How to create transparent image at run-time?

How to create transparent image at run-time? I mean I want to create a (new) transparent image1, then show other (loaded) transparent image2 to image1, then show image1 to a DC. The problem is - image1 has non-transparent background...

i'm not sure, but you can set the alpha value to 0 in all pixels which are 'in' the background..

How to create widget Dynamically at run time using action script

i have created widget's in my application . but in the main page i want only selected widgets to be displayed..
lets say i have 3 categories of users for which i've created 3 widget groups i.e. search , update , report. with in these groups i have number of widgets. if user belongs to searchUser category only search widget group has to be displayed in my main page, if user belongs to updateUser group i want to display search and update widget group in my main page and so on..
thanx

Assuming these widgets are always on your main page, you could bind the visible parameter of the widget to variable, and then set that variable depending on the users group. So you could mark your groups search =1, update =2, report =3. Have a Bindable variable that you can set corrisponding to the group of the current user
[Bindable]private var groupLevel:int;
then in your search widget tag, set the visible parameter like so visible={(groupLevel>=1)?true:false}
user widget would be visible={(groupLevel>=2)?true:false}
and report widget visible={(groupLevel==3)?true:false}
that should allow the widget so appear for the appropriate group.

How to create a datablock at run time?

I want to create a datablock with database item at runtime.
Is it possible?
plz help.

actually i have to show my records in multiple blocks. I arranged it in 6 blocks in a form, but user says
it is possible we need more blocks to show now form is getting heavy. so i want new blocks will be created
as and when required.You cannot create blocks on the fly. You should strongly push for new forms rather than keep adding functionality to the same form. Design at that level should be your call not the user.

Create the pages at run time in smartforms

How to create the pages at run time in smartforms????

Hi..
You cannot create pages at run time, however you can decide based upon conditions and using commands in Smartforms, which page needs to be displayed next.
Those pages should be created beforehand.

Create LinkToAction with Image by run time

Hi,
I want to create linkToAction UI's with different images by run time. But if I try the code below I get always the same image for every linkToAction UI. What is my mistake? And how can I solve this problem?
 for (int i = 0; i < wdContext.nodeGlob_Struc().size(); i++){
 IWDLinkToAction linkToAction = (IWDLinkToAction)
 view.createElement(IWDLinkToAction.class, "linkToAction"+i);
 IPrivateDocPreAppView.ILinkToActionElement nodeLink =
 wdContext.createLinkToActionElement();
 wdContext.nodeLinkToAction().bind(nodeLink);
 wdContext.currentLinkToActionElement().setImageSource(
 wdContext.nodeGlob_Struc().getGlob_StrucElementAt(i).
 getUrl_Thumbnail() );
 linkToAction.bindImageSource( wdContext.nodeGlob_Struc().
 getNodeInfo().getAttribute(IGlob_StrucElement.URL__THUMBNAIL) );
 theGroupBox.addChild(linkToAction);
regards,
Sharam

