[Openroad-users] OpenROAD and .net COM

[Jonathan Barton]

Hi Colin

We had vb6 classes that are built into a dll and used by OpenROAD.  I
have now produced a dll using vb.net which can also be used by OpenROAD.
Be advised I have only gone as far as prototype, and it is not
production tested.

It was not straightforward (not for me anyway!) but I did finally get
there.  I had help;

The attached document was kindly provided by Neil Warnock.

I also used these links;

http://www.codeproject.com/vb/net/MusaExposingCOM.asp

The attached document provides all you need although I did use Visual
Studio .net to generate the dll and tlb and once I copied the 2 files
onto the destination PC I then ran the following commands;

C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>gacutil /i
c:\windows\system32\BusinessSystemsNET.dll
C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322>regasm
BusinessSystemsNET.dll /tlb: BusinessSystemsNet.tlb

If you would like a copy of some code let me know, but the links above
do show some simple examples.

HTH.

the same problem ....

Hi all,
 
We have been using COM objects written in VB6 in our OpenROAD apps for
quite a while, but I wanted to start taking advantage of some .net
functionality (plus most of us here develop using vb.net now not VB6).
 
I replicated some of our VB6 classes in .net and deployed the project -
trying both exe and msi.  Either way OpenROAD can see the classes that
are within the .net COM component but not the methods/functions within
them.  The Registry and Type Library look ok.
 
Does anyone have any experience with this?
 
Many thanks.

JONATHAN
