How use TestStand to load a txt file ?

How to use TestStand to load a text file ?

Hi,
You will have to write a code module, in one of the supported languages, such LabVIEW, C, to do this function.
You could also use the PropertyLoader to load a variable or a step property, but the file has to be formatted in a certain way. The Reference Manual page D-6 will explain this.

How can I load a .TXT file into a dynamic text box?

I am sure that many people know how to load a .txt file into
a dynamic text box. But I do not. I want to be able to reference a
txt file from the server into the text box. So that when I change
the text file it changes in the flash movie without even editing
the flash file itself. Thank you.

I think this is the simplest way to go :)

How to get the loaded client sequence file path/name?

I added a step in Process model, and wanted to get currently loaded client sequence file name/path. I used the variable of "SequenceFile.Path" but then I realized what I would get is the process model file path, not loaded client sequence file path/name. How can I get loaded client sequence file path/name?
Thanks!
Jacky

I dont understand what you are trying to achieve. Can you provide more information.
If you are trying to dynamically load and run a client sequence file at run time you need to make a couple of calls to the TS API from inside the process model, Engine.GetSequenceFileEx to get a reference to your sequence identified by its pathname, and then Execution.ClientFile to tell the process model which sequence you want to run.

How to save in CSV or TXT file the Powershell script output?

Hi,
I am not sure how to expot this to csv/TXT file, should I use export-csv "c:\test.csv" ?
my code:
$site = Get-SPSite "http://tst.pg.com/sites/tsta"
Write-Output("`n" + $site.URL)
$myweb = $site.AllWebs | where {$_.url -eq $site.url}
Foreach ($list in $myweb.Lists)
if($list.BaseType -eq "DocumentLibrary")
Write-Output("")
Write-Output("Doc Library Name:" + $list.Title)
Write-Output($list.roleassignments | ft Member,RoleDefinitionBindings -auto)
}$site.dispose()

Hi there - If you just want to dump the output as a txt file, how about the following?
.\yourpowershell.ps1 > output.txt

Best Practice regarding using and implementing the pref.txt file

Hi All,
I would like to start a post regarding what is Best Practice in using and implementing the pref.txt file. We have reached a stage where we are about to go live with Discoverer Viewer, and I am interested to know what others have encountered or done to with their pref.txt file and viewer look and feel..
Have any of you been able to add additional lines into the file, please share ;-)
Look forward to your replies.
Lance

Hi Lance
Wow, what a question and the simple answer is - it depends. It depends on whether you want to do the query predictor, whether you want to increase the timeouts for users and lists of values, whether you want to have the Plus available items and Selected items panes displayed by default, and so on.
Typically, most organizations go with the defaults with the exception that you might want to consider turning off the query predictor. That predictor is usually a pain in the neck and most companies turn it off, thus increasing query performance.
Do you have a copy of my Discoverer 10g Handbook? If so, take a look at pages 785 to 799 where I discuss in detail all of the preferences and their impact.
I hope this helps
Best wishes

Using Flashvars to load external mp3 files

I am trying to find a very good step by step tutorial on using "Flashvars" to load external mp3 files, I have been searching on google and the many I have found fall short in some way or another. From what I have been able to gather, I have tried using the code in red (commented out), which works, and modify it to use "Flashvars". The code that works, the mp3 file is hard coded, but my goal is to use "Flashvars" which I am attempting to do in the code following the code in red. I am also including the html code. Any help will be greatly appreciated.
Thanks,

Ok waterlovinguy,
I went back to my original code, and I got things to work... I think my whole issue was with the HTML CODE. So I decided to use the "SWFObject generator". I had never used it before, frankly I had never heard of it until I started my searches on "Flashvars".
Thank you very much for all your assistance, PEACE,

How to retrieve IndividualStrings from a txt file using String Tokenizer.

