How to Add Index Functoids to a Map

  • Article

The Index functoid enables you to select information from a specific record in a series of looping records. Each Index functoid selects information from a single field.

For conceptual information about the Index functoid, see Index Functoid.

To add the Index functoid to a map and configure it

  1. With the Visual Studio Toolbox active, click the Advanced Functoids tab to select that category of functoids.

    The list of advanced functoids in the chosen category appears.

  2. Drag the Index functoid (Small image showing the icon for the Index functoid.) from the Toolbox to the appropriate location on a grid page.

    Note

    The functoid will be placed on the displayed grid page. If you want to put the functoid onto a different grid page, you need to display the other grid page first.

    Note

    If you are constructing a map using more than one functoid together, you need to consider their relative left-to-right placement. Functoids are executed from left to right. The output of a functoid can only be input to another functoid that is farther to the right.

  3. To establish the field input parameter for the Index functoid, create an input link by dragging a field within a looping record from the source schema to the Index functoid, or dragging the Index functoid to a field within the looping record in the source schema.

  4. To establish at least one index input parameter for the Index functoid, perform the following steps:

    1. With the Index functoid selected, click the ellipsis (...) button associated with the Input Parameters property in the Properties window.

    2. In the Configure Index Functoid dialog box, click the Adding constant input parameters to a functoid button.

    3. In the edit box, type the index input parameter as a numeric value. Repeat as necessary if additional index values are required, and then click OK.

  5. To use the output parameter from the Index functoid, create an output link by dragging the Index functoid to a field in the destination schema, or by dragging a field in the destination schema to the Index functoid.

    Note

    As with other functoids, the output of the Index functoid can be used as input to another functoid.
