C# : Is there a way to save a Window as PDF?

I am using C# to generate a Window (scrollbar) with a lot of results: Window ResultsWindow = new Window();
At the bottom, there are two buttons, i.e. Cancel and Print. The first one does what it should. Nevertheless, the Print button should somehow convert the Window into a PDF File, or maybe one step inbetween where the user can save it afterwards.
private void Print_click(object sender, RoutedEventArgs e)
{
//add code to print the whole window??
ResultsWindow.Close();
}
Does anyone of you have an idea how this could work?
Best regards

This isn't particularly pretty (or tested) but uses information from this answer.
This creates an XPS file of your window, and converts it to PDF
using System.IO;
using System.IO.Packaging;
using System.Windows;
using System.Windows.Xps;
using System.Windows.Xps.Packaging;
namespace WpfApp8
{
/// <summary>
/// Interaction logic for MainWindow.xaml
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
/*
* Convert WPF -> XPS -> PDF
*/
MemoryStream lMemoryStream = new MemoryStream();
Package package = Package.Open(lMemoryStream, FileMode.Create);
XpsDocument doc = new XpsDocument(package);
XpsDocumentWriter writer = XpsDocument.CreateXpsDocumentWriter(doc);
// This is your window
writer.Write(this);
doc.Close();
package.Close();
// Convert
MemoryStream outStream = new MemoryStream();
PdfSharp.Xps.XpsConverter.Convert(lMemoryStream, outStream, false);
// Write pdf file
FileStream fileStream = new FileStream("C:\\test.pdf", FileMode.Create);
outStream.CopyTo(fileStream);
// Clean up
outStream.Flush();
outStream.Close();
fileStream.Flush();
fileStream.Close();
}
}
}
It uses the PdfSharp nuget package and the kenjiuno.PdfSharp.Xps package to add XPS support to PdfSharp

Asuming you are using WPF, here is how I accomplished something similar:
private void Button_Click(object sender, RoutedEventArgs e)
{
var wasMax = this.WindowState == WindowState.Maximized;
UBlattWindow.WindowState = WindowState.Normal;
var initHeight = UBlattWindow.ActualHeight;
var initWidth = UBlattWindow.ActualWidth;
UBlattWindow.Width = 955;
UBlattWindow.Height = UBlattWindow.Height + (ScrollerContent.ActualHeight - Scroller.ActualHeight) + 20;
Print(printGrid);
UBlattWindow.Height = initHeight;
UBlattWindow.Width = initWidth;
if (wasMax)
{
UBlattWindow.WindowState = WindowState.Maximized;
}
}
private void Print(Visual v)
{
System.Windows.FrameworkElement e = v as System.Windows.FrameworkElement;
if (e == null)
return;
PrintDialog pd = new PrintDialog();
if (pd.ShowDialog() == true)
{
PageMediaSize pageSize = null;
pageSize = new PageMediaSize(PageMediaSizeName.ISOA4);
pd.PrintTicket.PageMediaSize = pageSize;
//store original scale
Transform originalScale = e.LayoutTransform;
//get selected printer capabilities
System.Printing.PrintCapabilities capabilities = pd.PrintQueue.GetPrintCapabilities(pd.PrintTicket);
//get scale of the print wrt to screen of WPF visual
double scale = Math.Min(capabilities.PageImageableArea.ExtentWidth / e.ActualWidth, capabilities.PageImageableArea.ExtentHeight /
e.ActualHeight);
//Transform the Visual to scale
e.LayoutTransform = new ScaleTransform(scale, scale);
//get the size of the printer page
System.Windows.Size sz = new System.Windows.Size(capabilities.PageImageableArea.ExtentWidth, capabilities.PageImageableArea.ExtentHeight);
//update the layout of the visual to the printer page size.
e.Measure(sz);
e.Arrange(new System.Windows.Rect(new System.Windows.Point(capabilities.PageImageableArea.OriginWidth, capabilities.PageImageableArea.OriginHeight), sz));
//now print the visual to printer to fit on the one page.
pd.PrintVisual(v, "My Print");
//apply the original transform.
e.LayoutTransform = originalScale;
}
}
Note that I use the method Print to scale the Window, so it will fit a ISOA4 format. I also set my window to a fixed width and height before the print and reset it afterwards.

Adding Page Numbers

I haven't really written anything outside of Powershell in a long time, and I know this is ugly, but I can't seem to figure out why my new PDF is not adding the page numbers. I pulled the example from this itext kb.
I tried to make this basic app so people in the office could add the page numbers to PDF's. Here's what I have so far. It will create the new PDF (duplicate of the original), but it's not adding the page numbers.
Basically they use button1 to find their PDF via the Windows File Explorer dialog. It just stores the filename in a textbox. The second button is the "save" and should take the src file and make a copy of the src with only adding the page number at the bottom of the file (or anywhere at this point).

