How to get the Current Price of a commodity like crude oil,gold,silver in string edit field in an form.

For example if I choose 22k option in Combo Box the current price related to the gold should be retrieved from internet or any url related to commodity pricing.

Method name->modified for combobox.

Can anyone help me to Figure out exact solution.

It depends what data source you want to use. The usual approach is calling a web service providing the data, although you may also get a file to import, extract data from an HTML table or who know what.

Thank you
I will see to it.
