Existing Alias in Max

I have an Agilent 34401A that is USB. I assigned it an alias in MAX. When we swapped instrument for calibration, max found the new USB address. But when I go to add the alias in MAX I get an error saying "Alias exist" and MAX will not save the configuration.
I can't find where the existing alias is to delete it. How do I delete it? I have attached the MAX report.

How to change the Existing alias with new alias name...MAXL SCRIPT

HI Experts
I need to change alias name of the existing member with new alias name.
please send me maxl code to change the alias name .
My thought is
1) Old alias should be replaced with new alias name .
2)There is one account that should be rolled out to another parent..these parents are already exsist
3) I need a MAXL Script to change the new alias name .
please suggest ASAP.
Thanks

John
I heard that we can replace existing alias name with new alias thru MAXL
i.e replace alias name XXXX member with YYYY ;
please correct me if iam wrong ,might be Maxl command is wrong but this is the idea.
Thanks

How to ask the I2C device alias name from the MAX

Hi,
How can I ask the I2C device alias name which MAX uses in Labview? If the VISA Alias on My System is for example I2C in MAX, I need to ask it in Labview and write it then to Device Reference In input of a I2C vi.
BR,
Jick

Here is a picture which should clarify the problem a bit more.
As you can see I use "I2C2" as an alias in MAX and I need somehow query that alias in Labview and write it to the device reference in input node. How?

MAX alias

Just a small query.
Why is it that we need to have an alias for a MAX function to fetch the data
query = "SELECT MAX(changeLogID) AS CID " +
            "FROM ChangeLog " +
            "WHERE beforeUpdate like '%Status:Active%' " +
            "AND beforeUpdate like '%labID:" + labID + "%'";
stmt = conn.createStatement();
rs = stmt.executeQuery(query);
while(rs.next())
       System.out.println(rs.getInt("CID"));
}The above code works fine as I have an alias for MAX. However, the below code throws an error
query = "SELECT MAX(changeLogID) " +
            "FROM ChangeLog " +
            "WHERE beforeUpdate like '%Status:Active%' " +
            "AND beforeUpdate like '%labID:" + labID + "%'";
stmt = conn.createStatement();
rs = stmt.executeQuery(query);
while(rs.next())
       System.out.println(rs.getInt("changeLogID"));

Alias won't stay assigned in MAX

Several years ago, I developed my own NI-VISA driver for a USB spectrometer. On Windows XP, they worked great - I could plug multiple spectrometers into the system, assign each one an alias in MAX, and then acquire data from whichever spectrometer I wanted. I could even unplug a spectrometer, and plug it into a different USB port and automagically the alias would follow it.
Then came Windows 7. Suddenly (with no code changes or changes to the driver), if the spectrometer was assigned an alias, then it ALWAYS had to be plugged back into the same USB port or the alias would not follow it. The alias would still be in MAX, but the spectrometer would be on another port. It was as if the alias wasn't just linked to the device, but the specific USB port as well. I'd have to manually delete the old alias and reassign it to the "new" spectrometer & port. Annoying, but not the end of the world.
But then it got really bad... Due to a recent engineering change that moved the spectrometer further away from the PC, even a 15ft USB cable isn't long enough. I have to connect my spectrometer to the PC using a Rose USB extender (USB-to-Ethernet-to-USB). Even though I never physically unplug the spectrometer, every time the power is cycled on the PC I have to manually reassign the alias.
This is a major issue for my application. I'm at the point where I'm thinking of giving up aliases entirely and just having to search for spectrometers based on serial numbers. But if we have to swap out a spectrometer in the field, we'd have to update a serial number config file or something equally ugly. Can anyone suggest a way I might be able to make the alias behave more like it did under windows XP? Or suggest another more robust solution?
Thanks,
JasonP

Hi Brice,
If you look at the attached image file, you can see the problem. The entries I've circled represent the same physical device. You can see that the serial number assigned to the device has changed from "NI-USB-30002" to "NI-USB-40002". If I leave the spectrometer plugged directly into a PC, I can reboot it without issue. But if I unplug it, or if it is connected to the PC through an ethernet-based USB extender, then the reboot changes the serial number as shown. And of course, trying to access the device using the alias will fail.
In my application, I might have as many as six spectrometers connected to the same PC. If I can't use aliases, I'll have to connect with each spectrometer, query it for it's internal serial number, and match it against an configuration table. I really was hoping to avoid that if at all possible.
Thanks,
JasonP
PS: I can't find the exact documentation for the extender we have, but the one shown in the attached PDF is very similar.

