Is there a native way of determining what the localized decimal separator is? I have a combo box which I'm hacking up to be a pseudo-numeric control, insomuch as I want to be able to enter any positive real value, or allow the user to select from a set of pre-determined special values which are text. So I populate the Strings[] of the combo box with the relevant strings, and leave it to the user to enter any numeric values on their own. When the value changes, I parse the value for a numeric if it's not one of the matched strings, then re-write the parsed value back to the control to make sure whatever is being displayed matches with the value I'm tracking on my data wire. Works pretty well. The only problem is the user can of course still enter anything they want in there. If I have the strings "Fee" and "Fie" available, the user can enter "Foe" by typing it in. This doesn't cause a problem since I parse and write back to the control, but I'd like to be able to have it be more like a numeric control, where you can't enter invalid characters. Try to enter any non-numeric related character into a numeric control, you can't do it. I could easily implement this via the Key Down? event structure frame, but how do I distinguish what a valid decimal character is? In a North American locale I'd allow a "." character, but in France I wouldn't, for example. I'm aware of the %.; %,; and %; codes which help with scanning an entire string for a number, but in this case I'm trying to match only a single character and I don't think they are of much help.
