How to control the input in cell of Jtable must be number?

I want to control the character of cell or column of jtable, it must be number(0-9),
only the user type number(0-9) will show on the jtable.
how can i do that, can you give me a little example or hints?
Thanks very much!

Hi,
Your question is not that clear to me but... I believe that putting a PlainDocument class on the JTextField of the JTableCellEditor and overriding the insertString method would do the trick...

How to control (the input and output) EXE file after I call it using exec?

Hi,
I knew that I can use runtime.exec() to call one EXE file, and this works. But this EXE has two characteristics:
1. After this exe starts, it asks user to input number such as 1 or 2 onto computer screen, then press return. Then the exe will start the calculation.
2. after it starts calculation, it prints 3 columns of numbers onto the screen.
My two questions are:
1. How to use java to input the number such as 1 or 2 automatically? this EXE can not work like this in DOS command line:
C:> file.exe parameter
The parameter is the number such as 1 or 2 that I wanna input.
2. how to redirect the 3 columns of numbers from computer screen to txt file?
My colleague can solve these two questions using Mathematica. So I know that definitely there is at least one solution for it. I just can not do it using Java. This wierd exe file bothered me a lot and I really wish that I can get help from someone in java community.
Thank you!
Tony

When you call Runtime.exec, you get a Process object. (I presume something similar happens when you use ProcessBuilder.) Process has methods with names getOutput, getInput, and getError. These correspond to the standard input, standard output, and standard error streams of the spawned process.
You can read and write to the process on the streams corresponding to input and output that the process writes to the console.
[add]
In fact, you should be grabbing and reading the output/error streams anyway, because of the points raised by the Traps article. Google "Java Runtime exec traps" and you'll probably get a link to this JavaWorld article, which describes common Runtime.exec problems and how to solve them.

How to change the input language ?

Hello,
I am writing an Add-on that needs to change the input language when the user
clicks on the Item Code field ("5") in the "Item Master Data" form.
I can perform the change when I am out side of the SAP application (for example if I create a Windows Form), however I cannot control the input language of the SAP itself through code.
I even tried using Application.Sendkeys, however I was unable to send a combination of ALT+SHIFT, or at least it did not have any affect
Here is the code on how to change the input language on a Windows Form:
For Each Lng As system.Windows.Forms.InputLanguage In system.Windows.Forms.InputLanguage.InstalledInputLanguages
   sValue = Lng.Culture.DisplayName.ToUpper()
   If sValue.StartsWith("ENGLISH") Then
                    system.Windows.Forms.InputLanguage.CurrentInputLanguage = Lng
                    Exit For
    End If
Next
Any ideas ?

I am not sure I understand the problem. Anyway in B1 you change the language by
changing it from the Administration module. This raises a Application event that
is sent to all the add-ons. The event is aet_LanguageChanged and you should
then change the language handled by your add-on when you receive it.

Any ideas how to control the html color?

I've never had to do this before- but I'm trying to change
the background color of the html page that holds my master.swf on
load of an external swf... I'm not even sure as to where to begin
to look-- if anyone has any suggestions- that would be lovely...
most of the google search results are just giving me flash 4
tutorials on how to change a movie clips color... ughhh.
Thanks!

Powergroup,
You may want to post a little bit more about your intended application. I know a TCSC is a power electronic device used to vary the series impedance of power transmission lines by varying the delay angle of the thryistors in the device. If the inputs for the delay angle for the TCSC need to be updated deterministicallyyou might want to look into using LabVIEW Real-Time Software and Hardware to control the inputs.
However if project entails developing a feedback control scheme to vary the impedance of a transmission line using a TCSC based on a reference input you may be more interested in how LabVIEW would be able to develop the control scheme. I imagine you would want to take measurements to demonstrate the correctness of the TCSC controller based on this reference input which would also be a consideration.
Please post a little more about your application as it may help determine how to go about controlling your TCSC. Thanks.

If your source file is flat file, add extra three fields with blank (just add field separator say comma for each extra field) and then load. It should be ok.

How to control the measure based on the related dimension.

Hi Experts,
In order to improve performance, I have created three kinds of time tables in DB,such as Year .Month, Day.
Then import them into the physical layer in RPD, and combine them into one dimension in BMM.
Actually, it has three level fact related with three time tables,so they are also dragged into one fact in BMM,and one column will be corresponding with three column derived from different Fact table in physical layer.
So I want to know how to control the measure based on the related dimension.
For example:
when users drag the Year,Sales column, it will come from Year Dimension and Year Fact Table.
when users drag the Month,Sales column, it will come from Month Dimension and Month Fact Table.
when users drag the Day,Sales column, it will come from Day Dimension and Day Fact Table.

Hi,
Create a dimension Hierarchy, with Year >> Month >> Day Levels and
Next Double click on Year Table LTS >> click on Ocntetnt Tab >> set as Year
same way for Month LTS and Day LTS.
So now when you select year column then server canknow which LTS to hit and Hits Year LTS.

Thanks.

How to control the size of live data in Coherence?

How to control the size of live data in Coherence?
See the following statement:
Pause times increase as the amount of live data in the heap increases. We recommend not exceeding 70% live data in your heap. This includes primary data, backup data, indexes, and application data.
--Excerpted from http://coherence.oracle.com/display/COH35UG/Best+Practices

In any Java program, it is good practice to make sure your live objects leave some room in the heap for "scratch space." Without this, you will spend too much time in GC, and, in the worst cases, run out of memory. In the general case, you can see how much live data your application requires by looking at the heap used after a full GC's. For Coherence, you should ensure that live data, as you say, is under 70% of the maximum heap size.
Coherence provides you tools to help enforce this policy. [http://coherence.oracle.com/display/COH35UG/local-scheme] describes how to size limit your cache. By implementing an eviction policy, you can control what happens when a size limit is exceeded.

    button_event ?= event.

How could control the scroll events in ALV OO?

Hello experts!
I'm programing a report, inside there is a field that need time of processing. I'm using ALV OO.
I have thought that it could only calculate the field for the lines that visualize.
How could control the scroll events to calculate the field of the visualized lines?
I'm using CL_SALV_TABLE class and cl_salv_events_table to control the events, but there aren't any event to control the scroll.
best regards!

Hi Sriram,
I did view the information that you was attaching, but this don't resolve my problem. With methods get_scroll_info_via_id and set_scroll_info_via_id, we can get and put information of selection and view rows in the screen but we don't control when the user click in the scroll for advance or to back down a page.
I would like to refresh the data in ALV when the user view news rows.
I want your genial ideas.
Best regards!

If your intention is just changing the content you are passing to bpel/returning from bpel
Here is another way
just update your default created xsd files with new elements, update wsdl elements in message definition and chnage bpel code to reflect new elements in activities

How to control the size of SVG images in epub files?

There is unfortunately no support for SVG files in InDesign.
Most of my images in jpg convertes nicely, but the small ones do not.
Therefore I want to use SVG files which I have created in Illustrator.
But how do I set the size in the epub file? Right now, whatever I do, they come out too big and I don't know how to control the size.
Is there a program, like Sigil or other, that can place the image for me - I'm no html wizard you see....
