Concatinating Strings into Variable Names

Hi
I'm not sure if this is even possible but here goes.
Is there anyway of concatinating (sp? Join together!) two strings and then use the new string as a variable name.
The reason I ask is that, depending upon what character I read into my program I will want to modify an array of data associated with that character.
For example if the character read in was @ I would want to modify the array data@. So my question is, is it possible to read in a character such as @, join it with the string "data" and then use the resulting string as a variable name?
Apologies if this has a simple solution but I'm struggling to come up with it by myself.
Many thanks.

Hey
Thanks for the advice. The problem is that I'm storing the arrays in a hash map already. This is because each character has more than one piece of data associated with it , and as far as I can tell each key entry in a hash table has one and only one piece of data associated with it. But if there is a way of storing multiple pieces of information with a particular key, then that could be a possible solution....
Any suggestions?

Assign string into variable

Hi All!
I''ve created global and lоcal variable with type - string
How can I assign the value into variable in BR?
I tried [Var_1] = "qwe"; or [Var_1] = @CONCATENATE (String_1, String_2) it doesn't work
Regards
Sasha

You should be able to take global/local variables from HBR into the code and use concatenate within the HBR.
Something like
@CONCATENATE([varName1], [varName2]) shouldn't be a problem, so long as the values are good.

Dynamic Variable name (for int/long) from a String variable

Hi,
I want to give a int/long variable name from a String.
for ex.
String str = lookup + "Id";
lookup is a String variable coming from XML. Now, for instance lookup="name". So str = "nameId".
Now I want to create a int/long variable by nameId.
Could anybody tell me the way how to do. Please don't tell to use MAP.
Edited by: Shah on Dec 5, 2007 3:26 PM

Well you can't. Use a Map.
The compiler translates variable names into slot numbers, either within an object or withing the local "stack frame" and these slot numbers are assigned names at compile time. No new slots can be created at run time. Java is not Basic.
Reflection allows you to find existing field names and methods (not local variables), so it's possible to map, for example, XML attribute names to field names or setters in an object but the names have to be known at compile time.

Process variable string into filename at Save service

Hello,
Does anyone know how to put a string into the Pathname Pattern (Template) property of a Save service (FileUtilsService - Write Document) ?
What I'm trying to do is strip the /'s out of a date string and put that date into a filename. For example, 042208_Greg.pdf
Instead I get d:\WMS\C0419\04\22\08\_Greg.pdf
I want: d:\WMS\C0419\042208_Greg.pdf
I have a Set Value service putting a form submit date (MM/DD/YY format) into a process variable called @stringDate. I am stripping /'s out of the date and setting @stringDate like so: /process_data/@stringDate <--- concat(substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approvers/Init iator/Date,1,2),substring(/process_data/xfaform/object/data/xdp/datasets/data/C0419/Approv ers/Initiator/Date,4,5),substring(/process_data/xfaform/object/data/xdp/datasets/data/C041 9/Approvers/Initiator/Date,7,8))
At the Save file service, I am using @stringDate in my Pathname Pattern (Template) to create the filename: d:\WMS\C0419\{/process_data/@stringDate}_{$/process_data/xfaform/object/data/xdp/datasets /data/C0419/Approvers/Initiator/CompletedBy/Name$}.pdf
Thanks,

Hi Greg
You've done a great job getting this done with xpath.
It looks to me like you've done everything right - what's not working - are you getting an exception, or is the file being saved with the wrong name?
There is a nice little DateFormatter component here, that might make things a little easier/flexible.

Variable name to string

Hi, I'm really new to TestStand, so this is probably an easy question:
I'm using TestStand 4.5 and I'm trying to convert the name of a variable, Locals.MaxArrayIndex, which is a numeric variable, into a String, Locals.VarString.
I know that the Str() function can be used to convert a numeric into a String, but how can I store the actual words "Locals.MaxArrayIndex" in a string?
Thanks!

Hmmm...it works great for Parameters that are arrays, but for me it won't work if the Parameter is a numeric variable. Maybe I'm making a mistake somewhere else that I'm not picking up; so I attached the sequence file if you want to take a look at it.
The issue arises in the 'Else' statement. I'm pretty sure the syntax in my function and popup are correct, but the String (ParamName) that is supposed to hold the value of the Parameter variable name (DataSelect) doesn't seem to ever be filled and outputted in the error message.
I would really appreciate it if any of you guys could have a look at the file (I'm sure I'm making some kind of really rookie mistake)
Thanks!

