Dynamic change of ring elements

I am wondering if there is a method exist to update ring elements dynamicaly during the vi is running...???
Example: I have a TCP listen VI that get IP address from
different TCP client as they are connecting to the server and I want
the user could select one of these client vs the IP address in the ring
control to execute any test with it...
Thanks in advance for advices

Hello HaemoPhil,
use the property node "strings and values" to change the appereance of your ring at runtime!

Alignment of dynamically changing StaticText element

Having a little trouble centering a dynamically changing StaticText element whose parent container has its alignChildren property set to 'center'. As the text of the element changes, new strings that are assigned to it are truncated to the length of the string the element initially held. If I initially place a string of blank characters that is longer in length than any anticiapted text string the element will ever hold, when the text is updated it is offeset to the left by the number of characters of the initial string that are in excess of the length of the string newly assigned to it. Any ideas or suggestions would be very much appreciated.

Set the initial size of the StaticText with the "characters" property, which will reserve width so it is the proper width.
Also set "justify" to "center" so that it will always be centered within that space.
Note that "characters" is an initial creation property only, and cannot be set after the object has been created.

Dynamically change the db and server in execute sql task

Pkg 2: Moves data from B_STG (Staging DB) to B_Det_STG (Staging DB) ---- option1
Pkg 3: Moves data from B_STG (Staging DB) to B_Det (PC DB) ---- option2
This part is duplicating in both the packages
So they want me to merge both of them into in execute sql task and dynamically change between option1 and option2 depending on a pkg level variable.
So, I create a pkg level variable called ExecutionVariable: 'ANALYSIS' or 'LOADING'
If 'ANALYSIS' it needs to do option1 else option2.
So, I ma trying to create a dynamic connection string in execute sql task.
I change the connection property in execute sql task editor dynamically my giving the expression: @[User::ExecutionVariable] == "ANALYSIS"? @[User::STAGINGDBConnectionString] : @[User::PCDBConnectionString]
which evaluates to : Data Source=AW-ETL-D1;Initial Catalog=Staging;Integrated Security=SSPI;Provider=sqloledb
But when I run the sql task, its giving me an error:
ERROR:
TITLE: Microsoft Visual Studio
Nonfatal errors occurred while saving the package:
Error at PC_DataLoad: The connection "Data Source=AW-ETL-D1;Initial Catalog=Staging;Integrated Security=SSPI;Provider=sqloledb" is not found. This error is thrown by Connections collection when the specific connection element is not found.
Error at PC_DataLoad: The connection "Data Source=AW-ETL-D1;Initial Catalog=Staging;Integrated Security=SSPI;Provider=sqloledb" is not found. This error is thrown by Connections collection when the specific connection element is not found.
Can u please help me.

Hi ,
Don't try to make the "Execute Sql" task as dynamic.
Try to make OLEDB connection Manager as "Dynamic".
Steps:
1. Create OLE DB Connection pointing to any database then set expression to connection string variables like below.
Provider=SQLNCLI10.1;Integrated Security=SSPI;Initial Catalog=YourDBname;Data Source=YourServerName.
2. Make Delayed Validation property to "True".
3. Set the created dynamic OLE DB connection to your Execute SQL task.
4. Change the connection string variable accordingly before running the "Execute SQL" task.
Hope it will help you.

