*******************************************************************************
KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: 80000004, The exception code that was not handled
Arg2: ffdff2a5, The address that the exception occurred at
Arg3: a9c34d48, Trap Frame
Arg4: 00000000

The service name can be different: av.exe, scvhost.ext,..
I know that is due to the a driver does not process STATUS_SINGLE_STEP exception.
Is any idea how to find wrong driver? There is no stack and module name in the dump...
I tried to run the Mirosoft Driver Verifier with standart flags and all drivers without Microsoft drivers, dump listing is above.

Sitecore Multiline Text field, convert string to html

I am using C# MVC Razor.
Question:
I have a Multiline Text field with HTML, I use this field because I want no formatting at all. I just want to output the raw value.
example:
<path d="M610.7 357.9c-2.4-1.2-16.6-8.6-18.7-9.7 -7.5-3.8-10.1-7.2-10.1-12.9 0-8 6.5-13.1 16.7-13.1 6 0 11.7 2.6 15.1 4.5 0.6 0.3 1.3 0.5 2.1 0.5 2.4 0 4.3-1.9 4.3-4.3 0-1.6-0.9-3-2.2-3.7 -4.3-2.4-11.5-5.6-19.3-5.6 -14.9 0-25.3 8.9-25.3 21.7 0 11.5 7.5 16.9 14.9 20.7 2.1 1.1 16.5 8.5 18.7 9.6 5.7 3 8.9 7.5 8.9 12.6 0 6.9-5.9 14.3-16.7 14.3 -10.5 0-18.7-7.1-21-9.2l-0.7-0.6 -6.4 5.8 0.8 0.7c2.8 2.8 13.2 12 27.3 12 15.8 0 25.3-11.6 25.3-22.9C624.3 369.9 619.3 362.5 610.7 357.9z" />
Normally it outputs as:
<path d="M610.7 357.9c-2.4-1.2-16.6-8.6-18.7-9.7 -7.5-3.8-10.1-7.2-10.1-12.9 0-8 6.5-13.1 16.7-13.1 6 0 11.7 2.6 15.1 4.5 0.6 0.3 1.3 0.5 2.1 0.5 2.4 0 4.3-1.9 4.3-4.3 0-1.6-0.9-3-2.2-3.7 -4.3-2.4-11.5-5.6-19.3-5.6 -14.9 0-25.3 8.9-25.3 21.7 0 11.5 7.5 16.9 14.9 20.7 2.1 1.1 16.5 8.5 18.7 9.6 5.7 3 8.9 7.5 8.9 12.6 0 6.9-5.9 14.3-16.7 14.3 -10.5 0-18.7-7.1-21-9.2l-0.7-0.6 -6.4 5.8 0.8 0.7c2.8 2.8 13.2 12 27.3 12 15.8 0 25.3-11.6 25.3-22.9C624.3 369.9 619.3 362.5 610.7 357.9z" />
So I wrapped the value in:
#WebUtility.HtmlDecode(complexShapes)
With no change. How can I get this value as is?

If your model values are set as follows in your controller:
model.ComplexShapes =
"<path d=\"M610.7 357.9c-2.4-1.2-16.6-8.6-18.7-9.7 -7.5-3.8-10.1-7.2-10.1-12.9 0-8 6.5-13.1 16.7-13.1 6 0 11.7 2.6 15.1 4.5 0.6 0.3 1.3 0.5 2.1 0.5 2.4 0 4.3-1.9 4.3-4.3 0-1.6-0.9-3-2.2-3.7 -4.3-2.4-11.5-5.6-19.3-5.6 -14.9 0-25.3 8.9-25.3 21.7 0 11.5 7.5 16.9 14.9 20.7 2.1 1.1 16.5 8.5 18.7 9.6 5.7 3 8.9 7.5 8.9 12.6 0 6.9-5.9 14.3-16.7 14.3 -10.5 0-18.7-7.1-21-9.2l-0.7-0.6 -6.4 5.8 0.8 0.7c2.8 2.8 13.2 12 27.3 12 15.8 0 25.3-11.6 25.3-22.9C624.3 369.9 619.3 362.5 610.7 357.9z\" />";
You can simply use #HtmlRaw to output it:
#Html.Raw(Model.ComplexShapes)
Screen Grab
Working Fiddle

Difficult to say without seeing your code that actually handles the field value and returns it.
Normally you would do something like this:
return new HtmlString(myFieldValue);
to instruct the framework that the string is ready to present as-is.

FFMPEG - Scrambled Output converting from VOB with ffmpeg

I've concatenated a series of VOB files from a DVD into a single VOB file and I am trying to convert it to MP4 or other similar format. I see a lot of errors when converting and the output appears scrambled.

