My thunderbolt gigabit ethernet adaptor does not work on hotel ethernet connections, My thunderbolt gigabit ethernet adaptor does not work on hotel ethernet connections
I recently purchased a thunderbolt ethernet adaptor and I realised that when I am out of town (I travel alot) the adpator does not work with the hotel etherenet network regardless of whatever hotel I am staying at. Does anybody else have this issue? is there a software or update I need to download? help!
maybe it just takes a lot longer to acquire an IP address at the hotels vs your home, where the network is already known
next time, connect it and then open network under system preferences, you'll be able to see the adapter's progress in acquiring an IP address

I have a new airbook, 10.7.4 LION, thunderbolt ethernet adapter and when trying to install 1.2.1 thunderbolt upgrade it says "this software not supported on this system"? Any advice on how to get the adapter to work?
Welcome to Apple Support Communities
If you purchased the computer before 2010, your computer hasn't got Thunderbolt, so you can't use it -
The question is not so clear i will try to explain here.
I have a trackBar scroll event:
private void trackBar1_Scroll(object sender, EventArgs e)
LoadPictureAt(trackBar1.Value, sender);
ConvertedBmp = ConvertTo24(trackBar1FileInfo[trackBar1.Value].FullName);
ConvertedBmp.Save(ConvertedBmpDir + "\\ConvertedBmp.bmp");
mymem = ToStream(ConvertedBmp, ImageFormat.Bmp);
backTexture = TextureLoader.FromStream(D3Ddev, mymem);
scannedCloudsTexture = new Texture(D3Ddev, 512, 512, 1, Usage.Dynamic, Format.A8R8G8B8, Pool.Default);
timer1.Stop();
Button1Code();
timer1.Start();
b1 = ConvertedBmp;
b1.Save(ConvertedBmpDir + "\\b1.bmp");
trackBar2.Enabled = false;
if (!this.backgroundWorker1.IsBusy)
label2.Text = "מעבד נתונים";
this.backgroundWorker1.RunWorkerAsync();
else
this.backgroundWorker1.CancelAsync();
First LoadPictureAt method:
private bool LoadPictureAt(int nIndex, object c)
bool bRet = false;
if (nIndex >= 0 && nIndex < trackBar1FileInfo.Length)
if (c.Equals(trackBar1))
pictureBox1.Load(trackBar1FileInfo[nIndex].FullName);
bRet = true;
if (bitmaps != null)
if (nIndex >= 0 && nIndex < bitmaps.Length)
if (c.Equals(trackBar2))
pictureBox1.Image = bitmaps[nIndex];
bRet = true;
return bRet;
Then the ConvertTo24 method:
private Bitmap ConvertTo24(string inputFileName)
sw = Stopwatch.StartNew();
Bitmap bmpIn = (Bitmap)Bitmap.FromFile(inputFileName);
Bitmap converted = new Bitmap(bmpIn.Width, bmpIn.Height, PixelFormat.Format24bppRgb);
using (Graphics g = Graphics.FromImage(converted))
// Prevent DPI conversion
g.PageUnit = GraphicsUnit.Pixel;
// Draw the image
g.DrawImageUnscaled(bmpIn, 0, 0);
//converted.Save(outputFileName, ImageFormat.Bmp);
sw.Stop();
return converted;
Then ToStream method:
public static Stream ToStream(Image image, ImageFormat formaw)
var stream = new System.IO.MemoryStream();
image.Save(stream, formaw);
stream.Position = 0;
return stream;
What it does is taking a Bitmap image and make a doppler radar effect on it and detect color only places that there are pixels(clouds) in it.
Here is a screenshot:
You can see the doppler shape and it's moving around and highlight the places with clouds.
So when i move the trackBar1 to the left each time on another Bitmap image it's showing the doppler effect and the clouds.
The problem is with the trackBar2 scroll event:
First when i'm running my program and enteric to this new form that scan the clouds and show the doppler radar effect a backgroundworker1 is working:
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
BackgroundWorker bgw = (BackgroundWorker)sender;
if (bgw.CancellationPending == true)