Generate variable name from a String

I've got a String "MyVariable" and I need to reference a static variable named MyStaticClass.MyVariable. How do you turn a String into a variable name?

You can't easily do it... you can using reflection:
MyStaticClass.class.getField().getXXX("MyVariable") //depending on what type the field is...But this seems like it may be a flawed design. Maybe you should try making a static HashMap in the class, use a Static init block and static get/set methods:
public class StaticClass
    static Map properties;
    static
        properties = new HashMap();
        properties.put("MyVariable", "Some Value");
        properties.put("OtherVariable", new Integer(3));
    public static Object get(String property)
        return properties.get(property);
    public static void set(String property, Object value)
        //Maybe some code checking to make sure object is right type
        //or don't use a set method at all to make the properties immutable
        properties.put(property, value);
}

Obtain string of IN variable name in PL/SQL

Hi,
Odd question. Is there a way to access an IN variable's object name in a procedure?
eg.
procedure (var1    IN VARCHAR2(6),
                var2    IN VARCHAR2(6),
                var3    IN VARCHAR2(6))
IS....You run this procedure and pass in parameters of:
var1 => 'abcdef',
var2 => 'defghi',
var3 => 'ghikjl';
In the code, I want to access the number in the string of the +variable name: var1+
In a naive sense,
num_of_in_var := substr(var1, 4,1) would be what i was hoping to achieve, but,
var1 is set to 'abcdef' so,
num_of_in_var := substr(var1, 4,1) would return 'd'.
Any thoughts?
Thanks

Here's an example of how (what you want to do using a procedure or function), can be done using a ADT/UDT (Advance/User Defined Type) in Oracle.
This approach will not work for standard procedures and functions as this type of dynamic referencing of the code unit/object to itself, is not possible.

How to build a connection string if "Only variable names (i.e.: $variable) may be used as the target of an assignment statement."

im looping through databases on a server & building a connection string to each database.
$SQLConn.ConnectionString = "Server=$SrvName; Database=$DBName; User ID =DBLogin; Password=myPassword;"
The problem is i get this error:
Only variable names (i.e.: $variable) may be used as the target of an assignment statement
I can put the code into an Inlinescript, but then I lose the ability to perform paralellism. Is there any way to construct the connection string in PS Workflow without using an Inlinescript?

Hi Winston,
Why not just wrap the InlineScript blocks in a Parallel block, to cause them to execute in parallel?
For example:
workflow foo {
parallel {
inlinescript {
start-sleep -Seconds (Get-Random -Minimum 1 -maximum 5)
"a"
inlinescript {
start-sleep -Seconds (Get-Random -Minimum 1 -maximum 5)
"b"
Sometimes outputs "a b" and sometimes outputs "b a"

Need to validate file Name,split the file name and store the splited values into Variables

Dear All,
Below is the my requirement.
I have a folder, in that folder I have bunch of text files. The file name is below format
ACA_122_pay_20140430_001
Initially the file name start with ACA code,groupid,group name and date time stamp. This is the standard structure of file name.
I want to check each and every file in the folder with this structure. The structure should be standard for all the files. If the structure same for all files I need to get codes form file name. For example
If you see the below file name, I need to get ACA and put into variable,I need to get 122 and put into variable. For group name and date time needs to put in variable.
If the file format is not valid state then I need to log exception.
Let me know if I am not clear.
Kindly provide the C# code for achieving the above requirement.
As I am new to .net programming. kindly help me.
Thanks in Advance,

Using contents of a String as the name for a variable

I'm trying to write code that will evaluate the contents of a String variable and then use the contents as the name for an object. For example, my program will create an unknown number of Student objects. I would like to name the Student objects student1, student2,... . In the code below, how do I get the last line of the method to create a new Student called something like "student3" instead of "varName"? Thanks, Julie
int numberOfStudents= 0;
public void createStudent()
   numberOfStudents++;
   String varName = "student" + numberOfStudents;
   Student varName = new Student();
}

The name of the reference variable is irrelevant to the functional aspect of the application. The 'Name' should be a property of the student class. EG
class Student {
private String name;
public String getName() { return name; }
public void setName() { this.name = name; }
public Student() { this(null); }
public Student(String name) { setName(name); }
now your code becomes
public void createStudent() {
numberOfStudents++;
Student newStudent =
new Student("student"+numberOfStudents);
// now do something with the new student...
If you're expecting to use the 'Student' instance outside of this method you need to store a reference to it somewhere more accessible (like a field, in a list or an array) or return the reference from this method...

