TestComplete.exe C:\code\Takeflight\TestProjectVinea\TestProject1.pjs /run /project:Calculator /test:Test1 /ExportSummary:"C:\code\Takeflight\TestProjectVinea\TestProject1\output\report.xml" Re: The combox can't select the item, how can i fix it? What is the actual error you are receiving? Also do you have multiple windows open with the same name? I have found this can cause some confusion and setting a name mapping value can resolve this issue. Re: Mouse click not proper I was able to solve this issue by using the page down key. In my example the grid value I needed to edit was at the bottom of the page. I paged down until the value was in view and then made the edit. This allowed the grid in view to have the exact same setup every time. Only problem with this is if the grid changes (values added or removed) you will need to update your script. Re: How do I simulate holding "UP" key I would think in a testing or automation sense you would not want to leave this to chance and input the exact number of times up is hit. Re: Does Testcomplete support to automate Slider in image options ? Have you tried using the page down button or using the Keys function to simulating the arrow key actions?
