Where did I click in an Access list view

H Team

I want to allow users to modify values in a List View in Access.

I have a VB App that detects my mouse down location and places a text box over the list item I want to modify. I want to do this again but in Access. In VB in have to use Screen.TwipsPerPixcelX (and Y) to convert the mouse down coordinates to Pixcels. The trouble is that in Access I don't have the Screen.TwipsPerPixcelX properties. Does anyone know how to find out where I am when I click?

Thanks
