MS Flex Grid control (continued)

Below I put the contents of the CGRID and reposted the use of CGRID, the original file of this article comes from the flex_grid_src.zip file on www.vchelp.net. For the use of CGRID, it has been modified, because you don't know the original author, look at the amount.

Where cgrid.h and cgrid.cpp are encapsulation of cflexgrid, CDLGUSERMANGER is using CGRID
