How can I detect whether a TestStand Message box is active from a LabVIEW VI or application?

I'm trying to detect when TestStand Message boxes are active on a local PC from a LabVIEW VI. Does anyone know a way to do this (ActiveX or some kind of "in memory" query maybe)?

Hello John,
the critical thing to do would be to get an engine reference to the Engine by means of a LabVIEW Automation Open VI (look in your activeX functions palette and the help for this item), the input will be an ActiveX reference to the TestStand Engine (browse for the class NI TestStand API, any version will do, and choose Engine from the list). Once you have this reference to the currently running TestStand, the next challenge is to some how access information about the current execution. The only way to reach that object is via getting the UIMessage object and then retrieving a Thread object from the message, and a SequenceContext from the thread... until finally you can access the property "Step". Your best reference in this case is
going to be the TestStand Programmer Help (specifically for the API) and explore the properties and methods of each of these classes in turn.
Feel free to ask if you get stuck.

How Can I Detect Whether the User's Firefox Supports MHTML?

Is there a browser capability property that I could look at to detect whether the user's version of Firefox (including, for instance, an "unMHT" add-on) supports MHTML? Currently we provide reports to our users in this format and want to provide a link to add-on's in case the user cannot actually view the format; but show the report if the add-on or capability is present.

Sorry, you can't detect if a user has unMHT installed.
Have you tested your MHTML files with Firefox and unMHT? <br />
MHTML was never adopted as an official standard by W3C - http://en.wikipedia.org/wiki/MHTML - and from my limited usage of unMHT, it isn't exactly the same as what MS uses with IE. I have had problems displaying a file saved in one browser in another brand browser, and don't remember the specifics beyond IE8 won't correctly display unMHT files even when the file extension is changed from MHT to MHTML. Plus there's a 2nd add-on / extension - Mozilla Archive Format - that some users may have installed for MHTML files.

How can I tell whether or not a photo I delete from iPhone will also be deleted from iPhoto on my Mac?

I would like to download the new iOS, however when I go to do that, a message tells me that I cannot because I need 4.6 GB of storage in order to install it. I only currently have 864 MB of storage available on my 16 GB iPhone 5s.
The storage problem would be fairly easy to solve through deleting photos and/or videos, as the Photos & Camera app shows a current usage of 5.7 GB. I am perfectly comfortable deleting photos off my iPhone if I know that they will remain in iPhoto on my Mac. However, when I select photos to delete, the phone warns me that the photo(s) will also be deleted from Photo Stream on all my devices. I tested this with some photos I didn't care about (whether or not they got permanently deleted from all devices), and it is perplexing, because even though the iPhone warned me that the photos would be deleted on other devices, they have not deleted out of iPhoto on my Mac. I even Quit iPhoto and re-started it, but the photos are still there. Why would the iPhone claim that the photos would be deleted from other devices, but yet clearly the photos are not being deleted from my other device? This leaves me confused and unsure.
Meanwhile, if I select a bunch of photos then click Delete, the phone warns me that SOME photos will also be deleted from Photo Stream on all my devices.
I am very annoyed by the ambiguity of the word "some," and not being able to know for sure whether or not photos I delete off my iPhone will still remain in iPhoto on my Mac.
I would just like a really clear answer if possible: currently all my iPhone photos are showing up in iPhoto on my Mac. If I delete photos off of my iPhone, will they or won't they be deleted from iPhoto on my Mac?
Thanks if anybody can help.

If the Photos have been moved into the Library (Events, Photos, Faces, Places) in iPhoto on your Mac (either because you did it manually or as a result of iPhoto > Preferences > iCloud > Automatic Import being on) then nothing you do on the phone will delete them from iPhoto on your Mac.
If the Photos are ONLY in the Shared - iCloud section of iPhoto then you risk losing them as deleting them from Photo Stream will delete them from there.

How can I desactivate an "-3 error" message box?

Hi everyone,
The last time I ran my program I got the error message : -3 at an unknown place (see .png).
I had already run it several times (for something like 40h each time) without any problem.
I have only connected and configured the error messages/boxes in some places in my program but not everywhere.
Could someone tell me if this kind of message can pop up when you haven't connected and configured all the messages/boxes? If so, I suppose I just need to configure all of them to avoid this kind of pop up?
Or could I get this kind of message anyway? If so, is there a way to desactivate this kind of pop up window message so that my program doesn't stop (although I understand there has been an error somewhere on the line)

I've got my email folders showing but how can i put back my email messages into the folders from time machine

Into one of the domain accounts, or a specific mailbox in a domain account, that's your choice but:
Remember that you are moving mail over the internet, and you are uploading (slower). If the quantities are large you must use caution.
1. Copy, don't move, in the event of a failure the original will still exist, delete it later.
2. Limit copies to <500 emails
3. Single copy operations are more reliable than multiple.
Take your time.
Thanks, but impractical. Many of the folders have more than 500 emails. Total is about 2 GB (which I have free on iCloud btw)
I tried creating a folder "Archive" in my iCloud, then tried dragging one iMac folder into the new "iCloud > Archive" folder on my iMac. I got the error message:
Some items could not be created:
The IMAP command “CREATE” failed with server error: Invalid mailbox name.

