Question

Is it better to show ProgressBar UserForms in VBA as modal or modeless? What are the best practices for developing progress indicators in VBA?

Modeless UserForms req

Answer 1

Actually you have following properties, resulting in pros/cons depending on your need:

Type      | Impact on UI | Impact on caller execution
----------|--------------|-----------------------------
Modal     | Blocked      | Blocked until Form is closed
Modeless  | Not blocked  | Continues

If you want to block the UI AND let the caller continue, then you need to open the Form in modal mode with Application.OnTime.
