Hello,

I am trying to embed html output into my webform but could not figure out
how to so far.

The form will execute a Perl script with some parameters, and script will
output some html code. I need to capture and render this html into my
webform.

Any ideas?

Thanks

Read the file into a string and set the Text property of a literal to the
value:

StreamReader sr = null;
string content = "";
try
{
  sr = new StreamReader("c:\\someFile.html");
  content = sr.ReadToEnd();
}finally
{
  if (sr != null)
  {
    sr.Close();
  }
}
SomeLiteral.Text = content;

Thanks, but there is no file to read from. The Perl script should be
executed, and then the outputting html should be rendered into the asp.net
webform.

I am basically looking for something like lwp in Perl
http://lwp.linpro.no/lwp/

to get the html and then some method to dynamically render it

Thanks

Opps..sorry, should have read your email more closely :)

From the MSDN Process documentation:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemdiagnosticsprocessclassstandardoutputtopic.asp

Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "test.exe";
p.Start();
p.WaitForExit();
string output = p.StandardOutput.ReadToEnd();

Is that more what you are looking for?

Nope. I am not trying to run an executable, I am trying to retrieve a web
page into my asp.net webform. Here is an example,

for example let's say we have a webform called test.aspx

when we run test.aspx

we should have something like

private void Page_Load(object sender, System.EventArgs e)

{

Label1.Text="Hello World";

string
x=getpage("http://www.google.com/search?hl=en&lr=&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&q=asp.net+&btnG=Search");



render(string);

Label2.Text"Bye Bye";

}

getpage() should be able to retrieve all html from the given url, now the
second challenge is to actually render this into the test.aspx so I might
have something like:

Hello World
[
Google Page
]
Bye Bye

I thought Microsoft had already done something similar but I could not find
anything.

Thanks

heh...well, we are getting closer :)  seems like you want some screen
scraping..  a google search for C# screen scraping should get you somewhere.
You can do it with the HttpWebRequest class, or with a web service.
