Printing A File From List Collection?
Nov 16, 2009
I have a program in which I display a list of files in a ListView control and then send them all to a printer. I verified that the file is getting from the list to the print routine;however, I cannot seem to get the print function working right. I have tried several methods after reading many forum posts and articles to no avail. I listed my print routine below for reference; I send the file to the ReadFile sub that programatically creates the Print Document and then calls the Print page event. All in all rather simple, but I keep gettting about a dozen lines of blocks and arbitrary characters and then my document starts printing. I thought that by defining the SizeF structure in the MeasureString method and the RectangleF in the DrawString method I would clear up the problems
Private Sub ReadFile(ByVal _pfile As String)
Try
'Dim fs As FileStream

I basically have an application that generates reports in a .html file, I use a .html file for the ease of making tables and formatting text.Now I would like to introduce a way of printing the reports from my program. Because I use a .html file, the formatting would not the correct if I was to print it directly from my application (as far as I know). For this reason, I would like to print it just like my web browser would have in order to keep the tabular data intact and the text formatting.

I am wondering, what is the most efficient way to print from a listview. The listview's values are loaded from a database, and I would like to print from that listview. So far I have tried moving them to a text file and printing the text file, but Windows said that "The file is to large for notpad" even though I was not using notepad.
Is it advised to create an array of structures and then load everything into the array? If so, do I create the array dynamicly?

I have a requirement to print a number of records from a database. Each record refers to a second database that holds x number of related records. Just like and invoice header and line items.
I first print the report heading on the first page Something like "Invoice list for May 2012"
I then print the Invoice record headings under the the report heading Something like "Inv# Cust # Cust Phone Address 1 Address2 etc"
I then print that data from the original recordset Something like 1234 DR127 555 555-1212 Somewhereville 245th street
I then print the Line item headings Something like "Ln# Item# Description Qty Cost Selling Extn"
NOW Here is my problem: I never know how many line items there will be so can not predetermine when I will need a new page. I do have a way of telling when I am at the bottom of a page by using the text height and incrementing a value for each line
BUT I cannot figure out how to break out of the line item loop, start a bew page then carry on where I left off.
Once all the line items have been printed I need to start the next invoice by printing the Invoice record headings again followed by the header data followed by the line item headers followed by the line items for that invoice.
I have said that the page break may come while in the line item loop but it actually cold come anywhere in the overall loop.

I've searched and searched for an answer to my question, but as of yet, have yet to find a solution to what I'm looking for. My background - 6 months out of College (Computer Studies)
Right now I'm working on a program that is going to be used to handle database information (Access 2007). On the main form the user can select 3 pieces of required info from drop down list boxes. Those are required. Then after that they are able to enter a first name and a second name. They then add that name to a list box below. They can add as many names as they want to a list box. Then from there they have the option to either just save the info, or if required (which will more then likely be the main option) print each person in the list their own certificate. I have designed a separate form laid out the way required for the certificate.
The trouble that I'm having at this time is that I am unable to make the printing process show all of the certs that are going to print in a print preview. I have been able to get it to only show one. The form is set to load where hidden = true.

I was wondering if its possible to bind a datagrid column to a list (Of T) thats stored within an observable collection!
Here's my current code:
Dim _BindWithThis As New List(Of BindWithThis)
Me.DataContext = _BindWithThis
For i = 0 To 3
[Code]....
This currently displays four rows of "(Collection)". Is it possible to step into one of these "Collection" rows and display the data? I know that this is possible to do with a list box by binding with a specific element in the collection:
ListBox1.ItemsSource = _BindWithThis.Item(0).DataValue
I just can't work out how to do this with a datagrid...

I wanted to know if it's possible to remove a paticular item in my collection and then add it back at a certain location? e.g. say I use RemoveAt and remove the first item in the colleciton; after, I want to add it back at a particular location (index)? Maybe this isn't possible with this type or any other type collection?

