BRFplus: Adding Intermediate Data Objects to Expression Workarea

Hi all,
running BRFplus on NW 70105.
I have a Step Sequence Expression with multiple steps calling various Functions. Some of the Functions return intermediate results which must be stored in the context workarea.
I would like to add these Data Objects to the workarea. However the system will not allow me to do this without first adding the Data Objects as signature parameters of the calling Function, even though this does not make sense for intermediate values.
Clicking the "Add existing Data Object" button for the workarea only allows me to add Data Objects which are in the context of the calling Function.
Conversely if a Data Object is deleted from the calling Function's signature, then when checked the Function issues error message "Assigned expression uses Element CUSTOMER/Customer which is not in the context".
Is the requirement to add all Expression workarea Data Objects to the calling Function's signature intended, or is this a bug ? Or is there some other way of doing it that I am missing ??
Thanks & regards,
Grogan

This is a restriction in NW 701. This restriction is removed in NW 702.

Adding new Data Object while migrating from MI 2.5 to NM7.1

Dear All,
      We have a custom MI 2.5 application which we need to migrate to 7.1. While migration, we want to add a newly created data object also in migrated application. But when I try to import MBO model, it is not letting me import new data object. The import finishes successfully. But changes in merepmeta.xml are not done. It creates a file with back up of existing merepmeta.xml i.e. merepmeta.xml.bak and create new merepmeta.xml but it is blank. Am I missing something???
       When I import MBO only with existing data objects (syncbos), it is allowing me perfectly. It is changing the merepmeta.xml accordingly as well without creating backup.
Thanks in advance,
Saptak Kulkarni.

Dear Arjun,
     To answer your questions, previously all the SyncBOs were downloaded independently taking username as the import parameter in getList. (Default values). Yes we can provide the same with 7.1 but we wanted to have some sorts of associations between all SyncBOs.
     So first of all, we changed all the BAPI wrappers of old SyncBOs to download all the data independent of user. Now we created new Data Object to only download user specific data. We associated all other Data Objects on this DO. Created a rule for this data object to only download the sync user instance. We were expecting that whenever a user syncs, a single instance of new user data object will get downloaded and subsequently all other data objects having relationship on user will get downloaded. I hope this is not much confusing.
      Now while we import the MBO model, if we don't import new user data object, then also other data object instance get downloaded and fortunately properly filtered. We don't receive any kind of error over here.
      The new data object is not used anywhere in the application. The associations are in new data object and not in the older one. New data object is the leading one wherein others follow.
      Not a single instance is getting dropped for other Data Objects.
      The xml is blank only when we try to import the new Data Object and correctly it gives an error as expected when I try to deploy the application.
Thanks in advance,
Saptak.

Adding an "x" number of Days to Date Object

Hi guys,
What I would like to is lets say you have a date object, looking for method/way of adding or subtracting X amount of days from that object.
This is because I have a list of dates that I would like to follow up on eachother like :
1/7/06-5/7/06(Date EndDate)
(Date EndDate + 1) i.e 2/7/06 - 31/7/06
Thanks in advance

For anyone that has the same problem this is how I got it working.
Thanks for the help in the post.
     static Date addDaysToDate(Date startMonth, int days)
          Calendar c = Calendar.getInstance();
          c.setTime(startMonth);
          c.add(Calendar.DATE, days);
          startMonth = c.getTime();
          return startMonth;
     }

Adding days to a date object

I am retreiving a date field from the database.
i am retrieving that with getDate() method on the result set object.
that is am retrieving as java.sql.Date object.
on that date object i have to add 30 days and store it back in the
database as a date field in database.
How should i go about handling this problem.
suppose
java.sql.Date newDate=rs.getDate(1);
on this newDate how can i add 30 days and store it back to the database.
Plz help me out guyz.
Thanks.

wud the setting to a particuale date means setting to
the date i retrieved from the database.
How to set for a particular date.We have setTime()
method in Calendar.
but that takes util.Date object.Then do i have to
convert the sql.Date object into a util.Date object.A java.sql.Date IS-A java.util.Date.
(There's no such thing as a sql.Date or a util.Date unless you have a different API than the rest of us.)