Does importing MAX config settings file replace or append the existing MAX entries?

Hi,
Does importing a .nce file into max replace the existing config of max with the imported config, or does importing add the new MAX items to the existing MAX items (so that both the "old" and "newly imported" config can be used.
Solved!
Go to Solution.

Either or both! (sometimes neither)
in the import wizard you can select which items to import and what to do about items that conflict or exist with different information. (NI really did a nice job - for NI devices!) for some things (like Pickering VXI devices) you can't import the MAX settings.

Using MAX vs Teststand for Switching

Can anyone explain whats going on here??
I went into MAX and gave all my ni switches ( MUX) aliases. This is under channel/exclusions tab. Under the Schematics tab is a column named route groups. I can give my relay connection ( like close relay 2) an alias here..like "Close Relay 2". If I click on relay 2 in the schematic it shows a connection between ch2 and com. Fine. Now when I go into Teststand >Properties TAb>switching>enable switching...I have the "Operation" "Connect". Is this redundant?? I already connected it when I called it. If its because Teststand doesn't know what I want when I call that particular alias will it "Disconnect" when I select Disconnect from the drop down??
Would you suggest I leave ALL my relays open in MAX and just "Connect" "Disconnect " them in Teststand??
Can you suggest what the other options should be if:
I want to connect 1 or more relays for this sequence, do some testing, then disconect those relays?? Is that Connection Liftetime?? So "Step"??
What is multimode and when/how do I use it??
Included a few screen caps
Thanks!

Hey Clint,
NI Switch Executive exists in both MAX and TestStand (and LabVIEW, etc). You can program individual routes in TestStand, or you can precreate complex route groups in MAX and then call those routes/route groups in TestStand. Say for example that you want to connect A to B, C to D, E to F, you can create a route group called "awesome channels" in MAX, then add the explicit connections to that route group (A to B, C to D, E to F). Now in TestStand you simply need to connect "awesome channels" and NI Switch Executive will do the rest.
While you can connect channels in MAX, the intent is that you create the route groups in MAX and then use those route groups in test stand (if for no other reason that TestStand is automated while MAX is not). Ultimately, you can use the SW however you'd like, but we intend for the runtime execution to be automated in teststand. Think of MAX as the debug/configuration environment.
Connection Lifetime is how long the relays should stay connected. For example, placing lifetime at "Step" means that as soon as that particular TestStand step completes, the relays will disconnect.
Multiconnect mode is the concept that a relay can be connected more than once in software. As long as the connect count is 0, the relay is open. If the relay count is greater than 0, then the relay is closed. Say, for example, that you have two different tests that can run simultaneously and they share the same relay. Specifically, test 1 requires relays A and B, while test 2 requires relays B and C. If you're able to perform both tests simultaneously (a function of your DUT), then when you connect test 1 and 2 simultaneously, relays A and C will both have a connect count of 1 (they've been connected once), but relay B will have a connect count of 2. Thus, when test 2 finishes and disconnects its associated relays, test 1 could still be running; since relay B will have a connect count of 1 after test 2 'disconnects' relay B, relay B will still be closed and test 1 won't be interrupted. The concept takes a minute to wrap your head around, but ultimately it is quite powerful.
NI Switch Executive is a very powerful program. Once you've played around with it for a bit, it is intuitively easy, but there is a higher rampup curve versus our other switch programming software (NI-Switch, NI-DAQmx, etc). NI Switch Executive is particularly well suited for TestStand.
Let us know if you have any other questions or if my answers aren't clear. Have a great day!

Unable to create Alias in 11g

Hi
I have one product table.
i am trying to create Alias on Product table. In physical layer i was right clicked on Product table. It shows all options( like New object, Update row count, view data.......etc)
when i am moving cursor on New object it doesn't showing any options.
Is any differeces in 11g. how can i create alias in 11g
Thanks

No. you should be able to create alias table. please verify if you are trying to create alias on topn of existing alis table that you cant. otherwise restart services and try again.
Thanks

Another MAX() function question...

