I'm using 3.5. The strange thing is that after some more testing, it's only when I'm using GPSGate to simulate the input data that I get this error. I've run it with a normal BT GPS Unit and it works ok.
Does the file exist on your system? Can you load it manually with the LoadLibrary dll?
Sample is
Private Shared Function LoadDLL(ByVal pstrLibraryName As String) As Boolean
Dim hModule As IntPtr = GetModuleHandle(pstrLibraryName)
Dim result As Boolean = True
If (hModule = IntPtr.Zero) Then
hModule = LoadLibrary(pstrLibraryName)
If (hModule = IntPtr.Zero) Then
MsgBox(String.Format("Error loading '{0}'", pstrLibraryName))
result = False
End If
End If
Return result
End Function
Public Declare Function LoadLibrary Lib "coredll.dll" (ByVal fileName As String) As IntPtr
Public Declare Function GetModuleHandle Lib "coredll.dll" (ByVal ModuleName As String) As IntPtr
