Hello, I have the GUI where I am populating various MS Excel spreadsheet names in a ring dropdown control, also reading the spreadsheet on selection in the ring control and displaying in a multicolumn list box. On the backend, I am using the event based code; using a cluster and rotating this data in cluster using a shift register, also initializing this shift register. Now, I want this selected data (spreadsheet names in ring control, spreadsheet data in multicolumn list box) to be available when I open the tool next time. What would be the options to save this history? I could do this by not initializing the shift register BUT I don’t want to do this way because I have some other data in the cluster which needs the initialization. What is the typical/standard method to save the history? Do I need to maintain a configuration file so anything like that? Please suggest. Thanks.
