In my program, I’m using Find.Execute to search for all the word forms of a keyword and highlight them. For example, If my source document contains “perform” and “performance”, Find.Execute(...matchAllWordForms=true...) will find both words, but it will only highlight the ‘perform’ section of performance.

How can I get MSWord to highlight the entire word? The range.Text is changed by Find.Execute to just be “perform”, so I cant iterate through that. I tried doing a Range.Select() and then iterating Selection.End, but the ranges do no match up with the original document.

Any help would be greatly appreciated!

    Well, I feel kind of stupid:

    I was trying to use Selection.Extend and completely missed the Selection.Expand option. For anyone who stumbles across this later:

    range.Select();    // The range after Find.Execute
wordApp.Selection.Expand(Word.WdUnits.wdWord);    // may have to trim off excess whitespace
Word.Range highlightRange = document.Range(wordApp.Selection.Start, wordApp.Selection.End);
wordApp.Selection.Shading.BackgroundPatternColor = (Word.WdColor)System.Drawing.ColorTranslator.ToOle(extractedColor);

    Note that I use Shading for my highlighter (so I can create custom colors with System.Drawing.Color.FromARGB(Alpha,R,G,B) instead of the default 15 colors).
