Reading from a variable "a.x"
hi,
i have a variable which is named as "a.x". i need to read this variable to get the value that is stored in this variable..
how do i get it..
can java identofy such variables
i want the value of this variable directly..do not
want to write it to a third variableThis does not make any sense. If you don't want a "third" (aka second) variable then just do
properties.get("a.x");wherever you want to use that variable.
>
I open the properties file,Okay.
my question , is how do i retrieve the value from a
a variable which has a dot in its variable nameI already told you.
Look the answer is right here and if you aren't getting it it's rather difficult to understand why unless you make some effort to communicate a coherent question.
Why don't you do as I asked previously and post some code demonstrating what in the heck you are trying to do and why you wrongly think that I am not giving you your answer.

Inserting in the UUT_Results table a value that we read from our data base from a local variable
We would like to include in the UUT_Results table a value that we read from our data base into a local variable during the execution of our sequence file. We found that by modifying the configure database options we were able to add a column for this variable, but the local variable was not available to be placed into an expression for that column from the local variables or parameters. Is it possible to do this, and if so, how? Station Globals were available to be included in the expression, however the sequence file may be executed on more than one system which makes the Global unavailable on systems other than the one where the sequence file originated.
You can use the TestStand API to programmatically create global variables at runtime, thus ensuring their existence. For example, you could call Engine.Globals.SetValString("GlobalStringVariableName", PropOption_InsertIfMissing, "variable value")
Of course, if you need to test multiple UUTs in parallel, a single global is not sufficient. In that case you might consider adding the field you need to the UUT datatype in the process model. You could then access the field in your sequence via RunState.Root.Locals.UUT.YourNewField = YourNewValue.
If you also want your sequence to run without using a process model, you must check for the existence of the UUT before accessing it. You could use the expression function: PropertyExists("RunState.Root.Locals.UUT.YourNewFi

Reading non-standard variable types from file
Hi,
I'm currently on a programming course, and I need some help with an excercise.
The excercise is about adding save, load and undo features to an Infocom style text adventure. The save file must contain three variables: The location of the player (Area), the items the player had (ArrayList<Item>) and the number of passed turns (int.)
Is it possible to write to & read from file with these type of variables? Or do I have to convert them to Area to String (saving) and from String to Area (loading)?
Thanks for the help in advance.You should probably take a look at Java Serialization (google on that)

Reading a global variable from tomcat with JNDI. Example not working
Hi you can help me to make this example work?
Context initCtx = new InitialContext();
Context envCtx = (Context)initCtx.lookup("java:comp/env");
Object o = envCtx.lookup("testvariable");
<GlobalNamingResources>
<Environment name="testvariable" type="java.lang.Boolean" value="false"/>
Nice greetings ChristianI found out that in addition to having the JNDI lookup code, you have to
- have the environment variable declared in the app server configuration
- have a resource-env-ref entry in your webapp module
- have the application container bind your named variable with the global variable
I am using tomcat 5.5, and have done the following. with success.
the following example uses the default sample environment variable in the tomcat server.xml
in tomcat server.xml:
<GlobalNamingResources>
<Environment
name="simpleValue"
type="java.lang.Integer"
value="30"/>
</GlobalNamingResources>
in my application's web.xml:
<resource-env-ref>
<description>Test read resource environment variable</description>
<resource-env-ref-name>simpleValue</resource-env-ref-name>
<resource-env-ref-type>java.lang.Integer</resource-env-ref-type>
</resource-env-ref>
in my META-INF/context.xml (or otherwise, in tomcat's context deployment configuration)
<ResourceLink name="simpleValue" global="simpleValue"
type="java.lang.Integer"/>
Note: in theory, the named resource by your web app could be different from the global environment variable, but here they are the same 'simpleValue'
This is the really important step, that with out it, nothing works.,
the context.xml is known to work with tomcat when it exists in META-INF/context.xml inside the .war file (i use war files to deploy, but you should be able to create META-INF/context in an unpacked webapp directory too, and tomcat will find it.,
I can not say what it is like for other app servers, but this mapping step is the critical point that i discovered after A LOT of hair pulling.
then, make use of it, i created a jndiTest.jsp:
<%@ page import="javax.naming.Context" %>
<%@ page import="javax.naming.InitialContext" %>
<%@ page import="javax.naming.NamingException" %>
<%
try {
Context initCtx = new InitialContext();
Context ctx = (Context) initCtx.lookup("java:/comp/env");
Object o = ctx.lookup("simpleValue");
%>
<%=o%><br>
<%
catch (NamingException ex) {
System.err.println(ex);
%>
since my server.xml defines the value for 'simpleValue' to be 30, this page displays 30 -
Is it possible to read Essbase Substitution variables from ODI?
Is it possible to read Essbase Substitution variables from ODI?
Hi,
You can do it with custom code, if you have a read of a blog I wrote :- http://john-goodwin.blogspot.com/2009/11/odi-series-planning-11113-enhancements.html
About half way through I go into reading essbase sub vars using the essbase java API.

