Printing webpage using URL in c#

solarissf used Ask the Experts™

on 2011-05-16

Hello All,

Stuck on this and driving me crazy.

The end goal is to print an email in lotusnotes automatically. Already found the universalID of specific email.

Now I am trying to return url as a webpage through a proxy(using UNIVERSAL ID) and print it. Due to fact that no matter what I try I cannot get lotusnotes to print it automatically.

I've been able to retreive webpage, but do not know how to print it (and in a nice format)

any help would be appreciated

    public void FindWebPage()
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.msn.com");
        WebProxy myproxy = new WebProxy("http://autoproxy:81", false);
        myproxy.BypassProxyOnLocal = false;
        request.Proxy = myproxy;
        request.Method = "GET";
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();


System.IO.Stream _WebStream = response.GetResponseStream();

Why not dump it to a web page and immediately after call the javascript print function?

Next step is to read the response.

var reader = new StreamReader(_WebStream);
string text = reader.ReadToEnd();

Then you have the HTTP content in text, and need to format it up.

Then write the javascript after your write the text variable that mrjoltcola describes.

You could append the javascript to the text variable after your stream.

now what?

    public void FindWebPage()
    {
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.msn.com");
        WebProxy myproxy = new WebProxy("http://autoproxy:81", false);
        myproxy.BypassProxyOnLocal = false;
        request.Proxy = myproxy;
        request.Method = "GET";
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();


        System.IO.Stream _WebStream = response.GetResponseStream();
        var reader = new StreamReader(_WebStream);
        string text = reader.ReadToEnd();

Response.Write(text) or I would create a label on the page and set its text to the text variable.

text += @"<script language="Javascript">function printpage() window.print();}/script>"

sorry, I'm very new at this... you guys lost me on the last 2 lines.

Response.Write(text) or I would create a label on the page and set its text to the text variable
give an error
Response in underlined saying does not exist in current context

and
text += @"<script language="Javascript">function printpage() window.print();}/script>"
is this 1 line of code, I am getting underlined RED for the whole thing

text += @"<script language=""Javascript"">window.print();</script>" ;

Actually, use a literal control.

Two things.

1. I made the assumption that you were using a web site, not a windows application, my apologies. The Javascript isn't what you want to use here.

2. Step through your code and verify that the text variable is actually being populated with data. Then, worry about printing your form.

the text variable IS being populated... but I'm looking it at the LOCALS windows so I can't get a good picture of whats in there.

since I'm in a windows app, what is my next step.

very sorry for all these questions

Place a label on your form and set its text to the text variable. If you don't have room on the current form, open another and display the text there.

so I did that... apparently the information in there is all garbage. dont even know how to describe it.

Think this has something to do with my proxy?

hmmm...not sure if it's the proxy or not, it may be the way you're getting the data. I'm not sure about that--sorry.

That isn't garbage, that is the page itself. What you listed above is Javascript content from the page that you requested.

So you accomplished what you asked, but I think what you want to do is render the visible portion of the page and include that in the email.

shows what I know. Thank you.

I removed the new post and will keep this one only.

Since you are correct, and I want to return the visible portion of the page, how should I go about doing this?

No, I didn't mean that. You are welcome to open a new question. You can open as many questions as you like as long as they are not duplicates. Please just properly close this one.

The way I see it, you accomplished your original question's goal, but now you want something a bit more specific, like how to properly render the page in an email. That is a separate issue, so I think a new question may be in order, as it will bring in new experts.
