Can we capture and filter out wavelengths with the camera?

Hi,
I don't know if somebody can answer this, but is there a method to filter out wavelengths using the lumia camera and capture them? This capability could be applied in the field of biophotonics. So e.g. you make an app that sets the camera to only capture
light that reaches it in the wavelength range of 750 - 1400 nanometer.
The applications of this would be e.g. making an app that displays the body's veins on the screen (similar to devices like the VeinViewer), or an app that estimates the approximate surface temperature of a given hot surface (organic or inorganic). Other
biophotonic applications can be investigated too.
So far I've only taken a brief look at the Lumia Imaging SDK. At a glance, it doesn't seem to offer this capability.

Thanks for the answer.
Is it theoretically speaking possible to have the capability to filter by wavelength? Something like an API that is added by Microsoft? If so then I'll consider adding a feature request to the
dev feedback. If not then there's no point in the request in the first place. I think it would be an excellent way of extending the phone's capabilities beyond what we can currently do with them. In the same vein as the
Ultrascope.

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery. Moments later I turn it back on and the same battery life still appears.

My iPhone with 40 or so percent randomly shuts down with iOS 7 and 6. Often with the camera app stating the phone is out of battery. Moments later I turn it back on and the same battery life still appears. It sometimes happens over and over until I leave it alone for a while (still not charging), and then it works.

I think you might get a new phone instead of repairing it as it takes time and you said the repairing center is far from your living place

How can I capture and take screenshots of all the browser tabs and not only windows ?

This class identifies all minimized windows and take a snapshot (screenshot) of them. I want to take screenshots also of all the broswer for example chrome tabs windows that are open but not in the front. Same idea that it get now the minimized windows but
to get the screenshots of the broswer opened tabs ! What should I change in the WindowSnap class? Since both classes are a bit long I added them to pastebin.com
What i'm doing now is to get all the minimized windows i mean all the the windows in the back if it's chrome browser windows or open tabs if it's program games other windows. This is what i'm doing in form1 constructor:
this.listBoxSnap.Items.AddRange(WindowSnap.GetAllWindows(true, true).ToArray());
int numitems = this.listBoxSnap.Items.Count;
for (int i = listBoxSnap.Items.Count - 1; i >= 0; i--)
string tt = listBoxSnap.Items[i].ToString();
if (tt.Contains(" ,"))
listBoxSnap.Items.RemoveAt(i);
listBoxSnap is just a regular listBox1 in my form1 designer.
And this is the WindowSnap class code, it's a bit long code but it's all connected:
I'm not sure what to show here from this class what is the most important part so i added all the class code to a link to pastebin.com:
WindowSnap.cs
What i'm calling/using in form1 constructor from this WindowSnap.cs class is the GetAllWaindows method:
public static WindowSnapCollection GetAllWindows(bool minimized, bool specialCapturring)
windowSnaps = new WindowSnapCollection();
countMinimizedWindows = minimized;//set minimized flag capture
useSpecialCapturing = specialCapturring;//set specialcapturing flag
EnumWindowsCallbackHandler callback = new EnumWindowsCallbackHandler(EnumWindowsCallback);
EnumWindows(callback, IntPtr.Zero);
return new WindowSnapCollection(windowSnaps.ToArray(), true);
EnumWindowsCallBackHandler is:
private delegate bool EnumWindowsCallbackHandler(IntPtr hWnd, IntPtr lParam);
EnumWindows is:
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool EnumWindows(EnumWindowsCallbackHandler lpEnumFunc, IntPtr lParam);
Then i have the class called WindowSnapCollection:
WindowSnapCollection.cs
The problem is in form1 constructor i'm getting only 23-24 windows in the listBox1. When i'm doing this two lines:
this.listBoxSnap.Items.AddRange(WindowSnap.GetAllWindows(true, true).ToArray());
int numitems = this.listBoxSnap.Items.Count;
I see in numitems about 30 windows and after filtering i'm getting 20 windows and i checked that's the correct number of opened minmizied windows i have in this example 20.
Now what i want to do is somehow to get with all this windows in the listBox also all the opened tabs in chrome.
For exmaple i have only 4 opened chrome windows. But in one of the chrome windows i have almost 40 tabs opened !
I want somehow to add to the listBox all this opened tabs also as captured screenshots like i'm doing now with the windows.
This is a screenshot of my program showing what i'm doing and what i get:
So now i have 19 windows captured in the next refresh it will show 20.
My question is if there is any way to capture also all the chrome opened tabs in all the windows if any opened tabs are opened at all ? Now i'm getting only the chrome opened windows captured screenshot. But i want to get also the chrome tabs captured screenshots.

