How is numeric data received with UDP interpretted?

A device sends numeric data with the UDP protocol and the transmitted data is simply a sequence of numbers.
Example:
Numbers 500, 501 and 502 in 16 bit big-endian representation (0x01F4, 0x01F5, 0x01F6) results in the data
0x01 0xF4 0x01 0xF5 0x01 0xF6 (6 bytes)
How does the LabView UDP Read.vi (ver. 5.1) interpret this data when displaying it in string format? Does it return the string "01F401F501F6" or does it return the six characters that have the ASCII values
0x01 (1)
0xF4 (244)
0x01 (1)
0xF5 (245)
0x01 (1)
0xF6 (246)
making the string "☺¶☺§☺÷" ?

It does not "interpret" anything, you'll get the string with the six raw bytes. It is up to you to cast it to the right data type.
Use "type cast" to interpret it as the 16bit, see attached image for an example (I assumed U16).
(Note that you can of course set the string to display the hex code for clarity, especially if you expect unprintable ASCII codes. To do so, right click on it and select hex codes. This is only cosmetic).

No data received with wget command on Solaris 10

Dear All,
When I use the 'ping' command is can ping to the server normally but when I try to use the 'wget' command to retrieve data from Server is cannot get anything.
I got the error message as bellow
./wget no-check-certificate private-key=/cert/data.pem --certificate=/cert/data.crt "https://server1.com.kh/data/?action=datano;datano=aaaa" -O-

What do you actually want to do?
1. connect to a https url and ignore whether the returned certificate is valid or not?
./wget --no-check-certificate "https://server1.com.kh/data/?action=datano;datano=aaaa"
2. connect to https url and only connect if the returned certificate is valid and/or in your truststore?
./wget --ca-directory=/cert "https://server1.com.kh/data/?action=datano;datano=aaaa"
3. connect to https url and provide your own client certificate to authenticate to server?
./wget private-key=/cert/data.pem certificate=/cert/data.crt "https://server1.com.kh/data/?action=datano;datano=aaaa"

How to transform data received from file adapter

hi',
I am reading the data from XML file using file adapter, now I want to write the same contents which I have read from this file to a different/new XML file, the issue is I am unable to perform a transform here, when I use a transform with source element as the output of the file read and target as the input to the new file it is writing an empty file,
I have checked the audit trail which showsme that the transform is empty.
please tell me how can I transform the element which I have received from one file to make them as input to next file
thanks
Yatan

thanks James for input, this is my XML and XSD files
XML file:

I am reading XML file, I will describe my process.
1.) File adapter>read operation ---> receive activity
2.) Transform > source(receive input variable) <--->target(Invoke input variable)
3.) File adapter > write operation ---> invoke activity
Now when I am deploying this process it is sucessfully completing and able to read the file.
when I check the audit trail receive activity shows XML data but when I check the transform it
shows empty as below, however the write activity is performed which creates a xml file but no values in the elements

How to delete data-records with BI-planning in BEx?

Hi folks, masters and gurus,
we just upgraded some of our functions from BPS to BI-Planning.
Only one thing I could not resolve up to now:
In BPS (web based) it was easily possible to delete data-records by choosing a radio-button beside the data-entry-field and click the "delete"-button (a red "-") on the top.
When I tried to find a delete-function in RSPLAN now I only found one that deletes the data, but not the record itself.
Does anyone know how to build a function that I can use to delete data-records?
Thx in advance for your help,
Thomas

Oh yes ... it´s not necessary as it is easily possible to supress lines with only 0 in it with
query-properties / rows/coloumns / supressing Zero / activ ...

