We have been unsuccessful in setting the start and finish dates for the timeline. We have followed the example without success. There may be a compatibility issue. We are using Visio Premium 2010, 32-bit. Our development environment is VS 2010 with the 3.5 framework. The version of Aspose is 5.6. In the zip file is a stencil, Modernization.vss, which the project is currently looking for at C:\Temp\.
<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
The program runs without error and generated a pdf, but the dates on the timeline do not change from the stencil.
