How to use messages in WebDynpro-ABAP

Hi,
How to use messages in WebDynpro-ABAP.
Does it has any class to manage messages like IWDMessageManager or we can just use standard SAP Message types.. like E,W,X,I,S..
I hope it have a message container to display messages.
Thank U for Ur time.
Cheers,
Sam

Hi Sam,
U can hard code the message or u can use the Assistance class's text elements to store the messages.
1) Code to display hard coded message:
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = "Enter the correct Connection ID"
element = elem_flightinfo
attribute_name = 'CONNID'.
2) Code to display message from text element of assistance class:
lv_text = wd_assist->if_wd_component_assistance~get_text( key = '002' ).
report message
CALL METHOD l_message_manager->report_attribute_error_message
EXPORTING
message_text = lv_text
element = elem_flightinfo
attribute_name = 'CONNID'.
Where Message "Enter the Correct Connection ID" is stored in Text Element with key '002'
Hope this helps,

Do I need sample clearance to use instruments in my songs

Do I need sample clearance to use software instruments in my songs

If you need to use DAQmx, then of course you need to use an NI card. But you are thinking of this in the wrong order. Do you need to use an NI card to communicate with teh FF device? You can, but there are probably other cards out there as well. If you use an NI card, it probably won't use DAQmx but other things such as VISA since it is probably more like a serial protocol than a DAQ device. If you use another brand, then you use the that company's drivers with it.
I just realized you posted in the wrong forum. This forum is for requesting files to be converted between different version of LabVIEW.
You should be posting elsewhere. Possibly Instrument Control (GPIB, Serial, VISA, IVI)

How to use Class "CL_GUI_CHART_ENGINE" in a abap program ?

Hi Guys,
I want to display data in my internal table in the form of a Graph using class "cl_gui_chart_engine".
I had a look at sample program given by SAP - GRAPHICS_GUI_CE_DEMO but need some help to understand how can we use our own data to be displayed in the graph ? Basically what I am looking for is that where we need to do the changes in creation of XML file so that we can pass our own data ?
( perform create_data_demo using l_ixml_data_doc)
Could you please help me with some sample code or pseudocode ?
Thanks
Ashwa

Thanks Kai,
I had already done the same thing and got the required output.
Populate X-Axis ( Categories )
LOOP AT ITAB.
Populate Categories
    l_element = p_ixml_doc->create_simple_element(
              name = 'C' parent = l_categories ).
    l_element->if_ixml_node~set_value( itab-value).
ENDLOOP.
Populate Y-Axis ( Values )
LOOP AT VALUE_TAB.
   l_element = p_ixml_doc->create_simple_element(
             name = 'S' parent = l_series ).
    l_element->if_ixml_node~set_value( value_tab-value).
ENDLOOP.
I am now trying to find the ways to change the default layout of the graph. I guess it should be done in "perform create_custom_demo using l_ixml_custom_doc." . I want that my graph should be displayed as lines instead of bar's.
Once I achieve this I will share my findings along with sample code with the community.
I wish I could get some documentation on class "cl_gui_chart_engine" and interfaces like "if_ixml_document".
Thanks
Ashwani

How to use class.getResource() to create an ImageIcon

Hi,
I am well acquainted with creating and using ImageIcon icons using the ImageIcon constructor
and putting the image file in a folder called Images which is at the same level as the
bin and src folders.
I discovered a demo program, LayeredPaneDemo, that uses class.getResource() to create
an icon and found that in my eclipse version, the icon's image file was not found when
I used the original getResource() call but the icon was created when I used the ImageIcon
constructor.
I posted on JavaRanch and eventually realized that the image file needed to be with the
.class files, so I moved the Images folder under bin and getResource() works fine and I'm
happy.
However, I have three questions for you.
One poster on JavaRanch told me that it's better to use getResource() rather than the
ImageIcon constructor for distributing an app (I'm not distributing anything but want
to do it all correctly).
Do you agree with that or can I safe keep using the ImageIcon constructor?
Another poster told me he doesn't think it's safe to leave the image file in bin because
it might be lost during the build in eclipse and that there is a way to have eclipse copy
the files to bin during the build which should mean that I can leave the images folder at
the level of bin and src.
Do you agree with that?
If yes, how do I get eclipse to copy the file during the build?
P.S.
Before I posted on JavaRanch, I put the Images folder at every level of the project's
directory as shown in eclipse (which is why I missed the bin folder until JavaRanch
whacked me upside the head) and getResource() still didn't work.

The contents of the Java Source folder are compiled if they're source files, copied otherwise (assuming no filter's been put in place to prevent copying), so your images belong under a source folder.

