Found this snippet of code

[size=2][color=#0000ff]Dim[/color][/size][size=2] mscomm1 [/size][size=2][color=#0000ff]As[/color][/size][size=2] AxMSCommLib.AxMSComm = [/size][size=2][color=#0000ff]New[/color][/size][size=2] AxMSCommLib.AxMSComm
 
[/size][size=2][color=#0000ff]Dim[/color][/size][size=2] strLicense [/size][size=2][color=#0000ff]As [/color][/size][size=2][color=#0000ff]String[/color][/size][size=2] = "gfjmrfkfifkmkfffrlmmgmhmnlulkmfmqkqj"
 
[/size][size=2][color=#0000ff]Dim[/color][/size][size=2] myType [/size][size=2][color=#0000ff]As[/color][/size][size=2] Type = Type.GetType("AxMSCommLib")
 
[/size][size=2][color=#0000ff]Dim[/color][/size][size=2] f [/size][size=2][color=#0000ff]As[/color][/size][size=2] FieldInfo = myType.GetField("licenseKey", System.Reflection.BindingFlags.NonPublic [/size][size=2][color=#0000ff]Or[/color][/size][size=2] Reflection.BindingFlags.Instance)
 
f.SetValue(mscomm1, strLicense)

but now i get a NullReference exception on the Fieldinfo Variable.
I Import System.Reflection at the top of the class

Any ideas?[/size]