Help was provided earlier for a question I had regarding use of the MAX function... This also pertains to that. I have two tables, employee and movie. I want to find the name of the employee who has entered the most amount of movies into our database. The query I have come up with so far (it's a little messy) is:
SQL> select firstname, max(m) from (select firstname, count(enteredby) m from em
ployee, movie where enteredby = id group by firstname) group by firstname;
FIRSTNAME MAX(M)
Peter 6
Swanson 5
Kevin 7
Beverly 3
So I have this table returned, now in this case I want to be able to select from this subquery the first name "Kevin", since he has entered in the most movies. In my head this seems so easy, "Grab the firstname of the person whose max(m) is the largest", but I am just having trouble getting this thought translated into a proper query!

You can always do
SELECT firstname
FROM (SELECT firstname, RANK() OVER (ORDER BY max_m) rnk
          FROM (<<your query>>))
WHERE rnk = 1Note that you'll need to alias the MAX(m) result first. You could also do
SELECT firstname
FROM (
SELECT firstname, RANK() OVER( ORDER BY cnt) rnk
FROM (SELECT firstname, COUNT(enteredby) cnt
          FROM employee e, movie m
        WHERE enteredby = id
        GROUP BY firstname)
WHERE rnk = 1From a style standpoint, I would suggest that you get in the habit of aliasing your tables in your FROM clause and putting that alias on every column name to make it clear which table a particular column was selected from.
I would also suggest that you come up with a column naming convention that caused the same value to be named the same (or similar) thing in different tables. Joining an ID column from one table to an ENTEREDBY, for example, would be a non-obvious bit of logic. It probably makes more sense to have an EMPLOYEE_ID and an ENTERED_EMPLOYEE_ID column.

MAX Reports-Initialization Error, Editing Components missing?

Using a NI PXI-1042Q and an 4472B Daq card to capture data. Running LabVIEW 8.2 on a Windows XP system. The program controls an MID7604 which controls a motor. Using a program that was written and is now an executable. To run the program minor file related inputs are required, the motor moves to calibrate its' position, then a test piece is requested to be adjusted. After the adjustment, file request information is acknowledged (location for data to be placed is ok'd).
After pressing OK, the following error message is generated:
[ ERROR-200428 occurred at DAQmx Start Task.vi, Possible reasons: Value passed to the Task/Channels In control is invalid. The value must refer to a valid task or valid virtual channels, Then it identifies the Task Name: __________.]
This of course refers to the Task/Channels IN input of the DAQmx Start Task.vi, which points to the task that was setup, not being setup properly or not there. In our case, it was there and has somehow been removed.
When going to MAX and trying to setup a new Task: Data Neighborhood --> Right Click --> Create New NI DAQmx Task,
the following message is generated:
!INITIALIZATION ERROR
Some components required for editing are missing. Please contact National Instruments for more information.
We have already viewed the NI-DAQmx Error-200428 message, and also tried the "How Do I Recover From MAX Database Corruption?" procedure, no change.
Please respond. Thanks.

Typically with an executable you only have the run-time versions and I don't think you can create a task with just the run-time. Somehow the hardware configuration has been corrupted. If you can find the original .nce file that was used on the development system, you can just import that I believe. Otherwise, you may have to install full versions of DAQmx.
The reliance of existing tasks in MAX is one reason that I avoid them and create everything in the LabVIEW program. Just one thing to keep in mind.

