I am reading from a text file and then printing the string using printdocument via vb.net 2010.
Here is my code :
Public Class myPrinter
Friend TextToBePrinted As String
Public Sub prt(ByVal text As String)
Dim psize As New System.Drawing.Printing.PaperSize("Custom Paper Size", 850, 550)
Dim newMargins As New System.Drawing.Printing.Margins(0, 0, 0, 0)
TextToBePrinted = text
Dim prn As New Printing.PrintDocument
Using (prn)
prn.PrinterSettings.PrinterName = frmStockOut.printer
prn.PrinterSettings.Copies = frmStockOut.copies
prn.PrinterSettings.DefaultPageSettings.PaperSize = psize
prn.PrinterSettings.DefaultPageSettings.Margins = newMargins
prn.DefaultPageSettings.PaperSize = psize
prn.DefaultPageSettings.Margins = newMargins
AddHandler prn.PrintPage, _
AddressOf Me.PrintPageHandler
prn.Print()
RemoveHandler prn.PrintPage, _
AddressOf Me.PrintPageHandler
End Using
End Sub
Private Sub PrintPageHandler(ByVal sender As Object, _
ByVal args As Printing.PrintPageEventArgs)
Dim myFont As New Font("Courier New", 11)
args.Graphics.DrawString(TextToBePrinted, _
New Font(myFont, FontStyle.Regular), _
Brushes.Black, 50, 50)
End Sub
End Class
Private Sub PrintDocument1_PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim charactersOnPage As Integer = 0
Dim linesPerPage As Integer = 0
' Sets the value of charactersOnPage to the number of characters
' of stringToPrint that will fit within the bounds of the page.
e.Graphics.MeasureString(stringToPrint, Me.Font, e.MarginBounds.Size, _
StringFormat.GenericTypographic, charactersOnPage, linesPerPage)
' Draws the string within the bounds of the page
e.Graphics.DrawString(stringToPrint, Me.Font, Brushes.Black, _
e.MarginBounds, StringFormat.GenericTypographic)
' Remove the portion of the string that has been printed.
stringToPrint = stringToPrint.Substring(charactersOnPage)
' Check to see if more pages are to be printed.
e.HasMorePages = stringToPrint.Length > 0
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
ReadFile() ' will read text file and store in a string
Dim Print As New myPrinter
Dim myprintdialog As New PrintDialog
With myprintdialog
If .ShowDialog = Windows.Forms.DialogResult.OK Then
printer = .PrinterSettings.PrinterName
copies = .PrinterSettings.Copies
Print.prt(stringToPrint)
End If
End With
End Sub
The problem is even after I set the left margin and top margin to 0, it seems nothing has changed, it is still printing almost 3/4 inch for top margins and 1 inch for the left margin. This is also the output when I didn't set the margins. However, when I prn.OriginAtMargins = True , the output becomes a little different, left margin is now almost 1/2 inch but top margin remains the same. Something wrong with my code?
What I want to accomplish is the top margin can be set at approximately 20 pixels (assuming 100 pixels is equal to 1 inch) and left margin be set at 20 pixels too. Hope somebody can help me.

I am trying to write (type) directly onto a bitmap. I need to be able to type at the mouse position, so where ever on the screen i click the mouse, I can start typing text with the keyboard.
Here is a working VS 2017 VB Win Form code that will print "Hello World" at the mousedown position. But it only works with predetermined text. I would like to be able to just type at that spot. I feel I am so close, just can't get it to work.

This is a simplified code. Actually, the background image is only created once, but I added code to dynamically create it here to make the demo better.
I am new to programming. Can anybody help me with creating line/shape in picturebox with grips on the line/shape. Like we do it in CAD softwares.
And i want to know how to create a line on mouse click until another mouse click event occurs.

But it creates the line continuously from selected point. Whereas I want to create a line only for showing user the path of line. And i have implemented selection rectangle an right click button
Procedure for working:
Toolbar will contain line and Area
Open a file(image file)
click on line button of toolbar
*Come to picturebox
*click on one point of screen
*dynamic line starts drawing on screen (line will be from the 1st clicked point to where ever mouse mouse)
*when user clicks the next time the line is created.
click area of toolbar
*come back to picturebox
*operation same like line but when user clicks third point on picture box a shaded rectangle should appear.
http://www.vb-helper.com/howto_2005_line_control.html
For those who want to implement line with resizing grip in it.
For adding re sizable line you need to add a customized control of your own. Use this custom control and add/use it in form for further use.
Thanks everyone for helping
i am developing a school management software in which i have given a small handy functionality of a mini notepad so that it can make notice or doc within the software.
I have taken a RichTextBox for this, Now my problem is that when i enter text in richtextbox without giving space in between ( eg. aaaaaaaa..........) continous for 2 lines and when i click on PrintPreview, it leave some space from it start displaying on left but the text leaves the page from right side.
What i want is that i should a margin on both the side i.e. left & right side.
Below is my code on Print Document Click
Private Sub PrintDocument1_PrintPage_1(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim font1 As New Font("Arial", 12, FontStyle.Regular)
'Dim formatF As StringFormat = StringFormat.GenericDefault
'formatF.Alignment = StringAlignment.Center
'formatF.LineAlignment = StringAlignment.Center
e.Graphics.DrawString(RichTextBox1.Text, font:=font1, brush:=Brushes.Black, x:=10, y:=50)
End Sub
So it basically do is represented in below images. Please have a look.
Text in richtextbox
Image of print preview

If the printer is set to do duplex printing by default then duplex printing will occur automatically if you print a document that is more than one page. You need to have a look at the PrintPageEventArgs.HasMorePages property. You need to set this to True after printing the first page.
