Can you have the mini dvi, or any output video source, on all time?

I work for a University in a department that supports classroom technology and other various A/V type things. We recently set up a "collaborative cluster" computer lab. On each table there is 5 iMac's that can be used to work on project or class assignment independently, but there is also a LCD mounted on the wall at the each table so that at the press of a button that particular iMac's image can be displayed for the group to see. My question is, is there a way to always keep the mini dvi port on, because once you switch to another iMac or the teachers station it doesn't recognize that a second display is there anymore. If there is such a thing, would it also stay there after a restart.

First verify that the problem is in the display's cable, not the computer's Mini DisplayPort. Can you try a different display with your computer, or a different computer with your display? If not, try holding the plug firmly in the computer while wiggling the cable near the plug. If that doesn't cause problems, but moving the plug does, then the problem may be the port on the computer.
If it is the display's cable, it can be replaced, but it does require some work

Recently I bought a mini DVI to HDMI converter from eBay for my iMac 21.5 Mid 2011, but only later I realised that it does not have the mini DVI port in that. How can I connect my iMac to a LG smart TV through a HDMI cable?

This is the picture of all the ports from my iMac
This is the mini DVI to HDMI converter which I bought from ebay. And I have the HDMI cable to connect it to my TV
Could anyone please suggest me a solution how I could connect my iMac to the LG smart TV? Also I need to know if this transmits the audio as well to the smart TV?
Suggestions are welcomed. I really appreciate and thank you for your time

I would suggest looking into a Thunderbolt to HDMI connector. In this case, you may be able to use the TV as an external monitor. For this option, please confirm through additional research. I have not tested it personally.
You can also use an Apple TV, which connects with HDMI. In this case, you can use Airplay Mirroring. Not all Macs support Airplay Mirroring, so you need to check first. I have a Mid-2011 27" iMac, and it supports Airplay Mirroring. I don't use it often because my TV is in another room, but I just tried it and it worked. It had to change the screen resolution to work well, so I don't know if I would want to use it as my day to day monitor. http://support.apple.com/kb/ht5404

Can you have the PDF file do calculations in a fillable Acrobat PDF?

I want to create a hot lunch form for our school. I want to be able to have the user fill in the QUANTITY, but have the form automatically multiply the quantity by the cost to and give the total amount due. Is this possible? Should I create the form in Excel, and then convert it into Acrobat?

Hi there, yea thats easily possible. and lots of ways to do it.
The easist way i think is as follows
1. create a field thats contains the cost of the lunch and hide it if necassary then in the total cost box;
2. double click the field with the select object tool and go to the calcualte tab (far right);
3. click the button next to 'value is the' and change sum to product; and then
4. click the 'pick' button and choose the fields (ie quantity and price) you want to multiply and whola!
another way (and neater) is
1. Choose the 'Field' that will have the total cost in, go to the 'calculate' tab and choose 'simplified field notation' (this only works if your field doesnt contain space or special charactes)
2. click 'edit' on the right
3. type for example; quantity * 2.75
Quantity is name of field * = times and 2.75 is the price etc.
4. close dialogue box and whola :-)
Hope that helps?

How can you have the app tabs positioned to the right of the FireFox button when maximized?

App tabs are '''normally''' positioned to the right of the FireFox button. However, when you shrink the window and then maximize again the app tabs appear below the FireFox button.
Anytime an app tab is open and you maximize, adjust window, maximize, the entire tab bar is bumped down under the FireFox button. Having just regular tabs open does not have this problem as they correctly position themselves to the right of the FireFox button when maximized.

Zero is in the middle where it says "none".

Do you have the 'By Artist' bug on iPod Video 5G??

Can anyone help me confirm these?
The first one is so annoying, as it is effectively disabling a large number of my songs when I go to look for them by 'artist'. The second bug is just annoying!
1. iPod 5G artist listing bug
Environment:
Bug occurs when an 'Artist' has songs attributed to only 1 album and you have tracks for that artist that are not associated to any album (album ID3 tag is blank on some tracks).
Problem:
When you browse to Artist, and select the artist, it jumps straight to the album listing of the 1 album you have, not allowing you to browse 'All' to see songs that are not connected to any album. The songs are definitely on the iPod though, as they are listed in the 'Songs' area. Desired behavior is for 'All' to list all tracks, both on albums and not.
Supplemental: This needs to be fixed regardless - 'All' needs to be present on the screen if the artist only has 1 album but tracks not associated to that album - however, what may be a good addition is a menu option for browsing songs that have no album. - so you could go 'All' (and potentially be faced with a very long list of songs) or choose 'No album' (or similar) to show songs by that artist that have no defined album. I can see user behaviour in some tasks needing this option.
2. Artist 'All' view song order bug
Environment:
When you have an artist that has many albums of content, all with songs.
Problem:
Go to an artist you have lots of albums for, then choose 'All' instead of an album. The tracks are ordered alpha *by album* (with the album details not shown, just the song names, obviously). The songs are not listed by 'alpha song title' as you would expect them to be. How on earth are you supposed to find anything on this list? This has to be a bug. Expected behaviour should be that if a user browses to an album, a user wants to see the tracks ordered by track listing, and if no track listing ID3 info, by alpha instead. However, when I go to 'All', I'd expect an alpha ordering by song title (unless shuffle was on, of course!). If you have one unit of information - song titles - ordered by another unit of information that isn't present or explained, then users consider the ordering to be 'random' instead. Please fix!

