Anyway, here's my code now:

Thanks to your code I managed to understand how to do validation for my own code.
I wanted the user to be able to only input time in the format hh:mm.

Here's the solution:
1) I put one EditString called "e" and one Button called "b" in the layout.

2) Add this code:

// Custom character filter
class MyTimeConvert: public Convert {

	public:
	int Filter(int chr) const {
		if(IsDigit(chr) || chr == ':')                        //only accepts digits and ":"
			return chr;
		return 0;
	}
};

// Validation callback. Uses regular expressions:
void MainWin::ValidateTime()
{
	RegExp r0("\\d\\d:\\d\\d");
	if (!r0.Match(~e))
		Exclamation("Invalid time!");
}

e.MaxChars(5); // limit it to 5 chars
e.SetConvert(Single<MyTimeConvert>()); // sets custom filtering
b.WhenPush = THISBACK(ValidateTime); // when clicked check for format hh:mm.
