This message queries the maximum number of bytes that a multi-line entry field control can contain.
Syntax
param1 ULONG ulReserved; /* Reserved value, should be 0. */ param2 ULONG ulReserved; /* Reserved value, should be 0. */
Parameters
- ulReserved (ULONG) - input
- Reserved value, should be 0.
- ulReserved (ULONG) - input
- Reserved value, should be 0.
Returns
- lSize (LONG) - return
- Maximum number of bytes allowed in the MLE.
Remarks
The multi-line entry field control window procedure responds to this message by returning the current limit set, either by default, or by MLM_SETTEXTLIMIT. If the limit is unbounded, a non-positive value is returned.
Default Processing
The default window procedure takes no action on this message, other than to set lSize to 0.