Dynamically add Children Link Element

Hi,
I'm trying to dynamically add a children element, a link, but the action binding refuses to work ...
I've created a custom jsf component, that does nothing at all.
For example, one would use it like:
<my:nothing></my:nothing>So my UI class would have the following methods:
public void encodeBegin(FacesContext context) throws IOException {
public void encodeEnd(FacesContext context) throws IOException {
}The tld file is created, the tag class is working. All the component is working properly.
Now I want to add a link as a child component, but I wat to do it programatically, so I changed the encodeBegin method of my custom ui class:
import javax.faces.el.ValueBinding;
import com.sun.faces.util.Util;
import javax.faces.el.MethodBinding;
import javax.faces.component.UICommand;
import javax.faces.component.html.HtmlCommandLink;
import com.sun.faces.taglib.html_basic.CommandLinkTag;
public void encodeBegin(FacesContext context) throws IOException {
          String myLinkId = "idMyLink";
          String myLinkValue = "myLink:Value";
          String myLinkStyle = "color:green;";
          String myLinkAction = "backup";
          HtmlCommandLink myLink = new HtmlCommandLink();
          myLink.setParent(this);
          myLink.setId( myLinkId );
          if (CommandLinkTag.isValueReference( myLinkValue )) {
               ValueBinding vb = Util.getValueBinding( myLinkValue );
               myLink.setValueBinding("value", vb);
          } else {
               myLink.setValue( myLinkValue );
          if (CommandLinkTag.isValueReference( myLinkStyle )) {
               ValueBinding vb = Util.getValueBinding( myLinkStyle );
               myLink.setValueBinding("style", vb);
          } else {
               myLink.setStyle( myLinkStyle );
          if(myLinkAction!=null) {
               if (CommandLinkTag.isValueReference( myLinkAction )) {
                    System.err.println("Id="+myLinkId+":TRUE:getAccao:isValueReference:"+myLinkAction);
                    MethodBinding vb = getFacesContext().getApplication().createMethodBinding(myLinkAction, null);
                    myLink.setAction(vb);
               } else {
                    System.err.println("Id="+myLinkId+":FALSE:getAccao:isValueReference:"+myLinkAction);
                    final String outcome = cNfo.getAccao();
                    MethodBinding vb = Util.createConstantMethodBinding( myLinkAction );
                    myLink.setAction(vb);
          myLink.encodeBegin(getFacesContext());
          myLink.encodeEnd(getFacesContext());
}This seems to work, but not quite ... the link appears as expected, the value references for value and style are correctly passed, but the action doesn't work at all.
For example if I change to:
String myLinkValue = "#{mybean.linkText}";And I have the following method created on my managed bean:
     public String getLinkText() {
          return "This is myLink Text!";
     }Is successfully calls and retrieves the value from the method. Same happens to the style property.
Now for the action, if I change to:
String myLinkAction = "#{mybean.doMyLinkAction}";And I have the following method created on my managed bean:
     public String doMyLinkAction() {
          return "backup";
     }The result is nothing ... I mean the method is not called at all. The "backup" is properly defined on my "faces-config.xml":
   <navigation-rule>
      <from-view-id>/testPage.jsp</from-view-id>
      <navigation-case>
         <from-outcome>yes</from-outcome>
         <to-view-id>/yes.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>no</from-outcome>
         <to-view-id>/no.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>backup</from-outcome>
         <to-view-id>/backup.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>If I create the link manually on the web page:
<h:commandLink id="myLinkManual" value="Manually Created Link" style="" action="#{mybean.doMyLinkAction}"/>It does work (the backup.jsp page is shown), so the methods are properly configured, only the action binding does not work.
Wether I use a string "backup" or a reference "#{mybean.doMyLinkAction}" I cannot make it work.
On the console I get the following results, for each value I test (string "backup" or reference "#{mybean.doMyLinkAction}"):
Id=idMyLink:TRUE:getAccao:isValueReference:backup
Id=idMyLink:FALSE:getAccao:isValueReference:#{mybean.doMyLinkAction}So the "if (CommandLinkTag.isValueReference( myLinkAction )) {" is working properly ... that just leaves me with the action method binding instructions ...
Why don't they work?
Any Help Appreciated ... Thanks in Advance!

c'mon guys ... can anyone test this and help me out?
Pleeeeeease ... I'm really needing this working out.
Thanks

Dynamically Change UIBBs in GAF. Is it possible ?

