Send A Not Selected Value In A List Box To String?
May 2, 2010
I'm trying to make a scheduling tool for my major at my school and I have a CourseEntryForm, RemainingCoursesForm and CoursesCompeltedForm.The CourseEntryForm has list boxes of courses that are required for graduation. I have been able to send the selected values of these list boxes to rich text boxes in the CoursesCompletedForm, however I need the courses that have not been selected in the list boxes to be sent to string that I can use in rich text boxes in the RemainingCoursesForm.I have tried using:ListBox.Items.ToString(RemainingCourses)when RemainingCourses is declared as string. I have also tried If statements to try to assign it, but I can never get it to work properly.

I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.

I have a list, and in my items are labeled like this:
"Work sound ex 0"
"Work sound ex 0"
"Home sound ex 14"
"Home sound ex 15"
"Home sound ex 16"
How can I just send the number in the selected list item to a variable so only "0", "14", "15", "16", etc. is sent and not the words like "home" or "sound"?

This program is supposed to allow the user to check items in a checked list box. If the item is checked, it goes into the Completed List Box on the right. The program then adds the unchecked items to the Pending list box on the left. I keep getting placement values (e.g. O,1,2) instead of the strings (e.g. "Key Returned") in the list box results (see photo attached)
Public Class frmCheckOut
Dim i As Integer
Dim cleaning As String = "Cleaning Inspection"
Dim damage As String = "Damage Repaired"

I've been working on a program lately. On the form load it loads a list box with a list of names from a .txt file. It's a sign in form, so when people click their name then the button it will write to a .txt file their arrival time, and the folder is their name. I can make it do it one at a time, but that's so inconvenient. I have the list box set so it accepts multiple selections, but I need to make it write the time for everyone.
how to delete the selected name from the list that would be extremely helpful, that way the person isn't signed in multiple times.

i have a sub that checks all drives on a computer;
Dim getInfo As System.IO.DriveInfo()
getInfo = System.IO.DriveInfo.GetDrives
For Each info As System.IO.DriveInfo In getInfo
TextBox1.Text = TextBox1.Text & info.Name & vbCrLf
Next
this shows all drives in textbox1. now if i select the drive i want, i can then check the free & total space with this sub;
Dim cdrive As System.IO.DriveInfo
cdrive = My.Computer.FileSystem.GetDriveInfo(TextBox1.SelectedText)
TextBox2.Text = TextBox1.SelectedText & " has " & cdrive.TotalSize / 1024 / 1024 / 1024 & "gb total space" & vbCrLf
TextBox2.Text = TextBox2.Text & "and " & cdrive.TotalFreeSpace / 1024 / 1024 / 1024 & "gb free space"
all this is good if i select the drive i want to check. but if i only click the drive, since no text is selected, the second sub does not work.is there a way to check at which index the cursor is, grab the item of the index, and pass it to the sub so i don't have to select the text itself?

I'm having a problem with a program I am re-making. I used to be quite good at this stuff but I stopped and now I've pretty much forgotten everything. In hopes of gaining my knowledge back, I wanted to remake a program I made years ago but I'm having a problem.
I'm trying to split a selected item in a list box. This is what the item looks like:
|DATA|DATA|DATA|DATA/ELSE|
I can split it fine using this code:
Private Sub ListBox1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListBox1.Click
Dim LineofText As String

I am passing hex values to a subroutine and creating a datagram based on those values. Unfortunately, some of the values sent to the routine may need to be replaced after calculating the checksum and the checksum, itself, may need substitution. I have all that figured out, but the problem I'm having is that I can't send the data in the format I have it

I'm trying to solve a problem regarding types of list. First of all I have a stored procedure in my DB which does a select of a single column and I try to proceed it in my app in VB. By making a method function I declared a DataTable that loads through the SqlCommand(with the CloseConnection behavior). After that I publicly declared a List(Of String) which needs to be populated with the rows/items from the stored procedure that is on the way. Below is my snippet of the code:
Dim dt As New DataTable()
Try
If conn.State = ConnectionState.Open Then
[Code]....
It's LPrefix = collection.Cast(Of String)() where I get an exception error telling me that I can't really convert it. The old fashion way is to iterate with for/for each loop but that's not what I want for best use of performance especially if the list will have thousands of rows from a single column. So basically, I want to insert those items from that DataTable to the List(Of String) without For/For Each loop.
Running on VisualStudio2010 Ultimate, .NET FrameWork 4.0.
