how can i verify that the network or firewall is not blocking access to port 5223?
Talk to someone who knows something about networking and/or firewalls on an appropriate forum.
Configuring your network and/or firewall is beyond the scope of this forum, which is devoted to issues using the iPhone.

How can I verify that the PCI-6534 is using all of its onboard memory?
When using a PCI-6534 under Windows 98 with NI-DAQ 6.9, I need to transfer a small buffer (8126464 bytes) to the adapter, and get it into the onboard memory. The board is configured for 32 bits output, and I'm using handshake mode. DAQ_GET_DEVICE_INFO tells me that there is 33554432 bytes for each Group. DIG_Block_Check shows that 2031587 words (8126348 bytes) are remaining to transfer. Is that in the PC system memory or the PCI-6534 on board memory? How can I tell if it is safe to reuse the (PC side) buffer? Also, How big is the FIFO on the PCI-6534?
When you call DIG_Block_Out, NI-DAQ first downloads your data into the 6534 memory. Only after the download is done (which should happen at about 80 MB/s) it starts outputting data and DIG_Block_Out returns. So it is safe for you to reuse your PC memory buffer as soon as DIG_Block_Out returns.
This is assuming your entire buffer fits in memory. If it doesn't, NI-DAQ will download all the data that fits and start the transfer, and as more 6534 memory becomes available the DMA channel will fill it up.
The 6534 has a 16 sample FIFO and an additional 32 MB of memory for each handshaking group. So for 32-bit transfers you can fit 8 MSamples, for 16-bit transfers you can fit 16 MSamples (per group), and for 8-bit transfers you can fit 32 MSamples (per group) in the 6534
memory. -
How can we know that the Rule is Generated or Not?
Hi,,
After creating the Risk , its suggested to click on Generate Rules Button to Generate the Risk.
But my question is that how we can know whether the risk is already generated or not..??
Any table or any change history for this.
As I can see even after generating the Rule the last update date for the risk is still the same.
Someone please help me !Hi,
Rule ID numbers are just identifiers for different combinations in same risk. It is just serial number assigned to the combination.
Example:
Risk: RISK01
Function: FUNC01 Function: FUNC02
Action: ZU01 Action: XU01
ZU02 XU02
Rule ID: 0001 for ZU01 and XU01
Rule ID: 0002 for ZU01 and XU02
Rule ID: 0003 for ZU02 and XU01
Rule ID: 0004 for ZU02 and XU02
But if you remove action ZU02 and XU01 in your update
Remaining
Action:
ZU01
Action:
XU02
Rule ID: 0001 for ZU01 and XU02
So it will just update the respective risk with same rule id assignment to new combination.
To achieve more clarity try to build one risk in you system.
You can definitely go into the risk to see if the new rule generated has changes reflected as per update or not. Try this all with example so you would have clarity.

How can I verify that the Trace and Points tables are being updated?
I am using MSQuery to look at the data in my Citadel database, but it appears there is no data in the database. There are transactions in the A/E viewer. I am totally new to lookout and citidel. TIA.
Hi Jeff,
Here are some old articles on accessing Citadel 4 data from MSQuery and MSAccess. These should at least give you a starting point:

http://zone.ni.com/devzone/conceptd.nsf/webmain/0A3D4EEAC9208065862568080072DB9F
Also, do you have NI-MAX? You can check for data in there too.
Hope this helps,

How can I verify that I properly "SIM-unlocked" my IPhone 4?
As part of my service plan with Bouygues (France), I got an IPhone 4 which is "SIM-locked" and can not be used with another telephone operator.
After 3 months it is possible to organise the "SIM-unlocking" of the phone, free of charge.
I did so by contacting the customer support and performing the appropriate procedure with ITunes. Everything seems to have gone right, the IPhone 4 is as great a phone as it was before,
my question is simple, how can I verify that the phone is actually unlocked? a menu in the phone for example?
PatrickJust put a sim from a different carrier in and try it.

How can I verify that my App data is actually stored in the iCloud. I can see and access my notebook, contacts etc. on the iCloud website, and I can see my photos in a folder on my Windows-based desktop compter (iCloud/Photostream). But no app data.
With Dropbox, I can actually see all of my stored files. With iCloud, it seems, I'm supposed to just trust that Apple has my back. Short of deliberately trashing my app data and then attempting a restore, is there no way to check the data?You can't access them on Windows (unless you have iCloud enabled Windows programs) and I don't think any are, yet.
iCloud data is accessed via Apps/Programs, the Windows programs vendors will have to step up (just to make it worse Microsoft have not yet enabled their Mac programs, such as Office yet) I doubt that iCloud access is much of a priority for them, complain to MS, when enough Windows users complain maybe they'll do something. -

How can I verify that backup media is workable?
Dear Experts,
I do backup SQL backup on Hard Disk everyday, then use NT BACKUP to external TAPE DRIVE, report is showing no any error and completed backup, questions, how can I verify that backup media is workable?
Best and Regards,
wilsonHi Wilson,
In SQL Enterprise manager , there is an option to verify your backup .
You need to enable this verification by checkting the box. If this option is enabled , after taking the backup , it will go for the verification and give you the result .
If it is verified successful, it means, the backup has been written fine in the Tape/HDD , and it will be
restored fine.
Even if this verify option is done, SAP reccomends to perform a test restoration of the backup to a test
system in order to make sure everything working fine .

How can i indicate that the table columns have different size?
How can i indicate that the table columns have different size?
It is because i have a table that has several columns....but i would like to have the possibility to indicate the size for every column....could somebody help me please?
Thanks,
MaryHi,
don't know as much as I should about JTable, but it seems that using yourTable.getDefaultRenderer() could help you: if I clearly understood the javadoc notes, it returns an object inheriting from JLabel, so you should be able to use setHorizontalAlignment(int align) on it... no time to verify this, but I'd be thankfull if you tell me the results !!!

Hello. I would like to write async tcp client and server. I wrote this code but a have a problem, when I call the disconnect method on client or stop method on server. I can't identify that the client or the server is no longer connected.
I thought I will get an exception if the client or the server is not available but this is not happening.
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.SafeInvoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
How can I determine that the client or the server is no longer available?

Have you debug these two applications? Does it go into the catch exception block when you close the client or the server?
According to my test, it will throw an exception when the client or the server is closed, just log the exception message in the catch block and then you'll get it:
private async void Process()
try
while (true)
var data = await this.Receive();
this.NewMessage.Invoke(Encoding.ASCII.GetString(data));
catch (Exception exception)
Console.WriteLine(exception.Message);
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.
By the way, I don't know what the SafeInvoke method is, it may be an extension method, right? I used Invoke instead to test it.

How can I make that the cursor of a table ...
Hello,
how can I make that the cursor of a table (on the frontpanel) go to the starting position? I have placed a table that give back the number of the row if I doubleclick a row on the frontpanel, but when I restart the vi the cursor of the table is on this position. If I have many informations in the table and after restarting there are just one or two, I can`t see this information without scrolling to the top of the table. I want that the cursor (that I see) is at the first row. How can I make it?
thankyou
SchwedeHello,
Sorry, I forgot to attach it in the previous post.

I am selling my Mac Mini. I recently purchased OS X Lion. When I restore to factory settings, how can I ensure that the operating system will still be Lion, and not the original operating system, which I believe was Snow Leopard?
If you bought Lion from the App Store, you can't legally or practically transfer it, because it's tied to your Apple ID. Reinstall the original software from the discs that came with the machine.
