Printing html file from windows application is not working when we set default browser as chrome (other than IE)

I have to print html file when user clicks on print button and it is working fine (prompts print dialog) when I set default browser as IE.
If I change default browser to chrome or firefox other than IE, the code does not prompting print dialog instead it just opens html file in the browser. Can you please let me know what configuration I have missed in the below code?
string TempFile = #"D:\test.html";
ProcessStartInfo Params = new ProcessStartInfo();
Params.FileName = "iexplore.exe";
Params.Arguments = TempFile;
Params.UseShellExecute = false;
Params.Verb = "print";
Params.WindowStyle = ProcessWindowStyle.Hidden;
Params.CreateNoWindow = true;
Process.Start(Params);

Finally I got the solution for this issue. The below code works like a charm!!
using (Process exeProcess = new Process())
{
string TempFile = #"D:\test.html";
exeProcess.StartInfo.FileName = "rundll32";
exeProcess.StartInfo.Arguments = #"system32\mshtml.dll,PrintHTML """ + TempFile + #"""";
exeProcess.StartInfo.UseShellExecute = true;
exeProcess.Start();
}

Print Save as PDF

I have the below code. As per my knowledge it is converting and saving as pdf. Can anyone explain this code?
Process cnp = new Process();
cnp.StartInfo.FileName = "AcroRd64.exe";
cnp.StartInfo.Arguments = "/n /t c:/test.jpg Microsoft Office Document Image Writer";
Updates:
I created a sample console application to trigger print and it is not working
class Program
{
static void Main(string[] args)
{
try
{
Process p = new Process();
p.StartInfo.FileName = #"C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe";
p.StartInfo.Verb = "Print";
p.StartInfo.Arguments = "/n /t c:/test.png " + "Microsoft Office Document Image Writer";
p.StartInfo.CreateNoWindow = false;
p.StartInfo.UseShellExecute = true;
p.StartInfo.WindowStyle = ProcessWindowStyle.Maximized;
}
catch (Exception ex)
{
Console.WriteLine(ex.ToString());
}
Console.ReadKey();
}
}

Process is used to start and stop processes on your system.
Seems pretty clear that your code attempts to start a process "AcroRd64.exe", which I would guess is the pdf-reader Adobe Acrobat Reader. Argumens are arguments to the process, so basically, this is the equivalent of writing the following in command line:
AcroRd64.exe /n /t c:/test.jpg Microsoft Office Document Image Writer
There's a little more info on this under this other SO question.
Your code might doesn't work because the single argument Microsoft Office Document Image Writer contains whitespace. Try:
cnp.StartInfo.Arguments =
"AcroRd64.exe /n /t c:/test.jpg \"Microsoft Office Document Image Writer\"";

Access file in Resources C#

I would like to import to registry a .reg file that exist in project resources.
The way to import a reg file uses the path to the reg file:
Process proc = new Process();
proc = Process.Start("regedit.exe", "/s " + "path\to\file.reg");
Is it possible to do so with a file from resources? how do I get its path?

If it is in the project folder. i-e. The folder in which the project is runnung. you can access it directly : Process.Start("regedit.exe", "/s " + "Filename.reg");
you can get the current path by using
string path =System.AppDomain.CurrentDomain.BaseDirectory; // this will give u the path for debug folder
or
string projectPath= Path.GetDirectoryName(Path.GetDirectoryName(System.IO.Directory.GetCurrentDirectory())); //This will give u the project path.
you can use both and navigate arround to get the path to your desired folder. eg if you want to access a file in the Resource folder inside the project folder u can use projectPath+"\\Resource\\filename.reg"

If the file is embedded resource (and as such is not created on disk), it is best to read it like this and save it to a temporary file using:
var path = System.IO.Path.ChangeExtension(System.IO.Path.GetTempFileName(), "reg");
Process.Start(path);
It may not be necessary to change the extension if you don't start the file directly but use Process.Start("regedit", "/s " + path) like you described in your question. Keep in mind that the file path should be escaped so it's parsed properly as the command line argument, temporary file path, though, will not contain spaces, so it should be okay.

This is not tested code, but you get the steps I hope:
Process proc = new Process();
proc.StartInfo.FileName = "regedit.exe";
proc.StartInfo.Arguments = "/s";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardInput = true;
proc.Start();
StreamWriter stdin = myProcess.StandardInput;
var assembly = Assembly.GetExecutingAssembly();
var resourceName = "<regfile>";
using (Stream stream = assembly.GetManifestResourceStream(resourceName))
using (StreamReader reader = new StreamReader(stream))
{
stdin.Write(reader.ReadToEnd());
}

Text content in pdf is not converted using pdf2swf

I am running c# application in service mode. And i am using pdf2swf tool to convert odf to swf format. Images saved in pdf is converting. But if any test adding to pdf is not getting converted in service mode.
But when run as UI mode(Consoleapplication.exe) then everything is getting converted.
string inputFileName = this.Filename;
string outputFileName = inputFileName.Replace("pdf", "swf");
StringBuilder sb = new StringBuilder();
sb.AppendFormat("{0} -o {1}", inputFileName, outputFileName);
string executingDirPath = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Replace("file:\\", "");
string dataDirectoryPath = Path.Combine(executingDirPath, "pdf2swf.exe");
ProcessStartInfo psi = new ProcessStartInfo(dataDirectoryPath, sb.ToString());
psi.UseShellExecute = false;
System.Diagnostics.Process pdf2swf = new System.Diagnostics.Process();
pdf2swf.StartInfo = psi;
pdf2swf.Start();
pdf2swf.WaitForExit();
pdf2swf.Close();
pdf2swf.Dispose();

Direct using process to start pdf2swf.ext maybe had some privilege problems.I used another way to solve this problem,write a batch file,then running the batch file by process.
Batch file sample:
c:
cd C:\Program Files (x86)\SWFTools\
pdf2swf.exe -f -T 9 -t "%1" -o "%2"
Code in program:
Process p = new Process();
string path = basePath + "/plugin/ConvertToSwf.bat";//batch file path
ProcessStartInfo pi = new ProcessStartInfo(path, filePath + " " + swfPath);//passing the file path and converted file path to batch file
pi.UseShellExecute = false;
pi.RedirectStandardOutput = true;
p.StartInfo = pi;
p.Start();
p.WaitForExit();

I faced a similar problem recently. I solved the issue by adding a separate console application(Consoleapplication.exe) with administrative-rights that runs on my server without shell.
Also, try to upgrade to the newest version of pdf2swf.

FYI. I recently had this problem (thought it was fonts not being embedded but actually was missing all text in converted swf). What fixed it for me was to set:
pi.UseShellExecute = false;
AND set the working directory;
pi.WorkingDirectory = "C:\windows\temp"; // path where read & write is

doc/docx to postscript/ps

I want to convert a doc/docx file to postscript by C# without using Word save to file since Word saved a big ps file.
Also, I want to know if there is a way to optimize a PDF by C#.
can I do that?

did you find anyway so you can convert doc/docx to ps?I have the same problem.
I know that it's too late to help you, but you can use ghostscript for optimizing pdf
