FileMaker Pro 12 to 17


If you specify a zero as maxval, an indefinite progress bar is shown (barber pole).

In some cases the time to perform lengthy scripts might increase, as FileMaker updates the screen after the ProgressBar step. A freeze screen step does not always help.

IMPORTANT Use only in a script. Do not use this function in a calculated field definition, because when FileMaker calculates the fields this will result into a repeated dialog for EACH record. Also note that functions that use the clipboard, like pasting in a container field, will not work, as they try to paste in the progress bar window.

See also the Dial_SetPreference function to change the time of automatic removal of a progress dialog.

You can also suppress the title in all ProgressBar dialogs by adding this to your (startup) script:

Dial_SetPreference ( "-TitlesInProgressBarDialogs" ; "off" )

This will set the Progress bar title to blank for all subsequent calls until FileMaker is restarted.


Use this function to indicate to a user that a script is doing a lengthy operation and provide feedback on how long this operation will last.

For a detailed description see the section “Using the Dial_ProgressBar function” in the user guide.