If I run my web service code, it generates a serialized XML with only one level, that is,ParentElement and ChildElement. My goal is to make it a multiple XML levels that even grandChild will show, as the sample output below. How can I achieve this using List ollection looping. Do I need to create several functions that returns List objects for each column of the dataset I have?

I'm not to sure if this is possible this way but I'll try to example what I'm trying to do, I want to raise an event from a class but the class is in a List(Of Collection) for example
A - I have a usercontrol
B - That has Groups
C - The groups have children
The control would be similar to listview/Treeview
Below is the cutdown versions of my classes
Code:
Public Class InfoChildren
Private mText As String
Public Event TextChanged(ByVal Sender As Object, ByVal e As TextChangedEventArgs)
[Code]....
the reason for this is one of the child nodes keeps the current synchronisation time in a project but I need a way to update the text field(I have done this) but refresh the child display?

I am creating an instance of a Generic List collection and I am surprised to find that I can't add more than one value to it at a time. I was thinking there was going to be something like what you can do with arrays, where you can add a group of values to it at creation. I saw the AddRange method, but that seems to add another collection to the end of this collection, which is not what I want. So my code is:
vb
Dim MyList as New List(Of String)
MyList.Add("John")
MyList.Add("Bob")

I'm trying to populate class properties where one property is a list collection. I get a NullReferenceException when trying to add to the list collection. The code (litlle bit simplified) is here:
Public Class Portfolio
Property Name As String
Property Assets As List(Of Asset)
Public Sub Populate(ByVal data As DataTable)
For Each row As DataRow In data.Rows
[Code] .....
I have a nested class "Asset" inside the class "Portfolio". Everything goes ok until the line
Me.Assets.Add(asset)
Which gives me the NullReferenceException error.

Is it possible to have a two-dimensional array/list/collection such as the following. The first dimension is to have 2 elements, 0 and 1. The second dimension I would like to be able to have a different number of elements for each of the elements in the first dimension. To explain better, I'd like X in array (0, X) to go up to say 4 and Y in array(1, Y) to only go up to say 2.
So there would be:
array(0,0)
array(0,1)
array(0,2)
array(0,3)
array(0,4)
array(1,0)
array(1,1)
array(1,2)
But no array(1,3) or array(1,4).
I'd also need to be able to use Redim Preserve to increase the size of the second dimension for each of the first dimension's elements.

I'm am creating a "pop-up" CheckedListBox over a button on my DataGridView. The values in the list are going to be filtered based on the value in column 0 of the DataGridView.I have already pulled in a "master" DataTable with two columns: ACODE and MATRIX.I want to call the following function and return an array of strings that I can use to build this CheckedListBox with. The line between "For Each r" and "Next" generates a "Number of indices is less than the number of dimensions of the indexed array". The number of items is variable in the array so I can't predefined it. I know I'm going down the wrong path.

I've been building a simple card game in VB using VB 2010 express. I've built a simple Card class, as follows:
Public Class Card
Public Property Number As Integer
Public Property Suit As String
Public Property Image As String
End Class
I setup a base deck to create the unique, individual cards, which will then be used in multi-deck games. I have a game table form where the cards will be displayed. I declared this base deck inside the game table form and built it during the form's load event:
Public Class Main_Table
Public baseDeck As List(Of Card) = New List(Of Card)
Private Sub Main_Table_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim myCard As Card = New Card()
[Code] .....
Everything runs fine up until the end of Main_Table_Load. I've inspected the baseDeck values and they are correct. But when the Build_Deck_Click sub is invoked, the baseDeck collection's values become all the same, specifically it becomes composed of copies of the last card I built. I've stepped through the code and expanded baseDeck to confirm that all Cards become the same. I've tried moving the Public baseDeck As List(Of Card) = New List(Of Card) to a different module, with the same results. Since I will be using the baseDeck list through the app, I can't declare it privately inside the form_load event, as I'd have to re-create it every time I need to use it.