return;
else
while (true)
bitmaps = ImagesComparison.get_images_with_clouds(b1);
for (int i = 0; i < bitmaps.Length; i++)
bitmaps[i] = ConvertTo1or8Bit.ColorToGrayscale(bitmaps[i]);
break;
What it does is getting into bitmaps(Bitmap[]) 15 new bitmaps from one given bitmap. The given bitmap is b1.
b1 i'm using it in trackBar1 scroll event.
All the new Bitmaps in bitmaps variable array are Format32bppArgb.
While i checked on my hard disk the images(GIF type) i'm using with trackBar1 are all Bit Depth 8.
The images i'm using with trackBar1 scroll event are GIF types and Bit Depth 8 on the properties.
The images i'm using in trackBar2 are Bitmaps and they are Format32bppArgb.
So first thing i thought to convert all the 15 Bitmaps in bitmaps to 8bit:
for (int i = 0; i < bitmaps.Length; i++)
bitmaps[i] = ConvertTo1or8Bit.ColorToGrayscale(bitmaps[i]);
But it didn't work it's just turning them to black gray scale colors not what i was thinking about.
In the backgroundworker completed event i'm converting the bitmaps to 24 like i'm doing with the Gifs in trackBar1 scroll event:
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
trackBar2.Enabled = true;
trackBar2.Maximum = bitmaps.Length -1;
bitmaps[0].Save(ConvertedBmpDir + "\\bitmapsfirstimage.bmp");
for (int i = 0; i < bitmaps.Length; i++)
ConvertedBitmaps.Add(ConvertTo24(bitmaps[i]));
ConvertedBitmaps[0].Save(ConvertedBmpDir + "\\ConvertedBitmapsFirstImage.bmp");
label2.Text = "עיבוד הנתונים הסתיים";
b1.Dispose();
Then in the trackBar2 scroll event:
private void trackBar2_Scroll(object sender, EventArgs e)
LoadPictureAt(trackBar2.Value, sender);
ConvertedBmp = ConvertedBitmaps[trackBar2.Value - 1];
ConvertedBmp.Save(ConvertedBmpDir + "\\ConvertedBmp.bmp");
mymem = ToStream(ConvertedBmp, ImageFormat.Bmp);
backTexture = TextureLoader.FromStream(D3Ddev, mymem);
scannedCloudsTexture = new Texture(D3Ddev, 512, 512, 1, Usage.Dynamic, Format.A8R8G8B8, Pool.Default);
timer1.Stop();
Button1Code();
timer1.Start();
The same i did with the trackBar1 scroll event.
But the result in trackBar2 i'm getting without using the grayscale convertion is this:
You can see that the color that make the scan now is more yellow or green/yellow and not the same like it is when i'm using the trackBar1.
I can't figure out where the problem is:
1. Maybe since the Bitmaps in the variable array bitmaps are all Format32bppArgb ?
2. Maybe they are Bitmaps and not Gif types like the images in trackBar1 ?
If it does working good with the gifs in trackBar1 scroll event then the whole code in the new form ScanningClouds is working fine so i will not add to here the whole ScanningClouds form code since it's long.
The problem is somewhere with the Bitmaps formas or bits in the variable bitmaps.
Maybe they are not the same or the right Bit Depth or maybe they are Bitmaps and should be Gifs.
bitmaps = ImagesComparison.get_images_with_clouds(b1);

I think not sure but i think the problem is that the images on my hard disk i'm using with the trackBar1 scroll event are Gif type and the images i'm using with the trackBar2 scroll event are 15 Bitmaps.Hi,
"But it didn't work it's just turning them to black gray scale colors not what i was thinking about."
If you want it to be colored, you'll need to create a color-palette for the 8bppIndexed bitmaps. The keyword for this process is "Color-Quantization".
The whole yellow-green pie you get is from the wrong format. If you convert the 32bpp bitmaps to 24 bpp bitmaps, you loose the alpha channel ("transparency"). You can manually set one color to "transparent" with the mMakeTransparent-method
of the Bitmap class, or simply use gif-images (they are 8bpp with a transparent "key"-color)

