Set Cookies in a Webbrowser control

Hi All,
I have a problem regarding webbrowser control in windows phone 8. I have a Native Login page in the app where we login user through service. In response of the login service we get a token.
Now I have a page with WebBrowser control.In web browser control we open a url which has login page and dashboard. As the user is already logged in and we have the token. So we need to navigate user directly to dashboard instead of the login page.
To do this in webbrowser control we need to set Cookies in control. How can we do this task?
Please help me as we need to close this issue asap. Thanking you in advance.

I have a very similar authentication flow in my app. Using native calls (HttpClient) I am able to retrieve the authentication token, and can easily set a cookie with that token, and use the cookie with subsequent
native calls via HttpClient.
I believe that what you are asking for is the ability to add that cookie (with the token you got natively) into the webbrowser control's cookie store
BEFORE trying to load your dashboard page. You want your webbrowser control's request for the dashboard page to provide the cookie so that the user doesn't have to log
in again, and only one webbrowser request is made. Is this correct?
Sadly, I do not think this is possible. The other answers describe how to add a cookie to a webbrowser control's page after that page has been loaded. This is adding the cookie to the "document" within the browser control, not
into the webbrowser control's store. These approaches will not allow you to add the cookie into the webbrowser control's store, ahead of time, so that it will be sent when you first request the page.
If I am correct about what you are asking for (I want this too!) it is not supported on Windows Phone as you cannot write directly to the webbrowser control's cookie store. You can read it, but not write to it. It's sad as this particular
authentication flow is very common, and easy to achieve on both iOS and Android... just not on Windows Phone.
To get around this in my app, I perform my native authentication (HttpClient) and then authenticate
again within the webbrowser control itself. Basically, load the login page into the browser, then submit the login form via eval of JavaScript, and when that finishes loading (valid
response), load the actual target page. This is a fragile and inefficient hack, but it seems to work.
Hope this helps...

Multiple set-cookies directives

Hi All- I'm testing against an http server that sends multiple set-cookies directives (there are 4 cookies total). As far as I can tell, it is legit HTTP to either send a single set-cookie directive with multiple cookies in it, or multiple set-cookies directives. I am getting erratic behavior. Using the wtk emulator, i am able to receive and process multiple set-cookies directives. Using some phones it works, on others it doesn't. I am trying to create a unit test for my code, and I am unable to figure out how to set up the classpath the same way the emulator does to work with multiple set-cookies directives.
I searched the jars in the wtk22 directory, and it appears that wtklib/emptyapi.zip, wtklib/gcf-op.jar, lib/midpapi10.jar and lib/midpapi20.jar all contain the HttpConnection class. I am guessing that the emulator is picking up a different implementation than my unit test or the phones that don't work? Has anyone encountered and solved this problem before? Is there a way at runtime to determine from which jar a class was loaded?
thanks,
Bleu

Silverlight 5 WebBrowser Control - Is the SL5 WebBrowser control is set to work in IE7 mode only? I have a 3rd party web site i'm hosting and now they will not work with IE 7 Compatibility mode. Looks like this control can't detect I'm setup for IE 9.

Silverlight 5 WebBrowser Control - Is the SL5 WebBrowser control is set to work in IE7 mode only? I have a 3rd party web site I'm hosting and now they will not work with IE 7 Compatibility mode. Looks like this control can't detect I'm setup for IE 9. I'm
running IE 11 with registry hack for IE 9. I think the SL5 webbrowser control is set to work only in IE 7. can some one verify this or tell me how to set the WebBrowser control up to run either IE8, 9, 10 or 11? I have same issue with machines running IE 8
and above. This Silverlight 5 application is running out of browser with the elevated privileges (hack) and at test certificates install in proper stores. This application has been running for 2.5 years. Vender switch on some changes a couple days ago that
broke this application. Help!!

Hi,
It seems there is nothing to do with IE mode.
Please make sure your link still can be accessed.
The WebBrowser displays HTML content in applications running in a Silverlight 4 or later out-of-browser applications or in Silverlight 5 in-browser trusted applications only.
For more infromation,please check link below:

SwapImage with Set cookie - Get Cookie , Optimizing for internet explorer ?

