Hi,

I have created an asp.net c# application to convert HTML file to PDF.
For conversion I have used an external exe named wkhtmltopdf(an executable file) to convert HTML to PDF.
I used class Process to call the exe and everything is working fine.

Now I wanted to show progress bar displaying so and so percentage is completed, because converting large HTML to PDF takes time.

Reply me with how can I achieve the same.

You have two tasks here:
1) get the information
2) display the information
Where are you stuck?

Where is your code. does your third party code provide progress information for the same?

Below is the code i used to call exe

var p = new System.Diagnostics.Process()
{
StartInfo =
{
FileName = pdfHtmlToPdfExePath,
Arguments = urlsSeparatedBySpaces + " " + outputFilename,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
RedirectStandardInput = true,
WorkingDirectory = outputFolder
}
};

p.Start();
var errorOutput = p.StandardError.ReadToEnd();
p.WaitForExit(60000);
p.Close();

Additionally, I have used below code to read status from the console window,
while (p.HasExited)
{
Response.Write(p.StandardOutput.ReadLine());
}

Surely this will only work if the 3rd party tool the OP is using provides Callbacks ?
