The first step with multiplexer
Hello everyone,
This is the first time, we will use und multiplexer, we don't know what we can do. I have a practical training at the University, and we should use multiplexer with labveiw 2012
Description:
-in this project, we have a program, this programm for signal measurement and this programm worked same will. Our role in this project, we will extend this Programm, that we will use multiplexer with 20 entrance and exit.
-We go to conenct 20 devices in a laptop computer to measure the parallel of 20 devices (signals). the time between each Signal on the output side should be of 5 ms.
My question is: what we don first after the connection of devices-20? We should install the driver? What function do stupid to write question? should we write RS232 function "funktion write, read, open serial... etc." or it takes not just with multiplexer? ' " I know, it's a stupid question, but I'm sorry we don't know what we can do, and as I say it is the first practical training.
Thank you very much
Hello
I use a multiplexer to connect several devices to measure the values. I use the multiplexer "USB-ERB-24", so I can measure 24 devices at the same time. I already ordered the multiplexer, but so far it is not getting... So I thought to prepare the software.
My question is, I've programmed the multiplexer blindly and would like you checked my program, if it's just
On the picture you can see that I used "wait" and "timing" funktion release time because should probably be 50 ms... This means that the data is read from a device, and after 50ms must read data from the next connected device... etc? Here, I have not defined a fixed value for the time to release... maybe I have an error and my multiplexer will made to automatically release time because in the Datenscheet stand at the release time which is 50 ms? I don't know if the the mux do this automatically an i donot need to use here "Wait" or function "sync"?
The second part of the program is: I will not use a single multiplexer but two multiplexers. So I can measure 47 instead of 24 aircraft. In the last relay (nr. 24 entries) of the multiplexer1 connect the second multiplexer. for this purpose, it was necessary to extend my program... See image 2 in ULX 'write.vi', I joined to the smallest feature... So it will be tested with data on how many devices are connected, in other words, he checked with the creation of the matrix whose values are True (true value = connected device) and real values will be in a new table added, after generating the new table, it will determine the size of the array (the new table size) If the size of the table = 24 ==> the second mutiplexcer is connected and the waiting time (time releasing = 24 * output wait time). It is true that I have do the extension in "write data"? Do you think that so far is everything is ok, or not?
Thank you for your help

Satellite A300-1RZ - stucks Windows 7 upgrade on the first step of the installation
Hi all
I'm Italian, I an A300 Satellite with Vista Home Premium I paid 30 euros for the free upgrade to Windows 7, which reached my House yesterday. I got 2 DVD:
-1 to 'prepare' my phone: * TOSHIBA UPGRADE DVD *.
-1 upgrade operating system: * WINDOWS 7 HOME PREMIUM UPGRADE DVD *.+ The first step: + use the first DVD: all right, "the system is ready to install Windows 7, insert the second dvd. When I insert the other, I accept the license and after that, the first step of the installation: * "check system compatibility."
* These steps is my problem.*I reworded more than 10 times the praxis but it blocks at this stage, I left the laptop at this stage, throughout the night, but today morning she was always there, no progress, it is clear that there is a problem, but I do not understand if it depends on my cell phone or on the DVD.
I tried to boot the laptop with Windows 7 DVD inside, start the system by the DVD, but it ask me to format the partition where are the files of vista and is not an upgrade. I bought an upgrade just do not remove previous programs and do not format the first partition of the drive of my laptop.
How do, which can, I turn to?
Does anyone have the same problem?
Does anyone know to escape?thanx 4 your answers

I just purchased creative cloud. What is the first step I should take?
I just purchased creative cloud. What is the first step I should take?
I'm unable to download the apps and I don't know why. I thought it had something to do with me having the prior consent of the trial, so I advanced and deleted. And I can not even download applications. Am I missing a specific step in all of this? I was under the assumption that when I bought the creative cloud, it would be a kind of command prompt to install the program (the way adobe works normally) then I would be able to install applications separately.
Hi Poe7,
Welcome to the community & thank you for being the Member of creative cloud!
The first thing is to download Creative cloud desktop application that will help you to download all the available applications, go to https://creative.adobe.com/products/creative-cloud and download it.
One time downloaded, launch it and select any product to start the download/installation of the app.
Thank you!

