How can i use an existing vpn connection without using the option "Send all traffic over vpn connection"?
I have been trying to get my computer (os x.7) to astablish a remote desktop connection to my work computer via a vpn tunnel. In fact I have just discovered that it works fine if i select to "send all traffic over vpn connection" from the options in the advanced setup of the vpn.
If the option is selected microsofts "Remote desktop connection for mac" works just fine. However without selecting the option it is not taking advantage of the tunnel but tries to connect as if the tunnel would not exist.
Now the question is how do I get program to use the vpn tunnel without checking the above option?
Thanks for any hints and pointers.
Then can her computer be authorized to both accounts?
Absolutely. You can authorize any given computer to up to five iTunes Store accounts.
If purchases are made on her account, to a computer authorized to my account, can I put those songs on my iPod?
If you connect your iPod to her computer, yes. Tracks download only to the computer from which they're purchased, regardless of which iTunes Store account is used for the purchase. Or you could copy the tracks from her computer to yours and then authorize your computer to her iTunes Store account. But that's sort of defeating the original purpose, it would seem to me.
is it better to buy music through Amazon downloads and/or actually purchasing CDs to avoid the security features iTunes puts on its music?
That's certainly an option. If it's an entire album I want, I buy CDs. That way I can import them at the quality I want and to whichever of my systems I want. Amazon or one of the other download stores that offer tracks as MP3 are also an option, though for me download stores are best when you just want a couple of tracks off a given CD.

I want to order a second copy of an existing iPhoto book. Though created in the smaller format now only the larger format is showing. How can I switch an existing iPhoto book back to the smaller format?
To change a book size duplicate it (select the book in the source pane and press command and D) since text flow and picture placements can change due to the size differences - then click on change themes, select the same theme and the new size
check it carefully
Before ordering your book preview it using this method - http://support.apple.com/kb/HT1040 - and save the resulting PDF for reference - the delivered book will match it.

HT1689 How can I play podcasts on my iphone without using data?
How can I play podcasts on my iphone without using data?
I used to sync my podcasts to my phone individually, but found out that the Podcast app works better for me. It continously downloads the podcasts (not really sure when, that's the only thing, when its downloading it may use data depending on where you are) and also deletes the ones i have listened to. Hopefully that will help you out!

Not true at all.
You only buy the right to your own personal use.
You do NOT have the right to distribute to others.
This is illegal. There is no doubt about it -
How can I add photos to a video without interrupting the sound of the original video?

Thanks for getting your details posted. Good job.
You further explained
I am simply wanting to “overlay” a new visual element without disturbing the underlying audio.
A classical way to do a Premiere Elements Overlay is to hold down the Ctrl key of the computer main keyboard and drag the new clip over the area of the one you want to replace on the Timeline. That should not do anything but replace one portion of the video on the Timeline. No change in duration video or audio track if you are dealing with video linked to audio.
If you hold down the Alt key of the computer main keyboard, I am envising a scenario where you want to add to (not replace) some Timeline content.
A just in case note, if you have video on Video 1 and 2 and the video in 2 does not have transparent areas in it, then all you will see is the Video 2 content. I believe that Hunt eluded to that concept as a possible technique for what you might be doing.
Another just in case, if you have not seen the following Adobe documentation on arranging clips, you might be interested in the following link
http://help.adobe.com/en_US/premiereelements/using/WS9B8F8208-EAE8-4b49-A79B-9479B46A8981. html

I bought an album on my iPhone and it never transferred to my iTunes account. It has disappeared now and I'm not allowed to buy it again. How can I find my missing music album or have the option to purchase it again?
Hello bubblegirl2,
Thank you for the details of the issue you are experiencing with your purchased album.
First, I recommend trying to download the album from you list of past purchases. Use the steps in the section titled "Download previous purchases on Mac or PC > iTunes Store" in the following article:
Download past purchases
http://support.apple.com/kb/ht2519
If you have tried those steps and still do not see the album, it may be that the album is hidden. Follow the steps below in iTunes on your computer to check if it is hidden and unhide it:
To unhide your purchases
Open iTunes on your Mac or PC.
If you're not already signed in, choose Store > Sign in.
Choose Store > View My Account. (You may be asked to enter your password again).
On your Account Information summary, scroll down to the "iTunes in the Cloud" section and click Manage.
Choose a content type by clicking Music, TV shows, Apps, or Books from the top.
Click the Unhide button next to the item you would like to restore.
Note: If the item you are unhiding is not already downloaded on your computer locally, it will begin downloading automatically.
iTunes Store: Hiding and unhiding purchases
http://support.apple.com/kb/ht4919
If you are still not able to download the album, you can report the issue with this purchases using the steps in this article:
How to report an issue with your iTunes Store, App Store, Mac App Store, or iBookstore purchase

How can I create a long employment form without making the form widget drag?
How can I create a long employment form without making the form widget drag?
Sorry Sachin, I mean that I created a simple form on the page from the widget and started adding fields to it. The more fields I add the slower the delay becomes in creating a new field. Even when I try to select and drag or move an item, there's a huge delay and sometimes the program feezes, loose what i've done and have ot restart.
I'm doing an enployment form that has more than 20 fields, at least, and I need to be able to build the fields in separate categories, like Education, Past Employment, etc... quickly without delay issues.
I can probably send you a snap shot of what I'm talking about if I cna post it or attach it here..?

How can I get a list of BSSIDs without using netsh?
I'm looking for an object that would have contents similar to the output of
netsh wlan show networks mode=bssid
I don't want to use unreliable parsing of text output, so using netsh is out. The WMI interface that worked in windows xp doesn't work now. There's an API, but there is no NET interface so it's pretty difficult to work with in powershell.
I know of a couple of adapters, but I'd like to keep this contained in one script. I don't think I could find or write a type for the API that I could invoke in powershell.
Is there anything else I'm missing?Oh, sorry, you have said that you don't want to use netsh.
I will involve someone familiar with this to further look at this issue. Hope there is a way for you to use without the usage of netsh.
There might be some time delay. Appreciate your patience.
Thank you for your understanding and support.

Thanks, but I think I got it all figured out. I used the C# code from the managed wifi api project (http://managedwifi.codeplex.com/) though it needed a little tweaking - had to get everything in one
namespace so powershell could easily consume it without external files. Had to do a little manual type conversion with the output because yay unmanaged and untyped API output. This still needs some tweaking to present it better, but this will do
the basics.
Note that this is two parts. String all the code from this post and the next into one ps1.

How can I keepalive for 2 different applications without using script?
Have a CSS with 2 web server loadbalanced. Initially the keepalive was set to ssl but now the client would like to add another keepalive type http. How can i do this without writing script. Though there is quite number of example in the forum but I'm still confused. Is there any clear and complete sample config for this type of installation.
Below is the example of working config of my client.
service server1
ip address 10.150.1.10
keepalive type ssl
active
service server2
ip address 10.150.1.11
keepalive type ssl
active
Owner Layer3
content Layer3_a
add service server1
add service server2
vip address 10.150.1.12
balance aca
advance-balance sticky-srcipIf you want to use multiple keepalives for a service, you must use a script. The alternative would be to create 2 content rules, and 2 sets of services, one for port 80 (or whatever) and one for port 443 (or whatever), and use http for one and ssl for the other.
