at runtime write-protected properties do not occure at self-built controls

Hallo,
I built an own activeX control to add additional properties to the textbox control.
But did anybody of you notice that ALL properties (of the textbox) that are write-protected at runtime do NOT appear in the properties list of my new control? So you cannot use this property anymore.
It is very strange!

E.g. in my case the property 'Multiline' is not shown.
And if I try to add the specific code manually, e.g. with:
Text1.MultiLine = New_MultiLine

Then the compiler throws out the error:
"Assignment to a write-protected property not possible". Strange because this equation should be possible - at design mode!!!

Or does maybe anybody know where the write-protection information is saved (so that I could deactivate it)?

Hope that anybody can explain what is going on here!?
Thank you very much.

Many greetings

When you create an ActiveX control based on a constituent control the ActiveX control doesn't automatically inherit all the properties, methods and events of the constituent control. You have to map this yourself. Luckily VB has an add-in that makes that easier. It can be found on the add-in menu and is called "VB 6 ActiveX Ctrl Interface Wizard".

oh, I did all of that already, don't mind!
(unfortunatelly the add-in does not offer for constituent controls the option: overtake all options (prop., meth., events). Never mind)

And for the property Multiline the generator did not even create a let function !!
When I do that manually (adding a let function - as I described at last) like:
Text1.MultiLine = New_MultiLine
an error is returned.
I described that at last.

So maybe you know now what I mean?...

We would know alot better if you showed the code you have right now

I have shortened the code to the most important.
Here it is:

****************************************

The two lines that do not work I marked with 'Problem!'.
Does this help you?...

now did you check the code?
Do you understand the problem now?...

But I am afraid this problem cannot be solved!?
My explanation: building own apps on top of existing (constituent c.) is dependant from the 'outside' parameter interface (properties, methods, events) of them.
And this one does not seem to distinguish between design and run mode but only offers parameters of the run mode.
Right?
I cannot find another conclusion.

What do you think?....
