I am working within .NET I have WGS84 datum comming in at 1 sec intervals and would like to convert it to SPCS 83 and shoot it back out the second serial port.
When i build i get the following error message:
InvalidArgument=Value of '31' is not valid for 'SelectedIndex'. Parameter name: SelectedIndex
Here is a snippet of the code:
Private Sub init_grid_dropdown(ByRef dd As System.Windows.Forms.ComboBox)
dd.SelectedIndex = SPCS_83
