Hi everybody,

by checking out the use of include files in VFP 6 I found the following problem:

I created incfile.h:

#define TEST_DEFINE 1

There is a program file using incfile.h as include:

#include incfile.h
#IF TEST_DEFINE = 1
  =MESSAGEBOX("first message",64,"Whatsgoingonhere")
#ELSE
  =MESSAGEBOX("second message",64,"Whatsgoingonhere")
#ENDIF

Running the program in VFP environment, I will see the first message. After changing the value of TEST_DEFINE in incfile.h, I will always get the first message. Even the deletion of incfile.h is ignored by VFP 6.

The definition of the constant TEST_DEFINE seems to be somewhere in memory (CLEAR ALL, RELEASE ALL, CLOSE ALL have no effect). Where are the constants? Will the inclusion only be actualized by recompiling the project? I do not use the project manager. How can I force the inclusion for every execution of the program?

On playing around, suddenly the second message appeared. Unfortunately I cannot reproduce this behavior.

Thanks for hints!
