Abstract

System and method for performing program-related operations over a network via a web browser. A network connection is established between a server computer and a client computer over a network. A universal resource identifier (URI) is sent from the client computer to the server computer over the network, where the URI indicates a program, e.g., a graphical program (GP), or at least a portion of a graphical program interactive development environment (GPIDE), e.g., a graphical program editor, an execution engine, a static or dynamic analyzer, and/or compiler. The at least a portion of the GPIDE is received from the server computer over the network in response to the URI, and executed in a web browser of the client computer to perform some specified functionality with respect to the GP.

send an indication of the assessed charge to a user of the GDFP, or a representative of the user.

15. The memory medium of claim 1, wherein the program instructions are further executable to:

bill an account associated with the user in accordance with the assessed charge;

or

send a bill for the assessed charge to the user of the GDFP, or a representative of the user.

16. The memory medium of claim 1, wherein the program instructions are further executable to:
