Input a string value

What is the simplest method to accept an input of string value? Is buffering or string tokenizer required to perform this?

You might want to use BufferedReader's readLine method. Or you might want to use Scanner's next, nextLine, nextInt, etc. It depends on how you're consuming and parsing input. You might even want to check out the Console class introduced in version 6.
Start here, and play around with the above until you find what best suits your needs.

How to connect input string value to numerical values

Hello,
I am trying to figure out how to connect a single user's input string value to numerical values. Basically I want the user to input the name of a gas that I have a list for (I believe i put the list of gasses in an array>). Then I want to match 2 numerical values "a" and "b" depending on which gas name the user has put in. These "a" and "b" values will be automatically matched with the gas name from a list I put. For example the gas hydrogen has a value of 3 for "a" and 4 for "b. so when the user puts the name "hydrogen" in a string constant, automatically "a" and "b" should be outputted. I will be connecting a and b to a formula
Thanks for any help

This sounds a lot like an Enum to me. Make sure you type def the enum to make sure updates quickly and easily make it to all copies of the enums.

How to update a string value located on the main VI

Hello
I would like, from a subVI, to update a string value located in the main VI (using References). I was trying to find examples on NI web page but it´s impossible to download them (for more than one month : Error, File Not Found), do everyone has got the same problem?
Thanks for your answer
Nicolas

Hi,
this is from LV help file:
Complete the following steps to create a subVI that includes a control reference directly from a Property Node.
1.On the block diagram, right-click the front panel object terminal for which you want a control reference and select Create»Property Node from the shortcut menu to create a Property Node implicitly linked to the object. You can have multiple Property Nodes for multiple front panel objects.
2.Use the Positioning tool to select the new Property Node and select Edit»Create SubVI from menu. LabVIEW automatically creates a control reference to the control on the block diagram of the main VI, creates a subVI that contains a control refnum wired to a Property Node, and wires the control reference on the main VI to the
control refnum input terminal of the new subVI.
Note: Select several Property Nodes at once to create a subVI with multiple control refnums and Property Nodes.
3.Double-click the subVI to open it. Modify the Property Node and other elements of the subVI as you do in any other VI.
4. If you want to change values of control then select "Value" property in Property node.
I've attached the examples.
Good luck.
Oleg Chutko.

Can I pass a string value to a double numeric indicator?

I am doing a sequence of tests and saving each tests datas. When I bypass one of the tests, I need the string value 'BP' to get saved ( in the double numeric indicator ) for that particular test. Is there any possible way to do that?
Solved!
Go to Solution.

The numeric indicator works like a "Format into String" function with a hardwired numeric input.
So it really is a string indicator in the end.
You can use the "Format String" property node to modify how the numeric is displayed.
(Also available in Display Format ... --> Advanced Edit Mode.)
I don't think you can avoid displaying the numeric value, but you can add text.
So you could, for example, display: "0 BP".
Format string normal = "%#.2f";
Format string adding " BP" text = "%#.2f BP";
Some of the suggestions by others on this thread might be easier to manage and give a better result.
(You have to swap Format Strings around and still have the numeric displayed.)
*Note however, that this technique can be used to do interesting things like add Units to your numeric indicator.*

Problem in sending XML input as String in BPEL

Hi,
We have a BPEL flow (assign, invoke, assign) which takes an XML input as String.
<RegisterCustomerOnVAS><CustomerID>100</CustomerID><MSISDN>9999999</MSISDN><CustomerName>sanjeev</CustomerName><customerInfo>new user</customerInfo></RegisterCustomerOnVAS>
Assignment is doing fine, but when Invoke calls partner link, the input is getting parsed and only the first text value (eg 100) is getting passed to the partner webservice instead of the entire XML as string.
Can any one please help us in fixing in this problem.
Thanks

Hi,
You should watch your assign activity (maybe a bad assigment level in copy rule). I think the probem is there.

Switching between 2 string values

This is probably a trivial question, but how do I switch between 2 string values to be sent to one input terminal of a larger concatonated string function. The values need to be changed every 100ms or so.

