c# - Is there an event in .NET for when default audio input changes? -


I am using System.Speech.Recognition in Windows 7 so that the user has a program Recognition code is integrated into the program by controlling voice commands. Now, the recognition engine program is built on startup and the user has been rebuilt on making changes to voice recognition language. All this works well.

Recently we had an issue with the creation of a validation engine if the system changes during the running of the default audio input program, then we have no way to answer it. In particular, if the mic was unplugged, the engine would not be able to get input when the program started. I go to a disabled state if Mike gets plugged in later, then I would like to keep the program in mind and update the engine.

Is there any disclosure for changes in system default audio input?

You need to implement, and call IMMDeviceEnumerator :: RegisterEndpointNotificationClall people for this one C # is the cover; I see it.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
