How to write an event in c#.net using vb code(windows application)

Question

Hi all,

here i am giving vb code below.

Object = "{FE9DED34-E159-408E-8490-B720A5E632C7}#1.0#0"; "zkemkeeper.dll"

Begin zkemkeeperCtl.CZKEM CZKEM1
Height = 615
Left = 0
OleObjectBlob = "FormMain.frx":0096
TabIndex = 12
Top = 0
Visible = 0 'False
Width = 615
End

Begin VB.CommandButton cmdRestartDevice
Caption = "RestartDevice"
Height = 375
Left = 4080
TabIndex = 21
Top = 5040
Width = 1575
End

Private Sub cmdRestartDevice_Click()
frm2.CZKEM1.RestartDevice CInt(frm2.txtMachNum.Text)
End Sub

Private Sub CZKEM1_OnHIDNum(ByVal CardNumber As Long)
MsgBox CStr(CardNumber)
End Sub

In the above code i am getting success fully the cmdRestartDevice_Click() event.

But i am not getting CZKEM1_OnHIDNum(ByVal CardNumber As Long) this event.

Means i think(custom control) this CZKEM1 is created in the above code with begin and end.

How can we create that custom control in c#.net for windows application.

Please help me out...

thank you....
