Listbox Items Colour - Two Types Of Items Populating In A Listbox (checked Listbox)
Apr 28, 2009I am using VB.NET (version 2008). I have two types of items populating in a listbox (checked listbox). For example: lets say one is type "A" and other is "Type B". Their names maybe same so if the user sees those items in listbox then he won;t be able to determine their type until he click on them and checks out its properties. I wanted that I add each item to listbox and colour them so that blue for example means type "A" is there and red means the other. So this way I will be able to know at a glance that how many item of what type is present. I guess it may not be possible to do that in a standard checkedlistbox. I am also using component factory's krypton controls which enhance the gui of an application. But I dunno if I can progress using that.

Directory Items TO Listbox Items?
Mar 17, 2009I'm making an application that does some stuff involving the given subject, so this is very crucial to the completion and efficiency of my application.What I'm in need of today is simple (well, "seems" simple). I have one listbox that I want to populate with directories file's names. I don't mean the files inside the directories, but the names of the folders inside the directory.So, I have "c:empdog", I'd click on my button or whatever and search for the directory and I choose "temp", said listbox would show "dog".
UPDATE: Oh, BTW. It doesn't HAVE to be a listbox, it can be anything (IE: Textbox, Labels, Etc.).

Nov 4, 2010The following image or RTF file illustrates how I'm trying to transform an input Byte array into an output array of Booleans. This is basically what I have listed below. figure out how to get from one array to the next while shifting values of bytes within 8 byte groupings to shift low order to high order or vica versa. What I mean by that is best seen by looking at the illustration of actual input an required output. The reason for this is that the hardware devices have registers and the display which can be seen in the links above needs to convey the disabled sensor cable cell locations.

Program That Will Compare Array Of Grocery List Items Glist And Array Of Coupon Item List
May 27, 2012I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
