Printing from List View

 
0
 

Hello Daniweb, and thank you for taking the time to read this post.

I have a question of efficiency.

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?

Please, if anyone has any suggestions, let me know.

Thank you,
begginnerdev

Wow, that gives me a good reference point. Thank you so much.

Unfortunately, it will not convert from the previous version to Visual Studio 2010. I can't get into the file to view the code either. :'( Thank you for the help though.

.NET provide a flexible way to organize your data and print by using PrintDocument. The following is the "Hello World" example of using PrintDocument.

Dim WithEvents pd As New System.Drawing.Printing.PrintDocument

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        pd.Print()
    End Sub

    Private Sub pd_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles pd.PrintPage
        e.Graphics.DrawString("Hello World", Me.Font, Brushes.Black, 0, 0)
    End Sub

An example of printing a listview in details view.

Prints the columns to the current size as on the screen and prints images in the image list if one exists.

Public Class Form1

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        'Junk items for demonstation.
        For i = 1 To 100
            ListView1.Items.Add(New ListViewItem(New String() {"Dani", "Web", "Is", "Awesome"}, 0))
        Next

    End Sub


    Private Sub ButtonPrintListView_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonPrintListView.Click
        'Used printPreviewDialog instead of printdialog
        'to save paper while debugging.  When finished
        'swith out to PrintDialog.
        Dim PrintPreview As New PrintPreviewDialog
        PrintPreview.Document = PrintDocument1
        PrintPreview.ShowDialog()
    End Sub

    Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
        'The below is desined for details view.
