There was very interest and original work: to make the universal add-in for MS Word 2000, 2002, 2003, 2007. After add-in was installed each time the user enters the word “gobo” – it automatically replaced by the image with the GOBO logotip.
The program written many times, first in MS .NET 2008, then in .NET 2005. But the add-ins was incompatible between different version of MS Word. So the final variant was written in Visual Basic 6.0.
