'A2:A10000'); set(handles.listbox1,'UserData',substance); I noticed that cells were under UserData in the Property Inspector so I tried changing 'string' to 'userdata', but no dice. It doesn't work with string either. Also tried both with cell and char. Same result...

But that doesn't really help me solve my dilemna....I use set in other places in my code with handles and it works fine. So how do I set a listbox? > Thank you for your input. ---------------------------------------------------------------------------------------------------------------------------------------------- I believe a listbox can only take an N rows by 1 column cell array. Do you get this shape of cell array when you read in your Excel file? It will probably fail if your data is not in one single column in your spreadsheet.

Hmmm. My array is just a list of pharmaceutical agents with one column. In Property Inspector you can set the number of columns and rows under UserData cell. I tried changing it off the default (1x0) but it didn't work. This doesn't seem too difficult, but of course its proving to be. Are there settings in Property Inspector or guide that I might be overlooking?

So I converted it to a structure and read them into the listbox with a for loop. Debugging in progress. Anyone wanna test my theory with me feel free...

I suggest you put a breakpoint in at the set() line, and examine the value of handles to see whether it is what is you expect. |
