Is there a way to make a listview select an item based on what a user types? for example, If i have a listview with a column (last name), and the Listview is in focus, I want the user to be able to start typing and have the row select move to the row that has the letters in that column

I simply want to have a list of all graphics saved in specified folder displayed as miniatures - this suppose to be a sort of an image browser - it does not have to be done using ListView, so I'm open to any suggestions.
I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

Well I had a thread going that branched out to this topic, so rather completely veering off the main topic there, I felt creating a new thread was adequate.So as the title says, I'm trying to create a user-defined type. It's not a simple type at that but a user here had showed me a way to fix all my problems. That was to create a type BigDecimal. Which my initial thought was to utilize the BigInteger type. Being that the Integer Part, and Fractional parts would be split off into two variables, both BigIntegers. Which would be combined at the end as a "decimal". However I have many many questions see that this is my first attempt at truly creating a type of my own. So as of right now I'm basically swinging in the dark here.

In a VB.NET Web Site, the User Types syntax coloring doesn't work. What are potential causes of this? It seems to not understand the difference between a "User Type" and an "Identifier."
Note: C# works as expected.
I need to be able to raise different types of audio notifications to the user. I need an "ok" and an "error" type sounds, I was hoping to be able to raise a simple beep and a critical stop type sound but I can only find the Beep() command which doesn't allow for differing sounds. Is there a library that does what I need or will I need to roll my own using the system wavs.
View 3 RepliesWithin the application, I need to have two levels of access: Standard User and Power User,for example.These two levels can have the same access level within Windows.It is not my intention to elevate to administratoWhat is needed, is a way to have two different groups of users.ne group will be able to run the application while a second group has access to additional features within the application but not within the windows environment
It is my hope that there will be two user account types: 1) Standard User and 2) some other user type such as Power User or something else that will distinguish it from Standard User

The OnChanged event should look at each line in the RichTextBox and if the line is of prime length colour it red, otherwise colour it black. How do I do this?

I'm currently attempting to use a .NET WebBrowser to display help information (stored locally in html files) for an application I'm writing, however I'm experiencing two problems, both related to hyperlinks.
Firstly, I have a search function which returns the correct URL in the format file:\C:... I can copy and paste it into a browser, and it will navigate there. Yet clicking on the link within the control itself does nothing at all.
Secondly, the HTML files all contain relative paths to other HTML files. These of course do not work as I just end up with file:\C:help.html which gives me a 'webpage is unavailable.' But I can't think of a way to get it to work without parsing the HTML file and concatenating the path to the directory on to the front of the link.
Just to clarify, in the first problem I am dynamically building a search result page as the user types. The HTML contains several results similar to this (yes, it's unfinished, I'm just showing you the link part): [code] Now, when I click on that link in the control nothing happens, it doesn't give me a 'webpage is unavailable' or take me to the actual page. Saving the HTML, however, and opening it with Chrome, IE and Firefox works fine.In the second problem, I have a different help file for different sections, each containing relative links to several others. VB picks these up as direct paths, and attempts to go there from root, i.e file:\C:file.html. The only solution I can think of is to parse the file and use WebBrowser.Navigate(Path.Combine(pathToDirectory, nameOfHelpFile.html), which seems a lot more inefficient than it should be.

View 1 RepliesI am writing a code-generator that will need to output some miniscule portions of VB.NET code, and since this is a code generator that will add user-provider code, I'd like to try to avoid type name conflicts with types or names in the user-provided code.
In C#, I can prefix types with global:: to make sure they're matched from the global type namespace hierarchy, rather than some local name, but is there a similar system for VB.NET? ie. this: global::System.String
I have an issue with Visual Studio's support for coloring User Types in VB.NET, I'm an C# developer that have been forced to code in Vb.NET by political rules in my organization, and I really misses the support for coloring user types in Vb.NET, I had hoped that this would be solved in Visual Studio 2010 and well in the beta they have added Vb.NET User Type coloring, but the coloring is the same for all user types I cant't have one color for interfaces and one for classes and so on.

I have a lengthy XML file that I want to search based on text that a user types in. Because it's lengthy, I want to wait for the user to stop typing for 250ms or so before I actually start searching in the background. I tried to kick off my Task, having it sleep for 250ms, then check if my CancelTokenSource had canceled because another character was typed. I'm not seeing a cancellation, though, so I end up seeing my results flash several times as the queued up search tasks complete, one after the other, after I finish typing.

I have a class with a Property called 'Value' which is of type Object.Value can be of any type, a structure, a class, an array, IList etc.My problem is with the setter and determining whether the value has changed or not.This is simple enough for value types, but reference types and lists present a problem.For a class, would you assume that the Equals method has been implemented correctly, or just assume that the value has changed every time the setter is called?If I did assume it's changed, then perhaps I should assume it for value types as well, so that the behaviour is consistent.
