Could you help me to control a DC motor with the parallel port and windows 2000?

I have labview 5.1 and i want to control my application throught the internet

I would recommend upgrading to LabVIEW 7.0 for a couple of reasons. First, LabVIEW 6.1 introduced remote front panels which allows you to control a VI through a web browser. Setting up remote front panels is very simple and that alone is worth the upgrade. As far a using the parallel port you can use VISA to send/receive commands via the parellel port if you are using a motor controller with a parellel interface. If you are talking about using the port on a bit level to control the motor, LabVIEW 7.0 ships which an example of how to do basic digital input output with the parallel port.

I was downloading the new IOS and message could not find Iphone appears in Itunes window - Now my my phone is stuck with the power symbol and an arrow pointing to the Itunes symbol, I have tried turning off my phone and turning it back on but nothing seems to work

So when you plug it into your computer, you're not getting a message in iTunes that it has discovered a phone in recovery mode?
Reboot both the computer and the phone and try again.

Hi my iPad 2 charger the one with the USB port and a USB cable doesn't work anymore I've changed fuses even tried a different cable no luck HELP!!!

Sounds like you need to restore your Apple TV to factory settings.
See this Apple document:

You will need to use the "Micro USB Cable" to restore it to factory settings.

How to control an Xserve G4 with the serial port

I have an Xserve G4 first generation, and was wondering exactly how you would go about connecting to it via serial port incase I need to change something when there is a network issue. I have looked around the internet without much success. It has Leopard Server on it, so Apple says the baud rate is 56700, and 8bit, no parity. So that's all set in the client machine, which is a MacBook Pro with a USB to Serial adapter on it, which shows up in Zterm. Once I'm in Zterm, it just sits there, and pressing enter doesn't prompt a log in. Does anyone see what else I'm most likely missing?
Thanks

Thanks for the reply Cemelot. Yes, I did create a profile in ZTerm. This is what I have it set to.
I also read that you're supposed to run the command "/usr/libexec/getty serial.57600 /dev/tty.serial" on the Xserve itself. It made no difference if I did that or not. I also checked to make sure tty.serial was inside /dev/. Anything else I'm missing? Thanks again.

Help! My iPad 3 is stuck with the Apple Logo, and iTunes is unable to detect my iPad.

I have a iPad 3 Wifi+Cellular. I just turned it on, and it's been on the Apple logo for 1 hour! What should I do? I thought I should go to iTunes, to see if I can do anything. But iTunes is unable to detect the iPad! I've tried all my USB ports, numerous times, and it is not working! What should I do? (I think I'm out of Warranty).

First try a Reset ( No Data will be Lost )
Press and hold the Sleep/Wake button and the Home button at the same time for at least Ten seconds... (But can take Longer)... until the Apple logo appears. Release the Buttons
If no joy... Try a Restore...
1: Connect the device to Your computer and open iTunes.
2: If the device appears in iTunes, select and click Restore on the Summary pane.
3: If the device doesn't appear in iTunes, try using the Steps in this article to force the device into Recovery Mode.

Could you help me about table control .. ?

Dear All,
I've a problem in table Control.
I put table control inside tab control (there are many tab in one screen where one tab has one table control).
The schenario of the program, i wanna use table control to maintain the value from some table.
So certainly it has insert/add, delete function.
As we know to do one function in those e.g. add record button, we need specify some code on that button.
So ..
Once when that button is pressed, we can check what button is being pressed using that code.
And it can run well.
But this is the strange one, if i have schenario like this :
1. I click add record button
    I will get the add code through ok_code/SY-UCOMM variable.
2. I scroll down/up the table control.
    (THIS IS THE WEIRD), the ok_code/SY-UCOMM variable still keep having add code. So every we scroll down/up, application also will add one record.
Could you help me to make ok_code/SY-UCOMM blank in every time i scroll down/up the table control ??
Or could you help me how to i specify the code for scroll down/up the table control so I can identify when user is scrolling down/up the table control??
I really need your guidance/suggestion how to overcome it .. ?
Many tks for all your attention.
Best regards,
Daniel N.

Could you help on Hospitality services

Hi Friends,
As our client is going to implement SAP in their medical services unit.
Could any one send me the organizational structure/ chart of accounts list for hospital.
Regards,
Suresh

Hi Suresh,
Regarding the organizational unit for hospital, following would be my comments.
You model the organizational structure of your hospital using organizational units (OUs) that you bring into relation with one another. Whenever you create an organizational unit, you assign an organizational category to it. The organizational category determines which organizational units can be brought into relation with one another. You can define organizational categories of your choosing in Customizing for IS-H.
Examples of such categories are:
u2013 Clinic
u2013 Department
u2013 Care unit
u2013 Admitting facility
u2013 Outpatient clinic
You create an organizational unit with the appropriate organizational category for each organizational unit in your institution. The organizational category determines which attributes you can store for an organizational unit.
Examples of such attributes are:
u2013 Outpatient treatment
u2013 Departmental assignment
u2013 Nursing assignment
u2013 Supports inter-departmental bed assignment
Use: The organizational structure you define in the IS-H System is used in the following areas:
Patient assignment: The attributes of an OU determine whether it can be used as a departmental, nursing and/or treatment OU in the patient assignment.
Service entry/billing: In the master data of an OU, you can specify the service that should be automatically entered and billed for a patientu2019s stay in this OU. The organizational structure determines whether you can store different services on different levels of the organizational hierarchy.
Statistics: Statistics evaluate specific data in relation to organizational units, for example the patient census, and total the determined values according to the organizational hierarchy.
Service transfer into Controlling: To be able to transfer services into Controlling, you must first have assigned organizational units to cost centers. You should, therefore, also include service facilities such as laboratories and X-ray departments in the organizational hierarchy, so as to be able to post to the corresponding cost centers when carrying out internal activity allocation.Prior to creating an organizational structure, you should analyze which results you require in the respective areas and create the organizational structure accordingly.
To model the organizational structures of your institution in the system, you create an organizational structure. To do this, work through the following activities in the order specified.
Process Flow
Create organizational units
Maintain the organizational hierarchy
Set up inter-departmental relationships
Maintain organizational unit-to-building unit assignments
Release the organizational structure
Set up organizational unit identifiers
Chart of accounts to be used for IS-H will not be a raedy made chart of account but you will need to finalize this by understanding with the client. They must be having some traditional chart of account which must be in use currently. That could be a good point to start with.
Hope this helps you and let me know if you need any other information.

Brightness control does not work with the bluetooth keyboard connected on my iPad2. Please someone could help me ?

Brightness control does not work with the bluetooth keyboard connected on my iPad2. Please someone could help me ?

Julien-
I have the Apple MC184LL/A Bluetooth Wireless Keyboard. The brigtness control works with mine, as do most of the other functions.
Try cycling the keyboard off and on. Hold the power button until the green LED goes out. Then press it one more time to turn it back on.
You might try resetting the iPad's network. Go to Settings-General-Reset-Reset Network Settings. Then you may need to reconnect your WiFi and Bluetooth.
If that doesn't help, try resetting/rebooting the iPad. Hold both the Home and Sleep buttons for several seconds until the Apple logo appears. Ignore the "Slide to power off" arrow. The iPad will restart in a couple of minutes. Resetting this way will not hurt anything, and sometimes clears up mysterious problems.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

First, be aware that Numbers is not MS Excel, and Excel is not Numbers. Features available in one of these two applications are not necessarily available in the other.
LINEST in Numbers works somewhat differently from what you describe. The function is well described in the "iWork Formulas and Functions Help" document, available through the Help menu.
I'd start there, with a search for LINEST.
