hi,
I am now working in a project which has the following environment.
OS : windows 2000 server
Platform : .net 1.1
language : vc++.net
currently this project is in vc++ 6.0 (rpc server) and a vb 6.0 (rpc client) app will communicate to this thru rpc calls. now i have successfully (of course after having MANY number of errors) compiled it into VC++.NET. for some reasons, the vb 6.0 app will remain as it is.
my problem is , i cannot make vb 6.0 app to communicate vc++.net application IN ALL OF MY MACHINES. in one machine, i can run the project successfully. but when i copy all them , register all components into another computer, it won't run. when the vb app communicates vc++.net component, it stops saying "NULL reference pointer was passed to stub...". i cannot find ANY USEFUL information both in msdn and other sites. Can any genius help me regarding this if those genius come from VC++ team, i will really be happy about that.
regards,
ganesh.p
1780 null reference pointer was passed to stub - is there really anyway to get rid of this????

The problem you appearing to describe is a VC++ and VB6 issue. So the issue you describe (vb6.0 and vc++ 6.0 project) appears to be a solution based upon technologies pre-dating the .NET framework.
These forums are for VB.NET and there are better places to find answers for older versions of VB such as VB6 which are frequented by users of the VB6 product.
Maybe the VB6 newgroups - http://msdn.microsoft.com/newsgroups/default.aspx dg=microsoft.public.vb.general.discussion&lang=en&cr=US
or web sites such as www.vbcity.com
or maybe even the guys at the VC++ forums (although these forums tend to be for the .net products as well but if your solution was working in VC++6.0 and not VC.net they may be able to assist in providing some more guidance as the what may need to be configured as far as the VC++ component being able to be visible to a COM based project - such as VB6).

Hope this points you in the right direction.