Hello
I have a soon- to -be -published website. The homepage, index has quite a lot of session - cookies on it, which are connected to swapimage behaviour. They work fine in firefox, opera, Safari and chrome, but in Internet explorer the swapping of the images takes a looooooot of time.....
Also, when I reload the page, some of the cookies are not retrieved, which only happens in Internet Explorer.
This is the inline javascript for the page:
<script type="text/javascript">
function MM_swapImgRestore() { //v3.0
var i,x,a=document.MM_sr; for(i=0;a&&i<a.length&&(x=a[i])&&x.oSrc;i++) x.src=x.oSrc;
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
    var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
    if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
function MM_findObj(n, d) { //v4.01
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
    d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document);
if(!x && d.getElementById) x=d.getElementById(n); return x;
function MM_swapImage() { //v3.0
var i,j=0,x,a=MM_swapImage.arguments; document.MM_sr=new Array; for(i=0;i<(a.length-2);i+=3)
   if ((x=MM_findObj(a[i]))!=null){document.MM_sr[j++]=x; if(!x.oSrc) x.oSrc=x.src; x.src=a[i+2];}

As you can see there are a lot of function calls with getElementById, and I'm thinking there has to be a more efficient way of doing this....... I am using an external cookieScript for setting and getting the cookies, but the swapImage is standard Dreamweaver.
I would be very happy if anybody could help me with this.. I know it is probably easy when you know how, but I don't, unfortunately :-(

Hi JMH_NG,
Thanks for the post and I hope your well today. I noticed you've not received any support so far.
It is possible in LabVIEW to access the ActiveX event callbacks
for the WebBrowser object. The "ActiveX Event Callback for IE.vi" is a
good example found in the Example Finder that demonstrates this
capability. The ability to poll whether the download is complete will
be completely dependent on the DWebBrowserEvents that the WebBrowser supports. FileDownload will notify when a download file download begins. From Microsoft's MSDN page,
"When the WebBrowser control is about to begin a download operation, it
fires the DWebBrowserEvents2:: DownloadBegin event." A DownloadComplete
event is also fired when the download operation finishes. From the
information I've found, it sounds like these events (and
ProgressChange) are only for page downloads and not for file downloads,
but they are your best bet. I would suggest inquiring on the MSDN Forum for more information on these events.
I hope this helps,
Kind Regards,
James.

Set cookie in webservice request

Hi,
Is there a way to set a cookie in a webservice request or include the HttpCookie in the service call ? Basically I am using Axis on client side to call a .NET webservice on a remote server and need to pass user data to the service in a cookie.
Thanks

Hi Santhiyaraman,
Webview control is in windows phone 8.1 runtime app, in windows phone 8 is webbrowser control.
Webbrowser control does not provide some properties or methods to add custom cookie, but we can do this using the javascript. Code snippet looks like the following.
private void setCookie(string name, string value, string path = "", string domain = "", bool isSecure=false, string expires = "")
var sb = new StringBuilder();
sb.AppendFormat("document.cookie = '{0}=\" + escape(\"{1}\")", name, value);
if (!String.IsNullOrEmpty(expires))
sb.AppendFormat(";expires=\"{0}\"", expires); // should be a GMTString
if (!String.IsNullOrEmpty(path))
sb.AppendFormat(";path=\"{0}\"", path);
if (!String.IsNullOrEmpty(domain))
sb.AppendFormat(";domain=\"{0}\"", domain);
if (isSecure)
sb.Append(";secure'");
var cookieJs = sb.ToString();
Debug.WriteLine(cookieJs);
webBrowser.InvokeScript(cookieJs);
You can find more information about it from

Set cookie in Webview in Windows Phone 8.0

The app we created runs as a webview control after initial login process. We have to send a cookie(secure httponly ) to server as part of request after first time login for consequent logins.
There is no solution provided to set cookie in web view. Can anybody share a sample to set cookie in webview control in Windows phone 8.0 (Silverlight app)?

How to open a pdf file with command in WebBrowser control?

Installed acrobat 6 or7 in my PC, then I load a WebBrowser control in IE to open a local pdf file with command line, such as "Page=3", and then open the same pdf file with WebBrowser control in other IE process, I found the command will affect other open and show operations in webbrowser. is it normal? That is to say, When i set command "Page=3", the second time WebBrowser still open pdf with command "Page=3",I think it is bad.

Hello:
Thanks for your reply. I installed Acrobat6.0 or 7.0 in my PC, then i load a WebBrowser Control in IE by Html, then open local pdf with different command by running IE. We can get the command in this website: http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf
First:open local pdf with command : oWebBrowser.Navigate("G:
PDF
07000001.pdf#Page=3&Pagemode=thumbs", null, null, null, null);
Second:Open the same local pdf with no command: oWebBrowser.Navigate("G:
PDF
07000001.pdf", null, null, null, null)
【Result】The first command "#Page=3&Pagemode=thumbs" will effect the way of showing pdf when second open. But, the phenomenon will not appear in Acrobat 8.0, 9.0, 10.0.

