Abstract

Managed and unmanaged code may operate in a document environment by enabling managed code to be called by unmanaged code. The managed code may make functions available to unmanaged code by creating a type library and loading the type library into a running object table using a filename identifier. The filename identifier may be used by the unmanaged code to locate the type library and thereby call managed code functions.

Claims

1. A method comprising:

defining an identifier for a first group of managed code;

defining a callable function within said first group of managed code;

defining a type library for said callable function;

adding said identifier to a second group of unmanaged code, said second group of unmanaged code adapted to;

search for said type library using said identifier;

finding said identifier in said running object table;

loading said type library from said running object table; and

calling said callable function.

2. The method of claim 1, said identifier comprising a filename.

3. The method of claim 1, said identifier comprising a GUID.

4. The method of claim 1, said identifier being hardcoded within said second group of unmanaged code.

5. The method of claim 1, said managed code and said unmanaged code being callable from a document environment.

6. A computer readable medium comprising computer executable instructions adapted to perform the method of claim 1.

7. A method comprising:

detecting that a document has been opened, said document comprising managed and unmanaged code adapted to be executed within a document environment;

executing said managed code, said managed code comprising an identifier and a type library; and

executing said unmanaged code, said unmanaged code adapted to;

search for said type library using said identifier; and

call at least a portion of said managed code using said type library.

8. The method of claim 7, said managed code being adapted to load said type library in a running object table.

9. The method of claim 7, said type library being located in a file.

10. The method of claim 9, said identifier comprising a directory path for said file.

11. The method of claim 7, said identifier comprising a GUID.

12. The method of claim 7, said calling comprising identifying an instance of said document from which said at least a portion of said managed code is being called.

13. The method of claim 7, said managed code being adapted to detect that said unmanaged code is adapted to call said managed code.

14. A computer readable medium comprising computer executable instructions adapted to perform the method of claim 7.

15. A method comprising:

receiving an identifier for a type library within an unmanaged code environment, said type library comprising a reference to a managed code environment;

searching for said type library using said identifier;

finding said type library in a running object table; and

making a call to said managed code environment from said unmanaged code environment using said type library.

16. The method of claim 15, said identifier comprising a file name.

17. The method of claim 15, said identifier comprising a GUID.

18. The method of claim 15, said managed code environment and said unmanaged code environment being called from within a document environment.

19. The method of claim 18, said making a call comprising an instance identifier for said document environment.

20. A computer readable medium comprising computer executable instructions adapted to perform the method of claim 15.
