Language choice for library to be linked in both KMDF and UMDF drivers
Hello,
I'm writing a library that needs to be linked into both KMDF and UMDF drivers and was wondering if i can use C++ to write the library. C++ in UMDF should work fine, but going over lot of discussions about using C++ in KMDF drivers,
it looks like very basic C++ should work fine but using virtual functions, new/delete etc will probably come back and bite you in many ways. Most of these discussions are from way back in 2009 or earlier.
Do those still hold true ? What is the extent of C++ i can use in a library that will be linked into both UMDF and KMDF drivers ?
Thanks

If you are using the Win8 WDK or later, you should be able to use a very limited C++ and the tools will flag constructs that are not supported. The discussions you found are mostly still valid, there is no new and delete (unless you roll your
own), but you can use simple classes and C++ syntax. Basically take a look at the old forum post

Language choice for Guest Users
How to the remember language choice for Guest Users? You cannot save perferences in Guest user, but the default language is not desired.

I have only 2 choices for contact groups on the iPhone 5, hotmail and iCloud. If I click both then I have all my hotmail contacts which I don't want. However if I only click iCloud, any new contacts I add don't show up
Only contacts added to the iCloud group will sync with iCloud. To make this your default, go to Settings>Mail,Contacts,Calendars...scroll down to the Contacts section and tap Default Account. Here, choose iCloud as your default. After doing so, new contacts will be added to iCloud and sync with your iCloud account.

Multi language Support for Library project
Hi All,
I am using Library for my project.I want to support multilanguage for the libraries also.
Please help me to solve this issue.Thanks in advance.Hoan - is your question what are the considerations when creating multiligual catalogs? If so, I can tell you that at other clients I have seen them use a single catalog for one or two languages. For the two langugages, such as Spanish/English, you can create a single catalog with both of them. Once you get to more than two languages, the catalog would get unweildy and is therefore not suggested.

Regardless of where I right-click on a displayed webpage (NOT the menu bar at the top of the screen), be it highlighted text, a blank spot in a webpage, or anything, the context menu for a hyperlink pops up (with the options for opening it in a new tab, window or private window, bookmarking), and none of the options actually do anything even if it is a hyperlink I'm clicking on. Using keyboard shortcuts like Ctrl + clicking work fine. I haven't installed any plugins recently, and it only started a few hours ago. Wat do?
Try disabling Firebug and see how it is.

Migrate iTunes library to Mac mini with both SSD and HHD
I have been using a Mac Mini for my media center for a while and just got a new one with the two drive option. It has a 256GB SSD (where the OS is stored) and a 750GB HHD. My iTunes library is about 400GB. When I try to use migration assistant to transfer the media, it won't let me because the default location for the iTunes library is on the SSD, which isn't big enough. I have tried manually moving the media folder to the new computer and then telling iTunes where the library is, but iTunes shows no music. Please help!
Copy the enttire /Music/iTunes/ folder to the HD on the new computer.
Hold Option and launch iTunes.
Select Choose library and select the iTunes folder on the HD. -

Attatched is an image of the requested result. I'm new to Dw so this might be an easy bit of code, but with research I haven't been able to find an answer.
Ideally, the numbers in the middle are links (centered on the page); and the text is a description of the link which floats to either side of the links, but is not necessarily centered; nor linked.
I would really appreciate the help of someone more knowledgeable. Thanks in advance.
The code I'm working on follows the image.

Perhaps this updated code will help clarify. I want the links to be centered on the page. But the link descriptions to float to either side? Does that make sense?

You can try to '''Enable''' the '''Extension''' in '''Tools''' ('''Alt''' + '''T''') > '''Add-ons''', or right-click on it and '''Find Updates'''.

Laptop not recovering sleep- Nor any choice for LID
For many years i have been forced to reset my laptop when completed with my session. There is no choice for sleep when lid close in power options and sleep mode works randomly if i go through my windows button. Here are examples of what happens:
If i leave the laptop for too long the laptop fan continues and the Network light turns amber/orange color. When that happens if i even tap the power button the laptop immediately shuts down( no need to hold it). If i put it in sleep mode, through the windows button, it goes for a while and the similar thing happens. There seems to be no rime or reason when the sleep mode works. There was a time when Internet Explorer was open it wouldn't work, so i stoped using it.
I believe the sleep issue has to do with a process continuing and not allowing the computer to sleep.
I use to have a lid option in my power menu, but for some reason that is gone(even in the advanced options). I have updated the bios, changed the drivers and laptop has done the same thing since we bought it.Hi @Dputzjr
Welcome to the HP Forums!
It is a fantastic place to find answers and information!
For you to have the best experience in the HP forum I would like to direct your attention to the HP Forums Guide Learn How to Post and More
I understand that you are not see any option for sleep under the power options.
When you leave the laptop for too long the laptop fan continues and the Network light turns amber/orange color. Once this happens if you tap a button the computer shuts down. If you use the Windows button to activate sleep mode it works for awhile but then the same thing will happen.
You believe there is a process that is not allowing it to enter sleep mode.
Here is link to Troubleshooting Sleep and Hibernate issues (Windows Vista) that may help.
Another thing you can try is this step.
Go to the command prompt and right click and run as administrator.
Type powercfg -restoredefaultschemes and press enter.
This will reset the power schemes.
If you still think it is a process causing the issue. you can try using msconfig to determine the offending process.
HP Notebook PCs - Using Windows Vista System Configuration Utility (Msconfig)
If the issue should still remain you can do a restore back to when it was working.
HP and Compaq Desktop PCs - Using Microsoft System Restore (Windows Vista)
If that does not work or is not an option, I suggest you do a recovery back to factory.

Hungarian language pack for E71
Hello i need Hungarian language pack for E71 . how can i got it and how can i instal? thx for help .
As an end-user, you cannot.
You have to take the phone to your nearest Nokia Care Point and ask them to install a Hungarian/Magyar language pack.
Since the absence of a language is not a fault in the phone as such, this is not covered by the warranty and there may be a small charge for the service. Also note that language packs don't survive resets or firmware updates on most phones, so if you do reset yours or update its firmware at a later date, you will probably lose the language pack and have to have it re-installed.

The context of the questions is admin/config etc. screens for Weblogic supported in how many and which languages besides English.
ThanksYes, iWork comes with both English and Japanese localizations and should switch automatically to Japanese if your wife's OS X account has the system language set to Japanese. You can probably also have it run in Japanese without the system being that way by unchecking English in the Languages tab of Get Info for the program you are using. One copy is fine.

Links between some pages and pdf's not working: muse
I have two sites with the same muse business catalyst name for preview. How do I create different names? Is it necessary to preview site?
I am have a lot of pages that no longer link on both sites and I cannot get pdf's to link. Please help?
erin pashelinskyHi Erin
I believe you have published same Muse file with 2 sites on Business Catalyst , you can update the same sites with the modifications you made in Muse.
In publish window , click on options and select the same site from drop down , publish the site and old pages will be replaced with new content that you have added in Muse.
Thanks,
