This is a double header

hi

 I have been trying to write a DOOM WAD editor for a few months and
have hit several dead ends.  please help if you can thank you.

 [1] Where in the Delphi help or on the web is there a guide to making
DLL with D4
I want to put the WAD file reading functions in it.

[2] Any in depth graphics manipulation for displaying the level
alowing for the movment of objects and insertion and deletion based on
position etc..

TIA, reply to this message
