Jason,

I work with Malcolm, and after reading this post, I notice that a small
detail may have been left out.

Malcolm wrote the code for this control, however, I have been using it lots
lately.

Normally there is two tables associated to the control. One table will
contain a field which stores a bitmask, and the other table will contain the
data used to populate the text associated to each checkbox used to represent
the meaning of each bit.

Example:

Say table one from the above description may be:

LOGPARAMS
LP_PROCESSNAME VARCHAR(16) NOT NULL,
LP_LOGMASK SMALLINT NOT NULL /*Store the bitmask as per user selection
of check box*/
....

Table two from the example above may be:

LOGLEVELS
LL_ID D_NOT_NULL_ONE ,
LL_DESCRIPTION VARCHAR(16) NOT NULL /* Data used for the construction of the
checkbox list*/


Hope I have not confused you.
