Information on Linked Delay-Load Libraries

Import ViewerThe EXE Delay Import Viewer provides insight into linked delay-load libraries associated with an executable file. It presents a compilation of information about the functions that an executable imports without immediate loading. These functions are derived from Dynamic Link Libraries (DLLs), and the viewer highlights the specific DLLs from which the program imports these functions. This feature is valuable for understanding the deferred loading of functions, aiding in comprehensive analysis of executable files.

Retrieve the List of Delay-Load Imported Functions

The Delay Import table was added to the EXE image in order to support a uniform mechanism for applications to delay the loading of a DLL until the first call into that DLL. This is a better way for a loading a DLL which is rarely used. That is, the DLL is linked but not actually loaded, the operating system lets you put off loading a DLL and hooking up to its APIs until you actually call the API.

This feature does not exist in Windows 9x and prior versions of Windows NT.

List of delay load imported functions


RVA — Address of ASCII string containing the DLL name. This address is relative to the Image Base.
Name — Name of the DLL in which the imported functions reside.


RVA — RVA of an array of of 32-bit numbers for PE32, 64-bit for PE32+. The collection of these entries describes all imports from the image to a given DLL.
Hint — Index into the Export Table of the DLL the function resides in.
Name — Function names.
Bound — Relative virtual address of the Bound Delay-Load Address Table, if it exists.
Unload — Relative virtual address of the unload delay-load address table, if it exists.


Name Table — RVA of the string that must be matched to the public name in the DLL.
Time Date Stamp — Set to zero until bound; then this field is set to the 'TimeDateStamp' of the exporting DLL's 'FileHeader'.
Forwarder Chain — The 32-bit index of the first forwarder in the list of imported functions.
RVA — Address of ASCII string containing the DLL name. This address is relative to the Image Base.
Address Table — Relative virtual address of the Import Address Table.
