Of course it's possible: you can do it simply by calling the callback or by using CallCtrlCallback () function from the Programmer's Toolbox.
If you want to directly call the callback, you must pass the appripriate parameters to the function. Remember that while in a control callback, 'panel' parameter holds the panel handle the control is on, so if the second control is on the same panel you can simply pass this variable to the function; the same happens for 'event' variable: since a button responds mainly to EVENT_COMMIT event, you can simply pass that variable to the called callback.
int CVICALLBACK FirstControlCallback (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
{
if (event != EVENT_COMMIT) return 0;
your code here...
// Call another control callback
SecondControlCallback (panel, PANEL_BUTTON2, event, NULL, 0, 0);
... your code here
return 0;
}
int CVICALLBACK SecondControlCallback (int panel, int control, int event,
void *callbackData, int eventData1, int eventData2)
{
if (event != EVENT_COMMIT) return 0;
MessagePopup "Message", "This is the second button callback.");
return 0;
}
