Dialog Builder refers to the Origin C support to use Microsoft Visual C++ generated resource DLL for building floating tools, dialog boxes, and wizards in Origin. All resource elements, including Windows common controls and Origin's worksheet and graph controls can be accessed and controlled from Origin C. This capability used to require a Dialog Builder license, but since Origin 8.5, this restriction has been removed and all Origin installations include this support.
This guide contains a tutorial that shows how to use Microsoft Visual C++ to create a resource-only DLL containing a dialog and then how to use Origin C to display the dialog. Additional sections describe in more detail how to create a resource-only DLL and access it's resources from Origin C.
