Can a structure be stored in a string using structure notation

Is there any way to store a structure as a string, for
example in a database, that could be converted runtime like
javascript can with eval, something like <cfset
tmp=Evaluate("{VarA=[1,2,3]}")>

The closest you can come is if you want to serialize and
deserialize the structure as a JSON object (JavaScript Object
Notation).
<cfscript>
struct = StructNew();
struct.key1 = "Key 1";
struct.key2 = "Key 2";
struct.key3 = "Key 3";
myJSONStruct = SerializeJSON(struct);// converts the
structure to a JSON string
myStructBack = DeserializeJSON(myJSONStruct);
</cfscript>
<cfdump var="#myJSONStruct#" />
<cfdump var="#myStructBack#" />
Of course, you'll need to know how to use a JSON
string/object in your JS for this to be helpful but this will
convert your struct to a string representation and allow you the
option to convert it back in CF, if needed.

Can I Execute a function whose name is stored in a string variable?

Can I execute a function whose name is stored in a string variable?
Like
Depending on the condition I will stroed the name of the function in a string variable. Then using that string variable i want to execute the function.
String str=��
iVal an int can take ne value
Switch(iVal)
Case 1:
str=�test1()�;
Case 2:
str=�test2()�;
I want whatever function name is in str to be executed.

For just executing a method or two, reflection might be easier than beanshell (or it might not). For executing entire scripts, beanshell will be preferable over reflection.
(I assume beanshell uses reflection under the hood, but I've never bothered to peek.)

How can I export formatted text from a string indicator?

Does someone know how I can export formatted text (i.e., parts of the text have different formatting, such as color, fontsize, etc.) from a string indicator? Using copy/paste does not work, as it only exports unformatted plain text.

Hello Sparti,
Thank you for your suggestions, they are all very useful, and I plan to use the HTML feature under Report Generation to export the formatted text from Labview. However, I am still not sure how I can extract the formatted text from a *string indicator* and transfer it to one of those VIs, so that it can be exported to other applications. Let me give some more specific info on what I am trying to achieve: I am monitoring the communication between two pieces of equipment. A string indicator shows all the data flow, with different colors for data coming from different instruments. I managed to do that by using a property node and playing with the selection and font color properties. Now, if you just wire the output of the string indicator, the formatting is gone and all you get is just plain black text (for instance, try to programmatically transfer the formatted text from one string indicator to a different string indicator and you will see that the formatting is not preserved). Even if you try the "brute force" method of manually selecting and copying the text in the indicator and pasting it to Word, LV does not export the formatting. But, if you paste *within* LV (for example, paste it to a string constant in your diagram), then it works. To extract the formatted string from the indicator, I also tried to use a property node, but without success. I am trying to avoid duplicating part of my code to generate the same color-coding scheme on a report. It would be way easier to be able to transfer the formatted text from the string indicator. This is particularly annoying, because the information is there, stored in the data structure associated with the string indicator. But how can I put my hands on it? Any ideas?

Pointbase : How can I create a stored procedure with Pointbase database?

