How to make Binding

Hi,
How to make binding for newely created methods.From Task -> Method.
For me the Binding icon is not activated.can i know the solution.
Please givfe the solution ASAP.

hi,
PFTC, use TS as type and type in the task number.
Now click change.
There you'll see description, text and objectmethod.
type in the objecttype and the method and press enter. Now notice the green icon somewhere below the text method. this is the binding button.
This is also accessible via the menu: path goto>binding>object method
Kind regards, Rob Dielemans

How to make a mac managed in wgm

Could anyone point me in the direction of a how to make a mac managed in workgroup manager, ive done it before, but i cant remember how to do it, all i can remember was that once the mac was managed it had a $ after it, then WGM can manage that macs preferences.
Thanks
Rob

Hi John
I think im trying to do something different, to enable WGM to control clients macs preferences, i had to add a computer to workgroup manager in accounts/computer tab, when the computer was correctly bound (or binded) it looks like my picture, with a $ at the end of it, im trying to add new computers to this list, i just cant remember how to do it, like i say i could have done it through open directory utility.

How to make a round Slider with an image ?

hello everybody,
I'm back and i have a new question : how to make a round Slider (like a volume knob) with an image ?
I see this very interisting tutorial : http://fxexperience.com/2012/01/fun-javafx-2-0-audio-player/ but it use a private class from com.sun.javafx.scene.control.skin.SkinBase...
thank you for your answer.
Gaëtan.

I'm guessing you could subclass Slider to create a class SliderKnob.
At some stage in the process, not sure where (perhaps after calling super in the constructor), you could look up the slider region's child thumbnail and track and call setVisible(false) and setManaged(false) on them, create an ImageView for your knob, add the knob ImageView to the slider's region and bind the ImageView's rotateProperty to the slider's valueProperty(). Not sure that that is any better than using the SkinBase stuff, but at least it is an alternative idea.
Everything to create your own controls has not been added to the public API, so if you want to make your own controls in the same way the JavaFX does them (i.e. with Skin's and Behaviours and stuff like that) you have to make use of com.sun classes unless you can subclass and modify the workings of existing controls similar to what is proposed in the preceding paragraph.

Hi ashuthosh,
What is the structure of your import and Export parameters of your RFC.
There are 2 ways to acheive it.
In the RFC either
1. Use a Table parameter
2. Use a Export Structure
If you use a Table parameter in your RFC then in your webdynpro when you import your adaptive RFC model you would get the Table as a class.
Assume your RFC/BAPI is called "Bapi_RFC_Insert"
write the code
Bapi_RFC_Insert in = new Bapi_RFC_Insert();
wdContext.nodeBAPI_RFC_Insert_InputElement().bind(in);
<TableName> <someName> = new <TableName>
<someName>.setTabValue1();
<someName>.setTabValue2();
in.add<>(<someName>);
This should pass values as a batch.
You can also do this using Export parameters. But a table is much better.
Let me know if you require more information.
regards
ravi

How to make a column editable

Hi all,
I want a column to have checkboxes in my table where user can select at runtime.
I added one colum to my table with Checkboxes.But the checkboxes are comming in non Editable mode.
How to make them editable???
My context structure is already binded to my table..now i added one ValueNode with One attribute and i binded that texts property of checkbox to the Valueattribute
The cardinality of my ValueNode is 1..1 and selection is 0..1
Regards
Chandrashekar.

Hi,
when you added the checkbox as cell editor, then go to it's property:
set "enable" as true.
set "readonly" as false.
and create a boolean attribute "checked" in the table bode and bind it to the check box value property.
And in the onAction of checkbox wirte the code to select or deselect the checkbox.
and set the value as follows:
wdcontext.nodeTable().getcurrentElement().setAttribuiteValue("checked", true);

How to make a SELECT LIST READONLY

Hi,
I have a form to update the existing values in a table. Primary column is based on a Select List.
So when user goto update screen they SHOULD NOT BE ABLE TO CHANGE the primary filed(means the value display in the Select List).
SO to make this one I have make that select list read only. But not like other items even when we make select list read only it still allow user to change the value. So basically read only property not working for select text.
There are many post in this regading same issue. Some of them recomended to make it disabled. But when we make a item disabled then when user POST that form, Apex not POST any disabled item values. Basically disabled items values not passing next form. So making item dissable also not a solution.
I have read almost 20 post in here regarrding this and didnt get any solution for this. So please let me know if anyone knows how to make a select list read only (which is working same as read only text boxes, means that value pass when user POST the form).
Thanks in advance...

