In this tutorial we add a routine that actually changes the project. When changing the project, it is required that an “UndoBlock” be used or an error will occur in the Custom Command. By using the UndoBlock, we not only eliminate the error but we can also create custom names that will appear in the “Undo” list in VEGAS.
The UndoBlock is used as follows:
using (UndoBlock undo = new UndoBlock("Undo List Name"))
{
//Code for this task
}
