How to response the value change of slide bar only after mouse released

Hi, all
When I used the slide bar to control my device, I response the value change of slide bar and set the new value to my device. But it will generate response constantly when I use the mouse to drag the pointer, which is not my wanted. I just need to response only after the mouse released. How can I implement this function?
Hope your suggestion, thanks a lot.
Solved!

No, not if you use the right event under "Mouse".

[BC4J] how to revert the value in an entity based table after exception

Hi,
I'm running BC4J 9.0.4.3.
I have a JTable with an AttributeListBinding to an entity based ViewObject.
I added an Validation to a setter method of an entity which throws a RuntimeException.
THe Framework correctly displays the errormessage, but the Table keeps the new entered invalid value.
What I want is that the value displayed in the table is revertet to tha last entry.
How can I do that?
bye

Hi Peter
Thank you for your suggestions, both of them are interesting but unfortunately they do not solve my problem, or at least I don’t know how.
I will try to better explain my problem
I have te table DBTABLE and another related table called DBDATES with colums(C1,DT1,DT2,TARGET) where I record periods of time and desired target. For instance my DBDATES table could have the following records
ONE; 01/01/2012; 31/01/2012; 100
ONE; 01/02/2012; 29/02/2012; 90
ONE; 01/03/2012; 31/03/2012; 95
TWO; 01/01/2012; 31/01/2012; 140
Exist a FK between both tables in the C1 column.
I have created an EO for the table DBTABLE with the tree persistent attributes (C1, N1, D1) an transient attribute (T1). The (C1,D1) is my DB primary key.
When I create a new record in the DBTABLE and based in the actual date I need to query the DBDATES table to check which is my TARGET and the valid target dates. For Instance if a record for person ONE is created on February 12, my TARGET is 90 from 01/02/2012 to 29/02/2012.
At the same moment I need to check the total amount of items record to the person ONE during the full target period.
Select sum(N1)
From DBTABLE
Where D1 between V2 and V3
And C1= V1;
Bind variables:
V1 = ‘ONE’;
V2 = ‘01/10/2012’ – queried from DBDATES
V3 = ‘03/10/201’ – queried from DBDATES
In resume, for a determined person when I create a new record in the DBTABLE I need to know their target for the actual period and how much as been record until now.
I don't know if is possible to solve this without using the View Objects, because I need to query the DBTABLE for a time frame and with bind variables.
Thank you in advance for your help.

How can I fire an event case on the value change of an indicator, or a network variable?

Hi! I have an event structure setup to look for a value change of an indicator on the front panel. The indicator is updated by the value of a boolean network-published shared variable through a seperate parallel loop that is polling all of the network-published shared variables. The event, however, does not fire when the indicator changes value. I have switched the indicator to a control and tested it with user interaction and that works just fine.
I want to use the event structure space for my code exectution because it seems logical that that is where it would go, and it will help keep my block diagram tity. The code is also something I would like executed with the front pannel temperarily disabled. I would rather not have the code in my network-variable polling loop because again the tity issue. I would also rather not use a notification VI wired to an independent loop for this particular code.
Is there a way to have an event structure fire an event with the value change of an indicator, or a network variable directly?
Thanks for your input.

Thanks for the reply.
I went about things a little differently, but got them to work so..... . It really was not my desire to have a boolean indicator on the front panel. As previously stated, my ultimate goal was to have an event fire on the change of a network variable, which I had to poll for anyway but that is tucked away in a section where I am handling all my network variables. I ended up using that Create User Event, Register User Event, and Generate User Event SubVIs to handle the task.
I've read the help for all of those SubVI's and it is not entirely clear to me if the event fires every time the "Generate User Event" receives some inputs, or if it only fires when the value changes. I could do a test to find out. It wouldn't be too difficult to add a shift register or a feedback node and place the Generate User Event in a case structure so that it is only fired when the input changes state.

How to get the values of the objects inside an object??

Hi,
I am trying to write code to display name and memory usage of all session attributes, in a recursive way.
I suppose reflection is needed here, but I cant figure out how to get the values of the objects inside an object...
private void handleIt(String attributeName, Object attributeValue) {
     boolean isPrimitiveOrNull = ((null == attributeValue) ||
          (attributeValue.getClass().isPrimitive()));
     if (isPrimitiveOrNull) {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "}");
     } else {
          sb.append("{" + attributeName + ":" + sizeOf(attributeValue) + "{");
          Field[] fields = attributeValue.getClass().getDeclaredFields();
          int lim = fields.length;
          String name;
          Object value = null;
          for (int i = 0; i < lim; i++) {
               name = fields.getName();
               //LOOK AT THIS LINE: !!!!!!!!!!!!!!!!!!!!!!!!!!!
               value = fields[i].get(obj); //I don´t know what 'obj' should be??
               handleIt(name, value);
          sb.append("}");
Any suggestions will be greatly appreciated...

I realized that massive int objects called MAX_VALUE, MIN_VALUE and SIZE where causing the StackOverflow, so I removed them from the analysis.
This is the resultant code. But I think it isnt accurate in calculating the real size of objects being got using reflexion.
Do you or somebody have any more suggestions?

How to get the value entered in input enabled field of a list output?

Hi all,
I am developing a program to display list with two input enabled fields . After users enetered the values into these fields I need to do some calculations based on these values and modify the value of another field in the list.
But i couldn't have an idea how to read the values after users enter into these fields.
Please help me on solving this problem? If possible please provide the sample code.
Thanks,
Aravind.

