Hi,

I have a VC++ COM DLL which is making calls to C#.net DLL. The C#.net DLL
functions which are byte array expecting SAFEARRAY from VC++ DLL. VC++ DLL
get called from my VB client where I need to pass this SAFEARRAY as VARIANT
to VB.
Could anyone help me how to get byte array from C# into VC++ and pass it in
VARIANT to my VB client application.

The current code I wrote seems not working can anyone help me in this -

SAFEARRAY *psa;
SAFEARRAYBOUND aDataItemBounds[1];
aDataItemBounds[0].lLbound = 0;
aDataItemBounds[0].cElements = nLength;

psa = SafeArrayCreate( VT_ARRAY, 1, aDataItemBounds );

// call to .net method
pInet->DotNetMethod(&psa, &lResult);

// copy into VARIANT to send to VB client
SafeArrayCopyData( psa, pVariant->parray);

Can anyone send me the code snippet for the above if it is wrongly coded.

I dont think .Net can understand SAFEARRAYS.
In any case, it would be better to pass a normal array to the .Net method,
then pin it and copy its contents to a SAFEARRAY.
