Hi Suneel,
First of all, please make sure that your tested application is compiled with debug information - this will make TestComplete recognize the application properly. Refer to the
"Preparing Delphi Applications for Testing" article to learn the exact steps you need to perform based on your IDE version.
As for the TMS controls, TestComplete officially supports some controls of this vendor. You can find the list of them in the
"Supported TMS Controls" article. If the controls used in your app aren't on the list, I can suggest two options:
1. Check whether the controls are inherited from the supported controls. If they are, use the
"Object Mapping" feature to make TestComplete treat the controls as the supported ones.
