Internet Explorer Web Browser Control Embedded

if you turn off viewstate for the page you are redirecting too, you can access the values passed using Request.Form,
like in old asp and post pages.  

Sean,

I am using the web browser control in vb.net and cold fusion as the scripting for the page. Once I have the data that I require to the web page I can take over with the cold fusion from there.

The key thing here is that the data is not seen by the user. The URL cannot be added to the history when navigation is complete. Is there code for this?

If you can post the form collection with the redirect, then you should be set ..

Example:

Response.Redirect("Page.cmf", true);

Then with the cold fusion page, just use the equivalent to Request.Form["objectname"] to get each value ..

Sean,

Do you have a code example of how I could acheive the whole process. Sorry don't quite understand at the moment.

Thanks

basically, the redirect method with that true parameter passed would send the entire form items collection with the redirect .. thus, you wouldn't have to use QueryStrings

Say for instance, you have a page with the following:

<form>
<asp:textbox id="text1" runat=server></asp:textbox>
<asp:textbox id="text2" runat=server></asp:textbox>

<asp:button id="cmdGoToColdFusionPage" runat=server text="Go"></asp:button>
</form>

now,

in the code behind for the button you'd do the following .. I don't think you'd need the dll at all that you are using .. you can do this completely in code ..

private void cmdGoToColdFusionPage_Click(object sender, System.EventArgs e)
{
   Response.Redirect("ColdFusionPage.cfm", true);
}


Then, in your cold fusion page, you can access everything through the forms collection like you would in old asp .. I'm not familiar how to do that in cold fusion, but in old asp you'd access it like the following:

Request.Form("text1")
Request.Form("text2")

Sean,

Here is the code that is being used.

me.ax1webbrowser.navigate2("url", flags, targetframe, postdata, headers)


Now in the URL I can pass the query string as well but that will be stored in the browser history, where values can be accessed. I am looking for a solution that will ideally stop this from happening or erase the history when the application exits, not using ASP. Remember that the application is a vb.net application with an embedded web browser activex control, using the shodcvw.dll library.

That is the solution I am looking for. Sorry If I did not make myself cler in the first place.

If someone can provide a solution using this method then that will be great! Thanks for your help so far

i think the parameter you need to pass is postdata, if you can somehow pass the forms collection to the postdata parameter, it will work ..

I have done this Sean and have no results. Any ideas? How I would construct the string etc. or some sample code for this.

you should just be able to send it Request.Form

this is not the solution I am looking for. Does every variable have to be specified when using the navigate or navigate2 method?

I want o really use the post data section of Navigate method. How would I get the data that I have into the postdata section of navigate and what format does it have to be? (e.g. string, object etc.)

It cannot be just string or object because the variables are not being passed. What can it be and how is it done?

Can nobody answer this question? Surely this has been done before?

I'm working on exactly the same problem.  If I can figure it out I will most definitely post my results here.  Sean doesn't quite grasp what is going on I don't think, since he keeps referring to server side ASP.NET stuff.

I've tried making a list of parameters and the converting it to a Byte array (the data type of the postdata parameter), but didn't have any luck.  I wasn't actually sure how to handle multiple parameters, or even what the format for a single parameter should be.  I am very surprised at how much documentation there ISN'T for this control.

Anyway, I'll update you if I figure out how to do it.

Thanks HummusX. I have been searching everywhere for this solution yet there are no examples of how to acheive this. Let me know if you have anything and likewise I will do the same. Thanks

HummusX and anybody else who needs to know. I have solved my problem. This is how I got round it...

 Private Enum BrowserNavConstants
        navOpenInNewWindow = 1
        navNoHistory = 2
        navNoReadFromCache = 4
        navNoWriteToCache = 8
        navAllowAutosearch = 10
        navBrowserBar = 20
        navHyperlink = 40
    End Enum

Dim BteArray() as Byte
Dim Url as String
Dim vHeaders As String = "Content-Type: application/x-www-form-urlencoded" + Chr(10) + Chr(13)

Ok so that is the variables declared. Now we use the navigate2 or navigate method below...

url = "http://www.xxxxxxxxxxx.com/index.cfm"
BteArray = System.Text.Encoding.ASCII.GetBytes("username=xxx&password=yyy&answer=hjhjh")

'The System.Text.Encoding.ASCII.GetBytes was the namespace that does the work for us so after, our final navigation statement looks like below'

Me.WebBrowser.Navigate2(url,BrowserNavConstants.NavNoHistory,System.DBNull.Value,BteArray,vHeaders)

This will then complete the navigation and post the form data with it that you have collected in your application. Hope this helps people as I have been stuck on this problem for ages!!! and now it's solved!!
