How to re-paint a listbox, and to display ohms symbol w/text

Hi All,
      Please help me build a string which includes characters from the Roman alphabet and the ohms symbol.  I thought I'd done this before, but perhaps not.
The plan is to populate a listbox with such strings and set cell BG color to indicate test pass/fail.  BG color of all cells can be "cleared" (changed to default) by setting the color of cell (-2,-2) (thanks again becktho!)...
... but to see the change requires listbox to be re-painted.  Was hoping for a nice way to force repaint (besides re-size/re-pos.)
Any help would be appreciated!
When they give imbeciles handicap-parking, I won't have so far to walk!

In Labview, switch to the Symbol font, then double click to make a label or comment, and type shift-W.  This makes W.
Also, unicode 03A9 is the code for ohms.

    My daughter and I both  have an iPhone and some how we share an iCloud account and she's getting all my texts and contacts. I can't find where to uncheck her phone number on my phone account so she doesn't get all my texts and contacts. Please help

    Hi Shellyk,
    Go to Settings>Messages>Send & Receive and make sure that only your personal email addresses are listed under the individual phone number.Remove the "shared" iCloud email address.
    For the Contacts, if you are syncing them via iCloud and you both have the same iCloud account, you will both have the same Contact list.

  • How to make a robot roam and simultaneously display its coordinate using other vi

    Hi i am using Cricket to find the coordinates of moving robot as my receiver is attached to the robot.I made a vi which can extract the exact coordinates using my CRICKET sensor data.How to move a robot and simultaneously display its coordinates.In turn moving the robot usin roaming Vi as well as same time my VI display its coordinate.

    Hi,
    Is this an NXT robot and are you deploying your code on the robot?  Are you running the robot from a VI on you PC using blue tooth, etc... ?
    If you are running both VI's in LabVIEW you can use parallel loops.  If they have to communicate with each other, then you have to decide which approach to use with parallel loop communication.  Like simple variables or more complex choices like queue, etc...
    Can you provide more information about your system and version of LabVIEW?

  • How to loop through xml records and repeatedly display

    I have 1 table in my rtf and the table typically reflects 1 row (grouping) from my xml data, however there are some instances where i need to take 1 row from my xml data and display the table multiple times.
    i.e.
    xmldata:
    item TOTAL_QTY CONTAINER_QTY
    x 500 250
    I need to take that row and display the table in my rtf two times. I tried to encapsulate my table in a <?for-each:xdoxslt:foreach_number($_XDOCTX,0,TOTAL_QTY,CONTAINER_QTY)?> loop looping/re-displaying the table until a reach TOTAL_QTY, but once I'm in this loop it's like i dont have access to the actual xml data fields. How can I achieve this effect?

  • How can I see the size and colour of text in DW Cs5?

    Hi forum, how do you see the size and colour of a piece of text in Dreamweaver Cs5, I have some text in a dreamweaver file which is a size I like and a colour I like and I want to make a CSS rule with these characteristics. How can you see what size and colour a piece of text is?
    Many thanks for any help
    Gareth

    <td height="89" colspan="5" valign="top"><p><font color="#FF0066" size="-1" face="Arial, Helvetica, sans-serif">what is the text size, colour and boldness of this piece of text.</font></p></td>
    Above code is deprecated.  CS5 will not pick up these styles in the CSS styles panel.  Legacy sites are not simple to work with.  They need to be converted to  modern standards.  You do this by stripping the HTML styles from markup  and re-writing styles to CSS.
    <p>This is a normal paragraph</p>
    Put your CSS styles between your document's <head> and </head> tags:
    <style type="text/css">
    p {
    color: #FF0066;
    font-size: small;
    font-family: Arial, Helvetica, sans-serif;
    </style>
    Or, create an external stylesheet to which your HTML documents are linked like this:

  • How are listbox and radiobutton items working in oracle forms?!?

    Hi all.
    I need some help over may be a standard case in every real project.
    Imagine i have a db table PERSONS -> PERSONID, NAME, TOWNID, MATRIALSTATUSID
    and table TOWNS -> TOWNID, TOWNNAME
    and table MATRIALSTATUS -> MATRIALSTATUSID, NAME
    And i have a standard oracle form with text item person name, listbox item with many towns (from TOWNS table) and the town of the concrete person is selected when the form is inited, after that we can change it by selecting other town and saving it to db.
    The same is with matrial status but lets make it as radio group with 3 buttons married, not merried, divorced.
    So my questions is how to populate the listbox(radiogroup) for 1 person by selecting data from other preferenced tables. And most important how this data is populated in the list box for example i.e. every town name is indexed in some way or what. I am a java developer and for example in java the control listbox item has two attributes the name(string) that is displayed in the listbox and a index binded for that name, and i work with indexes and show strings. I read about LOV but couldn't understand how to "index" the populated values. Is it possible.
    And please can you give me some example of how to load (populate + set current town), change and (if it is possible) "index". The same case appears to be valid with radio buttons and check boxes.
    You could give me some tutorials too, i cant find simple and focused on the problem examples.
    Thank you.
    Best Regards.