PrintSetup/Preview issue with WebBrowser control in 64bit applications

The WebBrowser Control appeared to be working well in a 64-bit VB.Net application I've been developing, until I looked more closely at what was happening when using the ShowPrintSetupDialog and ShowPrintPreviewDialog members. If I opened the print setup
dialog and changed the page size from A4 to 8.5 x 11, clicked ok, and then either reopened the page setup dialog or accessed it through the print preview dialog, the page size had returned to A4 and had not retained the 8.5 x 11 setting. However, if I rebuild
the application as 32-bit the changed setting is correctly retained. The code is being developed using Visual Studio 2012 Express running as administrator under 64-bit Windows 8.1 with 64bit Internet Explorer 11 installed as standard. Does anyone
know how to overcome this problem so users can confidently change the page size in a wholly 64-bit application and print via the WebBrowser control? Thanks in advance for any help you can provide.

I suppose you are using these methods WebBrowser.ShowPrintPreviewDialog Method and
WebBrowser.ShowPageSetupDialog Method.
Both methods show the below. Although why it would work 32 and not 64 is unknown to me.
.NET Framework Security
SecurityPermission

WPF WebBrowser Control Security Message After Loading Local XML File

When I use the .Source property of the WebBrowser control, it displays the XML file I pointed to, but then puts a security banner at the top, stating that some content has been disabled. I can't figure out how to stop that warning from appearing.
I've played with IE security settings, to no avail.
I've found some articles about putting a "mark of the web" tag inside the XML file, but I can't do that because the files are created by a 3rd-party application, and I can't edit all of them.
Isn't there a simple way to just turn off the feature for the WebBrowser control without messing with my IE security settings?
Thanks...
Ron Mittelman

Ok, I did exactly what you suggested. Brand new project. Instead of using the file dialog, I just hard-coded the path to my xml-type file directly, as your prior suggestion stated. The actual statement was:
string myFile = @"file://127.0.0.1/c$/data/local/JMPS/data/CRD CWD Routes/myFile.crd";
Then I used the proper code to set the Source property of the WebBrowser. The file is really, really there, I promise. Upon running, I get a dialog box saying that it "cannot find 'file://127.0.0.1/c$/data......."
So there is some reason this will not work. I am working in a high security area, so perhaps the machines are locked down to the extent that the method won't work?
Can you explain why this method *should* work? Why does using the IP address format defeat the security message?
Is there perhaps some other method? Some of the articles I read talked about putting a "mark of the web" tag inside the xml file. Is this a possible option? I can't really modify the files, but if I could get NavigateToStream
or NavigateToString methods to work, I could insert that tag inside the xml file contents. Unfortunately, as my other post states, I'm having a lot of challenges getting that to work also.
I think that too is possibly caused by how locked down our development PC's are.
Thanks...

Automating a Website with WebBrowser control, but proxy is getting in the way

Hi
I am trying to automate a website query through SSIS, I have a dll that uses the WebBrowser control to download the page, run the query and parse the returned page for detail.
This works well on my development machine, including in the Agent, but as soon as I try it on a server I run into issues with Proxy. I need to use a proxy to get out onto the internet, but the account that is running as the base is just a service account
so setting the Internet Settings in the registry fails because it hasn't really go a full user hive and as soon as I try to set it with Registry.SetValue I get Access Denied, when I look at the account it has no complete hive, hence the error
Any help much appretiated

Pdf from blob directly to webbrowser control without file create ???

my client(c#) fetches a blob filed from db containing a pdf document
if i save the fetched byte data in a file and set webBrowser.Navigate(fileSavedLoc); the pdf is displayed in the webbrowser control
is there a possibility to avoid the file create and show the fetched pdf byte stream directly in the webbrowser control (maybe by creating a html doc) ?
thx

Hi,
This is more of an ASP.NET question than an Oracle question.
As I understand it though, you'll want to create a Handler for that. There's an example of one that processes images stored in a database if you create a new Personal WebSite in VS2005 or VWD ( File > New > WebSite > Personal Web Site ). Look at Handler.ashx... in a nutshell it calls PhotoManager.GetPhoto to get the bytes of the picture, then passes those to the OutputStream with ContentType of "image/jpeg". You could do the same for pdf.
You'd then just call Handler.ashx with a query string to identify the pdf you need.
Hope it helps, corrections welcome.

