query a xml file and show results in windows form

Apr 27th, 2009

Hi all I am trying to make a little program that when you type in a number (anydigit) it will search the xml file and display the results in a text box, i have found some code that i would like to modify, the code here has no option to type into but a drop down box. How do I make it so I have to type the number in then click search ?
