C# Print Word Document without opening Word or Printerselection

I tried using the code below, using PrintDocument, etc.. but can't get it to work.
Every time I run the Code below it opens a window asking me to select a printer. Using PrintDocument always led to empty pages, but the docs got printed.
How can I print Word documents without opening any windows?
foreach (string doc in dirFiles)
{
ProcessStartInfo info = new ProcessStartInfo();
info.Verb = "print";
info.FileName = doc;
info.Arguments = SelectedDrucker; //Printername
info.CreateNoWindow = true;
Process.Start(info);
}

Only the Word application can correctly print a Word document as it interprets the content/layout as it's sent to the printer. You first need to open the document in the Word application, then use its PrintOut method.
(This is also what Windows does when a user right-clicks a Word file and selects "Print".)
So there's no way to print a document without opening a window. You can, however, minimize the Word document window once it's been opened.

Print PDF hidden from user

I have a PDF printed from C# with this code:
ProcessStartInfo info = new ProcessStartInfo();
info.Verb = "printto";
info.FileName = segnToPrint;
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
info.Arguments = "\""+ stmp+ "\"";
Process p = new Process();
p.StartInfo = info;
p.Start();
p.EnableRaisingEvents = true;
p.WaitForInputIdle();
System.Threading.Thread.Sleep(1000);
// Close Acrobat regardless of version
if (p != null)
{
p.WaitForInputIdle();
p.CloseMainWindow();
}
stmp is the address of the printer. The print works fine and it's perfect but i see the windows of Acrobat Reader any time that i call this function and the page of Acrobat Reader remains open after the last file printed.
How can i hidden all the process to the user?

If you are looking to hide some window then you may try move its window left and top position outside the screen using SetWindowPos function (see C# code here).
But please be aware of user interactions as user could be confused by the program running in the taskbar but not available on desktop.

Unfortunately (as you have found) acrobat reader will always open a window. If you wish to silently print without ever seeing acrobat then the only approach would be to use something other than acrobat reader. Two possible options are to use another PDF reader like FoxIt or to try to send your PDF directly to the printer in raw form, getting round the need for 3rd party applications all-together.

how to print on a particular printer [duplicate]

I am making one application where user will print invoices which I am displaying using Crystal Report.
The user showed me his current application made using ForPro. In that application, under Printer Options form, one can see all the printers currently installed and the user could select default printer. When the invoice is made, the user presses the print button, then there is one dialog asking for no. of copies. When it's entered, the invoice gets printed directly, without any Print Dialog Box. If the user wants to change the printer again he/she will change it in the Printer Option form.
I want to know if similar thing is possible in Crystal Report and need guidance on how to approach for it.

Take a look at the ReportDocument.PrintToPrinter SAP Docs or MSDN Docs for how to specify the PrinterName and then Print using the ReportDocument object.
If you can try and get away from how the FoxPro app UI for printer selection. Instead use the standard print dialog box to select the printer.
You should note that if you don't set the PrinterName before sending the report to the printer it will use the default on the crystal file. Not to be confused with the user's OS default printer.
Here's an example of showing the PrintDialog settings some parameters using the SetParameterValue method and then sending the report document to a printer
// Note: untested
var dialog = new PrintDialog();
Nullable<bool> print = dialog.ShowDialog();
if (print.HasValue && print.Value)
{
var rd = new ReportDocument();
rd.Load("ReportFile.rpt");
rd.SetParameter("Parameter1", "abc");
rd.SetParameter("Parameter2", "foo");
rd.PrintOptions.PrinterName = dialog.PrinterSettings.PrinterName;
rd.PrintToPrinter(1, false, 0, 0);
}

The code above no longer works as advertised which has been admitted by SAP
You need to set the report document to an ISCDReportClientDocument and then print it. This is a more robust way of making sure the print job doesn't go to the default printer. The last two lines can be replaced with this code.
CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions printReportOptions = new CrystalDecisions.ReportAppServer.Controllers.PrintReportOptions();
CrystalDecisions.ReportAppServer.Controllers.PrintOutputController printOutputController = new CrystalDecisions.ReportAppServer.Controllers.PrintOutputController();
CrystalDecisions.ReportAppServer.ClientDoc.ISCDReportClientDocument rptClientDoc;
rptClientDoc = cryRtp.ReportClientDocument;
printReportOptions.PrinterName = pDialog.PrinterSettings.PrinterName;
rptClientDoc.PrintOutputController.PrintReport(printReportOptions);

How to print various file types programmatically

I am writing an app which performs some tests and produces a number of different reports. These may be any combination of Labels, PDF for end customer, PDF for repair department, XML file etc.
Depending on the report type, I need to send the file to either the file system or to one of a number of different printers (A4, label etc). Ideally there should be no popup windows - just straight to paper.
How can I send a file (PDF, XML) to a printer? I had thought that for XML/Text I could just File.Copy to LPTn but that doesn't seem to work. For PDF I'm guessing that I could call Acrobat with some parameters which cause the PDF to be printed.
The printers I use are mapped to LPTn. Is there a better way to do this and to store the definitions in the app? i.e. Labels go to MyLabelPrinter and A4 PDFs got to MyA4Printer.
Has anyone done this?

ProcessStartInfo info = new ProcessStartInfo("[path to your file]");
info.Verb = "PrintTo";
info.Arguments = "\"[printer name]\"";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(info);

Take a look at this webpage. You should find the info you are looking at for PDF.
For example, it will look like that:
ProcessStartInfo infoOnProcess = new ProcessStartInfo("C:/example.pdf");
info.Verb = "PrintTo";
//Put a if there, if you want to change printer depending to file extension
info.Arguments = "\"HP-example-Printer\"";
info.CreateNoWindow = true;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process.Start(infoOnProcess);

How can I get filename when user close Word?

I have one button and one textbox on form. When I click on the button, Microsoft Word is started. When the user closes Word, I want to get the file name that the user saved his work under to show up in the text box.
I am using the following code for button_click:
System.Diagnostics.ProcessStartInfo psi = new System.Diagnostics.ProcessStartInfo(#"C:\Program Files\Microsoft Office\Office12\winword.exe");
psi.RedirectStandardOutput = true;
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
System.Diagnostics.Process listFiles;
listFiles = System.Diagnostics.Process.Start(psi);
System.IO.StreamReader myOutput = listFiles.StandardOutput;
listFiles.WaitForExit();
if (listFiles.HasExited)
{
System.IO.FileInfo ff = new System.IO.FileInfo(myOutput.ToString());
string output = myOutput.ReadToEnd();
this.processResults.Text = output;
}

I don't believe this is possible via the command line. Also, realize that, if the user opens another document, your code will not finish, since it'll wait until all of the docs are closed (the process won't end until that point).
That being said, you should be able to use the Word/Office Interop libraries, and listen to the DocumentBeforeSave and/or DocumentBeforeClose events. This should let you pull the information from the Document itself, right as it's being saved/closed.

I don't think you can do this with the current code you have. ProcessStartInfo is very generic and has no knowledge of word.
I think you will want to use Visual Studio Tools for Office (VSTO) to start word. This way you have a reference to the word application and document and can get the document name.
this article should get you started http://www.c-sharpcorner.com/UploadFile/mgold/WordFromDotNet11082005235506PM/WordFromDotNet.aspx the sample code has a object called aDoc. Then after the save you can check aDoc.FullName to get the path.

I'm not sure whether it's possible or not because name of the saved file is an internal information that's not public for other applications.
Instead in your particular case since you are using MS Word you can use Word interop to start the Word application in your application and then handle its events

Create a blank Word document in the desired location, and then get Word to load that?