Why so complicated???
You can do this particular string manipulation in a single atomic operation using "Append True/False String"

Parameters To Include Null Or Empty String Values

I have a table that has both Nulls & Empty Strings that I want to use as a Dynamic Parameter. Even though there is an indication of the Null/Empty String value when the parameter prompt comes up, selecting the value of Null/Empty String results in no records being returned. I have a formula to display the values in the report (where I substitute "Unknown" for the Null/Empty String values), but I am not able to do a parameter on that formula.
I guess in general, this is a situation of needing to be able to use a Dynamic Parameter based on a formula field.
Thanks for any assistance!
Edited by: Dragon77 on Apr 2, 2010 9:39 AM

I'd use a SQL Command as the data source for the list of values. Something like this... (MS SQL Server)
SELECT DISTINCT
CASE WHEN t.StringField IS NULL OR t.StringField LIKE ''
THEN 'Unknown' ELSE t.StringField END AS StringField
FROM TableName AS t
ORDER BY StringField
Then use a formula like this in the selection criteria.
IF {?Parameter} = "Unknown"
THEN (ISNULL ({TableName.StringField}) OR {TableName.StringField} LIKE "")
ELSE {TableName.StringField} = {?Parameter}

How to get string value from xml in JSF??

In JSF How to get string value from xml, .ini and properties file. I want to get string value from xml or text to JSF

Just use the appropriate API's for that. There are enough API's out which can read/parse/write XML, ini and properties files. E.g. JAXP or DOM4J for xml files, INI4J for ini files and Sun's own java.util.Properties for propertiesfiles.
JSF supports properties files as message bundle and resource bundle so that you can use them for error messages and/or localization.

How to get string value from database table using Visual Studio 2005?

Hi,

In the above code im geeting project D which is an integer value. But not able to get the project name.
Please some one guide me.

As I said in the other thread, this really isn't the place to ask questions about a database API unrelated to the Illustrator SDK. You're far more like to find people familliar with your problem on a forum that is dedicated to answering those kinds of questions instead.

When a ResultSet is returned to you, it is always positioned before the first row.
You need to insert a rs.next(); after your executeQuery().

How to include input user parameter values in XML report output?

How can i include input user parameter values in XML report output. I a have a report which can be run by providing start date and end date. I would like to include value of these parameters in XML output to enable me to figure out dates for report, just by looking at XML output.
Rgds,
manish

I think all the XML attributes can contain lexicals. If you bring up the property palette against the report object you can just set the following:
XML Tag Attributes: myParameter="&<P_1>"
where P_1 is your user parameter.

Encephalopathic wrote
Again, why?One of the problems (have been dued) in my codelab asks us to write a class as follow
Write a class definition of a class named 'Value' with the following:
a constructor accepting a single integer paramter
a constructor with no parameters
a method 'setVal' that accepts a single parameter,
a boolean method, 'wasModified' that returns true if setVal was ever called for the object.
a method 'getVal' that returns an integer value as follows: if setVal has ever been called, it getVal returns the last value passed to setVal. Otherwise if the "single int parameter" constructor was used to create the object, getVal returns the value passed to that constructor. Otherwise getVal returns 0.
The setVal(int y) returns nothing, so how do I know whether it has been called or not?
Thank you

Can't assign a string value to a member of type TEXT in Calculation Manager

I can assign a string value to that member of type TEXT using a run-time prompt of type StringToNumber.
Example: "My Text Member" = {string_rtp};
However, I need to accompllish the same function without using a run-time prompts.
I have a planning application and I know that text along with all other non-numeric
values are stored on the relational side in the planning application schema.
It seems reasonable to assume that if this can can accomplish
with a run-time prompt that I could do also do it without a run-time prompt.
What appears to be lacking is a function like:
"My Text Member" = @StringToNumber(<String Literal>);
Clearly, this is already being done "under the covers" for run-time prompts. If
would appear to be a minor enhancement to expose such a function to developers.
NOTE: I suppose you would also need to add new syntax/function to identify a string
literal from say a member name. I'm wondering if this is the more difficult challenge
from a product perspective????

When executing a Calculation Manager rule in Planning, the run-time prompt (RTP) is populated by looking up the outline information present in the relational Planning application database. If the RTP is of type TEXT, the strings displayed in the member select are from the from the relational Planning application database too. Subsequently when executing the Rule, the RTP's value is in fact the record ID (a number) which is then saved into the appropriate intersection in Essbase.
You need to bear in mind, the Rule is executed in Essbase. If Essbase needs to "write" a text, it would then need to connect to the Planning relational database to create a new record. The newly created record ID then needs to be feed back to Essbase, in order to store it in the appropriate intersection.
What you are suggesting, comes with a big overhead causing Essbase and the rule to slow. Thus, the disadvantages outweighs the advantages.
