Hi,
Currently I am building a .dbf of filenames from a Windows folder and its subfolders.

I wish to have a progress bar to display "while" the .dbf is being populated.

I have inserted a progress bar from the testmex.prg sample into my code.

Problem is the progress bar dialog is only displayed upon completion, not while the .dbf is building.

I am unsure how to accomplish the task.

At the risk of leaving something out , I include the entire function.

Any help appreciated,
Bruce S.

Bruce, you can start with this example the "syswait()" is only there to slower the operation.

Euclides,

Thank you, I will pursue
