dotnet interop: Can someone please help? I have verylittle time to coirerct this issue:

Someone gave me the following .files compiled with Visual Studio 2005 from a
..NET library compiled with COM Interop.

Roberto2.tlb
Roberto2.dll

Not sure what I'm doing...On my PC, I executed these statements:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regtlibv12.exe
C:\Roberto\Roberto2.tlb
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\regasm.exe
C:\Roberto\Roberto2.dll

I then ran this from VB6

Private Sub Form_Load()
Dim Test
Set Test = CreateObject("Roberto2.Test")
End Sub

It died on the Create object with the following error:

Automation error
The system cannot find the file specified.

Hi everyone!

I'm having the same type of issues as Chad...

I'm trying to use my CLA_Logging.dll (VB.net 2005) in VB6. I have used the
following to create a type library...

tlbexp cla_logging.dll /nologo /silent /verbose
tlbexp cla_logging.dll /nologo /verbose

Both times the cla_logging.tlb file was created. (only 2k in size ???)

I have also tryed to do a regsvr32 cla_logging.tlb and this did not work. So
I tryed reg assembly tool...

regasm cla_logging /tlb:cla_logging.tlb

This to looks like it worked. However, when I reference the cla_logging.tlb
in VB6 the cla_logging object shows up in the object browser but I don't see
any of the public properties or methods of my class library.

What do I need to do to get this to work?

TIA! JerryM

Hi

If either you or Chad figure out whats need to be done to get this work
please write the answer to the news group. I am trying having the same
problem with my dll file.

Hi

Solved my problem.

1. Added strong key to my in project
2. Build the .dll file
3. used registered the .dll with regasm.exe myClass.dll
/tbl:myClass.tbl
4. Added the .dll file to Global assembly cache (in my
c:\windows\assembly)

After that it worked fine with my vb5 project

Here are few good tips on .NET interop with vb6

Hello! It is not necessary to add a strong name and add it to the global
assembly cache, though this works well.

Here is an alternate approach:
1. Build the dll
2. Use regasm from visual studio command prompt: regasm.exe
c:\code\mycomponent.dll /tlb: mycomponent.tlb.
Using the tlb option enables early binding.
3. Place the mycomponent.dll in the same directory as your executing
assembly (your COM-assembly). This might be C:\Program Files\Microsoft
Visual Studio\VB98 if your using VB6 or C:\Program Files\Microsoft
Office\Office if you are using Excel.
4. Reference the component in your application
5. Write code for using your component.

Hi

I tested this but it did not work on my vb5 application without the
strong name and gac. Not sure why
