Can I enable and disable the system speaker under program control?
I'm using LabVIEW 2010.
The PC is running Windows XP Pro.
Thank you

Is there a method in labviewto dynamically save and change the monitor resolution under program control?

Is there a method in labview to dynamically save and change the monitor resolution under program control? I have another application that runs on another monitor. I would like to change the monitor resoultion to 640x480 on program startup, and then restore the monitor resolution back to the user's settings on exit. Can this be done?

Have you already done this manually? I've seen Labview scale front panels very strangely when changing resolutions...

I have a problem with my iPhone 5 stopped working the sleep / power and simultaneously refused to obey the HOME button. I can not use either one or the other. I can not enable or disable the device, display lights up when you plug the charger. same display works fine as it is surprising. or maybe someone knows what is the reason for this? is there any way to solve this problem?

More than likely its a hardware issue, I have never encountered such a problem and best bet is to just go get it replaced. If you have insurance on your device apple will replace it as long as there was no water damage, if you dont have insurance they will charge $200 more or less. Hope you get it fixed

Enabling and disabling the button in the multi record block

hi all,
i am using
Forms [32 Bit] Version 6.0.8.24.1 (Production)
Oracle Database 10g Release 10.2.0.1.0 - Production
i have a multi record block each block contains a button(button is to approve the record in terms of changing the status)
i have the items like date,remarks and button
the button should be enabled if the remarks is not null otherwise it should be disabled.
for this in pre-record trigger i have written
if :record is null then
   set_item_property('button',enabled,property_false);
else
      set_item_property('button',enabled,property_false);
end if;what problem is enable and disable is impacting on all the buttons in the block. in other words if first record's remarks is null then all the records button is disabled. if first record's remarks column is not null then all the records of the button column is enabled.
i have to make enable and disable the button for the corresponding record.that means if first record's remarks column is not null then only first records button should be enabled others should be disabled.
Thanks..

You need to set the No. of items displayed to 1 as Ammad had said, additionally you can set the X and Y Position (Just Y will do and having fixed X) of the button depending upon the current record.
can u explain this part alone bit more (setting the position of x and y)You need to calculate the variable Y_POS depending upon the current position of the cursor that is the current record.
You can find the current record Y_POS using combination of
V_CURRENT_RECORD := :SYSTEM.CURSOR_RECORD;
V_TOP_RECORD := GET_BLOCK_PROPERTY ('BLOCK_NAME', TOP_RECORD);
V_ITEM_Y_POS := GET_ITEM_PROPERTY ('ITEM_NAME', Y_POS);
-- Also needs to add the Y_POS of the relative other items in the muti-record block
V_HEIGHT := GET_ITEM_PROPERTY ('BUTTON_NAME', HEIGHT);
-- Note :- TOP_RECORD Returns the record number of the topmost visible record in the given block.
V_Y_POS := V_ITEM_Y_POS + ((V_CURRENT_RECORD - V_TOP_RECORD) * V_HEIGHT);
-- You will need to add Distance between Items in records if anyThen you can Set the current Y_POS of the button.
SET_ITEM_PROPERTY ('BUTTON_NAME', Y_POS, V_Y_POS);
[/code[
Hope this helps

Messaging Server 3.x: Is there an option to enable and disable the ETRN function?

Is there an option in Messaging Server to enable and disable the ETRN function?

Yes. You can add the option for enabling and disabling the ETRN function by
modifying the code in the file 

server-root
bin/mail/admin/html/SMTPChannelOptions.html

The original code to be modified will appear as follows: 



Yes

No

Modify the code to look like this: 



Yes

No


Yes

No

Making these changes will create an extra option to enable and disable the ETRN
function on the SMTP Options page in the Administration Server.

Yes, this is possible. In Cisco Webex Administration->Settings->Audio you can choose your audio (system-wide) options:
WebEx Audio:
Call In and Call Me service – Enables users to attend a teleconference by calling specified phone numbers or by receiving a Call Me call from the system.
Call In – Enables users to attend a teleconference by calling specified phone numbers.
OFF – Disables all calling features.
Voice connection using computer
ON
OFF
See also this section in the administartion guide.

Can you enable and disable windows task bar

I there a dynamic way to enable and disable the windows task bar?

