As you can see I have a basic, single text box. Now as of right now when the user clicks 'hide' under 'file' the whole text box disappears, and when the user clicks 'unhide' the text box reappears. Thats almost what I want it to do, the only problem is, the whole text box disappears, where as I want it to fade, where you can see the text in the text box but its uneditable. For example, if you have a checkbox which is unclickable. I'm using the ShowWindow() function but i'm guessing there is another function to do what I want done?

Thanks!

EnableWindow(HWND, BOOL);

This does both.

BTW: good to see a fellow Houstonian on the board :)

indeed. :)

Thanks alot I got it working.
