I also wonder if an ActiveX control might offer more access.

>>For controls which display one row of data, such as a text or combo, you have the control's location. You can use the control's .SelStart property to find out the character position of the cursor, extract the characters up to that point. A combination of TXTWIDTH() (returning the length in characters) and FONTMETRIC(6) (returning the length in pixels) to get a very close approximation.

>>I don't know of a way of determining exactly what row and column position a cursor resides on in an edit box. You can calculate pretty close by using the control's size, and FontMetric. The length in pixels you can approximate with TXTWIDTH and FONTMETRIC (6). For the height you need to factor in the character size as well as regular and special leading (FONTMETRIC (1) + FONTMETRIC (4) + FONTMETRIC (5)).

>>Divide the text width in pixels by the control's width to get the integer line number. Line numbers times height gives the distance from the top of the control. The Mod of the text width dividec by the control's width can be used to provide a percentage of the width to locate your popup.
