Hello Sinchan, ComponentOne has the VSSpell 8 control, which is an ActiveX control designed for use in VB6. It has both dictionary and thesaurus functionality, and has a utility to allow you to edit the existing or create new dictionaries and thesauruses. For more information, please visit http://www.componentone.com/products.aspx?TabTypeID=1&ItemType=1&PanelIndex=16&ItemID=54015&SubCategoryTypeID=0&TabMapID=92&TabID=111[^]. If you think that you may be interested, you can download a fully functional trial. The trial will have a sample application to show you how to use the control to spell check a textbox, among other text sources.
