DM_ENABLEREDRAW

The DM_ENABLEREDRAW message is sent to the dialog manager to enable or disable dialog redrawing.

Param1

TRUE - enable dialog redrawing
FALSE - disable dialog redrawing
-1 - get current state of counter of output locking.

Param2

Return

Previous state of counter of output locking.

Remarks

This function is used to prevent excessive dialog redraws when modifying multiple dialog items. Calling this function with Param1 = TRUE increments an internal counter, and calling with Param1 = FALSE decrements the counter. The dialog is drawn when the value of the counter is zero. This is normal behavior for embedded manipulations. Typical usage:

Info.SendDlgMessage(hDlg,DM_ENABLEREDRAW,FALSE,0);

// here we change lots of headers

Info.SendDlgMessage(hDlg,DM_ENABLEREDRAW,TRUE,0);
