How Can I open a Exsting PDF File

[mzmishra]

Hi,

Is there any way I can open the exiting PDF file by clicking a button on my c#.net application.
Please note I have acrobat reader installed on my machine.

Yes there is a way, suggest try search the site for clues.

Look at the Proccess class.
You should be able to set ShellExecute = true; then pass in the path+filename of the pdf to run it

Thanks Platter.
Actually my application is a asp.net application whch is in webfarm.
I have written a function to open the existing file,but it did not do anything,no error message nothing.Please review the code if I am doing anything wrong.

private void OpenFile()
{
Process myProcess = new Process();

try
{
// Get the path that stores user documents.
//string myDocumentsPath = Environment.GetFolderPath(Environment.SpecialFolde r.Personal);
string myDocumentsPath=@"c:\new.pdf";

myProcess.StartInfo.FileName = myDocumentsPath ;
myProcess.StartInfo.Verb = "Print";
myProcess.StartInfo.CreateNoWindow = true;
myProcess.Start();
}
catch(Exception ex)
{
throw ex;
}
}

Ahhh, well that will try and open it on the server computer, not locally.

Is the pdf located on the client computer, or on the server?

Thanks Plater for your help.

Actually I am creating the PDF file in a server /webfarm.
and after creating it I am trying to open it locally.

I have used this code now and it is working for me

Response.ContentType = "application/pdf";
string filePath="path.pdf" Response.WriteFile(filePath);

look into allowing a user to download from asp .net

you will have to stream the file for the user to download it.
I think you can force it to only open it rather than save it.

but opening will save it in the cache anyways.

cheers
