Updates the progress bar and the message underneath it.
You should always call SoftadminApi.Progress_SetTitle before calling SoftadminApi.Progress_SetStep
, but once you've set a title the same title will be automatically used for all following steps.
You can either use indeterminate progress, in which case you omit the @-Steps parameters, or determinate progress, in which case 0 <= @CompletedSteps <= @TotalSteps.
Can be used with Execute, Delete and NewEdit. For Web Service Call, use the component's own columns instead.
