Plugin dev questions about chart

I'm develping EM plugin.
I have 3 questions now.
Would you please help me?
1. Can I make a combo box(drop down) ?
I'm trying to send the argument using select box(drop-down) to draw a chart.
2. Can I create chart dynamically?
I have to create charts dynamically by input parameter. It may 2 or 3.
3. Is it possible to make 2 kinds of data on one chart ?
I want to display 2 kinds of data using time series chart.
(For example, Player A's score, Player B's score.)

What documentation source are you using to develop your EM plugin? In regards to the UI questions you are asking, are you using the EM Reports (information publisher) framework? Your first 2 questions would not be possible to accomplish using the 11.1 extensibility framework. You should be able to accomplish your question #3 with the reporting framework or the Homepage Charts capabilities. Future releases of EM (EM 12.X+) extensibility framework should allow for EM plugin integrators to write custom UI (as you are asking about with your questions).

Question about Chart in WAD ?

Hi everybody :
i have designed a query about data for every year , and each year has some months , but not every year has integrated data for every month ,it means there have some years only has data less than 12 months.

who can give some tips ?
tks very much !

should i design a special query for this chart ?
otherwise, have other methods more convenient ?
kindly you to give me any reply !

2 small questions about charts

Hi All,
is it possible to :
1. rotate 45 degree the X Axis in flash 2D line chart ?
i tried modify the XML as in column chart but with no success.
i was ale to rotate it by migrating the svg chart into flash chart :)
2. is it possible to set the width of a chart to be 100% ?
so if i have lots of values it will expand the width page and i will need to scroll but if not it will stay in the normal page border .

Zvika,
In the custom XML find this line:
<block_names enabled="yes" placement="chart" rotation="45" x_offset="0" position="bottom" >Rotation will make it rotate.
To set the width to 100% is possible if you use a Form Region 100%. However, that will not expand the content of the region - your chart.
If you use &P1_ITEM. in your XML and set the value of your items which determine the width to something (whatever), your chart will change the size. Something like this:
<chart_area enabled="yes" x="122" y="72" width="&P1_WIDTH_ITEM." height="232" deep="0">Denes Kubicek

I have a question about japan new depriciation engine using non-japanese chart of deprication

Hi, all
I have a question about link between new depriciation engine and chart of depriciation.
My client want to use US chart of depriciation as standard chart of depriciation becuase it has already standard setting like IAS deprication keys.
it means I have to create Japanese chart of depriciation by copying from US chart of depriciation(non-japanese sample(0JP))
I have a little doubt about it. In my previous project, I copyed chart of depriciation by copy from Japan sample Chart of depriciation(0JP) stored in SAP.
Is it possible to copy from non-japan sample charg of depriciation to using Japanese new depriciation engine? I worried some errors will occrues if I do not use sample chart of depriciation(0JP) .
If I need to use sample Japanese chart of depriciation, please give me the idea why I need to use Japanese sample chart of depriciation. I want to know the examples of non-Japanese asset accouting consultants who have working experience in the area.
Thank you.

Hi, Narasimhulu
Thank you for your support.
My client use one COA to all over the world. And not only Japan, other country aslo use the COD which is copied from that of US. Basic reporting line is for USGAP. I will customize 2 depriciation ares, one for US GAP and another is JGAP. No need to create TAX realted customize. It means it enought only adding Japanese new depriciation keys to Current US COD. No need to add more Japanese local requirements.
In this case, I want to know follwoing point.
I know COD controll depriciation keys, but I want to know more detail about COD, what kinds of controls COD do. What is Japanese local requirements. Why better to use COPY of JP COD.
Thank you.

Questions about acrobat sdk plugins...

Can a plugin developed for adobe acrobat professional 9.0 extended with acrobat 9 sdk, run in adobe acrobat professional 8.0, 7.0 or previous versions?
I try to do that, and a error ocurs.
And the other one, is not about the plugin itself, but about an option of acrobat professional 9.0 extended . It's possible to edit a pdf, add annotations.. with acrobat professional 9.0 extended when the pdf is open in a browser view?
I try, but the options to do that were not available like "advanced editing".
Thks,
César

No. You must use the version of the SDK for the LOWEST version of Acrobat you wish to support.
A plugin is not limited between browser and stand-alone - you can do the same things in both.

