Does anyone know this?

Hello,

I am trying to create a delegate for an upgrade but I am now getting
this error:

Method 'Public Function CamEventCallbackFunc(eventID As Integer, pData As
Integer, DataSize As Integer, Context As Integer) As Integer' does not have
the same signature as delegate 'Delegate Function
DelegateCDRegisterEventCallbackFunction(hSource As Integer, pFunc As
Integer, Context As Integer, ByRef hFunc As Integer) As Integer'.

Delegate Function DelegateCDRegisterEventCallbackFunction(ByVal hSource As
Integer, ByVal pFunc As Integer, ByVal Context As Integer, ByRef hFunc As
Integer) As Integer

Declare Function CDRegisterEventCallbackFunction Lib "CDSDK.dll" (ByVal
hSource As Integer, ByVal pFunc As DelegateCDRegisterEventCallbackFunction,
ByVal Context As Integer, ByRef hFunc As Integer) As Integer

err_Renamed = CDRegisterEventCallbackFunction(m_hSource, AddressOf
CamEventCallbackFunc, 100, m_hFunc)

Make sure the CamEventCallbackFunc method signature ends with

...., ByRef hFunc As Integer) As Integer

rather than

...., ByVal hFunc As Integer) As Integer
