My goal is to write an application that will be able to capture from another Microsoft application (e.g. MS Excel):

  • The picture of the application window - one picture per application window if there are more windows.
  • The picture of all icons when the mouse is hovered over the icons including the picture of the icons when the mouse is pressed.
  • The picture of the tooltip that will show next to the icon.
  • The picture of the mouse cursor if there is a specific cursor over an icon or over different areas of the application window.

What is the best practice?

Using UIA I can get all the coordinates of all icons on the window. Then I can set the mouse position over the icons and capture the icons one-by-one. The program will wait about two seconds over each icon to capture the tooltip of the icon. Then I can tell the user to click each icon and capture the picture of the pressed icons. At the end I will move the mouse over the whole application window and detect any changes in the mouse pointer. Is there any better way?

There is already a question about capturing the tooltips but with no solution: Get Win32 legacy control's tooltip text programmatically

  • So I can see you already did some workarounds and have started. Go on, implement the POC and post it here. If needed that can be optimized. – Souvik Ghosh Mar 08 '17 at 15:44
  • I have already implemented the process using an old MSAA library few years ago. Now I want to know if there is any different (faster) approach. – Vladimír Adamovský Mar 08 '17 at 16:07
