Add-In creates ListBox from XLS, but data not saved in ppt

[barbet]

Hi ppl,



I created a cool VBA Add-in for ppt which allows me to select a XLS file and then takes the data from the first sheet and puts it nicely in a ListBox (using a custom button in the menu).

I'm really happy how it works, however, upon saving de ppt, the content of the ListBox isn't saved. This is a pitty, cause now I have to load the data manually every time I want to use the ppt.

Who has a solution for me!? I'm using PowerPoint 2010. The data is extracted from the XLS and stored in an array. The array is assigned to a newly created ListBox on the selected ppt sheet.

Thanks very much in advance
