Apose.Words ImportNode ignores font formatting when appendingchild

I am currently using Aspose.Words to open a document, pull content between a bookmark start and a bookmark end and then place that content into another document. The issue that I'm having is that when using the ImportNode method is imports onto my document but changes all of the fonts from Calibri to Times New Roman and changes the font size from whatever it was on the original document to 12pt.
The way I'm obtaining the content from the bookmark is by using the Aspose ExtractContent method.
Because I'm having the issue with the ImportNode stripping my font formatting I tried making some adjustments and saving each node to an HTML string using ToString(HtmlSaveOptions). This works mostly but the problem with this is it is stripping out my returns on the word document so none of my text has the appropriate spacing. My returns end up coming in as HTML in the following format
"<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:11pt\"><span style=\"font-family:Calibri; display:none; -aw-import:ignore\"> </span></p>"
When using
DocumentBuilder.InsertHtml("<p style=\"margin-top:0pt; margin-bottom:8pt; line-height:108%; font-size:11pt\"><span style=\"font-family:Calibri; display:none; -aw-import:ignore\"> </span></p>");
it does not correctly add the return on the word document.
Here is the code I'm using, please forgive the comments etc... this has been my attempts at correcting this.

Saving each node to HTML and then inserting them into the destination document is not a good idea. Because not all nodes can be properly saved to HTML and some formatting can be lost after Aspose.Words DOM -> HTML -> Aspose.Words DOM roundtrip.
Regarding the original issue, the problem might occur because you are using ImportFormatMode.UseDestinationStyles, in this case styles and default of the destination document are used and font might be changed. If you need to keep the source document formatting, you should use ImportFormatMode.KeepSourceFormatting.
If the problem occurs even with ImportFormatMode.KeepSourceFormatting this must be a bug and you should report this to Aspose.Words staff in the support forum.

How to inject styles to a page using IE addon

I am trying to convert a content script I wrote for Google Chrome into an IE Addon, mainly using the code in this answer.
I needed to inject an stylesheet and, I found a way to do it using Javascript. I thought I might be able to do the same using C#. Here's my code:
[ComVisible(true)]
[Guid(/* replaced */)]
[ClassInterface(ClassInterfaceType.None)]
public class SimpleBHO: IObjectWithSite
{
private WebBrowser webBrowser;
void webBrowser_DocumentComplete(object pDisp, ref object URL)
{
var document2 = webBrowser.Document as IHTMLDocument2;
var document3 = webBrowser.Document as IHTMLDocument3;
// trying to add a '<style>' element to the header. this does not work.
var style = document2.createElement("style");
style.innerHTML = ".foo { background-color: red; }";// this line is the culprit!
style.setAttribute("type", "text/css");
var headCollection = document3.getElementsByTagName("head");
var head = headCollection.item(0, 0) as IHTMLDOMNode;
var result = head.appendChild(style as IHTMLDOMNode);
// trying to repace an element in the body. this part works if
// adding style succeeds.
var journalCollection = document3.getElementsByName("elem_id");
var journal = journalCollection.item(0, 0) as IHTMLElement;
journal.innerHTML = "<div class=\"foo\">Replaced!</div>";
// trying to execute some JavaScript. this part works as well if
// adding style succeeds.
document2.parentWindow.execScript("alert('Hi!')");
}
int IObjectWithSite.SetSite(object site)
{
if (site != null)
{
webBrowser = (WebBrowser)site;
webBrowser.DocumentComplete += new DWebBrowserEvents2_DocumentCompleteEventHandler(webBrowser_DocumentComplete);
}
else
{
webBrowser.DocumentComplete -= new DWebBrowserEvents2_DocumentCompleteEventHandler(webBrowser_DocumentComplete);
webBrowser = null;
}
return 0;
}
/* some code (e.g.: IObjectWithSite.SetSite) omitted to improve clarity */
}
If I just comment out the following line...
style.innerHTML = ".foo { background-color: red; }";
... the rest of the code executes perfectly (The element #elem_id is replaced and the JavaScript I injected is executed).
What am I doing wrong when trying to inject the stylesheet? Is this even possible?
EDIT: I found out that the site I'm trying to inject CSS requests Document Mode 5, and when Compatibility view is disabled, my code works perfectly. But how do I make it to work even when compatibility view is enabled?

