DBCOMBO question to James

Posted: Fri Nov 16, 2007 02:09 PM

James

What would be the reason a dbcombo would show the "relative" position in the file for a numeric item instead of the real value ?

The combobox is redefined from resource and is not defined "sorted'

Thanks for help,

Richard

Richard,

You can't use numeric data with either Combobox or DBComobo--the data must be converted to string. If numeric data values are passed as parameters to methods then they are assumed to be locations, not data elements.

DBCombo inherits from the Combobox class so it inherits the same behavior. Some time ago I tried to modify DBCombo to handle numeric data but it turned out to a huge amount of work since I would have to rewrite most of the combobox methods too.

Since DBCombo's can also use arrays, then you can just convert the database info to an array of strings before initializing DBCombo, then convert the selected value back to a number.

Regards,
James
