How can you fill ListBox with channel group name dynamically?

I built a GUI in the 'View' pane that acts as a large table of contents. At the top of the GUI, there is a list box I want to dynamically fill with Group channel names loaded in my data portal (internal data). I can't generate the necessary code to do this. Currently, I use a ListBox control. Can I use an EnumListBox instead?

The purpose of the list box should allow fast loading data which must be analysed in several sheets (also in the part of 'View') for comparison side by side rather than drag and drop data into each individual record.

Any help would be appreciated,

Thank you

~ Nathan

Attached is a screenshot of the GUI I hope it helps.

Hey Nathan--

Have we met yet?  Don't think that I will remember to see you post on the forums of tiara so far (or remember you I meet someone named Nathan in person recently).  Welcome to the forums of tiara!

There are a few things that you need to change about your code snippet-

  1. The reason why you get the error "object required: ' [string: 'filename']' is because the Set command expects that the right side of an expression returns an object (you define your variable to)."  In your case, you return a string (the name of a group), not an object.  Simply remove the Set command.

  2. The ListBox.Items.Add () method requires two parameters - the first is the text of the item to insert in the list, and the second is a value to assign to this point (you can do single).

As a result, to more directly match your code snippet to the labour code, follow these steps:

Dim listNum, names
We = 1 to GroupCount
Name = GroupName (listNum)
Call selectData.Items.Add (names, we)
NEXT

Note that you can also use object programming oriented with the data object that represents the data portal, it is easier for you to avoid remembering variables such as GroupCount and GroupName DIAdem (that's me):

Dim listNum

We = 1 to Data.Root.ChannelGroups.Count

  Dial selectData.Items.Add (Data.Root.ChannelGroups (listNum). Name, we)

NEXT

Your project is looking great - let us know how we can continue to help and keep us updated!

  • How can you fill a hollow fonts with color in Indesign

    Hello

    someone knows something about how to fill it with the color of the inside of a police dig?

    The policy in question is ROSEWOOD (rosewood - download free fonts)

    Here is a picture of the police.

    Rosewood.gif

    The white parts are actually empty hollow parts of the police...

    Any suggestion?

    OK, I found a solution... I found a version of the same font, called to FILL.  Using two layers, I was able to fill the police with police filling in the layer under.

    That being said, I still wonder if there is a way to fill the hollow fonts with colours, where a policy of filling would be unavailable...

    All suggestions welcome.

    Make sure that the software firewall, AV, or other security components allow free local traffic on all network computers. If you use the 3rd group of security, firewall native Vista/XP must be disabled, and the active firewall has adjusted to your network numbers IP on what is sometimes called the Zone of confidence (see part 3 firewall instructions

    General example, http://www.ezlan.net/faq.html#trusted
    Please Note that some 3rd party software firewall/AV/security costumes continue to block aspects of the Local traffic even it they are off (off).     If possible, configure the firewall correctly or completely uninstall to allow a clean flow of local network traffic.

    If you end up with the 3rd party software uninstalled or disabled, make sure that Windows native firewall is active .

    Most OEM computers have a partition on the hard drive, that allows to give it bought as provided.  Usually, you activate this feature by pressing a key or combination of keys when the first splash screen appears at startup.  Look quickly at the first screen that appears, and you could see the key that you press.  Otherwise, go to your computer manufacturer's website and download the manual for your computer.  Instructions must be there.

  • How can you change a text in an image?

    How can you change a text in an image?

    Hi Jasper,.

    It depends on how the text has been staged, and what has been done with the image after that.

    A quick test - what happens when you zoom in on, or enlarge the image?

    If the text retains its edges when amplified, then it can probably be edited separately from the image. If the text begins to show pixelation on the edges (like the picture), then there is no text to change, what looks like adding text is actually part of the image and can only be changed in the same way that you can change anywhere in the image.

    Here is an example:

    The photo is a photo (jpeg format), inserted in a Pages document created with the essay template. White text in the upper left corner of the photo is placed in a text box. To put the photo on this page (and the text on and around it) has been converted to a PNG file. When it is enlarged on this screen, the text finally a pixelated image...

    .. .the easily noticed in the thin relates diagonal 'o'.

    In Pages, however, the text and the picture are separated, and the text is a vector image - mathematically trained and scalable.

    The text here is contained in a text box and the text box was grouped with the photo. To change the text (in Pages), I need to:

    • Click on the text.
      Handles will appear in the corners of the selection.
      That click you select either the entire image OR just simply the text box.
      • IF the handles are blue x characters, the selection is locked
        Go organize (menu) > Unlock
        Sectionals unlocked handles are small white squares.
    • IF the selection includes the entire image
      • Go to the menu, rearrange and choose ungroup
        If the choice to separate is not available, the text may be part of the image and uneditable as text.
        Try to click twice (separated from the clicks, not double click).
        If the insertion point (|) is now in the text, the text is editable as text.
        Change the text.
    • IF the selection looks like a text box and does not the whole image
      • Click on the text to place the insertion point (]) in the text
        Change the text.

    Image showing the insertion point in the text in a text box on the image:
