I got my class working by adding
Implements System.ComponentModel.ISynchronizeInvoke Do i need to add anything to the following functions?: Public Function BeginInvoke(ByVal method As System.Delegate, ByVal args() As Object) As System.IAsyncResult Implements System.ComponentModel.ISynchronizeInvoke.BeginInvoke End Function Public Function EndInvoke(ByVal result As System.IAsyncResult) As Object Implements System.ComponentModel.ISynchronizeInvoke.EndInvoke End Function Public Function Invoke(ByVal method As System.Delegate, ByVal args() As Object) As Object Implements System.ComponentModel.ISynchronizeInvoke.Invoke End Function Public ReadOnly Property InvokeRequired() As Boolean Implements System.ComponentModel.ISynchronizeInvoke.InvokeRequired Get End Get End Property |

Sorry, it choes up at
Driver.Device(INT_PROP_DEVICE).Open(0) in cls_call.CallNumber. (editing/deleting posts would be a useful feature) |

I'm trying to create a set of generic classes from the SDK .net example. Everything compiles fine but I get the error:
"Unable to cast object of type 'XXX.cls_way2call' to type 'System.ComponentModel.ISynchronizeInvoke'." It chokes up at: cls_call.Driver.Device(INT_PROP_DEVICE).Open(0) I'm not sure exactly what's going on here. Any help would be much appreciated. I've attached a link to the classes below. http://mattjan.us/cls_call.zip |
