• Detect marker with opencv and python

  - by Mitch

  Hi im trying to detect a marker in a webcam video feed and overlay it with a 3d object - pretty much exactly like this: http://www.morethantechnical.com/2009/06/28/augmented-reality-with-nyartoolkit-opencv-opengl/ i know artoolkit is the best module for this, but i was hoping to just use opencv in python since i dont know nearly enough c/c++ to be able to use artoolkit. im hoping someone will be able to get me on the right track towards detecting the marker and determining its location and orientation etc since i have no idea how best to go about this or what functions i should be using thanks mitch

• How to use MongoRegex (MongoDB C# Driver)

  - by Hery

  Has anyone have any idea how to use MongoRegex for the document search? I attempted this, but returns nothing back: var spec = new Document(); spec.Add("Name", new MongoRegex("/" + searchKey + "*/", "i")); collection.Find(spec) Wondering why it doesn't work, I tried to execute following command from the console: db.things.find({"Name":/john*/i}) /* WORKS */ db.things.find({"Name":"/john*/i"}) /* DOESN'T WORK */ Is that possible that the driver applies double quotation to the regex? Thanks..

• MS Access 2003 - Unbound Form uses INSERT statement to save to table; what about subforms?

  - by Justin

  So I have an unbound form that I use to save data to a table on button click. Is there a way I can have subforms for entry that will allow me to save data to the table within that same button click? Basically I want to add more entry options for the user, and while I know other ways to do it, I am particularly curious about doing it this way (if it can be done). So lets say the 'parent form' is frmMain. And there are two child forms "sub1" and "sub2". Just for example sake lets say on frmMain there are two text boxes: txtTitle & txtAuthor. sub1 and sub2 both have a text Box on them that represent something like prices. The idea is Title & author of a book, and then a price at each store (simplified). So I tried this (because I thought it was worth a shot): Dim db as DAO.database Dim sql as String sql = "INSERT INTO (Title, Author, PriceA, PriceB) VALUES (" if not isnull(me.txtTitle) then sql = sql & """" & me.txtTitle & """," Else sql = sql & " NULL," End If if not IsNull(me.txtAuthor) then sql = sql & " """ & me.txtAuthor & """," else sql = sql & " NULL," end if if not IsNull (forms!sub1.txtPrice) then sql = sql & " """ & forms!sub1.txtPrice & """," else sql = sql & " NULL," end if without finishing the code, i think you may see the GOTCHA i am headed for. I tried this and got an "Access cannot find the form "" ". I think I can pretty much see why on this approach too, because when I click the button that calls the new sub form into the parent form, the values that were just entered are not held/saved as sub1 closes and sub2 opens. I should mention that the idea above is not intended to be a one or the other approach, rather both sub forms used everytime. so this is an example. i want to use this method (if possible) to have about 7 different sub form choices in one form, and be able to save to a table via a SQL statement. I realize that there may be better ways, but I am just wondering if I can get there with this approach out of curiousity. Thanks as always!

  I am drawing on a canvas with the following line: ctx.drawImage(compositeImage, 0, 0, image.width, image.height, i, j, scaledCompositeImageWidth, scaledCompositeImageHeight); This code has executed error free on Safari, Chrome, Firefox (and even IE using google's excanvas library).

• CodeIgniter extend user's session expiration time

  - by spacemonkey

  Hi, Is it possible to extend user's session expiration time in CI. What I want to do is, by default every user's session cookie lasts for example 1 day, but every time user visits the site his session expiration time is extended by one more day. I don't know if it is a good idea to do this, maybe I should just set cookies life time for like a week and that's it? Thanks!

  I have a website that emails a link to the invoice when an order is complete. The link should be http://mysite.com/QuoteAndBook/Confirmation?orderId=123 But for some reason it is: http://204435-204435/QuoteAndBook/Confirmation?orderId=123 The host portion of the link is generated using HttpContext.Current.Request.Url.Host but I would expect that to return "mysite.com", not "204435-204435". Any idea what's going on?