MAIL will not allow iCloud alias to receive mail

I am not a novice. I have been on iCloud (sadly) since July 2011. Today I tried to activate an email alias which was transferred into iCloud. It's valid and has been for years, but not activate since I migrated to iCloud.
Every time I set up the existing alias in MAIL I get the error "invalid incoming mail server." I have used the Apple recomendation to use imap.mail.me.com. When it comes time to exist ACCOUNT under Mail PREFERENCES, it will never SAVE changes as the incomding mail server information is grayed out and goes back to "example" and is not accessible.
I have also entered p99-imap.mail.me.com with the same result.
Two hours of going to icloud.com or managing my apple id online have brought exactly the same result. Although the alias shows as activated under icloud.com and although it is accepted by MAIL, the message is always the same (invalid incoming mail server) and the account change can never be saved in MAIL.
XXX
I have a business with MobileMe accounts and we are going to be forced to migrate to icloud in a few months. I have nightmares about it alraedy.
Since Apple doesn't give a good cr*p about this, I humbly ask if there is anyone who really knows what is going wrong and how to work around it?
Again: I migrated to icloud with my apple id in July 2011. MAIL will NOT set up my icloud alias as it always grays out the incoming mail server and returns the error "invalid incoming mail server" and will not even allow me the save the information.
Please help.
Thank you.

Hi Roger
Thank you for your suggestions.
I already have an ALIAS set up and receiving emails in my main INBOX under the alias name. It is a MobileMe alias from my separate business mac account. It has worked as a separate "account" under MAIL for 10 years. It is an ALIAS, not a main identity mac account. The System Preference panel is ACCOUNTS, not aliases, so I use the word "account" when I speak of setting up a new inbox with a different name and password whether that is an iCloud alias or a gmail account.
We may be talking about the same thing but I'm not using a word you use. I am allowed 3 icloud mail aliases. I am allowed 5 mail aliases under my business mac account. On my mac MAIL I already have three separate "accounts" or inboxes: (1) my private mac ID account (2) my business MAC account (3) an alias from my business account. All three have different passwords. None of the three gets emails sent the other two "accounts."
Maybe I just don't get "icloud." I certainly got "MobileMe" in the past. The alias that is currently working as a separate "account" or "identity" under MAIL is proof of that.
I am going to delete the "alias account" from MAIL and call it a day. For me, iCloud is commensurate with Windows ME in the history of computing: a stupid change that resulted in nothing but aggravation for everybody who was dumb enough to sign up for it. I won't be signing up for the next "big thing" from Apple. I'm sure there are tens of thousands of other users who feel equally "used" by Apple on this.
I'm marking the question ANSWERED and closing the thread. iCloud is iCrap and nothing I've experienced with it in six months has changed that opion and the fact that you can get a gmail account operating in MAIL in 2 minutes but you can't get an iCloud email alias working in five hours is just more fuel on that bonfire.
Thank you again for your couresty and your time. I doubt if my business account, which has to be downgraded to iCloud in a few months, will function at first and I doubt if the 10-year-old alias on that account will continue to function in MAIL.
Mike

Alias to user directory on remote computer

Hi there,
I was wondering if it is possible to create an alias to a folder in the user directory which can then be ported to another computer and point to the same directory for another user.
I read something about the usage of the symbol '~' to point directly to the user directory.
How can I create an alias that points to '~/Library/Screen Savers/' where the '~' is the 'home/user/'?
Can anybody help me out on this?
Thanks in advance...

Thank you so far. But it's still not quite what I need.
I'll make an example. I made a screensaver that consists of some files. In order to work, all files have to be placed into the /User/Library/Screensavers/ directory. Now, I want to give these files burnt on a cd to a friend that doesn't have much knowledge on macs but runs one. The easiest way for that friend would be, if he would insert the cd, see the finder window with the files and an alias in it. All he would have to do would be to drop the files on that alias and they would be copied to the /User/Library/Screensavers/ directory of his mac.
Much like the aliases that you can find on thirdparty apps that are inside a .dmg file and all you have to do to install them is to drag them onto the applications alias that is also in the .dmg
I read somewhere that the symbol ∼ refers to the default users directory, but I can't figure out how to change an existing alias and insert that symbol.
I hope it is clear now what I'm trying to do. Thanks in advance...

Change MobileMe-alias email to AppleID

I've switched from MobileMe to iCloud some weeks ago and now I have a question concerning to alias-email-adresses.
In MobileMe I have used some alias-email-adresses for different things (surfing in the internet, communities etc.) and one of them is used by my wife.
With iCloud it's possible to share and edit iCal-calendar and this is great; so my wife and I could use different accounts now.
But the main question is:
Is it possible to create a new AppleID from an existing alias-email?

You cannot change an alias to anything else - it remains tied to the account which created it, even after you've deleted it.
