Project works on dev machine only

[Tim Zych]

Stumped here.

When I access a ComClass enabled library in Excel on the development
machine, it works fine. When I install the app on another machine, and try
to access it, I get an error:

"File or assembly name DotNetApp, or one of its dependencies, was not
found."

I have a Class Library vb.net solution. It uses ComClass method to make it
accessible from a COM application (Excel). The "register for COM interop" is
checked. It also uses a 3rd party control. After I install the app, I can
see the 3rd party DLLs as well as the DotNetApp.DLL and DotNetApp.TLB in the
destination directory.

An Excel macro instantiates the class and shows a form. When I run this from
the development machine, it works fine.

When I install it onto another machine and try to instantiate the class, it
errors.

Dim c As DotNetApp.ClassName
Set c= New DotNetApp.ClassName ' ERROR
The 2nd line produces an error:

"File or assembly name DotNetApp, or one of its dependencies, was not
found."

What am I not doing, or doing wrong?

You do have Excel on the other machine right?

Thanks,

Yes, the other machines have Excel (I have tried this on 3 diff
machines..same problem) I can see the reference in Excel's VBE, and can Dim
a variable to the vb.net class. I just can proceed with the 2nd line.

As far as I can tell, the environments are similar. Same versions of Excel,
same versions of the Framework.

Did you register your comclass with Regasm or did you used a installer
module with the com flag on to install your custom com class on the target
machine ?
cause the IDE will do this automaticly for you

That really doesn't answer the question. When you copy to the other machine,
you need to run a command in a dos window (regsvr32 mycode.dll) or use an
installer system which does this. Did you do either of these steps?

Sorry, that should have said regasm, not regsvr32...

I used a setup program, which created an MSI file.

well it might be an idea to try it while manually registring the COM class
with Regasm.exe
http://msdn2.microsoft.com/en-us/lib...w6(VS.71).aspx

Maybe it shows an error that it can`t register on the target systems for
whatever reasson

also note the following :

A COM creatable class must have a public sub new with no parameters even if
you do not need initializers in that case provide an empty method

Public sub New()
'--- For COM
End sub