You can enable disable screen fields in at selection screen output event.
And by using loop at screen.
And for changing the values you can do in initialization event.
I Hope you are doing these in Reports.

How to capture the values given in SSC1 transcation?

Hello All,
Can anyone suggest me, how to capture the values given in SSC1 transaction?

Hello Clemens Li,
Requirement: Integration of SAP Appointment Calendar with Gmail Calendar
If I create an appointment in SSC1 transaction, it will appear in SAP Appointment calendar. The same thing should get updated in Gmail calendar of SAP user and also in the guest Gmail calendar if exists in appointment.
So, I have to capture the input values given in SSC1 transaction while creating an appointment in SAP and try to export those values to web services using some function module. Sending those values to web services completes my task.
Means, if I create an appointment in SAP, at the same time, the values which I gave must get exported to some object. So that I can send them to web services.
But my actual problem is with capturing the input values given to SSC1 transaction.
How can I get those values out to some internal table?
Another one is, I did not found any BADI to enhance SSC1 transaction so that I can include my code there.
If you know any enhancements in SSC1, please let me know.
If you want any more clarification, please let me know.
Thanks for the response

How to read the value of Non-Linear Transformer ?

Hi there !
I know that we could make "modified" transformer for special purpose (with Vsec=5V for example). But, instead of make a new transformer, it might be more easier if we could know how to read the value of those transformer. For example, NLT_PQ_4_120 or NLT_PQ_4_10. To be narrowed, what is the meaning of 4_120 and 4_10 ?
Anyone ?

To understand the models you mentioned you need to understand XSPICE. I suggest you use the virtual transformer instead because it is easy to change the turn ratio, you can double clicking on the component and enter what ever ratio you want.

Webdynpro : How to SKIP the values of the Model Node.

Hi
i imported a WSDL into my WDJ application.
where on context mapping, i mapped the MODEL with my CONTROLLER.
I would like to SKIP couple of Attributes and Model node
In WEBSERVICE navigator, i have the check box as SKIP, so using that i can skip in Navigator ,
But how to do the same in WEBDYNPRO Coding.
Say for Example
Context
----------ModelNode1
----------ModelNode2
----------ModelNode3
----------======ModelAttribute1      NULL
----------======ModelAttribute2      SKIP
----------======ModelAttribute3      SKIP
i know how to set the value if it need to set it to null
wdcontext.nodelModelNode3.currentModelNode3element.setModelAttribute1("null")
similaraly can anyone tell me how to set the SKIP for other 2 attributes......
Thanks

Hi Chintan
Thanks for your response....
fine ... i understood your solution....
but , my problem goes and makes me dizzzy
i have 10 mandatory filed in my Webservice..
i passed all the 10 mandatoy fileds and get perfect Response In WEBSERVICE Navigator....
i tried passing the same value via WDJ application as show below
since i have a node element with cardinalith 0..n
I set the value those i passed in Webservice Navigator.....
wdContext.nodeRequest_getSubmitRequest().
                 nodeRequestDetails().nodeRoles().invalidate();
     IPrivateOne_AppView.IRolesElement RoleE = wdContext.createRolesElement(new ComplexType_RoleData());
     RoleE.setRoleId("BASIC");
     RoleE.setSysId("R3");
     wdContext.nodeRequest_getSubmitRequest().
               nodeRequestDetails().nodeRoles().addElement(RoleE);
But Here ,I get a Error Message Saying :Error in Submiting Request : No role seleced for the request.
so , i even checked whether the node is populated with rite value by printing them after executing the WSDL.
     wdContext.currentRequest_getSubmitRequestElement().modelObject().execute();
          MsgManger.reportSuccess( "After Push_execute_WSDL");
MsgManger.reportSuccess( " COntroller getRoleId -- "+wdContext.nodeRequest_getSubmitRequest()
                    .nodeRequestDetails().nodeRoles().currentRolesElement().getRoleId().toString());
          MsgManger.reportSuccess( " COntroller getSysId -- "+wdContext.nodeRequest_getSubmitRequest()
                    .nodeRequestDetails().nodeRoles().currentRolesElement().getSysId().toString());
Output
After Push_execute_WSDL
COntroller getRoleId -- BASIC
COntroller getSysId -- R3
Kindly let me know wat could be wrong........
The MOST wired thing is
if i didnt set and Role , SysId in webservice navigator , then Error thrown at Webservice Navigator is
Error in Submiting Request : RoleId is mandatory,SysId is mandatory null
on following same thing , if i didnt set Role and SysID in WebDynpro then, i get error as
Error in Submiting Request : No role seleced for the request.
How is this possible....
any help on this would be appreciated...
Thanks

How to get the values from popup window to mainwindow

HI all,
   I want to get the details from popup window.
      i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
   now i am able to display popup window with values.How to get the values from popup window now.
   I can anybody explain me clearly.
Thanks&Regards
kranthi

Hi Kranthi,
Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

Uday

How to get the value from databank

Hi,
How to get the value from databank? and how to set the same value to visual script object?
thanks,
ra

Hi,
You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
Thanks

Thanks in Advance,

Hi Hanimi,
1. You need to extend the VO, add a new Attribute.
2. In VORowImpl of the extended VO, you can find the getter for your new attribute (example getItem())
3. In this getter method you can write some code like:
if("ABC".equals(getItemDescription())
return "XYZ" ;
