| re: error creating windows handle in usercontrol
Just use only ONE check box and move it from place to place when a user
selects a cell. Example: cell 1,1 is active (where the check box is located)
then when the user selects another cell like 30, 30 move the check box to
that cell. You can hold all the grid information in an array of some kind.
