I'm creating an IStream as follow:
IStream* stream;
result = CreateStreamOnHGlobal(0, TRUE, &stream);
Then I have a CImage object that I save to this stream:
image->Save(stream, Gdiplus::ImageFormatBMP);
I need to get the size of bytes written to this IStream.
How can I do this?
There is no Length or something like this in the IStream...
thanks!

This class defines members that are independent of how the templates of the class are defined. istream Class − The istream class handles the input stream in c++ programming language. These input stream objects are used to read and interpret the input as a sequence of characters. The cin handles the input.
istream and ostream serves the base classes for iostream class. The class istream is used for input and ostream for the output.
A C++ stream is a flow of data into or out of a program, such as the data written to cout or read from cin. For this class we are currently interested in four different classes: istream is a general purpose input stream. cin is an example of an istream.
IStream::Stat should do what you want.
