DLL crash error

[tj.dale]

I have finally managed to get my DLL calls working, I can call the function, and get a correct string return. however I now get a crash from esignal when exiting

The error is :-

"Exception EInvalidPointer in module mydll.dll at 00002740"

I get the same error even if I use different examples of test dlls I have got.

Anyone seen this before?

EInvalidPointer is generally raised when you try to free memory that has already been freed (or attempt to free a pointer to a block of memory that was never allocated in the first place). I would suggest that you double-check the code in the DLL.

Thanks for this Chris, I have forwarded your coments to the developer of the DLL, and he is looking at producing a DLL that does not free memory.

He has stated that I have to free the instances for the DLLs before I close the application. Anyone know what this means?

many thanks for your help so far.

You don't need to worry about explicitly unloading the DLL when you are calling the DLL from within eSignal EFS... that is handled for you automatically.