I am not clear on a way to do this, but if it were possible, you would have to make calls to Windows SDK. You would use the Call Library Function Node to access one of the Windows System DLLs to do this. I would suggest checking http://msdn.microsoft.com. This is a great resource for SDK related issues.

Enable and Disabling the Network Adapter with domain user (Standard User)

Hi Guys.
We setup a active directory in our organization. Added client systems(Windows 7 and Windows 8) to the Domain. Domain users are accessing the system with standard users permission. I don't want to give Administrator permissions. But user should able
to Disable and Enable network Adapter without giving the administrator permissions. Please suggest .
Thanks in advance for the help :)

Hi,
According to your description, my understanding is that you want the standard user has the permission to disable/enable network adapter.
I recommend you to implement this function by group policy:
User configuration - Administrative Templates – Network - Network connections
Enable this policy:
Ability to enable/disable a LAN Connection
Besides, you may consider of joining users to Network Configuration Operators Group, detailed information you may reference:

IOS app switcher *can* be enabled and disabled

Inadvertently I've discovered that the app switcher can be turned on and off, contrary to most reports I've seen. I searched the boards, but couldn't find any past mention of the trick, so here it is: double tap while on the lock screen. This toggles the app switcher on and off, at least on iPhone 4 running 5.1.1.

Well, there's no such thing as a "textedit" file, they're just plain text files. There are many text editors for iOS, and I've gone through quite a few (I tried the early ones and as newer, better ones came out, I'd buy into them). My current choice is iA Writer. There's also an iA Writer for the mac, so the two can keep files in sync. This can use iCloud or Dropbox. When you get a text file from iA Writer to a mac, you can then open it with TextEdit or any other text editor.

Can i export a list of all the webpages in my site, enabled and disabled?

Hey Guys,
Can i export a list of all the webpages in my site, enabled and disabled?
I saw you could view all pages in the advanced view - but i am not sure if you can then export that as an excel file.

hey Liam -
but ftp doesnt show you what is enabled and disabled.
also I don't think you can export an excel file from this?
Pretty much i want this list - in an excel format!

Hi,
If you want to remove the add-ins of Office 2010 programs, you need to remove it from control panel.
For example, if you use Excel, please try to follow the link to delete the add-ins:
http://office.microsoft.com/en-us/excel-help/add-or-remove-add-ins-HP010342658.aspx
If I misunderstand something, please let me know.

Accessing bits of the data bytes and enable and disabling

Hello i want to send data byte to the CAN and enable and disable one of its bits how to do?

Hey Uday,
I am unsure of what CAN device you are using, as well as what type of programming language you would like to develop in. With that being said I will assume one of our PCI CAN cards and that you will be using LabVIEW to program. Please take a look at the NI-CAN manual for help on programming your CAN card, specifically with reference to chapter 7.
Thanks again and have a great day!

AirPort Extreme extends my network and has worked well for three months. Now it can no longer extend the network and flashes Amber. I have restored to factory settings moved it closer to time capsule and rebooted the system without luck

i have a blinking Amber on my extreme now and it cannot extend the network. It was working fine and nothing has changed. I have restored to factory settings moved it to another room and rebooted the system without luck. Any suggestions

What OS are you running?
Please give me a screenshot of the current AE setup..
I strongly recommend if you have issues.. take control of all the variables. Apple routers have too much auto..
Here is a list that I use for setups when using Yosemite.. but it relates to any OS.
You will need to factory reset again to get going.
Factory reset universal
Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
Then redo the setup from the computer with Yosemite or whatever you are using.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg AEgen5 for basestation.
Use AE24ghz and AE5ghz for wireless on each band, with fixed channels as this also seems to help stop the nonsense.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the AE always takes the same IP address.. this is not a problem for router but if the AE is bridged you can have trouble.. Try using the static IP method or control it via the main router dhcp reservations.
4. Check your share name on the computer/s is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
6. Set up the extend to the Express using 2.4ghz and then see how good or bad the connection is.. this is better in the old v5 utility but if you hover your mouse over where it shows connection an extra chunk of info comes up.
I have specifically used 5ghz to make the extend.. because by testing it works better.. but do not be fooled.. this good connection is poor.. the RSSI.. which is difference signal .. at -79dbm is down the bottom of the stable.. and it drops out on a daily basis.. you want to see that signal around -60dbm at min.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