Hello,
I have a query in FPM to which I would like to draw your attention to.
Can I dynamically change my UIBBs within a single mainstep in FPM GAF ? if so, which method can help me do this ?
I created a single Web dynpro Component with 5 component configurations.
I am controlling the visibility of several UI elements within this single component through these component configurations.
Each configuration refers to a business scenario.
I configured this single interface view at the UIBB level with the configuration name for a main step.
I was able add multiple uibbs at this level with different configuration names.
Now, I do not know how to toggle between these UIBBs?. I do not want to create multiple variants
because all the other main steps are same for all the business scenarios.
Thanks for your time.
Regards,
Kiran

Hello Kiran,
This is achieveable. You need to implement the IF_FPM_GAF_CONF_EXIT WD interface in your AppCC. This interface provides a method OVERRIDE_EVENT in the component controller of your AppCC. This method has an importing parameter IO_GAF which has various methods to help you change the configuration of the application at runtime and also the UIBB's on a particular mainstep.

Merging of 2 Cells in WD ABAP ALV Header & Dynamically change the header

Hello Experts,
I have two main requirements with respect to WD ABAP - ALV report creation
1) Two feilds in the header of ALV GRID created in the WD ABAP screen must be merged as shown below(Month Column) ,
| January | February |
| Col 1 | Col2 | Col 1 | Col2 |
2) The header value(Month) should dynamically change based on the current date.
For Eg: If June 2011 is the current month , the ALV table should start from June 2011 and displayed till May 2012.
Looking forward for your valuable inputs @ the earliest

Dynamically changing the prompt on ksh

Hi ,
I couldn't find a better forum to post this query, that's why I put it under Installation.
How do you make sure that the ksh prompt displays the current directory as well? I tried various combinations...even the examples say that PS1="[! $PWD]" should work, but that doesn't seem to work on ksh. Can anything be done to ensure that the prompt changes whenever I change the working directory?
Thanks in advance,
Amrith.

Hi,
I have no idea about changing the text element dynamically.
But you can refresh the screen by the following sample coding.
You can accomplish this with a RFC enabled Function module.
1. Create a function module. The only functionality will be to wait for 10 secs.
2. Create a subroutine which will set a user-command.
3. and at user-command call the function module.
Below is the code, I found on the web. It is quite simple..
DATA: ZNUM LIKE SY-TABIX.
: GET TIME.
: WRITE: /01 'Update Number:', ZNUM, SY-UZEIT.
: CALL FUNCTION 'Z_WAIT_30_SECS'
: STARTING NEW TASK 'IF'
: PERFORMING START_REFRESH ON END OF TASK.
: AT USER-COMMAND.
: IF SY-UCOMM = 'REFR'.
: SY-LSIND = SY-LSIND - 1.
: ADD 1 TO ZNUM.
: GET TIME.
: WRITE: /01 'Update Number:', ZNUM, SY-UZEIT.
: CALL FUNCTION 'Z_WAIT_30_SECS'
: STARTING NEW TASK 'IF'
: PERFORMING START_REFRESH ON END OF TASK.
: ENDIF.
: */ Program Subroutines
: FORM START_REFRESH USING TASKNAME.
: SET USER-COMMAND 'REFR'.
: ENDFORM. "
: FUNCTION Z_WAIT_30_SECS.
: ""Local interface:
: DATA: ZTIME LIKE SY-UZEIT.
: GET TIME.
: ZTIME = SY-UZEIT + 30.
: DO.
: GET TIME.
: IF SY-UZEIT >= ZTIME.
: EXIT.
: ENDIF.
: ENDDO.
: ENDFUNCTION.
Hope this helps.

Custom cursor - dynamically change colour

Since I failed to gain access to [Embed]ed SWF file to change
its properies from within Flex :-(
has anyone got any ideas how to create a custom cursor and
dynamically change its colour.
Let's say we have a brush or a pencil cursor and we want to
change the colour of its tip, when a certain coloured button is
pressed with it.
Thank you.

