The default entry point has changed from DllEntryPoint to DLLMain.
If you still want to use DllEntryPoint, you can specify the entry
point in the Project settings box, under the Link tab in the Output
category. To get there, right-click on your project, select Settings,
choose "All configurations" from the "Settings for" dropdown, pick the
link tab, choose "Output" from the "Category" dropdown, and enter
DllEntryPoint in the "Entry-point Symbol" box.
If you don't want to do that, or if it's easier to just rename your
entrypoint function, here is the new prototype:
BOOL WINAPI DLLMain( HINSTANCE hDLLInst, DWORD fdwReason, LPVOID lpReserved );

Here's an example of a function declaration using declspec:
__declspec( dllexport ) void MyFunction( void )
You'll want to do this in both the prototype and the actual definition of the
function.
