[RDE] How do you control menuitem enabling/visibility when extending RDE?

I'm beginning the process of writing additional plug-ins for RDE, and I'm trying to figure/find out how I can control how menuitems are enabled, or even prevent them from showing, dynamically (as I would in Eclipse, for instance). Right now, it seems like once you register an editor as being capable of editing a given file extension it always shows up in the context menu, but I'd like to be able to control that based on various settings and/or based on the content of that file. Is there an existing mechanism for doing so? If not, could you point me at the code I would need to modify in order to add such a mechanism?

If it's slow on startup it would be extensions loading or LaunchDaemons starting up.
You should have a look in:
/Library/LaunchDaemons
/Library/Extensions
You can count out anything in your home folder and it shouldn't put anything in /System as that's reserved for Apple.

How do you control the volume to the earphones?

How do you control the volume to the earphones?

Apple Support Communities updatesActually I knew that part of it, but I had to go to Settings to correct something. They are working now that I fixed something that I have no recollection that I altered in the first place, nor do I now know what in heaven’s name I fixed this time. All I know is that I must have gone to setting a million and one times and the last time was the one I did something right.
Thank you for your help however.

                                With the volume up and down keys unless you purchase a set with a volume control connected to the chord.

How do you control number of cycles shown on chart

How do you control number of cycles shown on chart? I've selected a sweep chart and I'm not seeing the vertical bar on the chart when the program runs. This is probably because I'm not seeing a full cycle of the periodic signal I'm trying to display. I need to set the chart to display multiple cycles. Any help will be greatly appreciated.
Solved!
Go to Solution.

Right click the chart and set the desired number of points in the history buffer (right-click...chart history lenght...). Then set the x-axis not to autoscale and to cover your full history range.

How do you make invisible folders visible

how do you make invisible folders visible? My hard drive icon will not show up? I did not set-up this computer.

The instructions I provided have nothing to do with Time Machine. Did you try what I suggested? If you select the "alias" file then CTRL- or RIGHT-click and select Show Original in the context menu.
Maybe it would be helpful if you were to provide a more complete description of this issue.

My question was how do you control bass and treble on your Mac pro? he act of the matter is you can't. Why don't they just say that rather than reading all of the ********

My question was how do you control bass and treble n a Mac Pro with the latest software.
The answer is you can't
In summary why don't you say that upfront?
Instead of reading a bunch of crap that says nothing

just a suggestion: try soundflower or Audio Hijack Pro. I know with the 2nd one, you can control the bass, treble, and all that, with anything that makes sound, from itunes, to Safari, DVD player, Skype ( I guess) and other stuff. Worth the $, IMO, so in answer to your question dbumgardner1, no, no you can't. I suppose in that sense, Windows has us at a loss. We also need 2nd party stuff to play BluRay's, too. However, I haven't seen any Macintosh viruses (virii?) for a long long time....
so, there's that....

HT201335 can you control video from computer when you airplay

I just added Appletv and connected my Computer and TV. I now see my TV but how do you control your computer from your tv or maybe you don't the remote does not do anything pertaining to the computer i see on the TV

You control the computer the same as you would normally. The image is simply being mirrored to the Apple TV, you cannot control it from there using airplay.
If that is what you are looking for then you need to search for a VNC client.

How can I control the image size when I export form iphoto, the choice is too limited, I need to send a photo under 3 MB but if I choose high quaulity it is only 1.1 and i need to keep the best quaulity I can. Thanks for help.

How can I control the image size when I export form iphoto, the choice is too limited, I need to send a photo under 3 MB but if I choose high quaulity it is only 1.1 and i need to keep the best quaulity I can. Thanks for help.

Any image can only be as large as the Original. With a program like Photoshop you can UpRes an image and get it to a bigger size, larger files size as well, but the actual quality of the image will be degraded, depending on the UpRes system and the original quality of the image.
iPhoto is not the program to be doing that in and I don't think it even has that option.
So I suspect the image you are trying to send isn't much bigger than what you are getting. You can also try Exporting it from iPhoto to yopur desktop and see what size you end up with. If it is still that 209KB +/- file size then that is the size of the original image.

