Abstract

A computer program for validating and controlling processing of input data from electronic forms such as Hypertext Markup Language (HTML) forms. Data including the input data is received from a form submitted to a server, wherein the server includes a registry. The program uses information stored in the registry to determine whether the input data from the form is valid.

Claims

1. A computer-implemented method for validating input data, the method comprising:

receiving data including input data from a form submitted from a first computer system to a second computer system, the form being stored on the second computer system and electively accessed via the first computer system, the second computer system including a registry; and

determining whether the input data is valid using information stored in the registry.

2. The computer-implemented method of claim 1 further including determining whether the data from the electronic form includes a first registry key identifier and wherein determining whether the input data is valid is performed only if the data includes the first registry key identifier.

3. The computer-implemented method of claim 1 wherein the information stored in the registry is stored in at least one configuration key associated with a first registry key identified in the data.

4. The computer-implemented method of claim 1 wherein the form includes fields for entering input data and the data received from the form includes input data corresponding to the fields, wherein determining whether the input data is valid includes:

comparing input data corresponding to each field with a corresponding entry in the registry,

if a first item of input data corresponding to a particular field is invalid, indicating an error in an error log, and

repeating comparing and indicating until input data corresponding to all fields of the form have been evaluated.

5. The computer-implemented method of claim 4 further including:

if an error has not been indicated in the error log after input data corresponding to all fields of the form have been evaluated, invoking a data processing program to process the input data, and

if at least one error has been indicated in the error log after input data corresponding to all fields of the form have been evaluated, sending an error message to the first computer system.

6. The computer-implemented method of claim 5 wherein the data processing program to be invoked is specified in the registry.

7. The computer-implemented method as set forth in claim 4 wherein indicating an error in an error log includes dynamically building an error message corresponding to the particular field using the information stored in the registry.

8. The computer-implemented method of claim 1 wherein the electronic form is a Hypertext Markup Language (HTML) form accessed by a client over the Internet.

9. An apparatus comprising:

a registry in a first computer system to store a registry key corresponding to an electronic form to be stored in the first computer system; and

a form data validation and processing control module in the first computer system to determine whether input data entered into the electronic form via a second computer system is valid using information stored in the registry, wherein the form is electively accessed by the second computer system.

10. The apparatus of claim 9 wherein the form data validation and processing control module only determines whether the input:

data is valid using information stored in the registry if data from the electronic form including the input data identifies the registry key.

11. The apparatus of claim 9 wherein the information stored in the registry that is used to determine whether the input data is valid is stored in one or more configuration subkeys corresponding to the registry key.

12. The apparatus of claim 9 wherein the registry specifies one or more data processing programs and wherein the form data validation and processing control module invokes one of the data processing programs if the input data is determined to be valid.

13. The apparatus of claim 9 wherein the electronic form includes one or more input fields and the input data includes one or more data items corresponding to the one or more input fields, and wherein the form data validation and processing control module is further to dynamically produce an error message to indicate each of the fields for which the corresponding data item is determined to be invalid using the information stored in the registry.

14. The apparatus of claim 13 wherein the registry includes at least one configuration subkey to indicate a data processing program to be invoked if the input data is determined to be valid, and to store the information used to determine whether the input data is valid, the information including validation information corresponding to each field.

15. The apparatus of claim 9 further including a wizard coupled to the registry, the wizard to respond to input information to configure the registry and store the information used to determine whether the input data is valid.

16. A computer system comprising:

a processor to process information;

a registry; and

a form data validation and processing program stored in a memory coupled to the processor, the form data validation and processing program to be executed by the processor to determine whether input data received from an electronic form from a remote computer system is valid using information stored in the registry, wherein the electronic form is stored in the computer system and electively accessed by the remote computer system.

17. The computer system of claim 16 further including a network connection wherein data from the electronic form including the input data is received from a client system through the network connection.

18. The computer system of claim 16 wherein the registry includes a first registry key corresponding to the electronic form and wherein the form data validation and processing control program is further to determine whether data from the electronic form including the input data identifies the first registry key.

19. The computer system of claim 16 wherein the form data validation and processing control program is further to dynamically build an error message using information stored in the registry if input data is invalid.

20. The computer system of claim 19 wherein the error message specifies each field of the electronic form for which input data is determined to be invalid.

21. The computer system of claim 16 further including a wizard coupled to the registry to control storage of the information in the registry used to determine whether the input data is valid.

22. The computer system of claim 16 wherein the registry is part of an operating system.

23. A machine readable medium having stored thereon data representing sequences of instructions, which, when executed by a first computer system, cause the first computer system to perform a process comprising:

providing a second computer system elective access to an electronic form; and

determining whether input data entered into the electronic form from the second computer system is valid using information stored in a registry on the first computer system.

24. The machine readable medium of claim 23 further causing the first computer system to perform the process comprising:

determining whether data from a particular electronic form can be validated by determining whether the data identifies a valid registry key in the registry.

25. The machine readable medium of claim 23 further causing the first computer system to perform the process comprising:

dynamically building an error message indicating each field of the electronic form for which input data was determined to be invalid using the information stored in the registry,

sending the dynamically built error message to a client from which the input data was received if input data was determined to be invalid, and

invoking a data processing program indicated in the registry if the input data was determined to be valid.