Question about the programming of a legend

Hello everybody,
I have a question about the programming of a waveform's legend. I
already asked here in this forum about the legend programming (03)
months ago.
I went satisfied but I ve just noticed that this code
(See Code old_legend_test.llb with main.vi as main function) operates a
little different from my expectances.
Therefore I have a new question and I want to know if it
is possible by labview programming to plot and show, on a waveform
chart, a signal with activ plot superior to zero (0) without to be
obliged to plot and show a signal with activ plot equal to zero (0) or
inferior to the desired activ plot.
I give you an example
of what I m meaning. I have by example 4 signals (Signal 0, 1, 2 and 3)
and each signal corresponds respectively to a channel (Chan1, Chan2,
Chan3, Chan4). I want to control the legend (activ plot, plot name and
plot color) programmatically. Is it possible with labview to plot signal
1 or 2 or 3 or (1, 3) or (2,3) or (1,2,3) or other possible combination
without to active the signal with the corresponding activ plot zero
(0)?
Let see the labview attached data
(new_legend_test.llb with main.vi as main function). When I try to
control the input selected values again I get them back but I don't
understand why they have no effect on the legend of my waveform chart.
Could somebody explain me what I m doing wrong or show me how to get a
correct legend with desired plots? Thank by advance for your assistance.
N.B.
The
both attached data are saved with labview 2009.
Sincerly,PrinceJack

Hi
princejack,
Thanks for
posting on National Instruments forum.
The behavior
you have is completely normal. You can control the number of row displayed in
the legend and this rows are linked to the data you send to your graph. Thus,
if you have 3 arrays of data, let say chan1, chan2 and chan3, you can choose
which data you want to display in your graph using the property node (Active
plot and visible). But for the legend as you send 3 plots there is an array of
the plot name [chan1, chan2, chan3] and you can display 0, 1, 2 or 3 rows of
this array but you cannot control the order in this array! So, to be able to
change this array you have to only send data you need to you graph. I'm not
sure my explanations are clear so I have implemented a simple example doing
that.

Questions about Mapping GL Accounts to Group Accounts

Hi,
I have some questions about mapping gl accounts to group accounts while configuring OBIEE APPS 7.9.6.3 with EBS R12 as a source:
FIRST QUESTION.-
For file file_group_acct_codes_ora.csv, I have the following accounts from my customer:
101101 - Caja Administrativa
101102 - Fondo Revolvente
101103 - Caja de Cambios
101104 - Efectivo en cajero
This group of accounts is named CASH, now my customer said that this group begins in 101101 and ends in 101199 but in this moment only have this 4 accounts in GL, the rest of the accounts, I mean 101105-101199 are not used right now, they are gonna used in the future.
So, my question is, in file_group_acct_codes_ora.csv how I need to put this group:
In this way:
CHART OF ACCOUNTS ID,FROM ACCT,TO ACCT,GROUP_ACCT_NUM
50308,101101,101104,CASH
Or in this way:
CHART OF ACCOUNTS ID,FROM ACCT,TO ACCT,GROUP_ACCT_NUM
50308,101101,101199,CASH
I mean, is there any problem if I use the second way, or is necessary to do it in the first way, and why?
SECOND QUESTION.-
For file file_group_acct_names.csv, when I update with a new group of accounts, is there any rule or size boundary for GROUP_ACCOUNT_NAME?
THIRD QUESTION.-
For file_group_acct_names.csv, what is the value in column LANGUAGE? I mean, is EBS language?, DB language?, server language?
I hope that someone can help me, because I need to clarify this and don't do the first full load and this load ends with error because of this.
Regards,
Arnulfo

I'll take some broad swipes at this and let the smarter people come fill in the details.
We have a true 1:1 setup in our office and have moved to PHDs as a means of protecting against downtime. The thinking is that we will have a spare machine lying around with our base installation ready to go. If a user's machine fails we'll replace it with the spare machine, let it sync the user directory from the server, and we're back in business. It's no substitute for a real backup system, but it potentially avoids having to run a restore from your backups. It also reduces network traffic compared to plain networked homes, and still lets your users work if the server goes down, but provides the benefits of centralized management. John DeTroye wrote a nice article about this.
If you've already got data on your "client" Mac you will need to move it onto the server. PHDs will download data from the server to the client on the first sync, but will not upload a complete home directory from the client to an empty directory on the server. You'll find some posts in this forum discussing how people have gone about migrating data prior to that first sync.
WGM allows you to establish exclusions for stuff you don't want to sync.
One thing to watch out for in the scenario you describe is the so-called "rabbit effect." Assume Bob uses Mac1 as his primary machine. If one day he logs into Mac2 his home directory will be downloaded to Mac2. Once he returns to Mac1 he'll still be cluttering up Mac2 with his data. If he logs into Mac3 the next day and Tom and Sue are also periodically logging into different machines, you can see how you'll end up with a mess pretty quickly.
Hope this helps.

Question about Quality Gate Management

Hi Solman profis,
I have questions about the transport requests in QGM.
My Solution Manager is 7.1.
I have a Solman project, in which I activated QGM and created a Change and created two transport requests (one workbench, one customizing) attached to it, .
I'm little bit confused by the concept.
My questions are:
1. Why I cannot see the transport requests that I created previously in the DEV system manually? If it's normal, for which reason is this designed like this? If it's not normal, how can I configure to see those requests?
2. What is the difference between the Change here in QGM and the Change in ChaRM?
3. In practice, how should the transport requests be created? By the developer in DEV systems, or by the responsibles in Solution Manager Workbench (Change Management Workbench)?
Thanks a lot!

For the 3rd question, I think TRs should be created in Change Management Workcenter, is it the correct process?
For the other questions, can somebody give some input?

Basic questions about programing for J9 VM

I need to create a java application to run on a Pocket PC 2003 OS and I'm limited to using IBM's Websphere J9 Virtual Machine. I'm new to using java in this capacity and therefore have lots of questions which I'm guessing are pretty basic. Despite my best efforts, I've found very little to help me online. Below are a couple questions I have that I'm hoping someone can help me with. Even better, if you know of any resources that could help me with these and other questions, I'd love to have them. Thanks in advance.
1. I'm using standard AWT for the GUI but I'm having problems getting frames, dialogs, etc., to come up in anything less then full screen. setSize() and resize() have no effect, even if I extend the frame and override the setMinimumSize, setPreferredSize, setMaximumSize methods. What do I need to do to get a child window to appear in something less than full screen?
2. I'd like to be able to add menu's to the buttom toolbar (with the keyboard) but have no idea how I would add something to it. Can someone point me in the right direction?
3. When my application gets an iconified event I go ahead and call a System.exit() to exit the application. This doesn't kill the java VM though, which continues to run in the background (taking up plenty of memory). If I run my application using the J9w.exe so that it runs without the console, then not only does the VM continue to run, but I have no way to stop it (the running program list can't see it). Since each time I run my application it starts a new VM, it only takes a couple of times before I'm out of memory and have to do a soft reset of the PDA to make things right. Can I kill the VM when I kill my application?
4. I learn best by looking at example code, but have been unable to find any code people are running on J9. I have the GolfScoreTracker installed and running on my PDA, but the jar file contains only the classes. Since it's supposed to be a demo, I had hoped that the source code would be included, is that hoping too much or is the source code available somewhere? In addition, if you know of any applications out there with available source code that are known to run well on a PocketPC J9 environment I'd appreciate the link.

Hi there, I saw your questions, im currently developing a java pocket pc application as well and here's what i go so far:
AWT seem to be hard to use on pocket pc, instead i recommend that you use SWT, which is a technology developed by eclipse. It's already installed on the eclipse plugins, you just need to download the jar and dll files for the pocket pc. They are available at: http://www.eclipse.org/downloads/index.php
I assume that you already have the J9 working on your device. So you only need to copy the SWT.jar file and the swt-win32-3064.dll to the folder containing the .class files on your device.
Now, on your java IDE(im using eclipse) Add the SWT.jar library to your project which should be on C:/eclipse/plugins/org.eclipse.swt.win32_3.0.2/ws/win32/swt.jar or something like taht depending on your eclipse root.
Now you are ready to code some SWT, here is a sample program from Carolyn MacLeod, i modified a few things so it could run on the pocket pc but it's almost the same. Once you coded in eclipse run it, then copy the class file from your desktop to your device(There should be like 4 or 5 classes like sample.class, sample$1.class etc. copy all of them) where you put the jar and dll files(If program does not run you may try to rename the dll file for swt-win32-3050.dll instead of 3064.dll). Now after you have everything set up you need to create the lnk file in order to run the program. On your desktop create a new textfile and write the following on it:
255#"\Archivos de Programa\J9\PPRO10\bin\j9w.exe" "-jcl:PPRO10" "-cp" "\My
Documents\Java\swt.jar" ;\My Documents\Java" sample
Paths depend on your install, and the place where you put your classes and jar file. path for j9w is usually "\Program Files\J9\PPRO10\bin\j9w.exe", and the last word should be the classname.
Currently this form only displays an image on a canvas, click on the browse button and choose a pic and it will display on the canvas. Im trying to connect the form to an oracle database but no success yet on the device.
Hope it helps, if you have any questions about the code or something, and I know the answer, please feel free to ask.

Question about firefox permissions for sites

i have a question about sites permissions
in google chrom it is easy to set permission for each site like (java, flash plugin, image , ...)
http://i58.tinypic.com/nl66v9.png
but i prefer to use firefox
is there any addon or something else to have this options in firefox ?

