>1) Do the PRELOAD and etc. flags work under NT or are they ignored in either a load-time or run-time linking scenario, or both? If ignored in a load-time linking scenario, does the DLL get loaded into memory at the same time the application is being loaded? From what I can tell when I start WinDbg, the DLLs are being loaded before any function calls w/in the DLLs are called. Is this always the case in NT with load-time linking? Those flags are not used – DLLs (and other user-mode binaries) are paged in as needed. >2) If we have these flags in the .DEF file for our DLLs, will they be recognized by the thunking DLL when running our Win32s application in Win3.1 or will the DLLs be loaded into memory when the application starts in a load-time linking scenario? Win32s 1.1 also will demand page (unless you have disabled demand paging) so it ill only load in whatever pages are touched. >3) In a load-time linking scenario, once the DLL is loaded, it stays in memory until the application ends, true or false? In the address space, yes, but it can of course be paged out of physical RAM. Lee
