FUNCTION: AboutBoxDlgProc
|
|
|
|
PURPOSE: Display an "About" box with up to 3 authored lines
|
|
|
|
COMMENTS:
|
|
The first string in g_ptblItems is the title, the next 3 strings are
|
|
text for each of the static controls. If the string isn't supplied,
|
|
the the control is hidden.
|
|
|
|
Note that we don't deal with trunctaion, wrapping, etc. It's up
|
|
to the help author to be sure the lines aren't too long (not an issue
|
|
if the control is authored with HtmlHelp Workshop).
