checkedlistbox

问题 I'm using a CheckedListBox control in a small application I'm working on. It's a nice control, but one thing bothers me; I can't set a property so that it only checks the item when I actually check the checkbox. What's the best way to overcome this? I've been thinking about getting the position of the mouseclick, relative from the left side of the checkbox. Which works partly, but if I would click on an empty space, close enough to the left the current selected item would still be checked.

问题 I'm having trouble with multiple issues with a checkedlistbox. Its content is the Windows feature name (commandline parameter to install a Windows feature via Powershell) and a description which really is its more readable name. Because I develop on Windows 7 and this command is only available on a Server platform I read the data from a XML file source. The XML file was created by the output of function BuildFeaturesFile, below. I've pasted a sample at the bottom if that is a problem. 1) I
