Reaching in and fiddling the style bit directly is like reaching into a program's internal variables and just changing the values: All the other work that is associated wi...

A customer wanted to know how to launch Explorer's Search window with specific fixed search criteria. It turns out that there are two ways of doing this, the poor man's way and the overachiever's way. The overachiever's way is actually easier to discover. You can use the search-ms protocol to generate a command string that describes the query you...

Via the suggestion box, Sys64738 asks, whether I think is a good C/C++ programming style to add IN and OUT to function prototypes. Remember, this is my opinion. Your opinion may validly differ. I would go beyond just IN and OUT and step up to SAL annotations, which describe the semantics of function parameters in more detail than simply IN and ...

There are many ways, depending on how wide a scope you want. If there is one specific window that you want to follow right-to-left layout rules, then you pass the extended window style when you create the window.