Putting quote round a variable name to make a string

Hi,
Hopefully this is a fairly simple task.
I would like to take a variable name, say Hyp, from my main program and call it in a class, captured in a variable called A and create a string with double quotes surrounding it... to give an answer of "Hyp" which can be used in my program for a further class call which needs the name in quotes.
I've tried using
String concat = """+A+""" but this results in an invalid AssignmentOperator
If I use
String concat = ""+A+"" I get Hyp with out the quotes - not what is required
If I use
String concat = "'"+A+"'" I get 'Hyp' which does not work with the further class which requires "Hyp"
Can anyone help?

Escape it with a \ like this:
String concat = "\""+A+"\"";

Substitute a variable name by String ?

Hi
is it possible to substitute a variable name by a String ? if yes then please tell me how :-)
thx

You might be able to use the Reflection API to get what you want, but every other time this question's been asked the asker really needed to use a HashMap instead...
Good Luck

Accessing variable names using String

I have to check up to 13 JCheckBox variables to see if they are checked or not, and I have the variables named: count1, count2, count3,...,count13. I wanted to know if there was a way to go through them in a while loop until I found the last one that was checked. I want to do the following:
int i = 1;
while([count+i].isSelected()) {
i++;
int foodCount = i;
//foodCount is stored in database
I am doing this for a pet store and I don't want to have 12 extra columns in the database - I just want to have one for the overall food count. Any ideas how I can dynamically create a variable name?

Put the JCheckBoxes in an arrayJCheckBox[] myCheckBoxes = {check1, check2, check3,...,check13};
JCheckBox someCheckBox = null;
for (int x=0; x<myCheckBoxes.length; x++) {
if (myCheckBoxes[x].isSelected()) someCheckBox = myCheckBox[x];
}

Anonymous PL/SQL . Illegal variable Name/number.

Hi
I have tested ODP.NET in ASP.NET for upload images. But when read back from DB then save image to local drive. When I tested given sample code working fine. But when I modify code only select statment in PL/SQL it gives error.
Following statment is the error. Illegal variable Name/number. Pl.
advice me what need to change.
Dim block As String = " BEGIN " & _
" SELECT Ad_Image into :2 from Printmedia WHERE Product_ID = " + ProdID + ";" & _
" end ;"

You use bind variables. Great!
And then you do not use bind variables. Bummer!!
Why can you make the output from the SQL a bind variable, but you do not supply Product ID as a bind variable? This causes a unique and non-sharable SQL statement in the SQL Shared Pool. Where the emphasis is very obvious - shared SQL.
The definition should be something like this:
Dim block As String = "BEGIN SELECT Ad_Image into :1 from Printmedia WHERE Product_ID = :2; END;"But why are you using an anonymous PL/SQL block and a bind variable to get to the image? Deal with it as a cursor. Much easier. E.g.
Dim cursorSQL As String = "SELECT Ad_Image FROM Printmedia WHERE Product_ID = :1"Open the cursor. And there you have the resulting image column as a result.

There are several problems with your input:
1. Your xml is not well-formed because the attribute values should be enclosed withing double " quotes and not single ' quotes;
2. You use a prefix (sml) for the folowing part but you dont define the namespace:
<ids>
<VID ID="new"/>
<data>
<*sml:*attr name="std">
<sml:value></sml:value>
</sml:attr>
<sml:attr name="xde">
<sml:value></sml:value>
</sml:attr>
</data>
</ids>
Complete message should be:
<ids xmlns:sml="somenamespace">
<VID ID="new"/>
<data>
<sml:attr name="std">
<sml:value></sml:value>
</sml:attr>
<sml:attr name="xde">
<sml:value></sml:value>
</sml:attr>
</data>
</ids>
3. Do you assign this expression to a variable that is based on the schema of your message you want to parse