Hi Chocolade1972,
Since this forum is discussing about Windows Forms general like winform controls, and your issue is related with Windows Desktop SDK, I will move this thread to the more related forum.
Thanks for your understanding.

If you paid for what you used then it was not a trial.

I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

I want to upgrade my old airport express to the new express. Can I just switch out the old for the new or must I delete the old network first and start from scratch with the new express?

It is not necessary to delete your old wireless networks first, but doing so may eliminate confusion. If you wish to do that, open System Preferences > Network, and select Wi-Fi from the left column. Click the Advanced... button, then select your old wireless networks and delete them with the "–" (minus) button. Make sure the "Remember networks this computer has joined" remains checked.
OK then Apply.
This prevents your Mac from searching for your previous network which will no longer exist.
A new Express creates an open wireless network that you must select before you can configure it. It appears in your Wi-Fi menu like this:
Select it. AirPort Utility will load and walk you through its configuration.
Edit: If you are really using OS X 10.5.1 as shown in your profile, the above screenshot is not applicable. Instead, select the network called "Apple network nnnnnn" and then launch AirPort Utility.

The easiest way to find out what carrier it's locked to would be to call the store where you purchased the phone.
The phone can be unlocked from any location. However, most carrier have restrictions about unlocking and you have to contact them for details.

How can a show I purchased be incompatible with the latest version of iTunes?
I want a refund, but I can't even figure out how to request one through support. Super frustrated and long time Apple customer.

After a day of trying, both iTunes and my Apple TV are telling me that the episodes of Scooby Doo I purchased are incompatible due to QuickTime. I still don't understand how I purchased something from iTunes that doesn't work with iTunes.
the exact error I receive when I try to play an episode is the following:
"This movie requires QuickTime, which is not supported by this version of iTunes."
Any advice would be great!

Same problem with the mouse, but with the mouse I can leave the cursor in place in the text field and move to the keyboard to type. As long as the cursor is in the field it stays editable.
The problem with the pen is it's in my hand all of the time. I just flip it up under my thumb against my palm to type. So, as soon as I move the pen, the field goes away and I can't type in it. Hoping this is making sense.
My tablet does have the touch function too, and I just found out I can use my finger to tap in the text field, then type. I guess that'll be my solution since I prefer not to leave a mouse set up on this iMac.
I'm thinking now that this is just a problem with the pen itself, and nothing to do with iPhoto. So glad to have this figured out! I really like iPhoto '11! So much easier for me, a simple P&S gal, than Aperture 3. I use iPhoto Library Manager too and love it!
Thanks so much! Debbie

HT1296 How can I capture and save an image on my screen for later retrieval

Is there a way to copy the image to a storage device?

Its easy to take an iPad screenshot. Press & release the Home and the Power buttons quickly at the same time. I have trouble with that so I press & hold the Home button and then very quickly press and release the Power button. Your screenshot is stored in the Camera Roll of the Photos app. Probably the easiest way to get it to your PC is to be using iCloud, or email it to your PC. There are also some wireless sync apps in the iTunes app store that let you send photos from the iPad to a Mac or PC. I use PhotoSync.

The troubling thing to me is the fact that the charger gets extremely hot - according to what you are saying. The charger can get warm and can get fairly warm when the iPad is charging, but it should never get extremely hot. Make an appointment at an Apple Store, take the iPad, the cable and the charger with you and ask them to look at everything for you.

Cannot backup my files / copy my files and folders due to error message " The operation can't be completed because an item with the name ".DS_Store" already exists. "

Hi Apple community!
I have a [rather worrying] problem.
When I try to copy all my files from my documents on my mac [or the entire documents folder] into an external drive, I get this error message
" The operation can’t be completed because an item with the name “.DS_Store” already exists. "
I am not given an option to skip this file or anything else.
But I simply cannot complete the operation!
I have tried deleting a few of the .ds_store files, [both in the original and in the destinations]
but no success.
The same thing keeps happening.
At first, this was just happening when I was trying to backup to my dropbox folder [the one on my mac's harddrive, which gets synced to the cloud],
but then I tried to back up my documents to my external hard drive, and I realized it is giving me the same error message.
So effectively, it seems I cannot backup my files anywhere!
Any help or advice would be greatly appreciated.
Thank you.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, or by corruption of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled on some models, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output and Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

Can we capture and filter out wavelengths with the camera?
