I made a Windows application using C#. WinApp consist a ListBox control with a large catalogue items. When you type some letter a ListBox control select a first item in catalogue with chosen first letter in some item name. Because a catalogue have many items with the same first letter in item name I want that any second letter you type treat as a next letter in a name of item, not as a first letter of some other catalogue item. Can somebody give me idea how to programming a ListBox control to do that? I think that I was formulating a question well. Thanks.

I've had to go through this before too. I'm not sure about the C# calls and event names, but in VB it was the keypress event that did the trick. Just get the time of the keypress at the beginning of the command. Compare this to a form level variable you saved the last time a key was pressed. If the strokes occur fast enough, concatenate them to another form level variable, otherwise make the reinitialize it to the key that was pressed. Use this string to find the next one with a greater list index than the one currently selected. Hope this helps.
