Hi,
How do I convert a byte[] to an object[]?
I am trying to use IADs PutEx and the last parameter required a variant
array.
Thanks,

Copy each element to an object[]. I take as granted that you really have
to do this, 'cause it's not going to be efficient. :)

I suspect what you need is:

PutEx(..., new object[] { barray });

Hi Ben,
Thanks for the suggestion.
What I did to make it work is:
object[] objArr = new object[1];
objArr[0] = barray;
PutEx(....,objA rr);
As I am just learning C# so I am not so familar with your syntax. Is it
doing the same?
Thanks,
Alex

Hi Peter,
I did manage to convert byte[] to object[] using Arrays.Copy but it does not
solve me problem. Actually PutEx is expecting an object array containing
byte array. Doing that so my problem.
Thanks,

Hi Alex,
Thanks for your feedback.
Actually your code works the same way as what Ben provided. "new object[] {
barray }" means creating an object array with length determined by the
number of elements in {}. Since there is only one element "barray" in the
{}, the object array will have length "one". Also, in this one element
object array, the only element is a reference to the byte array. This is
the same logic as your code does
Thanks.
Best regards,
Jeffrey Tan

Yes, the compiler will expand
new T[] { t1, t2, ... tn }
into
T[] temp = new T[n];
temp[0] = t1;
temp[1] = t2;
temp[n-1] = tn;
and use temp in the original function call

Hi All,
Basically my situation is this, I have a server implemented in C++,
unmanaged code, using proprietery protocol over TCP/IP to communicate
with the cilent(c++ also).
Now, I am implementing the another client in C#. Server side can not
be
changed :(
So, I am using tcp/ip sockets. In the end I get byte on the client
side, which originally was some C++ class object, converted to byte
array.

From python manual
str( )
Return a string containing a nicely printable representation of an
object. For strings, this returns the string itself. The difference
with repr(object) is that str(object) does not always attempt to
return a string that is acceptable to eval(); its goal is to return a
printable string. If no argument is given, returns the empty string,
''.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