How can I stop the login pop-up box for iCloud from repeating?

I don't use iCloud so I click Cancel in the iCloud login box when I start up my iPad Mini. But this popup box won't take Cancel for an answer and it reappears at least three more times, every 10-15 seconds or so, interrupting what I'm doing - really annoying. Can I stop this pop-up box from repeating like this, and if so, how?

Ah ok that all makes sense. You are correct that would turn off Find my iPhone. Based off the additional info you provided, it seems to me that the password needs to be updated. What I recommend doing next is entering the password when it prompts you to. If the password is incorrect in the settings then Find my iPhone may not be able to find the phone because it does not have the password authenticated.
Then you can turn off any iCloud features you choose not to use with this article and leave only Find my iPhone enabled.

How can I find out if a user has an active session

How can I find out if a user has an active session or sessionObject in the application Server.
When a user logs on to my web-application, I want him to be able to see a
list of all the other users that are also loged on. To do this I need to get a
list of all the session objects avaliable in the sever at that perticular moment?
In J2EE 2.1 I found the class "javax.servlet.http.HttpSessionContext" with the method "getIds()"
that returned all the session Id's. By using the method getSession(java.lang.String sessionId)
from the same class, you could then retrieve the sessionObject.
But these methods are depricated (and want to be able to use the
latest version of J2EE).
Is there any other way to do this?
I'm using JBoss application server.

Check out HttpSessionListener -> http://java.sun.com/j2ee/sdk_1.3/techdocs/api/javax/servlet/http/HttpSessionListener.html
Essentially what you have to do is implement this interface. You also have to register the listener in your web.xml, like this:
<listener>
    <listener-class>
        package.name.YourListener
    </listener-class>
</listener>sessionCreated() will get called each time the app server creates a session and sessionDestroyed() will get called each time the app server invalidates a session. You could have a Map that contains all the active sessions, and a method for printing a list of all of the active sessions.

How can i detect if my PC is not on Network..... Urgent Pls Help Soon !!!!!

Hello Everyone,
We all know whenever we try to connect to a PC which is not on network, we get UnKnownHostException etc..... by which we can detect that the corresponding PC is not an network(intranet/internet)
But when i send a msg from my PC to my PC, it works fine even if the network is down. I hv provided my PC's IP address instead of using localhost or 127.0.0.1 which reduces the possibility that the msg will not be traversed thru the network.
Any IDEA how this works.
Is There any possible way by which i can detect that my PC is not on network or the PC to which i'm trying to connect is not on network .......
Pls help me out, its really urgent as to be implemented in my Project
Thanks In Advance

How can I know whether the Servlet is sending a response!!!

Hello,
My question is this :
How do I know whether that server outputstream is sending me a response or not?
I have opened the Client InputStream to recieve a response from a servlet,but how
can i be sure that i will receive a response from the servlet?
I cud be waiting for an 15 expecting a response but havent received one..
Is there any way to check whether the servlet is sending me a response?
The reason I am asking is this.
I have written a Java Client that connects to a servlet.It has to wait for a
response from the servlet.It will wait for 5 seconds and if this doesnt recieve
a response,it will return back else it will display the response.
I have set a timer on my client for 5 seconds and a timer on the servlet for 15 seconds.
Essentially,when the client connects,the servlet response is held for 15 seconds
and the client tries for 5 seconds.
But the client is unable to exit without a response.The response comes back in 15 seconds.
The client shud have the message 'Connection Timed Out' after 5 seconds.
This means there is an error somewhere.
As the response takes 15 seconds,the client shudnt recieve one.
So,is there a way I can block the servlet response?
I am using threads and Inner classes for the timer purposes..
Please can any one help me?

System.out.println("Received from Client: " + sMess);

try {
for(int i=0;i<15;i++)
System.out.println(i);
DataOutputStream dos = new DataOutputStream(response.getOutputStream());
String sResponse = "Hello Client...This is server sending response";
dos.writeUTF(sResponse);
Thread.sleep(1000);
}catch(InterruptedException e){}

I don't know whether you solve your problem or not! Anyway, I have the same problem. The program hangs when getInputStream is called.
DataInputStream dis = new DataInputStream(request.getInputStream());
If you have the answer, please let me know. Thanks!!

