VB Code Case Statement - Added A List Box With A List Of Names
Jan 13, 2011
I am used to C like languages such as C#. I added a list box with a list of names. In the code behind I added the below code. When I run the code I am getting the MessageBox but it will state "UserName favorite color is " but does not show the color. I thought it might be misspelled or non-matching names but this is not the issue due to the names being correct.
Public Class Form1
Private Sub lstData_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstData.SelectedIndexChanged

when I add a Control to the List(Of Control) what gets added to the List? Is it the Control or reference to the Control.I have a collection of controls (picture boxes representing notes,comments, icons, etc.), which can be drag and drop into other picture boxes holding read only images. Those controls are never permamently added to those images, they can be move or dispose as needed. I need to save those controls to a file and retrieve it later, however when retrieved, they must be place onto the same location in the image. Saving just the image is not the option, I also need to save all the control attributes.

I have an application that contains both test code and production code. The test code points to the test files on the local machine while production is located on the server. I comment out the production code when testing. To save some time I figured I would create a Global Variable integer called pTest and encase the test and production code in a Case statement so that if I set pTest=1 then the test code will run and if pTest=0 then production code will run.

I have the following code in my page which works fine although the number of cases is much much bigger. I need to use exactly the same list of cases in other selects but I don't want to have exactly the same code duplicate all over the place.
[Code]...
This kind of works but there's a slight problem. I have to load the page twice for the phone number to change (or the phone number appears as it should have done on the previous load). Hope this makes sense.

If I have a list of filenames in a list, how can I do a case-insensitive lookup?
Dim files As List(Of String) = IO.Directory.GetFiles(myFolder).ToList
If files.Contains(myFileName) Then
'do something
End If
The above snippet will only do a case sensitive search.

I am taking a VB course for school and I am having difficulty with a program I'm making.
The program is essentially a shopping list that adds the cost of everything up.
But I cannot get an additional item added to the Text file to add with the list.
Ive attached a screenshot of the program and my code..

how to list names from a file, as you enter (spell) the name. eg if you enter 'b' all 'b' names will appear. If you next enter 'e' then all 'be' names will appear. repeating this until the last letters are entered. eg 'bell' will show all names starting with 'bell'. You can then select from the list the correct name?

I have added information from a file to be displayed in a list box. I am displaying two pieces of information per line (reward and reward cost)They are being displayed correctly, but they are not aligned properly, for example:[code]I have used a fixed string length when saving the names to the file (.dat)I am just wondering if there is a function that would sort the alignment out?

I've created a custom control that I insert into my window with the following code
Code:
<controls:ListExpander Text="Class Diagrams"></controls:ListExpander>
The control in question contains several subcontrols, among others, a list. How can create the setup, so I can specify items that should be added to the list?
Code:
<controls:ListExpander Text="Class Diagrams">
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
<SomeItem>data<SomeItem>
</controls:ListExpander>
In which case the SomeItem objects should be added to the list in the ListExpander:
Code:
<ListBox Name="lstItems" Background="LightGray">
<ListBox.Items>
// Items should go here
</ListBox.Items>
</ListBox>
I'm quite new to WPF, but I suppose it's something along the lines of creating a dependency collection on ListExpander that takes object of the type SomeItem? I simply want to be able to give the control a few arguments which it can translate into items in the listbox contained within the the control.

I have a very simple class that crashes the VB.NET IDE when I added this list. Granted this is a list with 10,000 items but it crashes when I added it to the project. When I delete it with a text editor outside the project does not crash. I have not installed SP1 based on the comments not sure if this is a know problem or not. I can post the project its fairly small as its just text.

I have an XML node which I am adding to a generic list of xml nodes:
ListXml.Add(myXmlNode)
Now whenever I change the node afterwards, all members of the list turn into copies of the node. Why would the list keep track of this and more importantly how am I supposed to 'detach' my work node from that list?

So in my Textbox I have a list of (folder) names, such as:
Folder1
Folder2
Folder3
I want to compare THAT list to another folder somewhere in someones documents (no specific folder). So let's say we compare it to the 'Arts' folder, which contain these folders inside:
Folder1
Folder2
I want to put all of those folder names in the Art folder into a list. And then I want to compare the folder names in my Textbox to the folder names in the Arts folder, and Folder3 is missing in the Art folder, so I want the textbox to contain:
Folder3
...to tell you that you are missing Folder 3 in your Art folder.

I am using VB.NET in VS 2008 Professional. I wish to have my user select the server where the SQL Database resides. I can get a list of the SQL databases, but I am stuck on how to display the servers currently available to the user? I want to add the list of servers available into a list box and have them select the server.
The thing I am trying to duplicate is the drop down list of server names when you are doing an Add Connection from the Data Connections node of the Server Explorer.

I am trying to find out if an instance of an application (not vb.net) is already running - because I will want to start it but I don't want to start it if it is already running. I have found a solution to check if a process is running:
Dim proc As Integer = Process.GetProcessesByName(ProcessName).GetUpperBound(0) + 1
and return True if >=1 (or just the process number). My problem is, this is a third-party application, and its process name is not just a name but it contains a version number (which I may not know at run time), and it also seems to add a *32 (so probably a *64 if it is installed in x64 ?).
I need to get a list of running processes, by name, and test if "processname" is a substring of the name.
But I haven't been successful in getting a list of names, only process id's.

I have a table in a Access Database that I'm loading into a VB.NET program and I want a way to get the name of each of the columns into a list of Strings. Googling has shown that this is much easier with a SQL database, but that doing so in Access is much more difficult. I came across this question Is there a query that will return all of the column names in a Microsoft Access table? Which gives a way to do it, but when I try the code it just populates my list with a bunch of "System.Collections.Generic.List'1[System.String]"
This is my adapted code.
Public Function GetColumns(ByRef database As String, ByRef table_name As String, ByRef columns As List(Of String)) As Integer
Dim com As OleDbConnection
Try
com = New OleDbConnection(database)
com.Open()
[Code] .....
My for each loop isn't printing the right string. Should be Console.WriteLine(holding)

I have a list of File_Name, File_Date.
I need to check this list sometimes against a file name and sometimes against both a filename and a file date.
I've been doing a for each loop and checking each value, I've tried a hash table keyed on file_name which is much faster, however I also need to check to see if the file_name and File_Date combination exist.
Is it possible to have a list that I can do a quick search on using either the filename or both the filename and filedate.

I am trying to write names from a list box and it works apart from the first listbox item.So this doesn't work:
My.Computer.FileSystem.RenameFile("D:Renaming2.avi", TextBox4.Text & " " & "1" & " " & "-" & " " & ListBox1.Items(0))
But this does:
MessageBox.Show(ListBox1.Items(0))
So listbox1.items(0) does exist but I just get the error that there are illegal characters in the path.
