How to programmatically change color of arc in cwknob

trying to change color of arc in cwknob control conditonally

I'm not entirely sure what part of the control you are referring to by "arc". Can you elaborate?
If you mean the (by default) black line that the pointer points to when you choose a meter style and to which the major and minor ticks are connected, you can change its color with the following code:
CWKnob1.Axis.Ticks.MajorTickColor = vbYellow
If you looked for and didn't find the property you need, I suggest you check out the properties of the Axis subobject of the knob. People frequently overlook this important subobject of the knob and slide.
In general, if you are able to configure a property on any property page except the Advanced property page, you should be able to configure it programmatically.
If my suggestions above don't get the job done
for you, you could take screen capture of the control, drop it in Paint, circle the portion of the control you want to configure, and attach it to a response to this post.

  • How do you change color of screen in dreamweaver?

    Hello how do you change color of screen in dreamweaver website?

    Do you mean the background-color of the actual site, or are you talking about the color of the DW interface?
    In DWCC, you can go to Modify > Page Properties to change things like the background-color, text color and more for the actual web page.
    You can also change it in the CSS Designer panel by creating a body selector in the css, then make the change in the CSS Designer's properties sub window.

  • How do I change color in a selection, not globally?

    Hi guys,
    My question is how do I change color in a selection and not globally? My company uses Freehand currently and there is an option to find and replace color in a selection instead of the entire document. I need to figure out how to do this in Illustrator as we will be switching over shortly.
    Thanks,

  • How to programmatically change the cell color of an ADF table ?

    Hi all,
    I have an ADF table with some fields on it. Depending on the value of a field named, say, "F1", I would like to change its background color.
    So far I can change the field color with this EL expression inside the InlineStyle table column property:
    font-size:medium; background-color:#{viewScope.myBean.setColor};
    where setColor is a bean function, in where I access the field "F1" via binding, parse its value, and return the right value - so far, so good.
    The bad thing is, the InlineStyle affects that field in all the rows of the table, while I would like to change only the field in the rows, which have that specific value in it.
    So for example having the rows:
    F1
    abc#1 ----> currently selected row
    cde#2
    efg#3
    I want to change the background color to all the F1 fields which have a "1" after the '#' and let the other "F1" row cells background color stay unchanged.
    But as you can imagine, the InlineStyle affect the "F1" background color in all the rows (assuming that the first row of the table is selected).
    So the question: how to access a single cell of a row in an ADF table, and programmatically change its background color ?
    So far I can iterate through the ADF table with:
    BindingContext bindingctx = BindingContext.getCurrent();
    BindingContainer bindings = bindingctx.getCurrentBindingsEntry();
    DCBindingContainer bindingsImpl = (DCBindingContainer) bindings;
    DCIteratorBinding dciter = bindingsImpl.findIteratorBinding("aTableIterator");//access the iterator by its ID value in the PageDef file
    RowSetIterator rsi = dciter.getRowSetIterator();
    System.out.println("rsi getrowcount = " rsi.getRowCount());+
    Row row = null;
    +if (rsi.getRowCount() > 0) {+
    row = rsi.getCurrentRow();
    System.out.println("row attr = " Arrays.toString(row.getAttributeNames()));+
    System.out.println("class : " row.getAttribute("F1").getClass().toString());+
    +}+
    +while (rsi.hasNext()) {+
    row = rsi.next();
    System.out.println("row attr = " Arrays.toString(row.getAttributeNames()));+
    +}+
    Regards,
    Sergio.

    Hi,
    I mean a specific cell within a row.
    Here are two pictures that show an ADF table with two rows and some fields on it:
    https://skydrive.live.com/?cid=7D3084D8BF755808&id=7D3084D8BF755808!107&sc=documents#cid=7D3084D8BF755808&id=7D3084D8BF755808!107&sc=documents
    bild_A is what I have, bild_B is what I would like. Note that:
    in bild_A the first row contain a yellow background color for the field F4 and an orange background color for the field F5. This is correct, because F4 has an "1" at the end of its string value, and F5 has a "3" at the end. So far so good.
    But the second row (again, bild_A) has also the fields F4 with yellow background color, and the field F5 with orange background color, even if the value in both fields is 0.
    What is should be, is shown in bild_B.
    The problem is that the solution provided affects all the cells of the column, while I need to change the background color of a single cell, and leave the other unchanged (see bild_B).
    I hope that clarify a bit :)

