.com/questions/3037390/IIS-Flash-Remoting-request-limit-introduced-wit h-coldfusion-9

  Let us know (here and there) if it is the solution for you (and others). Thank you.

• Flash remoting and session management

  Hello

  I'm developing an application in Flash and AS3 and I use ColdFusion 8 for flash remoting. Some screens will be used by only 1 user. I googled many times and I had a few pages containing topics 'OnSessionStart', 'OnSessionEnd' and 'OnRequest', I tried to use my CFCs but makes no sense. I want to erase the State of the use of the screen in my application. If I can catch the event 'session-end', I can clear the field of use of database. So if a user closes the browser window not correctly, the value of the field will be handed over to zero and one other user can use the screen safely.

  Help, please. Thank you.

  How do you currently user and session management, then? It is entirely in Flex? To make the session management in ColdFusion, you must have either an Application.cfc (or an Application.cfm... Application.CFC is recommended, however) file in the same folder as the portion of your application ColdFusion. The CF server will be automatically call Application.cfc before you run some of your pages on cfc or cfm and run automatically to the SystemFramework, OnSessionStart, OnRequestStart, OnRequest, OnRequestEnd, OnSessionEnd, OnApplicationEnd or OnError methods you defined in the Application.cfc file. SystemFramework fires when the CF application is first started, OnSessionStart is triggered whenever a new session is started, OnRequestStart is triggered at the beginning of each page request, etc. You don't need to define all the... in my applications, I used SystemFramework, OnSessionStart, OnRequestStart, OnSessionEnd and OnError defined. There is also no need to worry when or how call one of these methods the CF server that will do for you. All you have to do, is essentially, describe what you want to happen when a session starts or ends, when a page request occurs when the application starts, etc. and CF will call the appropriate method that you hit every event. A simple Application.cfc file might look like this:

  
     

  
     
     
    
     
     
     
         
         
         
     
     
     
     
         

  
         
     
     
     

  
         
        
         
     
     
  

  Does that help? Also, I would recommend that you read the section of the livedocs framework of the CF Application and how to manage the session data and application.

• Flash remoting vs. Flex vs CF

  Reading the product documentation, it's really hard to say what the CF has and what Flex and the server to access remote flash would provide on CFMX7. Does anyone have a difinitive answer on that?

  If you use flex or flashforms, 'no', but I guess that really depends on what you
  you want to accomplish. w/cf7 you get painless flash remoting out of the box, free.
  I don't know enough about the flash to tell flash remoting is not worth.

  Flex itself is free but the flex builder ('IDE' built on eclipse) fees
  about $500US, but I think that it is worth if you do a lot of this kind of interface
  work. If you are just getting into this kind of thing that I would say flexible
  instead of "raw" flash or CF flashforms.

• Problem by changing Flash Remoting to Webservice

  I have a request using flash remoting with the Flash Remoting enabled under the Flex option on the administrator see I need to move this application to a server that has flash remoting, but not the new Flex option.
  
  The CFC returns a query, when I use http://hostname/flex2gateway/ the event.result is returned as an ArrayCollection collection FlashRemoting (that's what I want because I'm adding to a DataGrid, but when I change to webservice the event.result is of type array.) When I use flash remoting changing endpoint at http://hostname/flashservices/gateway
  I'm getting a TypeError: Error #1034: Type coercion failed: cannot convert Object@4e2a4c1 in mx.messaging.messages.ErrorMessage.
  
  Basically, I need to know how to call a webservice or flashremoting using http://hostname/flashservices/gateway , which returns a query for use with a datagrid control. If anyone can give me some advice, I'd appreciate it.

  Web Services uses types of basic, arrays, strings, etc.
  Communication to remote/Remote objects using these basic types with
  complex data types, works of art, ArrayCollections, etc..

  When you come back to the table of your web service, cast to an ArrayCollection collection
  and whether you use it before you use it.

  var MonTableau = event.result;

  myAC:ArrayCollection = new ArrayCollection (myArray);

• Flash Remoting on local development box

  I really hope someone can help with this. I googled to death for two days and found nothing. I'm at my wits end. I installed CF8 on Windows XP Pro on IIS5.1 with several sites. I am also using Flex 3. I'm trying to get a simple helloworld application to work with a flash remoting CFCs. When I run it, in the error dialog box, I get this error include:
  
  [Error CPP faultString = "Send failed" = "Client.Error.MessageSend" faultDetail ="faultCode" Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: failed: url: ' http://localhost/flex2gateway/' ' ]
  
  I tried to connect to http://localhost/flex2gateway/ via the browser and I get a page not found message. Note that I had to change the root directory in IIS to point to my new site, so it is no longer the default site. If I change back to the default, I find this file. I can't understand for the life of me how to get this url to work in the new site? Surely someone else has several sites and knows how to solve this problem?
  
  Thank you!