Apple's response on your first issue:
http://docs.info.apple.com/article.html?artnum=302773
I agree that the second issue is kinda annoying (alphabetic listing of all songs when browsing through Artists -> [artist name] -> All)

Can you have the same song on 2 different albums ?

I would like to use the same track on 2 different albums.
For example, one track on the original album and the same track on my own compilation album.
One way would be to make two copies of the track and call them different names.
e.g. UseSomebody1.mp3 and UseSomebody2.mp3, then these two tracks can be added to the library.
But this seems a waste of space.
I have an existing compilation album with odds and sods of my own tracks. But I want to pick and choose a few tracks from other albums and add to my existing compilation album.
I know about playlists but this isnt the ideal solution either, because I have an existing compilation album already and I want the album to be in the main library (i.e. not have to go thru the playlist menu on the iPod).
I just wondered if there was a way of having 2 seperate tracks in iTunes that point to the same file.

I made a copy of an mp3 file on an existing album and tried to add it as a new file, but it doesnt appear....
I made a copy of this mp3 file on my desktop and called it "Kids_MGMT.mp3"
I added the file to library but the second copy does not appear, even after a refresh and a search.
Find the original library entry and change something in the metadata, e.g. add an Album Artist even if you don't need it. Then go back to the renamed copy and move it into your iTunes folder at an appropriate location, right-click the file, and choose Open With > iTunes. It will immediately show as a separate library entry.

Can you have the same smart object in two files?

The situation:
I have a 'base' file A, with two (different) smart objects B and C. Now I want B and C to both contain a third smart object D, and I can't get that to work.
I can place the same file as a smart object in B and C, but it becomes two different smart objects, which are seperately editable. I would like to be able to edit smart object D and the changes to be visible in both B and C and in turn in A.
Is this at all possible?
and please, I'm not looking for workarounds. I have plenty of those, but it would save me a lot of time time if this were possible.
thanks

How can you have the "chat" or "message" site on Facebook show both your end of the conversation , and the other persons as well without going back to "message to hear the other parties response?

Does anyone know how to have both your message and the person you are messaging show up on Facebook as it does in chat. Chat does not work on my iPad as it does on the computer. I use "messages". But have to keep going back to messages to here the reply.

It is my blog... maybe you'll find more info there. I'm a big fan of shapes in all their forms, and of advanced/shared actions.

How can you control the export types from DHTML output?

I am currently using the JRC from CR4E V1 patch 7.
When I generate a report as DHTML and use the export button I am presented with 5 export options:
Crystal Reports
Adobe Acrobat
Microsoft Word - Editable
Rich Text Format
Comma Separated Values
I would like to control which of the 5 options are presented to the user. I was looking in the crystalreportviewers115 folder for some JavaScript that could be edited. I found export.js which appeared to have code that was creating the choices for a dropdown (getFormatDropdownList()), however this code did not get executed when I ran the export.
Any help would be appreciated.
Thanks,
Richard

Yes - the JavaScript that's in export.js was rolled into inline code in the Java jar files sometime during version 11.5.
It's no longer customizable.
An option is to use HTTP Filter on your Java Web App to modify the outgoing JavaScript instream, but that's never a pretty solution.
Sincerely,
Ted Ueda

IMac G5 (no iSight) TV-OUT stuck, even after unplugging the mini DVI adapto

Hello.
I have an iMac G5 (2.0Ghz, no iSight) for some time now and everything has worked great. I also have the mini DVI adaptor, which connects the iMac to an analog TV. This connection has also worked fine over the course of about a year now. Last night, after watching a movie on the TV through the iMac, I unplugged the adaptor, expecting the iMac to detect the unplugging, and revert to the original resolution, however that has no worked. After selecting "Detect Displays" from the menu, nothing happened. Restarting also hasn't worked. When I tried to plug in the adaptor back, the output to the TV also worked great, but unplugging changed nothing.
I tried to fix permissions on the drive, and though there had been permissions to be fixed, after doing so, nothing changed.
I tried booting from the installation CD, that also didn't work.
I tried booting from my iPod, on which another operating system is installed, that also didn't work.
I also read on the internet, here:
