Hi,

Extremely sorry...thx a lot.. It worked...

But can u explain the reason behind such multi-faceted behaviour ...When
the same compoennt is called thru VB it works but when called thru .NET
it fails...That means I have to go and replace SafeArrayCreateVector
with SafeArrayCreateVectorEx every where it is referenced in my
component..

Instead of

     lpSafeByteArray = SafeArrayCreateVector (VT_UI1, 0, sizeof
(MessageHeader) + (lnAccessListCnt * sizeof
(tagUserAccessControlList)));

try

     lpSafeByteArray = SafeArrayCreateVectorEx (VT_UI1, 0, sizeof
(MessageHeader) + (lnAccessListCnt * sizeof (tagUserAccessControlList)),
0);

I am facing a problem while invoking a com ( developed in VC++) method
from .NET, I have enclosed below both VC++ & .NET Code, when i invoke
this component from VB 6.0 it works fine and both the out parameter
pvarAccessList & pvarErrorMsg gets filled and returned properly.
pvarAccessList returns a byte array and pvarErroMsg returns a string ...

But when invoked thru .NET it gives error msg
"SafeArrayTypeMisMatchException Specified Array was not of expected
type"...

My head is getting sore from too much debugging... can any one shed some
light on this...
