In addition to the Filter Bar, the Messages view can be filtered further with column filters. Column filters affect the display and the contents of saved buffer files, just like the Filter Bar does. They are also turned on and off using the Filter button at the top of the Filter Bar.
Column filters are located in the row of blank fields just below the column headers as seen in Figure 1. The black/gray Filter text at the far left of that row indicates the Filter button status.
Column filters provide a fast and efficient way to sort through hundreds of messages without setting up a custom filter. Each column has its own filter and multiple columns can be filtered at the same time. Vehicle Spy supports two methods of column filtering.
Pulldown list column filter selections are automatically created by Vehicle Spy as a buffer is collected. To access the list, click three times in the blank field below the column header you want to filter. Then click the arrow to see the pulldown list filter selections like that shown in the Description column in Figure 1. The list contains every unique data item in that column. Click on one of the filters and press Enter*. The filter name fills the space under the column heading and only messages matching that filter are shown.
Imagine for a moment working with hundreds of messages. The specific message desired has an arbitration ID with a 6 in it, but the actual number has been forgotten. Simply type 6 in the blank field beneath the Arb ID column heading and press Enter*. Only messages with an Arb ID that includes a 6 are visible such as 640, 126, and 260.
For another example, imagine knowing a desired arbitration ID begins with a 1. Simply enter in 1?? and Vehicle Spy shows all three digit Arb IDs beginning with the number 1 like 110 and 123.
To include more than one message in a filter, separate them using a comma like ?2?, 110, ?33. These column filters work on other columns as well. When working with a database and all messages and signals are defined, enter eng or odo in the blank field below the Description header. Only messages and signals with those letters in their descriptions, those pertaining to engine and odometer, will remain.
*To apply a column filter while offline, after pressing Enter, make sure to click in the main display area to see it take effect.
To delete a column filter, click and highlight it, then press the Delete key and Enter key to confirm.
To disable all column filters without changing them, use the Filter button above the Filter Bar. The Filter text and column filter names will fade to gray when they are disabled.
