LoadExternalModule throws error (-7 Unknown file extension) when working with source-code.

Question

Utility library function LoadExternalModule (admittedly marked as obsolete - but key to one of our older software)
fails with error code (-7 Unknown file extension.)  in CVI 2012SP1 and 2013 Version 13.0.0(647) on Win7
The suggested alternative Win32 API GetProcAddress doesn't work with source or obj files (so isn't an alternative at all)
The Target-Settings to "Enable LoadExternalModule" are already checked.
Any suggestions ?
This code-snipped shows the behavior :
// File "Main.c"
#include <utility.h>
int main(void)
void (*funcPtr) (void);
int moduleID;
int status;
// Library-Function-Error : -7 Unknown file extension.
moduleID = LoadExternalModule ("Test.c");
funcPtr = GetExternalModuleAddr (moduleID, "test_function", &status);
(*funcPtr) ();
return 0;
// File "Test.c"
void test_function(void)

Hi,
Thanks for teh inf regarding the LoadExternal Module,
Using the LoadExternalmodule as you mentionned requires using a .obj file but this lead me to an issue getting a Control value from an .obj file called from a dll
When using the LoadExternalModule function in CVI 2013, we can no longer use a .c file. Instead we have to use an .obj file.
My issue is that' impossible for me to get a control value from an .iur managed by the .obj witchi is called by a dll. 
Otherwise it's impossible for me to get the control vale when calling the .obj from a dll.
Any suggestions Amigos
Thanks
