Hex Edit Control with Input and Length Checking

Environment: VC6

I don't know how many times I've wanted to put a hex edit control in my application, but wanted to limit the user's input and length. CEdit only has the ability to limit the input to numbers. That's all fixed now with my program, CHexEdit class. The following features are supported in this program:

  • Limit input to upper case, lower case, or both cases
  • Increment and decrement max input length (1-16 characters)
  • Convert hex string to decimal

    bullet and write one myself). And there it was!!!

    Thanks for sharing, this class will get lots'o'work.

    If you are looking for suggestions, I made a small
    change to the OnChar() method. Basically, instead
    of ignoring, say, lower case when case is set to
    only upper case, I converted the character to upper case.
    That way, the user can type either 'a' or 'A' and an 'A'
    will appear in the text box (ease of use type of thing).
