In the COM world, the VARIANT data type is a giant union!! Cool, isn''t it
That''s why it can store all those different data types.-nt20
Unions also have another BIG role in almost all of Microsoft''s new technologies.

I''ve always known what unions were, but never what to do with them... The example of having both a float and an int in the same one gave me a great idea (probably not a new one). I always make horribly complicated classes for variables in my scripting language(s) that remember what type they are and behave accordingly. I could replace all that with a simple union! hehehe thx

An alternative to the RGB macro...
union RGB{ unsigned long composite; struct { unsigned char r; unsigned char g; unsigned char b; }}//..........RGB myColor;myColor.r = 82;myColor.g = 255;myColor.b = 9;if(myColor.composite == RGB(82, 255, 9)){ //This code WILL execute...} This topic is closed to new replies.