Project Spartan and the WebBrowser control

I'm a C# WinForms developer working in Visual Studio 2010 and I use the WebBrowser control in my desktop applications for users to view web content through the
desktop app.
I have 2-questions related to the upcoming Project Spartan browser, which is supposed to replace IE as the browser.
Will the Spartan browser (or whatever its final name will be) continue to support the WebBrowser control in the toolbox? The control currently utilizes the functionality
of the user's existing IE browser. If IE continues to be present on new Windows 10 desktop systems along with Spartan, then it probably won't be an issue.
One issue the Web Browser Control on Windows has, is that it’s perpetually stuck in IE 7 rendering mode by default. This is can be seen in articles like
(see the section entitled Browser Emulation)
or
Web Browser Control
– Specifying the IE Version
or
WebBrowser ActiveX Control – Google Maps Invalid Character Scripting Error
This requires a registry setting to set its emulation mode. Making the setting in the registry works. However, I would like to "Future-Proof" my application
to account for any changes to the user's browser and Project Spartan certainly could prove to be a game changer if it won't support this development control.
2. Therefore, I would also like to know how Project Spartan will address browser emulation modes.
Thanks

Hello Sheng and thanks for your reply.
In your comments you stated that "the Trident-based WebBrowser class will continue to work." However, is the
existing WebBrowser control in my .Net Framework 4.0 Visual Studio 2010 toolbox, based on the "Trident WebBrowser class"?
That is my primary concern, as my applications, which use the browser control, utilize IE's functionality. If IE12 and Spartan will use a different rendering engine, then I have to wonder if applications making use of the .Net 4.0 WebBrowser control will
break.
Do your comments of both IE 12 and Spartan being based on Trident and EdgeHTML, imply that Microsoft will introduce a different browser toolbox control, or
will there continue to be backwards compatibility for the existing browser control? Thank you again for your insight.

Script error suppression in Access 2010 Webbrowser Control

I like the WebBrowser Control have an application where I use it to do online research and save the results, but on many sites, particularly University Sites, I get script errors. This is very annoying.
How can I suppress script errors in Access 2010 WebBrowser Control. Looked at the property controls and VBA does not contain the VB Suppress...script. I am at a complete loss.
Looked and Looked for solution on internet and no dice.
Help me Obi Wan (A.K.A. Albert Kallal) you're my only hope

Thanks for the kind thumbs up!
And with the recent purchase of the star wars franchise by Walt Disney, it's very possible we will see a new Star Wars movie in the not too distant future (or should I say in a galaxy not too far away?). So I'm actually looking forward to the possibility
of another star wars sequel and that would be lots of fun!
As for the script errors? Unfortunately, I don't think there is a solution.
You can check + ensure that the options in Internet explorer (advanced) are set to ensure that script errors and script debugging is disabled. However, THESE SETTINGS DO NOT carry over from Internet explorer into the web control on an access form. And in
fact you might even be using Firefox browser or something else. The web control in Access has a relative high degree of independence from your actual browser setting or even what Browser you're currently using. (and in most cases this is a good thing!).
This is a native control to Access.
If you're receiving the script errors without the user doing anything at all in that browser, I don't think you have much choice here (you can check the scriipt setttings in IE, but to my knowledge they do NOT apply). You have to see if the admin of the
web site can clean up the HTML to eliminate such errors.
Another possbile is to as others here suggest - launch the browser external as hyper link.

Setting cookies across domains

Hi there all,
I'm posting this in desperation to be honest, don't think
there is a cut'n'dried
answer to this one.
I've got a horrible situation, (don't ask why, it's far too
complex and to
be quite honest.. boring :) ).
I'm trying to "mesh" together a classic .asp with an asp.NET
site on 2
separate domains.
Basically I've got a page from the asp.NET site (eg.
www.something.co.uk)
displayed within an iframe on the .asp (eg
www.another.co.uk). So far so
good.
I need to set a cookie on www.another.co.uk and be able to
read it, or
replicate it on www.something.co.uk. Because they are not
sub-domains I can't
set the cookie direct because of security restrictions.
So, I thought I could pass a URL variable across to
www.something.co.uk via
the iframe URL, and then using javascript to read said URL
variable and set
a cookie on the www.something.co.uk domain. No go. Suspect
there is yet
again security restrictions to setting cookies across domains
using iframe.
So I'm kind of stuck. Can anybody suggest anything please,
bearing in mind I
have very limited control over the asp.NET
(www.something.co.uk) site, so
any solution I come up with needs to be using javascript.
Major sized thanks in advance.
@ndyB

You could also pass the id as a hidden field in a form.
Have the link call a JavaScript function. The JavaScript funcition could access the cookie and pull out the id. The function would then set a hidden field in a form to the id value and then Post the form to the secure server.
The form would only have hidden fields so it could be tagged on the end of the HTML page and the user would never know it was there.