My iPad does not find the printer. I have tried the HP app and it works, but in any other app the printer is not seen. How do I get this printer visible to the iPad. All my other network computers find and print with out a problem.
hi
could you tell us what the other app is please -
Greetings, I am working in Final Cut Pro 7. In the timeline some clips show as offline. I tried going to sequence and reconnecting to media but it does not work. I can still see the video in the timeline and work with it. It just has the red box. Thanks! Olga
If the clips are not actually missing, you could try to refresh the timeline by using cmd-0 and then going to the timeline options tab. Then select name only where it says "thumbnail display". Press ok to accept the change, then repeat the process to add thumbnails back to your timeline.

It's a 32-bit. I have tried to install both the iTunes 32 and 64 bit, nothing happens after I click on the iTunes installer. It was working fine but after it stopped working (it would just be a white screen), I uninstalled. I tried to run the setup as an administrator and turned off my antivirus and firewall too, but it's not doing anything. I tried to restart the laptop and also tried another account on the computer, it did not work. This is a new Toshiba laptop with Windows 8.
When I say it does nothing, I mean nothing. No popups, no screen flicker, absolutely nothing. All my other files work fine, it's only this.
Thanks.It worked fine but I think the update may have caused this problem, not sure if there is some fix. The install exe does not even open.

Why is my Apple ID not working in iTunes or App Store on my iPhone? When I try to buy apps or music it asks for Apple ID so I enter my info and nothing happens. When I go to settings/iTunes App Store my Apple ID is not there. When I enter my ID and password it does not save or link to account. I do not have this problem with iPad ID is stored and can be used in App Store and iTunes. I have just upgraded to 5c and it's still a problem.

When fist setting up your new iphone you will be asked to log in with an apple id and password. If this did not happen you can then do as you suggested going to settings to itunes and app store and add your apple id login. This apple id login must have already been created for the iphone to accept it. If this apple id is already created but is not being accepted by your iphone you then should shut down your iphone and restart the device.
Good luck. -
My iPod dispalys this message:
"Connect to a computer. Use iTunes to restore." When I connect to a computer, iTunes doesn't recognise it. The iPod 5th Gen does not work at all. How do I fix my iPod without losing any data?
I have seen the Apple webpage suggesting the "five R's" (including restore). Before doing anything, I want to be sure that restoring or any other action is not going to delete or risk my data.
I would be very grateful if anyone can suggest a fix for this problem, in a way that will not risk my data.
Thanks in advance!Did you try a hard reset with the iPod still connected to your PC? Have you tried multiple USB ports, preferably high powered USB 2.0 ports?
To do a hard reset, first make sure the hold switch is in the Off position, then press and hold both the Select (Center) and Menu buttons together long enough for the Apple logo to appear.
Have you also worked through each and every single troubleshooting suggestion in this Apple support document?
iPod not recognized in 'My Computer' and in iTunes for Windows