Use sym for your element.
sym.$("button").css({'cursor':'pointer'});

Dynamically changing the UI

Hi Everybody,
I have a view (view 1) which is being mapped with another view(view2). When I trigger my firePlug from View 1, the UI element should be a InputField with STRING as Datatype. and Similarly when I load the View2 thru wdinit(), it should dynamically change into InputField with Date...
Regards/Guru

Hi Kumara,
it is not possible to change the Input field type. But if create a second field in the component controller with the type date and than copy the string with the method new date (year, mm, dd) to the this new field.
You must transfrom the String in 3 int field. (2007-03-20)
year = 2007; mm = 03 ; dd = 20 )
Map this date field to the view2 an you get in this view the Date
Component Controller
Field 1 --> type String
Field 2--> type date
View 1 --> Controller
Field1 is mapped to the controller Field 1
View 2 --> controller
Field 2 is mapped to the controller field 2
I hope this helps

Dynamically change text field type

I have a form which displays a decimal field. However when certain conditions are met, I need to change its type to Text, so the user can enter any alphanumeric character.
How do I achieve that with Javascript code? Is it even possible?

Actually, you can dynamically change a textfield.type. AS2.0
You need two elements.
txt.type = "input";
txt.selectable = true;
However, if you have the textfield in a btn you will need to
delete the onRelease function before you can make the tf function correctly.
btn.onRelease = function()
delete this.onRelease;
this.txt.type = "input";
this.txt.selectable = true;

Using DelayQueue with dynamically changing delay times?

Greetings all:
First-time poster, so please be gentle. :-)
I am implementing a cache timer task whose job is to removes idle elements from a cache after x time, and was considering a DelayQueue as potentially more efficient than iterating through the entire cache each time. Important point is that the delay time of elements in the queue will be dynamically changing while they're in the queue, until the point when they become idle, i.e., each time an element's content changes, its expiration time moves further out.
I went looking in the DelayQueue source (and from there to PriorityQueue) as I was interested to see how it implements its sorting mechanism, and it appears to me that it may not handle this properly. Specifically, it appears that the queue is sorted when elements are added or removed but not otherwise, so that you could end up with the head of the queue being an element that has not really expired.
Question: Has anyone used a DelayQueue for this kind of scenario, and if so, did it work as expected?
Thanks,
Brian

If you want this behaviour I suggest you look at
overriding LinkedHashMap as it has a means to
maintain sorted from most recently accessed to last
accessed.
Thus to clear it all you need to do is remove the
oldest elements.Interesting. Currently I'm using a HashMap so changing to a LinkedHashMap would require virtually no changes to existing code. It still won't quite work as-is, though, because access only gets updated on put's and remove's, whereas I would need access updated on any modification to a contained object as well. I'll think about it a bit more - thanks for the suggestion.

Best Practice: Dynamically changing Item-Level permissions?

Hi all,
Can you share your opinion on the best practice for Dynamically changing item permissions?
For example, given this scenario:
Item Creator can create an initial item.
After item creator creates, the item becomes read-only for him. Other users can create, but they can only see their own entries (Created by).
At any point in time, other users can be given Read access (or any other access) by an Administrator to a specific item.
The item is then given edit permission to a Reviewer and Approver. Reviewers can only edit, and Approvers can only approve.
After the item has been reviewed, the item becomes read-only to everyone.
I read that there is only a specific number of unique permissions for a List / Library before performance issues start to set in. Given the requirements above, it looks like item-level permission is unavoidable.
Do you have certain ideas how best to go with this?
Thank you!

Hi,
According to your post, my understanding is that you wanted to change item level permission.
There is no out of the box way to accomplish this with SharePoint.
You can create a custom permission level using Visual Studio to allow users to add & view items, but not edit permission.
Then create a group with the custom permission level. The users in this group would have the permission of create & add permission, but they could no edit the item.
In the CodePlex, there is a custom workflow activities, but by default it only have four permission level:
Full Control , Design ,Contribute and Read.
You should also customize some permission levels for your scenario.
What’s more, when use the SharePoint 2013 designer, you should only use the 2010 platform to create the workflow using this activities,