How to use classes CL_DOCX_*

We have a need to use word 2007 OOXML classes all of which start with CL_DOCX*.
Basically what we are trying to do is take a DOCX files (File 1 & File 2) saved by MS WORD 2007 application and replace the header of File 1 with the header from File 2.
The basic functionality described above is working fine. However the same is not working when the header from File 2 has an IMAGE embedded in it.
We found several word 2007 OOXML classes in the system (all of which start with CL_DOCX*), but couldn't find usage for these classes anywhere in the system or SDN or OSS Notes etc.,
Just wondering whether anyone used these classes in their development environment and whether they can share this information here?
Any help in this regard is highly appreciated.
thanks,
-Sreenath

Which NetWeaver release are you using? The whole OOXML seems to be evolving within EhPs.
You'll find examples how to use the framework in the Unit Tests of class CL_DOCX_FORM - so have a look at those classes. For me those test code runs fine.

Hi Greg.I think I was not able to clear my problem properly.Let me try this time again.
What I wanted to do was that in the below written code I have the full access of the id=panel1 in the script tag .This works properly.
<?xml version="1.0"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
import flash.display.Sprite;
import mx.core.UIComponent;
private function addChildToPanel():void {
var circle:Sprite = new Sprite();
circle.graphics.beginFill(0xFFCC00);
circle.graphics.drawCircle(0, 0, 20);
var c:UIComponent = new UIComponent();
c.addChild(circle);
panel1.addChild(c);
]]></mx:Script>
<mx:Panel id="panel1" height="100" width="100"/>
<mx:Button id="myButton" label="Click Me" click="addChildToPanel();"/>
</mx:Application>
This above functionality when I tried to do using class Outside the code ,its not working !
Here is with the package:-
But suppose I make One package
package
import flash.display.Sprite;
import mx.core.UIComponent;
class getPanel extends Sprite
public function addChildToPanel():void {
var circle:Sprite = new Sprite();
circle.graphics.beginFill(0xFFCC00);
circle.graphics.drawCircle(0, 0, 20);
var c:UIComponent = new UIComponent();
c.addChild(circle);
panel1.addChild(c);
}//class
}//package
Now in MXML
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Script><![CDATA[
import getPanel;
]]></mx:Script>
<mx:Panel id="panel1" height="100" width="100"/>
<mx:Button id="myButton" label="Click Me" click="getPanel.addChildToPanel();"/>
</mx:Application>
So My problem is that this code doesnt do anything.
Neither the addChild function is working in it ,Nor the Panel1 is accessible here.
Can u pls help me here.
Thanks

How to use classes in Actions tab

Hello guys!
I'm just a beginner so i'm sorry for my stupid question.I'm developing a game in which movie clips in our case people have their own schedule.I have multiple screens and so i want to be able to set their locations and make them invisible on other screens(rooms)they're not currently at.The trouble is i can't use variables from Actions in my class,neither can i use classes in my Actions.Can anyone tell me how to export classes into Actions code?
Here is my code:
var currentlocation;
var currentscreen;
if (person.currentlocation!==currentscreen){
person.visible=false;
btn.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler);
function fl_MouseClickHandler(event:MouseEvent):void
          currentscreen = "classroom";
          classroom.visible = true;
          playroom.visible = false;
btn_2.addEventListener(MouseEvent.CLICK, fl_MouseClickHandler_2);
function fl_MouseClickHandler_2(event:MouseEvent):void
          currentroom = "playroom";
          classroom.visible = false;
          playroom.visible = true;

Your problem/question is not clear to me. If you are getting errors you should include the error messages in your posting.
Could the problem arise from using a variable that is not defined?
currentroom = "playroom";
I do not see currentroom defined as a variable anywhere. There is a currentscene variable though.

How to use classes from an existing outside library ?

Dear People,
I added a library to use classes already built.
In JBuilder7 I went to Tools | ConfigureLibraries
and added the objectdraw library. At the left when I look in the
directory structure under User Home is "objectdraw" so I did
add the library correctly but when I put in the coding a try
to run it, the error messages say:
"MakeBox.java": Error #: 200 : <identifier> expected at line 8,
which is the line : public void MakeBox()
The entire code is :
package stan_e_makebox;
import objectdraw.*;
import java.awt.*;
public class MakeBox extends WindowController
void public MakeBox()
public void onMousePress(Location point)
new FilledRect(40,80,30,20,canvas);
public static void main(String[] args)
new MakeBox();
Thank you in advance
Stan

oo sorry,
this is the constructor i assume, so should be
public MakeBox()
