hallo,

i have a big problem with an activex control and a type struct.
i want to store some values in a type struct in the activex control.
the values must be known and changeable in the property form and
from external. i´ve tried it with class and module. internal with friend, external with public functions or properties.
no success.
how can i do this.

here is a graphic.

                 |-----------|
                 | Property  |
                 |   Form      |
                 |              |
                 |           |
                 |-----------|
                     /\
                     ||
                     ||
                     ||--->< values in type-end type struct
                     ||
                     ||
                     \/
                 |-----------|
                 |  ActiveX  |
 Public     |  Control    |
 values><|             |
                 |           |
                 |-----------|

thank you !

Split the struct into its various fields for the purposes of sending the data back and forward from the control.  Then reconstruct the struct inside the control once it has received all of its property values.

Do you mean this:
Public Type str
a As String
b As String
End Type
Dim o As str

Public Function test() As str
o.a = "abc"
test = o
End Function

Private Sub UserControl_Initialize()

End Sub

This should work.
Be carefull,there is a bug fixed with SP3: http://support.microsoft.com/default.aspx?scid=kb;EN-US;q223116

Link Public Variable through the Property Get, Set and Let.
EG:
In Module declaration:
Private Type MyDataType
  MyString as string
  ANumber as long
  MoreData as String
End Type

Public MyData as MyDataType

In the class section use:
Public Property Get MyString() As String
    MyString = MyData.MyString
End Property

Public Property Let MyString(byval vData as string)
    MyData.MyString = vdata
End Property

etc.
