When creating a tree view control using CreateWindowEx why is ysTreeView32 used and not WC_TREEVIEW
because if you're coding in C, WC_TREEVIEW or any other class is defined like this:
you can't have that in asm, since you can't
#define WC_TREEVIEW "sysTreeView32"
you have to declare the string in the data section, and that's why WC_TREEVIEW won't work (unless you use some macros).
invoke CreateWindowEx, "sysTreeView32"...
