Hi,
I was wandering if I can affect the color or shapes of the caret of any text box system wide.
I noticed that the caret looks different in every program, and varies even more in some websites.

So my main question is, does all text box carets have the same handle? can I affect them all globally?
And if so, how can I perhaps change the caret's color, or add a bitmap/color overlay to it, in vb.net (i'm using vs express 2012) ?

The purpose is to change the color of the caret based on the current keyboard language (for systems with 2 or more languages), as an indicator, so you will always know via the caret color, what is the current language.
I also didn't find a way to detect the current language in vb.net, so I would appreciate some help with that also.
Up until now I was programming with VB6, and I found online how to do this with it, but I want to move to .NET and the transitioning isn't so simple for me...


I hope I managed to explain myself.

Thanks!
