Purpose |
In a Callback Function, return the numeric value of the lParam& parameter of the message sent by the caller. CBLPARAM has been superceded by the CB Callback functions, although CBLPARAM remains supported for a limited period. Existing code should be converted to the new syntax as soon as possible. |
|
Syntax |
lParam& = CBLPARAM |
|
Remarks |
When Windows sends a message to the callback, the lParam& value contains different values depending on the value returned by wMsg&. In other words, CBLPARAM returns a message-dependent value. See Dynamic Dialog Tools for more information on callbacks and messages. |
|
Restrictions |
This function is only valid inside a Callback Function. |
