ScribeStation.com has open beta testing of the new Livescribe acquisition client which can take data off of your Livescribe Pulse pen and convert it to many usable formats. Go to http://www.scribestation.com for more information and become a beta tester today!

I deployed a multi-user web application today and for some reason the session was being SHARED between users. Not sure what is causing this. It was a simple application that only needed the session for some non-confidential data so I just threw them into a cookie for now. I am across this interesting link that has some good information so I figured I would post it:

I have been getting a lot of requests with people looking to remove the stroke data (X&Y) from the pen. I am currently writing and releasing an acquisition client that will be available at www.scribestation.com and allow users of the LiveScribe Pulse to easily access their stroke and image data on their pen.

I also have plans to expose an API that will allow your applications to work with the XML data.

I plan to have this site released within a month.... so hang in there!

Thanks for all your support, comments and feedback!

Creating an instance of the COM component with CLSID {AAC46A37-9229-4FC0-8CCE-4497569BF4D1} from the IClassFactory failed due to the following error: 80040235

To resolve this, I went to:

http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=080184dd-5e92-4464-b907-10762e9f918b

And downloaded the Microsoft Windows XP Tablet PC Edition 2005 Recognizer Pack. Install that and you will no longer get that error.

Hope that helps, would have saved me 4 hours :-)

XML parsing: line 1, character 45, unable to switch the encoding

I was simply sending a string to a stored proc thinking that would work (it was a string of valid XML)... I was wrong. I did some research and solved the problem by wrapping up the XML String into a SQL XML datatype.

System.Data.SqlTypes.SqlXml xmlSafe = new System.Data.SqlTypes.SqlXml(new System.Xml.XmlTextReader(xmlAsString, System.Xml.XmlNodeType.Document, null));

Sure, it's simple enough but I haven't used the XML type before.


LS.Desktop.AFDDB.LSDocument doc = LS.Desktop.AFDDB.LSDocument.LoadDocument("YOURPATHHERE.AFD");

//Check for strokes
if (doc.HasStrokes(0))
{
Console.WriteLine("Has Strokes!");

//Go through each page
for (int pageno = 0; pageno < doc.pageInstances.Count; pageno++)
{
Console.WriteLine(string.Format("Page No {0}", pageno));

//Go through each stroke
for (int strokeno = 0; strokeno < doc.pageInstances[pageno].NumStrokes; strokeno++)
{
Console.WriteLine(string.Format("\tStroke No {0}", strokeno));

//Go through the points
foreach (Point p in doc.pageInstances[pageno].GetStroke(strokeno).Points)
{
Console.WriteLine(string.Format("\t\t({0}, {1})", p.X, p.Y));
}
}
}
}
else
{
Console.WriteLine("No Strokes!");
}


You can use that object to get other things too. If you have any questions or need help just send me an e-mail or post a comment. I would be glad to assist.

Locate your AFD files. By default they are located at "C:\Program Files\Livescribe\Livescribe Desktop\Printing". You will see AFD files here along with a "Printables.xml" files. Go ahead and copy the "LS_PYON_TestPage.afd" and the "Printables.xml" for backup so that you can restore them later if need be. Now, on to the file changing.

Rename "LS_PYON_TestPage.afd" to "MyTestForm.afd".

Open "Printables.xml" in notepad. Change the first Printable Node

from:

<Notepad id="1" guid="0x66d4de896a2c6c85" filename="LS_PYON_TestPage.afd" numberofpages="1" menutext="T&est Page (1 Page)..." menuorder="5" mustexist="True" />

to:

<Notepad id="1" guid="0x66d4de896a2c6c85" filename="MyTestForm.afd" numberofpages="1" menutext="Wicked Cool Document..." menuorder="5" mustexist="True" />

Now, you can open the LiveScribe Desktop and see your form listed on the menu. That is the first step... the next is actually making that document look like one you want.

Go back to the "C:\Program Files\Livescribe\Livescribe Desktop\Printing" folder, rename "MyTestForm.afd" to "MyTestForm.zip".

Extract the "MyTestForm.zip" files to a directory. Look through the files, you will see a bunch of different things. The AFD (as discovered previously) stores a bunch of information. I am not sure what it all is, or even if stroke data that I was looking for would be in there but, there are some good things in here.

Since we want to make our own custom looking form, navigate to the "\userdata\lsac_data" in the extracted file. There you will see "LS_PYON_TestPage.v1.png", that is the form background image. Change that to whatever you would like using Photoshop, or any other imaging tool. There is also a EPS file in "pages\resources", open and change that as well. Once your modifications have been completed go ahead and copy the changed file into the "MyTestForm.zip" file using a zip utility (Winzip, PKZIP, etc.). Finally, rename the file to "MyTestForm.afd".

I figured that would do the trick but the document is not printing to the printer. It says it is but then it doesn't print. So, I am looking into why that could be. I am thinking it has to do with my EPS editing. I am probably not exporting properly. There might also be some kind of check on the AFD file. I'm still not sure.... Any ideas? I plan to revist this soon. I have to get back to getting stroke data out of the AFD for now...
