VB 6 COM with .NET

2 New Member
Hi all,
I have problem with connecting VB 6 COM application/dll with .NET.
First of all, I wanted to create an application which will deal with bidirectional printer. I did it in VB 6 using some functions operating on "kernel32". But now I can't move it to .NET, as some part of code aren't upgradable.
I changed BV code to ActiveX DLL, but it is not working, as DLL isn't compiled, and .NET is first trying to translate it to it's platform, and the problem is the same like with upgrade to .NET.

So, what can I do, what can I create, that .NET won't try to upgrade it, but will communicate with C# ??

Hi Rafu,
Welcome to TSDN :)
I hope you like it here.

Have you tried referencing the VB6 COM DLL in your .NET code yet?
.NET has this Interop functionality that allows you to use COM objects in your code. When you reference the object in your C# project it should be able to use it properly thanks to this Interop technology.

Hi, thanks for reply.

Yes yes, I added reference, I see the namespace, methods, I can call them. But they don't work due to VB 6 objects, funtions, etc. And I don't know what to do now :/

Could you be a bit more descriptive in how they aren't working?
Seems kind of strange to me.

What error messages are you getting?
Are you sure the DLL is installed properly?
