It's more complicated than that. ->TypeInfoCount is set earlier on, should that be changed to a local variable or something?
Also, there are still bits on [2/4] that aren't do to with help strings, e.g. the small_no and typekind change, and all the offset renumbering.
Huw.

Yes, I think that this complicates complete constructor implementation. As the TypeInfoCount is used in a lot of places. I have to test by moving to a local variable, I believe this may lead to crashes.
Also, there are still bits on [2/4] that aren't do to with help strings, e.g. the small_no and typekind change, and all the offset renumbering.
Should I send the patch for small_no, typekind change first, which also affects the offset renumbering. I can send you the old NE tlbs which I got from DDKs, which I use for testing.
Huw.
Vijay.

The issue is that it would now be initialised in two places. Which one is correct?

Yes, though I rather suspect this is linked to the TypeInfoCount issue, so you'll need to understand that first.

I tried to split the patch for typeinfocount, smallno-typekind, and helpstring patches. The splitting is not working. I will try to check the values for typeinfocounts. Might need to check the hex structure of the ne typelib.
Huw.
