I've created a basic speedometer to read the time and date in real time, also created a program to read the MPH from the GPS calls to knots then deciphered it. I am pretty much stuck at this point trying to make the speedometer needle read the value of the MPH and show it accordingly by moving. Still new to GUI but its a learning experience for me. here is the needle code: GUICtrlSetGraphic($meter, $GUI_GR_LINE, $xpos + 45, $ypos + 45) here is the full GUI source code SOLUTION POSTED AT BOTTO
