One of the most useful features introduced with the Windows 7 taskbar was the ability to display progress information directly on your form’s taskbar button.  OpenInsight 10 exposes this functionality via two new WINDOW properties:

• PROGRESSVALUE
• PROGRESSSTATE

PROGRESSVALUE Property

This is a simple @fm-delimited array composed of two fields that contain the current progress value (i.e. the proportion complete) and the maximum progress value (i.e. the value when completed).

Example:

PROGRESSVALUE of 50,100

Note that this property is set-only.

PROGRESSSTATE Property

This property specifies the appearance of the progress bar. It can be one of the following values:

• “0” – No progress Information
• “1” – Normal (green)
• “2” – Error (red)
• “3” – Paused (yellow)
• “4” – Indeterminate (this results in a marquee-style effect)

Example:

PROGRESSSTATE of 2

PROGRESSSTATE of 3

Note that this property is set-only.