I stupidly downloaded Acrobat DC and now I can no longer save or print my attachments without buying a subscription which I don't want. I want to uninstall DC and reinstall XI. The first step said to go to the creative cloud, I did not. Thank you.
Hi sharonj83072502,
Are you referring to DC Acrobat or Acrobat Reader DC.
Acrobat Reader DC is a free application & Acrobat DC is a purchased app.
To uninstall the application, do so simply in the Applications folder in the trash folder.
Restart your Mac & if you want to install Reader 11, you can download it using this link https://get.adobe.com/reader/enterprise/ , else if it were XI Acrobat, you can download using this link Download Adobe Acrobat products. Standard, Pro | DC, XI, X
Kind regards

My first steps with RESTapi of VEEAM
Hello
I started to play a bit with the RESTapi of VEEAM Ent. Server.
But in question is not directed to the Application. It's more about the handling of a RESTapi results.
My Script:
var PostResponse = BRHost.createRequest("POST", "/sessionMngr/?v=v1_1", null).execute(); var TenantsResponse = BRHost.createRequest("GET", "/cloud/tenants", null).execute(); //System.log("Tenants " + TenantsResponse.contentAsString); var XMLFile = XMLManager.fromString(TenantsResponse.contentAsString); var XMLelement = XMLFile.documentElement.getElementsByTagName("Ref"); for(i=0;i<XMLelement.getLength();i++){ var Tenant = XMLelement.item(i).getAttribute("Name") if ( Tenant == TenantName){ var UIDTenantFull = XMLelement.item(i).getAttribute("UID") var UIDTenant = UIDTenantFull.slice(-36) var RessourceResponse = BRHost.createRequest("GET", "/cloud/tenants/" + UIDTenant + "/resources", null).execute(); //System.log("Tenant Ressources: " + VMResponse.contentAsString); //System.log("Content as string: " + RessourceResponse.contentAsString); var RESdoc = XMLManager.fromString(RessourceResponse.contentAsString); var RESlist = RESdoc.documentElement.getElementsByTagName("CloudTenantResource"); System.error(RESlist.getLength()); for(j=0;j < RESlist.getLength();j++){ var RessourceID = RESlist.item(j).getAttribute("Id"); System.log("Ressource ID: " + RessourceID); var RessourceResponseDetail = BRHost.createRequest("GET", "/cloud/tenants/" + UIDTenant + "/resources/" + RessourceID, null).execute(); System.log("RessourceResponseDetail: " + RessourceResponseDetail.contentAsString); } } }
An example output:

My result back look exactly like that.
Here is the Question how to process the result.
First I want to try to extract everything "" < RepositoryQuota >' in the fields in a table. "
What is the best way to do it?
Hello
The best way to consume the XML in Javascript is using E4X. Here is a code example:
default xml namespace = "http://www.veeam.com/ent/v1.0"; var doc = new XML(RessourceResponseDetail.contentAsString); System.log(doc.Links.Link[1].@Type); System.log(doc.RepositoryQuota.RepositoryUid);
- On the first line, we declare the default namespace (xmlns in your XML attribute)
- On the second line, we load the XML content in a Javascript variable named doc, that gives you a hierarchical XML data access
- Third and fourth line show how access by index the array element (link [1] means the second element of link), attributes (@Type means the value of the Type attribute) and elements (RepositoryQuota and RepositoryUid).

Return the first line with a non-null value in a column
Hey there, gurus. Can someone give me a hand with this?
I have a table with six columns: Class_ID, Course_ID, start_date, Last_Name, First_Name, company. When our students take a class and will fill in an evaluation form, they fill in the Class_ID Last_Name First_Name, and Company. The Course_ID and Start_Date are filled automatically based on the Class_ID.
I am trying to generate a report that contains Class_ID, Course_ID and Start_Date, PLUS the value of the first not null in the column of company for a combination given to the three first columns. Here is my SQL that does not quite do the trick:
Select distinct c.class_id, c.course_id, c.start_date, p.company
class c, person p, student s
where substr (c.course_id, 1, 3) = "OBI".
and c.start_date > = SYSDATE-30
and c.class_id = s.class_id
and s.pid = p.pid
order start_date, company, class_id, course_id
At present, if in a given class, a student entered "CCCC" under the name of the company and another entry "Collin Co Comm Coll" and another between "Collin College", I would get three rows of this class when you use the SQL above. I want just one line. I don't really like which company names gets selected - one of them will be great for our needs. I just need to see a line for each class_id and single value that some students entered the area of the company. And I guess I have to say that if no student fills in the name of the company I need to see the value null, because I need to see the line no matter what.
Looks like some sort of funky outer join or a coalesce, but it is beyond my ability to understand.
Now I get this:
During class 1234 SQL271 Date 22/07/2013 company XYZ Inc.
Made up of class 1234 SQL271 Date 22/07/2013 company XYZ
1234 SQL271 Date 22/07/2013 company XYZ, class
What I want:
Class 1234 SQL271 22/07/2013 Date course XYZ Inc. or one of the other 2
Thanks in advance!select c.class_id, c.course_id, c.start_date, max(p.company) company from class c, person p, student s where substr(c.course_id,1,3) = 'OBI' and c.start_date >= SYSDATE-30 and c.class_id = s.class_id and s.pid = p.pid group by c.class_id, c.course_id, c.start_date order by class_id, start_date, course_id

