DiscardCtrl
int DiscardCtrl (int panelHandle, int controlID);
Purpose
Removes a control from the specified panel and from memory.
You cannot discard a control in the callback function for the control, except when responding to the EVENT_COMMIT event. Discarding the control from its own callback function in response to other events might cause unpredictable behavior.
Supported Controls
You can use DiscardCtrl with all LabWindows/CVI user interface controls.