StringTokenizer to read in 4 variables from the command point
Hi,
I need to set up the Java StringTokenizer to read in 4 variables
from a command prompt. It should be in the following format:
X variable1 variable2 variable3where
(is the command prompt)X (is either +, -, *, /, c, or e)
variable1 variable2 and variable3 are integers.
I would appreciate any answers that would help me find the way!
Thanks in advance.Thank you for the code snippet, but the program does not function that way. Ie, it does not accept
arguments when the program is first run, only after the program has excecuted.
The program is to enter a simple command prompt, and await instructions in the form X int1 int2 int3
where X can be c (convert the number int3 from number base int1 to number base int2), e (exit the
program), +,-,/,* (add, subtract, divide or mutilply int2 to/by int3 in number base int1). Here is an example
of the what the program execution should look like:
c:\programming\java nbc
> + 10 23 45 // Add 23+45 in base10
68 // Write the answer on a new line and prompt
- 16 5A 2C // Subtract 5A-2C in base 162E // Write the answer on a new line and prompt
c 15 7 2E // Convert 2E in base 15 to base 762
e // End of programc:\programming\
My problem is, I do not know how to convert the first token to a variable that can be used to carry out one of
the above mentioned procedures. For example, the first token taken from the command c 15 7 2E is "c".
As I understand it, "c" is simply a string, and this cannot be used in logical procedures such as:
int procedure = 0;
if(operator == "c")
procedure = 0; //then use this variable
}else
if(operator == "e")
System.exit(0): //quit the program
Also, how can I set up a while loop to continuesly
prompt the user for an instruction until "e" is entered?import java.io.*;
import java.util.*;
import java.util.StringTokenizer;
public class blerk
public static void main(String[] args) throws IOException
InputStreamReader stdin = new InputStreamReader(System.in);
BufferedReader br = new BufferedReader(stdin);
boolean e = true;
String str = "";
String symbol = "";
int value0 = 0;
int value1 = 0;
int value2 = 0;
System.out.print(">");
str = br.readLine();
StringTokenizer st = new StringTokenizer(str, " ");
int i = 0;
int option = 0;
while (st.hasMoreTokens())
switch(i)
case 0:
symbol = st.nextToken();
// This part is obviously not correct. How can this be implemented to select and store the operating procedure the user enters?
if(symbol = "e")
System.exit(0);
}else
if(symbol = "c")
}else
if(symbol = "+")
option =
break;
case 1:
value0 = Integer.parseInt(st.nextToken());
break;
case 2:
value1 = Integer.parseInt(st.nextToken());
break;
case 3:
value2 = Integer.parseInt(st.nextToken());
break;
default:
System.out.println("format: >operator x y z");
break;
i++;
System.out.println(symbol + value0 + value1 + value2); //test
Any advice would be most appreciated.

Problem with ArrayLists and writing and reading from a .dat file (I think)
I'm brand new to this forum, but I'm sure hoping someone can help me with a problem I'm having with ArrayLists. This program was originally created with an array of objects that were displayed on a GUI with jtextFields, then cycling thru them via jButtons: First, Next, Previous, Last. Now I need to add the ability to modify, delete and add records. Both iterations of this program needed to write to and read from a .dat file.
It worked just like it was suppose to when I used just the array, but now I need to use a "dynamic array" that will grow or shrink as needed: i.e. an ArrayList.
When I aded the ArrayList I had the ArrayList use toArray() to fill my original array so I could continue to use all the methods I'd created for using with my array. Now I'm getting a nullPointerException every time I try to run my program, which means somewhere I'm NOT filling my array ???? But, I'm writing just fine to my .dat file, which is confusing me to no end!
It's a long program, and I apologize for the length, but here it is. There are also 2 class files, a parent and 1 child below Inventory6. This was written in NetBeans IDE 5.5.1.
Thank you in advance for any help anyone can give me!

