method Edit.AddWild (Expression as String)
Adds a wild characters expression to a sensitive control.

TypeDescription
Expression as String A string expression that specifies the HTML format for a wild characters expression. The wild characters supported are '*' and '?'. Also the wild expression supports escaped characters, AddWild("<b>\*") bolds the * character only, not including the rest of the line, while AddWild("<b>\**") bolds everything after a * character.
The AddWild method adds an expression that may contain wild characters like '*' or '?'. Use the FormatNumbers property to specify the format of the numbers in the control. Use the AddKeyword method to add new keywords to the control. Use the AddExpression method to add new expressions to the control.

The following VB sample shows in bold all till : character, shows in gray till ; and let the rest unchanged: 

With Edit1
        .AddWild "<b>*</b>:*"
        .AddWild "<b>*</b>;<fgcolor=808080>*</fgcolor>:*"
End With

End With

If you want to highlight only the part between '<' and '>' then you should use a sample like follows:

With Edit1
        .AddExpression "<", "<b> </b>", ">"
End With
