This version or that version?

It might be required to create an instance of a specific version of a process. Some reasons:

0. When exporting a new version of a process, the K2 server makes it the default version automatically. This is a bit of a pain as new instances of the new exported process will be automatically created by clients that don't spesify a spesific version.

1. Export process that's passed QA in development to production and run final pre-production testing before making the process live. In this scenario your user interface will always specify the version of the process when creating an instance.

2. Sometimes changes to a process require changes to the user and/or system interfaces. In this scenario the user interface can create a process on a specific version but should also render itself correctly for a specific version of the process (more about that in the next blog).
Using the K2ROM.dll library one can specify what version of the process to create using the overloaded .CreateProcessinstance method.

SourceCode.K2ROM.Connection con = new SourceCode.K2ROM.Connection();
con.Open("127.0.0.1");

SourceCode.K2ROM.ProcessInstance pi;
pi = con.CreateProcessInstance(@"Project\Process", 2);

This will create an instance of the Process process using version 2.
