User Data and Dialog Boxes: Help Needed

[Mitchel Soltys]

I'm fairly new to windows programming, so this is hopefully a simple
question.

What's a good way to pass information to a DialogBox().

For example I've got a general dialog box that I want to use for selecting
items
from a list. I have several lists that the user might choose from. What
I'd like to do is pass in a title for the dialog box and a pointer to the
list of strings to choose from when the dialog box is created, but the
DialogBox function doesn't appear to have any type of parameter to support
user data. (I've heard that win95 has another version of DialogBox, but I'm
interested in an app for win 3.1 (16 bit)).

The only way I know to get around it is through using global variables,
yuuck. Any help would be much appreciated. Thanks.

"DialogBox" doesn't, but "DialogBoxParam" does!

In case of mfc programming under vc++, you have an own from CDialog
derived class with some member variables in it. You would bring the box
to the screen via:

CMyDialog d;
d.my_member_variables = ...
d.DoModal();

where the automated DDX-functions would do the rest for you, if you
choose to connect the controls in the box to the member variables using
Class Wizard.
