As for as I undestood problem, this way doesn't comfortable for abatu.

(I hope, you know how create DLL include all necessary dialogs or functions.)
First of all, you must decide when do you want to execute new code from DLL. After loading Exe-file but before it executing or in somewhere inside Exe-file.
It's very important moment.

Second step is:
you can create a new section for Exe-file and write mini-loader there by hands. This code will load DLL and execute function "A" from DLL. This function include all your dialogs or functions.

if no necessary to load DLL first,
for run mini-loader you must using splicing - rewrite original code in the Exe-file by jump or call command for run mini-loader. You must execute overwriting original commands. Remember always about stack and registers!

if you want to load DLL and execute new code first,
correct EP in PE header to mini-loader code in new section + return to original code in your Exe-file.

These both ways are more easy because mini-loader is very small because knows about function A only. And you can to change main function(s) rewrite DLL only.

Good luck!

Use PELib (you can find it in internet) - this library will help you to add record about import table in PE File. And then patch it how you want( it is 2 methods to call it). So ... if you are a good patch-maker you can write a code without a PELib - only a patch and use Method 2. And read my post