hello can any one help me to retrieve the individual strings from a txt file using string tokenizer or some thing like that.
the data in my txt file looks like this way.
Data1;
abc; cder; efu; frg;
abc1; cder2; efu3; frg4;
Data2
sdfabc; sdfcder; hvhefu; fgfrg;
uhfhabc; gffjcder; yugefu; hhfufrg;
Data3
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
val1; val2; val3; val4; val5; val6;
i need to read the data as an individual strings and i need to pass those values to diffarent labels,the dat in Data3 i have to read those values and add to an table datamodel as 6 columns and rows depends on the data.
i try to retrieve data using buffered reader and inputstream reader,but only the way i am retrieving data as an big string of entire line ,i tried with stringtokenizer but some how i was failed to retrive the data in a way i want,any help would be appreciated.
Regards,

Hmmm... looks like the file format isn't even very consistent... why the semicolon after Data1 but not after Data2 or Data3??
Your algorithm is reading character-by-character, and most of the time it's easier to let a StringTokenizer or StreamTokenizer do the work of lexical analysis and let you focus on the parsing.
I am also going to assume your format is very rigid. E.g. section Data1 will ALWAYS come before section Data2, which will come before section Data3, etc... and you might even make the assumption there can never be a Data4, 5, 6, etc... (this is why its nice to have some exact specification, like a grammar, so you know exactly what is and is not allowed.) I will also assume that the section names will always be the same, namely "DataX" where X is a decimal digit.
I tend to like to use StreamTokenizer for this sort of thing, but the additional power and flexibility it gives comes at the price of a steeper learning curve (and it's a little buggy too). So I will ignore this class and focus on StringTokenizer.
I would suggest something like this general framework:
//make a BufferedReader up here...
do
String line = myBufferedReader.readLine();
if (line!=null && line.trim().length()>0)
line = line.trim();
//do some processing on the line
while (line!=null);So what processing to do inside the if statement?
Well, you can recognize the DataX lines easily enough - just do something like a line.startsWith("Data") and check that the last char is a digit... you can even ignore the digit if you know the sections come in a certain order (simplifying assumptions can simplify the code).
Once you figure out which section you're in, you can parse the succeeding lines appropriately. You might instantiate a StringTokenizer, i.e. StringTokenizer strtok = new StringTokenizer(line, ";, "); and then read out the tokens into some Collection, based on the section #. E.g.
strtok = new StringTokenizer(line, ";, ");
if (sectionNo==0)
//read the tokens into the Labels1 collection
else if (sectionNo==1)
//read the tokens into the Labels2 collection
else //sectionNo must be 2
//create a new line in your table model and populate it with the token values...
}I don't think the delimiters are necessary if you are using end-of-line's as delimiters (which is implicit in the fact that you are reading the text out line-by-line). So the original file format you listed looks fine (except you might want to get rid of that rogue semicolon).
Good luck.

How to load a txt file into a table

Hi,
I have a txt file
3 sample records:
25     fff     fff     2012-03-08 13:42:31.0     2012-03-15 14:58:31.0
26     ooo     ooo     null     null
27     ooo     ooo     2012-03-22 10:39:49.0     null
I have problems with the nulls:
my ctl is like that:
load data
append
into table table_name
fields terminated by '\t'
OPTIONALLY ENCLOSED BY '"' AND '"'
trailing nullcols
( ID CHAR(4000),
LITERAL CHAR(4000),
DESCRIPTION_WEB CHAR(4000),
FECHAALTA TIMESTAMP "YYYY-MM-DD HH24:MI:SS.FF1",
FECHAMODIFICACION TIMESTAMP "YYYY-MM-DD HH24:MI:SS.FF1"
I get the following error because of the null:
Record 2: Rejected - Error on table MKT_WEB, column FECHAALTA.
ORA-26041: DATETIME/INTERVAL datatype conversion error
The table in the database:
ID     NUMBER(10,0)
LITERAL     VARCHAR2(40 CHAR)
DESCRIPTION     VARCHAR2(255 CHAR)
FECHAALTA     TIMESTAMP(0)
FECHAMODIFICACION     TIMESTAMP(0)
How can I say to the CTL about the nulls?
Thanks in advance

How to use certain entries from a txt file as metadata?

