This allows COM objects to implement powerful back-ends to simple GUI front ends such as Visual Basic and ASP. The file format for .EXE files are similar to .DLLs, and both types of files contain code, data, and resources. For more information, see the Knowledge Base article "PRB: Problems Occur When Defining _AFX_NO_XXX" (Q140751).
However, if an application tries to access a dll file that has been corrupted or is missing, that program will no longer work. Addison-Wesley Developers Press, 1997. While the DLL code may be shared, the data is private except where shared data is explicitly requested by the library. Only MFC executables (either applications or regular DLLs) that are built with the shared version of MFC can use an extension DLL.
The developer can catch the error and handle it appropriately.

This notion of building up the operating system from a collection of dynamically loaded libraries is a core concept of Windows that persists as of 2015[update]. It is not possible to directly execute a DLL, since it requires an EXE for the operating system to load it through an entry point, hence the existence of utilities like The index of the found name is then used to look up the ordinal in the Export Ordinal table. The created executable then contains an import address table (IAT) by which all DLL function calls are referenced (each referenced DLL function contains its own entry in the IAT).
That function must be called from each of the regular DLLs that use the extension DLL. It is part of visual studio but it will allow you to view DLL file in great details.

This could be used as an indirect form of inter-process communication, or it could accidentally corrupt the different programs.
Explicit run-time linking DLL files may be explicitly loaded at run-time, a process referred to simply as run-time dynamic linking by Microsoft, by using the LoadLibrary (or LoadLibraryEx) API function. DLL compilation will produce both DLL and LIB files.
