How do i get a Widget to read from CP4's Library (holly grail of widgets)
Hi All
I'm having a little trouble with one of my widgets. The widget basically creates a simple image tween inside CP4. (something i think is sorely missed in the CP franchise)
To make this widget reusable I need to be able to replace the image with appropriate image depending on the subject matter.
I have found a number of ways of doing this but they all have their own problems..
1) Read an image from an external file - the problem is that IE6 (the customers default browser) throws a flash security error. (no errors in firefox suprise surprise)
2) Publish the widget flash file with multiple images in its flash library - The Problem is Captivate eats away your RAM. This is because CP4 doesn't dump the the widget out or RAM at the end of each slide. And if your using multiple instances of a large widget in the one program.. Get ready for a rude shock by the end of your movie!
3) Store the images for your widget in CP4's internal widget XML file by encoding the bitmap data into a base 64 string - (Ingenious YES) but does it work ... Sort of.. the problem here lies (we think) in the max possible length of the internal XML file.. We have been crashing captivate when we import more then about 7 images into the XML string.
FINALLY THE QUESTION!!
Does any know how to read / use CP4s library using a widget? We would prefer a solution in AS3 but beggars cant be choosers...
Cheers

Hi Aquil0,
If there was any way to access the library, I'd think it would be through a Captivate Variable (Accessed via movieHandle I would guess).
Pipwerks has a rather extensive list of Captivate Variables, but none of the ones listed there seem to access the library. You could try following the pattern and seeing if 'cpLibrary' or something similar exists.
I'm very interested to see if this problem can be fixed, because this is probably one of the main roadblocks in creating a drag and drop question widget. I had thought before that you would have to pull in a image file from the server, and I'm a bit disappointed to hear it doesn't work for IE6.
Just out of curiosity. Could you share how you passed the image information into the widget XML? Anything regarding Widget parameters generaly interests me.

How do I get Labview 7 to read from RS232
I have a power meter that sends output to a serial port. I need to get that output into Our LabView program. We have the Serial code from the power meter. It sometimes works when the lightbulb icon is clicked, otherwise it does not. ?
Hi,
You said that the code that you currently have works when you have Highlighted Excution on (light bulb); this leads me to belive that you have a timing issue. You can start by adding saome delays between the read and write functions, this way yuo give enough time to the instrument to respond to each command.
Please let me know if you have more specific questions on this.
Regards,
Juan Carlos. -

On my Mac Pro how can I get voiceover to start reading at a specific point in a document, and then continue on to the next paragraph and so on? Thank you. Ed
Welcome to the Apple family!!!!
How can I cause the VO cursor(box) show-up/start?
Press Control-Option and F5. The F5 key is located on the top row of keys 6th key over. This is a toggling "Keyboard Shortcut" for turning VoiceOver on and off.
How can I move the VO cursor to various sentences or paragraphs of an article and have it start reading ... and perhaps even continue reading on to the next paragraph(s) ... even to the end of the article?
How to read a website with VoiceOver
Step 1: Go to the Website
A quick keyboard shortcut is Command-L. This will jump you up to the address bar. Start typing where you want to go. i.e "www.thewebsite.com"
Step 2: Working with Webpage
VoiceOver will automatically start reading the website. You can pause the speech by hitting the 'Control Button'.
If VoiceOver does not being reading the webpage, then you might have to "Interact" with it. If VoiceOver say "HTML Content" then press Control-Option-Space-Down Arrow to interact with the webpage.
Use Control-Option-Right Arrow to move throught the website. This will speak "EVERYTHING" on the page.
Most website that I've found have their articles labeled as 'Heading'. You can jump from heading to heading, by pressing Control-Option-Shift-H.
If you'd like an itemized alphabetical listing of the site, press Control-Option-I
Press Control-Option-Space on the link or article you want to view.
Step 3. Reading from Top to Bottom
Once you found and clicked on the the article/link, use the same 'Heading' command, Control-Option-Shift-H to find the title.
After finding the title, press Control-Option-A will start reading from the title on.
Note: If there are any other items (ads, pictures, etc) it will read those too.
Tip: You might be able to activate a feature called the 'Reader'. The Reader isolates the article and elimanates the ads The keyboard command is Shift-Command-R. You can also find it in the Menu Bar (Command-Option-M) under the word 'View' then 'Show Reader'.
I am using a MACPro with OSX, probably Mavericks 10.9 (where would I look to see if that is the correct information?)
You can find this information under the 'Apple menu' in the Menu Bar. To access the Menu Bar, press Control-Option-M.
Go to Apple Menu > About This Mac. This will open up another window. Use Control-Option-Right Arrow until you hear 'Version'. If you purchased it brand new from Apple within the last six month, more than likely you have Mavericks.

The 'Commands Help' Voiceover Menu. Control-Option-H-H. (hit H twice) is my best friend. It's a searchable VoiceOver Menu with most of the VoiceOver command. Example: You are looking for the 'Read Current Paragraph' keyboard command. Press Control-Option-H-H and then type Paragraph. It will then bring up all the commands with the word paragraph. I believe there are three.

No solution yet. One would think that Adobe would recognize that several complaints have been reported on this problem. Obviously, nobody knows how to fix it!! Sorry I can't be helpful!!

How do I get the iPad to read the camera connection plug in
Is the kit fully inserted, and which part of the kit are you using, the SD reader or the cable to camera ? If the SD reader, then how did the photos get on the card - if you copied them on from your computer then you need to create a DCIM directory off the root of the card, with the photos underneath it, and the photo filenames need to be exactly 8 characters long (no spaces) plus the file extension i.e. in a similar format as if a camera had created/written them.
If you are connecting direct to the camera then does your camera have a menu setting for 'Photo Transfer Protocol' (PTP) and/or Mass Storage Device ?
