Read and write into a BMP + binary data?

[nickqueen]

I need your help!
When I read a BMP file: bitmap file.
What the function can I use to read the BMP file (byte by byte, and bit by bit)?

What the function can I use to write into BMP file(byte by byte, bit by bit), in anywhere on that BMP file?
Because I 'll pass the header of BMP ( exaclly,the first 100 byte header of BMP file).

What funtion can I read a TEXT file and CONVERT it( text) into the ANSII file and(or) CONVERT it into Binary data(0101)?

Thank for help!^__^@!
