Suggestions on how to add the functionality to import Finale music files on an application? |
|parsing| |
I'm working on a music writing application and would like to add the functionality to import Finale music files. Right now, the only thing I know is that they are enigma binary files.
Does anyone have any suggestions on where I could start so that I could be able to parse through these types of files? |

"embedded programming" is a very broad term. AVR is pretty well in that category, but it's a step below ARM, in that it's both simpler to use, as well as less powerful.

Unfortunately, my main development environment is Linux + GDC + Tango, so I don't have conio.h, since I don't use DMC as my C compiler.

If you've lots of different instances of this problem to solve, I've had some success with [Apache Ant][1] for this kind of copy/update/backup kind of thing.

I'm a big fan of Restlet, but I usually use it to implement apps whose primary role is to **be** a RESTful web service. It sounds like you're looking to add a RESTful API to an existing application.

IsAssignableFrom() tells you if one type can be assigned to a variable of another given type (may be the same type).
GetInterface() gets a System.Type object representing the specified interface.
You didn't specify what you were trying to accomplish so I couldn't tell you which is better. |
If you just want to see if a type implements a given interface, either is fine, though GetInterface() is probably faster since IsAssignableFrom() does more internal checks than GetInterface(). It'll probably even faster to check the results of Type.GetInterfaces() which returns the same internal list that both of the o... |

A good index is something that you can rely on to be unique for a specific table row.
One commonly used index scheme is the use of numbers which increment by 1 for each row in the table. Every row will end up having a different number index. |

If you subclass then intercept the WM_PASTE message you can do what you want, throw the message away to prevent the paste, manipulate the clipboard data, whatever. |
