Invisible string

I have magic string magicString , it prints the same as ordinaryString. I want to catch magicString in my program and if it is magic string println: " he-he, I won, magicString" :)
How can I find invisible characters in magicString?

Well it printrs as:
String ordinaryString =" ";
System.out.println(ordinaryString);
System.out.println(magicString);
//the same output but magicString.equals(ordinaryString) == false

How to handle an invisible character in a string?

Hi,
I have an interesting situation-
select bac_person_id, length(bac_person_id) from bkmap_personid_stg where BAC_PERSON_ID like '%27136317%'
The result is -
BAC_PERSON_ID|LENGTH(BAC_PERSON_ID)
27136317| 9
I don't know what is the invisible character here?
It is certainly not a blank character as trim is not working -
select * from bkmap_personid_stg where trim(BAC_PERSON_ID) = '27136317'
no records!!
But substr does give me the resullt -
select * from bkmap_personid_stg where substr(BAC_PERSON_ID,1,8) = '27136317'
How can I know which is the last character? and How to handle it?

How can I know which is the last character? and How to handle it?You use the DUMP() function in SQL in order to see the actual content of the column.
E.g.
select DUMP(bac_person_id) from bkmap_personid_stg where bac_person_id like '%27136317%'
The decimal character values will be displayed - enabling you to see where and what control characters characters exist in the string value for that column.

Make string of MCs invisible/visible...

I have a map of states state when a particular state is clicked on, the fla centers on and zooms to that state. When you click on a state a unique ID is pulled from an xml. Using this ID, I can then call all the counties that are part of this state through the county's xml which is also loaded on my stage.
For example if I click on Arizona, it zooms and I get a trace of all the instance names of the counties within Arizona.
//call all instance names of Arizona counties
cldcnfips=(cntXml.Records.Record.(STATE_FIPS==cldstfips).afips.children());
trace(cldcnfips);
//The trace looks like this
a04001a04003a04005a04007a04009a04011a04012a04013a04015a04017a04019a04021a04023a04025a04027
//where "a" is the first character in each county's instance name
One of my first lines of code makes my counties invisible.
//dont show the counties yet
this.cnt.all_cnt.visible=false;
What I'd like to do is make just the called state's counties visible on zoom.
Since I've created a var which is a string of the counties I am interested in, can I specify that just those counties become visible? I've tried this code but it does not work
this.cnt.all_cnt[cldcnfips].visible=true
I am worried that the string I am pulling as a reference for those counties (cldcnfips) might not work for calling those instances.
Does anyone have any suggestions or insights?

The only hitch is making all the states visible when i tween over to a new state...
For example.. This code is the final step in my tween.. It scales the parent mc and makes the state invisible.. It is rerun everytime a select a new state.
function zoomhide(){
          cnt.scaleX=scprop;
          cnt.scaleY=scprop;
          cnt.all_sts[calledfips].visible=false;
What code can I use to make all state visible so then when i rerun this function, only the selected state is invisible..
I tried placing
cnt.all_sts.visible=true;
Before zoomhide runs but this does not work.. If you'd like to see the whole function that is powering the zoom, tween and scale, here it is..
function ststwn(e:MouseEvent):void{
     //I tried using this to make everything visible before making the selected state invisible
        this.cnt.all_sts.visible=true;
     var calledfips:String;
     calledfips=stsXml.Records.Record.afips[e.currentTarget.ivar];
     //create vars for x,y cordinates of clicked county (child)
     var calledx:Number;
     calledx=(cnt.all_sts[calledfips].x);
     var calledy:Number;
     calledy=(cnt.all_sts[calledfips].y);
     var goto:Point=new Point(0-calledx,0-calledy);
     TweenLite.to(cnt.all_sts,.5,{x:goto.x,y:goto.y});
     TweenLite.to(cnt.all_cnt,.5,{x:goto.x,y:goto.y});
     TweenLite.to(cnt.stsout,.5,{x:goto.x,y:goto.y,onComplete:twnn});
     var wprop:Number;
     wprop=stage.stageWidth/cnt.all_sts[calledfips].width;
     var hprop:Number;
     hprop=stage.stageHeight/cnt.all_sts[calledfips].height;
     var cldstfips:Number;
     cldstfips=(stsXml.Records.Record.(afips==calledfips).STATE_FIPS);
     var     cldcnfips;
     cldcnfips=(cntXml.Records.Record.(STATE_FIPS==cldstfips).afips.children());
     cnt.all_sts[calledfips].visible=true;
     function cnnn(){
               cnt.all_sts[calledfips].visible=false;

Hi All,
I want to set invisible or blank in perticular row of table column.