How to change the screen element of a single field in a table control

Hi Gurus,
I want to change the screen element of a single field (or the whole row) in a table control according to a condition.
I have 2 columns in the table control. One is an input column and one output only. When user enters values into the input column, they need to be compared against the values in the other column, and if there is a discrepancy, the row where the discrepancy is needs to be highlighted.
I have tried the following code which highlights the whole column ...
CONTROLS: TC_ZVOYG_BINS TYPE TABLEVIEW USING SCREEN 0500.
DATA: wa_tc_zvoyg_col LIKE LINE OF TC_ZVOYG_BINS-cols.
LOOP AT G_TC_ZVOYG_BINS_ITAB
           INTO G_TC_ZVOYG_BINS_WA.
    if G_TC_ZVOYG_BINS_WA-zdelivery_bin ne G_TC_ZVOYG_BINS_WA-zactual_bin.
      loop at screen.
        IF screen-name = 'ZVOYG_BINS-ZACTUAL_BIN'.
          wa_tc_zvoyg_col-screen-intensified = 1.
          MODIFY tc_zvoyg_bins-cols FROM wa_tc_zvoyg_col TRANSPORTING
          screen-intensified WHERE screen-name = screen-name.
        endif.
      endloop.
    endif.
endloop.
And also the following code which makes no change ...
LOOP AT G_TC_ZVOYG_BINS_ITAB
           INTO G_TC_ZVOYG_BINS_WA.
    if G_TC_ZVOYG_BINS_WA-zdelivery_bin ne G_TC_ZVOYG_BINS_WA-zactual_bin.
      loop at screen.
        IF screen-name = 'ZVOYG_BINS-ZACTUAL_BIN'.
          screen-intensified = '1'.
          modify screen.
        endif.
      endloop.
    endif.
endloop.
Thanks in advance.

Hi,
The modification of a screen element attribute (LOOP AT SCREEN...MODIFY SCREEN) must always be done in the PBO (for a dynpro, it will be in a PBO module, i.e. declared by MODULE ... OUTPUT)
About the loop at the internal table, it is done automatically by the system, also during the PBO, you'll find something like LOOP [AT itab] ... WITH CONTROL ... in the PBO part of the screen flow logic (note: you may have to complete with a supplementary READ TABLE if you don't use AT itab). So you don't need an additional loop.
Best regards
Sandra

How to dynamically change the text of a TextObject with embedded DataField?

Hi
I'm trying to dynamically change the text of a TextObject at runtime, by using the .NET library. My problem is that if one or more DatabaseFieldDefinition is embedded inside my text, I'm unable to change the "static text" only, by keeping the field, e.g. I have :
Text1 => "Contact Name: {Contact.Name}"
and I'd like to change it to anything else like:
Text1 => "Nom du Contact: {Contact.Name}"
Half of my TextObject is static text while second part comes from the dataset.
(of course the translation is dynamic - it is called at run-time and the new value to be set depends on the calling application language)
If I simply modify the Text property of my TextObject, the {Contact.Name} embedded field is not evaluated anymore by the Crystal Engine, but considered as a single text.
Using formulas or parameters looks quite difficult, because it means having many ones just for translation needs - I cannot control the way my users will create their reports and "force them" to use complex methods just in order to put a text and a value together...
Anyone knows how to deal with that ?

Only way I can think of doing this:
1) Create a formula (call it lang) and enter the string "Contact Name" in it
2) Place the {Contact.Name} field next to the string
3) So now you have:
ContactName: {Contact.Name}
4) Check what localization you are after. If you need "Nom du Contact", change the lang formula so it shows "Nom du Contact" using the code below:
Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
Public Class Form1
Inherits System.Windows.Forms.Form
Dim Report As New CrystalReport1()
Dim FormulaFields As FormulaFieldDefinitions
Dim FormulaField As FormulaFieldDefinition
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
FormulaFields = Report.DataDefinition.FormulaFields
FormulaField = FormulaFields.Item(0)
FormulaField.Text = "[formula text]"
CrystalReportViewer1.ReportSource = Report
End Sub
I realize this may not give you consistent spacing as the translations may have strings of differnt length. Perhaps someone has other idea(s)...