    Hi,
    well here is what i done for now.
    First I created recordGroup with query SELECT GENDER, GENDERID FROM GENDERS (I want to select all genders and place them in listbox)
    After that i created Listbox and on triger when-new-form i placed this code:
    DECLARE
    it ITEM:=FIND_ITEM('PERSONS_DETAILS.GENDER');
    BEGIN
    CLEAR_LIST(it);
    POPULATE_LIST(it, 'RG_LIST');
    DEFAULT_VALUE(NULL, 'GLOBAL.PERSONID');
    IF :GLOBAL.PERSONID IS NOT NULL THEN
    SET_BLOCK_PROPERTY('PERSONS_DETAILS', ONETIME_WHERE, 'PERSONID=' || :GLOBAL.PERSONID);
    GO_BLOCK('PERSONS_DETAILS');
    EXECUTE_QUERY;
    :GLOBAL.PERSONID:=NULL;
    END IF;
    END;
    Imagine i have a main form PERSONS that displays general information about many persons (the data is retrieved from PERSONS db table). The form PERSONS displays PERSONID, PERSON FIRSTNAME and PERSON LASTNAME. When a user double click on some row from the PERSONS FORM( i have tabular datablock that displays the person data) other form 'PERSONS_DETAILS' must be displayed with detailed information about the selected person. The data about the selected person is loaded well but i want gender to be listbox and the user can change it if he wants. So i have TABLE GENDERS 1:N with PERSONS and the table has GENDERID AND GENDER. When the user double clicks on single person i must populate the list with all possible genders from the GENDERS table and set the gender of the selected person. How to do that?
    P.S.: The example with gender is not very good because it could be only male female, but don't worry about it. You may think about gender list as townlist :)
    It finds me the GENDER LIST and populates it. After that i take the personId (that is global variable and comes from previous form) and displays all the data for the person with id personid.
    When i compile the form it gives me :
    FRM-30351: No list elements defined for list item.
    List GENDER

    Good gracious.  It sounds like you were able to rotate the canvas a more or less exact multiple of 90° or you'd have spotted that it was skewed.  I just tried it using the r shortcut, and while it is doable, it is not particularly easy to rotate the canvas to a point where it could fool you.  What does surprise me, is that while the Options bar shows the degree of rotation while the r key is depressed, I could see nothing on the UI to tell me that the canvas was rotated.  That's something that you might want to start a thread on the Photoshop Feedback page.

    Anyway, Escape is the usual way to cancel rotate canvas.

  • How to make Multiple column listbox in CS4 using tree view

    Hi ,
    I am a beginer in Indesign Cs4 plug-in creation.In one scenario i want to create multiple column listbox,i tried with one cloumn using tree view and that is working fine.so suggest how to create multiple column listbox using tree view.
    thanks
    Arun

    InDesign does not have a native multi-column widget. You have three options:
    1) Use the treeview widget and align your widgets in the tree node to create the illusion of columns (stroke panel is an example - the Links panel in CS4 is a better example)
    2) Go the way of the CellPanel SDK example and tweek it to work like a listbox
    3) Create the User Interface in Flex

  • How do I script a listbox so multiple selections can be recognized?

    I have a pdf project that lets the user make selections from a listbox, and then those selections determine which fields on the page are shown or hidden. I've made sure the listbox allows for multiple selections but I can't get the scripting to recognize and show multiple fields. So far it only works when one item is selected. How do I make it so when the user selects multiple entries that it will actually cause multiple fields to show?
    I've included file to show what I've gotten done so far.

    Sorry, realized my other posts question wasn't phrased very well and I figured you thought my question had been answered. So I posted it again with a better explanation of what I needed.
    Thanks for your help.

  • How to transfer Painter 12 with my custom brushes from old iMac to a new iMac both running Mavericks

    Hi,
    I just purchased a new iMac. Have Painter 12 on my older iMac and want to be able to transfer Painter 12, with my custom brushes to my new iMac. Tried Airdrop but got a message that it was damaged and that I should trash it. Does any know how to get  Painter 12 with all my custom brushes to my new machine? Both are running Mavericks.
    Thank you,
    Jim

    etresoft,
    Thank you for your response. I did try to use Migration Assistant and I got as far as the two machines trying to communicate with each other. So I guess the answer to your question would be I tried, I failed and it worked until a certain point. I understand that there are other ways to connect the machines, I would have to see if I have the proper cables to do so. Airdrop did get data to my new machine and that tells me that they do see each other on the network. I do not know why they did not see each other via Migration Assistant. I assume that I could go to Corel's site and download Painter 12 to my new machine, ( my new machine does not have a disk drive ), but I will not have my custom brushes etc. and would have to totally make them up in the fresh install version and I am trying to avoid that.
    You are probably correct in saying that Painter 12 probably needs a full reinstallation to work properly. Am I to assume that Migration Assistant will do a full reinstallation, including my custom brushes? I guess I am a little confused here.
