The sample form demonstrates how to check the spelling of text in a Uniface Edit Box using the Spellchecker of Microsoft Office Word 2013 (through the COM call-out interface). It is also shows how to avoid that the Spellchecker window is shown behind the Uniface application window (by temporarily making the Uniface application window the parent window of the Spellchecker Window -i.e. the Word application window). For details about this problem see the following post: http://unifaceinfo.com/forum/uniface9/looking-to-for-a-good-spell-checker-dll-to-call-from-a-uniface-app. Simply import and compile all (sample form, COM and C call-out signatures).
