Hi,

I am trying to enter a set of characters in text box in mfc dialog application.

In this text box, the condition is I should enter '*' only once. I can use '*' any where in text box. And if I use the same character('*') again, that entry should be disabled. That character should be disabled once the character is used.( keyboard button should not work ).This should work only after I use this character('*') for once.

Hoping for a speed reply

Thanks in advance

you can use Regex for that,alternately also can use textchanged event of textbox.But i prefer the first one must.