Hello,
Excuse me for my english, I'm not anglophone. I try to create a stored procedure.
This is my file SampleExternalMethods.java :
import java.sql.*; //import com.pointbase.jdbc.jdbcInOutDoubleWrapper; public class SampleExternalMethods { // A connection object to allow database callback static Connection conn = null; static Statement l_stmt; static Statement m_stmt; static CallableStatement m_callStmt = null; static ResultSet l_rs = null; public static void main(String[] args) { try { String url = "jdbc:pointbase:server://localhost/pointbaseDB"; String username = "PBPUBLIC"; String password = "PBPUBLIC"; conn = DriverManager.getConnection(url, username, password); doCreateProcedure(); doInvokeProcedure(); } catch (SQLException e) { e.printStackTrace(); } finally { if (m_stmt != null) { try { m_stmt.close(); } catch (Exception e) { e.printStackTrace(); } } if (m_callStmt != null) { try { m_callStmt.close(); } catch (Exception e) { e.printStackTrace(); } } if (conn != null) { try { conn.close(); } catch (Exception e) { e.printStackTrace(); } } } } public static void getCountry(String Iso_Code) { try { // Query the database for the country iso code l_stmt = conn.createStatement(); l_rs = l_stmt.executeQuery( "SELECT * FROM countries" + " WHERE country_iso_code ='" + Iso_Code + "'"); //Affichage du résultat de la requête l_rs.next(); System.out.print(l_rs.getString(1) + " - "); System.out.print(l_rs.getString(2) + " - "); System.out.println(l_rs.getString(3)); // Close the result set l_rs.close(); } catch (SQLException e) { e.printStackTrace(); } finally { if (l_rs != null) { try { l_rs.close(); } catch (Exception e) { e.printStackTrace(); } } if (l_stmt != null) { try { l_stmt.close(); } catch (Exception e) { e.printStackTrace(); } } } } public static void doCreateProcedure() throws SQLException { // SQL statement to create a stored procedure String SQL_CREATE_PROC = "CREATE PROCEDURE getCountry(IN P1 VARCHAR(30))" + " LANGUAGE JAVA" + " SPECIFIC getCountry" + " NO SQL" + " EXTERNAL NAME \"SampleExternalMethods::getCountry\"" + " PARAMETER STYLE SQL"; // Create a SQL statement m_stmt = conn.createStatement(); // Execute the SQL m_stmt.executeUpdate(SQL_CREATE_PROC); // Close the statement //m_stmt.close(); } public static void doInvokeProcedure() throws SQLException { // Create SQL to invoke stored procedures String SQL_USE_PROC = "{ call getCountry(?) }"; // Create a callable statement with three binding parameters m_callStmt = conn.prepareCall(SQL_USE_PROC); m_callStmt.setString(1, "CA"); m_callStmt.executeQuery(); // Close the callable statement //m_callStmt.close(); } }
Afterwards, I have read this note in a Pointbase document:
To invoke the dateConvert external Java method from a stored function, you must use the
CREATE FUNCTION statement. The dateConvert external Java method is called from the
class, SampleExternalMethods.
In order for the database to access this external Java method, the class SampleExternalMethods
must be included in the database CLASSPATH. For PointBase Embedded - Server Option, it
must be in the Server CLASSPATH, but not in the Client CLASSPATH.
If PointBase Server is run with the Java Security Manager, in the java policy file grant
’com.pointbase.sp.spPermission’ to the class that implements the external Java method.
An "spPermission" consists of a class name with no action. The class name is a name of a class
that could be used in creating a Stored Procedure in PointBase. The naming convention follows
the hierarchical property naming convention and that is supported by
"java.security.BasicPermission". An asterisk may appear by itself, or if immediately preceded
by ".", may appear at the end of the name, to signify a wildcard match. The name cannot
contain any white spaces.
I'm not sure, but I suppose that I must include the class SampleExternalMethods in a .jar file.
The database CLASSPATH could be : C:\Sun\AppServer\pointbase\lib\
These my files in this database CLASSPATH:
pbclient.jar
pbembedded.jar
pbtools.jar
pbupgrade.jar
I have tryed to include the class SampleExternalMethods in pbclient.jar and pbembedded.jar with this command:
jar -uf pbembedded.jar SampleExternalMethods
Afterwards I do that,
1) Start Pointbase
2) Configuration of classpath
set classpath=C:\Sun\AppServer\pointbase\lib\pbclient.jar
set classpath=%classpath%;D:\J2EE\Ch07Code\Ch07_06
I precise that my file SampleExternalMethods is into D:\J2EE\Ch07Code\Ch07_06\Ch07.
Then, I run the program:
D:\J2EE\Ch07Code\Ch07_06>java -Djdbc.drivers=com.pointbase.jdbc.jdbcUniversalDriver Ch07.SampleExternalMethods
But I have an error message:
Exception in thread "main" java.lang.NoClassDefFoundError: Ch07.SampleExternalMethods (wrong name: SampleExternalMethods)
at java.lang.ClassLoader.defineClass0(Native Method)
at java.lang.ClassLoader.DefineClass(ClassLoader.java:539)
The problem, I suppose, comes from that the class SampleExternalMethods
must be included in the database CLASSPATH, but there is a pbserver.jar with pointbase normally, but I didn't find it. That's why I use pbembedded.jar or pbclient.jar in order to include the class SampleExternalMethods. May be I must start from C:\Sun\AppServer\pointbase\lib\ instead of D:\J2EE\Ch07Code\Ch07_06\Ch07?
Please, can somebody helps me?
Thank you in advance.

How to create an instance of a class which is stored in a String?

I've class name stored in a String Object.
now i've to create an instance of that class name.
How?

This is very dangerous ground because you give up compile-time safety, but you can get a Class object using Class.forName(String). Then you can use methods of the class Class to operate on it (including creating an instance).

How to create a new file having a name that is stored in a string

Hello friends i am new to java and i need your help .
I have a string which will take different values at run time. I want to create a file which has the same name as stored in the string . Can anyone help me?

The Java Almanac example I linked to uses createNewFile() - the API documentation is not particularly clear about exactly what happens if c:\some\value\assigned\at doesn't already exist. But you're only a small experiment away from finding out!
Another page gives examples of directory creation.
http://www.exampledepot.com/egs/java.io/CreateDir.html
Once (or if) the file is created using a File then, yes, that File is the name of the file: parent directories and all. If you create a FileReader based on the File it will read from the right place.

How can I convert an ArrayList to a String[]

Hi,
How can I convert an ArrayList (only with strings) to a String[] ?
I've tried this :
     public static String listToString(List l) {
          StringBuffer sb = new StringBuffer();
          Iterator iter = l.iterator();
          while (iter.hasNext()) {
               sb.append(iter.next().toString());
               if (iter.hasNext()) {
                    sb.append(',');
          return sb.toString();
But what I get is an array of xxxxx@435634 (for example).
Thanks a lot !

Strings are Objects but not all Objects are Strings and at least one of the elements in your List is not a String.

hi,
of course there are better ways to crypt your code, but the following 2 functions do their job....
as far as i know java has an own api for crypting stuff.
private String GetEncryptedString(String aCryptedString)
String result = "";
String str = aCryptedString;
int[] asciiArray = new int[str.length()];
for(int i = 0; i < asciiArray.length; i++)
asciiArray[i] = (int)str.charAt(i);
char tempChar = (char)(asciiArray[i]+3);
result = result+tempChar;
return result;
private String GetDecryptedString(String aString)
String result = "";
String str = aString;
int[] asciiArray = new int[str.length()];
for(int i = 0; i < asciiArray.length; i++)
asciiArray[i] = (int)str.charAt(i);
char tempChar = (char)(asciiArray[i]-3);
result = result+tempChar;
return result;

How to find out the type of the value stored in a string variable?

Hi,
How do i find out the type of the value stored in a string variable?
for example,
I have a string variable str, in which the following type of values wil be stored
1) Intger
2) Long
3) boolean
4) Char
Is there any method to find out the type of the value, anything like str.getType()?. Please kindly help me. Thanks in advance.

Hi All, i'm sorry for the double posting, by mistake it occured.
Thanks for your replies, i have a string variable str, in which the value is stored and i have another string variable type, in which the type of the value is stored.
For example,
String str = "15";
String type = "Integer";
Is there any way to verify whether the value stroed in str is of type stored in the variable 'type'. I want to write a method of type boolean, it will throw true of the value stored in str is of type 'type'. Thanks