Code for Custom Business Object and Adding/Updating Data

Hi,
I would like to update/insert data thru Custom Business Object to sql Server.Pls let me know is it possible in MSA.If yes I would appreciate if you can share the code/Process in this forum.
Thanks and Regds
Harish

Depending on what data you update you need to do the following:
If updating SAP tables or customer tables which are an extension of a SAP object like business partner, material, activity or similar:
1. Create the extension of the data object via the easy enhancement workbench (EEWB). This will also create mapping functionality from MSA to CRM Server and extend the BDocs.
2. Go to the BDoc modeler. Find the sBDoc for data exchange (type Write BDoc), that contains your object and check whether the new segment is there.
3. In the Mobile Application Studio (MAS) you can now create a custom business object related to the standard sBDoc mentioned in 2 which is mapped to the new segment. This way the data exchange happens together with the main object
4. Drag & drop the fields of the new BO to a new tile, and link that tile to the existing main object in the UI via the appropriate relation.
If you would create a new business object / BDoc for a set of attributes belonging to a main object and not use an extension of the existing BDoc then the data would get its own flow and when replicating it would not come together with the main data. This can lead to data inconsistencies and in surplus effort administrating this data.
If you have your own objects not related to a SAP object, you can do it the following way:
1. Create your own table(s)
2. Create a Write sBDoc on the table(s)
3. Create BO's on each BDoc segment / table
4. (as above)
Hope this helps,
Kai

What is the best way to add a day to a Date object?

I have come across numerous examples on adding a day to the CURRENT date, using the Calendar object. However, what I need to do is to add a day to a Date variable.
Can someone tell me how to do that? I tried to set the value of my Date variable into the Calendar object, but, it appears that for the current JAVA version, they have deprecated the getYear(), getMonth() and getDay() methods for the Date class.
Really appreciate your suggestions.
Thank you in advance,
SiowLing

I haven't seen the OP express a concern over how to create/obtain the Date object (he could be using "new Date()" given the emphasis on "CURRENT"). Milliseconds is fine too if that's what you have (for example from a java.sql.Date).
So the way to add a day to a Date object (the OPs original question) is to:
- set the Date on a Calendar using setTime
- add 1 to the DATE field of the calendar
- get the Date from the Calendar using getTime
Obviously you're right if the OP doesn't have Date object to start with, but just the "numbers" for year, month, day.

Create custom data object in BAM for a BPM project

I'm working with 11g (11.1.1.3)
I have created (via JDEV) a simple BPM process and I have inserted 3 business measurement
I have set ( as indicated in oracle documentation and in "Getting started") in BPM project :
project preference --> data target :
- enable BAM cheked
- BAM adapter JNDI name : eis/bam/soap
- in BATCH no cheked
- data object path : /Samples/Monitor Express
I have defined new data object in BAM --> Architect
I have renamed the default data object template in BI_DEFAULT_MyProject_MyProcess (is BI_DEFAULT_businessIndicator_businessIndicator)
I have added in layout my measurement; I have inserted in the bottom METRIC_myBI1, METRIC_myBI2, METRIC_myBI3 ( are METRIC_Segnalazione METRIC_nSegnalazioni METRIC_misura) of the same type indicated in BPM process
I have create few istance of the process, but :
- in the BI_DEFAULT_MyProject_MyProcess content there isn't anything
- in the default data objects ( COUNTER, INTERVAL, COMPONENT) I find the data of my process
please help me!!
I do not know what else to do

Message class as result data object

hello brf+ users,
is it possible to use as Result data object in a Case expression a message from a custom message class?
thanks
danilo

thanks Carsten,
my requirement can be simplified in
IF FISCAL CODE
equals to " " then "001" ENTRY MISSING is returned
otherwise "000" check ok is returned.
where 000,001 are domain values of an element (MESSAGE RESULT).
can i use the message class as result? is there a way to anchor the result to the message class?
thanks
danilo

Adding new data row(s) to DataGrid control

My requirement is to provide the ability to add a new row to
the datagrid when tabbed out of the (last cell of the last row of
the datagrid. I have made my datagrid editable and in the
'itemEditEnd' handler I am adding a new object (with empty values)
to the data provider for the Grid and setting focus to the Grid and
then setting the new row index as the Selected Index for the Grid.
None of this activating itemEditor for the first cell of the new
row.
I have seen somewhere that dispatching the itemEditBeginning
will do this for me. But not sure how to do this. Appreciate if can
point me to a sample woring example.

Perfect - Have been looking for a solution since few days.
You just made my day. Thank you so much.

