I'll take a look at the pictures but it might not help.
According to documentation (https://support.smartbear.com/testcomplete/docs/app-testing/desktop/power-builder/index.html) TestComplete can interact with PowerBuilder applications, but depending upon whether you're using PowerBuilder Classic or PowerBuilder .NET the methodology is different. Additionally, there are particular versions of both that TestComplete supports. So, if you're using a more recent version of PowerBuilder than 12.6 (which appears to be the most recent version) then you might have difficulties.
In any case, take a look at the documentation for preparing PowerBuilder applications for use with TestComplete. That would be the first place to start.
EDIT: Looking at the pictures you provided, you are definitely using PowerBuilder Classic and attempting to interact with components in a DataWindow. According to the documentation (https://support.smartbear.com/testcomplete/docs/app-testing/desktop/power-builder/classic.html#GeneralNotes), TestComplete cannot interact with DataWindow controls without using MSAA. Instructions are provided in the TestComplete documentation on what you need to do with your PowerBuilder application in order to allow TestComplete to access those components.
