How to detect the presence of a default recording device in the system? |
|winapi|audio|device| |
How do I detect if the system has a default recording device installed?
I bet this can be done through some calls to the Win32 API, anyone has any experience with this?
I'm talking about doing this through code, not by opening the control panel and taking a look under sound options.

Windows Mobile Device Emulator - how to save config permanently? |

If i understand well your needs, i think that the best way of doing it, is to have all maps as externals of the main trunk and then make a script that recursively tags each map (external) to it's current revision in the working copy (or the server if you want it that way).

Your code looks fine,
I would use the method `ADD_NODES_AND_ITEMS` myself if I were to add nodes and items ;)
Beyond that, try to call `EXPAND_NODE` after you added the items/nodes and see if that helps.

Use `java.beans.XMLEncoder`. Its API is very simple (actually a little too simple; it'd be nice to wire it to a SAX ContentHandler), but it works on many graphs out of the box, and it's easy to create your own persistence delegate for any odd-ball classes you might encounter.

Ah thank you Theo - indeed seems I was confused there. I think the root of the confustion came from the fact I was able to assign
textInput.text = node;
Which I know guess is just implicity calling XML.toString() to convert XML->String. setChildren() is what I was looking for. |

How can you handle an IN sub-query with LINQ to SQL? |

Any help would be gratefully received.

I don't know, but this sounds like a really "hard" problem (in the sense that all real-world) problems are really hard. I bet the underlying problem is something to do with the setting of the focus. Windows that manually do that are evil and generally suffer from all manner of bugs. |
I am sure you can get to the serial number of the cpu on most os's; you could use that, after all if they transplant the cpu its safe to assume that the old machine would no longer be in use?

You need a Rank field for each product (which could also be the DisplayOrder field).

When you need to list the products, do a select query which sorts in DESC order of rank.

The basic idea is that goto gives you too much freedom to do something you didn't intend to. It can cause errors in places that don't appear to be related to the goto statement, so it makes code maintenance more difficult.

Best way to make a printer-friendly ASP.NET page? |
