EmailAddressTo = lstbxEmailAddress.SelectedValue.ToString()
MessageBox.Show("To Address is ", EmailAddressTo)
When I run this, in my message box, I get -
"System.Data.DatarowView" as the title of my message box "To Address is " And when hit F8 to continue debugging I get the ff error msg - "The specified string is not in the form required for an e-mail address."
i am new to dot net and i have a problem with this code below. what is expected is that the method should add the names in the string in random order into the listbox. but the output shows only single alphabets added rather than the whole name. i don't know where im wrong.can anyone correct me?

If I set a ListBox.Height = ListBox.PreferredHeight when the control is hidden and IntegralHeight = True, then set it visible:
a) Actual Height reduces by typically 3-5 pixels after redraw (but not 1 pixel per item).
b) PreferredHeight does not not appear to give the correct integral of item heights.
Is there a way to make ListBox calculate the correct integral Height before the ListBox is made visible, so it can be correctly pre-positioned from bottom edge?

It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]

I 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.
View 5 RepliesThe scrollbar that comes with the ListBox is too small for touch screens, so I use my own scrollbar instead. But when you do this on various forms you end up repeating a lot of code. So my solution was to create a custom scollbar that has a property I can set to the control I want it to be a scrollbar for. In vb6, I can use the withevents keyword to get access to the control's events so that all the scrollbar related code can be in the custom scrollbar object I created, except...I had to create a refresh method for the consuming code to use to let the scrollbar know when the number of items changes. The scrollbar doesn't need to be told how many items there are because it has access to the control, but for a listbox there is no event to tie into when an item is added/removed so not 100% of the scrollbar related code could be encapsulated.

I am using Visual Basic 2008 Express Edition and I am trying to set a listbox so it starts to scroll when it hits the middle point of what is viewable on my list. I also want to set it so the list is always visible so you when you reach the bottom of the list you can scroll down to the bottom but if you scroll back up once it reaches that middle point it will start to scroll up again.

I am having problems with copying from one listbox to another and keeping the paths of the files in the listbox's. At the moment i have two listbox's, listbox1 shows the list of files without the directory paths showing. Listbox2 is used to add items from listbox1 which work ok but what i need is to be able to preserve the directory paths to each file. how to do this and have searched high and low for a solution without any luck.
I have worked out one way of doing it but i think there is a better way of doing it as the reverse does not seem to work. So basicly i want listbox1 to list the files without the paths and pass it on to listbox2 so that the files can be copied to temp directory as they are being add to listbox2.
Below is my