After lot of experimenting, I found out that only failsafe way to inject stylesheets to inject them using JavaScript, which is executed with IHTMLWindow2.execScript().
I used following JavaScript:
var style = document.createElement('style');
document.getElementsByTagName('head')[0].appendChild(style);
var sheet = style.styleSheet || style.sheet;
if (sheet.insertRule) {
sheet.insertRule('.foo { background-color: red; }', 0);
} else if (sheet.addRule) {
sheet.addRule('.foo', 'background-color: red;', 0);
}
The above JavaScript was executed in the following fashion:
// This code is written inside a BHO written in C#
var document2 = webBrowser.Document as IHTMLDocument2;
document2.parentWindow.execScript(#"
/* Here, we have the same JavaScript mentioned above */
var style = docu....
...
}");
document2.parentWindow.execScript("alert('Hi!')");

Add CSS File in DLL (Class Library)

I have a Class Library project named "AddJsFunction" which contains a class where I am including all related JS, CSS and Image files. Below is the IncludeJsFile method inside the above mentioned class where I am adding all the Javascript files which works as expected.
public void IncludeJsFile(Page pg)
{
pg.ClientScript.RegisterClientScriptInclude(this.GetType(), "Test2", pg.ClientScript.GetWebResourceUrl(this.GetType(), "AddJsFunction.queue.js"));
string csslink2 = "<script type='text/javascript' language='javascript' src='" + pg.ClientScript.GetWebResourceUrl(this.GetType(), "AddJsFunction.queue.js") + "' />";
LiteralControl include2 = new LiteralControl(csslink2);
pg.Header.Controls.Add(include2);
}
Same way I want to embed the CSS files which i tried to include like shown above but that is not working and I need some help to do the same.
Thanks,
VY.

From Is there a ClientScriptManager.RegisterClientScriptInclude equivalent for CSS:
HtmlLink link = new HtmlLink();
link.Href = "Cases/EditStyles.css";
link.Attributes.Add("type", "text/css");
link.Attributes.Add("rel", "stylesheet");
//check if it exsists on the page header control first
foreach (Control control in pg.Header.Controls)
{
if ((control is HtmlLink) &&
(control as HtmlLink).Href == href)
{
return true;
}
}
pg.Header.Controls.Add(link);

Issue regarding add html data to web browser control repeatedly

This way i try to add html data to web browser control.
private void Adddata()
{
webBrowser1.DocumentText =
"<html><body>Please enter your name:<br/>" +
"<input type='text' name='userName'/><br/>" +
"<a href='http://www.microsoft.com'>continue</a>" +
"</body></html>";
}
This works but when i call the Adddata() routine repeatedly then only first time data gets added but from the next time no data is getting added. i just want to add the data repeatedly. is there any way out.

You can use this:
webBrowser1.DocumentText +=
But now when you can't add this code with many body and html tags.
Always build new String with one html and body tag.
Just append html code inside.

