Hi Antonio,


Thanks for your answer, but I think you didn`t understand my question.

Browsing an array is not causing me any problem for now.

What I want to do is use a COMBOBOX and combine two fields for selection in the drop down list. TestArr2.prg demonstrated how to browse multi dimension array.

Regards,

Gilbert

Hi Detlef,

Thanks for your suggestion. That`s exactly the technique I`m using right now, but I don`t like it. I was thinking of eliminate the second array and work with the original array instead.

The original multi dimension array content has to change according to two other Get fields. Working with two array makes the code much more complex because I will need to update the orignal array wich in turn will be used to update the second array.

Gilbert, I think you must do changes in TComboBox class to let this feature...
