VISTA Scheduling GUI Home Page

Welcome to the VISTA Scheduling GUI homepage. I am Sam Habiel; I am the current maintainer for the Scheduling GUI. I can be reached at sam dot habiel at gmail dot com. The original package was written for Indian Health Service by Horace Whitt, and I ported it to VISTA and made a lot of enhancements.

What is the Scheduling GUI?

Historically, VISTA has always used the PIMS Scheduling module on the VT-100 emulated terminal. The Scheduling GUI is intended to be a replacement and complement for PIMS Scheduling. You can run the Scheduling GUI without any interaction with PIMS; or you can have it interacting with PIMS so that appointments will have various cascading effects on other packages using the PIMS triggered protocols and PIMS APIs. Most people use it with PIMS so that it can integrate well with CPRS.

I want it I want it I want it!

You can follow the instructions here to install it: source:Scheduling/tag/1.5/README.txt​

What is the Scheduling GUI written in?

The client is in C# using the .Net 4.0 libraries on MS Windows. The Windowing library used is WinForms 2.0. The database side uses Plain Jane remote procedures over a custom broker developed by Indian Health Service called BMX that provides ADO.net support to Fileman. Currently, most remote procedures are very heavy Mumps.

Show me some code!

This is the C# code that inits the Scheduling GUI.
