Create Empty 2D Array
Activity allows to create an empty two-dimensional array.
Arrays are used to store multiple elements as a single variable. An array is the data structure that stores a fixed number of elements of the same data type. The type of data stored in the array has to be specified beforehand. You cannot change the size or type of an existing array after it has been created. The elements of an array are indexed, starting with index (0)(0) - the first rank denotes the number of row, and the second one defines number of column.
The following figure illustrates the two-dimensional array 3x4 divided into rows and columns.
Dragging the activity to flowchart opens an input window requiring you to select your array’s data type, followed by activity window itself. You can specify the size of the array (give the number of rows and columns) and give a name to the Array there (create a variable, type e.g. String[][] or Int32[][], it must match chosen Element Type).
Array elements can be accessed using an index - simply type array name followed by element's indices in brackets (arr2d(1)(2) addreses to the element of the array "hh" - illustration above).
| Name | Type | Category | Description |
|---|---|---|---|
| Alternative Scenario If Failed | Boolean | Misc | checkbox; default is "on" |
| Array | Literal | Output | name of the array |
| Columns | Int32 | Input | number of columns of the array |
| Display Name | Literal | Misc | changes display name of the activity |
| Element Type | Dropdown | Input | select element type from the dropdown list |
| Exclude from Transaction Check | Boolean | Misc | checkbox; default is "off" |
| Fullscreen | Boolean | Screenshot | checkbox; default is "off" |
| Result | Boolean | Output | returns a Boolean value. True if no error in activity, otherwise will return False |
| Result Code | Int32 | Output | Result Code will return 0 if there is no error in activity, otherwise in most cases will return 1. See the table of Extended Result Codes for more info |
| Rows | Int32 | Input | number of rows of the array |
| Screenshot Path | String | Screenshot | directory path to save location |
| Show Cursor | Boolean | Screenshot | checkbox; default is "off" |