TableSorter errors when adding new data

so here is the deal:
I am using the TableSorter.java helper class with DefaultTableModel
from: http://java.sun.com/docs/books/tutorial/uiswing/components/table.html
It works great when the data is static and I get it for the first time. however, occationally, when adding new data I get a NullPointerException error.
in use:
DefaultTableModel.addRow()
DefaultTableModel.removeRow() and
DefaultTableModel.insertRow() methods.

* TableSorter is a decorator for TableModels; adding sorting
* functionality to a supplied TableModel. TableSorter does
* not store or copy the data in its TableModel; instead it maintains
* a map from the row indexes of the view to the row indexes of the
* model. As requests are made of the sorter (like getValueAt(row, col))
* they are passed to the underlying model after the row numbers
* have been translated via the internal mapping array. This way,
* the TableSorter appears to hold another copy of the table
* with the rows in a different order.
* 
* TableSorter registers itself as a listener to the underlying model,
* just as the JTable itself would. Events recieved from the model
* are examined, sometimes manipulated (typically widened), and then
* passed on to the TableSorter's listeners (typically the JTable).
* If a change to the model has invalidated the order of TableSorter's
* rows, a note of this is made and the sorter will resort the
* rows the next time a value is requested.
* 
* When the tableHeader property is set, either by using the
* setTableHeader() method or the two argument constructor, the
* table header may be used as a complete UI for TableSorter.
* The default renderer of the tableHeader is decorated with a renderer
* that indicates the sorting status of each column. In addition,
* a mouse listener is installed with the following behavior:
* <ul>
* <li>
* Mouse-click: Clears the sorting status of all other columns
* and advances the sorting status of that column through three
* values: {NOT_SORTED, ASCENDING, DESCENDING} (then back to
* NOT_SORTED again).
* <li>
* SHIFT-mouse-click: Clears the sorting status of all other columns
* and cycles the sorting status of the column through the same
* three values, in the opposite order: {NOT_SORTED, DESCENDING, ASCENDING}.
* <li>
* CONTROL-mouse-click and CONTROL-SHIFT-mouse-click: as above except
* that the changes to the column do not cancel the statuses of columns
* that are already sorting - giving a way to initiate a compound
* sort.
* </ul>
* 
* This is a long overdue rewrite of a class of the same name that
* first appeared in the swing table demos in 1997.

The code you posted doesn't help us at all. Its just a duplicate of the code from the tutorial. The custom code is what you have written. For example do you update the TableModel from the Event Thread? Do you update the SortModel or the DefaultTableModel? If you actually provide your test code and somebody has already downloaded the sort classes, then maybe they will test your code against the classes. But I doubt if people will download the sort classes and create a test program just to see if they can duplicate your results (at least I know I'm not about to).

I made a new Date object

See, here's the thing with dates in java, the way i see it. We used to have Date, but Date wasn't international so we got Calendar. But some things, like SimpleDateFormat, still expect java.util.Date. java.sql.Date is out there somewhere, too. None of them have direct support for date differences (i.e. dateA - dateB = 8 days, or whatever). Now you're probably reading this thinking "Java supports all of this" and you're right. Calendar has a getTime method that returns a Date, and i can just pass THAT to SimpleDateFormat. With a little math, getTimeInMillis can be used to find the difference in two Calendars. But i got to thinking, "There should only be one Date object i need to think about," and since i don't ever have enough to do at work i put one together. I don't know if any of you are going to care enough to use it, mostly i'm just looking for advice on features i should add to it, inefficiencies in the design, stuff that's hard to understand, or whatever.

The reason Callendar is so complicated is that it is trying to solve a very complicated problem.
You don't appear to support leap seconds (of which there can be upto 2 in any time interval)
http://www.timeanddate.com/time/leapseconds.html
Some of your code will not work for large dates very well (seems to iterate over the years). Try using your date class for astronomical or geological calculations. them big numbers will make your code slow at the moment.
You don't seem to support timezones or transitory offsets (BST vs GMT). You most definately don't handle changes to timezone offsets that have occured in the past or historical daylight savings time offsets (they have not always been the same)
The difference between two calendars is a "duration" a duration means nothing unless it is applied to a caledar/date (although you may be able to get away with it if the duration is always stored in millis)

