Is it better to use HBITMAP or LPBITMAP as a pattern when working with/managing BITMAPs in a Windows application?
Posted on 2015-01-10
Hi:
I'm building an utility application which reads in a bitmap and then performs analysis on it.
As matter of implementation/design patterns, is it better to store, use and pass as a parameter an
HBITMAP or an LPBITMAP?
I know that I can retrieve an LPBITMAP from an HBITMAP via the GetObject() call.
I'm not sure how expensive it is to use that call repeatedly.
What's the more accepted practice to use?
HBITMAP or LPBITMAP?
Thanks,
JohnB

That will depend on whatr you want to do with that parameter. If you are already manipulating that bitmap and pass the data to a subroutine to process it, it'd be better to use a LPBITMAP, since the subroutine would have to call 'GetObject()' itself each time. If you are passing the parameter as merely an 'informational' value (i.e. not working on the data, a HBITMAP seems more appropriate. Windows will lock the data in memory internally when you call 'GetObject()'. On the other hand, that practice was recommended whan computers ran Win9x and had considerably less memory than today, so you might not even remotely run into issues, but it's always nicer to be easy on the OS' resources.
