No such interface supported

[admin28Participant]

Running into the error message below trying to query customers. I’m using .NET/C# targeted to x86.

Here is the code I’m using:

var customerCount = qb.Company.Customers.GetActive();

List<CoreObjX80.Customer> customers = new List<CoreObjX80.Customer>();
foreach (CoreObjX80.Customer customer in _conn.Company.Customers)
{
customers.Add(customer);
}

Here is the full error message:

“Unable to cast COM object of type ‘System.__ComObject’ to interface type ‘CoreObjX80.Customer’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{D55C6A4E-85B4-48EA-8D8B-4EE71B34E4C7}’ failed due to the following error: No such interface supported (0x80004002 (E_NOINTERFACE)).”

So I sidegraded to a different version of the CoreObjX80.dll (I believe the one included in the OpenSync 3.0.28 installation, but I will have to check) and I can now do the above loop through the Company.Customers collection.

Hopefully this is the last major roadblock I have to making this work.

Yudel, I understand that completely.

But the issues I’ve been having are not code related, they were (it seems) installation related or DLL related.

try to unregister and register the dll. something that works.
