I wrote a callback from a serial port to managed c++ land that works. Now I am having problems in being able to code a callback function in c# that can be called from my managed c++. I have serveral asynchronous buttons coming from the serial port that will cause different things to happen in the c# world.
Found several examples of callbacks or delegate functions in c# to c# and c++ to c++ but none from c++ to c#.
My test routine just displays the button status in a c# System.Windows.Forms.Label
Any help would be appreciated,
