I'm trying to make a memory match game in HTML5 canvas with kineticJS. But when I click on a card on the stage it gives me an
Uncaught TypeError: Object #<Object> has no method 'drawScene'
and I can't figure out why. It happened after I added the event listener to the makeCards function and made the clicker() function.

Handling events in VB6: Initialize
Here is my question. I have VB6 class FirstClass. In SecondClass i create instance of FirstClass:
WithEvents fClass as FirstClass
...
Set fClass = New FirstClass
Ok. Also in SecondClass I have an event Initialize - this is some event of FirstClass's object (as far as i can understand). But when I paste breakpoint in this event, it doesn't fire. So could you please explain me why I can't go in this event and how the events handling works in VB6 in general.
Please, ask questions if my English isn't good for understanding my thoughts
Update:
Here is property from FirstClass:
Private Property Let IRPCAppMode_Application(RHS As Object)
Const METHOD_NAME As String = "IRPCAppMode_Application" 'DO NOT TRANSLATE
On Error GoTo ErrorHandler
Set mApp = RHS
Set m_objRPCProject = mApp.Project
Set m_objDataSet = m_objRPCProject.CurrentDataSet
RaiseEvent Initialize
...
I know that mApp object sets only in this line of code, that's all. What i can't understand is how Initialize Event rises in SecondClass and how can we set private property outside of class. Calling of Initialize in SecondClass:
Private Sub m_objTestMode_Initialize()
Const METHOD_NAME As String = "m_objTestMode_Initialize" 'DO NOT TRANSLATE
On Error GoTo ErrorHandler
Dim lLoop As Long
Set mRPCProject = m_objTestMode.Project
SetupAutoSaveTimer
SSTab1.Tab = 0
SSTab2.Tab = 0
Set m_objToolManager = m_objTestMode.mApp.ToolManager
Set g_objMonDrives = New clsMonDrives
Set g_objTrendMonDrives = New clsTrendDrives
....
