Hi,

I have the following program. On the main form you can search for customers by a button.
I have created a aciveX dll with a class customer and a methode getCustomers. when this methode is called (from the main form) a (child)form is shown with the data for different customers shown in a flexgrid. when I double click on the flexgrid I want to change data on the parent (main) form. The child form should not close so that you can click on an other customer.

I have created the class in an activeX dll because I want to use the same functionality behind other forms.

How can i get the data from the child form to the parent.( I think this is the easy part) How can i trigger the parentform to update the parentform when the flexgrid on the child form is clicked?

Any help would be appreciated.

You can raise an event in the ActiveX class by calling a function in the child form which will then be fired in the parent form.

Here's an outine of what you will need to do:
e.g.
In your exposed class define an event

Public Event SelectedCustomer(CustomerName As String, CustomerId As String)

'Also define a function that takes the Customer details as parameters

Friend Function PutCustomer(CustomerName As String, CustomerId As String)

            RaiseEvent SelectedCustomer(CustomerName, CustomerId )

End Function


'Call the PutCustomer function on the double click event on the FlexGrid with the required parameters.


'In the parent form Declared the ActiveX class with events.

Private WithEvents MyClass as cCustomerSelectClass

'Somewhere in the code
Set MyClass = New cCustomerSelectClass

You will then be able to access the event from code as

Private Sub MyClass_SelectedCustomer(CustomerName As String, CustomerId  As String)

    'Do something here wiith the CustomerName and CustomerId  parameters to get them into the parent form.

End Sub
