Hello

I have a problem with .Net control events . To my WinCC project I have to write custom .Net controls. I used Visual Studio 2010 Proffesional. My controls have events to return specific informations to WinCC.
Below C# code for my events:
definition of delegate: [code]public delegate void Blad(string tytul, string opis);
[/code]
definition of event: [code]public event Common.Blad WystapilBlad[/code]
So as you can see when event is executed inside control it exposes two parameters with some data back to WinCC.

First I tested my controls in WinCC 7.0 Proffesional with this system: Windows XP 32bit SP3. When I placed control on screen I select Properties->Events->Object Events. Next I select control's event -> WystapilBlad. I choose VBS action and WinCC generates this code:
[code]Sub WystapilBlad(Byval Item, Byval tytul, Byval opis)
End Sub[/code]

Which is what I exactly want. I can use data returned with these 2 parameters: 'tytul' and 'opis'.

Next it turns out that we won't use this version (WinCC 7.0) but this one: Tia Portal V11 SP2 .
And Windows version is Windows 7 Ultimate 64-bit SP1.
So I had to check if everything is OK with my .Net controls.

As before I place my control on screen. I selectt Events tab and on the list I see my event: WystapilBlad. Next I select VB function and this code is generated:

[code] Sub OnWystapilBlad(ByVal item)

End Sub[/code]
There isn't any parameters except 'item'. Parameters 'tytul' and 'opis' is not here and I don't know why. Can anyonetell me what is wrong. I really must be able to use my control events as it works in WinCC 7.0.
I am new in Tia so maybe I am missing something.

I included source code of control (in VS 2010) and dll control itself.
The project in both cases was compiled for .Net Framework 2.0 (with configuration for Any CPU) so it shouldn't be problem 32 vs 64bit.
I also tried to compile both 32 and 64 bit but with no difference - problem still exists.

I'll be appreciated for any advice with my problem.

regards!
