Sreach order for DLLs

Hi freaks

Does anyone know the “search order” of DLLs, defined in ASN-File and by signature?

Following (two) constellation:


A C-Signature  “MYDLL_SIG” is defined in UnifAce with dll name “mydll”
The ASN-Files contains to places, where the DLL is referered (okay, not good but it could happen)

Case 1
  ;via include

Case 2
  ;via include
  ;back in primary ASN

In the application shell execute trigger, there is a simple

  newinstance “MYDLL_SIG”,$01

Now I do monitor the access to the DLLs by procmon.

  Case 1: Allways the DLL under path_a is loaded

  Case 2: The startup of UnifAce loads from path_a but the newinstance is loading from path_b

So why is there a difference?
Does anyone know the logic behind this?

PS: We did “correct” this one by modifing the ASN-files, but strange it is anyway 🙂
