I have read the information at MSDN relative to VARIANT. But I found it's not easy for me to get a complete view of it,especially the use of it. I only can found the basic knowledge of it. What I want to know is how to use VARIANT. For example how to change VARIANT to char or BYTE, or how to use it to send and receive data from an ActiveX, or another things.
I not only want to get the interface of it from MSDN, but also want know how do the relative functions and classes work and why. Because the knowledge in MSDN can't give me what I want. So please help me to get completely research on it and the relative functions and classes.
Thanks again for any help.
