Gets an object to display unique pair of values.

I have the following requirement:

There are two attributes in my viewobject, Attribute1 and attribut2.

Based on the combination of these 2 attributes, I fill a transient VO.

Two of these attributes may have duplicate values, but I need to display only these attributes unique combinations.

Please suggest an approach for this.

Hello

You could do something like (attribut1 + Attribute2) .hashCode)

Qosmio G20 - could not get the video to display on the LCD screen

I have a laptop Toshiba Qosmio G20, running Windows XP MCE.

The DVD player on board isn't sounds very well so I thought I would plug an external DVD drive to expand its use. After a lot of internet research, I finally found how to do this. Here's my setup.

Using the monitor port I used the adapter 3 RCA jacks. (There is no S-video on the DVD drive and an adapter did not work). I finally discovered that in order to get the image on the screen, I have to use Fn + 4. Now, here's where I'm having the problem. I can't get the video to display on my external LCD. FN + 5 didn't do. The monitor is an I - inc AH191D and is connected by VGA cable. There is no driver other than the one for the VISTA operating system... That is why it is not anywhere in the Device Manager.
Here are the settings I use in order to have all that shows on my desk, shows on the monitor.

In Control Panel open to the screen. Properties
Number chosen 1 - multiple monitors GeForce Go6600 video card...
Advanced under
the GeForce G06600 tab,
nViewDisplay Mode: clone 1 a 1 b
The main screen: digital flat screen
Secondary display: AH191

I also tried using the properties of controls on Toshiba. He says under TV output TV output but gives options of the program, but I don't know what I would use. Any ideas out there?

Wait I'm confused, if you try to send the output of your external DVD drive in the laptop, and then display the image on an external monitor attached to laptop?

If you use the DVD player on your laptop, it will be good quality S-video as a signal of low resolution.

Is there something wrong with the DVD player?

If it's just the DVD software you don't like, you can download other DVD players. PowerDVD is excellent, its better than WinDVD and other players in my opinion.

How to get the icons to display correctly in the Finder?

At the time of the "classic" Mac OS, if the icons are not correctly display in the Finder, we could 'rebuild the desktop file' to correct the problem. I've recently updated to Yosemite, and most things work well, but for some reason, most of the files in the Finder .webloc now show as blank icons (but not all; a few show the correct icon). There is no model, I can see: some very old .webloc files now show a white icon (where I know that their icons used to be correct), while the most recent show the icon of correct - although I just created four (by dragging the URL of the Safari, the usual method) which are all empty. Sometimes they appear with the older icon, with the symbol @ (although those who seem to have changed vacuum after running and restart maintenance). I tried from an external disk, repair permissions and repair the file system, as well as cleaning with the utility of Maintenance (which clears the web browser and other caches), nothing works. Does anyone know how to get the computer to display these icons correctly?

May be a corrupt .plist.

Make a backup, preferably 2 backups on 2 separate drives.

Go to Finder and select your user folder. With this Finder window as the windshield, select Finder/display/display options for presenting or order - J. When the display options opens, check "show the library folder. This should make your visible user library folder in your user folder. Select the library. Then go to Preferences/com.apple.finder.plist and com.apple.desktop.plist. Move the .plists on your desktop.

Relaunch the Finder by restarting the computer and test. If it works fine, delete the plists from the desktop.

If the same, return the .plists to where you obtained since, by crushing the latest.
