So where will it be sitting? A UserControl by definition is an activeX control, there isn't any other sort. In order to function it has to be sited within a container that supports such controls, examples of these are a form, a picture box, Internet Explorer pages such as html, asp etc and also other applications may allow activeX controls to be sited on them. So your control must be sited somewhere, the key then to solving this particular problem is to determine where your control is sited.
Unless I suppose you have instantiated the control in code which is a special case as this involves instantiating the classes exposed by the control rather than the UI that is normally associated with it. In this case you would simply reference the method directly.
MyUserControl.MyMethod
Where you have declared MyUserControl like this:
Dim MyUserControl As Object
Set MyUserControl = CreateObject("MyUC.MyUCtl"
MyUserControl.MyMethod "Test"
Or
Dim MyUserControl As MyUC.MyUCtl
Set MyUserControl = New MyUC.MyUCtl
MyUserControl.MyMethd "Test"
I need to use the control in Visual Foxpro - its a Tapi control as VFP isnt the best tool for working with API calls
I have a module in Visual Basic that contains all of my API declares and a function that is used by an API call to send messages back into VB
From this module I need to trigger an event on the control so that when I use it in VFP I can place foxpro code in there.
Correct me if im wrong - module events cannot be accessed when the control is used in Foxpro, Internet explorer etc.
Thanks
Addition:
In the module,the property Let/Get should be like this:
Public m_lObj As Long
Public Property Let theCtrl(ByVal nCtrl As cCtrl)
m_lObj = ObjPtr(nCtrl)
End Property
Public Property Get theCtrl() As cCtrl
Dim ct As cCtrl
If (m_lObj <> 0) Then
CopyMemory ct, m_lObj, 4
Set theCtrl = ct
CopyMemory ct, 0&, 4
End If
End Property

FormName.UserControlName.M
As you are in a module, you need to use the formname first, so for example to call the "MyMethod" method of usercontrol "UC1" sited in form "MyForm1" you would use:
MyForm1.UC1.MyMethod
With any required / or optional parameters as usual.
If you want to always refer to the current form then you can use:
ActiveForm.UC1.MyMethod
Assuming of course that the appropriate usercontrol is sited on this current form.
