Hi Alex,
What exact version of the product are you using? Since TestComplete 7.0, our product has improved support for Delphi applications, and they are open for TC by default.
Please note that, in case your control is not on the list of the supported ones (the "
Working With Custom Controls" help topic), you need to include debug information in your application to get access to the application's internals (in addition to the fact that your application is already open to TC). Please see the "
Debug Info Agent" help topic.
If you still face some issues, please clarify the target controls' names, versions and vendors so we can provide you with corresponding suggestions.
