Hi,
I developed an OCX in VC++, wich takes a VARIANT as parameter and
return a Long as the result of the operation. This VARIANT cames from
a client VB6.0 wich send an array of Byte as a VARIANT, so acomplish
Autonmation std.
I need to access the array inside the variant to load an user-defined
struct with it. To do this I used the myvariant->parray.pvData but it
didn't work. It seems that the data wasn't there...
I tried with...

I have a byte of binary data received from a NetworkStream (C# code) that I need to pass to the IWMWriter object in a DLL written in Managed extensions for C++ (since the Windows Media SDK is not usable in C#) whose WriteSample function takes a byte* parameter
Do I need to marshal data? I thought I did, so I ran into alot of issues with converting the byte to a string and then, in the MC++ DLL, marshalling that to an IntPtr via...

hello,
I'm allocating a byte-Array in C# with byte byteArray = new byte;
Now I want to pass this byte-Array to a managed C++-function by reference,
so that I'm able to change the content of the byteArray and afterwards see
the changes in C#.
(if you wanna know more details: the goal is to write the content of an
existing char-array in c++ precisely into the passed byteArray, so that
after the function has proceded the content of the...

application written in VB6 has a DLL function that passes an Array of
Variants to another function. We're planning to put a Web Service as a
bridge to unglue the 3-tier architecture ...

I'm very confused with this. I have a .NET web service that I am trying
to pass a variant byte array to from the client side. If the signature
of the web service is set to accept an Object it seems to pass it in
but I can't access the array that should be in there. If I set the
signature as a byte array I get an error in webservice.htc. It seems to
be trying to encode the variable to base 64 and it fails when trying to
do a .length on it....
