I have a windows form, where different usercontrole forms can be loaded within a panel.
These (sub) usercontrolform have button that should talk with the serialport control on the main form.
For example a button should turn on a relay that is connect to my serial port. The communication works fine if i use everything on one form, but now i want to do this from the sub usercontrol form.
I tried to do this via addhandler and properties, but i can't get it to work.
Any help would be great.
Thanks in advance.
