I need to pull hardware info and display into some type of a control like a ListView. I've been doing some general research and found that most people have used WMI. I would like to avoid WMI if possible because of possible compatibility problems.However, if that's the best way, then that's the way I'll go.I was wondering if anyone knew of other methods, perhaps an API or other unmanaged code?
View 3 RepliesI'm working on a base class right now, here's a basic rundown of it:[code]The problem is, in the Public Class bar example, some classes may implement MyInterface, and others don't. What I'd like to be able to do is have the sub New() in the structure in the base class "Foo" be able to tell if the class calling it (either the Base class, or the child class) implements MyInterface or not.
View 8 RepliesI was looking for some stuff online, and i was looking through my reference sheets for vb.net, but it seems in the code i have found, there is declare in methods. Below is an example i am talking about. The thing is, that i dont recognize it and believe that it is an earlier version of Visual Basic ( 6 or earlier) which used it. Should i just keep looking for different code?

View 3 RepliesI need to find a method of looping through a listbox and retrieving the index number and values - quite straightforward in asp, but turning out to be something of a nightmare in winforms!Here is the scenario - The user can add values in a textbox, that are in turn added to a DataTable that gives it a unique ID and a row number, this is then bound to the listbox. The user can then move the items up or down the list by adjusting the row number in the datatable and rebinding to the listbox..
The problem that I am hitting is when the user needs to delete an item -the first part is easy - delete from the DataTable and rebind to the listbox. The bit where I hit the proverbial brick wall is needing to loop through the listbox rows and getting both the index number and the ValueMember - that way I can change the row numbers in the DataTable based on the index number against the ID number.

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")

Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)

It gives me alot of information that I dont need, I know that I can use:

When I try the program on my own system there is no problem. But the customers said that everytime they start the program the messagebox popups and they have to choose the path again and again.
