A customer observed that sometimes the Entry Point Not Found error dialog does not include the name of the missing entry point.<\/p>\n

Usually, it looks like this:<\/p>\n

\n
Contoso.exe – Entry Point Not Found<\/div>\n\n\n\n\n
\u2297<\/td>\nThe procedure entry point WidgetStart could not be located in the dynamic link library widget.dll.<\/td>\n<\/tr>\n
\n
\n
OK<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

But sometimes it looks like this:<\/p>\n

\n
Contoso.exe – Entry Point Not Found<\/div>\n\n\n\n\n
\u2297<\/td>\nThe procedure entry point\u00a0 could not be located in the dynamic link library widget.dll.<\/td>\n<\/tr>\n
\n
\n
OK<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n

Why does the error message sometimes leave out the name of the missing entry point?<\/p>\n

If the entry point name is longer than 128 characters, then it is omitted from the error message. The most common reason for having a very long function name is that you exported decorated C++ functions, because C++ function decoration can result in very long names.<\/p>\n
