How do I simply open an ASP page and possibly pass it data from a C# form

[Brian F]

Exactly what the subject says.
I have an ASP page that I want my C# windows application to open in
Internet Explorer, and if possible have it send along a list of values
from a list box. Thank you.

[Brian W]

That would mostly depend on the page.

Does it take parameters, or are you trying to fill in textboxes on the page?

If the page take paramters build a string with the values and pass it to
System.Diagnost ics.Process.Sta rt something like this:

System.Diagnost ics.Process.Sta rt("http://www.myhost.com? parm1=value1&pa rm2=v
alue2");

heres a few classes i wrote a while back,

it probably needs a bit of tidying up, but it works

some nice functions for setting the values of an HTML form once the page has
loaded + submitting a button from a windows forms app.

The main one you'll be interested in though is...
public void Navigate(string _url, string _valuedatapairs )..

this method you just call like :

webcontrol.Navi gate("www.yahoo .co.uk","param1 =one&param2=two &etc=easyasthis "
);

if you want to pass values to an array from a list box, use a for loop, and
make each parameter the same name.... but you probably
know what to do from here.

also started doing some work on showing a custom context menu -

anyway, hope this helps

(you'll need to get VS.NET to create a wrapper for the WebControl) - i
haven't included it here

Brian,

In order to do this, you are going to have to create an instance of
InternetExplore r. Once you have that, you will have to connect to the
IWebBrowser2 interface, and then get the IHTMLDocument2 instance of the
document hosted in the browser. With that, you can access elements of the
DOM for the page that is being viewed, and subsequently manipulate it, etc,
etc.

To access internet explorer, you have to set a reference in COM to
SHDocVw.dll (Microsoft Internet Controls). Also, you will have to set a
reference to MSHTML.tlb, which there should already be a managed wrapper for
under the .NET tab in the references dialog, under Microsoft.mshtm l.
Hope this helps.

Nicholas,

Why?

The OP said he just wants to open his page in IE passing in the parameters,
he said nothing about the browser being imbedded on his form.

My solution may not specifically open IE but it will open the default
browser.

Brian,

My assumption is that when the OP said "pass it data" it meant to pass
it data from the app to a form on the page. If it is a form, then more
likely than not, it is going to be submitted with a POST, and not a get, in
which case, you can not just append the values to the URL. You would have
to automate IE in order to populate the form and submit it through an
external instance of IE.

Hi Nicholas,

I think that Brian's assumption is the correct one, the OP said an ASP
page, not an ASP.NET page, in ASP is usually used request["VARNAME"] and the
request object iterate in both the GET and POST collection ( do not remember
if those are the correct name ) so I think that his solution will do the
trick here.

[Nicholas Paldino [.NET/C# MVP]]

Ignacio,

Perhaps we should ask the OP? If they know that the request mechanism
uses GET in the HTTP protocol, then Brian's suggestion will work. However,
if it requires a POST, then my suggestion will have to be used, as the OP
will have to call the Navigate method to pass the POST parameters involved.

Also, whether or not it is an ASP page, ASP.NET, PERL, etc, etc, doesn't
matter. ASP doesn't lock you into using GET or POST exclusively for getting
data to the server from the client.

I didn't mean to start a holy-war. ;)

The only thing that is clear here is that we both interpreted the OP
differently, as such, we both answered appropriately given our differing
interpretations .

I know better that to second-guess Nicholas, I was just trying to understand
why he answered the way he did, and now I know ;)