Difference b/w DATA TYPE and DATA OBJECT & differences b/w TYPE and LIKE

hai
can any one say the differences between Data type and Data Object.
And also differences between TYPE and LIKE
thanks
Gani

hi,
_Data Types and Data Objects_
      Programs work with local program data that is, with byte sequences in the working memory. Byte sequences that belong together are called fields and are characterized by a length, an identity (name), and as a further attribute by a data type. All programming languages have a concept that describes how the contents of a field are interpreted according to the data type.
      In the ABAP type concept, fields are called data objects. Each data object is thus an instance of an abstract data type. There are separate name spaces for data objects and data types. This means that a name can be the name of a data object as well as the name of a data type simultaneously.
Data Types
   As well as occurring as attributes of a data object, data types can also be defined independently. You can then use them later on in conjunction with a data object. The definition of a user-defined data type is based on a set of predefined elementary data types. You can define data types either locally in the declaration part of a program using the TYPESstatement) or globally in the ABAP Dictionary. You can use your own data types to declare data objects or to check the types of parameters in generic operations.
     All programming languages distinguish between various types of data with various uses, such as .. type data for storing or displaying values and numerical data for calculations. The attributes in question are described using data types. You can define, for example, how data is stored in the repository, and how the ABAP statements work with the data.
Data types can be divided into elementary, reference, and complex types.
a. Elementary Types
These are data types of fixed or variable length that are not made up of other types.
The difference between variable length data types and fixed length data types is that the length and the memory space required by data objects of variable length data types can change dynamically during runtime, and that these data types cannot be defined irreversibly while the data object is being declared.
Predefined and User-Defined Elementary Data Types
You can also define your own elementary data types in ABAP using the TYPES statement. You base these on the predefined data types. This determines all of the technical attributes of the new data type. For example, you could define a data type P_2 with two decimal places, based on the predefined data type P. You could then use this new type in your data declarations.
b. Reference Types
Reference types are deep data types that describe reference variables, that is, data objects that contain references. A reference variable can be defined as a component of a complex data object such as a structure or internal table as well as a single field.
c. Complex Data Types
Complex data types are made up of other data types. A distinction is made here between structured types and table types.
Data Objects
      Data objects are the physical units with which ABAP statements work at runtime. The contents of a data object occupy memory space in the program. ABAP statements access these contents by addressing the name of the data object and interpret them according to the data type.. For example, statements can write the contents of data objects in lists or in the database, they can pass them to and receive them from routines, they can change them by assigning new values, and they can compare them in logical expressions.
       Each ABAP data object has a set of technical attributes, which are fully defined at all times when an ABAP program is running (field length, number of decimal places, and data type). You declare data objects either statically in the declaration part of an ABAP program (the most important statement for this is DATA), or dynamically at runtime (for example, when you call procedures). As well as fields in the memory area of the program, the program also treats literals like data objects.
        A data object is a part of the repository whose content can be addressed and interpreted by the program. All data objects must be declared in the ABAP program and are not persistent, meaning that they only exist while the program is being executed. Before you can process persistent data (such as data from a database table or from a sequential file), you must read it into data objects first. Conversely, if you want to retain the contents of a data object beyond the end of the program, you must save it in a persistent form.
Declaring Data Objects
      Apart from the interface parameters of procedures, you declare all of the data objects in an ABAP program or procedure in its declaration part. These declarative statements establish the data type of the object, along with any missing technical attributes. This takes place before the program is actually executed. The technical attributes can then be queried while the program is running.
     The interface parameters of procedures are generated as local data objects, but only when the procedure is actually called. You can define the technical attributes of the interface parameters in the procedure itself. If you do not, they adopt the attributes of the parameters from which they receive their values.
ABAP contains the following kinds of data objects:
a. Literals
Literals are not created by declarative statements. Instead, they exist in the program source code. Like all data objects, they have fixed technical attributes (field length, number of decimal places, data type), but no name. They are therefore referred to as unnamed data objects.
b. Named Data Objects
Data objects that have a name that you can use to address the ABAP program are known as named objects. These can be objects of various types, including text symbols, variables and constants.
Text symbols are pointers to texts in the text pool of the ABAP program. When the program starts, the corresponding data objects are generated from the texts stored in the text pool. They can be addressed using the name of the text symbol.
Variables are data objects whose contents can be changed using ABAP statements. You declare variables using the DATA, CLASS-DATA, STATICS, PARAMETERS, SELECT-OPTIONS, and RANGESstatements.
Constants are data objects whose contents cannot be changed. You declare constants using the CONSTANTSstatement.
c. Anonymous Data Objects
Data objects that cannot be addressed using a name are known as anonymous data objects. They are created using the CREATE DATAstatement and can be addressed using reference variables.
d. System-Defined Data Objects
System-defined data objects do not have to be declared explicitly - they are always available at runtime.
e. Interface Work Areas
Interface work areas are special variables that serve as interfaces between programs, screens, and logical databases. You declare interface work areas using the TABLES and NODESstatements.
What is the difference between Type and Like?
Answer1:
TYPE, you assign datatype directly to the data object while declaring.
LIKE,you assign the datatype of another object to the declaring data object. The datatype is referenced indirectly.
Answer2:
Type is a keyword used to refer to a data type whereas Like is a keyword used to copy the existing properties of already existing data object.
Answer3:
type refers the existing data type
like refers the existing data object