ResizeImage using dimensions read from text file
XP Pro
CS
1GB Ram
Javascripting
Currently have the following code which works great.
if (largePrefsIsOpen) {
docRef.resizeImage(289,null);
I am encountering a problem with trying to put a variable in the dimension area (289,null)
I am reading a file that contains only the string "289,null" and want to read that into the resize paramaters as follows...
if (largePrefsIsOpen) {
docRef.resizeImage(largePrefsContents);
I can see the value of largePrefsContents is "289,null" minus the quotes but the image is resized to the following pixel dimensions 1 X 7.
The dimensions are read from a text file and put in the variable "largePrefsContents" but for some reason it is not resizing to that.
Any help would be greatly appreciated.
JeffThank you all very much.
Paul R's and try67's solution both work.
I can make this work but there still is an easier way for this - There has to be. :-)
I would still love to be able to parse as in the original string from the text file "289,null". The reason being is that sometimes the image may be resized based on the height and that would leave the width null (null,289).
That may not work in those cases because you won't know what is an integer and I have already thought through some lengthier code to make it work, but we all are trying to do the same thing - simpler and fewer lines of code are better.
I think I would like to parse the list as first suggested by Mark Walsh and then take the advice from Paul R and try67 and work towards a solution for the parsed portions of the text file.
I really do appreciate your time in looking this over.

LabVIEW for ARM 2009 Read from text file bug
Hello,
If you use the read from text file vi for reading text files from a sdcard there is a bug when you select the option "read lines"
you cannot select how many lines you want to read, it always reads the whole file, which cause a memory fault if you read big files!
I fixed this in the code (but the software doesn't recognize a EOF anymore..) in CCGByteStreamFileSupport.c
at row 709 the memory is allocated but it tries to allocate to much (since u only want to read lines).
looking at the codes it looks like it supposed to allocated 256 for a string:
Boolean bReadEntireLine = (linemode && (cnt == 0));
if(bReadEntireLine && !cnt) {
cnt = BUFINCR; //BUFINCR=256
but cnt is never false since if you select read lines this is the size of the file!
the variable linemode is also the size of the file.. STRANGE!
my solution:
Boolean bReadEntireLine = (linemode && (cnt > 0)); // ==
if(bReadEntireLine) { //if(bReadEntireLine && !cnt) {
cnt = BUFINCR;
and now the read line option does work, and reads one line until he sees CR or LF or if the count of 256 is done.
maybe the code is good but the data link of the vi's to the variables may be not, (cnt and linemode are the size of the file!)
count should be the number of lines, like chars in char mode.
linemode should be 0 or 1.
Hope someone can fix this in the new version!
greets,
Wouter
Wouter.
"LabVIEW for ARM guru and bug destroyer"I have another solution, the EOF works with this one.
the cnt is the bytes that are not read yet, so the first time it tries to read (and allocate 4 MB).
you only want to say that if it's in line mode and cnt > 256 (BUFINCR) cnt = BUFINCR
the next time cnt is the value of the bytes that are not read yet, so the old value minus the line (until CR LF) or if cnt (256) is reached.
with this solution the program does not try to allocate the whole file but for the max of 256.
in CCGByteStreamFileSupprt.c row 705
if(linemode && (cnt>BUFINCR)){
cnt = BUFINCR;
don't use the count input when using the vi in line mode. count does not make sense, cnt will be the total file size. also the output will be an array.
linemode seems to be the value of the file size but I checked this and it is just 0 or 1, so this is good
update: damn it doesn't work!
Wouter.

