[skpradhan]

I have a requirement of creating a 2 dimesional SAFEARRAY of __int64/hyper. I tried to make is using SafeArrayCreate() but could not succeed. If any body has worked on it pls send me a code snipate to create the safe array and store data in it.

All codes/hints/suggestions are appreciated.

thanks and regards.

SafeArrays can only contain the VT_ types and __int64 isn't among them I'm afraid - just the standard VB 8-byte-and-less types.
Maybe you could try filling the safearray with __int64 pointers cast to longs? Sounds like a bomb waiting to go off but maybe worth a go.

Good luck!

VT_I8 is there available in MIDL for a hyper data type(__int64). I know this does not comply to automation because VB does not have any data type of 8byte int. But my requirement is for VC users ,so i should be able to use VT_I8 type in SafeArrayCreate().

pls give some pointer ,whether i m right or wrong?

Give us a piece of code. And what error does SafeArrayCreate(VT_I8,...) return?
