Child Tries To Delete A Character From A Previous Field?

May 3, 2010

I am making a small and very simple game that is ment to help children learn to recognise letters. I have come to a stop as I have 3 text fields. When something is entered into the first field, the program will set focus to the next text field. The problem is when the child tries to delete a character from a previous field as the focus is already set to the next text field. I want it to delete the character from the previous field when the backspace bar is hit. Any suggestion how this might be done?

I am working on a sub that essentially needs to open a text file, and replace all instances of a certain character with a unicode character.

Treat Unicode Character Plus Diacritic As A Single Character?

Aug 23, 2010

In my VB.NET application I compare words that are recorded using IPA, many of which have many diacritic marks. In one of the comparisons, I compare the words character by character.