You define a function(this is based aorund jQuery selectors) in the page header like
<script>
var makereadonly = function(selector, makeReadonly) {
      $(selector).filter("select").each(function(i){
          var select = $(this);
          //remove any existing readonly handler
          if(this.readonlyFn) select.unbind("change", this.readonlyFn);
          if(this.readonlyIndex) this.readonlyIndex = null;
          if(makeReadonly) {
              this.readonlyIndex = this.selectedIndex;
              $(this).css('background-color','#CDCDCD'); //Adds a background colour to readonly item
              this.readonlyFn = function(){
                  this.selectedIndex = this.readonlyIndex;
              select.bind("change", this.readonlyFn);
      //For input items
      $(selector).filter("input,textarea").attr('readOnly','readOnly');
      $(selector).filter("input,textarea").css('background-color','#CDCDCD');
</script>and apply it using a jQuery selector (call it in the "execute on page load" or any other JS code)
makereadonly('#ITEMNAME1,#ITEMNAME2,#ITEMNAME3',true);Not that all of these methods(that act at the client side) will only prevent the user from modifying it 'normally', they could manipulate these readonly items using Javascript(or using firebug or any tool like that). So its better to make sure that your don't use the item value(from the page) for processing.

Hi,
I have a requirement like , have to create the checkbox list dynamically.
I am doing it through the binding. But i want to make the HtmlSelectManyCheckBox should be scrollable.
I am doing as belwo
HtmlPanelGrid innerGrid = new HtmlPanelGrid();
               innerGrid.setWidth("150%");
               innerGrid.setStyle("height:150px; border:2px; overflow-x: scroll; overflow-y: scroll;");
HtmlSelectManyCheckbox selectBox = new HtmlSelectManyCheckbox();
               selectBox.setBorder(3);
               selectBox.setLayout("pageDirection");
               selectBox.setStyleClass("selectManyCheckbox");
               selectBox.setTitle(catVO.getCatName());
               // adding the selectitems to select many list box
               UISelectItems items = new UISelectItems();
               items.setValue(catVO.getInterestItems());
               selectBox.getChildren().add(items);
innerGrid.getChildren.add(selectBox);Though i set the style of the grid to be scrollable , but its not working properly.
Plz help me , how to make it scrollable.

Thank u , ok how to apply the styles or style class to the HtmlPanelGroup.Uh, just the same way.
And i have to create the lists dynamically , and i dont have the count of the number of panelGroups.You already have the count of checkboxes.
How can i put them in table.The same way.

How to make a call to service from site studio templates?

Hi,
May be this is very basic but I am not able to figure out how to make a call to a service from site studio templates (hcsp). I have seen one example of service call in the dynamic list fragment. It makes a call to SS_GET_SEARCH_RESULTS service using executeService() method. But it doesn't take any parameters and also not very how returned results are captured.
I want to execute WCM_PLACEHOLDER service. It takes 2 main parameters dataFileDocName and templateDocName. The returned result is typically a html response.
The service typically is executed using http request and the url would be something like this
http://hd-pratapm/ucm/idcplg?IdcService=WCM_PLACEHOLDER&dataFileDocName=VIRTUSAINC&templateDocName=DETAILS_REGION_TEMPLATE
I think SS_GET_SEARCH_RESULTS service works in the similar fashion. I want to execute WCM_PLACEHOLDER service too using executeService() method. How to work with this? How can we pass parameters and capture returned results?
Regards,
Pratap

Hey Pratap,
If you are on a standard Site Studio template (page or subtemplate) you should be able to call the wcmPlaceholder idoc function directly. In fact calling the idoc function provides a lot more functionality then the service call (they locked down a few things in the service call since it is designed to be called from an external application).
The idoc call would look something like:  (taken from page 208 in this doc: http://download.oracle.com/docs/cd/E10316_01/SiteStudio/10gr4/Pdf/Site_Studio_10gR4_Designer_Guide.pdf)
As a general note when you are in idoc script and want to execute a service you call <$executeService()$> as you saw in the dynamic list. The parameters that the service runs on are in the data binder of the current request. To set parameters for an execute service you simply set idoc variables on the page before it. Example:


As for the response when you execute an idoc function, like wcmPlaceholder, that returns a String the response is immediately output to the page in the location you called the function. This would be similar in concept to a jsp scriptlet that outputs a string <%=myResponseString%>

How to make group visble and hidden

I have to make one group(which consists of some field) visible and hidden on tableselect. Initially that group should not visible and after selecting table those group need to show. How to make it during runtime..Right now i made the table leadselect -1 so it is not selected. So how to make it hidden.
Thnaks
Nitya

Use a calculated attribute (read-only, type=Visibility) and implement the get-method like
WDVisibility getGroupVisibility(...)
return wdContext.node<TableDataSource>.getLeadSelection() == IWDNode.NO_SELECTION
? WDVisibility.NONE : WDVisibilty.VISIBLE;
Bind the "visible" property of the group to this attribute.

How to make VideoRecorderBrush scollable?

