Changing type of process during runtime

hi to all/Mike/Antony
is there anyway to change a sync process to async during runtime?
thnx in advance
KAM

hi
sorry for making confusion by putting a (little) wrong question because of being in a hurry...
it was supposed to be that " is there anyway to change the type of the process from async to sync after executing the process"
i m sorry for taking ur time by putting a wrong question!
actually i made a sync process of "HelloWorld " but mistakenly declared its type as "async" and it did not generate the required output, because it was an async process and i was treating it as a sync one!
thanks for ur interest. i'll write, as i find the solution.

Change XSD / XML dataset during runtime and display texts in field explorer

Hi there,
I am changing the datasource of a report during runtime. Afterwards, I would like to change the texts of the fields appearing in the field explorer.
I tried:
CrystalDecisions.ReportAppServer.DataDefModel.XMLDataSetClass xmlDS =
new CrystalDecisions.ReportAppServer.DataDefModel.XMLDataSetClass();
byte[] xmlContent = reportContent.getXmlContent();
byte[] xsdContent = reportContent.getXsdContent();
CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray xmlData =
new CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray();
CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray xsdData =
new CrystalDecisions.ReportAppServer.CommonObjectModel.ByteArray();
xmlData.ByteArray = xmlContent;
xmlDS.XMLData = xmlData;
xsdData.ByteArray = xsdContent;
xmlDS.XMLSchema = xsdData;
rasDoc.DatabaseController.SetDataSource(xmlDS, "", "");
rasDoc.Database.Tables[0].Description = "POMMES";
for (int i = 0; i < rasDoc.DatabaseController.Database.Tables[0].DataFields.Count; i++)
rasDoc.Database.Tables[0].DataFields.Name = "TEST";
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.Name);
rasDoc.Database.Tables[0].DataFields.HeadingText = "HOORAY";
rasDoc.Database.Tables[0].DataFields.Description = "NOPE";
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.Description);
MessageBox.Show(rasDoc.Database.Tables[0].DataFields.HeadingText);
When running this, the message boxes include the right strings I set before but when this is done, the filed explorer still shows no changes. What am I doing wrong?
Also, I would like to change the field texts that are displayed in the field explorer. How can this be done?
Thanks,
Pascal

Also, I do not understand why I am not able to change the display of the fields in the filed explorer.
This coding does not change a bit, but why??
//preparation
string tableName = reportDataSet.Tables[0].TableName;
 // Get the table definition exactly like the definition of my own dataset.
 CrystalDecisions.ReportAppServer.DataDefModel.Table table = GetTable(tableName);
 table.ConnectionInfo = connectionInfo;
 //delete all existing tables if there are any
 foreach (CrystalDecisions.ReportAppServer.DataDefModel.Table oldTable in rasDoc.DatabaseController.Database.Tables)
 rasDoc.DatabaseController.RemoveTable(oldTable.Name);
 //add my new table with the IDs of the XSD
 rasDoc.DatabaseController.AddTable(table, null);
 //now I want to change the displayed fields texts
 CrystalDecisions.ReportAppServer.DataDefModel.Tables modifyTables =
 rasDoc.DatabaseController.Database.Tables;
 CrystalDecisions.ReportAppServer.DataDefModel.Table myTable =
 (CrystalDecisions.ReportAppServer.DataDefModel.Table)modifyTables[0];
 Fields fields = myTable.DataFields;
 for (int i = 0; i < fields.Count; i++)
 ISCRField field = fields;
 ResultFieldController resultFieldController =
 rasDoc.DataDefController.ResultFieldController;
 try
 resultFieldController.Remove(field);
 string sText = "";
 sText = "Bäschreibung" + i.ToString();
 field.Description = new string(sText.ToCharArray());
 sText = "Häding" + i.ToString();
 field.HeadingText = new string(sText.ToCharArray());
 //sText = "Näme" + i.ToString();
 //field.Name = new string(sText.ToCharArray());
 resultFieldController.Add(-1, field);
 catch (Exception exp)
 MessageBox.Show(exp.Message);
I am completely stuck.
Thanks for any help.

Change Chart background color during runtime

I want to change the background color of my chart during runtime.
I can set and read-out the color with a property node but the apperance on the frontpanel is not changing.
After stopping the VI the chart suddenly gets updated.
Please check my VI attached.
Do someone knows a workaround?

Hello Robert,
another option would be to place (for example) a vertical smooth box behind the chart and change the color of it.
See my attachment.
Best regards

Change webdynpro element position during runtime.