I'm guessing this is CSS scrambling and I need to do some sort of DeCSS. Does FFMpeg have an option for this? Cringe if you'd like, but is there C# source to achieve this?
My end goal is really just to get some DVDs that I own onto my media server. I've tried a few demo-ware products with limited success including Acala DVD Ripper, Click to Disk, AVIDemux to name a few. I even paid for a couple of them to get the full version, but Acala only works for about half of my DVDs and Click to Disk can decode the VOB, but I need to use FFMpeg to convert. I'd like to have it all in one app that works and I am willing to write some code for it.

HtmlAgilityPack Save Process Not Letting Go Of File

I am saving some of the rendered html of a web site by overriding the Render method and using HtmlAgilityPack. Here is the code:
protected override void Render(HtmlTextWriter writer)
{
using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new StringWriter()))
{
base.Render(htmlwriter);
string output= htmlwriter.InnerWriter.ToString();
var doc = new HtmlDocument();
doc.LoadHtml(output);
doc.Save(currDir + "\\" + reportDir + "\\dashboardTable.html");
}
}
However, some process does not let go of the saved file and I am unable to delete it from the server. Does anyone know of an HtmlAgilityPack issue that would cause this?
Any advice is appreciated.
Regards.
EDIT:
I have tried both of the methods suggested. I can't tell if they are the solution yet because my app is frozen on the server due to the files I can't delete. However, when I use these solutions on my own machine, the rendered HTML does not save as an HTML table anymore but rather like this:

where only the text data has been saved and all of the HTML and CSS is missing. If I just use doc.Save() I get an exact representation of the table as it displays on the website.

Try this instead. Maybe the Save method isn't closing the underlying stream.
using( FileStream stream = File.OpenWrite( currDir + "\\" + reportDir + "\\dashboardTable.html" ) ){
doc.Save(stream);
stream.Close();
}

Edit
Per #L.B's comments it appears that HtmlAgilityPack does use a using block as in my example so it will be ensuring that the stream gets closed.
Thus as I suggested at the end of my original answer this must be a server environment problem
Original Answer
This may be some sort of bug with HtmlAgilityPack - you may want to report it to the developers.
However to eliminate that possibility you may want to consider explicitly controlling the creation of the StreamWriter for the file so you are explicitly closing it yourself. Replace this line:
doc.Save(currDir + "\\" + reportDir + "\\dashboardTable.html");
With the following:
using (StreamWriter fileWriter = new StreamWriter(currDir + "\\" + reportDir + "\\dashboardTable.html"))
{
doc.Save(fileWriter);
fileWriter.Close();
}
If the issue still persists even with this change then that would suggest an issue with your server environment rather than an issue with HtmlAgilityPack. Btw to test if this change makes a difference you should start from a clean server environment rather than one where you are already having issues deleting the file in question.

Saving A Specific Node As HTML Using HtmlAgilityPack

I have a web site that displays a table along with some buttons, navigation tabs, etc. Using HtmlAgilityPack I would like to save only the node containing the table (a div) to a .html file. I have been experimenting with this code:
string dashboard = doc.DocumentNode.SelectSingleNode("//div[#id='Dashboard']").InnerHtml;
doc.LoadHtml(dashboard);
doc.Save(currDir + "\\dashboardOutputFile.html");
But this only preserves the text components of the table and none of its layout/display information. I have tried adding a Doctype declaration as well as enclosing html and body tags to the dashboard string but it has no effect.
Any advice is appreciated.
Regards.
EDIT:
I should be more explicit. I am capturing the html of my page by overriding the Render method:
protected override void Render(HtmlTextWriter writer)
{
using (HtmlTextWriter htmlwriter = new HtmlTextWriter(new StringWriter()))
{
base.Render(htmlwriter);
string renderedContent = htmlwriter.InnerWriter.ToString();
var doc = new HtmlDocument();
doc.LoadHtml(renderedContent);
try
{
string dashboard = doc.DocumentNode.SelectSingleNode("//div[#id='Dashboard']").InnerHtml;
dashboard = "<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"><br><html xmlns=\"http://www.w3.org/1999/xhtml\"><head></head><body><div><br>" + dashboard + "<br></div></body></html>";
doc.LoadHtml(dashboard);
doc.Save(currDir + "\\dashboardOutputFile.html");
}
catch (NullReferenceException ex)
{
// Do nothing.
}
writer.Write(renderedContent);
}
}
To the best of my knowledge the string "dashboard" should contain a complete HTML page after this. However the resulting .html file displays like this:

Only the text of the table cells is being displayed. There is no table layout, no background colours, etc. Even when I copy the file into JSFiddle it displays like this. What am I missing to make this a complete HTML page?

There's probably a css file linked into the original html not being read in your downloaded page.
