Two USB6008 on different hubs - how to tell one from the other
My PC supports two instruments where each instrument is made of a hub, an acquisition of data USB6008 and an another mfg DAQ. The two hubs connect to two USB ports respective on the PC.
I have code that traverses the tree of USB and concludes each hub and then searches each device in turn. This allows me to 'pair' two USB devices on a per-hub basis. Even though I have the USB tree info, I don't know the name of the device (e.g. Dev1) of just the info from the USB, so I'm not able to explicitly open the unit. Is it possible, I can open a device based on its USB hub/port location? It seems that all the open calls require the name of the device.
Thanks for all the ideas.
Mitch
Read the serial number of the data acquisition. You should then be able to find the name. Perhaps change the names of /dev1 to something more descriptive when you set in MAX.

When I look at a page of search engine results, I would like the colors of the results visited a much more different color than they are today. As v.s. blue black or blue v.s. yellow.
You are welcome
Disable the website of colors in the preferences (options) can have all kinds of side effects because it also disables background images and as such can cause buttons or links that consist exclusively of a background image to get invisible.
The NoSquint extension is much better in dealing with these issues.

How to keep separated from the other adjustment layers layers (PSE8)?
I would like some tips on how to keep to a standard layer adjustment layers to adjust the background (lower) layer.
Scenario:
I created a solid background layer as a backdrop to the image of a small sculpture. The bottom layer is a layer of just the image of the sculpture. Above the layer of the image of the sculpture are a number of adjustment layers that are supposed to apply to the sculpture only layer. I would like to know how to store the adjustment layers above to adjust the background layer (lower).
Thank you
Highlight each adjustment layer in the palette layers (Ctrl + click)
Press Ctrl + G
The miniature icons should move slightly to the right with an arrow indicating the saturation for the sculpture below layer downwards.

my mother has two computers that are running windows 7 and she wants to give me one of them, but it first wants to transfer or share all his stuff from one to the other. We network cables and such can I connect the on computers and share information from one to the other?
Hello
To connect two computers with a cable, not a router, it must be a crossover cable.
These are special cables, but they are not expensive.(You can configure a network or a host group (see below))

I can't have multiple files open at the same time! I need to compare the content from one to the other. How to display two files at the same time?
Hi sindres79946597,
Open Acrobat Reader DC, navigate to the Edit-> Preferences-> General-> uncheck "Open Documents in the new tab in the same window.
Now, reboot your system, when you open multiple PDFs that all will open in a new window so that you can easily compare.
Kind regards

In Labview, is it possible to put two windows (both sides) appears on the same screen together, one behind the other, during run mode?
It's a shame
Secondary, it's a great way to call subVIs and you load only code when you call it, so it ease your use of resources.
Anyway, you can call Vi as pop up:

You could split your FP using the separator.

Or you can use the control tab.

Change the system drive
I'll try to explain my situation better than I can.
My situation is that when I used to have XP installed, I had installed the only drive I had back then which is now the drive D, for a long time, so I have Windows Vista Home Premium 32-bit, Windows 7 Home Premium 32 bit installed on two different discs, Vista is installed on drive C and 7 is installed on drive E , but I don't have XP that I had managed to get rid of it.
My problem is that the drive on which Windows XP to reside has always left this disc marked as system in the disk management window, and I was wondering how to do that one of the other readers who has Vista or 7 that the new system?
I already managed to change the startup disk from drive where Vista is installed to, it's just that I need to change the disk that is marked as system to another drive, such as D drive begins to show signs that it comes at the end of his life and I would like to move the startup folder as well as the other files needed to start on the other.
I assume that you installed Windows XP 1, then Vista, 7 (these 2 OS not in order)?
And Vista and 7 was by all means upgrade installation?
Since originally, that you have installed Windows XP on drive D, it should be marked as 'system' and retains so the tag 'system '.
The volume of the 'system' should be identified as the first primary partition active. It may or may not have the files it contains.
The fact that the system considers "system drive" does not mean that there are files that it contains.
Now, you want to delete the existing volume and create a new volume. Needs to be done outside the facility.
When you start the cd or DVD to start the installation list us readers, if you remove the volume the volume drive letter is already booked, so you get the next available drive letter, do not re-use the deleted volume drive letter.If he removed during installation and then recreated as a new volume (formatting does not remove the volume, you need to delete the volume and recreate it)

Try to format the XP partition and change the drive letter.

I have seen the user that one of my menu apps start how do I see on the other?
I installed Microsoft office on my pc but I got 2 users. I have seen the user that one of my menu apps start how do I see on the other?
Former title: need help please
Soumya, salvation
Thanks for posting the query on Microsoft Community.
If I understand correctly, you want to access the applications in the two accounts on your system.
When you say "I could see menu start of the user as a single of my apps", are you talking about office applications or other applications?
For the office, if you are installing Office into the administrator account, it will be copied to all user accounts on its own.
For other applications, you can consult the links below and check if it helps.
I hope this helps to solve the issue. If the problem persists, get back to us. We will be happy to help you.

How can I boot from the Windows 7 Installation CD so that I can reformat the hard drive before reinstalling Windows 7? I have already reinstalled Windows 7 from the CD, but that has not solved my problems. When I put the factory CD in my CD player, it won't always boot from the CD. When I put my Windows 7 Ultimate CD in the CD drive, it doesn't always start from the CD. I realize that the reformatting is not always necessary, but I caught a few viruses (despite anti-virus running) and I need to start with a clean hard drive.

You must go into the BIOS and change the boot on CD order
first push.How to get into your BIOS? It is not dependent on Windows, but on what he
motherboard/BIOS card that you have. In fact, you need access to the
BIOS before Windows begins to start. A common method is to press
the key delete when you turn on first, but this is not necessarily true
for your computer. Watch the display carefully when you start first;
There is often a message here to tell you what to do. If this is not the case, check
your system documentation or check with your provider.