How to create date variable with interval in VC

Hi Everyone,
I have 2 questions:
My scenario:
I am using a BI 7.0 Query which is having some variables. I want the same variables to be displayed in the VC output.
Question 1:
I know that how to bring these variables in variable screen, but when we use these queries, dont the variables in the variable screen automatically ask for the input?
I tried it but it is not happening automatically.
There are 2 inputs for queries with variables, i tried using both, but it is not working properly. Can any one tell me is it possible.
Question 2:
In this variable screen, I have to select date with interval format. but i dont know how to use variable with interval. ( Date with interval format).
I hope some one might have come across the same scenario .. If so please share with the solution me ..
Regards,
Chan

Ok .. Let me be very clear .. I think I confused you.
As you mentioned I have done every thing in query level.
I have created a query with a variable which is an interval based variable(date).
When I execute the query it asks for the dates to display the inbetween data.
I gave the inputs and the data is displayed properly.( So far what I have mentioned is all in Query designer).
In VC, I have used this query and it is having two ports named INPUT and VARIABLE. I know that I need to give input in variables. I selected the calander month variable from the list to display. After this I deployed the model. In the output screen the table is displayed and 1 text box is also available for the date input. I know that here I have to give date with same format as in Query designer output. I tried so many ways to give input by even selecting some other options like date picker but it is giving the following error - Variable expects interval values; enter an interval.
The date format which I m using in Query is "MM.YYYY" and I m using the same format in VC too.
Now I hope that u can understand better.
I want to know is there any other way through which this can enter interval value or what mistake I m doing in the above explained scenario?
Regards,
Chan

How to use data sets with smart objects?

Hi,
I have a psd of some mock-up boxes, and I want to apply different text to multiple versions. The solution here: http://helpx.adobe.com/photoshop/using/creating-data-driven-graphics.html is good, but doesn't seem to work with smart objects?
The file that I have has the box label as a smart object (which opens as a psb). How could I apply a data set to that, and have it pump out multiple jpegs?
If I apply the data set to the psb layers, then go back to the main image, I cannot export the whole complete picture anymore.
Thanks!

What database and connection type are you using? Are you connecting the report directly to the database, or trying to assign the datasource to object data?
It sounds like you might be trying to use a linked list, collection or other C# construct to pass your data in. This currently isn't supported by the Crystal Reports SDK. You can use a DataSet or a DataTable, and possibly also an IDataReader depending on which version of Crystal Reports you're referencing in your project. Of course you can also connect directly to the database, even if the database isn't on the same machine as the application.
The way to show master records with detail information is through the use of subreports and linked subreport parameters. Linked subreports take their parameter value from a record in the main report, so that only the data appropriate to that master record is displayed. The guys over in the [report design|SAP Crystal Reports; forum can help you out with this if you have questions on the specifics.

How is ATG-Data utilized with weblogic compared to Jboss?

Greetings,
I have expertise with ATG on Jboss and am new to WebLogic. So far so good but I have a few questions that I have not been able to answer on my own.
How does WebLogic handle ATG-Data? I have set the server start options within config.xml for each instance - the java options for module list, server name, atg data directory location and memory requirements as I normally do with the run.conf for jboss. However, nothing gets populated in the ATG-Data directory when starting up the servers. On set runassembler with standalone and liveconfig on as well. (understanding that i can use pack and standalone together with weblogic).
Any ideas what I could be missing?
Thanks!
-Kip

OK I got ATG-Data directory working as I was expecting. Seems CIM was my hindrance. I scrapped the managed servers that CIM created for me and recreated them from admin console and then redeployed the -standalone ears using nostage deployment plan.
With this I now get ATG-Data directory where I wanted it: /opt/Oracle/ATG-Data/servers/store-a/localconfig (last entry for config layer in the store-a.out log)
This ATG-Data directory is configured in the domains config.xml for server-start arguments under the managed server group.
-Xms1280m -Xmx1280m -Xmn256m -XX:PermSize=512m -Datg.dynamo.data-dir=/opt/Oracle/ATG-Data -Datg.dynamo.server.name=store-a
This is progress!
However, the module list shows all modules that were applied during runassembler for that atg server in the log - I am unable to override the module startup list with -Datg.dynamo.modules= within server start arguments.
The reason I want to override the list is because I prefer to use the same ATGProduction ear for lock manager and procedit servers without requirement them to load all the modules that were assembled in the ear.
I appreciate any tips or suggestions for best practices!
Thanks!

How to connect Data Services with microsoft SQL/ Steps

Hi Aditya,
You can use a datastore of type ODBC using the IBM Client Access driver or the DataDirect driver that comes packaged with Data Services. There is a sticky thread on downloading the DataDirect driver. There is also another option to connect with the Attunity driver for the AS400. You cannot use the DB2 UDB drivers to connect to the AS400 V6R1.