Hi Experts,
For one SAP standard screen there are 4 input field in the webdynpro view. Is it possible to change the position/order of these standard elements by enhancement or during run time?
Thanks

Hi Srinivas
Yes, this is possible !
You can create a component configuration(CC) from the context menu of the related Web Dynpro Component (Create/Change Configuration).
Enter an id for new CC eg., ZTEST and click Create.
In the next screen, click on the last tab labeled Web Dynpro Built-In. Hierarchy of UI elements will be displayed. Click on the Container UI element that contains your 4 input fields and then click on Re-sort link that appears on the right hand side. Now you can sort the input fields. Save your Comp Config. Run the standard WD application using newly created comp config by passing parameter 'ZTEST' in the URL.
Hope this helps.

A question about how to change a button in a JPanel during runtime

I am a beginner of GUI. Now I am trying to change a specific component, a button, when the application is running. For example, I have 3 buttons in a JPanel. Each button has its onw icon. If I click one of them, it will change its icon, but the other two don't change. I don't know if there is any method for changing a specific component during runtime. If any one knows please let me know, I will appreciate that very much!!!

What you're going to have to do is loop inside the actionlistener but still have accessability to click while its looping. I don't know much about it, but I think you're going to need a thread. Try something like this... (it doesn't work yet, but I have to take off)
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
class buttonxdemo extends JFrame implements ActionListener{
Buttonx mybutton;
//set it all up, make it look pretty =]
public buttonxdemo()
     mybutton = new Buttonx("default");
     getContentPane().add(mybutton.thebutton);
     mybutton.thebutton.addActionListener(this);
     this.setDefaultCloseOperation(3);
     this.setSize(200,200);
public void actionPerformed(ActionEvent ae){
    if (ae.getSource() == mybutton.thebutton)
         if (mybutton.keepGoing)
           mybutton.keepGoing = false;
          else if (!mybutton.keepGoing)
               mybutton.keepGoing = true;
      mybutton = new Buttonx(/*Icon,*/"My Button");
      //getContentPane().remove(mybutton);
      //getContentPane().add(mybutton.thebutton);
      mybutton.startstop();
}//actionperformed
static void main(String args[])
     new buttonxdemo().show();
} //movingicondemo
class Buttonx extends Thread{
public boolean keepGoing;
//public Icon ICx;            //perhaps an array, so you can loop through?
public String strbuttonx;
public JButton thebutton;     //may have to extend JFrame?
public Buttonx(/*Icon IC,*/ String strbutton){
    //ICx = IC;
    strbuttonx = strbutton;
    thebutton = new JButton(strbuttonx);
public void startstop()
    int i = 0;
    while (keepGoing)
      thebutton.setLabel(strbuttonx.substring(0,i));
      //if an array of Icons ICx
      //thebutton.setIcon(ICx);
i++;
if (i > strbuttonx.length() - 1)
i = 0;
try
     Thread.sleep(1000);
catch (InterruptedException ie)
     System.out.println("sleep caught: " + ie);

How to change property file contents during run time?

Hi everyone. First post so go easy on me please.
I have a couple of properties that I want to read from a from a file. To achieve this I simply use:
ResourceBundle.getBundle("my.package.MyItems").getString("MyProperty");
This works like a wonder. The problem is, i want to change the property "MyProperty" during runtime. I've found the properties file (MyItems.properties) inside weblogic, but if a change its contents it does not reflect in the application.
I can come up with a couple of justifications:
* I'm not looking in the right folder/changing the wrong file in the server;
* Weblogic caches the properties file, meaning that I have to redeploy the project (defeating the purpose of actually having a properties file).
Can anyone help with this one?
[EDIT] Forgot important info:
* JDeveloper 11.1.1.4
* Weblogic 11.3 (not 100% sure)
* Both JDev and WebLogic running on Windows 7 64 bits
Thank you in advance!

JDeveloper 11.1.1.4, not 3

I tried it all.
Just an explanation of my context.
I have 1 application with 2 projects in it. First project is called "CommonUI_ViewController" and the second one "FO_ViewController".
The properties file I'm trying to change is located inside "CommonUI_ViewController", in package "PropertiesConfig" and the file is called "PhaseListener.properties".
"FO_ViewController" is dependent on "CommonUI_ViewController". When I run "FO_ViewController" the integrated weblogic server log shows this (among other things):
[10:25:55 AM] Wrote Web Application Module to D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\FO_ViewControllerWebApp.war
[10:25:57 AM] Wrote Web Application Module to D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war
Note: both lines above point to folders. "FO_ViewControllerWebApp.war" and "CommonUI_ViewControllerWebApp.war" are NOT war files, but folders that have that name.
I tried changing the properties file in the following locations:
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\FO_ViewControllerWebApp.war\WEB-INF\lib\adflibSPVCommonUI.jar > PropertiesConfig\PhaseListener.properties;
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war\WEB-INF\lib\adflibSPVCommonUI.jar > PropertiesConfig\PhaseListener.properties;
* D:\JDeveloper\dump\system11.1.1.4.37.59.23\o.j2ee\drs\SPV_BPM\CommonUI_ViewControllerWebApp.war\WEB-INF\classes\PropertiesConfig\PhaseListener.properties (no need to open any jar/war to get to this one).
I changed all these files with different values but no change was shown in the application (using the method in the previous post).
I believe that I'm still doing something wrong :/
Thank you for your help so far vinod_t_krishnan!