Hallo Sharam,
The Web Dynro binding model does not support "index binding". This means binding multiple image UI elments to the same attribute in a multiple context node (cardinaltiy 1..n) means, that all images are bound to the node's lead selection. That's what you implement with
linkToAction.bindImageSource( wdContext.nodeGlob_Struc(). getNodeInfo().getAttribute(IGlob_StrucElement.URL__THUMBNAIL) );
Armin's solution is based on the fact, that he breaks the data binding principle by directly setting the imageSource property values.
Sharam, when reviewing your code I find several "problems":
1. Never ever store UI elements in the context. I assume you do this in order to access UI elements outside wdDoModifyView() as it is static. There is no need to do this.
2. Then you break databinding by setting the imageSource property in the linkToAction object (stored in the context) directly, breaking databinding.
3.) Finally you "un-do" this hard property setting by binding it to the context again. This has the effect you described.
Breaking the data binding principle for UI elements has an important drawback. It also breaks the generic Web Dynpro caching mechanisms. Read my article on
<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/301d715e-0b01-0010-1a8b-f1f83d175972">Best Practices for Building Client-Independent Web Dynpro UIs</a>, section Coding Rules, rule Implement Fine-Grain UI Manipulations on Context but Not on UI Element Level:
To maximize the rendering performance of your Web Dynpro application, implement all fine-grain UI manipulations on context instead of UI element level. This means do not call the setter-methods of UI element objects inside wdDoModifyView()directly but bind the related properties to the context and call the corresponding setter methods outside wdDoModifyView():
Not: wdDoModifyView(){ theField.setEnabled(true) }
But: wdDoInit(){ wdContext.currentFieldNode.setEnabled(true) }.
Otherwise Web Dynpros caching mechanisms cannot speed up the rendering of view layouts.
The view controllers wdDoModifyView() method is designed for a special purpose: the creation of a UI tree or UI sub-tree at runtime in case it is not possible to declare the UI at design time. The method is neither intended for fine-grain UI manipulations nor for context manipulations. Fine-grain UI manipulations are achieved via means of data binding. Context manipulations are done in wdDoInit(), action event handlers or event handlers.
Unfortunately, the name wdDoModifyView() is somewhat misleading since the purpose of it is to create (and not to modify) a UI tree dynamically. While the usage of wdDoModifyView() in order to create a UI tree initially (firstTime == true) is not performance critical, modifying an existing UI tree (firstTime == false) is: Changing only one single attribute of a single UI element within wdDoModifyView() flags the complete view containing the control as dirty and the complete view must be completely re-rendered again depending on the size and complexity of the view this can result in significant performance hits.
But in your case databinding cannot be applied, as index binding is not supported. The only databinding solution must use multiple/n nodes of cardinatliy 1..1 instead of 1 node of cardinality 1..n with no node elements. And this would require further coding for dynamic context node creation, copy logic based on value semantic.

How create bath file in run time in java

Hi all
i run one bath file by using process class but i create bath file in run time in java .please help me with code.

Dynamically Writing a batch file in Java is exactly the same as writing to a simple text file.... you just give it the file extension ".bat".
If you can't write to a simple text file yet, you should probably buy a Java book and start working through it.

Can you set an image at run time? Does it really work?

I have read that others have been able to set an image at run time, but I cannot seem to get it to work (the image I set does not load).
What I do is have a page, call it page2, that has two image components on it. In the constructor for page2 I do this:
// Additional user provided initialization code
image1.setValue("bike1.JPG");
image2.setValue("bike2.JPG");
The jpg files are in the build directory:
C:\Documents and Settings\Darrin\My Documents\Creator\Projects\ImageTest\build\images
The odd thing is that for the first image component(image1), I set a default jpg file (nogo.JPG that is in the same directory as the other two), and that does load.
In fact, when I I check the value of image1 in afterRenderResponse by calling image1.getValue() it still has the default image (nogo.JPG) instead of the one I set it to (bike1.JPG) in the constructor by calling image1.setValue("bike1.JPG");
So, either the image1.setValue() has no effect, or something is overwriting it.
What is the trick to getting an image to load at run time like this?
THANKS!

Well after several more hours of banging myh ead against the wall, I still cannot get this to work. 
I read in the constructor comments that whatever is in the jsp file will override the backing bean's constructor, so that might be part of the problem, but others I thought got this to work using a similar method. 
Here is what I tried last which still does not work, but mimics what others have said did work for them: 
//See if the default jpg file can even be copied over
 image3.setHeight(image1.getHeight());
 image3.setUrl(image1.getUrl());
 image3.setValue(image1.getValue());
 
 Integer aiw = new Integer("1");
 float aar = 0;
 float ar = 0;
 
