problem to load the dll

[john4TMYX]

Hi guys,

We have a com object which is used to register in the pc so the Inventor will pick it up. But now we need to use the addin file. I have converted the dll into the register-free dll and add a addin file to the Inventor. Now the Inventor can pick the addin file, but can't load our dll. What I want to know is that whether Inventor can print some error message so I could trace the issue. I  have compared the file with the sample file loftWithRailling, I didn't see much difference. I have also checked the compiler options, it is same as the sample project.

Can anyone please shows me how to get the error message from Inventor when it fails to load the dll?

I have changed the guid for the dll.

Use messageboxes in each step of the code!

Hi guys,

I have found that there is problem to load the dll:

STDAPI DllGetClassObject (REFCLSID rclsid, REFIID riid, LPVOID *ppv)
{
AFX_MANAGE_STATE (AfxGetStaticModuleState ()) ;
if ( _AtlModule.GetClassObject (rclsid, riid, ppv) == S_OK )
return S_OK ;
AfxMessageBox(_T("something is wrong in DllGetClassObject"));
return AfxDllGetClassObject (rclsid, riid, ppv) ;
}

so if it is ok, then it should return S_OK, but my program always end up to run the AfxMessageBox, could anyone please show me where I should go? Is it the server class can't be created? Why the program runs ok when registering the COM object? InitInstance () works fine as the init function return S_OK.

Thank you.

Regards

Eric

Hi guys,

thank you for help, my mistake is that I use the lib guid. I should use the class guid.