Change
webBrowser1.DocumentText = //blah
to
webBrowser1.DocumentText += //blah
Well, not really. It wouldn't be the best of ideas to do that for html. What I would do is
//in class def
bool firstTime;
//in method
bool firstTimeLcl = firstTime
firstTime = false;
if (firstTimeLcl)
{
//write header
}
else
{
String.Replace(/*closing tags*/, "");
}
//write everything within body
//write closing tags

Syntax for using C# to create multiple HTML attributes via attributes.add

This is long-winded but should be easy for one of you knowledgable chaps to workout.
I have a DotNetNuke webpage with a dynamic login link. If you are not logged in the link will be 'login' and have the appropriate URL to a login popup. If you are logged in the link will be 'logout' and likewise have an the appropriate URL to the webpage that handles logout.
When the page determines if you are logged in or not the HTML link gets built with an attribute of : onclick="return dnnModal.show('http://blahblah.com....').
The code that does this:
loginLink.Attributes.Add(" onclick", "return " + UrlUtils.PopUpUrl(loginLink.NavigateUrl, this, PortalSettings, true, false, 200, 550));
Regardless of what the link is, the ID and Class always remain the same. My problem is that I would like to replace the login text with an image, infact a different image for login and logout. The issue here is that because the ID and Class stay the same I can't just do it via CSS as I normally would, but I have been able to style classes based on their attributes. I have tested this by finding out the output of the creation of the HTML link and styling the class based on the 'href' attribute for example:
a #dnn_dnnLogin_loginLink .LoginLink [href="http://some very very long dynamically created URL.aspx"]{ styles here }
The problem with this is the login/logout links change based on what page you are currently on.
I do know that each of the two rendered options has a uniqe attribue that I could style and that's their "Text" attribute. So quite simply how do I add this attribute to be rendered in HTML so that I can style it with CSS?
I have tried several variations such as:
loginLink.Attributes.Add(" onclick", "return " + UrlUtils.PopUpUrl(loginLink.NavigateUrl, this, PortalSettings, true, false, 200, 550) " Text", + loginLink.Text);
In the hope that what would be rendered would be something like:
onclick="return dnnModal.show('http://localhost/CPD/tabid/87/ctl/Login/Default.aspx?returnurl=%2fCPD.aspx&popUp=true',/*showReturn*/true,200,550,true,'')" Text="Login"
So I could style:
a #dnn_dnnLogin_loginLink .LoginLink [Text="Login"]{styles here}
a #dnn_dnnLogin_loginLink .LoginLink [Text="Logout"]{styles here}
But instead I get a generic error. I have tried various ways of writing the line without success, I just don't know the syntax.
Could someone point me in the right direction? I so hope I'm not barking up the wrong tree as this would be a really simple solution to my initial problem.
Thanks,

CSS classes are just designed for this purpose, and they are supported by all browsers that use CSS styling (even very old ones). You don't have to fight around with obscure selectors that are referencing some link that could change and break your styling again.
Since you said you already have a class assigned to these tags, you just want to specify an additional one. You can have more than one class assinged to a tag. See the W3C css class page for more info, in section 'Attribute Values':
Specifies one or more class names for an element. To specify multiple
classes, separate the class names with a space, e.g. . This allows you to combine several CSS classes for one
HTML element.
You can set the second class simply by appending it to the WebControl.CssClass string, separated by a space:
loginLink.CssClass = loginLink.CssClass + " login";
or
loginLink.CssClass = loginLink.CssClass + " logout";
this way you can access it via a single class selector or even the multiple class selector (only selects those tags that have both classes assigned) in your CSS style sheet:
.LoginLink.login { /* styles here */ }
.LoginLink.logout { /* styles here */ }

The text on the login/logout button is not stored in the Text="" attribute, but in the InnerHTML node. So your CSS selector would not apply. (I also think that the spacings in the selector are wrong, and that this solution would not support multilingual buttons, etc.)
Usually this type of styling would be implemented by in the Skin Editor (Admin/Skins/scroll down to section Skin Designer), where you select Skin or Container, File, Token=LOGIN, Setting=Text and LogoffText, and add a value src=path/to/a.gif. However, the skin designer seems to be broken in 6.1.x (bug report)
You might still try and have a look at the login.ascx and login.ascx.cs files in the admin\Skins directory of your DNN installation. Edit the code to assign loginLink.ImageUrl depending on Request.IsAuthenticated.
