bmp to screen
There's this great thing called a "search engine" that can often answer your questions! If that fails you, you could always look in the selection of articles available here for info on DirectX.
Since I'm feeling helpful today,
Here if you don't care to use ID3DXSprite, or here if you do want to use it (and have a Gamasutra membership).

My beautiful texture manager, supporting various API's has routines for manipulating various image formats such as 24bit bitmaps. Following this is a code listing. However, I highly suggest you learn to use search engines and utilize site's such as gamedev's articles.
/* Please forgive me, if the bitmap related code has possible bugs, none have been detected yet; as I have been using other formats, previously and have just added support for BMP's. */
