How to change the case structure to string input?
Hi,
I have the inner case structure that it will decide to set "DC Voltage" or "DC Current" mode. The "Output Function" contained the selection of function "DC Voltage" or "DC Current". So far it only work with DC Voltage not DC Current. My question is how do I change the case structure to string selector? When the output function is selected to DC Voltage then the case structure is selected DC voltage case. Please help Thanks.

You don't really need to convert the value to a string? The problem is that the value of the individual ring items are not 0 and 1, as you assumed. The values generated by the controls are:
DC Voltage: 1006
DC Current: 1007.
You can find this out by viewing the properties for the "Output Function" and going to the "Edit Items" tab.
So, all you need to do is change the 0 to 1006 and the 1 to 1007 for your case items.
By the way, your sequence frame serves no purpose.

Thank you very much,
ChristianThere is a workaround to move from 1.5 version to the older 1.4 version. But this could be specific to the browser setting the JRE version.
Excerpts from sun docs:
However, a user can still run older versions. To do so, launch the Java Plug-in Control Panel for the older version, then (re)select the browser in the Browser tab.
Example:
Assume you are running on Microsoft Windows with Microsoft Internet Explorer, have first installed version 1.4.2, then version 5.0, and you want to run 1.4.2.
Go to the j2re1.4.2\bin directory where JRE 1.4.2 was installed. On a Windows default installation, this would be here: C:\Program Files\Java\j2re1.4.2\bin
Double-click the jpicpl32.exe file located there. It will launch the control panel for 1.4.2.
Select the Browser tab. Microsoft Internet Explorer might still appear to be set (checked). However, when 5.0 was installed, the registration of the 1.4.2 JRE with Internet Explorer was overwritten by the 5.0 JRE.
If Microsoft Internet Explorer is shown as checked, uncheck it and click Apply. You will see a confirmation dialog stating that browser settings have changed.
Check Microsoft Internet Explorer and click Apply. You should see a confirmation dialog.
Restart the browser. It should now use the 1.4.2 JRE for conventional APPLET tags.
Details are here
http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/jcp.html
My system (Windows XP) has the version 1.5_09 set as the default. However i just installed JRE 1.5_06 and would like to revert back to _06 as the default JRE..
Will update if i find more information -

How to change the long in to string
Hi
In my program i get the long value as input.
Then i send this long value to one method for testing which accepts the argument as String.So i have to change my long in to string then i pass it to the method.
can anybody tell me how to change my long in to string?
Thank you so muchThere's probably a method java.lang.Long.toString.
If not, there's probably something a lot like it in either the Long or String classes.
I'll leave you the pleasure of looking it up in the API docs. -

How to change the inventory structure
I am now running Oracle 11.0.3, 15 users, AP,AR,GL,INV,OE and PO
on MS NT platform. The existing inventory item is using 10
segments and 20 characters which is very difficult for data
entry. Thus I would like to change it to 1 segment and 10
characters. I want to keep all transactions (all data) in AR,AP
& GL and I would give up (purge way) all data in OE, PO and INV
after restructuring as it has different structure on item master.
One way is to create a new instance/database, re-configure the
AR, AP & GL setting and convert all data from AR,AP & GL, then
configure the new item master structure and re-enter about 500
items. This will take too much time (20-30 mandays).
The other way is after the month-end closing, disable all 10
segments, purge way all transactions in INV, OE & PO. Then
create a new segment with 10 characters and re-compile it. I
would prefer this method as it has minimum effort.
My question is whether the 2nd method is feasible or not? Will
there be any problem in using this method?You don't really need to convert the value to a string? The problem is that the value of the individual ring items are not 0 and 1, as you assumed. The values generated by the controls are:
DC Voltage: 1006

Editing Chart legends: How to change the line structure within the legend?
Hi,
I have one problem: I have several charts in Numbers and since I need to print them in black/white, colors cannot be used to differentiate between the lines. So if I have a dotted line and a solid line, the legend only shows me solid lines as line symbols, so the line structure is not reflected within the legend. Can I change that?_This question was already asked and responded._
Put a text box with the true kind of line above the one displayed automatically.

ADF Mobile: How to change the font size of an Input Text field in .amx view
Is there a way to change the font size of the input data (not the label) in a text field? Changing the font size in the Style Font/Text settings doesn't seem to do anything for the label or the value in the input text field. Is this a bug or is there a way to get this to work?
Hi Anna,
depending on the UI element there are a range of ways. (and I'm sure people will post plenty of answers to tell you how).
However, if generically the fonts in you portal/wd applications are too small, you should consider changing your theme so as to have larger texts. Otherwise you will either need to customise all your applications, or you will get quite a lot of inconsistency of presentation between your various WDA applications.
Do a search on "themes for Web Dynpro ABAP" and you'll find loads of resources.
Hope this helps,
Cheers,

How to change the flag image in language input in menu bar?
I have two languages that I have selected for regular use in my language input menu (on the right-hand side of the menu bar), and I would like to change the Spanish input flag from the Spain national flag to an Argentina flag, just for aesthetics. I figured it'd kind of be like changing the image of how the HDD looks like on the GUI (control-click, get info, copy and paste image), but I'm not sure where to start or if it's even possible. Anyone have any clues or experience with this? I may just have to make do with keeping the Spanish flag up there but just for curiosity's sake I want to know if it can be done.
There is no problem doing this if you are willing to create and install a custom keyboard layout. You can find the tool and a manual at

