Yes, VFP6, SP3. It is much faster than VFP5 of course, but is is also much slower than CreateBinary(). I can live with the time on an up to date machine, but faster is always better! If I have to, I suppose I could have one the clients C++ programmers build me a DLL or even an FLL. It would be nice however, to be able to do something in VFP, maybe using the API. I've experimented very briefly with RtlCopyMemory, but I don't think that there is any hope there. The problem is that the arrays I am getting from a VB client are arrays of integers. The VB programmer can't seem to pass me a VT_ARRAY|VT_UI1, so part of the problem is I have to CHR() each element to build a string of bytes that I can CreateBinary() to pass to a C++ COM server. It all works now, but anything I can do to speed it up is good.
Thanks for the reply.

CreateBinary() is great at the conversion from string to array but I have been having to manually convert arrays to strings,(cData = cData + aData[x]...) MUCH slower, esp. with a 50k array. Thanks in advance.