So during my plugin development I stumbled on a problem.
I have created a txt file for each picture telling me who's in the photos. So the first column in the file shows all the names that appear in the photo.
I want to add those names into LR for each photo. I thought using them as metadata would be a good idea. Then I could let the user enter a name of some person and create a smart collection having all photos with that person in them.
But putting it into practice isn't that easy.
So I started with the classic metadata definition:
metadataFieldsForPhotos = {
id = 'Person',
title = 'Person'
dataType = 'string',
searchable = true,
browsable = true,
Now I don't know how to actually read only the column entries of the txt file and displaying all the names appearing in it. Another problem is that each photo has its own txt file in "nameofphoto.jpg.txt" So LR must know which txt file belongs to a photo.
I know my question isn't very specific but it would be great if someone could help...

Thank you for the reply. Reading the file how I wanted worked fine and I chose to use keywords, as you suggested.
So now I tried to add the keywords to the pictures and I get:
"LrCatalog:withWriteAccessDo: could not execute action 'keywordProvider'. It was blocked by another write access call, and no timeout parameters were provided."
There's my function so far:
function Finder.findPerson(smartCollectionName)
     local catalog = LrApplication.activeCatalog()
     local photos = catalog:getMultipleSelectedOrAllPhotos()
       LrTasks.startAsyncTask( function()
            for i=1,#photos do
                 local photo = photos[i]
                 local photopath = photo:getRawMetadata("path")
                 local photoname = photo:getFormattedMetadata("fileName")
                 local folderpath = string.sub(photopath, 1, string.len(photopath) - string.len(photoname))
                 local metadataPath = folderpath .. "\.metaface\\" .. photoname .. ".txt"
                 local text = LrFileUtils.readFile(metadataPath)
                 local metadataValues = stringSplit(text)
                 for i = 0, #metadataValues do
                      catalog:withWriteAccessDo( "keywordProvider", function()
                           local keywords = catalog:createKeyword(metadataValues[i])
                           photos:addKeyword(keywords)
                      end)
                 end
           end
      end)
end
So what am I doing wrong?

How continuously write data to a txt file

hello,
first of all, sorry for bad English, but I have a problem to continuously write data to the txt file.... I have one 2D array with values of some function and based on 2 sliders (values of the sliders) i want to interpolate value using bilinear method... and after that value of the sliders, interpolated value, and value of the nearest points i wish to write to txt file ... for every 2-3 seconds perhaps it would be ideal to be formated as ::
x y f f1 f2 f3 f4
but... first i have problem with writing data, because every time it deletes old data and just write new one and it's not horizontal... I'm very very new at this (it is obvious) and any help will be very appreciative
thanks

Hi there,
May I suggest you start with the LabVIEW tutorial? Or perhaps this one?
I say that because 1) you said you're new at this, and these tutorials are great for getting started; and 2) you don't seem to understand the concept of dataflow.
A structure, such as a loop or subVI or function, cannot start executing until it has all of its inputs available. Therefore, the loop which contains your file write (bottom loop) cannot execute until your top loop is done executing, because it depends on inputs from your top loop and those inputs aren't available until the top loop is finished. Thus, your file will contain only the data from your final top loop execution. You might be thinking that your loops are executing in parallel. They are not. Your file loop is executing after your data loop has finished...that is to say, your file loop executes exactly once, after you press your stop button.
You can do two things here to fix that:
1. You can move your file write into the top (data) loop. (probably easier for now)
2. You can use a queue to transfer the data from your top (data) loop into your bottom (file write) loop. (more complex, but a better idea in the long run)
One other thing. Move the "open file" function outside the loop. Opening and closing the file in each loop iteration will cause problems. Open the file once. Write to it in each loop iteration. Close it when you're done. Like this:
Note that this is not complete code...you need to provide the data to write. This is just to show you how to set up a continuous file write.
Ok, start with the tutorials and we'll go from there.

How to change encoding in output txt file