  Hallefrickinglujah! I finally got to work. I'll post the answer here to help someone in the future. For sites you create AFTER installing CF8, you must create the JRunScripts virtual directory as described in this article: http://www.frenches.com/blog/index.cfm/2007/5/7/Flex-Coldfusion--Dont-make-me-have-to-sepa rate - you two

  Make sure you just after you create it, you go into IIS and give permissions on Scripts and executables - run it is a drop down in the properties of the virtual directory dialog box. Good luck!

• Check the version of Flash remotely

  Does anyone know how to write a script that can remotely check the latest version of Adobe Flash on several workstations?

  I found a solution for this. Just run a batch file to run the following command:

  SET VAR = %1

  orders Filever /ad '\\%VAR%\C$\WINDOWS\system32\Macromed\Flash\flash*.ocx '.

  You will need to copy the "filever.exe" command in your System32 folder and % VAR is the name of the remote workstations.

• Grid master detail with flash remoting

  I tried to fill a detail grid based selection of main grid, I finally got the second grid (detail) to fill when I chose a recording of the first grid (master), unfortunately I lost the fields of text entry for the master record to which I am bound by the master grid. now, I'm just the details records.
  The two grids are populated by 2 different applications residing in the same CFC.
  
  I start by filling the master grid (userGrid), then when a line is selected I spend the primary key of the selected lines to the function that calls the query of detail in the cfc. This query selects only records where the master primary key = the foreign key in the secondary table.
  
  It is an example of the code that is in the script tag, which deals with the grid:
  
  var responseHandler:Object = {};
  
  var userGrid:mx.controls.DataGrid = userGrid; (this is the main gate)
  var userIdGrid:mx.controls.DataGrid = userIdGrid; (it's the detail grid)
  
  responseHandler.onResult = function (results: Object): Void
  {userGrid.dataProvider = results.item;}
  _root.setmode ('add');
  mx.managers.CursorManager.removeBusyCursor ();
  }
  
  responseHandler.queryUserid_Result = function (results: Object): Void
  {userIdGrid.dataProvider = results.item;}
  _root.setmode ('add');
  mx.managers.CursorManager.removeBusyCursor ();
  }
  
  On the form load call the getData() that fills the Mastergrid by using the master in the CFC query - it works.
  The getData() looks like this:
  
  public void getData (): Void
  {
  var qArgs:Object ();
  < cfoutput >
  qArgs.status = "#session.status #";
  < / cfoutput >
  _Global.listingService.queryAll (qArgs);
  _root.setmode ('add');
  mx.managers.CursorManager.removeBusyCursor ();
  }
  
  
  The main gate makes the call to the second grid (getUserid() in the event onchange, the PKNO column is the primary key):
  < name cfgrid = "userGrid"... onchange = "userGridChanged (); getUserid (userGrid.selectedItem.PKNO)" >
  
  The getUserid () looks like this:
  
  public void getUserid(pkno:String):Void
  {
  var userArgs:Object ();
  < cfoutput >
  userArgs.pkno = pkno;
  < / cfoutput >
  _Global.listingService.queryUserid (userArgs);
  _root.setmode ('add');
  mx.managers.CursorManager.removeBusyCursor ();
  }
  
  This function is to fill the grid of detail with correct data. When I select a line of the master userGrid.
  
  The right panel has the textinput to the master record fields that are related to the master grid-userGrid. Below these textinput fields, I have the detail grid - userIdGrid, which can contain 1 or more lines. I can get one or the other to fill, not both.
  
  Is there a problem with the resultHandlers each specifying the .dataprovider?
  
  Any help would be greatly appreciated.
  
  Thanks in advanced for any help.

  You call setMode() much, by chance you're wrong data clearing it when you do not expect.

• The Canon 70 d remote flash trigger

  Which Canon speed light will work off camera and be triggered by the functionality of firing the flash in camera remotely?

  The native (built-in) flash trigger IS.  This is an optical trigger and requires line of sight to the off-camera flash.

  The 430EX II can be a 'slave' (flash remotely triggered), but may not be a master.  The 580EX II can be a master or slave.  600EX-RT can also be a master or slave (and can no optical or by radio but radio requires a radio trigger - sells Canon a dedicated radio ST-E3-RT trigger or an another 600EX-RT flash can be used as a master/trigger.)

  The built-in flash uses pulses of light (visible light) to communicate with slaves and relay instructions.  It is not infrared or radio.  But the receiver in the slave flashes is on the lower part of the body (not in the flash head upwards).  The front of the lower part of the body has a tint red Panel that resemlbes what you would see on an infrared remote - leading people to assume that it is IR it isn't visible - IR

  If the remote light does not pull when the flash on the camera goes off then lower unit may not have good lighting of the view.  Keep in mind the 430EX II 580EX II and 600EX-RT that all have a flash head that can tilt AND turn left and right.  This means that you can rotate the lower part of the body of the flash so that it points to your camera, but always turn the head so that it points toward your subject.
