To create a custom cell

1. Call the SSAddCustomCellType function.
2. Call the SSSetTypeCustom function.
3. Call the SSSetCellType or SSSetCellTypeRange function and set the CellType parameter to SS_TYPE_CUSTOM.
4. Custom cell types are dependent on additional code in various callback functions that are specified in the SS_CT_PROCS structure that is passed to the SSAddCustomCellType function.
5. If the custom cell type supports editing, then the SS_CT_CREATEEDITORCONTROL_ARGS structure must be used to create and return an instance of a control to use for editing unless the name of the custom cell type is identical to a window class name previously registered with RegisterClass.
6. If the custom cell type uses a renderer control, then the SS_CT_CREATERENDERERCONTROL_ARGS structure must be used to create and return an instance of a control to use for rendering unless the name of the custom cell type is identical to a window class name previously registered with RegisterClass.
7. If the custom cell type does not use a renderer control, or if the renderer control does not support the WM_PRINT message, the SS_CT_PAINTCELL_ARGS structure must be used to draw the contents of the cell when the cell is not being edited.
8. If the custom cell type is intended to edit a data type other than string, the SS_CT_GETEDITORVALUE_ARGS structure must be used to return the value from the editor control and the SS_CT_SETVALUE_ARGS structure must be used to set the value to the editor control.
9. If the custom cell type uses a renderer control and is intended to render a data type other than string, then the SS_CT_SETVALUE_ARGS structure must be used to set the value to the renderer control.
10. If the custom cell type supports overflow into adjacent cells when AllowCellOverflow is true, then the SS_CT_GETPREFERREDSIZE_ARGS structure must be used to calculate and return the dimensions of the overflow.