I create one attribute of type WDUI_VISIBILITY. and bind visible property of that column. and code in button action is..
     DATA lo_el_context TYPE REF TO if_wd_context_element.
   DATA ls_context TYPE wd_this->Element_context.
   DATA lv_visible TYPE wd_this->Element_context-visible.
get element via lead selection
   lo_el_context = wd_context->get_element( ).
get single attribute
   lo_el_context->set_attribute(
     EXPORTING
       name = `VISIBLE`
       value = wdyn_ui_visibility_none ).
But, All buttons are invisible here. i.e., in first 2 rows buttons also invisible. But i want to invisible 3 row button only. How to do this? It is possible?
Thanks,

How do I make a JTextArea invisible to the mouse?

Consider the applet below. There is a small JTextArea sitting in the glass pane. There are 3 JButtons sitting in a JPanel that is sitting in the content pane. One is completely under the JTextArea, one is half in and half out, & the last is completely outside it (at least I hope thats what it looks like on your machine.) The idea is when you click the disable button the JTextArea is disabled and you can click on the button that's underneath it.
But it doesn't work that way. even when the JTextArea is disabled the mouse still cant click through it.
Is there some way to make the JTextArea completely invisible to the mouse so I can click through it? I know setVisible(false) on the glass panel will work but I only want it to be invisible to the mouse, not my eyes.
Thanks.

Running in invisible mode

Hi,
I have a Java Frame that i want to run in invisible mode. The problem is that i have to set it to visible first, then invisible otherwise it doesn't seem to execute. Also if i set it to ICONIFIED, the program doesn't run until it is maximized.
How can i make it so i never have to make it visible and have it still run?
Thanks for any help.

First explain what you mean by "executing a frame". Hi, this is the first time i have done anything in Java. I am trying to run this java program from a C program, but don't want to see the window pop up at all. But if i don't have the f.setVisible(true) where it is, the viewer modules, which are capturing streaming data and writing to bmp's to not work. The same is true if i set to ICONIFIED.
Thanks, hope this helps...
public static void main(String args[])
ms_standalone = true;
Frame f = new Frame(AppID.getAppID().getAppName());
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent we)
System.exit(0);
f.setSize(352, 320);
f.setLayout(new BorderLayout());
int numCams = 0;
StringBuffer concatURL = new StringBuffer();
for (int i=0;i< args.length;i++)
String arg = args;
if (arg.startsWith("-")) {
int eqidx = arg.indexOf("=")+1;
if (arg.startsWith("-num=")) {
numCams = Character.getNumericValue(arg.charAt(eqidx));
} else {
usage();
System.exit(0);
} else {
if (concatURL.length() != 0)
concatURL.append("|");
concatURL.append(arg.trim());
// create multiple viewers
Viewer cv[] = new Viewer[numCams];
for (int i = 0;i < numCams; i++) {
cv[i] = new Viewer();
cv[i].m_parameters.put(PAR_ACCESSORIES, "none");
String tmpStr = concatURL.toString() + i + ".a";

Custom control for list of string,numeric values

Hi,
I want to create a control in labView 6.1 that presents the user with a list
of string values on the front panel. The actual strings are material names
(e.g. Si, Al). With each string value would be associated a floating point
value that would then be used on the diagram for some numerical processing.
What I have done is create an array of {string,digital control} clusters,
but it looks kind of clunky on the front panel. Is there a more elegant
solution?
Thanks,
-John P

Some ideas that I use when making this kind of button:
Make an array of clusters of {string, numeric, boolean} in which:
The numeric is hidden (right click menu/advanced/hide control) (skip
this if you want the numeric to display
and
The boolean is colored TRANSPARENT and overlaid on the string. So it
it seems to the user that he clicks on the string but in fact clicks
on an invisible boolean.
Another idea is to combine the strings and booleans into one set of
buttons by making a cluster of identical booleans arranged so that
they look like an array and setting the boolean text on each button
to the desired string.
These ideas imply writing some radio button logic to generate an
index to select the desired numeric element. This is more work than it
m
ight seem
Easiest is to use events and convert the mouse coordinates into an
array index. I just made one of these and I have the code handy if
you like.