Pulling on the first line with a value of repetition
Hello
We use the Oracle 11.1.
We have a table of postal codes.
We have several lines for each zip code because we have different areas that use the same zip code.
We want to reduce the lines of a line by zip code. But they said use they want to keep the fields that differ (neighborhood of the exodus).
Then they said "Just take the first value of each."
This code reduces the postcodes of a line by postal code, but as you can see I replaced the field with the name of the field values.
How should I take either one record per postal code with the first value in these fields orSELECT distinct ZIPCODE, CITY, STATE, COUNTY, AREACODE, 'CITYTYPE', CITYALIASABBREVIATION, 'CITYALIASNAME', LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE, MULTICOUNTY, STATEFIPS, 'CITYSTATEKEY', 'CITYALIASCODE', 'PRIMARYRECORD', CITYMIXEDCASE, 'CITYALIASMIXEDCASE', STATEANSI, COUNTYANSI FROM zip_code GROUP BY ZIPCODE, CITY, STATE, COUNTY, AREACODE, CITYTYPE, CITYALIASABBREVIATION, LATITUDE, LONGITUDE, TIMEZONE, ELEVATION, COUNTYFIPS, DAYLIGHTSAVING, PREFERREDLASTLINEKEY, CLASSIFICATIONCODE, MULTICOUNTY, STATEFIPS, CITYALIASCODE, PRIMARYRECORD, CITYMIXEDCASE, STATEANSI, COUNTYANSI order by zipcode;
How should I take the first record for each zip code?
either way works for me.
Thank youHello
This is called a Query Top - N , and this is a way to do it:
WITH got_r_num AS ( SELECT z.* , ROW_NUMBER () OVER ( PARTITION BY zipcode ORDER BY city , ... -- add tie-breakers here ) AS r_num FROM zip_code ) SELECT * -- or list all columns except r_num FROM got_r_num WHERE r_num = 1 ;
You can simply use MIN or MAX on the columns, as the line with the name of the minimum city do not lowest have area code or the longitude. The above method preserves the first line of each zip code intact, where the 'first': the first in order of aphabetic by the name of the city. If it is not unique, then you may want breakage to the analytical ORDER BY clause.
If you are deleting rows, you can use this in a NOT IN subquery. If you copy lines to a new table, you can use the query above in an INSERT statement.

You can use the rank or rownumber function...If I understand the problem, you don't want to use RANK in this particular case. When there is equality, GRADE will assign 1 to all the contenders. I think the whole point of this thread is that you exactly want a #1 in each zip code, which is what ROW_NUMBER, but not RANK, guarantees.

Struggeling with the first steps on php vcloud sdk

Thanks a lot for your help!

PS: well, php works fine on this machine
For your argument if you used "MyServer" or "https://myserver"? It should also, if you look at the source code of login.php, you will notice that it accepts only 3 args command line: server, user and passwd. The host/peer SSL are already set to false by default, so you don't need to call it from the command line because it is not a valid argument and is simply ignored. I think that the error is due to missing "https://".
Also in the future, you can post in the dedicated vCloud SDK for PHP forum - http://communities.vmware.com/community/vmtn/developer/forums/vcloudsdkphp if you have any future questions regarding the PHP SDK

If restore work not and you do not have a Vista DVD from Microsoft, do a repair disc to do a Startup Repair:
Download the ISO on the link provided and make a record of repair time it starts.
Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.
At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu.
When you have changed that, insert the Bootable disk you did in the drive and reboot.
