I have modified .odl file of a VC++ project to add some properties, so that the properties will be accessed from other VC++ projects.

How do i generate .h and .cpp file for this modified .odl file, so that i can refer these .h and .cpp file in the other VC++ projects.

.cpp file contents in the referring project looks like below....
I just want to add similar kind of code to my new properties. Is this code automatically generated...? but i am not sure how to generate it

BOOL CTrialScreener::GetEnabled()
{
	BOOL result;
	GetProperty(0xf, VT_BOOL, (void*)&result);
	return result;
}

void CTrialScreener::SetEnabled(BOOL propVal)
{
	SetProperty(0xf, VT_BOOL, propVal);
}