How to detect whether a database was created by Restoring (from SQL Server Enterprise Manager) or by Attaching (from SQL Server Enterprise Manager)

Ours is a SQL Server Express Edition 2008-R2 - Windows Forms based application. We have a backup/restore utility provided with our software which performs some logical checks before restoring a backup to ensure that the backup is functionally valid.
However, our clients often use the SQL Server Enterprise Manager utility to 1) Restore backups or 2) Attach data files (kept aside before formatting) directly. This type of action bypasses all our functional checks and allows the user to restore an invalid
backup.
We want to detect that a database was restored/attached and may be we will stop the software from loading if such a thing happened. We think that this information (attach/restore) should be available within some table of SQL Server itself but don't know the
right location/query.
If any change is required in our software to achieve the above, we are ready to do the same too, e.g. may be we need to store some data at some point of time to make the detection happen, please advise.
So, how can we detect that
A database backup was restored using SQL Server Management Utility
(Note: MSDB.Restorehistory may not be a good option as we have often found this table blank for unknown reasons even after backup was restored and just in case user restores the MSDB from MSDB backup or MSDB template due to a data corruption, may be due to
abnormal shutdown of system, then the RestoreHistory table data is gone)
A database was created by attaching a data/log file using SQL Server Management Utility
Any help in this regard is highly appreciated.

Hi,
For Enterprise edition, we can enable Auditing to audit BACKUP_RESTORE_GROUP in a server audit specification. However, SQL Server audit (fine-grained auditing) feature is not available for the SQL Server Express.
Features Supported by the Editions of SQL Server 2008 R2
http://msdn.microsoft.com/en-us/library/cc645993(v=sql.105).aspx
When a database is attached, SQL Server ERRORLOG will record “Starting up database 'DBNAME'.”
Using ALTER DATABASE OFFLINE and ONLINE will re-open the database files under the SQL Server, the SQL Server error log also contains the following informational message: “Setting database option ONLINE to ON for database 'DBNAME'.”

How can I detect in Business HTML that the app was called from portal?

How can I detect in Business HTML that the app was called from portal?
I need to distinguish whether the application was called from portal (URL iView) or by using an URL outside of portal.
So what I'm looking for is a variable or function that can be used like this:
`if (~within_portal==1)`
do this if called from portal
`else;`
do that if not called from portal
`end;`
For example, can I check in the program that there is a SSO2 cookie from the portal?
I'm using Integrated ITS in Basis 700.

Here is the trick:
if (sapwp_active=="1")
in portal
else
without portal
end;

Hi anybody there who can help me ha..? My phone 5s was stolen 1 month ago..Find my phone is no a big deal, How can i know whether my phone is in use??

Hi anybody there who can help me ha..? My phone 5s was stolen 1 month ago..Find my phone is no a big deal bcz it seems to be wiped out all data including settings. it might be in use somewhere turning new fresh Gadget. How can i know whether my phone is in use??

You would know for a fact if the device is in use, but if you go back to the find my iPhone app in iCloud.com, you can either select to erase it, or place it in lost mode, in which case, once the device makes a connection to the internet, it will automatically go into that mode.

How can i print out old text messages?

how can i print out old text messages?

As Ann said, it does depend on your phone. One third party app that works on many phones (especially older models, but not all phones) is BitPim ( http://www.bitpim.org/ ) but it can potentially harm/brick your phone if you don't know what you are doing - use it with caution. I have used it successfully to get texts and photos off an old flip phone that was deactivated and had no sd card.
Newer smartphones can download apps that will give you the ability to print out texts.

How can I detect a dialog and respond?

I'm having trouble doing something that's probably not that hard. I'm trying to "Print to PDF" a bunch of old AppleWorks documents. When you open a document created in AppleWorks v6 it opens right up, but when you open a document created in AppleWorks 5 you get a dialog box that says, "This document was created by a previous version of AppleWorks. A copy will be opened and "[v6.0]" will be added to the filename."
Right now I open the file and then:
tell application "AppleWorks 6"
        activate
        repeat while not (exists front document)
                delay .2
        end repeat
end tell
When the dialog box pops up, there's no front document so the whole thing freezes until you hit OK. How can I detect this dialog box and dismiss it?
Thanks
PS
When the box is open I ran this and got this result:
/usr/bin/osascript -e 'tell application "System Events" to get properties of windows of application process "AppleWorks 6"'

Hi,
The simplest would be to set the application preferences in the script.
Like this :
-- *** set prefs ****
tell application "AppleWorks 6"
      activate
      set oldPrefs to its preferences
      copy oldPrefs to tPrefs
      tell tPrefs
            set old version warning to false --doesn't show the old version warning alert
            set converted file suffix to true -- append “[v6.0]” to documents converted from older formats
            set locked file warning to false
            set paint reduction warning to false
      end tell
      set preferences to tPrefs
end tell
-- *** end set prefs ****
--**** your script, example ***
set tfiles to choose file with multiple selections allowed
tell application "AppleWorks 6"
      repeat with i in tfiles
            open i
            tell front document
                  -- do something
            end tell
      end repeat
end tell
--**** end your script ***
-- *** reset prefs ****
tell application "AppleWorks 6" to set preferences to oldPrefs