  • How do you change color of an event in a calendar in ical

    how do I change the color of an EVENTt in ical

    boivinr wrote:
    PLEASE APPLE ADD COLOR TAGGING TO EVENTS!!!
    Um, color tagging events has always been a feature of iCal. Go into iCal. In the upper left-hand corner it says "Calendars." Go under "File" and create a new Calendar--iCal will give it a color, but you can change that. If you do this in iCloud, you simply pick "edit" and click on the color, and you've a huge range of choices as to what color you want it to be.
    So, now you've got calendars--the family events calendar (named "Family") the "Days Off" calendar and the "Appointments" calendar...each with their own color. You can see them all when you click on "calendars" there on the left-hand side. And, in your case, can create calendars for each person at your work to know when they'll be on or off work. "John's calendar" and "Susan's calendar."
    You create an event, and among the choices you have (date, time, alert, notes) is one that says: "Calendar." It will show the default calendar with it's color, but offer you up and down arrows to pick a different calendar (you can change the default calendar, by the way, under preferences). You use those arrows and pick "John" calendar and the "event" of John being on-shift from 10pm-10am on December 12th appears on the calendar in orange. Create an event and give it the "Susan Off" calendar and her time off will appear in green. Give several events the "appointment" calendar and they'll all be blue (or whatever colors you've picked for these things).
    Yes?
    Now whether you can sync your iCal to Google and match up the colors is a whole other story. But you can--and have for as long as I can remember---color code your iCal events.

  • How Do I change color randomly of a MovieClip in a Timer event?

    I have created a MovieClip named "Target" and called it from actionscript. Inside this movie clip I have created an 'action' layer and written the code in it:
    import fl.motion.Animator;
    import fl.motion.MotionEvent;
    var this_xml:XML = <Motion duration="30" xmlns="fl.motion.*" xmlns:geom="flash.geom.*" xmlns:filters="flash.filters.*">
        <source>
            <Source frameRate="12" x="202" y="169.15" scaleX="1" scaleY="1" rotation="0" elementType="movie clip" symbolName="Target">
                <dimensions>
                    <geom:Rectangle left="-32.05" top="-30.85" width="64.05" height="61.7"/>
                </dimensions>
                <transformationPoint>
                    <geom:Point x="0.5003903200624512" y="0.5"/>
                </transformationPoint>
            </Source>
        </source>
        <Keyframe index="0" tweenSnap="true" tweenSync="true">
            <tweens>
                <SimpleEase ease="0"/>
            </tweens>
        </Keyframe>
        <Keyframe index="29" scaleX="2.096" scaleY="2.096"/>
    </Motion>;
    var this_animator:Animator = new Animator(this_xml, this);
    this_animator.play();
    this_animator.addEventListener(MotionEvent.MOTION_END, removeTarget);
    function removeTarget(event:MotionEvent):void
        this.parent.removeChild(this);
    In the main timeline I also have created another 'action' layer and written the code like this:
    var timer:Timer;
    var targetCount:uint;
    var container:MovieClip;
    function initGame():void
        container = new MovieClip();
        addChild(container);
        targetCount = 10;
        timer = new Timer(1000, targetCount);
        timer.addEventListener(TimerEvent.TIMER, generateTarget);
        timer.start();
    function generateTarget(event:TimerEvent):void
        var target:MovieClip = new Target();
         target.x = Math.random() * stage.stageWidth;
        target.y = Math.random() * stage.stageHeight;
        container.addChild(target);
    initGame();
    Now I can get 10 animating circles in different places of the stage after every second. And every circles will leave the stage after completing the animation. Though I have given 'pink' color in that circle, that's why its generating with 'pink' color always. How do I change the color of each circle while it will generate?
    Regards
    Dipesh Pal.

    I have tried in this way......
    function generateTarget(event:TimerEvent):void
        var target:MovieClip = new Target();
        var colorT:ColorTransform = new ColorTransform();
        colorT.redOffset = Math.round(Math.random() * 510) - 255;
        colorT.greenOffset = Math.round(Math.random() * 510) - 255;
        target.transform.colorTransform = colorT;
        target.x = Math.random() * stage.stageWidth;
        target.y = Math.random() * stage.stageHeight;
        container.addChild(target);
    but its not working......
    infact i have used function 'circleColor' which holds this random color transform.... and call that function from 'generateTarget' function also....but it doesnt work too...
    then how do I change the color of every circle which is randomly generating in the stage....?

  • How do I change color on visited sites without causing websites to not view properly?

    I go to Content/Colors, change color of visited sites, uncheck "allow pages to choose own colors instead of my selections above".
    The visited sites change colors, but the websites that I go to do not view properly. They do not have names or headings or shopping carts or search boxes and are very hard to maneuver through.

    You can use code in userContent.css or use the Stylish extension to override the page colors.
    I use code like this:
    <pre><nowiki>a:visited {color:#e08!important;background-color:#eee}
    a:visited * {color:#e08!important;outline:1px dotted red!important;outline-offset:-1px}