My iphone 6 connects to the car via bluetooth, the music works good, but the phone calls does not work. It looks like it is working but doesn't. I have tried in my Hyundai Sonata and a Dodge Dart rent car and get the same results. I updated the last 8.0.2. It worked the first day i had the phone, and then i updated to Ios 8.0.2 and it quit working.
Now when i get in the car, it acts like it is connected and makes the same call it was on after syncing to bluetooth, but it really isn't on a call. This is happening on both cars.
Does anyone know if this is the phone and i need to take it to Apple or if there is an issue that Apple is working on getting a fix for?
My son in law has the exact same phone as me, we both got the on 10/6, he had a Dodge Dart and his is working via bluetooth.
Someone HELP please, as i consider this a safety issue by not having my calls go to bluetooth.We had the same problem, but figure out the solution.
You MUST have at least 1 song added to your ITUNE! After you add a free song, then everything else should work as normal!
Hope this helps! -
My ipad mini is not being recognized by the new iTunes update that just came out about a week ago it worked fine till the update I have windows 8.1 does anyone know how to fix this problem and I just bought my ipad mini
I found this is another thread - same issue.
Re: iTunes has stopped working. Why?
Sep 11, 2013 6:07 AM (in response to thurdy)
Resolved!
After contacting Apple, I received a reply from their engineers:
Copy QTMovieWin.dll from: C:\Program Files (x86)\Common Files\Apple\Apple Application Support
to: C:\Program Files (x86)\iTunes
And that did the trick.

Trying to install iTunes on Windows 8.1. Apple Application Support was not found. Error 2. Uniinstall iTunes and try again, does not work. Is there a fix?
Let's try a standalone Apple Application Support install. It still might not install, but fingers crossed any error messages will give us a better idea of the underlying cause of the issue.
Download and save a copy of the iTunesSetup.exe (or iTunes64setup.exe) installer file to your hard drive:
http://www.apple.com/itunes/download/
Download and install the free trial version of WinRAR:
http://www.rarlab.com/
Right-click the iTunesSetup.exe (or iTunes64Setup.exe), and select "Extract to iTunesSetup" (or "Extract to iTunes64Setup"). WinRAR will expand the contents of the file into a folder called "iTunesSetup" (or "iTunes64Setup").
Go into the folder and doubleclick the AppleApplicationSupport.msi to do a standalone AAS install.
Does it install properly for you?
If instead you get an error message during the install, let us know what it says. (Precise text, please.) -
My Ipad did work on my wireless at home and works on other wireless but no longer at home. My IPhone works at home and others can use the wireless> Confused that it did work and now does not?
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398
Additional things to try.
Turn Off your iPad. Then turn Off the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
On your iPad go to Settings > General > Reset > Reset network settings and see if that enables you to connect.

HP ENVY 4500 e-All-in-One Version 3.2.1 does not work on iMac 20-inch, Mid 2007. Only recognizes scanner not USB printer.
I would like to print via the USB connection instead of wireless (the wireless does work, and the scanner works via USB).
I tried connecting the printer directly (via USB) to my MacBook Pro laptop and it worked just fine.
How can I make this printer work on my iMac?
I spent 4 hours on the phone with HP and we did every combination of installation of drivers ad nausum and their bottom line is that it is a Mac problem.
Any help would be appreciated. Will be sending this printer back to Amazon if I can't make it work on the USB.
I am open to questions or suggestions
Thanks,
ChetAfter 4 hours on the phone with HP and another hour with Apple (Mavericks support) no real solution other than check everything (removed everything from Login Items, removed all HP software anywhere in the system reboot, reinstall printer) then when nothing worked for the 4500, did an OS Reinstall (boot with CMD+R).
The Mavericks support group did open an incident (# 542875311) and I will update it when I figure out how to find it on the system.
My feel is that the base problem is that somewhere between the HP-Inkjet-SW-OSX-Mavericks_v12.34.49-2 package and the Apple HP Printer software in the Library (version 2.16.1) the app for printing via the USP Port just does not get installed for the mid 2007 20 inch iMac. The scanner is recognized on the USB Port and the Printer works fine on Wi-Fi. I have too many devices to burden my home network with anothe device. Also, every time I put any HP Printer on Wi-Fi, my router (Netgear N600 WNDR3400 running 12 to 20 devices depending on who is home) gets wonky (but that's anothe story...).
Additionally, when I attach the HP Envy 4500 to my MacBook Pro (2010) it works perfect - print and scan via the USB prot and both functions show in the System Preferences - Printers and Scanners just as expected and just as the 3050 does.
