VB and .NET Framework

[Fergus Cooney]

Hi Howard,

You say you have it in VB.NET - what are we supposed to do with this VB6
code?

Regards,
Fergus

In order to determine whether my sister could run VB or VB .NET on her
recently installed system, I created a VB 6 app, and corresponding VB .NET
2002 and VB .NET 2003 versions.

The VB 6 code is given below.
Code is just simple API and WMI calls.
I do not want to convert the calls to Framework calls.
All I did was import the .vbp into both versions of VB .NET and build each
..exe.
I want to use the upgraded code without doing a full conversion to VB ..NET.


I sent her all 3 .exe files. Al three .exe files work on my system.
I have .NET 2002 and .NET 2003 installed in separate OS.

She was able to run the VB 6 version.

Note that she does not have VS .NET, but she tells me that she installed
..NET Framework 1.1 using Windows Update.
As expected, the VB .NET 2002 .exe would not work.

However, when she ran the VB .NET 2003 .exe, she got the following message:

WMIvb2003.exe - Common Language Runtime Debugging Services

Application has generated an exception that could not be handled.
Process id=0x538(1336), Thread id=0x150(336).

Is this a problem on her system, or do I need to do something more when
creating the .exe?

Which operating system is your sister running?

See the WMIvb6.zip at http://www.standards.com/index.html#Temporary.
The .vbp project file can be opened in VB 6 or VB .NET.

I am following up on this discussion in a topic "Is
Microsoft.VisualBasic.Compatibility Library installed by .NET Framework?" in
the microsoft.public.dotnet.framework nesgroup because I believe that the
problem is a Framework, not a VB issue.

I posted a simpler example in that thread.
