Easy way to store metadata about SQLite Database

阅读更多关于 Easy way to store metadata about SQLite Database

问题 I was wondering if there is a simple way to store meta information about an sqlite-Database in that database. I am specifically thinking about a version number that lets you easily find out which version of a database layout you are using (So my code could check if the database structure is compatible without querying SELECT sql FROM sqlite_master WHERE type='table'; and comparing the result with a predefined schematic). To clarify: I am not interested in the version number of the sqlite

I have an HTML page containing alot of meta tags and I want to parse them to find certain ones.

Framework goto definition shows comments, are these generated from xml comments?

阅读更多关于 Framework goto definition shows comments, are these generated from xml comments?

I was mildly surprised recently to discover that my carefully crafted xml comments weren't showing up in intellisense for my colleagues. Having always used the associated assemblies with project references, I hadn't realised that you had to export the .xml document as well to access this information. This led me to wondering how the .Net framework intellisense works. If I understand correctly, the .xml files must be hidden away somewhere in a special folder? But my main question is about 'Goto definition' - if you goto definition on a .Net framework assembly, you get the info generated from

Set Custom Metadata to Files of any Type

阅读更多关于 Set Custom Metadata to Files of any Type

Is there way to set custom metadata to files of any type? I want the metadata to be copied when the file is renamed, moved or copied. I don't want to use ADS. No. At some point your "metadata" just becomes "data" which should be stored inside (or with) the file itself. If you are trying to avoid having a database, but store some sort of state data with the file, you have a few options: encode the metadata in the file path (ie. use the folder name to contain the metadata) rename the file and encode the metadata in the filename create a separate file (e.g. txt or xml) and .zip it with the file

How does one add custom metadata tags to an image on the iPhone?

阅读更多关于 How does one add custom metadata tags to an image on the iPhone?

I tried adding custom entries in the exif dictionaries I received from an image. This didn't work. I'm assuming this is due to the fact exif is a standard that is already defined. Basically I am trying to create a metadata tag that can be placed in jpegs that will have no character limit. I read that XMP metadata tags do not have character limits. Is this true? If so how would I create these on the iPhone? Thank you. Boeckm I'm not sure what you've all tried code wise, but Caffeinated Cocoa has a pretty good blog entry on Image Metadata that I've used in an application for a client a while ago
