CheckBoxes in VB6

[thatbox]

I need CheckBoxes that have an extra state: X. The default CheckBoxes can only be checked and unchecked -- is there another object designed for this? I'm a semi-noob in VB, sorry. Any help will be greatly appreciated!

If you're looking for tri-state check boxes where one is checked, one is not, and the other is grayed over (like in an installation package where you install some of a products sub features but not all), then vb's current checkbox control will not support this by default, at least not in my current memory

You can get it to do what you want, but it'd be tricky. If you're a semi-noob in vb, I wouldn't recommend trying it You'd have to subclass the WM_PAINT and WM_CLICK messages to get it to do what you want as well as use a module level variable. www.vbaccelerator.com has an excellent subclassing dll that'd work perfect. But you'd have to figure out how to do the rest of it on your own. It'd be a combination of a subclassed & owner drawn control.

BTW--if you don't know what subclassing is----you intercept teh default windows messages to a control to apply your own behavior for those messages instead of using the controls' default responses to those messages. Again, if you're new to VB, I wouldn't recommend this way.

The other alternative is 3rd party controls---i'm sure there's some out there that support what you're looking for.

Actually, VB6 does support checked, unchecked, and greyed, but unfortunately a user can't grey a box by clicking twice. I've seen these things before, with blank, checked, and xed (an X instead of a check). I can imagine how you'd do it with heavy programming (lots, including making a few pictures of a box with an X to display after the two clicks, right?) but I'm just not there yet. Any idea where I could find a good index of third party controls to look through?

You can just use the image object and change the pictures OnClick().
