New Post: Maskedtextbox define culture for mask

I'm trying to make sure that my decimal point in a mask is always displayed as a dot and ignore the system's region.

As is my understanding this can be set using the FormatProvider Property of the control, but I can't seem to get it working.

To give an example, I am using a mask of type "AA AA AA AA . AA AA AA AA". The dot in the middle must always be displayed as a dot.

Any ideas?