Java - Write And Read From memory Like CheatEngine ( Writing not working?)
Hello Oracle Forum
I came here some time ago to ask about javaFX , i solved all my issues and im right now waiting for javaFx tot ake over swing and hmm, im working on learning LIBGDX to create games in java.
However, im in need to create an app to change values of memory to fix a bug in an old program that i have, and the only way until now is using cheatEngine, So i decided to take a tutorial and learn how to do that in java.
Well, im able to read from the memory but the write isnt working somehow... Im posting the code here, if anyone can give me a hint, i would thank and a lot, because theres a community that really needs this app to automate the fix without using cheat engine.

http://pastebin.com/Vq8wfy39Hello there,
this tutorial was exactly what I needed, so thank you.
Your problem seems to be in this line:
int writeMemory = writeMemory(writeprocess, address, new short[0x22222222]);
The problem is, you're creating a new short array with the length of 0x22222222. Which not only results in an java.lang.OutOfMemoryError: Java heap space
but also, if it would work, would create an empty array with the length of 0x22222222.
I think you want to write 0x22222222 as value in your address.
Correctly stored the code you'd need to write would be:
short[] sarray = new short[]{(short) 0x22222222};
But because the value is too long for the short, the value stored in your array would be the number 8738.
I think, what you want to do is to store the number 572662306, which would be the hex value, stored in an int variable.
So first of all you need to strip down your hex-value to shorts:
Short in Java uses 16 Bit = 2 Byte. 0x22222222 -> 0x2222 for your high byte and 0x2222 for your low byte
So your array would be
short[] sarray = new short[]{0x2222,0x2222};//notice, that sarray[0] is the lowbyte and sarray[1] the high byte, if you want to store 20 it would be new short[]{20,0} or if you use hex new short[]{0x14,0x00}
The next part is your writeToMemory Method. If I'm right, the method in the tutorial is a little bit wrong. The right version should be this:
public static int writeMemory(Pointer process, int address, short[] data) {
IntByReference written = new IntByReference(0);
int size = data.length*Short.SIZE/8;
Memory toWrite = new Memory(size);
for (int i = 0; i < data.length; i++) {
toWrite.setShort(i*Short.SIZE/8,
data[i]);
boolean b = kernel32.WriteProcessMemory(process, address, toWrite,
size, written);
return written.getValue();
You need to calculate your offset right. And the size of your memory. Maybe you could write this method not with shorts, but with integers. But this should work.
If you pass your new array to this function, it should write 0x22222222 to your adress. If you read out your toWrite value with toWrite.getInt(0) you get the right value.
And there is one more thing. In order to write data to a process, you need to grant two access rights:
A handle to the process memory to be modified. The handle must have PROCESS_VM_WRITE and PROCESS_VM_OPERATION access to the process.
You have to grant the right to write data: PROCESS_VM_WRITE: 0x0020 and PROCESS_VM_OPERATION: 0x0008
So your writeProcess needs to get initialized this way:
Pointer writeprocess = openProcess(0x0020|0x0008,pid);
I hope this works for you. Let me know.
Greetings
Edit:
Because every data you write will be 1 byte to whatever count of byte I think the best way is to use the following method to write data to the memory:
public static void writeMemory(Pointer process, long address, byte[] data)
int size = data.length;
Memory toWrite = new Memory(size);
for(int i = 0; i < size; i++)
toWrite.setByte(i, data[i]);
boolean b = kernel32.WriteProcessMemory(process, address, toWrite, size, null);
You can see some changes. First I changed all address values from int to long, because some addresses are out of range. And with all, i mean all. Not only in writeMemory, but also in readMemory and in your kernel32 Class.
Second I don't use the IntByReference anymore..
To use this method you need to store your data the following way if you would write 4 Byte data:
byte[] values = new byte[]{0x14,0x00,0x00,0x00};
This value would be the number 20. Index 0 will be the lowest byte and index 3 will be the highest byte.
And one more thing I wrote is an method which you can use to calculate your address if you have a baseAddress.
If you restart your program/game your old addresses won't point at the same values of your game. With some research (I use CheatEngine) you can get the baseaddress. This one will alway be the same.
To get from your baseaddress to the dynamic adress you use offsets.
public static long findDynAddy(Pointer process, int[] offsets, long baseAddress)
long pointer = baseAddress;
int size = 4;
Memory pTemp = new Memory(size);
long pointerAddress = 0;
for(int i = 0; i < offsets.length; i++)
if(i == 0)
kernel32.ReadProcessMemory(process, pointer, pTemp, size, null);
pointerAddress = ((pTemp.getInt(0)+offsets[i]));
if(i != offsets.length-1)
kernel32.ReadProcessMemory(process, pointerAddress, pTemp, size, null);
return pointerAddress;
This methods gets a process, an array of offsets (hex-values) and your baseadress and returns the dynamic address.
For Solitaire the following code would give you the address to the score:
long baseAddr = 0x10002AFA8L;
int[] offsets = new int[]{0x50,0x14};
long addr = findDynAddy(process, offsets, baseAddr);
If somebody wants to get the whole code (user32, kernel32 and the cheater) just pm me and I will give you a link. -
Scenario to read from txt-file and create a sales order
Hi,
i have started creating a scenario to read from an txt-file and to create a sales order.
When i activate my scenario, i get the following message :
no scenario step (vBIU) associated for this step for the incoming system (SysId)
When i look into the detailed xml-file i see that all the records are read from the file, but there is no next step to be treated.
Has somebody any idea how this come ?