How do you update the Bios safely when using onboard RAID mirror? Z87-G45

How do you update the Bios safely when using onboard RAID with Z87-G45? I'm using a simple two drive, RAID 1 mirror setup.
I'm currently at bios 1.4, and want to move up. However, last time I upgraded the BIOS, the machine rebooted with improper settings for the RAID (they get hosed during BIOS flash) and Windows decided to auto-repair the only boot drive it could see, one half of the mirror, because it couldn't see the RAID array correctly and *POOF* bare-metal reinstall required.
My PC will not let me press the DEL key on bootup to access the bios, even with MSI Fast Boot not installed. It just ignores the DEL key and tries to load windows which, if that happens, will flame-out my RAID array after a bios flash if I can't catch it to enable the RAID first before windows loads.
I do not want to rebuild my PC again simply because I do a BIOS update.

FYI: BIOS 1.4 & 1.8 are using the same RAID version: 12.7.0.1936
based on this RAID surprise should not hapends.
But as pandaz says if you have no issues, leave bios update alone.
there are still risks something to messed up,
best do a backup of your data just in case if you want to try latest version

How do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it when you just play a slideshow.

how do you shuffle the image order when creating a new slideshow in apterture 3? i would like to do this automatically when creating a new slideshow. i see how you do it with presets when you just play a slideshow, but i don't see an option to randomly shuffle the slide order when you create a new slideshow. i know you can sort it by different fields, but i want it to be random. thanks.

If you want to rearrange images in random order you can try an AppleScript:
retrieve a list of selected images from Aperture
shuffe the list properly
create an album in Aperture and add the images from the list to the album (make sure that the album set to be orederd manually)
Here is a sample script that shuffles the selected images and displays them in random order in Full Screen Mode:
on removeItem(ims, i)
-- remove the item at position "i" from a list ims
          if ims is {} then return {}
          if (length of ims is 1) then return {}
          if i < 2 then return rest of ims
          if (i = length of ims) then return (items 1 thru (i - 1) of ims)
          if i > (length of ims) then return ims -- should be error?
          return (items 1 thru (i - 1) of ims) & (items (i + 1) thru (length of ims) of ims)
end removeItem
on shuffle_items(ims)
-- shuffle the items of the list "ims" randomly
          local numitems, ims_shuffled, nextrest, nextpick, i
          set numitems to length of ims
          if length of ims < 2 then return ims
          set ims_shuffled to {}
          set nextrest to ims
          repeat until nextrest is {}
                    set i to (random number (numitems - 1)) + 1
                    set nextpick to item i of nextrest
                    set beginning of ims_shuffled to nextpick
                    set numitems to numitems - 1
                    set nextrest to removeItem(nextrest, i)
          end repeat
          return ims_shuffled
end shuffle_items
on shuffleIms()
-- retrieve the selected images from Aperture
-- and display them in random order in full screen mode
          local imageSel, shuffled, i
          tell application "Aperture"
activate
                    set imageSel to (get selection)
                    set shuffled to my shuffle_items(imageSel)
                    set fullscreen to true
                    if imageSel is {} then error "Please select some images."
                    repeat with i from 1 to count of shuffled
                              reveal {item i of shuffled}
delay 3 -- chnage that to the time you want
                    end repeat
                    set fullscreen to false
                    return shuffled
          end tell
end shuffleIms
shuffleIms()
Some more code snippets to go from here:
To create an album:
                    tell library 1
                              if not (exists album "shuffledAlbum") then
make new album with properties {name:"shuffledAlbum", image version:shuffled}
                              end if
                    end tell
And to add the images from the shuffled list to the album:
                    repeat with i from 1 to count of shuffled
                              duplicate item i of shuffled to album "shuffledAlbum"
                    end repeat

HT1414 How do you recover your security code when purchasing extra moves on games

How do you recover your security code when purchasing extra moves on a game?

Do you mean the passcode for Settings > General > Restrictions so that you can turn in-app purchases back 'on', or something else ?
If the Restrictions code then was it on the iPad when you last backed up ? If not then you can restore to that backup and it should be removed. If it was on the iPad when you last backed up then the only way to remove it is to reset the iPad back to factory defaults and you can then re-sync your content back to the iPad - you won't be able to restore to the backup as that will keep the code in place.
If you mean a different code ... ?
