You can mix GDI and GDI+ drawing operations in the same code path. The article INFO: Interoperability Between GDI and GDI+ (Q311221) discusses some caveats to keep in mind when you are writing code that allows GDI and GDI+ to interoperate.

See also the FAQ ‘How to create my own hatch styles for brushes’ for an example how to use GDI bitmaps with GDI+.

The most prominent functions for mixing GDI and GDI+ are the GetHdc and ReleaseHdc methods of the Graphics class.

GDI+ text layout is resolution independent, and forms built with GDI+ text look the same at all resolutions and when printed. The GDI+ APIs DrawString and MeasureString lay out text independent of device resolution, so a paragraph of text takes the same number of lines, no matter what the display device.