Is it possible to add/change a ViewContainerUIElement during runtime?

Hi all,
i want to add/change the content of a ViewContainerUIElement (VCUI) during runtime, but it doesn't work as expected (or hoped;). What i got working so far for an already exising VCUI is:
1. Find the IWDViewContainerInfo for the VCUI
2. If no default view usage exists, create an embedded view usage and set is as default.
3. Set the component usage to the IWDComponentUsageInfo requested.
4. Set the view to the IWDViewUsageInfo of the interface view, which should be the content of the VCUI.
This doesn't work, if it's done after the wdDoInit()s of the controller hierarchy has been processed. The component, which is represented by the usage, is deleted and recreated, but the visual representation doesn't get updated (e.g. no changes on the display) if it's done in an action handler for example. Why? If i change the component usage (cloned component usage) nothing happens too.
Even more problems arise, if i try to add a new VCUI. The steps are pretty the same as before, what is done additionally (and prior the steps above) is:
1. Creating a IWDViewContainerInfo from the IWDViewInfo of the "parent" view.
2. Creating a IWDViewContainerAssignmentInfo from the view usage of the "parent" view
3. Setting the created IWDViewContainerInfo as view container in the assignment.
4. Create the VCUI, set the view container name to the name of the created IWDViewContainerInfo and add the VCUI to an arbitrary container in the parent view.
But this doesn't work, i'm getting:
java.lang.NullPointerException
at com.sap.tc.webdynpro.clientimpl.html.uielib.standard.uradapter.ViewContainerUIElementAdapter.getContent(ViewContainerUIElementAdapter.java:98)
What is wrong? What am i missing?
Thanks in advance.
Stefan

Hi,
I had the same problem with
"java.lang.NullPointerException at com.sap.tc.webdynpro.clientimpl.html.uielib.standard.uradapter.ViewContainerUIElementAdapter.getContent(ViewContainerUIElementAdapter.java:98)"
when I included ViewUsages dynamically in an action handler (outside wdDoInit()).
The code below fixed that problem.
This code creates a new OutboundPlug for the embedding view with the embedded view as target and fires the plug.
// Create OutboundPlug
IWDOutboundPlugInfo outboundPlug = embedderViewInfo.createOutboundPlug();
//Create navigation link
rootViewUsage.createNavigationTarget(outboundPlug.getName(), interfaceViewUsage, "Default");
// fire navigation link
wdThis.wdGetAPI().firePlug(outboundPlug, Collections.EMPTY_MAP);

I hope I could help you. Probably you don't need the information anymore, but perhaps anybody else has the same problem.

Changing Changing Database Location During Runtime

I'm using Netbeans 6.0.1. My database location ALWAYS change in place. That's why I'm planning that there would be a "Database Settings..." inside my program. But I don't know how to change the current: user, password, url settings of my program DURING RUNTIME. Here's my persistence.xml:
<?xml version="1.0" encoding="UTF-8"?>
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="LibraryPU" transaction-type="RESOURCE_LOCAL">
 <provider>oracle.toplink.essentials.PersistenceProvider</provider>
 <class>desktopapplication2.Books</class>
 <properties>
 <property name="toplink.jdbc.user" value="root"/>
 <property name="toplink.jdbc.password" value="password"/>
 <property name="toplink.jdbc.url" value="jdbc:mysql://localhost:3306/Library"/>
 <property name="toplink.jdbc.driver" value="com.mysql.jdbc.Driver"/>
 </properties>
</persistence-unit>
</persistence>

To solve the "why the hell would I want that stuff inside a jar file" issue, I googled a bit and found this
style of approach in a Oracle forum. Essentially think of the persistence.xml file as an template
that the program uses.
I use a properties file to set all local DB configuration aspects. Load the properties at application
startup and set then extract the required fields into a Map to create the persistent unit.
All the "examples" I seen always use a static xml which is never what you need in the real
world.
Map properties = new HashMap();
properties.put(TopLinkProperties.JDBC_URL, dbProps.getString("abc.jdbcurl") );
properties.put(TopLinkProperties.JDBC_DRIVER, dbProps.getString("abc.jdbcdriver"));
properties.put(TopLinkProperties.JDBC_USER, dbProps.getString("abc.user"));
properties.put(TopLinkProperties.JDBC_PASSWORD, dbProps.getString("abc.password"));
EntityManagerFactory emf = Persistence.createEntityManagerFactory("abcPU", properties);
entityManager = emf.createEntityManager();
HTH Altimes.

