QTP/UFT tip: Using OTA in UFT API test shows "Could not load type 'TDAPIOLELib.ITDConnection6'

[vzamoraz]

Using “TDAPIOLELib.TDConnection qcConn = new TDAPIOLELib.TDConnection()” from OTA (Open Test Architecture) Library in UFT 11.5 API test, this error message appears: "Could not load type 'TDAPIOLELib.ITDConnection6' from assembly 'Interop.TDAPIOLELib, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."

However if this is used in Service Test (ST) 11.2 the command works properly.

Cause:

The error occurs because of the version of .net framework, on UFT API test the framework is .net 4.0 and in ST is 3.5, so the Interoperability fails.

Solution:

In order to use a OTA connection that works properly in UFT APItest use this comand to start a conection:

TDConnectionClass qcConn = new TDConnectionClass();
