how to force redraw?

[psycik]

Set up some sort of update variable and have it set to false.

Code:

public bool needsRendering()
{
// TODO: Add needsRendering implementation
    if (updateScreen)
    {
         return true;
         updateScreen= false;
    }
    else
         return false;
    return updateScreen;
}

Then when you timer does it's thing set updateScreen to true. That will trigger needsrendering, then you can reset it back to false;

Or as part of NeedRendereing you can test the value of your timer against something rather than wait for the timer event to kick off (if that's what you are doing).