How can i change/create F1 doku text during runtime

Hi everybody,
I have a problem.
During runtime the user should be able to create a documentation. This documentation must be stored in the F1 help of a data type.
It's easy to get the created help text out of the F1 help.
But is there any possibility to set the help text of a data type during runtime without calling and displaying the document maintenance initial screen?
Can anybody help me?
Thanks & Regards

Hi Max,
thank you for your answer. But I think I don't realy understand.
The documentation should be created for a pattern which is created by the user. I just schould be stored in the F1 help of a data type.
So there is no field on the screen for which i can use this event.
Is there a function or something like this i can call to open the document maintenance starting with the "change" screen?
Thanks & Regards,
Christian

To change view property during runtime

Hi,
I have a scenario where we have 2 views embedded in a window.
First View's property is set to True and second View's property is set to false.
We have a button say "show view" in first view and now we want to change the second view's property to True on click of that button i.e we want to change the view proerties to True during runtime.
We are unabelt o achieve this thruogh plugs are first view is in another DC and second view is in other DC.
Is there any other way to through which we can achieve this?
Any help is this regard is highly appreciated.

Richa Sinha

Hi,
I got your requirement,
Yes if you want navigate back to source view, the problem is you cannot add the the Comp2 again in Comp1 as used comp. This will give cyclic dependancy error.
Try like this.
In Comp2, create an additional view like NavigationView (for example).
In NavigationView create two ViewContainerUIElements (ViewContainerUIElement1 & ViewContainerUIElement2).
Embed this NavigationView into Comp2Window and remove View1's Inteface view & View2 from this window. Change the NavigationView property to true.
And go the Comp2Window Navigation Modeler, embed View1's Inteface view in ViewContainerUIElement1 & View2 in ViewContainerUIElement2.
Now create two context attributes View1Visibility & View2Visibilty in NavigationView and modify the type property to WDVisibility.
Bind these two attributes to corresponding ViewContainerUI elements.
Now in Navigation view, You can create one button and in that button action you can control the visibility of these views.
Hope this info helps. If you need more clarification or info please let me know.

Charan

Changes to Integration Process not reflected at runtime.

I have changed an Integration Process (eg removed a loop) and then activated this in IR and ensured that RunTime Cache is refreshed - I even forced another Run Time Cache refresh via SXI_CACHE.
however the Process is still running under the old version (I can see this from SXMB_MONI_BPE and drilling down into the workflow graphic).
How do I get XI to run the next time with the new version of my process ?

I think you will get an answer sooner when you post in the XI forum which you can find[here.|Process Integration (PI) & SOA Middleware;

What Message type and Process Code to use for Purchase Order Change in 4.6C

I like to implement in SAP R/3 4.6C a scenario for Purchase Order Change, via inbound IDoc.
I have been searching, but could not find what Message Type, Idoc Basic Type and Process Code to use.
I can not imagine this functionality does not exist in 4.6C.
Any suggestions for my problem are welcome.

Hello,
In this case you should use the message PORDCH and BAPI method BAPI_PO_CHANGE but only exist as of release 4.7.
Function module    BAPI_IDOC_INPUT1
Idoc Type              PORDCH01
Message Type      PORDCH
So check carefully the following OSS notes:
[Notes 589066 - BAPI_PO_CHANGE: Incorrect account assignment to network |https://service.sap.com/sap/support/notes/589066] (not be fooled by the description)
[ Notes 197958 - BAPIs for purchase orders - Missing Functions|https://service.sap.com/sap/support/notes/197958]

Change Form Size during runtime

Could someone tell me how to change the size of my VI form during runtime?
I want the ability to click a button and have the height increase by 50 points or so, then go back to the original value after I click the button again.
Thanks for the help!
Angus Cattle from Pool Ranch and Steel Repairs via Joe's Welding.

Ok, that got me on the right track.
For some reason, though, my VI still does not change whenever I click the button.
I have attached my VI, saved in 8.2 format.
Does anyone see why my form doesn't grow by "98" whenever I click the "More >>" button?

Change values in File physical schema during runtime?

Is there any way to change the Directory in physical schema
during runtime?
This is needed so that we can dynamically get the files from
different locations.
Any help is highly appreciated.

Hi,
Yes there is:
Create your physical schema to a parent directory and, at Physical Resourse (File Datastore) use a variable before the name of the file.
Compose the variable with the "child" directory. I like to create the path on execution time.
Does it help you?
