After 4 years, I must now expand and adapt an old program with new features for Windows 7.I use the great snippet from Chris to query the members of a active directory group.Now I want to use a selected item from the Listbox for a further search, but it doesn't work. I check the selction with a Textbox, but I get an error message:"Invalid Conversion from DirectoryEntry to String".[code]Until now I was able to read the selected items from the listbox in a Textbox or a query.
View 1 RepliesI am reading a txt file and displaying the contents into a listbox but it generates an empty listbox item at the bottom of the listbox. I am splitting the textfile each time it finds a new line in the txt file;
.Split(vbNewLine)
The problem there is always a blank line in the txt file at the end and so generates a blank list item. How can I remove this blank list item from the listbox? Is it best to try to remove the blank line from the txt file first or the empty list item from the listbox after the file has been read?

I already have a code for detecting a removable device. However, I would like to enable my program to detect that USB drive and read and print the text in that specific text file on my webpage. I also have a program code for reading and printing a text file from a USB but that program needs the drive letter to be specified. My problem is, how would I program if the drive letter is unspecified?
Here is my code by the way,
Code:
<%@ Import NameSpace="System.IO" %>
<%For Each d As System.IO.DriveInfo In My.Computer.FileSystem.Drives
If d.DriveType = DriveType.Removable Then
Dim test As String = File.ReadAllText(& ":\sample.txt")
Response.Write(test)
End If
Next
%>
How to let the string test get the data so that I could put it on my page. I'm currently using that File.ReadAllText method.
i want to type in a name to a textbox like type in "Ben" to textbox1. Then i want to click a button and have correlating numbers, say 126 show up in the textbox2. Im using a function to do this, how would i write a function that takes the string in textbox1, goes through each letter and sends back a numerical value for the letter through the function. I know how to do this with text files with stream reader, but don't know how to do this with strings.
