This section provides an example of using the "Invoke Code" activity to sum up amounts from a data table.

Drag and drop "Core" > "Data Table" > "Build Data Table" onto the workflow.

Click on "Data Table", then enter product names and their corresponding prices, as shown in the image below.
(You can enter any values as needed.)

Assign a DataTable-type variable (e.g., dtSample) to the "Data Table" property.

If needed, refer to "Creating Variables" for more details.

Drag and drop "Core" > "Invoke" > "Invoke Code" onto the workflow.

Click "Edit Arguments" in the Invoke Code activity.

Enter the following arguments:

• in_dtSample (Type: DataTable, Direction: Input, Value: dtSample)

• out_inSum (Type: Int32, Direction: Output, Value: inSum)

Click "Edit Code" in the Invoke Code activity and enter the following code in the editor:

vb

CopyEdit

Dim row As DataRow

out_inSum = 0

For Each row In in_dtSample.Rows

    out_inSum = CInt(row("Price").ToString) + out_inSum

Next row

Drag and drop "Core" > "Dialog" > "Message Box" onto the workflow.

Assign the inSum variable (of type Int32) to the "Text" property and append ".ToString" to convert it into a string.

Click "Home > Start" or press F5 to run the robot.

Verify that the total sum of the amounts entered in "Build Data Table" is displayed in the message box.