 ImageIcon ii = new ImageIcon("C:/Documents and Settings/Darrin/My Documents/Creator/Projects/ImageTest/build/images/bike1.JPG");
 ar = (float)ii.getIconHeight()/(float)ii.getIconWidth();
 aiw = new Integer(ii.getIconHeight());
 aar = ar*aiw.intValue();
 image1.setHeight(""+(int)aar);
 image1.setUrl("images/bike1.JPG");
 image2.setValue("C:/Documents and Settings/Darrin/My Documents/Creator/Projects/ImageTest/build/images\\bike2.JPG");
 image2.setUrl("C:/Documents and Settings/Darrin/My Documents/Creator/Projects/ImageTest/build/images\\bike2.JPG");
 Note that when I run this and look at the log that I write out to in afterRenderRepsponse, it shows that image1 (which shows up as the default image I set at design time) and image3 (which does not show up which I set at run time using image1's value) both show the nogo.JPG image from the resource directory while image2 (that I set at run time to be bike2.JPG) is showing up as empty
 
This is really getting frustrating, and I would greatly appreciate a small tutorial from the JSC staff on just how you need to go about doing this. given that this is so common a need, a tutorial is warranted. Heck, just clue me in on how it is done and I will write one!
 
THANKS!

How to pass column name at run time in function.

how to pass column name at run time in function as parameter.
thank in advance
pramod patel

Hello,
Using dynamic sql you can pass column name to function. well I am not getting what you really want to do ? Please write in more detail. By the way I am providing one example here. see it uses dynamic sql.
Create or replace function fun_updtest (p_columnname_varchar2 in varchar2,
p_value_number in number)
return number is
v_stmt varchar2(500);
begin
v_stmt := 'update emp
set '||p_columnname_varchar2||' = '||to_char(p_value_number)||'
where empno = 7369';
execute immediate v_stmt;
return 0;
commit;
end;
call to this function can be like this..
declare
v_number number;
begin
v_number := fun_updtest('SAL',5000);
end;

[CS4 Mac] Change PictureWidget image at running time.

Hello,
I have a PictureWidget on a panel - by default it displays a PNG file loaded from resources.
It can also display error icons when a query fails - etc: these icons are loaded from plugin's 'PICT' resources.
So far so good.
Now - when a query doesn't fail it would need to display an image stored as a 'PICT' file on a server: the query result is telling me which 'PICT' file is to be displayed in the PictureWidget.
For QXP I was using DrawPicture() to draw the PicHandle directly in the item rectangle.
Switching it to InDesign - I am looking for a recipe to achieve same result but following InDesign SDK means and spirit.
In other words - how do we change a PictureWidget image at running time in order to display a PICT files from server instead of built-in default PNG or 'PICT' resources.
Any pointer or direction to achieve this would be very much appreciated indeed.
Best regards
Patrick Perroud

How to create Edit Image in my form

hi All,
I have a form with header and detail, in my detail block i need to add Edit Image in my form. When i click on this i should be able to open one of my text column.
can any one please help me how to create new images....

Siva,
There is a different Technology Stack associated with the Enterprise Business Suite (EBS). amitphynyl is correct with the description of how to create a button with the edit.ico assigned to it, but with the EBS, you will want to speak to your DBA to get a list of all the Icons that are available as you will have more icons with the EBS than are available with a standard install of Forms Builder 6i. I would also suggest you ask your DBA to give you a copy of all the Icons so you can add them to your Forms Builder installation so they will be available to you during design of your Form.
I would also recommend that you review the Oracle Applications User Interface Standards for Forms-Based Products guide in the Oracle Applications Documentation web site to ensure your Custom Form conforms to Oracle guidelines.
Hope this helps,
Craig B-)

Dynamic Images at run-time

I have a report that I would like to display a different
image/logo depending on the user who is generating the report. Is
there a method to display a different image at run-time? Or, does
anyone have a better way rather than cloning 10 versions of the
report will a different image on each?
Thanks for any help in advance,
Kevin

Here is a sample that shows changing an image at runtime. If you are using a different version of Crystal Reports than XI R2, let me know.
