prevent CGEventCreateKeyboardEvent already pressed modifier keys

Question

I'm using CGEventCreateKeyboardEvent to create and CGEventPost to post an event on the Mac. The following code works perfectly for pressing the 'a' key.

CGEventRef downEvent = CGEventCreateKeyboardEvent(NULL, 0, YES);
CGEventPost(kCGHIDEventTap, downEvent);
CFRelease(downEvent);

The problem lies in the fact that the user might have a modifier key pressed. For example when the user already has the Command key pressed while my keyboard events are send, Command + a will be sent to the active application in stead of just the character a.

Is there a way to work around this? Can I explicitly say that I want to post a character, ignoring any (modifier) keys that might have already been pressed.

Did you try setting the event's flags to 0?