</Document_Lines>Mike,
you were right, you may not specify the extension of a file.
Another thing i detected is that the loop of my data start with the index 1 instead of 0 !!!
In this scenario, i have to read all the lines of the file and each time i should do a SQL-query,
so that i can use the result to build my sales document.
Do you know if it this is possible or have you any idea how to do this ?
thx,

How to Get Value from a Variable to restrict a Key Figure ?
I am trying to make a query in Query designer, we are running BI7.
I have a user entry veriable on the Fiscal year period, the user will need to enter a period they want the report for, i.e. 07.2008 for July 2008 report and 04.2008 for April 2008 report.
Based on what the user entered as the starting period (in the variable entry), I have to then use that initial value and show the Year to date value (of sales etc) in the next column.
To Clarify, if user entered 07.2008 then all the data from 01.2008 to 07.2008 needs to be in the next column. if user entered 04.2008 then all the data from 01.2008 to 04.2008 should be in the next column.
So to summarise according to my understanding, I want to get the value from a variable and pass it onto another variable to restrict a key firgure (sales amount)...
Can someone please clarify what i need to do here?
Many thanks in advance, points will be awarded accordingly.hi,
please follow the below steps:
1. Create a new varialbe , this variable should be processed by customer exit.
2. In the column section, create a new column and drag the sales key figure, also drag fiscal year period and restrict with the new variable.
3. In the cmod tcode write a customer exit code to extract the value of the user entry and assign it your variable, you can refer to the below code.
WHEN '< New VAR name>'.
IF I_STEP = '2'. "AFTER THE POPUP
LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
WHERE VNAM = '<Fiscal Year Period VAR Name>'.
CLEAR L_S_RANGE.
L_S_RANGE-LOW = LOC_VAR_RANGE-LOW(4).
L_S_RANGE-LOW+4(3) = '001'.
L_S_RANGE-HIGH = LOC_VAR_RANGE-LOW. "LOW E.G. 2001006
L_S_RANGE-SIGN = 'I'.
L_S_RANGE-OPT = 'BT'.
APPEND L_S_RANGE TO E_T_RANGE.
EXIT.
ENDLOOP.
ENDIF.
For ex- if the user enters 008/2008, this code will create as range assign 001/2008 - 008/2008 value to the variable.
hope it helps,

Use a String to get data from a variable?
Hi, I've got a major problem, I need to get data (int []) from a variable, using a String with the name of the variable..
Does anyone know if this is possible?
public class Commands {
private static final int[] deploy_1 = {64,37,73,1};
private static final int[] deploy_2 = {4,167,6,51};
/** Creates a new instance of Commands */
public Commands() {
public int[] get(String name)
// what code here?
}I should be getting the data with
int[] command = Commands.get("deploy_1");
or something like that...
Please help me!
FYI, a hashtable is not a option!
Many thanks, Vikkojava.lang.NoSuchFieldException: deploy_1
at java.lang.Class.getField(Class.java:1507)
at dumb_commandstest.Commands.get(Commands.java:30)
at dumb_commandstest.Main.getData(Main.java:36)
at dumb_commandstest.Main.<init>(Main.java:21)
at dumb_commandstest.Main.main(Main.java:28)
Any ideas why I get a NoSuchFieldException?
deploy_1 does exist.
