Gday,

I am writing a large amount of reports for my vb.net application, every report has and identical header and footer of each page. I dont want to re-write the code to produce these headers and footers for every report I create.

Is there a way with using the printdocument function in VB.Net to create a function or the like that can return a header and/or footer and insert it into the document? I have done some searching of google and EE to no avail.

Any help would be appricated!

Assuming that you use the PrintDocument-object and build your page in the PrintPage-event, you can create a seperate function that creates the header/footer for the page. You can then call that function/those functions from within the printpage-event to build the header and/or footer.

You don't. You will pass the page-object as an argument to your function which will draw the desired items on the page and then returns. After that, you can continue your page-event drawing whatever you more want on that page.

A simple example:
Private Sub PrintHeader(ByRef e As System.Drawing.Printing.PrintPageEventArgs) 
    ' Draw title '
    e.Graphics.DrawString("Report Title"), New Font("Arial", 16), Brushes.Black, 95, 70) 
 
    ' Draw footer '
    e.Graphics.DrawImage(DirectCast(mResources.GetObject("footer_logo"), Drawing.Bitmap), 95, e.PageBounds.Height - 87) 
    Dim drawFont As New Font("Arial", 8.75) 
 
    e.Graphics.DrawString("Report Title", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 90) 
    e.Graphics.DrawString("Printed", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 76) 
    e.Graphics.DrawString("Printed By", drawFont, Brushes.Gray, 190, e.PageBounds.Height - 62) 
 
    ' Draw some grid lines to add structure to the footer information '
    e.Graphics.DrawLine(Pens.Gray, 246, e.PageBounds.Height - 90, 246, e.PageBounds.Height - 48) 
    e.Graphics.DrawLine(Pens.Gray, 188, e.PageBounds.Height - 75, 550, e.PageBounds.Height - 75) 
    e.Graphics.DrawLine(Pens.Gray, 188, e.PageBounds.Height - 61, 550, e.PageBounds.Height - 61) 
 
    e.Graphics.DrawString("Report", drawFont, Brushes.Black, 250, e.PageBounds.Height - 90) 
    e.Graphics.DrawString(Date.Now.ToShortDateString & " " & Date.Now.ToShortTimeString, drawFont, Brushes.Black, 250, e.PageBounds.Height - 76) 
    e.Graphics.DrawString("Arkro IT", drawFont, Brushes.Black, 250, e.PageBounds.Height - 62) 
End Sub

Private Sub PrintPage(ByVal sender As Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) 
    PrintHeader(e)

    ' Add your extra code for additional report-information here'
End Sub