How to save string in a file with special-chars

Hello,
i´m usingthe MD5-llb to create a password.
Then i want to save this MD5-string to a file and later read it back abd compare.
Works perfect with one proplem:
Some word create a "\r" in the MD5-string and when i save this string to a file and read it back then its read back as a "\n" so that the compare is not working.
My question is: How can i save a string exactly like it is to somewhere and read it back (also invisible chars)
For example the word: heinz
is in MD5: \r\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95 (string indicator as codes display)
when i save the string to a file then i rerad back: \n\FB^\07\A6\07T\C7\D9\C2\94\AB\C9\1DS\95
I used the "write text file" and "read text file"
What do i have to use to save and read the same?
Thx
Solved!
Go to Solution.

I believe an MD5 hash is 16 bytes long. Use the binary read and write file I/O functions and specify the length of the data to be read or written.
Now is the right time to use %^<%Y-%m-%dT%H:%M:%S%3uZ>T

Can you make a column in atable invisible

Hi,
I am using the defaulttablemodel to display my table.
The data are in a vector which are sorted in descending order based on a column.
Is it possible to make a column in a table invisible.
The reason is that I need to sort my table based on a particular column but i don't want to display that column.
---thanks

Hi,
I tried to code yout example:
JTableHeader header = tblKundenInteressenten.getTableHeader();
header.setReorderingAllowed(false);
DefaultTableColumnModel columnModel = (DefaultTableColumnModel) header.getColumnModel();
int lastIndex = columnModel.getColumnCount() - 1;
TableColumn columnOid = columnModel.getColumn(lastIndex);
columnModel.removeColumn(columnOid);
header.setColumnModel(columnModel);
tblKundenInteressenten.setTableHeader(header);
...but whenever I want to get the data back like this:
DefaultTableModel dtm = (DefaultTableModel) tblKundenInteressenten.getModel();
Vector daten = dtm.getDataVector();
Vector zeile = (Vector) daten.firstElement();
String oid = (String) zeile.lastElement();
System.out.println("OID: " + oid);
I have an empty JTable in my GUI ...
what happened?

Cursor becomes invisible in JTextField after using default button

In my application there is an update screen (JPanel). I am using default button in that panel. The input field is a normal JTextField. When the update is over the cursor goes back to the input JTextField.
     Now my problem is that when I carry out update with mouse, the cursor is correctly placed into the input JTextField and is visible after the update is over. On the other hand, if I carry out the same update operation using default button (using keyboard), the cursor gets placed correctly in the input JTextfield column, but becomes invisible. If I minimize and then again maximize the window, the cursor appears back. What am I missing ? Note that I am using component.requestFocusInWindow() to get focus back to the input JTextField.

Invisible character as a separator

I have a description column (VARCHAR2 type) in a table. I need to add a separator (at a pre-determined position which is based on some logic) within the description to identify it in 2 portions. The description with the separator needs to be persisted in the table. I also need to display the description in the online pages, but without the separator.
Eg: If I use '|' as the separator then the description would be -
Databases are|useful
For the online page, I would need to use some kind of trim() in the SELECT query to remove the '|'. The trim() is going to be an overhead and I'm trying to see if this can be avoided.
Is there any special character which can be used as a separator, but doesn't have to be trimmed? Something like a character which exists in the column but is invisible in ouput of a SELECT query.

