Possible to turn OFF Unicode support for .NET TextBox?

[SoftwareEng]

I am writing a VB.NET (2005) front-end to a DB that doesn't support Unicode. I need to turn off Unicode support for my TextBoxes, so that Windows will automatically convert the unsupported typed or pasted chars to "??????" (Windows does that, I hope you know

This shouldn't be a one-char at a time check but rather a property or setting, or maybe a font that doesn't support Unicode?..


Any ideas? Thanks!

I don't think that there's a simple property/override that will help you here, as the System.String type inherently supports unicode characters. Your best bet is probably to handle the TextChanged event, if you want these characters to be updated immediately after typing/pasting, though I know you said you were trying to go for something else.

This is not bad =). This handles all ways in which the text could change. Then, I could search the entire string and mask out unsupported chars.

But still, maybe someone is aware of a setting/hack/override/font to disable Unicodeness?

Just like those. Our DB is not for the faint of heart

Your DB apparently isn't also for anyone speaking languages other than English. Unicode support should be a requirement for any app written in the past 5 years if not longer.

If you really want to hack it, you could do something like:

It is an internal system supporting on-site employees in America. But we'll probably use something other than a dumb char type in the future =)

Tencntraze,

Thanks for the code!

Could you use a .NET regex validator for this? I'd think that would be the simplest way to do it.