Add/Remove data object from dataset

Hello,
I was working out a way to add and remove data from a dataset
on the fly and could not figure out any built in methods to do
this.
As I have decided to include spry in my project I like to try
and utilise as much as of its code as possible since it is
complicated to explain I have created a simple example – a
colour picker! (thought it might be more interesting…) of
what I am trying to achieve at
http://www.freshfresh.co.uk/spry/
- if you have a go on this and maybe look at the source code (all
the JS is embedded in HTML there are no modifications to other the
other core files). I have only used spry effects etc, including the
‘accordion’ – which I have become quite attached
to, it is really good for condensing pages down.
You will see I am using the setDataFromDoc method to create
the dataset – I tried the .data = myArrayOfData; .dataHash =
hashTable; method i.e. creating from an object rather than array
but it did’nt seem to play ball with the
addDataChangedObserver method – it did’nt update itself
each time it was modified (I am sorry I cannot remember exactly
what I did – but I tried all kinds of ways…). I stuck
with the string method because it worked - each time my new dataset
changed it updated itself on the screen (you will have to have a
look to understand.....sorry!!), but I would be interested to know
how such a thing could be implemented using the object route if you
believe this would be more efficient.
My second question is more simple – is there a shorter
way to add and remove a data object from a dataset? – as you
can see from the source code I have effectively created an
‘interface’ to do these tasks…. I could’nt
work out whether these methods are already built in. Maybe they
are?
Third question is… to extract a data object from a
dataset I use the .dataHash[the_row_id] method – is this the
right thing to do or could it lead to complications… that is
using methods that might supposedly be private?
Fourth question (observation really) – whilst creating
that colour picker example I went over board with my datasets and
loaded in several palettes some of which had over 1000 elements or
data objects. Which inevitably was very slow (on my computer
anyway) – but it got me thinking about trimming the contents
of my spry regions for better performance. I am I right in thinking
that the less HTML etc that there is in a spry region the quicker
SPRY will process it. For example say you had spry repeat with an
image tag in with some onclick, onmousover, onmouseout, style
attributes etc and compare this to a spry repeat with a simple
image with minimal attributes set. I suppose what I am trying to
say is – does spry ‘store’ all the contents of
each spry region somewhere? Or does it just process it and leave it
to the browser dom?
Fifth observation.... I find it really difficult to explain
computer technicalities in writing. It must be tough reading these
posts.... I know I find it difficult sometimes when dealing with
written end user feedback!
Andrew

