I was wondering, what are the dimensions of the bitmap like the STD_FILENEW you would use for a toolbar? Also, if you made your own bitmaps, would you just assign the nID member's value the ID of your bitmap you want to use? I don't think that's right because MSDN says: "Resource identifier of the bitmap resource that contains the button images.". So it doesn't look like just a regular bitmap you would create that is just one big picture. So basically, what steps would you have to take to tell it to use your custom button images? Thanks.