Not very sensible in data modeling and design terms. You are now forcing a single string attribute (implemented as a database column) of the entity to have an inherent structure and intelligence. And this is not supported by the string data type.
There are two basic approaches to this problem.
If the data model is correct and the string attribute is correctly modeled, then you have a rendering issue - how to display that attribute's value to an end-user. This is a client application issue. It deals with the actual rendering part of the data in the data model. It should be applying the "+split text over multiple lines+" logic.
If the data model is not correct and the attribute contains 2 "sub elements" then that should be corrected. The existing column should be redefined as 2 columns and a single mass UPDATE applied to the table to correct the contents (and create the intelligent data structure). Alternatively, the single column can be re-used and the string data type changed into a structure that supports the required intelligence that is needed. An user defined ADT (Advance Data Type) can be created in SQL to support this structure.
Keep in mind that if you hack the existing column's contents, you are now injecting structure data that is not part of the actual column value. All clients using that table and that column, will now need to recognise that and be able to determine the actual structure for that that column. This is not a sensible approach.

env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sapportals.portal.pcd.gl.PcdInitialContextFactory");
             env.put("com.sap.portal.jndi.requested_aspect","com.sap.portal.pcd.gl.PersistencyAspect");
env.put("java.naming.factory.object", "__IPcdContext__");
InitialContext iCtx = null;
String iViewID = "pcd:portal_content/ABC/1Portal/mywork/iviews/XYA_iViews/adf.ivw_ess_jspdynpage";
             iCtx = new InitialContext(env);
             IiView result =(IiView)iCtx.lookup(iViewID);
             IiViews iViewSrv = (IiViews)PortalRuntime.getRuntimeResources().getService(IiViews.KEY);
INewObjectDescriptor IVtoCreate =(INewObjectDescriptor) iViewSrv.instantiateDescriptor(CreateMethod.NEW,"par:/applications/com.sap.km.cm/components/navigation",request.getUser());
IVtoCreate.putAttribute("com.sap.portal.navigation.invisible", true);
the above method putAttribute is not apllicablt for (String,Boolean)\
Please suggest as to how can I programmatically set an Iview Visible/Invisible .

I think the property is com.sap.portal.navigation.Invisible with a capital I for invisible...
This blog has an example: Hiding portal role content with a simple iView

How to set a single tab in JTabbedPane invisible

Hello,
I want to set only a single tab invisible out of 9 tabs in JTabbedPane. I can disable the tab but not able to set invisible.
Thanking you in advance.

you may use JTabbedPane.removeTabAt(int) method as long as you don't want the tab to appear & when needed use JTabbedPane.insertTabAt(String, Icon, Component, String, int) method.
as far as i know this is only way to achieve our want. this should help you.

Afroze.

Why are the buttons invisible on WM_CREATE?

Can anybody tell me why the buttons are invisible at Program start? They are only then visible, if the client are is invalidated, in other words, if i resize/minimize the window etc.
public class Calculator extends Frame
     private Button[] button;
     private Panel p_button;
     public Calculator()
          super();
          SetWindowProperties();
          button = new Button[10];
          p_button = new Panel();
          CreateButtons();
          AddPanels();
          AddButtons();
          SetButtonProperties();
          addWindowListener(new WindowHandler());
     private void SetWindowProperties()
          setTitle("Calculator");
          setBackground(Color.white);
          setLayout(new BorderLayout());
          setSize(400,400);
          setLocation(250,200);
          setVisible(true);
     private void CreateButtons()
          for (int i=0; i<=9; i++)
               button[i] = new Button(String.valueOf(i));
     private void SetButtonProperties()
          for (int i=0; i<=9; i++)
               button.setSize(50, 50);
               button[i].setBackground(Color.gray);
     private void AddButtons()
          p_button.setLayout(new GridLayout(5, 3, 5, 5));
          for (int i=1; i<=9; i++)
               p_button.add(button[i]);
          for (int i=1; i<=9; i++)
               button[i].addActionListener(new ButtonHandler());
     private void AddPanels()
          add(p_button, BorderLayout.CENTER);

move
SetWindowProperties();
after
SetButtonProperties();
if i do that, i never can see the buttons, and this is obvoius.(your suggestion is not logical)
I am a C++-Programmer and i simply dont like the Java coding convention.
By the way, does anyone have still an idea, why the buttons are not visible at programstart?
What about:
button = new Button(String.valueOf(i));
What do you think of that statement?What should i think of ? It creates buttons with captions 1,2,3 ...
PS: At the end of line i forgot to copy the last end-block statement from the code during posting.
So if anyone tries the code, please add a " } "

You are almost correct.
The Item input is a string whose value is the name of the target plot. You can view all the plots names from shortcut menu->"CWGraph3D" group->"Properties" item->"Plots" tab ->"Plots" list.
