Why the itunes does not take my ipod 4g
why the itunes does not take my ipod 4g
this worked for me, below.
from:
http://docs.info.apple.com/article.html?artnum=93716
Reinstall the COM interface for the iPod Service
1. Quit iTunes and any running iPod Updater.
2. Click iPodService.exe in the Windows Task Manager window.
3. Click End Process.
4. Click Yes.
5. On the Start menu, click Run. Note that the Run windows may appear behind the Windows Task Manager window.
6. Enter this text (including the quotation marks):
"C:\Program Files\iPod\bin\iPodService.exe" /service
7. Click OK in that window.
8. On the Start menu, click Turn Off Computer.
9. Click Restart.
If the iPod is not working with iTunes or the iPod Updater, proceed to the "Quick Fix" section below. -
Do anyone know why the desktops do not show? Is this a bug?

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

Howdy inshaf1991,
Thanks for using the Apple Support Communities.
From your post I understand that your iPhone is not being recognized in iTunes on your Windows PC. In order to help resolve this issue, please follow the directions in the article below.
iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support
Have a good one,

Also, iTunes does not detect any device connected to the computer.
Hi, Arthur330.
Thank you for the question. I am unsure if you are having the issue with your device not being recognized on a Windows or Mac computer so I will include the troubleshooting articles for both below.

Why the Image is not showing on Report at runtime?
Post Author: azharrahi
CA Forum: .NET
I am working on a web site which was developed in ASP.Net 1.1. This web site also contains Crystal Reports version 9.
Now I have loaded the web site in Visual Studio.net 2005 and hence in ASP.Net 2.0. Still the Crystal reports version is 9.
Everything is ok and Crystal reports are showing data properly.
But one thing is very strange and annoyable.i.e. When I insert image on Crystal Reports through right click-> Insert->Picture, the image is shown in the design time preview of report, but when I load the Crystal Report on .Net control CrystalReportViewer and run the application, the Image is not displayed. The problem becomes more strange when I Export the Crystal Report to PDF file and MS Excel. Strangely the Image is also exported there and is displayed. Whats the problem? Why Image is not displayed on the CrystalreportViewer of the form on run time and why on exporting to PDF file and MS Excel, it is displayed? Can any body tell me whats the problem behind of not displaying image on runtime?
At least it means that Image is embeded and loaded on runtime. Only now viewing. Only a blank Picture box displayed.Post Author: Argan

A couple things can cause this.
Right click on the red x to find out the name of the png file. Search the web server for that png and make sure that the asp worker has access to it.
The other is a image handler issue. Search the kbase for Red X NET 2005 and you will find a kbase or two that addresses this. -
Why are declined events NOT showing on iPhone iOS7 (setting is marked to "on")
Apparently I and some of my colleagues are having the OPPOSITE issue from most.
We are syncing with Google Calendar.
We have set "Show Declined Events" to ON
Declined Events are NOT showing on iCal.
Any ideas?
Thanks.
RicheyI noticed this too. I have a Google Apps for Business account through work.
This happens when I have Gmail configured as ActiveSync. But when using CalDAV - it isn't a problem. Does anyone have a solution or more informaiton on this topic? -