if (result == DialogResult.OK) // Test result.
{
string file = openFileDialog1.FileName;
try
{
string text = File.ReadAllText(file);
size = text.Length;
textBox1.Text = file;
}
catch (System.IO.IOException)
{
}
}
Console.WriteLine(size); // <-- Shows file size in debugging mode.
Console.WriteLine(result); // <-- For debugging use.
}
private void button2_Click(object sender, EventArgs e)
{
Stream myStream;
//SaveFileDialog saveFileDialog1 = new SaveFileDialog();
if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if ((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
string SRC = textBox1.Text;
string DEST = saveFileDialog1.FileName;
FileInfo file = new FileInfo(DEST);
file.Directory.Create();
PdfDocument pdfDoc = new PdfDocument(new PdfReader(SRC), new PdfWriter(DEST));
Document doc = new Document(pdfDoc);
int numberOfPages = pdfDoc.GetNumberOfPages();
for (int i = 1; i <= numberOfPages; i++)
{
// Write aligned text to the specified by parameters point
doc.ShowTextAligned(new Paragraph("page " + i + " of " + numberOfPages),559, 806, i, TextAlignment.CENTER, VerticalAlignment.TOP, 0);
}
doc.Close();
}
}
MessageBox.Show("PDF Page Numbering Added!", "Pages Added",MessageBoxButtons.OK);
Application.Exit();
}
}
}

I'm a dumb dumb. The x,y coordinates were off as the value 812 for the height is off the page.

AutoPrintCls autoprintme = new AutoPrintCls(reportViewer1.LocalReport);
autoprintme.PrinterSettings.Copies = Convert.ToInt16(numericUpDown1.Value);

Symbol font is rasterized when printing from .NET application

I am creating a Postscript file from C# by printing to a Postscript printer set up to print to a file. I'm using the .NET PrintDocument class and Graphics.DrawString to render the text.
If I use a symbol or pictograph font such as Symbol or WingDings, the text is rasterized in the Postscript file. If I use e.g. Arial, then the text is not rasterized. My aim is to produce a Postscript file from my application where text using a symbol font is not rasterized.
If I print the same text using symbol font from e.g. notepad the text is not rasterized, so it doesn't at first glance appear to be a printer driver limitation.
What am I doing wrong/different that's causing the rasterization?
The printer's font substitution table is set to not substitute the font.
Symbol font is available on the printers I have tried.
Choosing another Postscript printer driver makes no difference.
Using the TextRenderer.DrawText produces the same result.
Printing using the Symbol font from other applications (Notepad, Word, etc) does not result in rasterized output.

This turned out to be a bug in Windows 2012R2, 10, Server 2016, and Server 2019 (server 2008R2 was unaffected, which led us to open an MS case). Only some fonts were affected. It was resolved in the March 2021 OS updates for Windows 10, Server 2016 and Server 2019

How to change the permission level, download file

I try to create a web browser. Currently I try to realize a function that if the user wants to download some file an additional window is shown with a list of already downloaded files. If the file has already been loaded, a message is shown (just an idea).
So far, I get a link to the file location in the main form and send it to the other form:
DownLoadFile dlf = new DownLoadFile();
...
WebBrowser wb = new WebBrowser();
wb.Navigating += new WebBrowserNavigatingEventHandler(wb_Navigating);
...
private void wb_Navigating(object sender, WebBrowserNavigatingEventArgs e)
{
...
if (e.Url.ToString().EndsWith(".mp3"))
{
dlf.DownloadPath = e.Url;
dlf.Show();
}
}
In the new form I try to use this link for file downloading:
public Uri DownloadPath { get; set; }
...
private void DownLoadFile_Load(object sender, EventArgs e)
{
string filePath = null;
//get FileName from URL
string[] ArrayForName;
ArrayForName = DownloadPath.ToString().Split('/');
saveFileDialogFile.FileName =
ArrayForName[ArrayForName.Length-1].Replace("%"," ").Trim();
if (saveFileDialogFile.ShowDialog() == DialogResult.OK)
{
WebClient client = new WebClient();
//get Url
Uri url = new Uri(DownloadPath.ToString());
//get place where want to save with default name
filePath = saveFileDialogFile.FileName;
//event for result
client.DownloadFileCompleted +=
new System.ComponentModel.AsyncCompletedEventHandler (client_DownloadFileCompleted);
//download
client.DownloadFileAsync(url, filePath);
}
}
void client_DownloadFileCompleted(object sender, System.ComponentModel.AsyncCompletedEventArgs e)
{
MessageBox.Show("Compleated");
}
My questions are:
Regarding if (e.Url.ToString().EndsWith(".mp3")) - How can i
change this for knowing not only when the user tries to download mp3 file,
but all types of files - maybe there is a better way
If i want to download a file using some link directly, I get the message "Currently you have not required permission for that" - How can I
change permission level for my web browser
If i finally get a link to the file and start to download it, as result just name of file (size of file 0 kb) - where i'm wrong.

my solution (maybe not the best one)
create event for webBrowser
wb.Navigating += new WebBrowserNavigatingEventHandler(wb_Navigating);
and in this event use next
if (GetWorkingWebBrowser().StatusText != null)
{
try
{
WebRequest request = WebRequest.Create(GetWorkingWebBrowser().StatusText);
request.Method = "HEAD";
using (WebResponse response = request.GetResponse())
{
if (response.ContentLength > 0 &&
!response.ContentType.ToString().ToLower().Contains("text/html"))
{
dlf.DownloadPath = e.Url; //move url to my form for dwnload
dlf.Show(); //show form
}
}
}
catch (UriFormatException)
{
}
catch (WebException)
{
}
}
GetWorkingWebBrowser() - method that return current active webBrowser on tab, meas webBrowser
