This handler adds a custom QueryInfo tip for: *.pas *.txt *.ini *.dfm Files. Run the Register batch file and run explorer browse to this file type and hover the mouse over the file (assuming Info Tips are turned on in Explorer). To unregister run the UnRegister batch file. To Minimize the size of the DLL open the: {EasyNSE}\Include\EasyIncludeHandler.inc file and uncomment out {$DEFINE NO_PROPERTYSHEETHANDLER} and {$DEFINE NO_MENUHANDLERS} Define. This will remove the PropertySheet and Context Menu handlers from the build and the Forms unit will be excluded from the DLL.
