Process.Start() not starting

[xzzy]

In the follwoing code, myProcess.StartInfo.FileName is set to a valid path:
c:\\hello.doc

The code produces the following error message: "%1 is not a valid Win32
application"

For c:\\hello.doc, I would expect the following code to open a Word document
in a normal window.
//code++++++++++++++++++++++++++++++++
Process myProcess = new Process();

try
{
LinkButton btnClicked = (LinkButton)sender;
int myID = 1;
myClass.GetByID(myID);
myProcess.StartInfo.FileName = myClass.myDirectory + myClass.myFileName;
myProcess.StartInfo.UseShellExecute = false;
myProcess.StartInfo.WindowStyle =
System.Diagnostics.ProcessWindowStyle.Normal;
myProcess.StartInfo.CreateNoWindow = false;
myProcess.Start();
}

catch (Exception ex)
{

//end code++++++++++++++++++++++++++++++++

Thank you,

John

Take a close look at what "myClass.myDirectory + myClass.myFileName;" returns.

I bet you're not getting a valid filename or directory path out of it.

asp.net because its a service and does not have access to the desktop,
can not start a window app only a command line.

if you want to start word (which is not recommanded), you need to use
the automation api.

But how could it possibly do that...?

ASP.NET runs on the server, not on the client...

ASP.NET (principally) receives HttpRequests from web browsers and responds
by streaming HTML back down to the web browser...

Your code will do the following:

1) create a new Process object on the webserver

2) look for the installed application which corresponds to the supplied
filename's extension - in this case, .doc

3) try to instantiate that application and run it in the Process object - on
the server, not on the client.

ASP.NET can't open browser windows - it needs to create client-side markup
(hyperlinks or JavaScript) to do that...

Are you trying to open a Word document on the user's computer?
If so, you're going about it the wrong way.
There are several ways to open a Word doc on the client, the simplest would
be this:
Response.Redirect("/PublicDir/MyWordDoc.doc")

the value of

myClass.myDirectory + myClass.myFileName

is

c:\\hello.doc

which is a file located on the server upon which asp.net is being served
from ( in other words, it's not on the client )

Actually you can -- only it won't be visible. Give it a shot. Try and start
notepad then check in task manager
