Hi all,
What would be the best solution to filter input for an editbox?
I want to create an editbox which can only contain hex characters.
all other characters shouldn't be added to the editbox.
I also want to disable the OK key until enough characters are put in.
My idea: Use a GetAsyncKeyState() loop and only place the hex characters in the buffer.
Then using lstrlen i could catch the input length and decide whether the ok button should be available again.
Would this be a good solution, or are there better ways to do such a thing?
Thanks,
Mark
One of Iczelion's tutorials covers this (IIRC); subclass the edit control, ignore "illegal" characters (non-hex digits), process the rest as usual, on OK use WM_GETTEXTLENGTH to ensure the right number of characters are inputed, if so process, otherwise ignore the OK. It should be fairly easy to do.

sounds easy enough.
I will check the tut's.
Thanks!
