It doesn't make sense to pass the info as WM_INITDIALG parameter if it's
going to be stored in global variables anyway. A better way would be to
store this in the window info.

Any pointers on what's the set of winapi functions used to store and
retrieve data in windows? I've searched MSDN for almost 30 minutes and
no luck.

Try SetWindowLongPtr [1] / GetWindowLongPtr [2].
You probably want to use the W variants of the functions, though the
A/W distinction doesn't make much sense in this case.

SetPropA/W

Also offset 0 of the window longs are usually used, like e.g. in
comctl32/tooltips.c:

SetWindowLongPtrW (hwnd, 0, (LONG_PTR)infoPtr);
