Button Images and Saving

Hello. I'm relatively new to Windows programming and I have two questions.

Number One: Could somebody please post an example of a CreateWindowEx() function which creates a button with an image on it, rather than a caption?

Number Two: Is there a standard Windows function for showing a "save as" dialogue box? I'm creating a program that opens and saves files, and I'd like to know how to create a dialogue box that displays a file directory list and a file name box that looks similar to the ones that are displayed in Office programs when you "save as" or "load".

Thanks. Any help would be greatly appreciated.

Thank you very very much.
