New To Listview And Populating Data
Aug 19, 2009
Can someone help me with this code? I just need to make it so there is no limitation on how much data is loaded in the columns or rows, it populates very nicely for smaller comma delimited files , but if I try to load something that goes for example over to AV column, it errors out.I don't care about VIEWING this data, I am just trying to get it into a LISTVIEW so I can access the data for other methods in my code.Index was outside the bounds of the array. [code]

I have started the familiarize myself with WPF and have gotten stuck with the ListView I've read a lot of documentation about binding and I can't seem to find how to populate a ListView programmatically. It seems like a lot of work to create the binding and classes, etc, just to fill a ListView.
1. If you want to populate a ListView with data that a user has inputted, is the correct way in WPF to populate the ListView with binded data?
2. How do you add items and subitems to a ListView in code? (There doesn't seem to be a subitems in WPF.)

I have a listview with 6 columns. The first, hidden, is a key value. The other five are FirstName, MI, LastName, Gender, and CurrentGrade. When I go to populate the listview, I pull a datatable and do this:
For Each dr As DataRow In dt.Rows
Dim lvi As New ListViewItem(dr("StudentKey").ToString)
For i As Integer = 1 To 4
lvi.SubItems.Add("")
[Code] .....
But when the form loads, I get the MI in the FirstName column, the First Name in the LastName column, the LastName in the Gender column, and the Gender in the CurrentGrade column. The MI is blank. I've run it in debug, and the correct values are in the correct subitems. But for some reason, when the ListViewItem is added to the ListView, the subitems get all jumbled.

I want to show a list of files and folders (names + their icons) inside a given directory with a ListView control or equivalent. I understand that ExtractAssociatedIcon gives you the icon of a file, not a folder. So what are my options for this objective? I don't really have a problem if I have to separate folders and files like the following.
Dim fi As New IO.DirectoryInfo(f) 'f is the path of a given directory
For Each subfolder As IO.DirectoryInfo In fi.GetDirectories()
ImageList1.Images.Add(My.Resources.FolderIcon)

I have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:
-1 form
-3 textboxes - textbox1, textbox2, textbox3
-1 label - label1
-1 combobox - combobox1
-5 buttons - button1, button2, button3, button4, button 5
the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..

[VB 2008]. I'm trying to populate a DataGridView based on information in the Items in a ListBox (specifically, the file names without hypens or file extensions) and the content of the actual files. The DataGridView is supposed to look something like this:
IDNon-Hyphenated File NameFile Data
1. Some fileThe sky is blue.
2. Another fileThe grass is green.
The Items in the ListBox (lstFiles) look like this:
C:UsersUsernameDesktopFolderAsome-file.txt
C:UsersUsernameDesktopFolderAanother-file.txt
What is happening is that the DataGridView is being populated, but it looks like this:
IDNon-Hyphenated File NameFile Data
1 Another fileThe grass is green.
2 Another fileThe grass is green.
It's adding the second file's information to the DataTable twice and not adding the first file's information at all.
Private Sub btnDoSomething_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnDoSomething.Click
Dim pattern As String = "([w:\w /]([a-zA-Z0-9-]+?).w+)"
Dim reg As Regex = New Regex(pattern, RegexOptions.IgnoreCase)
Dim mat As Match
For Each Item In lstFiles.Items

Cant really seem to get the table to fill, it appears always with blank fields, and tried many different ways. Currently using vb. net 2005 msvs.[code]

So another first timer question.I have user entered data from a form that gets put into separate strings. On another form i want this data to populate a Tree view when the user presses a button "Add data". There will be only one stage of parents and child. oParent and oChild. The oParent string will only have like 5 items but the oChild will have like 30 and these will be repeated for each oParent. Not sure how populate this, i cam guessing with some sort of For Each i in oParent, add i or whatever, but not sure of the syntax.

Let's say I have an employee class with ID, Forename, Surname, Initials and Email Address properties.
At present, you can construct an Employee object by passing a data row which, typically will include all these fields. However, sometimes I only want the ID, Forename and Surname but still want to populate an object.
[Code]...
However obviously if certain fields are not present in the data row, I will have an error. Is there a quick way of populating the object based on the fields that are present within the data row without a) having to have separate subs for each circumstance and b) without having to try / catch (or something similar) around each property? I know other languages have options like this - where if there is no value, it will be another value (i.e. a default).
