Visual C++ General
AFAIK an EXE under Win32 does not export functions.
You should create a DLL to export functions.
But how can you export a function from an exe I can export function from DLLs but i don¡¯t know how to do that in an Exe file
If i understood the poster right he has an c# dll and would like to call a function that is implemented in an exe
Or did i fully missunderstood the poster and he has an exe with that he would like to call a function that is in the C# DLL

Sounds logical... And it¡¯s also working. But i never seen that neither heard about that. And also don¡¯t see a reason to do so...
By my experience, export functions from an exe can be used:
1. Want to share a function from the exe like using dll. In this way, the calling process call LoadLibrary to map the exe into its space and get the adress of the function. Then call it.
2. One dll mapped into a host application wants to call a function provided by the calling process. In this way, the dll calls GetModuleHandle to get the handle of calling process. Then get the address and call the function.
Some people asked me if it possible to make App1 launch App2, and at the run-time, call an exported function of App2 from App1. I doubt it and never try. But I think for interprocess communication, maybe should use RPC or so.