You can inspect and manage the permissions for the domain in the currently selected tab via these steps:
*Click the "[[Site Identity Button|Site Identity Button]]" (globe/padlock) on the location/address bar
*Click "More Information" to open "Tools > Page Info" with the Security tab selected
*Go to the Permissions tab (Tools > Page Info > Permissions) to check the permissions for the domain in the currently selected tab
You can inspect and manage the permissions for all domains on the about:permissions page.

Question about clear page and reset pagination

Hi,
I have a question about clear pages and the reset pagination in an URL. What is the reason why a clear page doesn't also trigger a reset pagination on the pages which are cleared?
I can't really imagine a business case where it makes sense to clear all data of page items on a page and don't reset the pagination of reports on that page which probably use a page item in there where clause...
The drawback of this behavior is that a developer always has to set the reset pagination checkbox when he clears the target page and the even bigger drawback is that if you specify other pages to clear, you can't reset pagination for them, because reset pagination only works for the target page.
Thanks for your input.

I got an answer and I replied with a question about the answer, does no show in unanswered

I got an answer and I replied with a question about the answer, does no show in unanswered questions. I guess replying was not the way to get another anwer, How do I do that?
He said - Certain Firefox problems can be solved by performing a Clean reinstall. This means you remove Firefox program files and then reinstall Firefox.
I want to know - Will I still have my bookmarks, history, addons, plugins, etc.? I do not know what plugins and such that I had. What about my pinned tabs and my tabs that where open.
More information - When I try to start Firefox I keep getting the message that I need to restart my computer in order to complete a previous update attempt. I had Sweetpacks on my PC and I do not know where it came from, it took over my home page in Internet Explorer and Ithink caused the issue with Firefox.
Should I do the clean install or try starting Firefox now.

Could you please stay in the thread where you posted the question and reply there instead of opening a new thread?
Locking this thread, so please continue here:
*[[/questions/968194]]
See also:
*[[/questions/968222]]
You won't lose bookmarks and other data in the Firefox profile folder as long as you do not remove personal data in case you uninstall Firefox.
See also:

You can open the Properties of the Firefox desktop shortcut via the right-click context menu and check the "Compatibility" tab. 
Make sure that all items are deselected in the "Compatibility" tab of the Properties window.

Question about OSM Notification

I have some questions about the jeopardy notification.
As of current, I know only how to set user and email server to send out the notification,
but I want to know about how to create the email message content?
I've been trying to find the answer about this but still haven't found any.
So my questions are:
- Is it possible to create/define email message content?
- In case possible: How could I do to create/define the message content?
- Any reference which could be more helpful to study about this?
It'd be pleased if you could give an example of the email & the content?
Please help.

Hi,
If you refer the Concepts Guide of OSM documentation, it says
About Sending Notifications in Email
You can deliver notifications in email. The email message consists of the same information that is displayed in the Notifications window in the Task Web client. You cannot customize the message or add information to it.
So, try out an automation plugin Java Code combined with an events/jeopardy which can send email with specified content.
Thanks

Some question about communicating the usb RAW device

I have some question about USB communication: I want to make my VI communicate
TI-DSP by USB, now, the driver of USB on DSP have done, and there are a test
program writen by VC and a driver fold(with a .inf and a .sys files), when I
install the driver and run the test program, the driver program on DSP run
regularly. And then I want to program a VI which have the same function as the
test program, so I unload the driver on PC firstly, then install the DSP in
NI_VISA according to "Using NI-VISA 3_0 to Control Your USB Device - Tutorial -
Instrument Drivers". When I sent the standard control request using the VISA test panel, the status below happened. I don't know what wrong with my step.

1、Do I have to install the .sys driver file in VISA? How can I install the driver file without losing the device in MAX?
2、Someone told me it must be done by calling .dll fies in LV, but I want to know if LV can program the function directly without calling .dll file?
Thank for any reply~~!

5us        56.2.0 PS: the
software I use to capture the data is BUSHOUND 1、Do I have to install the .sys driver file in VISA? How can I install the driver file without losing the device in MAX? 2、
Someone told me it must be done by calling .dll fies in LV, but I want
to know if LV can program the function directly without calling .dll
file?
This thread
contains already a related answer and explains what a sys driver is.
While you could theoretically use the Call Library Node to call all the
necessary Win32 API kernel functions to connect to a device driver,
this would be very cumbersome and not doable without a real good
understanding about C programming. Writing an interface DLL instead
won't need more C programming knowledge at all but will give you a
clean interface to that device driver which eventually could be used in
other programming environments as well.