How to change the content of a text input?
Hi!
I would like to help me with the following
I've create and input text, for example this:
var one= sym.$("one")
one.html("Enter your answer: ");
inputOne = $('<input />').attr({'type':'text', 'value':'', 'id':'one'});
inputOne .css ('font-size', 14);
inputOne .css ('width', 350);
inputOne .css ('background-color', '#0a81fb');
inputOne .appendTo(one);
Now the user can write anything in this input text.
The corret word that the user has to write is "correct"
so i use an if to validate it
if (inputOne.val() == "correct"){
alert ("good")
}else {
// HERE IS MY PROBLEM!!! What i need to do is: if the user types a wrong answer i //need to show him the correct answer in the input text.
I hope you can help me.
Thank's =)sym.$("NameofInputTextElement").html("What you want to change the text to");
Have you tried this yet?

How to change the Element structure of a DefaultSyledDocument
Hello,
I'm trying to override the insertUpdate method of DefaultStyledDocument so that I could build my own Element structure by adding my own BranchElement- and LeafElement-s. If I examine the Element hierarchy everything seems OK. But when I use my document in a JTextPane. I get the error Exception in thread "AWT-EventQueue-0" javax.swing.text.StateInvariantError: GlyphView: Stale view: javax.swing.text.BadLocationException: Invalid location (I add the whole dump at the end of this message), whenever I add a new line to the document (to test this compile and run the included code and press then newline after the 'He' in 'Hello'. I suspect that the error is caused by the fact that the view hierarchy is not updated correctly but I'm not sure. To be honest I have searched for a while for some example code, explaning how you can make your own element hierarchy in a DefaultStyledDocument (without using ElementBuffer), but to no avail.
Can any of the Text gurus here shed some lights on my code and see what is wrong with it or point me to some example code.
Thanks a lot in advance.

Now I read from uncle_alice that the text package from swing is not ment for that and that I need to write my own JTextPane and my own document and view.
Can you explain what you mean by "writing my own JTextPane and View and Dcoument".
My own Document I already have in order to provide SQL-highlighting.
But what exactly do you mean by suggesting to write my own View! Whoever uses JTextPane doesnt really have much to do with its view. Can you give me a hint as I am completely stuck with an Exception : "javax.swing.text.StateInvariantError: GlyphView: Stale view: javax.swing.text.BadLocationException: Length must be positive"
can you pinpoint the standard text-package's deficiency? it lacks what? what is the best work around?

How to change the format of a decimal input field?
Hello,
When creating an input field of type decimal the numbers appear at this format: 123,123.
Is it possible to disable this format and let the numbers to be displayed like this: 123123 ?
Regards,
RoyHi Roy,
Create a simple type in local dictionary of built in type integer. In the representation tab you can give any format you want. For your requirement you can give ####### in the format. You can also try other formats like ##,#### etc. Now create a context attribute and in it's type property give the simple type you have created by selecting the appropriate folder. Now map this attribute with the input field.
Regards,

I need an execution of commands after the reply from the instrument matches with the string I provided for that i used true or false string match VI on which the true string the matching command and the string is the reply from the instrument. And I put the further executionable commands in frame after frame of sequence loop in the true of the case structure. Amd finally I given all the output strings to the concatenate string to get all the replies as one loop. But when I execute the program the desired result is not available. So kindly please help me to overcome this problem.

basic serial with changes.vi 24 KBYou VI makes absolutely no sense and I would recommend you start with a few simple LabVIEW tutorials before trying to tackle this.
What is the point of the FOR loop with 1 iteration, it might as well not even be there, same difference.
Why is there an abort primitive in the FOR loop, this mean the program will unconditionally stop abort before any downstream code will ever go into action. The program will never get past the FOR loop.
You created a circular data dependency and LabVIEW inserted a feedback node automatically, making things even worse. (see also)
You need to learn about dataflow, execution order, and data dependency.
You need to learn about the various types of tunnels (plain, autoindexing, etc.)
There is a tremendous amount of duplicate code. Large code sections are the same, differeing only by a string. You should only have one copy of that code inside a proper state machine. Have a look at the design templates and examples that ship with LabVIEW.

How to change the type of Case selector
Hallo,
I'm running LV 6i on NT4.0.
I have a Case structure with several strings as cases, lets say stringA
(Standard), stringB, stringC, stringD and so on.
So my Case selector is of type string. That works fine so far.
Now I want to change that structure from StringType to EnumType, so I would
have cases CaseA(Standard), CaseB, CaseC and CaseD. So I want to change the
slector type to Enum and associate the former string cases to Enum cases.
1. I wired an Enum constant to my string selector, and tried to assign a
case for each enum, the machine crashes.
2. I duplicated each string case and tried to assign the duplicated to the
enum, the mashine crashed.
Is there a way to do this, without deleting the case structure, or starting
a copy paste orgie?
Oliver FriedrichSomething very strange is going on. I have tried what you explained in V6.0.2 running under W2K and all is well with the world. Can you post the VI that's doing it and let me play with it? Perhaps I might see something. In the mean time, it might be that the VI is corrupted and you'll have to rebuild it. This is a very rare circumstance with LV, but it can happen--especially when the computer crashes.
Have you upgraded to 6.0.2. If not that's another thing to try. The upgrade is free and can be downloaded from NI's website.
