Bill,
In your loop you need to set the thumbPosition of the scrollbar to a value and it will move. Here's an example for a progress bar based on the total number of cards:
Ken's handler should do the job; but if you want something a little more generic:
put the number of cards into recordCount
set the thumbPosition of scrollBar "Progress Scrollbar" to 0
set the endvalue of scrollBar "Progress Scrollbar" to recordCount
show scrollBar "Progress Scrollbar"
put 0 into recordsProcessed
put round(recordCount/(the width of scrollBar "Progress Scrollbar")) into progressInterval -- the minimum change in thumbPosition value to move the bar 1 pixel
put max(1,progressInterval) into progressInterval -- adjust for intervals < 1
repeat with x=1 to recordCount
set cursor to busy
[card processing logic here]
add 1 to recordsProcessed
if (recordsProcessed mod progressInterval)=0 then set the thumbPosition of scrollBar "Progress Scrollbar" to recordsProcessed
end repeat
set the thumbPosition of scrollBar "Progress Scrollbar" to recordCount -- yes, recordCount: make sure progress shows 100% complete
This logic calculates the minimum value change required to move the thumbPosition 1 pixel based on the length of the progress bar in pixels and the endValue. It only updates the progress bar when the aggregate change in thumbPosition value is large enough to move the thumbPosition 1 pixel. (Eg: Assuming a 100 pixel progress bar, the thumbPosition would be updated every card in a 100-card stack, every 10 cards in a 1,000-card stack, every 100 cards in a 10,000-card stack.) Note the interval adjusts automatically when the length of the progress bar is changed.
