what HEAD error means?

[meuh]

Hi,
I'm trying to developp a bench test using a device that communicate through serial RS232. I used an active X component that comes from another application in order to create a driver. Unfortunately when I execute my program the debug windows says : "HEAP[essai er1.0_dbg.exe]: Invalid Address specified to RtlFreeHeap( 00140000, 0042BF5C )"
What does this error means?
Yours faithfully
Katia

Hi Katia,
Heap refers to a memory space for dynamically allocated variables (pointers...). Your error sounds like a desallocation error. Are you sure you are closing reference to your activeX control when you are exiting your exe ?
We do not have enough infos to help you much.
if you have not solved your problem, please attach a sample code which erproduce the problem and indicate the CVI version you uses.