How to recover data lost with Boot Camp

I was removing my boot camp partition when in the middle of it boot camp crashed. I went back into boot camp to check if the option to uninstall windows was still there, but it wasn't. I went to about this mac etc. and the storage didn't show my windows 7 partition but the data from the windows 7 partition was gone and My macintosh HD was missing the storage. Any Ideas on how to fix it? Sorry if my question doesn't make sense.

I guess everyone has their own idea of what is easy. A backup, reformat, restore to me is an utter PITA. Once you have free space, that free space is still not usable by Mac OS. You have to expand the Mac OS volume to use it. Sometimes this can fail because of the weird way Apple has chosen to sequence the partitions, with the Recovery HD Partition located after the Mac OS partition, making Recovery HD in between Mac OS and Free space. Apple's diskutil resizevolume command will move Recovery HD around as part of a resize. The basic command is:
diskutil resizevolume /dev/disk0s2 limits
That will show minimum, current and maximum resize limits. If current doesn't equal maximum, then free space has not been incorporated into the Mac OS volume. You can sometimes fix this with:
diskutil resizevolume /dev/disk0s2 R
That will expand the Mac OS volume to maximum size. If it fails then it's worth reconstructing the HFS+ catalog with:
fsck_hfs -r /dev/disk0s2
That command requires the file system be unmounted so you'll need to boot off another volume - Recovery HD is fine.
All of these are commands leverage features which the GUI doesn't offer access to.

There is a database toolkit for LabVIEW. I don't think it is a free download however. With the Data Manipulation toolkit, you can integrate with most databases that use the ODBC protocol.
If you don;t need anything fancy, you can write the values out to file using the write/read spreadsheet VIs. If the file is [COMMA] or [TAB] delimited, you can import it into your database with ease.
Another approach is to format you output to a text file as SQL, and import the records that way.
INSERT INTO TEMP_HUM_TBL (Temperature, Humidity, Txn_Date)
VALUES (30, 95, 'Dec-24-2013');

Hi,
You need to build the parfile commands first (using
server sysdate), and then pass the parfile to
Oracle:
touch /tmp/parfile.txt
Why bother with the 'touch'?
file=/anadbora13/Oracle_Backup/UIBS/dump/inter_UIBS_FM
_`date +%d%m%y_%T`.dmp >> /tmp/parfile.txt
Shouldn't that be 'echo file=.... > /tmp ....'
Why do you show the redirection to append into the temporary command file?
Now, execute the utility. . . .
expdp parfile=/tmp/parfile.txt

How to create Date relationship with Fact and DimDate on Tabular model?

I have two tables in SQL Server 2014 SSAS Tabular model.
DimDate(defined as data table) have date column (format is 1.7.2010 00:00:00) This table have been impoted from AdventureWorks.
FactSales have SalesDate column (format is 25.03.2015 18:08:05). This table have been imported from Excel. Colums is defined as date in Excel.
When I set Data Type as date in Tabular I get error:
"Datatype conversion failed for table...Value:'25.03.2015 18:08:05'"
I have tried to create calculated colums like =DATEVALUE([SalesDate]) and =DATE(YEAR([SalesDate]),MONTH([SalesDate]), DAY([SalesDate])), but getting error.
What should I do so that I can create relationship between Date column?
Kenny_I

Hi Kenny_l,
According to your description, you fail to convert the data type into date after creating calculated column with expression. Right?
In Analysis Services, the tabular will detect the source data type to determine which data type can be converted to. If you want to convert a data into date type, no matter this data is from database or a file, you must make sure this data can be recognized
as a date in SQL Server. In this scenario, the format '25.03.2015 18:08:05' can't be recognized as date even you apply DAX functions. So please change the format of the column in excel like "03.25.2015 18:08:05".
PS: For testing, you can create a temp table and insert sample text into a date column, because the date format in SQL Server depends on the location selection when installing.
After retrieving data from data source and all values within column are correct format, you can change the data type into Date, and select the format you expect.
If you have any question, please feel free to ask.
Best Regards,
Simon Hou