Hi. My root layout is a Grid and I'm using a Rectangle to display the AudioVideoCaptureDevice's viewfinder. I have a option to set the capture resolution to any resolution that is available by the API. When the capture resolution is
greater that the rectangle a lot of the information of the recording (video picture) is unseen. I know I can later see it by playing it back with a fill stretch. Can you teach me how to see it while recording i.a.w make some control scrollable like
the video recorder brush? Thanks in advance:-)

I followed the "how to capture videos in Windows Phone" tutorial and it used VideoCaptureDevice API from Microsoft.Devices namespace. I edited the code and where able to capture videos using AudioVideoCaptureDevice (It took me a long time to get
it right). Here is the relevant code:
XAML:

<Grid x:Name="LayoutRoot"
Background="Transparent">

<Rectangle x:Name="viewfinderRectangle" Width="auto" Height="auto" Stroke="White" Tap="ToggleZoom_Tap" StrokeThickness="5" HorizontalAlignment="Center" VerticalAlignment="Center">
<Rectangle.Fill>
<LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0">
<GradientStop Color="Black" Offset="0"/>
<GradientStop Color="White" Offset="1"/>
</LinearGradientBrush>
</Rectangle.Fill>
</Rectangle>
<MediaElement x:Name="VideoPlayer" AutoPlay="True" Width="800" Height="480" RenderTransformOrigin="0.72,0.479" VerticalAlignment="Center" HorizontalAlignment="Center" Stretch="None"/>

I added some other methods that are related to the Video Capturing but you can just look in InitializeVideoRecorder to see how I'm binding the AudioVideoCaptureDevice preview to the rectangle...Tell me if you need more info and thanks so long

WPF: How to make Tab Header to show three different icons?

Our WPF application needs Tab header to show three different icons and Foreground.
If tab is not selected, show one icon and black foreground. If tab is selected, show another icon and white foreground. If tab is selected and also require show Chromestyle, show third icon and red foreground.
we have tried the following code. However, MultiDataTrigger section does not work.
<TabItem x:Name="tabItemSetup" Header="Setup">
<TabItem.HeaderTemplate>
<DataTemplate>
<StackPanel Orientation="Vertical">
<Image x:Name="imgSetup" Height="50" Width="65" Source="Resources/Images/UNSELECTED_Setup Icon.png" DockPanel.Dock="Top" />
<TextBlock x:Name="txtSetup" Text="{Binding}" Foreground="Black" Style="{StaticResource TabTextStyle}" DockPanel.Dock="Bottom" FontFamily="Eras ITC" FontSize="13.333"/>
</StackPanel>
<DataTemplate.Triggers>
<DataTrigger Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType={x:Type TabItem}}}" Value="True">
<Setter TargetName="txtSetup" Property="Foreground" Value="White"/>
<Setter TargetName="imgSetup" Property="Source" Value="Resources/Images/SELECTED_Setup Icon.png"/>
</DataTrigger>
<MultiDataTrigger>
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding IsChromeStyle}" Value="True"/>
<Condition Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType={x:Type TabItem}}}" Value="True"/>
</MultiDataTrigger.Conditions>
<MultiDataTrigger.Setters>
<Setter TargetName="txtSetup" Property="Foreground" Value="Red"/>
<Setter TargetName="imgSetup" Property="Source" Value="Resources/Images/Chrome SELECTED_Setup Icon.png"/>
</MultiDataTrigger.Setters>
</MultiDataTrigger>
</DataTemplate.Triggers>
</DataTemplate>
</TabItem.HeaderTemplate>
</TabItem>
Does anyone know how to make it work? Thx!

Where is the IsChromeStyle property defined? It is the Header, i.e. the string "Setup" that is the DataContext of the HeaderTemplate and the a string has no property called IsChromeStyle so you must specify a source for the binding.
If for example the DataContext object of the TabControl, or the parent of the TabControl (for example the window or whatever) has a property called IsChromeStyle you could bind to this one using a RelativeSource:
<MultiDataTrigger.Conditions>
<Condition Binding="{Binding DataContext.IsChromeStyle, RelativeSource={RelativeSource AncestorType={x:Type TabControl}}}" Value="True"/>
<Condition Binding="{Binding IsSelected, RelativeSource={RelativeSource AncestorType={x:Type TabItem}}}" Value="True"/>
</MultiDataTrigger.Conditions>
Then it should work. It is the binding that fails.

How to make a global variabel

I have a problem
I wanna make global variable (not bind variable), and every page in portal can use this variable.
Can anybody tell me how to make this var ?
TIA

I have used session variables to do what you are trying to do.
Checkout http://technet.oracle.com/products/iportal/files/pdkjan/articles/primer.session.storage.html for a primer on session storage, and especially http://technet.oracle.com/products/iportal/files/pdkjan/plsql/doc/sdk20pkg.htm for how to use wwsto_api_session.
