Application shutdown with UPS....

[daveu]

My application is written using LV6i. I am also using a UPS (that has it's own software for managing the shutdown of windows). In the event of a power failure, the UPS supplies battery back-up power to the computer for 3 minutes. After 3 minutes, the UPS software shuts windows down, along with my application. 

Right now, the shutdown sequence kills my application, and all unsaved and open files are lost.

Is there any way that I can be informed by windows that it's about to shutdown my application so that I may save data and close all files before windows closes my application?

Thanks in advance.

Hello,

Perhaps you can read a Windows dll to check whether or not the battery or the UPS is supplying power, or monitor or poll the UPS software for the state of the power supply.  In LabVIEW you would use the call library function node to call the dll function.  I am not familiar with using a UPS or corresponding software, so I can't speculate as to other options for "messaging" such information from a UPS to the OS or a programming environment like LabVIEW.