Just clarifying my questions a bit further....
I found some old code regarding question 1 by using the
object method I mean something like this...
var mySwatches = [{'@hex':'ff0000'},{'@hex':'00ff00'}];
var hashTable = [];
function createDs(){
for (var i = 0; i < mySwatches.length; i++)
mySwatches
.ds_RowID = i;
hashTable = mySwatches
dsMySwatches.data = mySwatches;
dsMySwatches.dataHash = hashTable;
dsMySwatches.loadData();
i.e. not writing out a whole XML string string as the online
example does. When using this way I did'nt seem to be able to get
the HTML to refresh. I tried using [
Spry.Data.updateRegion('mydata'); ] after recreating the dataset I
also tried adding an [ .addDataChangedObserver ] (like in the
string example) amongst numerous other ways but it just would not
work like the string way. - Maybe I did something wrong somewhere.
In question 3 I refer to the [ .hash ] method .... its not a
'method' its a 'property' - my question should read - is it ok to
access private properties (from a browser campatiblity/security
point of view) that do not have specific methods to gain access to
them. I suppose it does'nt really matter with JS...
In question 4 I mention minimising the amount of code in a
spry region to speed it up. A clearer example of this might be for
example - a gallery with lots of images. As we know there will be a
slight delay as SPRY writes all the html so to speed up that intial
write I strip out all the image attributes such as onlclick do
this, onmouse over do that... and add these after the images have
loaded using a seperate function similar to my
fillSwatches(ds,prefix) function in my online colorpicker example.
I suppose it like a 2 tier processing of all the data. SPRY does
the intial display writing to get everything in place and then
another pass is made over to add any further functionality
adjustments etc. I am still not sure if that makes any sense!
***edit
Also on the subject of speed and the application as a whole
i.e. including my PHP - In one example I was creating I ended up
with an XML structure where each node has over 14 attributes i.e.
<somenode att1=”x” ……..
att14=”z”/> - as the file grew it obviously took
longer to process particularly on the server side, i.e. added all
those attributes just slowed it all down. So I did
this…… <somenode att1=”x:y:z” /> i.e
condensed selected attributes into a string that I could explode
later on.
Obviously this limits SPRYS ability to access the attributes
using the {attr} syntax. I had to create a function to explode the
array and do the ‘necessary’ on a second pass over the
data – this works ok for me. But its interesting that in this
particular case the server could not refresh the XML in an
acceptable time without doing this – just thought that might
be interesting to you. I suppose technically what I am doing is
abusing the concept of an XML structure and simply using it as a
‘carrier’ to feed my application …. Which I
suppose is where JSON comes in…. which is a bit more compact
and maybe faster to manipulate on both the server and client side
– I don’t really know, I have never used it –
just throwing ideas around!!

Oracle BPM and JMS Queue: How to associate data from Map Messages to Process Data Objects?

Good Day!
I'm currently working on a project wherein it tries to get data from a JMSqueue Map Message being populated by CEP.
After CEP pushes some data in the JMSqueue. I have BPM configured with a JMS adapter to look up whether there are any messages to be processed upon.
Inside BPM, I want to know how can I correlate the data from the Map Message to my Process Data Object.
For example, If I have a Map Object wherein it has 3 attributes:
FirstName:String
LastName:String
Age:int
What is the expression I need to use inside Oracle BPM Data Association screen in order to map the data from the Map Messages into my process data objects?
Thanks!
Regards,
Jeff

Any ideas? Thanks!

RE: DataField, update underlying data via TOOL,Express

does it work if you mix the "CopyfromClipboard" method with the "PlaceValueinDisplayedField" ?
If this is not the correct solution to you problem, could you please specify "where" it does not work ?

Subject: DataField, update underlying data via TOOL, Express
In TOOL code we PasteText() into a DataField, but the underlying data
object does not get updated until the user interacts with the GUI.
That causes problems if we need to use the underlying data object's
value immediately after the paste. How can we:
force an update of the underlying data object and
ensure that the update goes through before our method call returns,
i.e., ensure that if the update is via Forte events, those events
are handled before returning.
The context is a calendar lookup button that pastes into an adjoining
DataField.

Well, I think I have answered my own question, but I will leave it here in case anyone else has the same problem.
So, as far as I have been able to track down, it all went wrong when I was running through the connection wizard.
Under the section titled "Creating the Data Source" is describes how to find your database file and create the appropriate connection string. However, on my version of VS Express 2010 . It offered me a prompts , saying something like, "would you like to
move this database file into the application directory and change the connection string" this sounded very sensible to me, so I said yes.
All proceeded accordingly. And the database file now appeared in the solution explorer.
The app config file said that the connection string was
Data Source=|DataDirectory|\Database1.sdf"
I presumed this would be interpreted correctly by the rest of the app, as it was generated by VS.
But it didn't, what I cannot understand is how no error was generated. And data seemed to pull
into the bound controls.
But I have been testing it for a while now. and it seems that if I manually override the config file with the actual directory where the file exists , then there is not a problem. Data is retained in the file
This is more of a VB.net question, but I couldn't find it in the drop down. I will try and move it there now
Thanks guys for your patience.
p.s. RSingh , the code I posted above did come from the SaveItem_Click event
handler
