Hi,
I'm new to Metastock, the Forum and also to MSX.

I tried to develop a C++ - dll which uses variants for the exchange of data with COM-interface calls. I'm not as familier with C++ as with Java or C# and so I tried to free all variants with VariantClear and SafeArrayDestroy (as I have seen in some examples).

The dll works really fine with MSXTest.exe and it also works fine with Metastocks 11 - but when I'm closing the chart with the external function in it, Metastock crashes with a memory error.

If I don’t free all data variants (e.g. with SafeArrayDestroy), in my dll – MetaStock won’t abort with this error (on closing the chart). But then the memory usage of Metastocks will increase over a longer period of time.

Maybe someone out there knows such a problem and can give me a hint?

thanks a lot!
