Does anyone know this?

[john]

Hello,

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

Method 'Public Function CamEventCallbac kFunc(eventID As Integer, pData As
Integer, DataSize As Integer, Context As Integer) As Integer' does not have
the same signature as delegate 'Delegate Function
DelegateCDRegis terEventCallbac kFunction(hSour ce As Integer, pFunc As
Integer, Context As Integer, ByRef hFunc As Integer) As Integer'.

Delegate Function DelegateCDRegis terEventCallbac kFunction(ByVal hSource As
Integer, ByVal pFunc As Integer, ByVal Context As Integer, ByRef hFunc As
Integer) As Integer

Declare Function CDRegisterEvent CallbackFunctio n Lib "CDSDK.dll" (ByVal
hSource As Integer, ByVal pFunc As DelegateCDRegis terEventCallbac kFunction,
ByVal Context As Integer, ByRef hFunc As Integer) As Integer

err_Renamed = CDRegisterEvent CallbackFunctio n(m_hSource, AddressOf
CamEventCallbac kFunc, 100, m_hFunc)

Re: Does anyone know this?


Make sure the CamEventCallbac kFunc method signature ends with

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

rather than

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