Hi there !
I have some Problems to get a SafeArray out of a COM Server written in
(Unmanaged) C++.
From (unmanaged) Visual Basic , everything is ok , but unfortunately
in C# I get an exception.
Can anybody help me ?
Thanks a lot !!

Roland,
How are you accessing the unmanaged code? Can you provide a sample?

Sorry, but I had a little Bug in my Posting...

Roland,
Are you using VS.NET to create the .NET wrapper? Or are you using
TLBIMP, or are you coding the interface by hand?

Hi Nicholas,
I tried both, using the VS.NET and tlbimp with and without /sysarray
But everything didn´t work.

Hi
I'm creating a .NET dll, which I will use in VB 6. I have no problem
declaring methods, which will take a single Object, String, Integer and so on
as a parameter. I manage even to transfer arrays of Strings and integer, but
I fail to pass an array of Objects in a parameter. How do I declare a method,
where one of the parameters is an Object array, in .NET, which I will use in
VB6?

When there is a need to pass some dynamic information between 2 managed
assemblies, the "Dictionary object" in Generic form can be used as a method
parameter to pass the information. The information that needs to be passed
can be stored as Key-Value pairs, and the method signature remains the same.
That way, handling future requirements of passing additional details to the
callee can be handled without changing the method signature.

Hi all,
I'm calling a COM Interface method that returnes SafeArray wrapped into
variant. Is it possible to convert it to managed array? Because working with
SAFEARRAY directly is a bit complicated. Or maybe there is a managed wrapper
class for safe array?
Thanks in advance.

Hi Gurus,
I need to transfer a jagged array of byte by reference to unmanaged
function, The unmanaged code should changed the values of the array, and when
the unmanaged function returns I need to show the array data to the end user.
Can I do that?
How?

Hi all,
I need to implement an unmanaged function that gets a SafeArray and
hands it over to a managed function having the managed array-type.
Using MarshalAs I can call unmanaged functions having SafeArray from
managed code. But here I need this vice-versa...
I assume it is doable with MarshalAs magic, but how?
Thanks

I am trying to create a Java to .Net interop and the way I am doing it is by creating a C# com object and a native unmanaged c++ dll that uses JNIEnv of java.
the java is loading the native c++ dll and invokes a method in it which invokes a method on
The command passed from java to .Net is a byte array and the response passed back is also a byte array

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.
