The Microsoft Visual Programming Language (VPL) is a new application development environment designed specifically to work with DSS Services. Programs are defined graphically in data flow diagrams rather than the typical sequence of commands and instructions found in other programming languages. VPL is useful for beginning programmers because they can quickly specify their intent but it is also well suited to help with prototyping for more experienced programmers because it can generate C# code.
This chapter covers:
This chapter contains nine basic VPL examples, starting with the obligatory "Hello World". The links below show screenshots of the VPL diagrams.
The last example, Lists, is fairly complex and involves several custom activities. Only the first diagram is shown via the link above.
Note that to use VPL you should have at least 1GB of memory in your PC.
