Taking Picture of a control/window with expanded combo box

Hi all,

i was writing a test where i need to take a screenshot of the window and save it to disk.

It works well except that in the screenshot im taking, i have an expander combobox where i can see all the items listed in there.

I would like to include this inside my screenshot, however when i do my TheWindow.Picture() it closes the combobox when taking the screenshot.

I was wondering how i can ensure that the screenshot includes this expanded combobox.

During the playback of tests, i see that TestComplete is able to take screenshot of controls and there expanded lists, so im guessing it must be possible?

Thank you for any help!

  • Not sure if it makes a difference but it is for a Desktop application and not a web.

    I managed to make it work (not perfectly) using Desktop.Picture and using the control bounds.

    Here is the script i use:

    function takeScreenshotAndSave(control, folderPath, fileName) {
        try {
            // Validate the input parameters to ensure they are not undefined or null
            if (!control || !folderPath || !fileName) {
                throw new Error("Control or file path or file path is undefined.");
            }
            
            // Take a screenshot of the control. The Picture() method captures the control's current visual state.
            var picture = Sys.Desktop.Picture(control.Left,control.Top,control.Width,control.Height,false);
             //control.Picture(control.Left,control.Top,control.Width,control.Height,false);
            var fullPath =folderPath + "\\" + fileName;
            
            IOOperations.CreateFolderIfDoesntExist(folderPath);
            
             // Save the captured image to the specified file path.
            // The SaveToFile method takes the full path, including the file name and extension, as its argument.
            if (picture.SaveToFile(fullPath)){
              
            // Log a message indicating the screenshot was saved successfully.
            // This is useful for debugging and confirmation purposes.
            Log.Message("Screenshot saved successfully to: " + fullPath);
            
            }
          else
            Log.Error("Could not create the picture " + fullPath);
                   
          
        } catch (e) {
            // Handle any errors that occur during the screenshot capture or file saving process.
            // This block logs the error message, which aids in troubleshooting.
            Log.Error("An error occurred while taking a screenshot: " + e.message);
            
            // If needed, rethrow the exception to handle it further up the call stack.
            // Uncomment the line below to rethrow the error.
            // throw e;
        }
    }

    However if i use the commented line #10 instead of 9, the dropdown is closed. 

    It would be nice if there was an option to prevent that.

    If the control looks likes this, and no other items are shown in the Object Browser, then I don't think it's possible. As it's the browser that draws the UI.

    Other controls such as Bootstrap, you can capture the items of the dropdown

      What you have, is probably the best method.

      Like the web behaviour, doing list.Picture, also closes the drop down list and only captures the combo box.
