Hi,

Welcome to our Microsoft Q&A platform!

You can try to add a space like this:

object findStr3 = "No ";

Thanks.

Answer 2

Maybe execute ‘fileOpen.Selection.Find.MatchWholeWord = True’ before starting the loops.

But I tried "No ",it works well.Please see my code:

 private void Button_Click(object sender, RoutedEventArgs e)  
            {  
                 
                MSWord.Application wordApp = new MSWord.Application();  
                MSWord.Document wordDoc;         
                wordApp = new MSWord.Application();   
                wordApp.Visible = false;  
                Object Nothing = Missing.Value;  
                wordDoc = wordApp.Documents.Open(Environment.CurrentDirectory + "\\test.docx", ref Nothing, ref Nothing, ref Nothing, ref Nothing);  
                //object findStr1 = "Not Applicable";  
                //object findStr2 = "N/A";  
                object findStr3 = "No ";  
      
                //while (wordApp.Selection.Find.Execute(ref findStr1))  
                //{  
                //    wordApp.Selection.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdDarkRed;  
      
                //}  
      
                //wordApp.Selection.Start = 0;  
                //while (wordApp.Selection.Find.Execute(ref findStr2))  
                //{  
      
                //    wordApp.Selection.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdBlack;  
      
                //}  
      
                //wordApp.Selection.Start = 0;  
                //wordApp.Selection.Find.MatchWholeWord = true;  
                while (wordApp.Selection.Find.Execute(ref findStr3))  
                {  
                      
                    wordApp.Selection.Font.ColorIndex = Microsoft.Office.Interop.Word.WdColorIndex.wdRed;  
                }  
      
                wordDoc.Save();  
                wordDoc.Close(false, Nothing, Nothing);  
                wordApp.Quit(false, false, false);  
      
            }  
  

Thanks.
